Stepless adjustment sitting posture corrector

Abstract

A stepless adjustment sitting posture corrector is characterized in that the corrector comprises a body (1), a middle rod (2) and a nut (3), the inner ring of the nut (3) is in threaded connection with the middle rod (2), and the outer ring of the nut (3) makes contact with the body; the nut (3) is an expandable nut, the main body (1) is connected with the nut (3) in a clamping mode and can drivethe nut to rotate on the middle rod so as to achieve expansion of the nut, and the expanded nut (3) and the main body (1) are locked. The stepless adjustment sitting posture corrector has the advantages that stepless adjustment is achieved, adaptability is higher, the appearance surface is free of a structure, and the stepless adjustment sitting posture corrector is simpler.

Description

technical field [0001] The present application relates to the technical field of sitting posture correctors, in particular to a steplessly adjustable sitting posture corrector. Background technique [0002] With the development of society, parents are paying more and more attention to the health of their children. Poor sitting posture for a long time can cause spinal curvature, asymmetrical bulge of the back, chest hunched over, myopia and other problems. Therefore, the sitting posture corrector has gradually become an indispensable tool in the process of children's growth. [0003] At present, the sitting posture corrector on the market generally includes two parts, the upper part structure is to limit the user's writing posture (chin rest part), and the lower part is a base, which is used for fixing with the desktop. Because everyone's height is different, the chin rest part needs to be a height-adjustable structure. At present, most of the structures adopted by the chin...

AI Technical Summary

Problems solved by technology

At present, most of the structures adopted by the chin rest part in the market are button-type, that is, a structure with step adjustment, such as the adjustment structure described in CN210783585U, which is exactly a kind of step adjustment. The positioning slot and the positioning block are clamped to achieve positioning at different heights, but this positioning method is only limited to the number of slots in the positioning slot. If the position in the middle of the groove cannot be clamped to achieve fixation), it will inevitably fail to meet the user's requirements. Therefore, the adaptability of the stepped adjustment structure with a limited height like the above is not wide; The external structure such as the positioning frame needs to be set, the external structure is complicated, and the overall transfer is also troublesome
