The anti-tilt wheel 15 can effectively prevent the wheelchair from falling when driving, especially when passing through uneven ground or slope. This design greatly improves the safety and stability of the device, and is especially suitable for the elderly or users with difficulty in moving.

[0039] Guardrails 16 are arranged on the top of the seat 7 on the front and rear sides, which are used to preliminarily prevent the user from falling off the seat 7. One side of the guardrail 16 is connected with a rotating sleeve 17, and the rotating sleeve 17 is fixedly connected with a baffle 18. When the user sits on the chair, the nursing staff or the user can pull the baffle 18 to make the right side of the baffle 18 enter the inside of the fixed plate 20, and the baffle 18 is clamped with the clamping rod 21. This design can effectively fix the waist of the user, prevent falling from the top of the chair during lifting or movement, and further improve the safety of the device. The clamping design is characterized in that the waist fixing device of the user can be quickly released by pulling the clamping rod 21, which is convenient for getting on and off the wheelchair or quickly handling in emergency.

[0040] In order to improve the experience of the user, the top of the seat 7 is provided with a cushion 23, which increases the comfort of the user. In addition, the design of the guardrail 16 also makes the process of the user getting on and off the wheelchair more safe and convenient. The left side of the seat 7 is also provided with a containing groove 22 at the front and rear ends, which is used for containing the legs of the user, further increasing the comfort and stability of the seat 7.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
