Description

Technical Field

[0001] The utility model relates to the technical field of sofa assembly, in particular to an assembled multi-person sofa frame structure. Background Art

[0002] In order to ensure that the two sofas are physically more firmly connected together to prevent shaking or shifting during use, especially in homes with children or pets, a stable sofa connection can prevent them from accidentally pushing the sofa, resulting in a large gap between them and getting stuck in the sofa gap. Therefore, two assembled sofas in the home are generally connected by hooks;

[0003] However, in the existing hook connection method, the hooks are all located at the bottom of the sofa. If two sofas want to be connected, the user has to reach deep into the bottom of the sofa to hang the hooks. Later, when cleaning the gaps in the sofa, for example, the user has to use this method to disconnect the hooks. This operation is not only inconvenient because the hooks cannot be seen, but also dirty the hands. Utility Model Content

[0004] The purpose of the present invention is to solve the shortcomings of the existing technology and to propose an assembled multi-person sofa frame structure. Compared with the existing technology, this structure is convenient for connecting two sofas, ensures the overall stability during use, and the subsequent method of releasing the limit is also relatively simple.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multi-person sofa frame structure is provided, comprising two sofa bodies, with armrests installed on the upper ends of the opposite sides of the two sofa bodies; a connecting mechanism, wherein the connecting mechanism is used to connect the two sofa bodies, the connecting mechanism comprising a slide groove provided on the right side of the left sofa body, a bidirectional threaded rod being rotatably connected between the front and rear inner walls of the slide groove, both threaded ends of the bidirectional threaded rod being threadedly connected to sliders, the right sides of the two sliders being fixedly connected to rectangular connecting blocks, the opposite sides of the two rectangular connecting blocks being fixedly connected to plug blocks, two rectangular openings being symmetrically provided on the left side of the sofa body, and limiting openings being provided on the opposite side walls of the two rectangular openings.

[0007] Preferably, the two sliding blocks are both slidably connected to the inner wall of the sliding groove.

[0008] Preferably, each of the rectangular openings cooperates with a corresponding rectangular connecting block, and each of the limiting openings cooperates with a corresponding inserting block.

[0009] Preferably, cushion frames are installed on the rear sides of the two sofa bodies.

[0010] Preferably, a plurality of moving wheels are installed at the lower ends of the two sofa bodies.

[0011] Preferably, a columnar groove is provided on the front side wall of the sofa body on the left side, and the front end of the bidirectional threaded rod extends into the columnar groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The design of movable wheels greatly improves the overall mobility of the sofa. Users can easily adjust the position of the sofa without any effort in carrying it, meeting the demand for flexible furniture layout in modern home life. In addition, an innovative connection mechanism is adopted, that is, a two-way threaded rod is used to drive the movement of the slider and the plug to achieve the rapid connection and separation of the sofa body. Compared with the traditional hook connection method, the operation process is simpler and faster, which greatly saves users' time and energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 3 , an assembled multi-person sofa frame structure, comprising two sofa bodies 1, armrests 2 are installed on the upper ends of the opposite sides of the two sofa bodies 1, and cushion frames 4 are installed on the rear sides of the two sofa bodies 1;

[0020] Furthermore, a plurality of moving wheels 3 are installed at the lower ends of the two sofa bodies 1;

[0021] Furthermore, it also includes a connecting mechanism, which is connected to two sofa bodies 1. The connecting mechanism includes a slide 5 opened on the right side of the left sofa body 1, and a bidirectional threaded rod 10 is rotatably connected between the front and rear inner walls of the slide 5. The two threaded ends of the bidirectional threaded rod 10 have opposite thread directions. The two threaded ends of the bidirectional threaded rod 10 are threadedly connected to a slider 6. The two sliders 6 are slidably connected to the inner wall of the slide 5. The right sides of the two sliders 6 are fixedly connected to a rectangular connecting block 7, and the opposite sides of the two rectangular connecting blocks 7 are fixedly connected to an insert block 8. Two rectangular openings 11 are symmetrically opened on the left side of the sofa body 1, and a limited opening 12 is opened on the opposite side walls of the two rectangular openings 11. Each rectangular opening 11 cooperates with a corresponding rectangular connecting block 7, and each limited opening 12 cooperates with a corresponding insert block 8.

[0022] Furthermore, a columnar groove 9 is provided on the front side wall of the sofa body 1 on the left side, and the front end of the bidirectional threaded rod 10 extends into the columnar groove 9 .

[0023] In the present invention, when it is used, the whole body can be conveniently moved by the moving wheel 3. If two sofa bodies 1 need to be connected, it is only necessary to move the two sofa bodies 1 close together, and then let the two rectangular connecting blocks 7 enter the corresponding rectangular openings 11. Then, the two-way threaded rod 10 is rotated from the columnar groove 9 to drive the two sliders 6 to move away from each other, thereby driving the inserting blocks 8 to move away from each other and enter the corresponding limiting openings 12 to complete the limiting. Subsequently, it is only necessary to perform the operation in the reverse direction to release the limiting. Compared with the hook connection in the prior art, this connection method is simpler and more convenient, and the stability after connection is also stronger.
