[0022] 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.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a chair that is easy to assemble, including a seat 1. The seat 1 includes a frame 2, a plurality of seat plates 3 are fixed on the frame 2, a plurality of support legs 4 are fixed on the lower side of the frame 2, an auxiliary support structure is installed on the support legs 4, and splicing and fixing structures are installed on the support legs 4 on both sides. The splicing and fixing structures include slots 10 and inserts 11. A rotating shaft 6 is rotatably fitted on the rear side of the frame 2, a plurality of backrest plates 8 are installed on the rotating shaft 6, and a linkage structure is installed at the end of the rotating shaft 6.

[0024] In this embodiment, the support leg 4 has an inverted trapezoidal structure, and the auxiliary support structure includes multiple auxiliary feet 16. The auxiliary feet 16 are located on both sides of the support leg 4 and are fixedly connected to the support leg 4.

[0025] Specifically, the auxiliary foot 16 can provide support, which can prevent the center of gravity from shifting and also make it easier for pedestrians to place their legs.

[0026] The slot 10 is located in the support leg 4 on one side of the seat 1. The support leg 4 on the other side of the seat 1 has a groove 15. The insert 11 corresponds to the groove 15 and the slot 10. The insert 11 is rotatably fitted with a screw 12 on one side. The screw 12 is threadedly fitted with the support leg 4. The insert 11 is fixed with a locking block 14. The slot 10 has a locking groove 13, which corresponds to the locking block 14.

[0027] Specifically, when two seats are joined together, the screw 12 is rotated to push the insert 11, so that the insert 11 enters the slot 10, and the slot 13 and the insert 14 are engaged, thus joining the two seats together.

[0028] A rotating frame 5 is fixed to the rear side of the frame 2. The rotating frame 5 is rotatably connected to the rotating shaft 6. The rotating shaft 6 is fixedly connected to the back plate 8. The linkage structure includes a socket 9 fixed to one end of the rotating shaft 6. A damping pad is installed inside the socket 9. The socket 9 corresponds to the other end of the rotating shaft 6. Nuts 7 are threaded into both ends of the rotating shaft 6.

[0029] The pivot 6 and the backing plate 8 are fixedly connected by pneumatic nails. Alternatively, a connecting plate can be welded onto the pivot 6, and the connecting plate can be connected to the backing plate 8 by ground nails or bolts.

[0030] Specifically, when it is necessary to adjust the angle of the backing plate 8, the rotating shaft 6 is rotated, which drives the backing plate 8 to rotate, thereby adjusting the angle. After the adjustment is completed, the nut 7 is rotated to fix the rotating shaft 6, thereby fixing the angle of the backing plate 8.

[0031] For two seats that are joined together, the pivot 6 is inserted into the socket 9 of the other seat. When the pivot 6 is rotated, the friction of the damping block can drive the other pivot 6 to rotate together, which makes it easy to adjust the angle of the backrest 8 of multiple seats.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
