Self-locking folder

Abstract

The invention discloses a self-locking folder which comprises a front joint and a rear joint, wherein one end of the front joint is hinged with one end of the rear joint. A free end of the rear joint is hinged with a handle, a locating pin is arranged on the upper portion of the handle, and a tightening pin is fixed on the lower portion of the handle. The locating pin penetrates through a connecting rod, wherein the upper end of the connecting rod is provided with a bolt hole. The lower end of the connecting rod is in butt joint with the tightening pin through threads. The connecting rod is further provided with a safety hook mechanism. A free end of the front joint is provided with a self-locking boss. The self-locking boss and the safety hook mechanism are matched to achieve closing and tightly locking between the front joint and the rear joint. The self-locking folder is capable of achieving a self-locking function of bicycles, simple and convenient to use, and firm.

Description

technical field [0001] The invention relates to a mechanically connected locking structure, in particular to a self-locking folder. Background technique [0002] Bicycle, as a kind of important means of transportation, is always welcomed by people since it came out. Folding bicycles are more advantageous due to their small size after folding, convenient storage and transportation, so folding bicycles have gradually become one of the important tools for people to travel and exercise. Generally, folding bicycles or electric bicycles are folded through a folder, which is also called a hinge locking device. With the continuous development of folding bicycles, most of the existing folders use a device similar to a bayonet mechanism to achieve snap-fit ​​self-locking. However, when this device is locked, the pulling force or driving force between the front and rear vehicle bodies is concentrated on the bayonet pin, and the bayonet pin is easily deformed under the concentrated loa...

With the continuous development of folding bicycles, most of the existing folders use a device similar to a bayonet mechanism to achieve snap-fit ​​self-locking. However, when this device is locked, the pulling force or driving force between the front and rear vehicle bodies is concentrated on the bayonet pin, and the bayonet pin is easily deformed under the concentrated load of such force, and it is not easy to unfold after folding. , the fastening part is easy to become loose, and the whole folder is not easy to unfold and fold
