Description

Technical Field

[0001] The utility model belongs to the technical field of children's health care, and in particular relates to a sitting posture adjusting device. Background Art

[0002] Childhood is one of the key periods of growth and development for children. Children's bones are not fully developed, and they contain more protein and less calcium and phosphorus. Therefore, the bones are relatively soft and elastic, and are prone to bending when compressed, especially when the spine is immature and the physiological curvature has not yet been fully formed. If you maintain an incorrect posture for a long time, it is easy to cause scoliosis and deformation of the spine, affecting the normal physiological function of the spine and causing lifelong damage.

[0003] With the continuous intensification of social competition, parents are increasingly inclined to improve their children's competitiveness from childhood. Children's study time has occupied most of their lives. In learning, because children have low self-control, they often sit in a bad posture such as bending over, hunching over or sitting close to the book to relax because of fatigue. The biggest problem caused by bad sitting posture is myopia and scoliosis.

[0004] In order to prevent the adverse effects of bad sitting posture on children, parents often use sitting posture correctors to make children maintain the correct sitting posture. However, the current sitting posture correctors, such as the one with patent number CN212972477U, include a base, a vertical axis tube, a chest baffle seat, a latch slot set on the chest baffle seat, a latch with a spring in the latch slot, a latch fixing hole set on the vertical axis tube, and a shoulder correction rod device. The height of the device can be changed by the cooperation of the latch and the latch hole so that children of different heights can use it. However, the device does not have a device to guide the position of the child's arms. In the correct sitting posture, the child's hands need to be in an "eight" shape, naturally and relaxedly placed flat on the table, with both elbows outward, commonly known as "arm open". Incorrect arm placement can easily lead to changes in other body positions of the child or affect the child's comfort, thereby affecting the child's maintenance of the correct posture, and finally may lead to poor training results. Utility Model Content

[0005] The utility model discloses a sitting posture adjusting device, which is intended to solve the technical problem that the existing sitting posture correcting device is not provided with an arm position guide, which may affect the training effect.

[0006] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0007] A sitting posture adjustment device comprises a fixing device, one side of which is provided with a first limiting device for preventing a body from leaning forward, the fixing device is also provided with a traction device, the traction device comprises a first traction device and a second traction device which have the same structure and are symmetrically arranged on both sides of the fixing device, the first traction device comprises a first traction plate, the first traction plate is connected to a second traction plate, the first traction plate and the second traction plate are located on the same horizontal plane, the second traction plate is inclined toward a side close to the fixing device, and an angle formed between the first traction plate and the second traction plate is less than 90 degrees, and the second traction plate is provided with a baffle for limiting the movement of a hand toward the first traction plate or / and away from the first traction plate.

[0008] After adopting this technical solution, the first traction plate and the second traction plate are located on the same horizontal plane, the second traction plate is inclined to the side close to the fixing device, and the angle formed between the first traction plate and the second traction plate is less than 90 degrees, so that an "eight"-shaped traction channel can be formed between the two second traction plates, and the user's (such as a child) arms can be naturally relaxed and placed on the traction channel. The baffle can limit the user's arms from tipping over, so that the user can achieve a relaxed "arm-open" effect when using the device, increase the user's comfort in adjusting the sitting posture, and make it easier for the user to maintain the correct sitting posture for a longer period of time. The first limit device can limit the position of the user's body and head and shoulders, so that the user's body is upright, prevent the user's body from leaning forward, and improve the training effect. The fixing device can be used to fix the device on any desktop where the user needs to train the sitting posture, increasing the practicality of the device.

[0009] Among them, the first traction plate is hinged to the second traction plate, and a limiting groove and a limiting block are respectively arranged on the contact surfaces of the first traction plate and the second traction plate. The angle less than 90 degrees formed between the first traction plate and the second traction plate is connected by a return spring, and the baffle is provided with one piece and is located on the side of the second traction plate close to the return spring.

