Description

Technical Field

[0001] The utility model relates to the technical field of sitting posture correcting tools, in particular to a sitting posture corrector. Background Art

[0002] It is known that the sitting posture corrector is one of the main means to prevent myopia and hunchback in children and adolescents at present, so the stability of the use of the corrector plays a decisive role in the prevention and treatment effect. Although there is also a sitting posture corrector disclosed in the Chinese utility model patent with the authorized patent number CN219147038U, the corrector is provided with a hinge seat; the vertical rod has a connecting portion extending toward the corrector; the end of the connecting portion close to the corrector has an inclined portion gradually protruding outward along the direction close to the corrector; the connecting portion is rotatably connected with the hinge seat. In this embodiment, the hinge seat is two convex arms, which are arranged on the side of the top chest piece away from the user, that is, the back, and the hinge seat is preferably arranged on the upper half of the back; the inclined portion gradually protrudes toward the user side from the bottom to the top, and the hinge seat is connected to the upper half of the inclined portion near the top through a shaft column. Since the upper half of the inclined portion is more convex than the lower half, and the corrector is installed on the inclined portion in a hinged form, the corrector can swing along the hinge seat in the vertical direction. In some other embodiments, the inclination direction of the inclined portion is changed to gradually convex outward from top to bottom, and the corresponding effect is also established. It can be seen that the rotation range of the hinged seat is limited by the fact that one end of the correcting member has an inclined portion that gradually protrudes outward along the direction close to the correcting member. However, for the inclined portion that gradually protrudes outward along the direction close to the correcting member, this will increase the difficulty of processing and production, and further increase the investment in production costs, which is not conducive to mass production requirements.
