Description

Tibetan handle quick release structure

The present invention relates to a bicycle component, and more particularly to a stalk-type quick release structure.

According to the quick release structure of the bicycle, it is mainly used to quickly combine and detach the wheel and the frame.

However, there are many types of bicycles, and the types of quick release structures to which they are applied are also different. Among them, the quick-release structure used on a mountain bike or a downhill vehicle that requires great impact resistance is provided with an external thread on one end of a shaft, and is directly screwed with the internal thread on the frame to enhance the impact resistance. force. However, this type of quick-release structure with thread and frame screw locks makes it easy to control the position of the trigger lever because the tension can only be adjusted by one of the one-sided levers. If the lever is facing down, it will be easy. The collision of foreign objects makes the quick release structure loose, but if the lever is forcibly fixed upward, it will easily lead to excessive or too tight tension between the wheel and the frame.

Therefore, as for the patent case disclosed in China No. M541974, the drive handle can be hidden to achieve a more safe effect. However, the quick release structure disclosed in this patent case has problems such as excessive parts, high manufacturing cost, difficulty in assembly, and poor market competitiveness.

In view of this, in order to improve the prior art, the conventional quick-release structure has problems such as poor safety, difficulty in adjustment, excessive parts, high manufacturing cost, difficulty in assembly, and poor market competitiveness; thus, the present invention provides a The stalk-type quick-release structure comprises: an outer shaft having an outer thread of a shaft on an outer peripheral surface of one end, at least one clamping groove on the other end surface, and an axially extending receiving hole, the receiving The hole wall has a class surface; a built-in rotating handle has a first rod body and a second rod body, and the first rod system is placed in the receiving hole of the outer shaft, the first rod body Radially convexly has a blocking portion, the second rod body has a shaft and a head, the shaft is disposed in the receiving hole, one end is pivotally connected to the first rod body, and the other end is connected to the rod head The outer diameter of the head is larger than the aperture of the receiving hole and located outside the receiving hole; a spring abuts between the class surface of the outer shaft and the blocking portion of the built-in handle; when the built-in turn When the handle is not subjected to an external force, the spring provides the elastic pre-movement of the built-in rotary handle to move into the receiving hole When the built-in rotating handle is pulled by an external force, the second rod body can be pivoted and locked into the clamping groove of the outer shaft to drive the outer shaft to rotate; thereby improving safety and having fewer parts It is simple, reduces manufacturing costs, reduces assembly difficulties, and is competitive in the market.
