Manual foldable bicycle for old people

Abstract

The invention provides a manual foldable bicycle for old people, and belongs to the field of foldable bicycles. According to the technical scheme, folding latches on a front sleeve and a rear supporting shaft of the bicycle are alternately arranged in upper limiting holes and lower limiting holes of the front sleeve and the rear supporting shaft, and a sliding rod lock cylinder on a sliding rod is alternately arranged in an upper limiting hole and a lower limiting hole in a sliding way, so that a main body structure of the bicycle is folded or unfolded. The manual foldable bicycle for the old people has the advantages that the problems that after the traditional foldable bicycle is folded in the front-back direction, the structure is unstable, and the folded bicycle is difficult to drag are solved, the bicycle can be conveniently and quickly folded or unfolded by a single person, the time and the labor are saved, and moreover, the manual foldable bicycle is simple in structure and light in weight, facilitates the old people, and has certain market value.

Description

technical field [0001] The invention relates to a manual folding bicycle for the elderly, and belongs to the field of folding bicycle supplies. Background technique [0002] Folding bicycles are relatively common in the market. In our daily life, we can often find the shadow of folding bicycles. However, the functions of this type of folding bicycles are relatively single, and the designs are often the same. In the eyes of many people, they are labeled as "unsafe and unstable". mark. Moreover, most of the folding bicycles are aimed at young people, and very few take care of the needs of the elderly. For example, a folding bicycle designed by Liu Ye (Patent No. CN103587626) has improved the problem of folding bicycle suspension chains, but its folding method is still the most common front and rear folding mode on the market, which can reduce the weight of the bicycle. The volume is good for storage, but for the elderly, there are still difficulties in carrying (for example,...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems in the background technology that the foldable bicycles have the same folding methods and face a single group of people, the present invention proposes a simple and easy-to-understand method, using two position-limiting holes processed on the cylinder to cooperate with Cylindrical pins, through the conversion of the pins between the two limiting holes, realize two different forms of the bicycle, namely the normal driving mode before folding and the mode after folding
