[0002] With the rapid development of bicycle and electric bicycle industries, the requirements for brakes are getting higher and higher. Many high-end models use hydraulic brakes. For the aesthetics of the models, most hydraulic disc brakes use internal frame routing. When the brake manufacturer ships, the brake pump and the oil pipe joint need to be separated for easy transportation. When the subsequent assembly factory assembles, the oil pipe needs to be inserted into the frame near the caliper and out from the handlebar, and then the oil pipe and the pump are locked with screws.
[0003] The connection between the existing hydraulic disc brake oil pipe and the pump body mostly adopts a screw locking method. During the assembly process, it is necessary to put the accessories on the oil pipe after the oil pipe is passed through and lock it into the pump body. If the oil pipe does not completely enter the pump body or the locking torque does not meet the requirements, it is easy to cause oil leakage. At the same time, the assembly process is also cumbersome, time-consuming and labor-intensive, and the efficiency is reduced. Utility Model Content
