[0025] Example 1

[0026] like Figure 1-2 As shown, the utility model provides a technical solution:

[0027] A modular sofa assembly, which at least includes but is not limited to a main connection part 1 and a matching connection part 2; the matching connection part 2 is arranged at one end of the main connection part 1, and a first connection surface 11 arranged along a first direction and a second connection surface 12 arranged along a second direction are arranged on the main connection part 1, and the first connection surface 11 and the second connection surface 12 are transitioned in an arc shape, and the matching connection part 2 is provided with a third connection surface 21 along a third direction and a fourth connection surface 22 along a fourth direction, and the third connection surface 21 and the fourth connection surface 22 are located in the same plane. The third direction and the fourth direction are not arranged in a colinear manner, and a connection hole 3 is arranged on both the main connection part 1 and the matching connection part 2.

[0028] Based on the above structure, the first connecting surface 11 can be fixed to the part to be connected in the first direction through the main connecting part 1, and the second connecting surface 12 can be fixed to the part to be connected in the second direction. Fixing the part to be connected in different directions can, on the one hand, make the connection more stable, and on the other hand, adapt to the shape of the part to be connected to prevent the main connecting part 1 from twisting and slipping when subjected to increased force; similarly, a third connecting surface 21 and a fourth connecting surface 22 are provided at the end of the main connecting part 1, which are respectively connected to different sides of another part to be connected, so as to make the connection more stable.

[0029] As an example, the first direction and the second direction are set at a predetermined angle, and the predetermined angle range can be 30° to 180°. The angle range of the first direction and the second direction can be adaptively adjusted according to the shape of the part to be connected, so that the main connecting part 1 can fit better with the part to be connected.

[0030] As an example, the cross-section of the first connecting surface 11 and the second connecting surface 12 is L-shaped, and the angle between the first direction and the second direction is 90°. In this embodiment, the parts to be connected are usually wooden squares. Therefore, setting the angle to 90° can make the first connecting surface 11 and the second connecting surface 12 have more contact area with the adjacent side surfaces of the wooden square, so that the connection and fixing effect is better.

[0031] As an example, the third direction is set at 90° to the fourth direction, so that another connecting member can be fixed in two mutually perpendicular directions. This embodiment is usually used to connect the wooden square and the side panel 5. The wooden square is connected to the main connecting part 1, and the side panel 5 is connected to the auxiliary connecting part. Through this connecting member, the installation steps can be simplified, the installation accuracy can be improved, and the assembler can perform the installation more accurately and efficiently.

[0032] As an example, at least two layers of three groups of connection holes are provided on the first connection surface 11 and the second connection surface 12; each layer of three groups of connection holes on the first connection surface 11 includes at least two connection holes 3, each layer of three groups of connection holes on the second connection surface 12 includes at least one connection hole 3, and the number of three connection holes in the three groups of connection holes on each layer of the first connection surface 11 is not less than the number of three connection holes in the three groups of connection holes on each layer of the second connection surface 12.

[0033] Based on the above structure, by providing at least two layers of three groups of connecting holes on the first connecting surface 11 and the second connecting surface 12, the main connecting portion 1 can form an extension structure for the wooden square. When the length of the wooden square is not enough, the three groups of connecting holes on the first connecting surface 11 and the second connecting surface 12 can be connected to the wooden square at different positions so that the overall length after installation is just between the two side panels 5, thereby increasing the overall adjustment capability.

[0034] As an example, a first arc angle 4 is provided between adjacent sides of the third connecting surface 21 and the fourth connecting surface 22 , and the curvature of the first arc angle 4 matches the curvature of the component to be connected.

[0035] Based on the above structure, a special first arc angle 4 is provided at the end of the main connection part 1 to match the arc of the main connection wood 6 connected to the sofa frame to prevent interference with the wood and affect the wood.

[0036] As an example, the first connection surface 11 is used to connect with the upper end surface of the member to be connected, and the second connection surface 12 is used to connect with the side end surface of the member to be connected. The third connection surface 21 and the fourth connection surface 22 are used to connect with different parts of the side plate 5.

[0037] Example 2

[0038] like Figure 3 As shown, the utility model provides a technical solution:

[0039] An assembly system includes side panels 5, main connecting wood squares 6, rear baffles 7 and lower connecting strips 8; the main connecting wood squares 6, rear baffles 7 and lower connecting strips 8 are arranged parallel to each other, the side panels 5 are arranged on both sides of a frame structure composed of the main connecting wood squares 6, rear baffles 7 and lower connecting strips 8, the main connecting wood squares 6 and the side panels 5 are connected as a whole through a modular sofa assembly part, a functional extension bracket 10 can be arranged in the frame structure between the main connecting wood squares 6, rear baffles 7 and lower connecting strips 8, and a rear baffle 9 is arranged between the rear baffles 7 and the lower connecting strips 8.

[0040] Based on the above structure, the combined sofa assembly can firmly connect the main connecting wood 6 and the side panel 5 into one, reducing the overall assembly difficulty and effectively preventing the main connecting wood 6 from twisting or tilting when subjected to external force. The structure of the entire assembly is simple, and for ordinary installers, the assembly is relatively simple, and the disassembly and maintenance are also relatively simple. Through the use of the assembly, the installation of the stretch-function sofa product can be simplified, and the stability and durability of the product can be improved.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
