Description

Technical Field

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

[0002] With the development of the logistics industry, people's daily necessities are now trending towards simplicity and convenience. To adapt to fast-paced lifestyles and facilitate transportation, existing sofas are typically modular. However, traditional modular sofas rely on screws or glue to fix the components, making disassembly and assembly cumbersome and prone to damaging parts. Furthermore, current modular sofas are usually fixed structures or rely on screws for manual adjustment of the backrest angle, failing to offer both quick locking and automatic backrest angle adjustment.

[0003] Therefore, there is an urgent need for a modular sofa that is easy to assemble and can automatically flip its backrest. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a detachable sofa that can automatically flip its backrest through simple assembly.

[0007] Furthermore, the first latch includes a male latch connected to the base and a female latch correspondingly installed at the bottom of the backrest. The female latch is provided with a first guide rail, which is vertically arranged. The female latch is provided with a first limiting protrusion, and the male latch is provided with a first locking groove that matches the first limiting protrusion. The male latch can slide along the first guide rail and engage with the female latch through the first limiting protrusion and the first locking groove.

[0008] Furthermore, the male buckle is hinged to the base, and the backrest is hinged to the base via the male buckle.

[0009] Furthermore, the female buckle is provided with an elastic arm, and the first limiting protrusion is provided at the end of the elastic arm and faces the inside of the first guide rail.

[0010] Furthermore, a leg support plate is hinged to the end of the base away from the backrest, and the control system can control the flipping angle of the leg support plate.

[0011] Furthermore, the base is provided in multiple parts, and two adjacent bases are detachably connected by a second latch.

[0012] Preferably, the second latch is provided in multiple equally spaced positions.

[0013] Preferably, each of the bases is equipped with a control system, and each base is hinged to a backrest.

[0014] Preferably, the second latch includes a second guide rail, a second slot, and a second limiting protrusion corresponding to the second slot. The second slot is located at the end of the second guide rail, and the second limiting protrusion can slide along the second guide rail. The second limiting protrusion is located on the side of a base, and the second guide rail and the second slot are correspondingly located on the side of another adjacent base. The second guide rail is an inclined rail.

[0015] Preferably, two adjacent bases are also fixedly connected by bolts.

[0016] Preferably, the male buckle is provided on the left and right sides of each base, and the female buckle is provided on the left and right sides of the bottom of each backrest.

[0017] Furthermore, the base is provided with control buttons on its side, which are electrically connected to the control system. The backrest and leg rest can be adjusted by using the control buttons.

[0018] Furthermore, the detachable sofa also includes an electrical system, which includes a power cord and a power supply cord. The power cord is electrically connected to the control system, and the power cord is electrically connected to the power supply cord.
