Description

A walking aid structure

technical field

The utility model relates to a walking aid structure.

Background technique

Generally, people with leg injuries or the degeneration of physiological functions due to old age make their legs weak and difficult to stand or walk easily. They often need to use walking aids such as crutches, walkers, or wheelchairs to support them in order to achieve stable standing or walking. etc. purpose.

Figure 9 shows a common crutch used to assist elderly people with degraded physiological functions to walk with weak legs or walking with disabled people. The crutch is mainly composed of a hollow main rod 6 and a support rod 7, and A buffer unit 8 is provided between the main rod 6 and the support rod 7. The buffer unit 8 mainly includes a sleeve 81, a set rod 82, and an elastic body 83 sleeved on the set rod 82. The lower end of the set rod 82 It is fixedly connected to the pole 7, and its upper end penetrates into the hollow part of the sleeve 81, and an expansion block 84 is provided on the upper end of the set of vertical poles 82, so as to force the sleeve 81 with the groove 811 on the side wall to be expanded. The block 84 presses and stretches apart, so that the stretched sleeve 81 is socketed with the hollow part of the main rod 6 , so as to achieve the purpose of assembling the main rod 6 , the support rod 7 and the buffer unit 8 together.

However, in the existing crutches, the main rod 6 and the buffer unit 8 are assembled at the junction of the main rod 6 and the buffer unit 8. The friction resistance between the expanded sleeve 81 and the inner wall of the hollow part of the main rod 6 is used as a fixed structure. When the ground anti-shock force is greater than the frictional resistance between the sleeve 81 and the inner wall of the main rod 6, it will cause the assembly structure between the buffer unit 8 and the main rod 6 to loosen, causing the length of the crutch to suddenly shrink, and the user loses support. Those who are in danger of falling.

Therefore, in view of the lack of structural design of walking aids such as crutches and other walking aids that assist the elderly or disabled users, with the assistance of their many years of manufacturing and design experience and knowledge in related fields, And after many ingenious thoughts, we made new research and development improvements for the structure of existing walking aids, and developed this creation.
