Description

Quick release joint

This creation is related to the joints of the pipeline, in particular to a quick release joint.

According to the general oil line pipe, it can be used, for example, in a hydraulic brake system for bicycles, and is usually directly connected to the brake device, but in order to achieve more convenient and quick disassembly, the system further utilizes the push. The method of resisting the ball and the card slot are mutually engaged for quick release fixing.

In the conventional structure, the switching between the ball and the card slot is mainly through the push-pull of an outer sleeve for the assembly or release of the oil pipe. However, since the outer sleeve is only fixed by a spring member, it is extremely easy Due to the elastic fatigue of the spring, the fixing effect is lost and the tubing is loosened. In addition, the outer sleeve is also liable to cause the oil pipe to fall off due to an unintentional force pushing and pulling, resulting in serious consequences such as oil leakage and failure of the brake device, and further As disclosed in M466864, although the screw is used to avoid the loosening of the tubing, the working time of the screw lock is too long, and the screw lock may not be tightened and failed without proper tool assistance. Creation is a way to improve how to prevent the above problems.

Therefore, it is necessary to provide a novel and progressive quick release joint to solve the above problems.

The main purpose of this creation is to provide a quick release joint that is attached to the male connector and the female connector. Adding a necessary unlocking action before the joint is separated, compared with the conventional technology, a safety protection action is taken to prevent the risk of accidental loosening with the female connector, and is safe and stable for use in the fluid system, and when the male connector is When the female joint is separated, the fluid seal can be separately generated without leaking, and the use is clean and convenient.
