DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0021] Example:

[0022] This embodiment is a sitting posture corrector with a writing board, such as Figure 1 As shown, it includes a connected writing board 1 and an extension board 4. The front of the writing board 1 is provided with a groove, and a soft cushion is laid in the groove. The soft cushion can be made of materials such as industrial leather, rubber and silicone. A limit stop 3 is provided at the junction of the writing board and the back of the extension board. The limit stop 3 is used to abut against the edge of the table. After the limit stop is abutted against the edge of the table, the extension board can limit the distance between the human body and the table to avoid the distance between the human body and the table being too small. The left and right sides of the extension board can also support the user's arms to improve comfort. A correction stop 5 is vertically arranged at the edge of the extension board. The correction stop 5 is in an arc shape close to the chest and abdomen of the human body. Two first flexible mechanisms 6 are symmetrically arranged on the front of the correction stop 5. In addition, a correction bracket 7 is also provided on the front of the extension board. Two second flexible mechanisms 8 are symmetrically arranged on the correction bracket 7. The two first flexible mechanisms and the two second flexible mechanisms cooperate to achieve four-point support for the human body, which can provide a better correction effect.

[0023] like Figure 2 and Figure 3 As shown, the first flexible mechanism includes a first flexible body 61 and a first mounting plate 62. The first flexible body is provided with a first mounting edge, and the first mounting edge is provided with a plurality of screw holes. The first mounting plate 62 is provided with screw hole columns at positions corresponding to the screw holes. The screws pass through the screw hole columns and the screw holes in sequence to fix the first flexible body 61 on the front of the first mounting plate 62. A first buckle 65 is provided on the back of the first mounting plate 62. A positioning groove 64 matching the first mounting plate is provided on the front of the correction stop edge. The positioning groove is provided with a first mounting hole 63 and a plurality of embedded grooves, wherein the first buckle 65 matches the first mounting hole, and the embedded groove matches the screw hole column. A "J"-shaped protective plate is provided at the back of the correction stop edge corresponding to the first mounting hole. The "J"-shaped protective plate can prevent the user's fingers from contacting the first buckle, and prevent the user's fingers from being scratched by the first buckle. At the same time, the "J"-shaped protective plate can also improve the mechanical strength of the correction stop edge, and prevent the correction stop edge from breaking. In this embodiment, the first flexible body is made of rubber or silicone.

[0024] like Figure 4As shown, the correction bracket includes a vertical rod 72 and an arc head 71 horizontally arranged at the upper end of the vertical rod. The vertical rod 72 is lifted and lowered on the extension plate, and two second flexible mechanisms are symmetrically arranged on the arc head. A limiting column 73 is arranged on the side of the vertical rod 72, and an embedded groove 42 is arranged on the extension plate. A fixing seat 41 is fixedly arranged in the embedded groove, and a fixing cylinder 9 is fixedly arranged in the fixing seat. Through grooves 91 are arranged on both sides of the fixing cylinder 9 corresponding to the limiting columns. A rotating cylinder 10 is arranged on the outer sleeve of the fixing cylinder 9, and a thread 101 is arranged on the inner wall of the rotating cylinder. The vertical rod 72 is slidably arranged in the rotating cylinder, and the limiting column 73 passes through the through groove 91 and extends into the thread. In this embodiment, the correction bracket can be adjusted in height to suit users of different heights. When adjusting the height of the correction bracket, the rotating cylinder 10 is rotated to drive the limit column to move up and down through the thread on the inner wall of the rotating cylinder, thereby causing the vertical rod to move up and down. In addition, since the limit column passes through the through groove of the fixed cylinder, and the fixed cylinder does not rotate, the vertical rod itself will not rotate under the action of the screw when the vertical rod moves up and down, ensuring that the angle of the correction bracket remains unchanged.
