Abstract

The traditional well-known folding bicycle is complicated to operate, burdensome to carry after being folded and inconvenient to carry outside. The invention provides a double-shaft self-locking folding device. The design scheme of the invention is that a taper rotating shaft assembly is designed and a self-locking press plate assembly is additionally arranged; during assembling and using, an upper open press plate (15) and a lower open press plate (10) are fixed on the taper rotating shaft assembly; and a self-locking press plate assembly is also mounted on a shaft coupling bracket seat (5) to obtain the double-shaft self-locking folding device. The double-shaft self-locking folding device is advantaged in that the folding bicycle with small volume can be manufactured to provide great convenience for travelers; walking fatigue problem is especially solved for tourists; and the bicycle can be used for putting personal belongings after being folded into a luggage cart and can be easily pushed in places where are inconvenient for riding; therefore, the the tires of the travelers in the journey are greatly relaxed.

Description

Technical field: [0001] The invention relates to a folding bicycle, which is mainly used on a folding bicycle and a folding electric vehicle. Background technique: [0002] Currently known folding bicycles are cumbersome to operate, cumbersome to carry after folding, and are inconvenient to carry when going out. Invention content: [0003] In order to solve the use defects of existing products, the invention provides a "two-axis self-locking folder", which can be conveniently used on various folding bicycles. [0004] Using this "two-axis self-locking folder", various folding bicycles can be manufactured. This folding bicycle can be folded into a trolley for storing travel articles, and can also be manufactured into a folding electric bicycle. [0005] Design: [0006] The design scheme of the present invention is: design a kind of " taper rotating shaft assembly ", wherein comprise: connecting shaft (1), taper bushing (3), taper outer axle sleeve (4), limit plate (14); ...
