[0020] Example 1: Multi-layer environmentally friendly vehicle air conditioning pipe, see Figures 1 to 6 , including a tube body 1, a thermal insulation pad 2 is provided on the outside of the tube body 1, the thermal insulation pad 2 is wrapped around the outside of the tube body 1, one end of the thermal insulation pad 2 is fixedly connected to a fixing belt 4, a groove 42 is provided at the end of the thermal insulation pad 2 away from the fixing belt 4, the inner size of the groove 42 is adapted to the outer size of the fixing belt 4, and reinforcement mechanisms 3 are provided at both ends of the thermal insulation pad 2, and the reinforcement mechanisms 3 include hoop straps 34 installed at both ends of the thermal insulation pad 2, one end of the two hoop straps 34 are fixedly connected to a rectangular frame 32, the tops of the two rectangular frames 32 are fixedly connected to a fixing box 31, a worm 33 is rotatably connected between the two ends of the two fixing boxes 31, and a plurality of tooth grooves 35 are provided on the two hoop straps 34, The worm 33 and the tooth groove 35 are meshed with each other. When working, the heat insulation layer is wrapped around the outside of the pipe body 1 for heat insulation protection. At the same time, the fixing belt 4 is placed in the groove 42 to prevent the heat insulation layer from being wrapped around the outside of the pipe body 1 and leaving gaps that affect the heat insulation effect of the pipe body 1. One end of the hoop 34 is inserted into the rectangular groove, and then the worm 33 is twisted to cooperate with the tooth groove 35 to tighten the hoop 34, thereby increasing the firmness of the heat insulation layer installed on the outside of the pipe body 1. When the pipe body 1 is damaged, the hoop 34 is loosened by twisting the worm 33 to cooperate with the tooth groove 35, and then the hoop 34 is separated from the rectangular frame 32, and then the fixing belt 4 is pulled out from the groove 42, thereby facilitating the disassembly and assembly of the heat insulation layer on the outside of the pipe body 1, and thereby facilitating the reuse of the heat insulation layer.

[0021] For details, see Figure 5 Both ends of the fixing belt 4 are fixedly connected with hook-shaped Velcro 41, and the upper and lower sides of the inner cavity of the groove 42 are installed with velvet Velcro 43. When the fixing belt 4 is placed in the groove 42, the hook-shaped Velcro 41 and the velvet Velcro 43 adhere to each other, thereby improving the stability of the thermal insulation layer wrapped around the outside of the tube body 1.

[0022] For further information, see Figure 6The thermal insulation pad 2 includes an aluminum foil reflective layer 21, a polyurethane foam layer 22 and an outer protective layer 23.
