Abstract

A bicycle quick release device mainly includes an axle rod, a quick release handle and a locking member. A sleeving hole of the quick release handle is provided therein with a first hole portion which can be matched with a locking end of the axle rod, so that the quick release handle and the shaft can be coupled. The locking member is locked inwardly to the axle rod through the sleeving hole of the quick release handle. An elastic member is provided between an end of the locking member and the sleeving hole to be abutted against them and provide a telescopic tolerance for elastic displacement. Thereby, after the quick release handle is pulled out, the first hole portion and the locking end of the axle rod can be detached from each other to release the matching, so that the quick release handle can produce an idling effect to be adjusted to a preferred angular position. After being released, the quick release handle can be inwardly restored to the matching state by the elastic force of the elastic member and then continue to operate. Accordingly, the present invention adopts the operational habit, which fully conforms to human body mechanics, of pulling out and then rotating when in use, and the present invention has the characteristics of simple structure and easy to assemble, so as to have better economic benefits.

Description

Bicycle quick release device

The invention provides a technical field of bicycles, in particular to a bicycle quick release device, wherein the quick release handle is provided with an elastic member for pressing, and the normal coupling shaft is driven to be driven, and the quick release handle is pulled out when pulled out. A structural designer who can create an idling.

According to the quick release structure of the bicycle, the utility model is mainly used for quickly combining and disassembling the wheel and the frame. The conventional quick release structure mainly comprises a shaft which is placed on the axle and is screwed to the shaft. a nut at one end, a trigger that is fixed to the other end of the shaft and that can be rotated, and a wrench seat that is placed on the shaft, whereby the lever can be forced by pulling the lever The distance between the nut and the shank holder is reduced, so that the ram is pressed by the ram to achieve the effect of combining the frame with the wheel, or the lever is reversely rotated to make the nut The distance from the lever seat is increased to achieve the effect of separating the frame from the wheel. However, such a quick release structure, although simple in construction and convenient to use, is less resistant to stress and is less suitable for bicycles that are designed for high-intensity bicycles such as off-road, stunts or downhill.

As shown in the first figure, the rear triangular fork foot of the bicycle frame 10 and the bottom end of the front fork fork (not shown) are used to assemble the position of the quick release shaft. The shape of the hook 11 with the opening 12 facing downward is convenient for assembly. However, the disadvantage of such a device is that the speed of the wheel may be detached if the quick release is loose, and in order to improve the problem and to withstand it The strong quick-release shaft stress is changed to the closed pivot hole design at the pivotal joint between the rear triangular fork foot and the front fork fork foot end, that is, one side of the fork end is provided with the tooth hole 13 and the other side of the fork end is pivoted. The hole 14 (as shown in the second figure) is used for locking a shaft with a larger diameter, but since one end of the shaft needs to be tightened by a tool, it is very inconvenient, and therefore, there are many operators. The use of quick release to solve this problem, such as the patent No. I413600 of China, has the effect of achieving rapid assembly and high strength. However, the quick release structure disclosed in the above patent case has insufficient convenience in use and operation, and has too many structural parts, resulting in high assembly and manufacturing costs. In addition, patents such as Patent No. I395676, No. I593590, and Application No. 106102904, as well as the above-mentioned patents, have the same effect of achieving rapid assembly and high strength, but also have too many parts, inconvenient assembly, etc. The problem, and the two actions of pressing the design first pressure button and then pulling the quick release handle in operation and use are also less in conformity with inertia.

In view of the shortcomings of the quick release structure of the above-mentioned formula, the inventors have studied and improved the shortcomings of these shortcomings, and finally the present invention has been produced.

The main object of the present invention is to provide a bicycle quick release device, wherein the quick release handle is provided with an elastic member to be pressed, and a normal twisting shaft is generated to be driven, and when the quick release handle is pulled out, the object can be disengaged and can be idling. .

In order to achieve the above object and effect, the technical means adopted by the present invention include: a shaft rod, the shaft rod is provided with a fixed end and a locking end, wherein the locking end is an axially splicable sleeve portion And a locking hole is provided on the locking end surface; a quick release handle is provided with a set of connecting holes on the locking end of the shaft, and the sleeve hole is provided with a sleeve connected to the locking end of the shaft a first hole portion that is coupled to each other, and a second hole portion that is larger than the first hole portion at the inner end edge portion, and a third smaller diameter portion is formed toward the outer end edge of the first hole portion a fourth hole portion of the hole portion and the larger diameter; a locking member extending from the third hole portion of the quick release handle sleeve hole and locked to the center screw hole of the shaft rod, the larger diameter of which is The end portion is disposed in the fourth hole portion, and an elastic member is disposed in the end portion thereof, so that the quick release handle normal state has an elastic force of inward pressing and a spatial margin of outward displacement, so that the fast The first inner hole portion of the shank and the sleeve portion of the shaft are mutually spliced in a normal state, and can be detached to the second hole portion to form idling when displaced outward.
