Description

Sofa component

Technical Field

The application relates to the field of sofa structures, in particular to a sofa component.

Background

The traditional sofa components (such as structures of a sofa backrest, armrests, seat frames and the like) mainly adopt a wood frame structure, so that the preparation cost of the sofa is reduced, and the traditional sofa components are manufactured by adopting a blow molding process.

Although the sofa component adopts the blow molding process, the sofa cover and the blow molded sofa frame are connected by adopting a gun nail or a zipper, when the sofa cover is connected to the outside of the sofa component or the sofa main body by adopting the gun nail, the gun nail has the problems of low working efficiency and inaccurate position; the sofa is fully covered outside the sofa component in a zipper mode, and the sofa is convenient to install, but has the problem of easy loosening. In order to improve the convenience of installing the sofa cover on the sofa component and not easy to loosen, the fastening strip is added on the sofa component, so that the sofa cover is fastened with the fastening strip, and the sofa cover can be conveniently connected with the sofa frame.

Although the buckle strip can help the sofa cover to be quickly connected to the sofa frame, the buckle strip is connected to the sofa frame firstly to realize the quick connection of the sofa cover and the sofa frame. The need to add an additional step to connect the straps to the sofa frame, both manually and mechanically, also increases the overall cost of the sofa.

With respect to the above related art, the inventor believes that there is still a lack of a solution in the prior art that can combine the sofa component and the buckle strap structure of the blow molding process.
