Abstract

The invention discloses a detachable angle-adjustable self-locking folder. The folder comprises a front joint, a rear joint, a handle and a screw rod, wherein one sides of the front joint and the rearjoint are hinged, one end of the handle is connected with the rear joint, and a jacking rotating pin is arranged on the inner side surface of the free end of the handle; one end of the screw rod is in threaded connection with the jacking rotating pin and can rotate around a shaft core of the jacking rotating pin, and the other end of the screw rod is a hemisphere head; and a sphere head groove isformed in the free side of the front joint, and the hemisphere head of the screw rod is embedded into the sphere head groove of the front joint by rotating the handle so as to fold and lock the frontjoint and the rear joint. According to the detachable angle-adjustable self-locking folder, the front joint and the rear joint can be completely detached, and the secondary self-locking can be implemented. The detachable angle-adjustable self-locking folder is simple in structure, convenient to use and reasonable in stress, the self-locking is relatively reliable, and the service life is prolonged.

Description

technical field [0001] The invention relates to a mechanically connected locking structure, in particular to a self-locking folder that can be conveniently used for folding electric vehicles. 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. General folding bicycles or folding electric vehicles all realize the folding of the front and rear wheels by a folder installed on the crossbeam of the car. Folders are also called hinge locking devices. 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. Such as figure 1 Shown, a kind of self-locking folder, it comprises: a ...
