Automotive air conditioning systems are divided into high-pressure piping and low-pressure piping, and are an important part of air conditioning operation.

[0003] However, when existing air conditioning pipes are connected to their corresponding connectors, they are mostly fixed to the connectors by screwing on a locking mechanism installed at one end of the pipe. Over time, this can easily loosen, resulting in poor sealing and leakage, which affects the performance of the air conditioner. Furthermore, it is inconvenient to disassemble the air conditioning pipes later when they are fixed by the locking mechanism. Utility Model Content
