Description

Prevent tong folding mechanism's old wheelchair Technical Field The utility model relates to the technical field of senile wheelchairs, in particular to an senile wheelchair with an anti-pinch folding mechanism. Background Under the background that the social aging degree is continuously deepened, as the population number of the aged is continuously increased, the situation that the aged is inconvenient to move due to physical function decline is more common, the traditional auxiliary walking tool is difficult to meet the diversified demands of the aged in comfort, safety and functionality, the aged wheelchair is an auxiliary moving tool specially designed and manufactured for the aged, the movement is realized through manpower driving or electric driving, along with the development of material science, mechanical manufacturing technology and intelligent control technology, the modern aged wheelchair adopts light high-strength materials to improve portability, the design of seats and backs is optimized, the comfort is enhanced, and the walking ability and life quality of the aged are effectively improved. Because the existing senile wheelchair generally relates to a plurality of movable parts and connecting parts, if no anti-pinch design exists in the folding process, the parts such as fingers, skin and the like of a user or a nursing staff are very easy to clamp between folding joints, gaps or parts, so that crush injury is caused. Therefore, the senile wheelchair with the anti-pinch folding mechanism is provided.
