Double-locking improved structure of bicycle folder

Abstract

The invention discloses a double-locking improved structure of a bicycle folder. The double-locking improved structure is mainly characterized in that a first shell and a second shell of a third folder are abutted to a plane of a non-arc end of an arc-shaped rod head of a second clamping rod through a second penetrating shaft, so that a second locking function of the third folder can be achieved, an operation handle is pulled to deflect upwards, and a clamping socket on the operation handle drives an arc-shaped rod head of a first clamping rod to cross the highest point to achieve a first locking function, so that the third folder assuredly has double-locking functions. Particularly, all components generating the second locking function are hidden inside the first shell and the second shell and cannot be seen or directly touched from the outside, so that the components can be weather-resistant and shock-resistant, a user completely does not worry about automatic disconnection of the second locking function in the riding process, the first locking function and the second locking function can be multiplied, and a foldable bicycle can be higher in safety when in use.

Description

technical field [0001] The invention relates to a bicycle folder, in particular to an improved double locking structure of the bicycle folder. Background technique [0002] Usually, folding bicycles are equipped with folders between the pipes, so as to realize the folding function between the pipes. At present, the common folder can be installed on the main frame to facilitate the folding of the frame, and can also be installed between the handle bar and the front fork tube to fold the handle bar down, or installed on the seat post to facilitate the seat The pads are folded down, and there are several other configurations of folders that are installed in different locations. [0003] The current common bicycle folder generally includes left and right housings, one side of the left and right housings passes through a shaft and the left and right housings are pivotally connected together, so that the left and right housings can be Close together or expand with the shaft as t...

AI Technical Summary

Problems solved by technology

However, since the positioning piece 24 is simply pivotally connected to the second pipe piece 221, it is easy to loosen after being subjected to frequent vibrations during use, so that in the process of folding the bicycle, one hand must be taken into account that the positioning piece 24 does not fall, so that The folding process is extremely unsatisfactory; at the same time, when the positioning piece 24 is loose, it will occur that the second locking effect is suddenly released due to the clamping block 241 on the positioning piece 24 jumping off the jack 232 during riding, which will affect the rider’s safety. Great danger to personal safety
