Description

Technical Field

[0001] This utility model belongs to the technical field of sofas and accessories, and in particular relates to a quick assembly structure for sofa frames. Background Technology

[0002] Sofas are one of the most common pieces of furniture in homes, typically used in living rooms, rest areas, and other spaces to provide a comfortable sitting or lying experience. Sofas can be mainly categorized by style into New Chinese style sofas, Scandinavian style sofas, industrial style sofas, and so on. New Chinese style sofas are characterized by their simple shapes, smooth lines, mixed materials, a balance of strength and softness, calm colors, and accent colors. Scandinavian style sofas, on the other hand, are characterized by their smooth curves, modular design, natural materials, and practical functions. Sofas are mainly composed of fabric, seat cushions, armrests, backrests, frames, and spring systems. To facilitate the splicing of sofa frames, quick-assembly structures are often used.

[0003] A modular sofa is disclosed in the existing patent announcement document CN222787384U, including a sofa mechanism and a clamping mechanism. The clamping mechanism is fixedly connected to the sofa mechanism. The clamping mechanism includes a power box. A rotary motor is fixedly connected to the bottom of the inner wall of the power box. A drive wheel is fixedly connected to the output end of the rotary motor. A positive and negative threaded rod is movably connected to the back of the inner wall of the power box through a rotating shaft. The other end of the positive and negative threaded rod is movably connected to the inner wall of the power box through a rotating shaft. A driven wheel is sleeved on the surface of the positive and negative threaded rod.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The modular sofa described above uses a clamping mechanism and a telescopic mechanism to assemble adjacent frame components. However, during use, the power box in the clamping mechanism is fixed at the bottom of the frame component. Since the position of the power box is fixed, it is not convenient to adjust the position of the clamping mechanism according to the position of the telescopic mechanism, and it is not convenient to position the clamping mechanism and the telescopic mechanism, which makes it inconvenient to quickly assemble the frame components.

[0006] 2. The modular sofa described above uses a clamping mechanism and a telescopic mechanism to splice adjacent frame components. However, during use, the installation position and direction of the clamping mechanism and the telescopic mechanism on the frame components are fixed, making it inconvenient to splice two frame components in multiple directions.

[0007] To address these issues, we provide a quick-assembly structure for sofa frames. Utility Model Content

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a quick-assembly structure for a sofa frame, including a sofa frame body 1, a clamping member 2, and a connecting member 3.
