Referring toand, a turntable adjustment buckleaccording to a first embodiment of the present disclosure includes a first buckle elementand a second buckle element, wherein the first buckle elementand the second buckle elementcan be assembled with each other, and the second buckle elementcan rotate relative to the first buckle element.

Please refer toandtogether. The first buckle elementincludes a base, an annular wall, a first matching portion, an accommodating space, two limiting portionsand two first through holes.

The baseis roughly in the shape of a disk and is used to fix or sew to an article. The article may be, for example, a clothing fabric, a cuff, a coat hood, leather goods, a plastic shell, a protective gear, a backpack, a bag, a helmet, a raincoat, or a footwear and the like, and the basemay be slightly curved so as to be completely attached to an article, but the present disclosure is not limited to as such.

The annular wallextends vertically outward from the base, and the cross section of the annular wallis in the shape of a circular ring. The first matching portionis disposed in the annular wall, and the accommodating spaceis surrounded and defined by the annular walland the first matching portion. The first matching portionhas a connecting portion, two elastic portionsand two tooth portions. The connecting portionis roughly H-shaped and is disposed in the annular wall, and can be roughly coplanar with the base(as shown in). The elastic portionsare roughly in the shape of a square sheet, and connected to the connecting portionopposite to each other. For example, one side of each elastic portionis connected to the connecting portion, and the other three sides of each elastic portionare not connected to the connecting portion. Thereby, the elastic portionscan generate an elastic force when deformed by a force. The tooth portionsare respectively disposed on the elastic portionsand face the accommodating space.

Please refer to, each tooth portionhas an inclined surfaceand a stopping surfaceadjacent to the inclined surface. The inclined surfaceand the stopping surfaceare respectively obliquely intersected with a surfaceof each elastic portion, and the area of the inclined surfaceis larger than the area of the stopping surface. Accordingly, the cross section of each tooth portionis roughly triangular, and an inclination angle of the inclined surfacerelative to the surfaceof each elastic portionis smaller than an inclination angle of the stopping surfacerelative to the surfaceof each elastic portion.

The two limiting portionsare roughly arc-shaped blocks. The two limiting portionsextend outward from the inner side of the annular wall, correspond to each other, face the accommodating space, and are spaced apart from the first matching portion. The two first through holesare formed through the annular walland correspond to each other.

Please refer toandtogether. The second buckle elementincludes an operating portion, a column, a second matching portionand a second through hole.

The operating portionis roughly in the shape of a disk. The edge of the operating portionhas a plurality of recessed grooves, which can provide friction when a user holds the operating portionto rotate, pull up, or press down. The operating portionis correspondingly disposed at the top of the annular wall. The columnis roughly cylindrical, extends outward from the operating portionand is located in the accommodating space. The second matching portionis disposed at the end of the columnand located in the accommodating space, and is assembled with the first matching portion.

The second matching portionhas a turntable bodyand a plurality of positioning grooves. The turntable bodyis roughly in the shape of a disk. The plurality of positioning groovesare respectively formed by recessing from a surface of the turntable bodyand are spaced apart from each other, and the tooth portionsare accommodated therein. In one embodiment, the number of the positioning groovesis 8, and the positioning groovesare arranged in a ring or radial shape at intervals from each other, but the present disclosure is not limited to as such. Please refer to, each positioning groovehas a pushing surfaceand a limiting surfaceopposite to the pushing surface. The pushing surfaceand the limiting surfaceare respectively obliquely intersected with a bottom surfaceof the positioning groove, so that the cross section of the positioning grooveis roughly an isosceles trapezoid, and an inclination angle of the limiting surfacerelative to the bottom surfaceof each positioning grooveis substantially equal to an inclination angle of the stopping surfacerelative to the bottom surfaceof each positioning groove. The second through holeis formed through the column, and the through direction thereof is parallel to the radial direction of the column.

