Connecting joint

Abstract

The invention belongs to the technical field of automobiles and discloses a connecting joint which comprises a connecting member body, a shackle and a docking portion. A first cavity is arranged inside the connecting member body, the docking portion is arranged at one end of the connecting member body, the first cavity is communicated with the inside of the docking portion, and the shackle is inserted into the first cavity along the radial direction of the connecting member body. By inserting the shackle into the first cavity along the radial direction of the connecting member body, the shackle and a boss on a male joint are enabled to be buckled, so that the male joint can be effectively fixed inside the connecting member body; the shackle and the connecting member body are enabled to be buckled, so that the shackle and the connecting member body can be firmly connected together, reliability in connection between the male joint and the connecting member body is further guaranteed, the circumstance that the male joint and the connecting joint are prone to disconnecting is avoided, leaking of inflammable substances like gasoline, diesel and lubricating oil in pipelines from the pipelines is avoided, and personal safety of personnel inside an automobile is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a connecting joint. Background technique [0002] The automobile oil circuit refers to the fuel system of the automobile. There are many pipes in the automobile oil circuit. These pipes are usually connected through connecting joints and male joints. One of the pipes is fixedly connected to the male joint, the other pipe is fixedly connected to the connecting joint, the male joint is plugged into the inside of the connecting joint, and the boss provided on the male joint is interlocked with the inside of the connecting joint. [0003] Existing connecting joints usually include a connector body, an oval elastic ring and a sealing ring, the oval elastic ring and the sealing ring are sequentially arranged inside the connector body, and the two ends of the long axis of the oval elastic ring respectively pass through the connector The side wall of the body extends to the outside....

AI Technical Summary

Problems solved by technology

[0005] In the prior art, during use, since the two ends of the long axis of the elliptical elastic ring are always located outside the connector body, it is very easy to contact the outside world and be pressed during use, so that the male joint withdraws from the connecting joint, resulting in The reliability of the connection between the male joint and the connecting joint is very poor. When the connection between the male joint and the connecting joint is disconnected, it will cause gasoline, diesel oil, lubricating oil and other flammable substances in the pipeline to leak from the pipeline. A serious threat to the personal safety of occupants inside the car
