DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings. Figure 1-9 As shown:

[0030] A rotatable posture correction cushion comprises a posture correction cushion body 1, wherein the posture correction cushion body 1 comprises a cushion area 11 and a backrest area 12, wherein the backrest area 12 can be deformed backward to provide a user with back support; and comprises a rotating body 2, wherein the rotating body 2 is located below the cushion area 11, and the rotating body 2 raises the cushion area 11, so that the posture correction cushion body 1 is suspended above the rotating body 2, so that the posture correction cushion body 1 will not interfere with the rotation during the rotation process, and the user places the rotating body 2 on a plane for use. The rotating body 2 comprises an upper bracket 21 and a lower bracket 22, wherein the upper bracket 21 and the lower bracket 22 are hinged, and the upper bracket 21 is fixed or integrally formed below the cushion area 11, and preferably an integrally formed method is adopted, so that the stability of the product will be better, and of course, the specific upper bracket and the cushion area are fixed or integrally formed by the manufacturer according to the actual situation. A flange 229 is arranged on the outer side of the lower bracket 22, and the flange 229 covers the upper bracket or the lower edge of the upper bracket. The purpose of setting the flange 229 on the lower bracket 22 is: a. The flange provides built-in protection for the upper bracket; b. The posture correction cushion may be placed on a chair with a certain degree of softness for use, so the rotating body will have a certain degree of sinking, and the flange is used to protect it so as not to affect the rotation of the rotating body.

[0031] At least one first annular groove 211 is provided below the upper bracket 21, and a second annular groove 221 corresponding to the first annular groove 211 is provided above the lower bracket 22, and the ball bearing 24 is placed between the first annular groove 221 and the second annular groove 221. Through this structure, the ball bearing 24 can support the connection between the upper bracket 21 and the lower bracket 22 for rotation, thereby reducing the rotation resistance of the two. Preferably, two first annular grooves and a second annular groove are provided, so that better support can be provided and a larger load can be borne.

[0032] The positioning frame 23 includes a ball positioning opening 232, and the balls 24 are placed in the ball positioning opening 232. Under the action of the positioning frame 23, the balls 24 are evenly arranged on the first annular groove 211 and the second annular groove 221. The positioning frame 23 positions the balls 24 so that the balls are stably and evenly distributed on the annular grooves, thereby ensuring stable support.

[0033] A positioning column is provided in the middle of the lower bracket 22, and the positioning frame middle ring 231 of the positioning frame is sleeved on the outer side of the positioning column. During normal movement, the positioning frame middle ring does not contact the positioning column. Once a lateral deviation occurs, the positioning frame middle ring abuts against the positioning column to assist in resetting and reduce the probability of offset. The positioning column is the outer ring of the lower recessed portion mentioned below.

[0034] The upper bracket or the cushion area is provided with an upper recessed portion 111, and the lower bracket is provided with a lower recessed portion 222, and the two ends of the rotating shaft are respectively built into the upper recessed portion 111 and the lower recessed portion 222. The rotating shaft is hidden and protected by the upper and lower recessed portions, and the bulge is avoided, making the product appearance more beautiful. The rotating shaft can be common components such as rivets, screws, bolts, and screws. The rotating shaft needs to have a locking function to prevent the upper bracket 21 and the lower bracket 22 from separating. The attached figure shows a solution in which the screw 3 is used as the rotating shaft: the screw 3 is inserted from the upper recessed portion 111 at the upper end of the cushion area 11, and then is locked by the nut 31 set in the lower recessed portion 222.

[0035] The cushion area 11 and the backrest area 12 are paved with soft cushions, which cover the upper recessed portion 111. This structure effectively avoids misoperation, and the screws can be rotated and removed only after the cushions are opened, ensuring the stability of the structure. The cushions are not marked in the attached drawings, and the cushions can be two, one paved in the cushion area and one paved in the backrest area; the cushion can also be a whole sheet, paved in both the cushion area and the backrest area.

[0036] The outer side of the upper bracket 21 is provided with an annular convex rib 219, and the annular convex rib 219 is located in the flange 229 of the lower bracket. The cooperation between the annular convex rib 219 and the flange 229 makes the connection position between the upper bracket 21 and the lower bracket 22 tighter, and it is not easy for debris to enter the cavity between the two.

[0037] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
