Bar chair with rotation function

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0014] Example. A bar chair with swivel function, constituted as Figure 1 to Figure 3 As shown, it includes a chair support frame 1 with a round platform structure, a connecting ring 2 is provided in the middle of the chair support frame 1, a rotating stool surface 3 is provided above the chair support frame 2, and a seat cushion 4 is provided above the rotating stool surface 3; The chair support wooden frame 1 includes 4 legs 5 arranged in a circular truncated structure, the upper end of the legs 5 is provided with a support plate 6, the support plate 6 is provided with a threaded hole 7, and the lower end of the support leg 5 is provided with a non-slip pad 8 . The support plate 6 is also provided with a positioning inclined block, and the fixing groove 304 is also provided with a groove corresponding to the positioning inclined block.

[0015] The rotating stool surface 3 includes a fixed seat 301 fixed to the chair support wooden frame 1, and a rotating seat 302 is arranged above the fixed seat 301; 6 matching fixing groove 304, a circular groove 305 is provided above the seat body 303, an annular clamping groove 306 is provided on the inner wall of the circular groove 305, and a plurality of annularly arranged mounting holes 307 are provided at the bottom of the circular groove 305, and the mounting holes A spring 308 and a positioning ball 309 are sequentially arranged in the 307 .

[0016] The fixing slot 304 is provided with a fixing hole 310 corresponding to the threaded hole 7 .

[0017] The rotating seat 302 includes a rotating cylinder 311 matched with the circular groove 305, a positioning hole 312 corresponding to the mounting hole 307 is provided at the bottom of the rotating cylinder 311, and a mounting plate 313 is provided above the rotating cylinder 311; The outer wall of 311 is provided with two symmetrically arranged convex strips 314, and the convex strips 314 are matched with the annular slot 306; a telescopic rod 315 is arranged between the inner wall of the convex strip 314 and the outer wall of the rotating cylinder 311, and the telescopic rod 315 is covered A compression spring 316 is provided; a roller 317 is provided on the outer wall of the annular raised strip 314 .

[0018] The working process of the present invention: by manually compressing the convex strip and the roller, the rotating cylinder enters the circular groove. After the roller reaches the annular groove, it elongates under the action of the spring force, and the roller contacts the annular groove. The installation hole and The positioning holes are matched, and the positioning is carried out by positioning balls. During the rotation process, the rotating seat is rotated, and the roller moves along the annular slot. At the same time, the lower end surface of the rotating cylinder contacts the positioning ball, and the positioning ball is compressed, so that the positioning ball drives the compression spring to contract. When the next positioning hole appears, the positioning The ball resets under the action of the spring force to realize positioning and limit.
