Description

Technical Field

[0001] This utility model relates to the field of sofa technology, specifically to a detachable sofa that is easy to pack. Background Technology

[0002] As a common household item, the sofa is an indispensable seating piece in a family's home life. However, the backrest and main seat of sofas on the market are usually molded as one piece, and cannot be disassembled. Sofas are usually large and heavy, so moving and packing sofas is inconvenient and increases transportation costs.

[0003] Patent document CN216059924U discloses a sofa with detachable legs, relating to the field of furniture technology. It includes a sofa body, support legs, and a connecting mechanism. The sofa body includes a seat and a backrest. Support legs are installed at the four corners of the bottom of the seat, and these support legs are connected to the seat via the connecting mechanism. The connecting mechanism includes a mounting box, a fixing groove, and a fixing block. The mounting box is installed at each of the four corners of the bottom of the seat, and the bottom of the mounting box has a fixing groove. The top of each support leg has a fixing block that matches the fixing groove. One end of the mounting box has a locking mechanism that fixes the position of the fixing block. This invention allows the support legs to be detached through the cooperation of the fixing block and the fixing groove. This quick detachment of the support legs prevents damage caused by collisions during transport. Although this sofa features a detachable design, the detachment is limited to the body and the support legs; the sofa itself cannot be disassembled. Therefore, it still occupies considerable space during transportation and cannot achieve a smaller overall size. Utility Model Content
