Description

Technical Field

[0001] The utility model relates to the technical field of tricycle foot brake equipment, in particular to a tricycle foot brake frame. Background Art

[0002] The foot brake of a tricycle is an important component of the tricycle's braking system. It is usually connected to the foot brake pedal, and braking is achieved by stepping on the foot brake pedal. Existing tricycle foot brake frames mainly include a brake pedal and a foot brake elbow. The foot brake elbow is connected to the braking system. The structure is simple, and braking is achieved by stepping on the brake pedal in conjunction with the braking system. However, existing brake frames are not very sensitive during the pedaling process. When the pedal is stepped on, the foot brake elbow rotates sluggishly, which cannot effectively transmit the braking force to the braking system to achieve braking. Furthermore, the foot brake elbow is affected when resetting, causing brake failure. Utility Model Content

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0017] A tricycle foot brake frame, such as Figures 1 to 3 As shown, it includes a foot brake bend pipe 1 and a rubber composite anti-slip pedal 2. The foot brake bend pipe 1 is installed at one end of a foot brake bend pipe mounting bracket 3. The other end of the foot brake bend pipe mounting bracket 3 is connected to a bearing mounting seat 4. The foot brake bend pipe 1 is connected to the brake system through the bearing mounting seat 4.

[0018] The bearing mounting seat 4 is used to install the bearing 12, the bearing 12 is installed on the bearing fixing shaft 5, the bearing fixing shaft 5 is installed on the rotating shaft mounting seat 6, and the rotating shaft mounting seat 6 is also provided with a limiting component for limiting the resetting of the foot brake elbow 1.

[0020] A return spring 11 is also installed between the bearing mounting seat 4 and the rotating shaft mounting seat 6 to drive the foot brake elbow 1 to return to its original position.

[0021] The middle part of the return spring 11 is sleeved on the bearing fixed shaft 5 , one end of the return spring 11 is connected to the return spring connecting plate 9 on the bearing mounting seat 4 , and the other end is connected to the rotating shaft mounting seat 6 .

[0022] The limiting assembly includes a limiting pier mounting frame 7 mounted on the rotating shaft mounting seat 6, and a rubber limiting pier 8 is installed on the limiting pier mounting frame 7 for contacting the end face of the foot brake elbow mounting frame for limiting when the foot brake elbow is reset.

[0023] The rubber limiting pier 8 is made of rubber material and has a certain elasticity, which can buffer the impact when the foot brake elbow 1 is reset.

[0024] When in use, the foot brake bend pipe 1 is rotated around the bearing fixed axis 5 by stepping on the rubber composite anti-slip pedal 2, and the braking force is transmitted to the braking system through the bearing mounting seat to complete the braking. When the rubber composite anti-slip pedal is no longer stepped on, the foot brake bend pipe 1 is automatically reset under the drive of the reset spring 11, and the foot brake bend pipe is limited by the rubber limit pier 8 to prevent the foot brake bend pipe from excessive rebound.