[0010] After adopting this technical solution, through the hinge connection between the first traction plate and the second traction plate, the second traction plate can be rotated in a certain plane towards the direction close to the fixing device under the guidance of the user's arm movement, and a force along this direction is applied to the reset spring. The reset spring can be extended and retracted to reset the second traction plate. During this process, the device can adapt to the user's arm movement, increase the user's comfort, and at the same time re-tug and remind the user's arm position.

[0011] Wherein, the fixing device comprises a U-shaped plate, a plurality of bolts are threadedly connected to the U-shaped plate, and each of the bolts is arranged to penetrate one side of the U-shaped plate.

[0012] After adopting this technical solution, the bolts can be connected to the desktop to tighten the bolts and fix the device on the desktop, so that it is convenient for users to perform training.

[0013] Wherein, silicone pads are arranged on opposite sides of the inner wall of the U-shaped plate, and anti-slip grooves are arranged on the silicone pads. A suction cup is arranged on the side of the inner wall of the U-shaped plate where the silicone pad is not arranged.

[0014] After adopting this technical solution, the friction between the U-shaped board and the desktop can be increased by the anti-slip grooves on the silicone pad, and the suction cup can suck one side of the U-shaped board to the desktop tightly, further increasing the fixing effect of the U-shaped board to the desktop from three directions.

[0015] Wherein, the first limiting device comprises a telescopic plate, a first vertical pole is arranged on a side of the telescopic plate away from the fixing device, the first vertical pole is a telescopic structure, and a shoulder limiting device is arranged on the top of the first vertical pole.

[0016] After adopting this technical solution, the lateral distance between the first upright pole and the table top can be adjusted by extending and retracting the telescopic plate. The lateral distance is the lateral distance from the user's chest to the table top, that is, the distance of the user's fist. The longitudinal distance of the first upright pole can also be adjusted, thereby changing the longitudinal distance of the shoulder limit device, thereby adapting to users of different heights.

[0017] Wherein, the shoulder limiting device comprises cross bars symmetrically arranged at two ends of the first vertical rod, and each of the cross bars is detachably connected with an L-shaped rod.

[0018] After adopting this technical solution, the chest position of the user's body can be restricted by the horizontal bar to prevent the body from leaning forward, and the shoulder position of the user can be restricted by the L-shaped bar to keep "shoulders level" and avoid shrugging and uneven shoulders.

[0019] Wherein, a side of each cross bar away from the fixing device and an inner side wall of each L-shaped bar are provided with a cushion.

[0020] After adopting this technical solution, the setting of the soft pad can increase the comfort of the contact part between the user's body and the device.

[0021] Wherein, a second upright pole is arranged on the top of the first upright pole, the second upright pole is a telescopic structure, and the second upright pole is connected to a chin limiting device.

[0022] After adopting this technical solution, the longitudinal position of the chin limit device can be changed by extending and retracting the second vertical rod. The chin limit device can limit the position of the user's head and prevent the head from tilting downward, so that users of different heights can use it, thereby increasing the practicality of the device.

[0023] Wherein, the chin limiting device is an arc-shaped plate.

[0024] After adopting this technical solution, the curved plate can support the user's chin, fit the human body curve, and bring a better experience.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0026] (1) The first traction plate, the second traction plate and the return spring are used to traction the user's arms. When the user uses the device to maintain a correct sitting posture, the arm position can be traction-reminded to maintain an "arm open" state, thereby improving the training effect of the correct sitting posture and extending the training time of the user for training the correct sitting posture.

[0027] (2) The use of silicone pads with anti-slip patterns, suction cups, and bolts increases the contact area between the desktop and the inner side of the U-shaped plate, and the friction, suction, and pressure are used to further increase the fixing effect of the device and the desktop.

[0028] (3) The shoulder limit device can be used to limit the user's shoulder position, so that the user can maintain a "shoulders level" state during sitting training, which cooperates with the "arms open" state to increase the training effect.

[0029] (4) The telescopic plate and the first and second vertical poles with telescopic structures enable the device to be used by users of different heights, thereby increasing the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