Please refer to,and. When the first buckle elementand the second buckle elementare assembled with each other, the second matching portionis pushed into the accommodating spacein the annular wall. At this time, the periphery of the turntable bodyand the top surface of the limiting portioncan have corresponding inclined surfaces respectively, so that the second matching portioncan slightly squeeze the limiting portionand slide into between the limiting portionand the first matching portion, and the two tooth portionsare respectively completely accommodated in two of the plurality of positioning grooves. At this time, the inclined surfacecorresponds to the pushing surface, and the stopping surfacecorresponds to the limiting surfaceand is engaged with the limiting surface. Since the distance between the limiting portionand the first matching portionis approximately equal to the thickness of the second matching portionof the second buckle element, the second matching portionis limited by the limiting portionso that the second buckle elementcannot be easily separated from the first buckle element.

When the two first through holesand the second through holeare connected, a ropecan be inserted into the first through holesand the second through hole. At this time, the ropeis not wound around the columnand can move relative to the first buckle elementand the second buckle element. When the ropeis to be wound around the column, the second buckle elementcan be operated to rotate relative to the first buckle elementalong a fastening direction R(as shown in). In the fastening direction R, since the area of the inclined surfaceis larger than the area of the stopping surface, the pushing surfacedoes not engage with the inclined surface. Therefore, the user can apply a little force to make the pushing surfaceslide on the inclined surface, and make the pushing surfaceand the inclined surfaceoffset from each other. The elastic portionis pressed downward and deformed until the pushing surfaceslides into the next adjacent positioning groove, and then the elastic portionrebounds. At this time, the ropecan be wound around the column. When the ropeis to be released from the column, the second buckle elementcan be operated to rotate relative to the first buckle elementalong a releasing direction R(as shown in). In the releasing direction R, since the stopping surfaceengages the limiting surface, the user must overcome the resistance generated between the stopping surfaceand the limiting surfaceengaged with the stopping surface. Therefore, a greater force than that in the fastening direction Rmust be applied to allow the stopping surfaceand the limiting surfaceto be offset from each other. The elastic portionis pressed downward and deformed until the stopping surfaceslides into the next adjacent positioning groove, and then the elastic portionrebounds. At this time, the ropecan be loosened from the column.

In other words, the engagement strength between the first matching portionand the second matching portionis different according to the fastening direction Rand the releasing direction R. When the second buckle elementrotates relative to the first buckle elementso that the ropeis wound around the columnalong the fastening direction R, the pushing surfacedoes not engage with the inclined surface. This will reduce the engagement strength between the first matching portionand the second matching portion, allowing the user to feel that the fastening force of the ropeis lighter and easier to tighten, thereby avoiding the feeling of gradually becoming heavier due to the increase in the tension of the rope. When the second buckle elementrotates relative to the first buckle elementto release the ropefrom the columnalong the releasing direction R, the stopping surfaceengages with the limiting surface. This will increase the engagement strength between the first matching portionand the second matching portion, so that the user feels that the loosening force of the ropeis heavier, thereby increasing the holding force of the rope. That is, the engagement strength in the fastening direction is smaller than the engagement strength in the releasing direction. Therefore, the engagement strength between the first matching portionand the second matching portioncan provide different operating feelings to the user.

In one embodiment, the first buckle elementand the second buckle elementare made of nylon, wherein the first buckle elementis integrally formed, and the second buckle elementis integrally formed, but the present disclosure is not limited to as such.

In one embodiment, as shown inand, the basemay be made of nylon, and the annular wall, the limiting portionsand the first matching portionmay be made of polyoxymethylene and are integrally formed. At this time, the basehas mounting openings, and the annular wallhas protrusions. The protrusionscan be snapped into the mounting openingsto connect the baseto the annular wall. The purpose of using polyoxymethylene is to prevent the problem of dimensional change after contact with water.

In another embodiment, as shown inand, the base, the annular walland the limiting portionsare made of nylon and are integrally formed, and the first matching portionis made of polyoxymethylene. At this time, the elastic portionsare connected to the connecting portionto form a cross shape. The connecting portionis locked in mounting openingsof the annular wall, so that the first matching portioncan be fixedly mounted in the annular wall.

In summary, the turntable adjustment buckle of the present disclosure is designed with elastic portions, tooth portions, and positioning grooves. The elastic portions are deformed by a force and generate resistance to rotation. Furthermore, the engagement strengths of the tooth portions and the positioning grooves in different rotation directions are different, which can provide users with different operating feelings to intuitively identify the direction of tightening or loosening the rope. In addition, the turntable adjustment buckle of the present disclosure has a low number of components, low manufacturing cost, and a wide range of applications.

