Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically to a bicycle front fork with better resistance to deformation. Background Technology

[0002] The front fork is the key component that determines the comfort of a bicycle. The front fork is located at the front of the bicycle structure. Its upper end is connected to the handlebar assembly, the frame assembly is connected to the head tube, and the lower end is connected to the front axle assembly, forming the bicycle's steering system.

[0003] The bicycle front fork structure mainly consists of two columnar structures located at the front of the bicycle. When the bicycle is in motion or parked, it is inevitably affected by external environmental factors. For example, the bicycle front fork structure is easily impacted, which may result in minor paint damage or even deformation, affecting the normal use of the bicycle.

[0004] Therefore, we propose a bicycle front fork with better resistance to deformation to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bicycle front fork with better resistance to deformation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A bicycle front fork with good anti-deformation effect includes a fork tube, a top sleeve is fixedly installed on the top of the fork tube, a lower sleeve is fixedly installed on the lower part of the outer ring of the fork tube, and anti-collision strips are fixedly installed at equal intervals on the bottom of the top sleeve.

[0007] Preferably, the anti-collision strip is a memory metal strip with a certain elasticity, and the bending direction of the anti-collision strip is outward.

[0008] Preferably, the top of the lower sleeve has buffer holes at equal intervals, and the bottom of the anti-collision strip is inserted through the buffer holes on the lower sleeve.

[0009] Preferably, a ring is provided at the upper end of the anti-collision strip located in the inner cavity of the buffer hole, and a buffer spring is fitted on the outer ring of the anti-collision strip located in the inner cavity of the buffer hole.

[0010] Preferably, the buffer spring is located at the bottom of the ring, and the upper and lower ends of the buffer spring abut against the bottom of the ring and the bottom of the inner wall of the buffer hole, respectively.

[0011] Preferably, the buffer hole is an inverted U-shaped hole structure, and the bottom of the anti-collision strip passes through the buffer hole and extends to the outside of the lower sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When a collision occurs, the impacting object first contacts the anti-deformation strip of this bicycle fork. Upon impact, the anti-deformation strip contracts, converting the kinetic energy of the collision into its own potential energy. If the impact force is not too great, the anti-deformation strip itself can achieve the anti-collision function, thus improving the deformation resistance of the bicycle fork.

[0013] This bicycle fork, with its superior resistance to deformation, will simultaneously use the ring sleeve to compress the buffer spring when the impact force is large and the anti-collision strip is deformed by the pressure. This will convert part of the impact force into the potential energy of the spring, further improving the bicycle fork's anti-collision and anti-deformation capabilities. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a bicycle front fork technical solution with better resistance to deformation: Example

[0018] A bicycle front fork with good anti-deformation effect includes a fork tube 1, a top sleeve 2 fixedly installed on the top of the fork tube 1, a lower sleeve 3 fixedly installed on the lower part of the outer ring of the fork tube 1, and anti-collision strips 4 fixedly installed at equal intervals on the bottom of the top sleeve 2.

[0019] Among them, the anti-collision strip 4 is a memory metal strip with a certain elasticity, and the bending direction of the anti-collision strip 4 is outward.

[0020] Among them, the top of the lower sleeve 3 is provided with buffer holes 7 at equal intervals, and the bottom of the anti-collision strip 4 is inserted through the buffer holes 7 on the lower sleeve 3.

[0021] Among them, the anti-collision strip 4 is provided with a ring 5 at the upper end of the inner cavity of the buffer hole 7, and a buffer spring 6 is fitted on the outer ring of the anti-collision strip 4 in the inner cavity of the buffer hole 7.

[0022] The buffer spring 6 is located at the bottom of the ring 5, and the upper and lower ends of the buffer spring 6 abut against the bottom of the ring 5 and the bottom of the inner wall of the buffer hole 7, respectively.

[0023] Specifically, the buffer hole 7 is an inverted convex shape, and the bottom of the anti-collision strip 4 passes through the buffer hole 7 and extends to the outside of the bottom of the lower sleeve 3.

[0024] In this embodiment, when the bicycle is used normally, the bicycle front fork is mainly susceptible to interference from external environmental factors on the side and front, i.e., collision. When a collision occurs, the object first contacts the anti-collision strip 4. The anti-collision strip 4 will retract upon impact, thereby converting the kinetic energy of the collision into its own potential energy. If the impact force is not too great, the anti-collision strip 4 can achieve the anti-collision function on its own, thus improving the square deformation capability of the bicycle front fork.

[0025] When the impact force is large, and the anti-collision strip 4 is deformed by the extrusion force, the ring sleeve 5 will simultaneously squeeze the buffer spring 6 downward, converting part of the impact force into the potential energy of the spring, which further improves the anti-collision and deformation resistance of the bicycle front fork.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
