[0002] A modular sofa is a piece of home furniture composed of multiple independent sofa units. It can be freely spliced and matched according to different spaces and needs, making the home space more flexible and changeable.
[0003] When existing small and medium-sized modular sofas are assembled and combined, they are assembled and clamped using the clamps at the bottom of the sofa. Since the sofa is close to the ground, the sofa usually needs to be lifted to open the clamps for assembly and disassembly, and it is difficult to disassemble.
[0004] Therefore, it is very necessary to design a modular sofa that is easy to operate. Utility Model Content

[0006] The technical implementation scheme of the utility model is: a combined sofa connection structure, including a sofa monomer, and also includes a rotating seat, a clamping block, a clamping ring, a pull rod and a limiting rod. A clamping groove is opened on the side of the sofa monomer, the rotating seat is rotatably connected in the clamping groove, the radial side of the rotating seat is fixed with a clamping block, the rotating seat can be fixed in the clamping groove through the clamping block, the axial side of the rotating seat is provided with a clamping ring, the end of the pull rod is provided with a limiting rod, the pull rod is slidably connected to another sofa monomer, and the pull rod limits and fixes the clamping ring through the limiting rod, and then fixes the rotating seat.
[0007] As a further preferred embodiment, it also includes a first return spring, a slider and a rotating wheel. The first return spring is arranged in the slot, one end of the first return spring is connected to the slider, and the other end is connected to the inner wall of the slot. The rotating wheel is rotatably connected in the slider, and the rotating wheel is fixedly connected to the rotating seat.
[0008] As a further preferred solution, a slide groove is provided on the inner wall of the card slot, and the card block can slide in the slide groove.

[0021] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] Embodiment: A modular sofa connection structure, such as Figure 1-Figure 5As shown, it includes a sofa monomer 1, a rotating seat 6, a clamping block 8, a snap ring 9, a pull rod 10 and a limiting rod 11. A protective pad 15 is arranged on the side of the sofa monomer 1. A clamping slot 2 is opened at the lower right side of the sofa monomer 1. The rotating seat 6 is rotatably connected in the clamping slot 2. The clamping block 8 is fixed to the radial side of the rotating seat 6. The rotating seat 6 can be fixed in the clamping slot 2 through the clamping block 8. Specifically, a slide groove 5 is opened on the inner wall of the clamping slot 2. The clamping block 8 can slide in the slide groove 5. A snap ring 9 is arranged on the axial side of the rotating seat 6. A limiting rod 11 is arranged at the end of the pull rod 10. One end of the second return spring 12 is connected to the limiting rod 11, and the other end is connected to the sofa monomer 1. The pull rod 10 is slidably connected to another sofa monomer 1, and the pull rod 10 limits and fixes the snap ring 9 through the limiting rod 11, and then fixes the rotating seat 6.
[0023] like Figure 3 As shown, it also includes a first return spring 3, a slider 4 and a rotating wheel 7. The first return spring 3 is arranged in the slot 2. One end of the first return spring 3 is connected to the slider 4, and the other end is connected to the inner wall of the slot 2. The rotating wheel 7 is rotatably connected in the slider 4, and the rotating wheel 7 is fixedly connected to the rotating seat 6.
[0024] like Figure 5 As shown, a pull rope 13 is also included, and the clamp ring 9 is connected to the pull rope 13.
[0025] like Figure 2 As shown, an anti-skid pad 14 is also included, and the pull rod 10 is sleeved with the anti-skid pad 14.
[0026] like Figure 1-Figure 5 As shown, according to the above-mentioned modular sofa connection structure, a modular sofa is proposed, which is composed of two sofa monomers 1 connected at the sides.
[0027] Operation method: The modular sofa is composed of a sofa monomer 1. When the sofa monomers 1 need to be combined, the rotating seat 6 can be pulled out to the left by the pull rope 13. At this time, the block 8 slides in the slide groove 5, and the rotating seat 6 moves to the left end limit position of the slide groove 5. The first return spring 3 is in a stretched state, and then the rotating seat 6 is driven to rotate by the snap ring 9, and the rotating seat 6 is rotated forward 90 degrees. The inner wall of the slot 2 is provided with a recess that can be engaged with the block 8, so that the rotating seat 6 can be fixed. At this time, the snap ring 9 is in a vertical state, and then another sofa monomer 1 is moved to the left side of the sofa monomer 1 and fitted, and the pull rod 10 is pulled forward and the limit rod 11 is inserted into the snap ring 9. The limit rod 11 remains fixed under the action of the second return spring 12 and does not slide forward to reset. At this time, the limit rod 11 and the snap ring 9 are in a fixed state, thereby fixing the rotating seat 6, so that the two sofa monomers 1 are in a mutually fixed state, so that the effect of the modular sofa is achieved. When the modular sofa needs to be extended, the above actions can be repeated to adjust the length of the modular sofa.
[0028] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
