[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figures 1-7 As shown, a freely combinable magnetic sofa includes two bases 1, with a backrest 4 fixedly installed on the back of each of the two bases 1. A magnetic disassembly assembly 2 is movably connected to the side of the two bases 1 that is far apart from each other, and a combination assembly 3 is movably connected to the lower end of the two bases 1.

[0031] The magnetic disassembly assembly 2 includes two handrails 21. The front and rear of the two handrails 21 on opposite sides are provided with splicing grooves 22. Positive magnetic plates 23 are fixedly installed on the inner walls of the two splicing grooves 22. Negative magnetic plates 24 matching the two positive magnetic plates 23 are fixedly installed on the middle of the two bases 1 on the side away from each other and on the bottom of the two handrails 21 on the side away from each other.

[0032] The assembly 3 includes two support frames 31. The upper ends of the two support frames 31 are movably connected to the lower ends of the two bases 1 and the two backrests 4. A card plate 32 is fixedly installed in the middle left side of the right support frame 31, and a connecting groove 33 matching the card plate 32 is opened through the middle right side of the left support frame 31.

[0033] The magnetic disassembly component 2 allows for easy disassembly and assembly of the sofa. Users can easily separate or connect the armrests 21 to the base 1 as needed, facilitating sofa transport and movement, and enabling rearrangement in different scenarios. The assembly component 3 allows two complete sofas to be joined together. During operation, the user simply moves the protrusion 310 to the right and aligns the locking plate 32 on the right support frame 31 with the connecting groove 33 on the left support frame 31. After releasing the protrusion 310, two magnetic inserts 314 insert into two magnetic slots 315, securing the locking plate 32. This combines the two support frames 31 and the base 1. The operation is convenient, the structure is simple, and the support frames 31 can be separated from the base 1, facilitating manufacturing.

[0034] like Figure 4 As shown, cushions 25 are attached to the upper ends of both bases 1.

[0035] like Figure 5 As shown, positioning rods 34 are fixedly installed on the left and right sides of the lower front of the two bases 1 and the left and right sides of the lower end of the two handrails 21. The four corners of the upper end of the two support frames 31 are provided with matching positioning rods 34 insertion holes 35.

[0036] The base 1 and backrest 4 are detachably connected to the support frame 31 by the combination of the positioning rod 34 and the insertion hole 35.

[0037] like Figure 6 As shown, sliders 36 are fixedly installed at the front and rear positions of the inner wall of the left support frame 31. Slide plates 37 are slidably connected to the outer sides of the two sliders 36. A push plate 38 is fixedly installed at the middle left side of the slide plate 37.

[0038] When it is necessary to combine the two support frames 31, the user moves the push plate 38 to the right using the protrusion 310. The push plate 38 causes the slide plate 37 to move to the right outside the two slide bars 36. One end of the two rotating rods 313 rotates around the slide plate 37, and the other end causes the two guide blocks 312 to move away from each other. The two guide blocks 312 cause the two magnetic insert plates 314 to move away from each other. Then, the locking plate 32 on the other support frame 31 is moved to the left and inserted into the connecting groove 33 on this support frame 31. At this time, the two bases 1 are flush and joined together. After releasing the protrusion 310, the elastic force of the two springs 319 will cause the two guide blocks 312 to return to their original position, so that the two magnetic insert plates 314 are inserted into the two magnetic slots 315 on the locking plate 32. In this way, the two bases 1 and the two backrests 4 can be quickly combined together.

[0039] like Figure 6 As shown, a moving groove 39 for a matching push plate 38 is provided through the front right side of the support frame 31. The front left side of the push plate 38 overlaps with the left side of the inner wall of the moving groove 39. A protrusion 310 is fixedly installed on the front end of the push plate 38.

[0040] like Figure 6 As shown, a guide rail 311 is fixedly installed at the right position of the top of the inner wall of the left support frame 31. The guide rail 311 is located above the card plate 32. Guide blocks 312 are slidably connected to the front and rear parts of the inner wall of the guide rail 311. Rotating rods 313 are rotatably connected to the lower ends of the two guide blocks 312. The ends of the two rotating rods 313 away from the guide blocks 312 are rotatably connected to the front and rear parts of the lower end of the slide plate 37.

[0041] like Figure 6 As shown, magnetic insert plates 314 are fixedly installed on opposite sides of the two guide blocks 312, and magnetic grooves 315 matching magnetic insert plates 314 are opened on the left side of the front and rear sides of the card plate 32.

[0042] like Figure 7 As shown, sleeves 316 are fixedly installed at the right positions of the front and rear parts of the inner wall of the left support frame 31. Slider 317 is slidably connected to the inner wall of each sleeve 316. Moving rods 318 are fixedly installed on the opposite sides of each slider 317. The opposite ends of the two moving rods 318 are fixedly connected to the opposite sides of the two guide blocks 312. Springs 319 are fixedly connected to the opposite sides of the inner wall of each sleeve 316. The opposite ends of the two springs 319 are fixedly connected to the opposite sides of the two sliders 317.

[0043] When the guide block 312 moves, it will drive the slider 317 and the moving rod 318 to move. The spring 319 has a resetting effect on the guide block 312.

[0044] The working principle of this utility model is as follows: In use, the two armrests 21 are magnetically combined with the two bases 1 and two backrests 4 using positive magnetic plates 23 and negative magnetic plates 24. The armrests 21, backrests 4, bases 1, and seat cushions 25 together form the sofa structure. Users can easily separate or connect the armrests 21 to the bases 1 as needed, which facilitates moving and transporting the sofa, and also makes it convenient to rearrange the sofa in different scenarios.

[0045] When the two support frames 31 need to be combined, the user moves the push plate 38 to the right using the protrusion 310. The push plate 38 causes the slide plate 37 to move to the right outside the two slide bars 36. One end of the two rotating rods 313 rotates around the slide plate 37, and the other end causes the two guide blocks 312 to move away from each other. The two guide blocks 312 cause the two magnetic insert plates 314 to move away from each other. Then, the locking plate 32 on the other support frame 31 is moved to the left and inserted into the connecting groove 33 on this support frame 31. At this time, the two bases 1 are flush and joined together. After releasing the protrusion 310, the elastic force of the two springs 319 will cause the two guide blocks 312 to return to their original position, so that the two magnetic insert plates 314 are inserted into the two magnetic grooves 315 on the locking plate 32. In this way, the two bases 1 and the two backrests 4 can be quickly combined together. The two support frames 31 are combined together by a mechanical magnetic attraction method, which has strong stability.
