Description

Technical Field

[0001] The invention relates to the technical field of sitting posture correction chairs, in particular to a sitting posture correction chair for children with cerebral palsy. Background Art

[0002] Cerebral palsy is a disease caused by damage to the brain during development, which is common from the fetal period to one month after the baby is born. It is usually caused by various reasons such as lack of oxygen, infection or accidental injury, and the degree of damage will not worsen over time. As a common motor disorder in childhood, the combination and severity of symptoms shown by each patient may vary.

[0003] During the rehabilitation treatment of children with cerebral palsy, a sitting posture correction chair is needed to correct their sitting posture to avoid bowing their heads and hunching over for a long time. However, the arm rest plate above the existing sitting posture correction chair is generally fixed and cannot be adjusted, so that the space inside the correction chair cannot be changed, and thus it cannot be used for children of different ages, reducing the applicability of the sitting posture correction chair. In view of the above problems, the inventor proposes a sitting posture correction chair for children with cerebral palsy to solve the above problems. Summary of the invention

[0004] In order to solve the problem that the armrest plate above the sitting posture correction chair is generally fixed and the internal space of the seat cannot be changed; the purpose of the present invention is to provide a sitting posture correction chair for children with cerebral palsy.

[0005] To solve the above technical problems, the present invention adopts the following technical scheme: a sitting posture correction chair for children with cerebral palsy, comprising a sitting posture correction chair body, the sitting posture correction chair body comprising a bearing structure, a supporting structure, a lifting structure and a placing structure, the supporting structure is arranged above the bearing structure, the lifting structure and the placing structure are arranged below the bearing structure, the supporting structure comprises a supporting frame, an arm placing plate is slidably arranged between the supporting frames, sliders are fixedly arranged on both sides of the arm placing plate, the slider is slidably arranged in the supporting frame, a cross plate is slidably arranged in the slider, a pull rod is fixedly arranged on the bottom surface of the cross plate, the pull rod is slidably inserted into the slider, a second spring is fixedly connected between the inner wall of the slider and the cross plate, a positioning rod is slidably inserted into one side of the slider, an inclined rod is fixedly arranged on one side of the positioning rod, the inclined rod slides through the cross plate, the positioning rod is slidably inserted in the supporting frame, a slide groove is opened in the supporting frame, the slider is slidably arranged in the slide groove, a positioning groove is opened in the supporting frame, and the positioning rod is slidably inserted in the positioning groove;

A locking universal wheel 405 is installed on the bottom surface of the movable rod 402.

[0036] By adopting the above technical solution, the bolt 404 is removed to disengage it from the groove 403, and then the movable rod 402 is slid in the sleeve 401. When it is adjusted to a suitable height, the position of one of the grooves 403 is the same as the position of the bolt 404, and then the bolt 404 is inserted into the corresponding groove 403 again, so that its height can be adjusted, thereby facilitating caregivers of different heights to care for the sick children.

[0037] Working principle: first, disassemble the bolt 404 to disengage it from the groove 403, then slide the movable rod 402 in the sleeve 401, and when it is adjusted to a suitable height, the position of one of the grooves 403 is the same as the position of the bolt 404, and then insert the bolt 404 into the corresponding groove 403 again, so that its height can be adjusted, so as to facilitate caregivers of different heights to take care of sick children, and then rotate the screw rod 503 to make the movable block 504 slide in the fixed plate 502, and drive the first fixed seat 505 to move, so that one end of the guide rod 506 rotates in the first fixed seat 505, and the other end rotates in the second fixed seat 508, so that the ankle-foot placement plate 507 drives the rotating member 511 to rotate on the outer surface of the connecting rod 510, so that the angle of the ankle-foot placement plate 507 can be adjusted;

[0038] The pull rod 310 is then pulled to make the cross plate 309 slide in the slider 306 and squeeze the second spring 311.
