[0002] A sitting posture corrector is a tool used to correct the sitting posture of children and adolescents. It can force the user to sit up straight by supporting the user's chest, and can correct the sitting posture of children and adolescents to protect their bones.

[0003] The sitting posture corrector includes components such as a fixing clamp and a supporting frame. When in use, the fixing clamp is first fixed on the desktop, and then the height of the supporting frame is adjusted. When in use, the user needs to press the chest against the supporting frame. At this time, the user's body will be forced to straighten, but the teenager must ensure that the sitting posture is correct and the head angle meets the standard. The sitting posture corrector does not have a component installed to support the user's chin. In this way, the user's head cannot be supported when using the sitting posture corrector. It is easy to lower the head too much when using it, causing neck pain, which will have an adverse effect on the normal development of children and teenagers and is not conducive to the correct correction of sitting posture. For this reason, we provide a sitting posture corrector that is easy to adjust in height to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the sitting posture corrector that is easy to adjust the height has the following beneficial effects:

[0013] The utility model cooperates among the adjusting rod, the gear, the clamping plate and the support frame. Firstly, the height of the moving cylinder and the fixed rod can be adjusted through the adjusting rod. The adjusting rod can be disengaged from the moving cylinder and the fixed rod by rotating the adjusting rod. At this time, the height of the moving cylinder and the fixed rod can be quickly adjusted, and the adjustment is very convenient. The angle of the support frame can be adjusted through the gear. When in use, the user's chin can be rested on the support frame, and the user's chin can be supported by the support frame. The angle of the support frame can be fixed by the meshing of the clamping plate and the gear, thereby improving the stability of the support frame when in use, achieving the function of supporting the user's chin, and facilitating the user to better use the sitting posture corrector.

[0014] The utility model provides components such as a clamping plate and a storage groove, and when the support plate and the bottom plate are fixed, the overall stability can be increased by the fit between the clamping plate and the desktop. The clamping plate is a structure that adapts to the edge of the desktop and can fit with the edge of the desktop during installation. When the user tilts, the support of multiple groups of clamping plates can prevent the sitting posture corrector from being offset as a whole, and prevent the sitting posture corrector from slipping. When the whole is stored, the clamping plate can be stored inside the storage groove. At this time, the space occupied by the whole when stored can be reduced, and the storage is convenient. By providing a slide groove, the paddle plate is installed inside the slide groove and does not leak out of the slide groove. In this way, when in use, it can be avoided that the paddle plate is accidentally touched, causing the card plate to be out of contact with the gear, thereby avoiding danger to the user.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 - Figure 5 As shown, the utility model provides a technical solution: a sitting posture corrector that is easy to adjust the height, including a support plate 1, the interior of the support plate 1 is rotatably connected to a threaded rod 2 through a bearing, the outer surface of the threaded rod 2 is threadedly connected to a base plate 3, the threaded rod 2 passes through one end of the base plate 3 and is connected to a knob, and the base plate 3 can be driven to move by rotating the threaded rod 2. At this time, the support plate 1 and the base plate 3 can be used to fix the whole, and the sitting posture corrector can be fixed on the desktop, and a positioning rod 17 is fixedly connected to the lower surface of the support plate 1, and the outer surface of the positioning rod 17 is slidably connected to the inside of the base plate 3, and the positioning rod 17 can increase the stability of the base plate 3 when it moves, so as to better fix the base plate 3 and the support plate 1.

[0023] The outside of the support plate 1 and the base plate 3 are both installed with an anti-skid plate 14, which can increase the stability of the support plate 1 and the base plate 3 when they are fixed, and avoid sliding and causing the whole to fall off. The inside of the support plate 1 and the base plate 3 are both provided with a storage groove 15, and the internal rotation of the storage groove 15 is connected with a splint 16, which can provide auxiliary support for the base plate 3 and the support plate 1, so that the sitting posture corrector can be prevented from being offset during use, and can be prevented from sliding after the overall offset.

