Description

Technical Field

[0001] The utility model belongs to the technical field of automobile pipe joints, in particular to a pipe joint with an anti-leakage structure. Background Art

[0002] In the use of automobiles, several groups of pipes are involved to transport media. After the media are transported, they play a corresponding role. Pipe joints are needed to connect some pipes. Most common pipe joints are connected to pipes through preset threads and other structures. The setting of the threads requires the assistance of special tools, which leads to the need for prerequisites for the connection of pipe joints in some scenarios. In addition, the sealing performance of a single threaded connection is poor. In the later stage of use, its sealing performance will gradually decrease, which may lead to leakage of the transported media. The leaked media will contaminate other related parts and may affect the normal use of other parts. In addition, the leaked media is inconvenient to clean up in the later stage, causing unnecessary trouble to the normal use of the car.

[0003] In summary, pipe joints with poor sealing performance have some problems during use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
