Description

Technical Field

[0001] The utility model relates to the technical field of sofas, in particular to a multifunctional spliced ​​sponge sofa. Background Art

[0002] Sofas have become a necessary piece of furniture for many families, and they are also used in some specific places, such as conference halls, exchanges, etc. At present, whether it is a wooden sofa, a cloth sofa or a leather sofa, its structure is generally fixed. During the transportation and assembly process, it is inconvenient to transport due to its large size. It is also often encountered that the sofa is too large to pass through a door of normal specifications, resulting in difficulty in transportation.

[0003] When optimizing the existing multifunctional splicing sponge sofa equipment, most of the effects of the device on the splicing of the sofa are reflected. For example, the Chinese utility model patent with publication number CN202322139912.4 discloses a "Splicing Sofa". The utility model patent sets a flexible support mechanism, and the legs are symmetrically arranged at the bottom of the left armrest, the right armrest and the corner support frame, the right front plate is arranged between the right armrest and the lower side of the corner support frame, and the left front plate is arranged between the left armrest and the lower side of the corner support frame. By setting a support frame and splitting the support frame into left armrest, right armrest, corner support frame, legs, right front plate, left front plate, rear plate, left rear frame, right rear frame, seat frame and other components, they can be uniformly disassembled and packed during transportation, saving transportation space, reducing transportation risks, and facilitating assembly by users.

[0004] Although the above method has certain advantages in terms of improvement, it still has certain disadvantages: if the movable board cannot be extended and retracted, when the sofa does not need to be spliced, the protruding movable blocks may cause children to be bumped.
