[0031] In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance

[0032] ​​​In the description of the utility model, still need explaining, unless another explicit provision and limitation, "arrange", "connect" and so on term should do broad sense understanding, for example, "connect" can be fixed connection, also can be detachable connection, or integrally connected: can be mechanical connection, also can be electrical connection: can be direct connection, also can through intermediate medium indirectly connect, can be two element inside intercommunication. For ordinary skilled in the art, can understand the concrete meaning of the above-mentioned term in the utility model according to specific circumstances.

[0033] The embodiment provides an office chair with an anti-static wear-resistant seat surface, as shown in the accompanying drawings, which comprises a seat and a backrest. Figure 1 As shown in the accompanying drawings, the seat is provided with armrests on two side ends of the seat different from the backrest, the lower end of the seat is provided with a support rod, the lower end of the support rod is connected with a bottom disc, and the lower end of the bottom disc is provided with a pulley.

[0034] As shown in the accompanying drawings, in the embodiment, the seat comprises a frame 11 and a surface layer fabric covering at least the upper surface of the frame 11, the surface layer fabric at least comprises a base layer 21 connected with the frame 11 and a wear-resistant layer 22 in contact with the human body, the wear-resistant layer 22 is coated with an antistatic agent, or the wear-resistant layer 22 is provided with conductive fibers. Figure 1 The "coating of the antistatic agent" is a chemical treatment method, and the antistatic agent is preferably a bio-based antistatic agent such as a chitosan derivative; the "provision of the conductive fibers" is a physical treatment method, the conductive fibers are combined with the wear-resistant fibers or wear-resistant fabric by weaving or embedding, to finally form a wear-resistant and antistatic surface layer fabric, and the conductive fibers are preferably carbon fibers, metal fibers and the like.

[0035] In the embodiment, the surface fabric is composed of a fixed sleeve 201 arranged on the side end of the frame 11 close to the backrest and a movable sleeve 202 arranged on the side end of the frame 11 away from the backrest. The fixed sleeve 201 can be fixedly connected with the frame 11 or detachably connected with the frame 11. The movable sleeve 202 is detachably connected with the fixed sleeve 201, and at least the fixed sleeve 201 is made of surface fabric. The reason for such arrangement is that the inventor finds that the area of the seat directly contacted by the human body generally accounts for about 2 / 3 of the seat surface, and the area close to the backrest generally does not directly contact the human body, so the wear degree of the area at the front end of the seat is different from that of the area at the rear end. At the same time, the anti-static wear-resistant fabric is made through multiple processes, and the cost is high. Therefore, the inventor forms a protective layer covering the seat through the detachable connection of the fixed sleeve 201 and the movable sleeve 202, and maintains the comfort and functionality of the seat by replacing the movable sleeve 202. The advantage of such arrangement is that the local replacement reduces the consumption of the fabric, is economical, and can further improve the economy by using different fabrics for the fixed sleeve 201 and the movable sleeve 202, or improve the aesthetic appearance by using different colors.

[0036] In the embodiment, the fixed sleeve 201 and the movable sleeve 202 each include a sleeve body provided with an opening at the side end and sleeved with the end of the frame 11, and the two sleeve bodies are connected through a connecting piece. The sleeve body is formed by sewing multiple pieces of fabric or integrally formed by one piece of fabric, and only the side end of the sleeve body has an opening for the frame 11 to enter the inside of the sleeve body. The connecting piece can be any connecting structure known to those skilled in the art, such as a buckle structure, an adhesive structure, etc. It is worth noting that the upper layer of the sleeve body of the fixed sleeve 201 is short, accounting for about 1 / 3 of the upper surface of the frame 11, and the upper layer of the sleeve body of the movable sleeve 202 is long, accounting for about 2 / 3 of the upper surface of the frame 11.

[0037] In some preferred embodiments, as shown in FIG. 6, the fixed sleeve 201 and the movable sleeve 202 are connected through a connecting piece 203.
