A butt joint boss 7 is fixedly installed by inlaying on the outer surface of the inner side of the first automotive air-conditioning pipeline assembly pipe 2. An external thread is formed on the outer surface of the side end of the butt joint boss 7. A first sealing ring 8 is bonded inside the butt joint boss 7.

The second sealing ring 10 is in sealing fit with the first sealing ring 8. An internally threaded connection ring 11 is rotatably connected to the outer side of the upper end of the butt joint groove 9 through a rotating shaft, and the internally threaded connection ring 11 is threadedly connected to the outer surface of the side end of the butt joint boss 7, so that the butt joint boss 7 is locked and limited by the internally threaded connection ring 11;

[0027] Four through installation holes 12 are formed at the four corners of the installation base plate 1, and the number of the installation holes 12 is four, which are symmetrically distributed at the four corners of the installation base plate 1, so that the installation base plate 1 is fixedly installed inside the vehicle through the installation holes 12 in cooperation with installation bolts. A support column 13 is fixedly installed in the middle of the upper end surface of the installation base plate 1. An upper arc-shaped buckle 15 is hinged to the side end of the lower arc-shaped buckle 14 at the upper end of the support column 13, and the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are respectively surrounded inside the lower arc-shaped buckle 14 and the upper arc-shaped buckle 15.

[0028] Working principle: During use, the utility model can effectively resist the erosion of corrosive substances in the coolant, refrigerant, and external environment through the chemical corrosion resistance of the corrosion-resistant inner layer 5. The overall strength and compressive performance of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are improved through the reinforcing layer 4. At the same time, the overall weight of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 is reduced through the structure grooves 22. The corrosion resistance and anti-aging ability of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are further enhanced through the anti-corrosion coating sprayed on the outer curved surfaces of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3, while providing good wear resistance and weather resistance, thereby playing the role of high-reliability corrosion resistance for the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3;

[0029] At the same time, the mounting base plate 1 is fixedly installed inside the vehicle through the mounting holes 12 in cooperation with the mounting bolts. When the mounting base plate 1 is fixedly installed inside the vehicle, the lower arc-shaped buckle 14 and the upper arc-shaped buckle 15 are locked and limited through the mounting screw 17 in cooperation with the internally threaded mounting ring 16. When the lower arc-shaped buckle 14 and the upper arc-shaped buckle 15 are locked and limited, the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are limited and supported by the lower arc-shaped buckle 14 and the upper arc-shaped buckle 15, so that the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are fixed inside the vehicle. At the same time, the bottom of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 is supported by the arc-shaped support pad 18. When the bottom of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 is supported by the arc-shaped support pad 18, by opening the sealing plug 21, when the sealing plug 21 is opened, air is exhausted into the arc-shaped air cushion 19 through the air inlet pipe 20. When air is exhausted into the arc-shaped air cushion 19 through the air inlet pipe 20, the arc-shaped air cushion 19 expands and squeezes the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3, so that the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 are kept stable inside the lower arc-shaped buckle 14 and the upper arc-shaped buckle 15, thereby realizing the limitation and support of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3, and at the same time, the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 can be kept stable, avoiding the loosening of the first automotive air-conditioning pipeline assembly pipe 2 and the second automotive air-conditioning pipeline assembly pipe 3 caused by the long-term shaking of the vehicle.
