[0002] Automobile air conditioning pipelines are pipelines that connect automobile air conditioning system components (such as pipelines connecting compressors, condensers, etc.), which contain hard pipes and soft pipes, and play the role of transmitting pipeline pressure and preventing vibration. Since the soft pipe is a rubber part, it is forbidden to age at high temperature and wear due to interference.

The air conditioning pipe joint is a threaded connection, and the assembly method is related to assembly experience. If the air conditioning pipe of the finished vehicle has insufficient clearance with the surrounding parts and may cause interference and other risks, it needs to be assembled and adjusted, which not only increases the adjustment time but also causes great loss of air conditioning refrigerant. In view of this, this application is specially proposed. Utility Model Content
