[0026] EMBODIMENT

[0027] Please refer to Figures 1-5 The utility model provides a kind of office chair of detachable replacement seat surface, including seat main body part 10, lower pressing fixed part 20 and positioning member 30.

[0028] Among them, the cooperation of lower pressing fixed part 20 and positioning member 30 can disassemble and assemble seat surface 120 in seat main body part 10, just corresponding size seat surface 120 can be replaced and installed.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 3 Seat main body part 10 includes chair frame 110 and seat surface 120, and seat surface 120 is placed on chair frame 110.Two groups of lower pressing fixed part 20 are respectively installed on the two sides above chair frame 110, and lower pressing fixed part 20 includes guide rail 210, movable frame 220, lower pressing member 230 and fixing member 240.Guide rail 210 is fixed with chair frame 110, movable frame 220 is slidably arranged on guide rail 210, and fixing member 240 holds seat surface 120 by pressing above movable frame 220.Positioning member 30 is installed on chair frame 110 to limit seat surface 120.

[0030] The movable frame 220 on the guide rail 210 can be inserted and installed with multiple sets of installations as needed. The lower pressing piece 230 is pressed above the movable frame 220 by the fixing piece 240, that is, the pressed lower pressing piece 230 presses and fixes the side of the chair surface 120. When the chair surface 120 needs to be replaced, only a chair surface 120 of a suitable size is needed. The lower pressing piece 230 is loosened by the fixing piece 240, the old chair surface 120 is pulled out of the chair frame 110, the new chair surface 120 is inserted above the chair frame 110, the fixing piece 240 is tightened to press the lower pressing piece 230, and the lower pressing piece 230 is pressed to fix the new chair surface 120, and the replacement and installation of the chair surface are completed. Compared with the traditional bolt installation method, the office chair with a detachable and replaceable chair surface only needs a chair surface of a corresponding size for replacement and installation, and does not need corresponding threaded holes, and has better applicability.

[0031] In the above specific embodiments, please refer to Figure 4 The fixing piece 240 includes a threaded rod 241, a knob 242, and a bottom plate 244. The bottom plate 244 is located inside the movable frame 220, the threaded rod 241 penetrates the top of the movable frame 220 and is connected with the bottom plate 244 at the bottom end, and the knob 242 is screwed with the threaded rod 241. By rotating the knob 242 and cooperating with the threaded rod 241, the lower pressing piece 230 can be fixed on the top of the movable frame 220.
