Description

Technical Field

[0001] The utility model relates to the technical field of bicycle parts, in particular to a bicycle front fork knob assembly with a steel ball integrated structure. Background Art

[0002] The main function of a bicycle fork is to fix the front wheel of the bicycle and connect the handlebars. It can be used to control the direction of the wheel when riding to complete left and right turns. With the development of the bicycle industry, it has also been given more functions by designers to bring convenience and safety to riders.

[0003] The front fork of a mountain bike has two knobs. By turning the knobs, the hardness or softness of the front fork can be adjusted or whether the front fork is locked, so that the bicycle can cope with various road conditions. The existing knob pushes a steel ball through a spring when turning, and the knob has a crisp sound and a turning feel when turning. However, the spring and the steel ball are small parts, which are not easy to remove and install during assembly, and are prone to material loss and short installation or missing installation. Therefore, a bicycle front fork knob assembly with a steel ball integrated structure is proposed. Utility Model Content

[0006] It also includes a knob, wherein a rotating column is provided at the middle of the lower end of the knob, a through hole is provided at the middle of the spring seat, and the rotating column is rotatably connected to the inside of the through hole, so as to facilitate the adjustment of the front fork;

[0007] Corrugated springs are arranged on both sides of the left and right sides of the lower surface of the knob, and the lower ends of the corrugated springs are located on the upper ends of the steel balls, so the sound is crisper and the hand feel is better.

[0008] Furthermore, the steel balls are all 4mm steel balls, and the distance between the highest point of the steel balls and the upper surface of the spring seat is 1mm to prevent the steel balls from falling off.

[0009] Furthermore, it also includes a mounting seat, the interior of the mounting seat is plugged into the exterior of the spring seat, and the upper surface of the spring seat is flush with the upper surface of the mounting seat, which is convenient for rotating the knob and more beautiful.

[0010] Furthermore, limit blocks are provided on both sides of the upper end of the spring seat, and limit grooves are provided on both sides of the inner side of the mounting seat. The limit blocks are respectively located inside adjacent limit grooves to prevent the spring seat from rotating.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When adjusting the front fork, turn the knob, and the knob drives the corrugated spring to revolve around the central axis of the rotating column. The lower end of the corrugated spring leaves the steel ball, and the corrugated spring recovers. The lower end of the corrugated spring hits the upper surface of the spring seat and makes a crisp sound. Continue to turn the knob, and the lower end of the corrugated spring rotates to the upper end of the adjacent steel ball. Compared with ordinary springs, the elastic potential energy of the corrugated spring is greater under the same compression amount, the sound is crisper, the torque required for rotation is greater, and the rotation feel is better;

[0013] 2. During installation, the steel ball and the spring seat are integrated by injection molding. The steel balls are all 4mm steel balls. The distance between the highest point of the steel ball and the upper surface of the spring seat is 1mm, which prevents the steel ball from falling off and reduces the number of parts required for assembling the bicycle front fork knob assembly with an integrated steel ball structure, making it easier to pick up and install materials.
