[0002] When a car is running for a long time, the temperature of the car exhaust pipe will remain high. The car exhaust pipe needs to be insulated to avoid damaging other accessories. Currently, most exhaust pipe insulation uses a heat shield installed outside the exhaust pipe to surround the exhaust pipe. Generally, the heat shield is connected together by welding. Under long-term high temperature and bumpy working conditions, the welds are easy to fall off, resulting in an unstable connection between the heat shield and the exhaust pipe, which cannot play a heat insulation role. Therefore, a new fixing method is needed to fix the heat shield to the outer periphery of the exhaust pipe to ensure the stability of the heat shield during the bumpy driving of the car.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0018] As shown in the figure, a cable tie includes a cable tie body 1, which includes a tensioning portion 2 and a fixing portion 3. The tensioning portion 2 and the fixing portion 3 are respectively located at opposite ends of the cable tie body 1. The tensioning portion 2 is semi-fusiform, and the tensioning portion 2 includes a barb convex 21 and a barb slit 22. The cross-section of the barb slit 22 is an isosceles trapezoid. The barb convex 21 protrudes toward the outside of the cable tie body 1. The maximum height of the barb convex 21 is 0.9 mm. The length of the barb convex 21 is 6.75 mm, the width is 3.56 mm, and the tolerance of each dimension is ±0.1 mm. A barb gap 22 is formed between the barb convex bulge 21 and the cable tie body 1, and the barb gap 22 cooperates with the anti-backward mechanism to hook the barb convex bulge 21 and thus tighten the cable tie body 1; the fixing portion 3 includes a fixing convex bulge 1 31 and a fixing convex bulge 2 32, and the fixing convex bulge 1 31 and the fixing convex bulge 2 32 are also semi-shuttle-shaped, and the spike ends of the fixing convex bulge 1 31 and the fixing convex bulge 2 32 are located on opposite sides, and a fixing crossbeam 34 is provided between the fixing convex bulge 1 31 and the fixing convex bulge 2 32. The fixing portion 3 is also provided with a support member 33, and the support member 33 is clamped on the fixing convex bulge The support member 33 is located between the fixed convex 31 and the fixed convex 32, and the plane portion between the fixed convex 31 and the fixed convex 32 is parallel to the fixed crossbeam 34. The maximum height of the fixed convex 31 is 0.5mm, the length of the fixed convex 31 is 4.75mm, and the width is 4.52mm; the maximum height of the fixed convex 32 is 0.5mm, the length of the fixed convex 32 is 6.75mm, and the width is 3.56mm. The tolerance of each size is ±0.1mm. The support member 33 is provided with a groove 331 and a boss. 332, side 1 333, side 2 334. Both side 1 333 and side 2 334 are arc-shaped. The maximum distance between side 1 333 and side 2 334 in the width direction of the cable tie body 1 is the same as the width of the cable tie body 1. The height of the protrusion 332 is 1.35mm, and the depth of the recess 331 is 3mm. The tolerance of each dimension is ±0.1mm. This forms a structure in which both sides of the support member 33 embrace the cable tie body 1. The fixed protrusion 1 31 is inserted into the recess 331, and the fixed protrusion 2 32 abuts against the protrusion 332. This design is more secure because after the cable tie is tightened and pressed, the barbs formed will be stuck between the fixed crossbeam 34 and the protrusion 332. The support member 33 is fixed to the cable tie body 1 by the fixed protrusion 1 31 and the fixed protrusion 2 32, and the side 1 333 and the side 2 334 are stuck to the edge of the cable tie body 1. The cable tie of the utility model has high fixing strength and good effect. Since the cable tie of the present invention is used in an environment with relatively high temperature, stainless steel is preferably selected to ensure the fixing effect of the cable tie.

[0019] The above embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
