Back-Pedal Hack Integrated Machine Convenient for Angle Adjustment

The present invention relates to the field of back-pedal Hack integrated machine, in particular to a back-pedal Hack integrated machine convenient for angle adjustment.

The back-pedal Hack integrated machine can allow the trainer to perform the training of back pedal and Huck squat at the same time through one equipment, which is of great significance for reducing the floor space of gym equipment. The traditional back-pedal Hack integrated machine can only train leg and hip muscles at a 45-degree angle, and trainers with different body shapes and heights cannot make appropriate adjustments according to their own needs, so the training method is too simple. In addition, through proper angle adjustment, different muscle groups of the body can also be exercised.

Therefore, it is necessary to develop a new type of back-pedal Hack integrated machine, which can adjust the angle properly according to the needs of trainers, and also can exercise different muscle groups of the body through appropriate angle adjustment.

The present invention provides an back-pedal Hack integrated machine convenient for angle adjustment, which comprises an underframe, wherein the underframeis provided with a rotatable first frame bodyand a rotatable second frame body; the long side of the second frame bodyis provided with a freely slidable slider, which is used for setting a required counterweight; the angle adjustment between the first frame bodyand the underframeis realized through a first angle adjustment mechanism; and the angle adjustment between the second frame bodyand the underframeis realized through a second angle adjustment mechanism.

Wherein, the first frame bodyforms a rotatable structure with the underframethrough a first pivot a, and the second frame bodyforms a rotatable structure with the underframethrough a second pivot b, and bearings are arranged in both the first pivot a and the second pivot b;

In this embodiment, the first pivot a is arranged between the first frame bodyand the underframe, so that the first frame bodycan be turned left and right, thereby adjusting the inclination angle of the first frame bodyto meet the needs of different users. By arranging the second pivot b between the second frame bodyand the underframe, the second frame bodycan also be turned left and right, so as to adjust the inclination angle of the second frame bodyto meet the needs of different users.

Therefore, through the first frame bodyand the second frame body, which can adjust the angle, trainers with different body shapes and heights can adjust the inclination angle of the back-pedal Hack machine according to their own needs, so that the training methods are more diversified, and different muscle groups of the body can also be exercised through proper angle adjustment.

The force bearing surface of the first frame bodyis provided with a detachable pedal and a backrest plate, and the functions of the integrated machine are switched by exchanging the pedal and the backrest plate;

In order to increase the user's comfort and provide lumbar support during back pedal training, a backrest plate (not shown in the attached figure) can be installed on the first frame body. The backrest can support the waist of the user, ensuring that the user can get stable support during the training process, thus improving the training effect.

When doing sitting-Hack squat training, a pedal (not shown in the attached figure) is further installed on the first frame body, so that the user can easily put his feet on the pedal, thus ensuring the accuracy and stability of the squat action.

Through these two simple and practical accessory designs, the back-pedal Hack integrated machine has achieved multi-functional training effect, and both back-pedal training and sitting Hack squat training can be easily completed on this integrated machine, which not only improves the utilization rate of the back-pedal Hack integrated machine, but also greatly saves the use space, and realizes the efficient design concept of multi-purpose of one machine.

In this embodiment, the first angle adjustment mechanism includes a swing rodpivotally connected to the bottom of the first frame body, and a locking memberfixed on the underframe. The free end of the swing rodis set as a clamping part, and a plurality of clamping groovesare concavely formed in the locking member, and the clamping groovesare arranged corresponding to the clamping part.

The swing rodcan swing flexibly from left to right, and the clamping partis in the form of a cross bar. When the first frame bodyis adjusted to the required angle, the user only needs to rotate the swing rodand insert the clamping partinto the corresponding clamping grooveaccurately. Once the clamping partis successfully inserted into the clamping groove, a stable clamping relationship will be formed between the clamping part and the clamping groove, thus ensuring that the first frame bodycan maintain a stable inclination angle during training. This structure not only makes the angle adjustment of the first frame bodyeasier and faster, but also effectively fixes the inclination angle of the first frame bodythrough the support of the swinging rod, thus improving the stability and safety of training.

In other embodiments, the first angle adjustment mechanism can also adopt a hydraulic adjustment mechanism or a mechanical transmission system such as a lever, a gear or a worm gear to realize angle adjustment.

In other embodiments, in order to further improve the user's experience, rubber pads can be bonded to the surfaces of the clamping grooveand the clamping part, which can play the role of buffering and damping, effectively reduce the vibration and impact of the equipment during the angle adjustment, and also reduce the noise, thus creating a quieter and more comfortable training environment for the user.

