Description
Technical Field
The utility model relates to an oil pressure brake ware field, concretely relates to anti broken brake ware that falls.
Background
The quality of braking, which is an important ring for safety of a vehicle, is often related to the life safety of a rider, especially for the rider who often needs to be in high-speed sports, if the structure and efficiency of braking are not perfect enough, even if the riding skill of the rider is higher, the rider cannot control the bicycle at will, especially under high-speed running, the impulse and the kinetic energy both reach the maximum value, if the braking cannot be smoothly performed, the life of the rider or others cannot be guaranteed, and large-scale disasters are more likely to be caused.
A brake is a device having a function of decelerating, stopping, or maintaining a stopped state of a moving member (or a moving machine). Is a mechanical part that stops or decelerates moving parts in a machine. Commonly called brake and brake. The brake mainly comprises a braking frame, a braking piece, an operating device and the like. Some brakes are also equipped with automatic adjustment of the brake clearance. In order to reduce the braking torque and the structural size, the brake is usually mounted on the high-speed shaft of the equipment, but large equipment (such as a mine hoist, an elevator and the like) with higher requirements on safety is mounted on the low-speed shaft close to the working part of the equipment.
In vehicles such as bicycles, a device for controlling a brake is a brake (commonly called a brake handle), the brake handle is a handle during braking, and the brake handle is used for a bicycle brake handle, a baby carriage handle, an electric vehicle brake handle, a motorcycle brake handle and the like.
With the continuous improvement of technical force, the brakes used by the existing vehicles such as bicycles on the market and the like gradually eliminate the traditional brakes which rely on solid media such as steel wires for transmission, and are changed into hydraulic brakes which adopt liquid media such as oil as transmission media, wherein the most representative is an oil pressure brake.
The principle of the hydraulic brake is that one end of a brake oil pipe is combined with the output end of an internal oil path of a brake handle seat, the other end of the brake oil pipe is combined with a disc brake, and the brake oil pipe can be pressed by a handle to push a piston rod of the internal oil path in a linkage manner, so that the pressure in the oil path acts on the disc brake through the brake oil pipe, and the disc brake is operated.
In the structure of the existing oil pressure brake, a transmission rod is connected between a handle and a piston rod to realize transmission, a clamp spring is also arranged in an oil path of the brake to prevent the transmission rod from being separated from the oil path, and the clamp spring is arranged in the conventional mode of clamping the clamp spring in a clamping groove arranged in the oil path.
For example, chinese patent No. 201120057013.4 discloses: an oil pressure brake driving structure at least comprises a seat body, a cylinder body, a piston, a bundling connecting piece and a pressing handle, wherein the cylinder body is arranged in the seat body, an annular oil supplementing space is formed between the outer wall surface of the cylinder body and the inner wall surface of the seat body, a piston chamber for the piston to slide is arranged in the cylinder body, the piston chamber is communicated with the oil supplementing space by one or more oil supplementing holes, and the pressing handle is pivoted on one side of the seat body and moves the piston to slide in a reciprocating mode. ".
It can be seen from the above description and drawings that the clamp springs of the existing oil pressure brake are all tightly clamped at the opening of the oil path of the brake, but the problem of the arrangement mode is that: when vehicles such as bicycles and the like are used, the vehicles are inevitably subjected to falling, the falling of the vehicles can cause the oil pressure brake arranged on the vehicles to be severely impacted, once the oil pressure brake is impacted, the piston rod in the oil way moves reversely with high probability and pushes the clamp spring for limiting the piston rod, but the clamp spring is tightly clamped with the opening of the oil way, so that the opening of the oil way of the brake is finally collided and broken to cause irreversible damage, and the whole brake is scrapped.
