[0002] At present, most of the sofas sold on the market are of an integrated type. Although this design meets people's requirements for sofas to a certain extent, there are also some deficiencies. For example, for an integrated sofa, when it comes to disassembly and washing, it requires more effort and is prone to incomplete cleaning. In addition, an integrated sofa is difficult to transport, has a high transportation cost, a complex production and processing process, and a high production cost. At the same time, this type of sofa cannot be flexibly combined and cannot meet people's diverse needs.

[0003] Of course, there are also some sofas assembled by fixedly connecting with connecting pieces and screws. This type of sofa solves the problem of difficult transportation of the sofa, but its assembly process is rather cumbersome. It is necessary to turn the whole sofa over for reverse assembly and external tools such as screwdrivers are needed to achieve the assembly, which is extremely inconvenient.

[0004] Therefore, a new solution is needed to solve this problem. Summary of the Utility Model

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] A modularly assembled sofa, as Figures 1-4 shown, includes two groups of sofa modules 1 and a backrest 2. A connection component is provided on the side wall of the sofa module 1. The connection component includes a groove 3 provided on the side wall of the sofa module 1 and a support block 4 slidably connected to the inner wall of the groove 3. One end of the support block 4 extending out of the groove 3 is slidably connected to a moving block 5. A through groove for the support block 4 to extend out is provided on the moving block 5. A fixing device for limiting the moving block 5 is provided on the side wall of the sofa module 1. A connecting rod 6 slidably connected to it is provided on the side wall of the moving block 5. One end of the connecting rod 6 away from the moving block 5 is fixedly connected to a mounting block 7. An insert block 8 is fixedly connected to the side wall of the sofa module 1. There are two groups of insert blocks 8 arranged along the vertical direction. An insert hole 9 for the insert block 8 to be inserted into is provided on the mounting block 7.

[0024] The fixing device includes an electric push rod 10 fixedly connected to the side wall of the sofa module 1. The output end of the electric push rod 10 is fixedly connected with a vertical plate 11. On one side of the vertical plate 11 close to the moving block 5, two vertically arranged limiting pieces 12 are fixedly connected. The positions of the two limiting pieces 12 on both sides correspond to the positions of the two groups of inserting blocks 8. The moving block 5 and the supporting block 4 are respectively provided with a first limiting hole 13 and a second limiting hole 14 for the limiting pieces 12 to insert. When the inserting block 8 is inserted into the inserting hole 9, the positions of the first limiting hole 13 and the second limiting hole 14 correspond to each other.

[0025] A connecting groove 15 for the connecting rod 6 to insert is formed on the side wall of the moving block 5.

[0026] A clamping block 16 is fixedly connected to the side wall of the connecting rod 6. A clamping groove 17 for the clamping block 16 to insert and move is provided on the inner wall of the connecting groove 15. During the process of the connecting rod 6 moving along the connecting groove 15, the clamping block 16 will insert into the clamping groove 17 and move, preventing the connecting rod 6 from falling off from the connecting groove 15 and limiting the connecting rod 6.

[0027] A convex block 18 is fixedly connected to the side wall of the supporting block 4. A concave groove 19 for the convex block 18 to insert and move is provided on the inner wall of the groove 3. During the process of the supporting block 4 moving along the groove 3, the convex block 18 will insert into the concave groove 19 and move, making the supporting block 4 more stable during the moving process.

[0028] A limiting block 20 is fixedly connected to the inner wall of the through groove. A limiting groove 21 for the limiting block 20 to insert and move is provided on the outer wall of the supporting block 4. During the process of the moving block 5 sleeving outside the supporting block 4 and moving, the limiting block 20 will always insert into the limiting groove 21 and move, making the moving block 5 more stable during the moving process and preventing the moving block 5 from falling off from the supporting block 4.

[0029] Working principle: When two sofa modules 1 need to be connected together, first place the sofa modules 1 on both sides close to each other. Then move the support block 4 on one side, so that it drives the moving block 5 and the mounting block 7 to correspond to one set of insertion blocks 8 on the other sofa module 1. Then move them outward away from the sofa module 1. Then pull out the connecting rod 6 from the connecting groove 15, so that the jack 9 on the mounting block 7 comes to a position corresponding to the insertion block 8 on the adjacent sofa module 1. Then move the moving block 5 along the support block 4 towards the side close to the sofa module 1, so that the mounting block 7 approaches the insertion block 8 and the insertion block 8 is inserted into the jack 9 on the mounting block 7. At this time, the limiting hole one 13 and the limiting hole two 14 on the moving block 5 and the support block 4 are in corresponding positions. Extend the electric push rod 10, so that the vertical plate 11 drives the limiting piece 12 to be inserted into the limiting hole one 13 and the limiting hole two 14. In this way, the moving block 5 can stay in the current position to keep the insertion block 8 and the jack 9 connected, and the two sofa modules 1 on both sides are stably connected together. The support block 4 on the other sofa module 1 can move along the groove 3 to correspond to the height of the other set of insertion blocks 8, and then connect the mounting block 7 and the jack 9 together in the same way. In this way, through the connection of the two sets of insertion blocks 8 and jacks 9, the connection between the two sofa modules 1 on both sides can be made more stable;

[0030] At the same time, such a connection component can be set on the left and right sides of a sofa module 1 at the same time, so that both the left and right sides of the sofa module 1 can be connected to the adjacent sofa module 1 in the same way in turn, realizing the assembly operation of multiple sofa modules 1;

[0031] When the sofa modules 1 on both sides need to be disassembled, first shorten the electric push rod 10, so that the limiting piece 12 is pulled out from the limiting hole one 13 and the limiting hole two 14. Then move the moving block 5 outward, so that the insertion block 8 and the jack 9 are separated, and the two sofa modules 1 on both sides can be disassembled. During the whole process, there is no need to flip the sofa module 1, nor to use external tools, and the operation is convenient.

[0032] Furthermore, after disassembling, the connecting rod 6 can also be inserted into the connecting groove 15, so that the mounting block 7 retracts to its original position, that is, the position corresponding to the insertion block 8 on the same sofa module 1. Then move the moving block 5 in the opposite direction again, so that the insertion block 8 is inserted into the jack 9. In this way, the mounting block 7 can be retracted and fixed on the same sofa module 1, avoiding the mounting block 7 and the connecting rod 6 protruding from the side of the sofa module 1 when not connected and used.

[0033] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
