[0033] Working principle:

[0034] When using the utility model, when installing the pipeline of the automobile air-conditioning system, since the thickness of the pipeline at different positions is different, at this time, during installation, the installation plate 1 can be vertically inserted into the original installation position of the automobile. After it is installed, the pipeline with a large outer inner diameter is inserted into the first installation tube 3. After the pipeline is inserted, a flat-head screwdriver can be placed on the right side of the sealing ring 4 and smashed to the left. At this time, the sealing ring 4 is smashed towards the thickest end of the first connecting ring little by little until it contacts the fixing plate 2. After the sealing ring 4 is installed, the above action is repeated to install the installation ring 5 to the outside of the sealing ring 4. The external pipeline is stuck in it to facilitate its fixation. After installing one side, the second installation tube 1 with a different outer diameter is selected according to the inner diameter size of the other pipeline. 1. After selecting the second mounting tube 11 of suitable diameter, insert the second mounting tube 11 with the insertion tube 10 from right to left into the gap between the mounting plates 1. When inserting, align the insertion tube 10 with the mounting groove 7 provided on the mounting plate 1. The insertion tube 10 is tightly connected with the first mounting tube 3. Then, manually insert the mounting screw 13 from right to left into the mounting hole 14 provided on the fixing plate 8. Use an external tool to rotate the mounting screw 13 to fix it between the fixing plate 8 and the mounting plate 1. After the second mounting tube 11 is installed, another flexible pipe can be manually inserted from right to left into the outside of the second mounting tube 11. The pipes required for the automobile air conditioner can be installed. The problem of mismatched pipe transfer can also be solved.
