Description

Anti-off type fine adjustment quick release structure

The present invention relates to a bicycle quick release structure, and more particularly to an anti-off type fine adjustment 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 (or the fork body on the frame).

However, there are many types of bicycles, such as mountain bikes, snowmobiles, downhill vehicles, and road vehicles. 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 screwed with the internal thread on the frame to enhance the impact resistance. . 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. There is a concern that the foreign object collides and the quick release structure is loosened. However, if the lever is forcibly fixed upward, there is a problem of looseness or overtightening.

Therefore, the inventors have developed a fine-tuning quick release structure, which mainly adds a fine adjustment unit between the shaft and the trigger, and can perform axial fine adjustment displacement by the inner and outer sleeves of the fastening mechanism. The fine adjustment unit and the fork body can generate some micro-supply levers for rotation and then tighten. However, this fine-tuning quick-release structure is Before being assembled on the frame, the outer sleeve is easily inadvertently played by the user, and the one end of the external thread is disengaged from the shaft, which causes the component to be easily lost.

In view of the above, in order to improve the prior art, the conventional quick release structure has the problem that the parts are easily detached; therefore, the present invention provides an anti-off type fine adjustment quick release structure, comprising: a shaft with a spindle and a connection a shaft having a fixed end and a fine adjustment end coupled to the fixed end, the fixed end has a mandrel external thread on the outer peripheral surface, the end face of the fine adjustment end has a mandrel internal thread, and the fine adjustment end outer circumference The upper portion has a small diameter portion adjacent to the end surface and a large diameter portion connected to the small diameter portion. The outer diameter of the small diameter portion is smaller than the outer diameter of the large diameter portion, and the small diameter portion is connected to the large diameter portion. Forming a retaining end surface, the coupling shaft has a first external thread at one end, and a second external thread at the other end, the first external thread is screwed with the inner shaft of the mandrel of the spindle; a lever has a The internal thread of the positioning post is screwed to the second external thread of the shaft; a fine adjustment unit has an inner sleeve and an outer sleeve, the inner sleeve has an axial through hole and a fine adjustment external thread The outer sleeve has a hollow ring shape, and the inner circumference of the outer sleeve The utility model has a small diameter hole and a large diameter hole communicating with the small diameter hole, wherein the inner diameter of the small diameter hole is smaller than the inner diameter of the large diameter hole, and the hole wall of the small diameter hole has a fine adjustment internal thread, the outer casing The fine adjustment internal thread of the cylinder is screwed on the fine adjustment external thread of the inner sleeve, so that the outer sleeve can be rotated by an external force to reciprocate along the axial direction of the inner sleeve, and the inner sleeve is through the through hole For the shaft of the shaft to pass through, the inner diameter of the large diameter hole is larger than the outer diameter of the large diameter portion of the shaft, and the inner diameter of the small diameter hole is smaller than the outer diameter of the large diameter portion of the shaft; thereby preventing the parts The effect of prolapse.
