TECHNICAL FIELD
[0001] The utility model relates to sofa technical field, concretely is a detachable sofa. BACKGROUND
[0002] In modern home life, as an indispensable important furniture, the function and design of sofa have been concerned all the time. Traditional sofa structure forms are various, however, most sofas have the problem of inconvenient disassembly in design, which brings many troubles to users.
[0003] On the one hand, many traditional sofas adopt fixed structure, and the components are connected together through welding, riveting or a large amount of glue bonding. This connection mode makes the sofa become a whole after assembly, which is difficult to disassemble. When the user needs to move the sofa, for example, in the case of moving, changing the living place or re-arranging the home space, since the sofa is large in size and cannot be disassembled, the moving process is extremely difficult. Not only a large amount of manpower and material resources are consumed, but also the moving may fail because the sofa cannot pass through the narrow passage or door hole, and even the sofa itself or the surrounding walls, door frames and the like are damaged in the moving process.
[0004] Therefore, we design a detachable sofa. CONTENT OF THE UTILITY MODEL

[0009] Further, the plug-in connecting piece comprises a rotating column, the side wall of the rotating column is connected with a limiting ring, a plurality of evenly distributed insertion holes are opened on the side surface of the rotating column, and a plurality of threaded rods equal to the number of insertion holes are further connected.
[0010] Further, the thickness of the box wall of the side box and the middle box is greater than the length of the rotating column, the length of the limiting ring is less than the length of the rotating column, and the limiting ring plays a limiting role on the rotating column.
[0011] Further, the two plug-in connectors are rotated to adjust the angle, and the threaded rods on the two plug-in connectors are inserted into the insertion holes of the other.
[0012] Further, the plurality of backrest boxes are arranged on the side boxes and the middle boxes.
[0013] Further, the top of the side box and the middle box is provided with an insertion slot, and the backrest box is plug-connected with the insertion slot.
[0014] (Three) beneficial effects
[0015] Compared with the prior art, the detachable sofa has the following beneficial effects:
[0016] The detachable sofa is connected by the insertion slot, and the backrest box is pulled out for disassembly and inserted for installation, which is simple to operate. The connection between the side box, the middle box and the middle box is twisted off the nut, and the threaded rod is separated from the insertion hole by rotating the rotating column, so that the boxes are separated. Reverse operation can be performed during assembly. This design greatly simplifies the disassembly and assembly process of the sofa, and ordinary users can easily complete the operation without professional tools and complex operation steps, which is convenient to use when moving, changing the placement position or storing, saves time and effort.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] Please refer to Figs. 1-2 The detachable sofa of the utility model is composed of two side boxes 1, a plurality of middle boxes 2 and a plurality of backrest boxes 5 arranged on the side boxes 1 and the middle boxes 2.
[0022] The top wall of the side box 1 and the middle box 2 is provided with a slot near the back side, and the backrest box 5 can be directly inserted into the slot to realize the assembly with the side box 1 or the middle box 2; when disassembled, the backrest box 5 is pulled out of the slot.
[0023] The bottom of the side box 1 and the middle box 2 is designed as an opening. The side wall of the side box 1 and the two side walls of the middle box 2 are all provided with a circular mounting hole, and the hole wall of the mounting hole is provided with an annular recessed groove. The mounting hole and the recessed groove are used for mounting the plug-in connector 3.
[0024] The plug-in connector 3 includes a rotating column 6, and the side wall of the rotating column 6 is connected with a limiting ring 7. The rotating column 6 is installed in the mounting hole, and the limiting ring 7 is located in the recessed groove, both of which are rotationally connected. The thickness of the box wall of the side box 1 and the middle box 2 is greater than the length of the rotating column 6, and the length of the limiting ring 7 is less than the length of the rotating column 6. The limiting ring 7 can limit the rotating column 6 to prevent it from sliding out of the mounting hole.
[0025] A plurality of insertion holes 8 are uniformly distributed in an annular array on the outer end surface of the rotating column 6. Each two adjacent insertion holes 8 are stably connected with a threaded rod 9, so that the number of the insertion holes 8 is equal to the number of the threaded rods 9, and the included angle formed by each threaded rod 9 and the adjacent two insertion holes 8 is also completely the same, which ensures the symmetry and uniformity of the structure.
[0026] The length of the threaded rod 9 is greater than the length of the insertion hole 8, and the threaded rod 9 is provided with a nut 4.
[0027] As described above, when the sofa is assembled, first, a plurality of middle boxes 2 are arranged in close contact to form the main middle part of the sofa. Then, two side boxes 1 are placed on the two sides of the middle box 2, at this time, the plug-in connectors 3 on each box are aligned with each other. Then, rotate the rotating column 6 to make the threaded rod 9 align with the corresponding insertion hole 8 and insert it. When all the plug-in connectors 3 are inserted into each other, tighten the nut 4 on the threaded rod 9, and through the fastening effect of the nut 4, the side box 1 and the middle box 2 are firmly connected together to complete the assembly of the sofa main body. Finally, the backrest box 5 is inserted into the slot on the top of the side box 1 and the middle box 2, and the assembly of the entire sofa is completed.
[0028] When the sofa needs to be disassembled, first, use a suitable tool to unscrew the nut 4 on the threaded rod 9. With the loosening of the nut 4, the connection between the side box 1 and the middle box 2 through the plug-in connector 3 is released. Then, gently rotate the rotating column 6 to gradually separate the threaded rod 9 from the corresponding insertion hole 8. When the threaded rod 9 is completely pulled out of the insertion hole 8, the side box 1 and the middle box 2 can be smoothly separated. Repeat the above operation to release the connection between all the side boxes 1 and the middle boxes 2 one by one, so that each box is separated from each other. Finally, the backrest box 5 is pulled out vertically upward from the slot on the top of the side box 1 or the middle box 2, at this time, the entire sofa has been disassembled into a plurality of independent parts, which is convenient for carrying and storing.
[0029] The detachable sofa guarantees the stability and comfort of the sofa in the use process through the ingenious structural design and reasonable connecting mode, realizes convenient and fast disassembly and assembly, and provides great convenience for users.
[0030] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
