DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0031] This embodiment mainly describes the structure of a chair that is easy to assemble and disassemble, as follows:

[0032] like Figure 1-Figure 8As shown, the chair that is easy to disassemble and assemble includes a bracket 1, and a support rod 11 is respectively arranged at the front and rear ends of the bracket 1. Further, the bracket 1 is composed of two inverted U-shaped frames, and a fixing rod is arranged at the bottom of the two U-shaped frames to connect and fix the two U-shaped frames, and the two ends of the support rod 11 are respectively fixedly connected to the two U-shaped frames; a seat surface 3, the seat surface 3 is installed on the support rod 11, and a backrest 4 is arranged on the seat surface 3; a first fastener 12, the first fastener 12 is installed at the bottom of the seat surface 3, The first fastener 12 is connected to one of the support rods 11 through a buckle groove; a limit buckle 13, wherein the limit buckle 13 is installed on the support rod 11 connected to the first fastener 12, and one side of the buckle groove of the first fastener 12 is inserted into the limit buckle 13, so that the first fastener 12 can rotate around the support rod 11 through the buckle groove, so that the inner side wall of the buckle groove of the first fastener 12 abuts against the support rod 11; a second fastener 14, wherein the second fastener 14 is installed at the bottom of the seat surface 3, and the second fastener 14 is connected to the other support rod 11 through the buckle groove.

[0033] When assembling the chair, the staff first picks up the seat 3 so that one side of the buckle groove of the first fastener 12 can be inserted into the limit buckle 13, and then rotates the seat 3 to make the bottom of the seat 3 move toward the bracket 1. At this time, the first fastener 12 can rotate around the support rod 11 installed with the limit buckle 13 through the buckle groove to make the opening of the buckle groove away from the limit buckle 13, so that the buckle groove of the first fastener 12 can be clamped to the support rod 11, and then continue to rotate the seat 3 until the buckle groove of the second fastener 14 can be clamped to the support rod 11 without the limit buckle 13 installed. Because the backrest 4 is installed on the seat 3, the assembly of the chair is completed. In this way, the arrangement of the first fastener 12 and the second fastener 14 facilitates the assembly of the chair, wherein the arrangement of the limit buckle 13 The arrangement can make the inner wall of the buckle groove of the first fastener 12 abut against the support rod 11 when the buckle groove is inserted into the limit buckle 13, so that the second fastener 14 no longer needs to adjust the position when it is clamped to the support rod 11, thereby reducing the assembly steps of the chair, improving the speed and efficiency of the chair assembly, and further facilitating the assembly of the chair. The arrangement of the limit buckle 13 can limit the first fastener 12 from moving laterally on the support rod 11, thereby improving the stability of the seat surface 3. The second fastener 14 can also be arranged into two smaller fasteners, and a connecting rod 15 is arranged between the two fasteners. The use of a smaller second fastener 14 can reduce production costs, and the arrangement of the connecting rod 15 can improve the stability of the second fastener 14.

[0034] When the chair is stored or transported, the seat 3 together with the backrest 4 is removed from the bracket 1 and then inserted into the bracket 1 from the bottom of the bracket 1. This reduces the space occupied by the chair and facilitates the transportation or storage of the chair.

[0035] When the chair is disassembled, the staff pulls the seat 3 upward from the end where the second fastener 14 is installed, so that the buckle groove of the second fastener 14 disengages from the support rod 11, and then rotates the seat 3 to make the buckle groove of the first fastener 12 enter one side of the limit buckle 13 and rotate out of the limit buckle 13. In this way, the buckle groove of the first fastener 12 can be disengaged from the support rod 11, or the seat 3 is lifted with the opening of the buckle groove of the first fastener 12 facing the bottom of the support rod 11, so that the first fastener 12 can also be disengaged from the support rod 11, which reduces the steps of disassembling the chair, improves the speed and efficiency of disassembling the chair, and further facilitates the disassembly of the chair.
