[0029] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] Combined with appendix Figure 1-10 A foldable and quick-installable seat, comprising a back frame 1 and a seat cushion frame 2, and armrests 3 connected to the back frame 1 and the seat cushion frame 2 respectively. The back frame 1 is mounted on the seat cushion frame 2, and the seat cushion frame 2 is bent upward to form a top interface. The back frame 1 is mounted on the top of the seat cushion frame 2, thereby maintaining a relatively vertical connection between the back frame 1 and the seat cushion frame 2, thus enabling the normal function of the seat.

[0032] The seat frame 2 has a first groove 21 at the top and a first protrusion 11 at the bottom. The shape and position of the first groove 21 and the first protrusion 11 are corresponding. The first protrusion 11 is inserted into the first groove 21, thereby mounting the back frame 1 onto the seat frame 2. When the first protrusion 11 is inserted into the first groove 21, the first protrusion 11 can make full contact with the first groove 21, thereby allowing the seat frame 2 to be stably connected with the back frame 1 to form a fitting structure. Through the fitting of the first groove 21 and the first protrusion 11, misalignment of the back frame 1 and the seat frame 2 under force can be prevented.

[0033] The connection between the seat frame 2 and the back frame 1 is made by a hinge 4, which rotatably connects the seat frame 2 and the back frame 1 together. Under the action of the hinge 4, the back frame 1 can rotate to the side of the seat frame 2, so that the surface of the back frame 1 contacts the surface of the seat frame 2.

[0034] The hinge 4 consists of an upper hinge and a lower hinge. The upper hinge and the lower hinge are connected by a pivot and are an integral structure. Both the upper hinge and the lower hinge are provided with threaded holes, which are used to fix the upper hinge and the lower hinge to the back frame 1 and the seat cushion frame 2 respectively.

[0035] The first groove 21 at the top of the seat frame 2 has a first connecting hole 22 in the side wall facing the seat frame 2. The first connecting hole 22 and the first groove 21 are independent spatial structures. The first connecting hole 22 extends from the top end of the seat frame 2 into the solid body of the seat frame 2. The side of the seat frame 2 has a first threaded hole 23 that cooperates with the first connecting hole 22 to fix the hinge. The lower hinge of the hinge 4 is inserted into the first connecting hole 22, and the lower hinge of the hinge 4 is fixed in the first connecting hole 22 by a screw through the first threaded hole 23.

[0036] The top side of the seat frame 2 is also provided with a limiting boss 24. The limiting boss 24 is located on the same side as the first connecting hole 22. The limiting boss 24 is located on the outer end face of the first connecting hole 22. The limiting boss 24 is provided with a limiting groove. The limiting groove is used to install the pivot position of the upper and lower hinges of the hinge 4. Since the connection position of the upper and lower hinges is a pivot connection with a pivot protruding structure, the pivot of the hinge is placed in the limiting groove, and the two sides of the pivot abut against the sides of the limiting boss 24 on both sides of the limiting groove, which can prevent the pivot from axially disengaging when rotating or under force.

[0037] The back frame 1 has a second connecting hole 12 in the side wall of the first boss 11 facing the seat frame 2. The second connecting hole 22 extends from the bottom of the back frame 1 into the solid body of the back frame 1. The side of the back frame 1 facing the seat frame 2 has a second threaded hole 13 that mates with the second connecting hole 12. The upper hinge of the hinge 4 is inserted into the second connecting hole 12 and fixed in the second connecting hole 12 with screws.

[0038] By fixing the upper hinge of hinge 4 to the second connecting socket 12 and fixing the lower hinge of hinge 4 to the first connecting socket 22, the back frame 1 and the seat cushion frame 2 are connected together and have a rotational engagement function.

[0039] The inner sides of the back frame 1 and the seat cushion frame 2 are respectively provided with a back frame groove 16 and a seat cushion frame groove 26. After the back frame 1 is installed on the seat cushion frame 2, the back frame groove 16 on the back frame 1 and the seat cushion frame groove 26 on the seat cushion frame 2 combine to form an integral groove. The integral groove is used to install a fixing plate 5. The shape of the fixing plate 5 corresponds to the integral groove formed by the back frame groove 16 and the seat cushion frame groove 26. The fixing plate 5 is used to limit the back frame 1 and the seat cushion frame 2. After the fixing plate 5 is installed in the integral groove, the back frame 1 and the seat cushion frame 2 cannot rotate, thus facilitating the daily use of the seat. The back frame groove 16 and the seat cushion frame groove 26 are respectively provided with connecting threaded holes. The fixing plate 5 is provided with mounting threaded holes respectively corresponding to the connecting threaded holes of the back frame 1 and the seat cushion frame 2. The fixing plate 5 is fixedly installed in the connecting threaded holes of the back frame groove 16 and the seat cushion frame groove 26 of the integral groove by passing screws through the mounting threaded holes of the fixing plate 5, so that the back frame 1 and the seat cushion frame 2 can be maintained in use.

[0040] The back frame 1 and seat cushion frame 2 are equipped with integrated mesh fabric, which serves as a support component for the seat during use. The integrated mesh fabric comes into contact with the user's limbs, making the user more comfortable when sitting on the seat. The mesh fabric 51 of the back frame is fixed to the backrest, and the mesh fabric 52 of the seat cushion is fixed to the seat cushion. There is also a suspended mesh fabric 53 at the connection between the back frame 1 and the seat cushion frame 2. The suspended mesh fabric 53 is suspended and can deform as the back frame is flipped and folded.

[0041] The left and right armrests are fixed to the back frame 1 and the seat cushion frame 2 respectively by screws 3. One end of the left and right armrests is connected to the side of the back frame 1, and the other end is connected to the side of the seat cushion frame 2.

[0042] When transporting the seat, the back frame 1 and seat cushion frame 2 can be connected by hinge 4, and then the back frame 1 and seat cushion frame 2 can be folded. This not only reduces the packaging volume and transportation costs, but also saves most of the tedious installation steps by installing the back frame 1 and seat cushion frame 2 together first.

[0043] The seats are shipped in a flip-folded state, with the armrests placed in the gaps between the seats, minimizing the packaging volume.

[0044] When using the seat, customers only need to flip the seat back frame back to the fully extended state; install the fixing plate and armrests; assemble the five-star base, casters, and gas spring; place the seat cushion back frame assembly on the gas spring, and the assembly is complete. After the fixing plate is installed, the back frame 1 and seat cushion frame 2 can be kept in the seat's use state, which is very convenient for subsequent installation of armrests, etc., and can also further stabilize the back frame 1 and seat cushion frame 2, so that they will not deform under long-term stress.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
