Problems solved by technology

[0002] With the advancement of science and technology, many products have chosen to be folded in order to facilitate portability and save storage space, such as folding bicycles. In order to ensure safe use of existing folding bicycles, after the bicycle is unfolded by the folding mechanism, a locking mechanism is used to lock it. The connecting components are quickly locked and fixed, so that the folding mechanism will not automatically open, which will affect the driving safety. However, the locking mechanism of the existing folding joint is locked by the locking slider and the upper and lower joints. The locking structure is relatively complicated. , there are many parts, it is difficult to process and assemble, and the appearance is not neat and beautiful.

Abstract

The invention discloses a simple self-locking foldable connector which comprises an upper connector body, a lower connector body and a handle, wherein the upper connector body, the lower connector body and the handle are connected with a vertical pipe. The upper connector body, the lower connector body and the handle are connected through a hinge shaft, a wedge-shaped groove is formed in an inner wall in a cavity of the lower connector body opposite to the hinge shaft, and a wedge-shaped locking flange capable of being inserted into the wedge-shaped groove is arranged on the lower end face of the upper connector body. The simple self-locking foldable connector further comprises eccentric flat shafts between the hinge shaft and a hinge shaft installing hole of the handle and between hinge shaft installing holes of the lower connector body. The lower connector body is provided with the wedge-shaped groove, the upper connector body is provided with the locking flange matched with the wedge-shaped groove, when the handle is pulled to lock a folding mechanism, the locking flange of the upper connector body is inserted into the wedge-shaped groove of the lower connector to conduct locking directly, a locking structure is simple, part quantity is small, and installing is convenient.

Description

technical field [0001] The invention relates to a mechanical folding mechanism, in particular to a simple self-locking folding joint. Background technique [0002] With the advancement of science and technology, many products have chosen to be folded in order to facilitate portability and save storage space, such as folding bicycles. In order to ensure safe use of existing folding bicycles, after the bicycle is unfolded by the folding mechanism, a locking mechanism is used to lock it. The connecting components are quickly locked and fixed, so that the folding mechanism will not automatically open, which will affect the driving safety. However, the locking mechanism of the existing folding joint is locked by the locking slider and the upper and lower joints. The locking structure is relatively complicated. , There are many parts to form, and there are difficulties in processing and assembling, and the appearance is not neat and beautiful. [0003] Therefore, how to design a ...
