Description

Technical Field

[0002] The brake hoses currently sold on the market are all brake hose assemblies with joints. In addition to the pipe joints, the brake system is used to transmit or store the hydraulic pressure, air pressure or vacuum for automobile brake boosting. They are divided into rubber brake hoses and nylon brake hoses according to their materials. Rubber brake hoses have strong tensile strength and are easy to install. The disadvantage is that the surface is prone to aging after long-term use. If it is impacted by external force, it is easy to rupture. The connection method of the hose is generally wire bundling or pipe clamp connection. The common feature is that the bundled or clamped hose produces inward extrusion deformation, relying on the inner surface of the hose or the inner surface of the inner layer tube. The connection strength and sealing are not easy to guarantee, it is easy to leak or even fall off, and the loading and unloading operations are cumbersome. However, the hose connectors in the prior art have unstable fixation. Some of them need to be tightened in multiple directions to be more firmly fixed. For example, the utility model patent with patent announcement number CN210950330U fixes the hose connector by screwing multiple bolts, which is a cumbersome operation.