Referring toand, a turntable adjustment buckleaccording to a second embodiment of the present disclosure includes a first buckle elementand a second buckle element, wherein the first buckle elementand the second buckle elementcan be assembled with each other, and the second buckle elementcan rotate relative to the first buckle element.

Please also refer to, the first buckle elementincludes a base, an annular wall, a first matching portion, an accommodating space, a first limiting portionand two first through holes.

The baseis roughly in the shape of a rectangular disk and has a shaft hole. The baseis used to fix or sew to an article.

The annular wallextends vertically outward from the base, and the cross section of the annular wallis annular. The shaft holeis approximately located at the center of the annular wall. The accommodating spaceis surrounded and defined by the baseand the annular wall. The first matching portionis disposed around the annular walland has a plurality of positioning grooves. Each positioning groovehas a pushing surfaceand a limiting surfaceadjacent to each other. The pushing surfaceand the limiting surfaceboth face the accommodating space. The area of the pushing surfaceis larger than the area of the limiting surface, so that the space surrounded by the pushing surfaceand the limiting surfacecan roughly have a triangular cross section. Furthermore, an inclination angle of the pushing surfacerelative to an inner surfaceof the annular wallis smaller than an inclination angle of the limiting surfacerelative to the inner surfaceof the annular wall. The first limiting portionis roughly an annular block and extends outward from the top edge of the annular wall. The two first through holesare formed through the annular walland correspond to each other.

In one embodiment, the number of the positioning groovesis 12. Moreover, the positioning groovesare annularly disposed on the inner side of the annular wallin a manner that the pushing surfaceis adjacent to the next adjacent limiting surface, but the present disclosure is not limited to as such.

Please also refer to, the second buckle elementincludes an operating portion, a column, a second matching portion, a second limiting portion, a second through holeand an assembly pillar.

The operating portionis roughly in the shape of a recessed disk, and the outer edge of the operating portionhas a plurality of concave grooves, which can provide friction when the user holds the operating portionto rotate it. The assembly pillaris disposed at the center of the operating portion, and the second limiting portionis disposed at the inner edge of the operating portionand extends inwardly. When the operating portionis disposed corresponding to the top edge of the annular wall, the second limiting portioncan be snapped into the first limiting portion. The columnis roughly cylindrical, and two ends of the columnhave a shaft portionand an assembly holerespectively. The assembly holeand the assembly pillarhave square cross-sections and can be assembled with each other, so that the columnis erected on the operating portionand can move together with the operating portion. The shaft portionis accommodated in the shaft hole, so that the second buckle elementcan rotate relative to the first buckle elementaround the shaft portionas an axis.

The second matching portionis annularly arranged on the side of the columnand matches with the first matching portion. The second matching portionhas three clawsreceived in the positioning grooves. Each clawhas a base end, a bending bodyand a buckle body. The base endis formed to extend outward from the column(e.g., along the radial direction of the column). The bending bodyis bent to connect the base endand is spaced apart from the column, and each bending bodyextends in the same rotation direction (counterclockwise inand clockwise in), that is, bends along the circumferential direction of the column. The buckle bodyis disposed at the end of the bending bodyand faces the positioning grooves. Each buckle bodyhas a roughly triangular cross section and has an inclined surfaceand a stopping surfaceadjacent to each other. The area of the inclined surfaceis larger than the area of the stopping surface, so that an inclination angle of the inclined surfacerelative to the bending bodyis smaller than an inclination angle of the stopping surfacerelative to the bending body. The second through holeis formed through the column, and the through direction thereof is parallel to the radial direction of the column.

Referring toand(is a top view after omitting the drawing of the operating portionand disposing the second matching portionin the base), when the first buckle elementand the second buckle elementare assembled with each other, the shaft portionis accommodated in the shaft hole, the assembly pillaris assembled in the assembly hole, the first limiting portionand the second limiting portionare locked with each other, the first matching portionand the second matching portionare matched with each other, and the buckle bodyis received in the positioning grooves, so that the pushing surfaceis correspondingly engaged with the inclined surface, and the limiting surfaceis correspondingly engaged with the stopping surface.