In this embodiment, a damping hinge or hydraulic support rodis arranged between the second frame bodyand the connecting frame, and the second adjustment mechanism includes the connecting framefixedly connected with the underframe, and a telescopic memberarranged between the connecting frameand the second frame body. The telescopic memberincludes a sleeveand a telescopic tube, and the sleeveis rotatably connected to the connecting frame; one end of the telescopic tubeis rotatably connected to the second frame body, and the other end of the telescopic tubepasses through the sleeve; and the telescopic tubeis connected with the sleevein a sliding manner, and the sleeveis provided with a locking memberfor locking the telescopic tubein the sleeve;

by arranging the damping hinge or the hydraulic support rodbetween the second frame bodyand the connecting frame, the damping hinge or the hydraulic support rodcan play a certain supporting role for the second frame bodywhen the second frame bodyis overturned, so that the overturn of the second frame bodyis more labor-saving and smooth.

When the damping hinge is used, the second frame bodywill be subjected to a certain damping force when overturning, which can balance the gravity or inertia force generated in the overturning process to a certain extent, making the overturning action more stable. At the same time, the damping force of the damping hinge can be adjusted as required to adapt to the use habits and strength of different trainers.

When the hydraulic support rodis used, the incompressibility of liquid and the principle of fluid mechanics are used to provide a stable supporting force for the overturning of the second frame body. When the second frame bodybegins to overturn, the hydraulic support rodcan generate supporting force through the internal hydraulic cylinder or piston mechanism to help users easily complete the overturning action. Moreover, the advantages of the hydraulic support rodare that its supporting force can be adjusted as required, and it has a long service life and stability.

In other embodiments, any other components or mechanisms that are beneficial to the overturning of the second frame bodycan be adopted between the second frame bodyand the connecting frame.

In this embodiment, when the second frame bodyis turned left and right, the telescopic tubecan slide left and right in the sleeve, and when the second frame bodyis turned to the required angle, the locking membercan be used to fix the telescopic tubeand the sleeve, thus fixing the second frame bodyto the required angle.

In one embodiment of the locking member, the locking memberis a pin, and the pin penetrates into the sleeve, and the surface of the telescopic tubefacing the locking memberis uniformly provided with a plurality of jacks, and the pin is inserted into one of the jacks;

the pin can be inserted into the sleeve, and when the pin is pulled out from the sleeve, the telescopic tubecan slide in the sleeve; when the telescopic tubeand the sleeveare fixed, the pin is inserted into the sleeveand inserted into the corresponding jack, so that the telescopic tubeand the sleevecan be fixed.

Through this embodiment, when the angle of the second frame bodyis adjusted, since the positions of the jacks are preset, corresponding to different inclination angles, the second frame bodywill be fixed at a specific inclination angle every time the bolt is inserted into a different jack. This design enables the user to quickly adjust to the required angle and keep it stable without complicated adjustment and fixing operations.

Moreover, this embodiment not only improves the ease of use and operation efficiency of the equipment, but also ensures the stability and safety of the second frame bodyduring training. Moreover, this mode has certain durability and reliability, and can meet the needs of long-term use.

In one embodiment of the locking member, the locking memberis a bolt, which is screwed with the sleeve, and one end of the bolt penetrates into the sleeveand closely adheres to the surface of the telescopic tube.

When it is necessary to adjust the angle of the second frame body, the user can slide the telescopic tubeto find the required inclination angle. Then, the user can lock this angle by screwing the bolt. When the bolt rotates in the direction of the telescopic tube, its head or end will gradually approach the surface of the telescopic tube. With the further rotation of the bolt, the head or end of the bolt will be closely attached to the surface of the telescopic tubeand exert a certain pressure. This pressure and friction work together to fix the telescopic tubeat a specific position in the sleeve. Since the rotation of the bolt and the applied pressure are controllable, the user can adjust the strength of the bolt as needed to ensure that the telescopic tubeis firmly fixed.

Through this locking mode, the locked angle of the second frame bodyis linear, and this linear angle adjustment mode enables users to easily adjust the second frame bodyto the required precise angle, and satisfactory results can be obtained regardless of small angle fine adjustment or large adjustment. At the same time, the second frame bodycan adapt to more different training needs and personal preferences, which improves the flexibility and applicability of the equipment.

In other embodiments of the locking member(not shown in the attached drawings), it can also be in the form of clamping, clamping spring, sliding clamping block, etc.

In other embodiments of the telescopic member(not shown in the attached drawings), the telescopic membercan also be a hydraulic cylinder, an electric cylinder, etc. with active telescopic function, so that the inclination angle of the second frame bodycan be automatically adjusted, making the angle adjustment of the second frame bodymore convenient.
