[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a sofa with a detachable structure includes a back panel frame 1, a back panel cushion 2 wrapped around the outside of the back panel frame 1, the lower part of the front panel of the back panel frame 1 is not included by the back panel cushion 2, a docking mechanism for connecting with the seat frame 3 is installed on the lower front panel of the back panel frame 1, a seat cushion 4 is placed on the top of the seat frame 3, one end of the docking mechanism extends from the back end of the seat frame 3 into the interior of the seat frame 3, and a docking slot 6 for docking insertion is opened at one end of the seat frame 3.

[0018] In this embodiment: When moving the sofa, the back panel frame 1 and the seat frame 3 can be separated by rotating the docking mechanism. After separation, they can be moved separately, thus avoiding the problem of the sofa being too heavy to move. The step-by-step movement also makes it easier for the sofa to enter the room through the door, avoiding the problem of the sofa being too large and easily getting stuck.

[0019] After both parts of the sofa are installed inside the room, the back panel frame 1 and the seat frame 3 are connected and installed using a docking mechanism.

[0020] Please refer to this carefully. Figure 2 and Figure 3 The docking mechanism is fixedly installed on the support base 7 at the lower front end of the back panel frame 1. Rotating arms 9 are rotatably installed on the inner side of the two support bases 7. The end of the rotating arm 9 away from the support base 7 is integrally formed with a pressure inclined surface 13. Multiple pressure inclined surfaces 13 are coaxially connected by a synchronous shaft 10. One end of the synchronous shaft 10 extends to the outside of the seat frame 3. A rotating handle 5 is fixedly installed on the end of the synchronous shaft 10 located outside the seat frame 3. The docking mechanism also includes a fixed plate 11 integrally formed on the outer wall of the synchronous shaft 10. A support plate 15 integrally formed at the lower front end of the back panel cushion 2 extends through the docking slot 6 into the interior of the seat frame 3. A torsion spring 12 is fixedly connected between one side of the synchronous shaft 10 and the support plate 15. The torsion spring 12 is sleeved on the outer periphery of the synchronous shaft 10. Horizontal grooves 14 for sliding of the synchronous shaft 10 are opened on the back panel frame 1 and the seat frame 3.

[0021] In this embodiment: when the back panel frame 1 and the seat frame 3 are docked, the docking mechanism, the support plate 15 and the docking slot 6 are aligned. At this time, the synchronous shaft 10 is aligned with the horizontal slot 14. Then, the seat frame 3 is pushed to move towards the back panel frame 1. At this time, the rotating arm 9 gradually approaches the hook column 8 until the hook column 8 contacts the pressure inclined surface 13. At this time, the rotating arm 9 under pressure rotates downward. At this time, the fixed plate 11 rotates synchronously with the synchronous shaft 10. Therefore, the torsion spring 12 connected to the fixed plate 11 rotates. The end of the torsion spring 12 connected to the support plate 15 remains stationary. The torsion spring 12 is twisted. Multiple rotating arms 9 rotate synchronously through the synchronous shaft 10 until the hook column 8 and the pressure inclined surface 13 are misaligned. At this time, the torsion spring 12 resets. The reset torsion spring 12 drives the fixed plate 11 to rotate and reset. The fixed plate 11 drives the synchronous shaft 10 to rotate and reset. The synchronous shaft 10 drives multiple rotating arms 9 to rotate and reset upward. Thus, hooking with the hook column 8 is achieved, and docking assembly is completed.

[0022] During disassembly, by rotating the handle 5, the handle 5 drives multiple rotating arms 9 to rotate downwards via the synchronous shaft 10, thereby separating the docking mechanism from the hook column 8, and the sofa can be disassembled.

[0023] Please refer to this carefully. Figure 3A hooking column 8 is fixedly installed on the inner side of the seat frame 3, and an arc-shaped groove is formed on the top of the rotating arm 9 to hook the hooking column 8.

[0024] In this embodiment: when the rotating arm 9 rotates upward to reset, the arc-shaped groove engages with the hook column 8, and at this time the engagement mechanism completes the assembly of the sofa.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
