Detailed Description

Complete technical specification and implementation details from the patent document.

The invention relates to the technical field of furniture, specifically an assembled sofa armrest structure.

Traditional sofa armrest structures are mostly integral. When sold and packaged, they are large in size, inconvenient for transportation and storage, and cannot be personalized according to user needs. Some prefabricated sofas on the market require customers to install them by themselves. The assembly is cumbersome and requires screws and professional tools to assemble. Therefore, it has certain limitations in use.

Therefore, it is necessary to develop an assembled sofa armrest structure to solve the above problems.

The purpose of the invention is to solve the problems mentioned in the background technology and provide an assembled sofa armrest structure.

Preferably, the splicing pieces are located at the top and bottom of the side plates; the splicing piece comprises a bottom plate and two assembly grooves symmetrically arranged, and the side plates are inserted into the assembly grooves; the assembly groove is composed of an inner plate and an outer plate, and the inner plate and the outer plate are arranged perpendicular to the bottom plate; the two assembly grooves are located on the same side of the bottom plate;

Preferably, the splicing pieces are located inside the two side plates; the splicing piece comprises inserting grooves and a U-shaped buckle; the inserting grooves are fixed on the inner side of the side plates by bolts, and the two opposite inserting grooves are connected by the U-shaped buckle, and both ends of the U-shaped buckle are embedded in the two inserting grooves.

Preferably, the splicing pieces are located inside the two side plates; the splicing piece comprises a U-shaped connecting piece and connecting bolts, and both ends of the connecting piece are provided with an embedding groove; the connecting bolts are fixedly connected to the inner side of the side plate, and the embedding grooves of the connecting piece are sleeved on the connecting bolts to form a stable connection structure.

Preferably, the width of the assembly groove is greater than the thickness of the side plate provided with the clamping groove.

Preferably, the number of connecting strips located at the front/rear ends of the two side plates shall not be less than two.

Preferably, the connecting strips are bandages, and the corresponding positions on the outside of the connecting strips and inside of the armrest cover are provided with matching Velcro straps.

Preferably, the inside of the armrest cover and the top of the cover are both provided with a flexible buffer layer.

The advantages of the invention compared with the existing technology are: the invention has a simple structure and is convenient to use. Through the combination of splicing body, armrest cover and cover, it is detachable, easy to transport and store. The sofa armrest can be assembled with insert-type assembly parts, which is fast and convenient. By matching assembled pieces of different sizes according to needs, the overall armrest width can be customized, which is flexible and can meet different needs. The design of the connecting strips between the side plates fixes the position of the side plates and enhances the stability of the structure. At the same time, the armrest covers at the front and rear ends are supported so that they are supported and not loose. In addition, there are flexible buffer layers inside the armrest cover and on the top of the cover to improve comfort.