[0024] A fixed cylinder 4 is fixedly connected to the upper surface of the support plate 1, and a moving cylinder 5 is slidably connected to the interior of the fixed cylinder 4. A plurality of fixing holes are opened in the vertical direction of the moving cylinder 5. An adjusting rod 6 is threadedly connected to the interior of the fixed cylinder 4. The outer surface of the adjusting rod 6 is slidably connected to the interior of the moving cylinder 5. The moving cylinder 5 can be fixed by rotating the adjusting rod 6 to enter the fixing hole on the moving cylinder 5. Conversely, the height of the moving cylinder 5 can be adjusted. A frame 7 is installed on the outside of the moving cylinder 5. The position of the frame 7 can be quickly adjusted by adjusting the moving cylinder 5 through the adjusting rod 6. It is simple and practical.

[0025] The interior of the movable cylinder 5 is slidably connected with a fixed rod 8, and the outer surface of the adjusting rod 6 is connected to the internal thread of the fixed rod 8. The fixed rod 8 can be fixed by the adjusting rod 6, and the height of the fixed rod 8 can be adjusted. An observation window 18 is provided inside the fixed cylinder 4, and the position of the adjusting rod 6 can be observed through the observation window 18, so as to facilitate the control of the adjusting rod 6 to enter the interior of the movable cylinder 5 and the fixed rod 8.

[0026] The inner wall of the fixed cylinder 4 is fixedly connected with a limiting plate 19, and the outer surface of the limiting plate 19 is slidably connected to the inside of the movable cylinder 5 and the fixed rod 8. The movement of the movable cylinder 5 and the fixed rod 8 can be limited by the limiting plate 19. Under the action of the limiting plate 19, the movable cylinder 5 and the fixed rod 8 can only move in the vertical direction, which can prevent the movable cylinder 5 and the fixed rod 8 from rotating during the movement, thereby increasing the stability of the adjusting rod 6 when adjusting.

[0027] A support frame 9 is installed on the outside of the fixed rod 8, and the user's chin can be supported by the support frame 9. Soft fabric is installed on the outside of the support frame 9 to facilitate the user to use it better and prevent the user's chin from tilting down.

The outer surface of the clamping plate 12 meshes with the gear teeth of the gear 10. When the clamping plate 12 meshes with the gear 10, the gear 10 can be fixed. At this time, the gear 10 cannot rotate, which can improve the stability of the support frame 9 when it is in use.

[0029] A slide groove 20 is provided inside the fixed rod 8, and a shift plate 21 is fixedly connected to the outer surface of the fixed block 11. The outer surface of the shift plate 21 is slidably connected to the inside of the slide groove 20. The shift plate 21 is installed inside the slide groove 20 and does not leak out of the slide groove 20. When in use, the shift plate 21 can be avoided from being accidentally touched, causing the card plate 12 to be out of contact with the gear 10.

[0030] A spring 13 is fixedly connected to the lower surface of the fixed block 11, and the other end of the spring 13 is fixedly connected to the inner wall of the fixed rod 8. Under the push of the elastic force of the spring 13, the clamping plate 12 and the gear 10 can be controlled to be tightly engaged, which can improve the stability of the support frame 9 when the angle is fixed.

[0031] Working principle: When in use, first open the clamping plate 16, control the rotation of the threaded rod 2 and fix the whole through the support plate 1 and the bottom plate 3, the clamping plate 16 can be rotated and stored through the storage groove 15, and the adjusting rod 6 can be rotated to adjust the angle of the moving cylinder 5 and the fixed rod 8. At this time, the adjusting rod 6 will be out of contact with the moving cylinder 5 and the fixed rod 8, and the height of the moving cylinder 5 can be adjusted. Then the adjusting rod 6 is rotated to the inside of the moving cylinder 5. At this time, the position of the moving cylinder 5 is stably fixed. After adjusting the height of the fixed rod 8, the adjusting rod 6 can be controlled to enter the inside of the fixed rod 8. At this time, the fixed rod 8 will be stably fixed. When adjusting the angle of the support frame 9, first push the dial plate 21 downward to control the card plate 12 to disengage from the gear 10. At this time, the support frame 9 can be rotated to adjust the angle. After releasing the dial plate 21, the card plate 12 will mesh with the gear 10 under the action of the spring 13, and the angle of the support frame 9 is stably fixed.
