At this time, the plurality of The heat insulation plate 13 will surround the exhaust pipe. At the same time, gaps of different widths will appear between the multiple heat insulation plates 13 due to the difference in exhaust pipe diameters. Then the hook 16 will be placed in a pair of adjacent slots 14, and the connecting rod 17 will pass through the gap between the adjacent clamping rods 1. Then the limit plate 18 will be installed in the middle of the connecting rod 17 and the limit plate 18 will be rotated to squeeze the side wall of the clamping rod 1. The pull plate 15 will pull the heat insulation plate 13 so that the multiple heat insulation plates 13 will not be easily separated from the side wall of the clamping rod 1, thereby utilizing multiple heat insulation plates 13 and the pull plate 15 to wrap and insulate the exhaust pipe. Through the above structure, the wrapping member can be installed on exhaust pipes of different diameters to insulate the exhaust pipe, thereby improving the scope of application of the device.

[0025] like Figures 1 to 5As shown, a plurality of heat insulation plates 13 are detachably installed with a ring 2 at one end away from the clamping rod 1; a heat insulation sleeve 21 is fixedly connected to the side wall of the ring 2; a plurality of connecting plates 22 are installed at the other end of the heat insulation sleeve 21; a fastening bolt 23 is threadedly connected to the middle part of the connecting plate 22; during operation, after the plurality of heat insulation plates 13 and the pull plate 15 are installed, the ring 2 is installed at the end part of the plurality of heat insulation plates 13, and then the heat insulation sleeve 21 is put on the outside of the plurality of heat insulation plates 13, and then the connecting plate 22 is crossed over the middle part of the clamping rod 1, and the fastening bolt 23 is rotated so that the end part of the fastening bolt 23 is against the side wall of the clamping rod 1, so that the connecting plate 22 is tightened, and the ring 2 will not be easily detached from the end part of the plurality of heat insulation plates 13, and the heat insulation sleeve 21 can be further isolated from the heat on the exhaust pipe surface. Through the above structure, the heat on the exhaust pipe surface can be further isolated, and the impact of heat dissipation on surrounding objects can be further reduced.

[0026] like Figures 1 to 5 As shown, the inner side walls of the clamping rod 1 and the heat insulation plate 13 are provided with multiple ventilation grooves 3; a through groove 31 is provided in the middle of the ring 2; a blocking net 32 ​​is fixedly connected to the side wall of the clamping rod 1; the blocking net 32 ​​is located at the end of the multiple ventilation grooves 3; during operation, when the vehicle is running, air will continuously enter through the ventilation grooves 3 in the middle of the multiple clamping rods 1 and flow out from the multiple through grooves 31, so that the flowing air can take away the heat from the surface of the exhaust pipe, and the setting of the multiple blocking nets 32 can reduce the occurrence of impurities entering the ventilation grooves 3 and causing blockage. Through the above structure, the surface of the exhaust pipe can be dissipated when the vehicle is driving, reducing the occurrence of excessive heating of the heat insulation plate 13 and the heat insulation sleeve 21.

[0027] like Figures 1 to 4 As shown, the side wall of the clamp rod 1 is detachably installed with a guide plate 4; the guide plate 4 is located between the multiple ventilation slots 3 and the outer wall of the clamp rod 1; when working, the guide plate 4 can be installed on the side wall of the clamp rod 1 according to the adequacy of the space around the exhaust pipe, so that when the vehicle is driving, the surrounding air is guided to the entrances of the multiple ventilation slots 3, and the air pressure at the entrances of the multiple ventilation slots 3 is increased, thereby increasing the ventilation volume of the ventilation slots 3 per unit time, and then improving the heat exchange effect between the flowing air inside the ventilation slots 3 and the exhaust pipe. Through the above structure, the heat dissipation effect of the exhaust pipe can be further improved, and the occurrence of excessive heating of the insulation plate 13 and the insulation sleeve 21 can be further reduced.

[0028] like Figures 1 to 5 As shown, a protective sleeve 5 is fixed to the middle of the insulation sleeve 21; the protective sleeve 5 is made of waterproof and wear-resistant material; through the above structure, the insulation sleeve 21 can be protected to reduce the occurrence of damage to the insulation sleeve 21 or water immersion on the surface, which leads to a decrease in the insulation effect.

[0029] like Figure 1As shown, a plurality of straps 6 are provided in the middle of the protective cover 5; the plurality of straps 6 are evenly distributed in the middle of the protective cover 5; when working, the plurality of straps 6 are used to tighten the middle of the heat insulating cover 21, thereby reducing the shaking of the middle of the heat insulating cover 21. Through the above structure, the loosening caused by the continuous shaking of the middle of the heat insulating cover 21 during the driving of the vehicle can be reduced.

[0031] During operation, firstly, multiple clamping rods 1 are evenly sleeved on the exhaust pipe, and then the cable ties 12 are adjusted to make the multiple clamping rods 1 squeeze the exhaust pipe so that the multiple clamping rods 1 will not move easily in the middle of the exhaust pipe, and then multiple heat insulation boards 13 are inserted into the side walls of the multiple clamping rods 1. At this time, the multiple heat insulation boards 13 will surround the exhaust pipe, and at the same time, gaps of different widths will appear between the multiple heat insulation boards 13 due to the difference in the diameter of the exhaust pipe, and then the hook 16 is placed in a pair of adjacent card slots 14, and the connecting rod 17 is passed through the gap between the adjacent clamping rods 1, and then the limiting The positioning plate 18 is installed in the middle of the connecting rod 17 and the limiting plate 18 is rotated to squeeze the side wall of the clamping rod 1. The pull plate 15 pulls the heat insulation board 13 so that the multiple heat insulation boards 13 will not be easily separated from the side wall of the clamping rod 1, thereby using the multiple heat insulation boards 13 and the pull plate 15 to wrap the exhaust pipe for heat insulation. After the multiple heat insulation boards 13 and the pull plate 15 are installed, the collar 2 is installed at the end of the multiple heat insulation boards 13, and then the heat insulation sleeve 21 is put on the outside of the multiple heat insulation boards 13, and then the connecting plate 22 is crossed over the clamping rod. The middle part of the rod 1 is tightened by rotating the fastening bolt 23 so that the end of the fastening bolt 23 is against the side wall of the clamping rod 1, thereby tightening the connecting plate 22 and preventing the collar 2 from easily detaching from the end of the multiple heat insulation plates 13. The heat insulation sleeve 21 can further isolate the heat on the surface of the exhaust pipe. When the vehicle is running, air will continuously enter through the ventilation slots 3 in the middle of the multiple clamping rods 1 and flow out from the multiple through slots 31, so that the flowing air can take away the heat from the surface of the exhaust pipe, and the setting of the multiple blocking nets 32 can reduce the heat from the exhaust pipe. To prevent the entry of solids into the ventilation slots 3 and cause blockage, the guide plate 4 can be installed on the side wall of the clamping rod 1 according to the adequacy of the space around the exhaust pipe. Thus, when the vehicle is driving, the surrounding air is guided to the entrances of the multiple ventilation slots 3, and the air pressure at the entrances of the multiple ventilation slots 3 is increased, thereby increasing the ventilation volume of the ventilation slots 3 per unit time, and further improving the heat exchange effect between the flowing air in the ventilation slots 3 and the exhaust pipe. Use multiple straps 6 to tighten the middle part of the insulation sleeve 21, so as to reduce the shaking of the middle part of the insulation sleeve 21.
