Background When the brake system is installed on the inner wiring bicycle, a high-pressure oil pipe connected with the oil brake upper pump/brake lower pump needs to penetrate through the inside of the bicycle frame and is connected with the oil brake upper pump/brake lower pump at the other end. Because the brake oil is filled in the oil pipe in advance, the joint parts of the oil pipes at the two ends can be sealed. The common sealing mode is surface sealing, and the installation of the oil pipe joint after the oil pipe penetrates through the frame generally requires a spanner to be matched with a locking oil pipe joint screw so as to deform internal parts to form sealing. However, the oil pipe quick-connection sealing mode requires a spanner to apply set torque force, and oil leakage risks exist when the torque force is insufficient, so that time and labor are wasted. Some oil pipe joints and oil pipe joint products of oil brake upper pump/brake lower pump rotation fast-assembling also appear in the market at present, but when these products are assembled, need to open the seal of oil circuit earlier and connect soon again, lead to probably getting into the air in the oil circuit, influence brake performance.
