Description

Technical Field

[0001] This utility model relates to the field of motorcycle lever technology, and in particular to a motorcycle brake lever that prevents loosening. Background Technology

[0002] The working principle of a motorcycle brake lever is based on the lever principle. It transmits the force of the rider's brake pedal to the brake caliper through the lever, thereby achieving the braking effect. Specifically, when the rider presses the brake pedal and pulls the lever, the force is transmitted to the brake caliper through the lever. The piston inside the caliper is under pressure and pushes the brake pads to clamp the brake disc, thereby generating friction to slow down or stop the vehicle.

[0003] The existing connection between the lever and the brake pedal is fixed by a bolt assembly. However, over time, the nuts and bolts in the bolt assembly may loosen and fall off. When the bolt falls off the lever, the connection between the lever and the brake pedal fails, rendering the brakes unusable. Therefore, we propose an anti-loosening motorcycle brake lever to solve the above problems. Utility Model Content

[0004] This invention provides a motorcycle brake lever that prevents loosening, solving the technical problem that current bolt assemblies are prone to loosening from the lever.

[0005] To solve the above-mentioned technical problems, this utility model provides a motorcycle brake lever that prevents loosening, including a lever body, a connector at one end of the lever body, a threaded portion at the end of the lever body away from the connector, a lifting hole plate between the connector and the threaded portion, an anti-loosening stop on one side of the connector, one end of the anti-loosening stop being hinged to the side wall of the connector, and an elastic hook between the other end of the anti-loosening stop and the side wall of the connector.

[0006] Preferably, the anti-detachment stop is L-shaped.

[0007] The above technical solution effectively prevents the bolt assembly from falling off the connector by using an L-shaped anti-detachment stop.

[0008] Preferably, one end of the elastic hook is fixed to the side wall of the anti-detachment stop, and the other end of the elastic hook is detachably hooked to the side wall of the connector.

[0009] The above technical solution is adopted: one end of the elastic hook is fixed to the side wall of the anti-detachment component, and the other end of the elastic hook is detachably hooked to the side wall of the connector. The elastic hook is hooked on the side wall of the connector so that the anti-detachment component can prevent the bolt assembly from falling off the connector.

[0010] Preferably, the connector is U-shaped.

[0011] The above technical solution uses a U-shaped connector to facilitate connection with the brake pedal.

[0012] Preferably, a positioning plug is provided between the connector and the pull rod body.

[0013] The above technical solution employs a positioning plug between the connector and the pull rod body to facilitate welding between them.

[0014] Preferably, the positioning plug includes a positioning slot opened on the connector head and a positioning plug opened on the end of the pull rod body away from the threaded portion.

[0015] The above technical solution is adopted: the positioning plug includes a positioning slot opened on the connector head and a positioning block opened on the end of the pull rod body away from the threaded part. The positioning block is inserted into the positioning slot to facilitate the welding of the connector head and the pull rod body.

[0016] Preferably, the hoisting hole plate is located at half the length of the tie rod body.

[0017] The above technical solution involves setting a hoisting plate at half the length of the tie rod body to make the tie rod body more stable.

[0018] Preferably, the hoisting plate is arranged perpendicular to the tie rod body.

[0019] The above technical solution involves setting the hoisting plate perpendicular to the tie rod body, which enables the tie rod body to be hoisted onto the motorcycle, making the tie rod body more stable.

[0020] Preferably, a limit stop ring is also provided on the threaded portion.

[0021] The above technical solution is adopted by setting a limit ring on the threaded part. The threaded part is used to connect with the brake caliper. Of course, the travel of the brake pedal can be achieved by adjusting the position of the brake caliper on the threaded part. The limit ring is used to limit the adjustment position of the brake caliper on the threaded part.

[0022] Compared with related technologies, this utility model has the following beneficial effects:

[0023] 1. Compared to traditional motorcycle brake levers, this utility model incorporates an anti-disengagement stop and an elastic hook. One end of the lever body has a connector for connecting to the brake pedal via bolts. The end of the lever body away from the connector has a threaded portion for connecting to the brake caliper. The brake pedal travel can be adjusted by changing the position of the brake caliper on the threaded portion. A lifting plate is provided between the connector and the threaded portion. This lifting plate allows the lever body to be suspended parallel to the motorcycle by suspending the middle portion of the lever body. An anti-disengagement feature is provided on one side of the connector. The stop and anti-disengagement stop are hinged at one end to the side wall of the connector, and an elastic hook is provided between the other end of the anti-disengagement stop and the side wall of the connector. When the brake pedal and the connector of the lever body are connected by the bolt group, the elastic hook is hooked on the side wall of the connector, so that the screw part of the bolt group is blocked by the anti-disengagement stop. So even if the nut of the bolt group is loose, the screw will not fall off the connector, and the connection between the brake pedal and the lever body can still be achieved, thus not affecting the braking function. Of course, in order to further prevent the nut from loosening, an anti-loosening washer can be added between the nut and the side wall of the connector. Attached Figure Description

By hooking the elastic hook 7 onto the side wall of the connector 2, the anti-detachment stop 6 can prevent the bolt group 9 from falling off the connector 2. The connector 2 is U-shaped, which facilitates connection with the brake pedal.

[0035] A positioning plug 8 is provided between the connector 2 and the pull rod body 1 to facilitate welding of the connector 2 and the pull rod body 1. The positioning plug 8 includes a positioning slot 81 opened on the connector 2 and a positioning block 82 opened at the end of the pull rod body 1 away from the threaded part 3. The positioning block 82 is inserted into the positioning slot 81 to facilitate welding of the connector 2 and the pull rod body 1.

[0036] The lifting plate 4 is set at half the length of the tie rod body 1 to make the tie rod body 1 more stable. The lifting plate 4 is set perpendicular to the tie rod body 1 to enable the tie rod body 1 to be lifted onto the motorcycle, making the tie rod body 1 more stable. A limit ring 5 is also provided on the threaded part 3. The threaded part 3 is used to connect with the brake caliper. Of course, the travel of the brake pedal can be adjusted by adjusting the position of the brake caliper on the threaded part 3. The limit ring 5 is used to limit the adjustment position of the brake caliper on the threaded part 3.
