Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bicycle accessories, especially to a bicycle front fork with high stability. BACKGROUND

[0002] With the improvement of people's life concept, more and more people accept cycling, and people realize the purpose of green travel or body building through cycling. The bicycle front fork is an important component in the bicycle structure, and the front fork component is located in the front part of the bicycle structure. Its upper end is connected with the handle component, the frame component cooperates with the front tube, and the lower end cooperates with the front shaft component to form the guiding system of the bicycle. The front fork has a shock absorbing function. In cycling, the front fork is compressed under stress, and after reaching the extreme point, it rebounds to the original length (the rebound speed is affected by the damping). It is repeatedly repeated to reduce the body stress of the rider, reduce the bump, and achieve the purpose of comfort.

[0003] Among them, the bicycle gas pressure fork usually injects gas in the left and right sleeve. When the vehicle body is jolted, the piston in the sleeve slides, and the damping effect of the compression gas is relied on to achieve the buffering of the jolt. In the prior art, the gas pressure fork does not have a gas leakage protection function. When the sealing performance is reduced or the sealing element is damaged and leaks after long-term use, the damping effect of the stroke tube of the front fork will be reduced, the shock absorbing function of the front fork will be reduced or even lost, and the rider will be physically injured. The stroke tube will collide with the fork barrel to cause damage to the front fork and make it unusable. SUMMARY

[0004] Therefore, the utility model provides a bicycle front fork with high stability to solve the technical problems in the background art.

[0007] Preferably, the compensation damping mechanism comprises a damping spring fixed to the upper end of the fork shoulder mounting seat and a crash ring fixed to the lower end of the damping spring.

[0017] The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] The utility model will be described in detail below in combination with the drawings, such as Figure 1 As shown in the embodiment described in the utility model, the bicycle front fork with high stability comprises an upper tube 1 connected with a bicycle handlebar, a fork shoulder 2 fixedly connected to the bottom of the upper tube 1, two stroke tubes 4 fixedly connected to the fork shoulder mounting seat 3 at both ends of the fork shoulder 2, two gas pressure fork barrels 5 respectively sleeved outside the two stroke tubes 4, a fork bridge 7 bridged and fixed between the fork barrel mounting seats 6 at the upper ends of the two gas pressure fork barrels 5, a front mudguard 8 rearward mounted at the center of the bottom of the fork bridge 7, a fork leg 9 bridged between the fork barrel mounting seats 6 at the lower ends of the two gas pressure fork barrels 5 for being fixed to the center of a bicycle front wheel, and a compensation damping mechanism 10 fixed to the fork shoulder mounting seat 3 and suspended outside the two stroke tubes 4.

[0019] The bicycle front fork with high stability described in the embodiment has the compensation damping mechanism 10 suspended and added outside the two stroke tubes 4, which can provide air leakage protection for the bicycle front fork. When the stroke tube 4 and the gas pressure fork barrel 5 are connected and air leakage occurs, the stroke tube 4 will be pressed downward into the gas pressure fork barrel 5. When the stroke tube 4 is lowered to the compensation damping mechanism 10 touching the gas pressure fork barrel 5, the compensation damping mechanism 10 starts to work, providing a compensation damping for the front fork and providing safety protection for the rider, avoiding the reduction or even loss of the front fork damping function, which may cause physical injury to the rider, and also avoiding the rigid collision between the stroke tube 4 and the gas pressure fork barrel 5 due to the reduction or even loss of the front fork damping function, which may cause damage to the front fork and make it unusable.
