[0023] Such as Figures 1-4As shown in the figure, the utility model provides a technical solution: a tear-resistant rubber air duct cloth, which includes a rubber air duct cloth main body 1. A strengthening mechanism 2 is arranged on the rubber air duct cloth main body 1, and a convenient splicing mechanism 3 is arranged at the end of the rubber air duct cloth main body 1. The strengthening mechanism 2 includes an alloy ring 21 and a polyurethane coating 212. The alloy ring 21 is fixedly connected to the middle of the rubber air duct cloth main body 1. Metal fiber wires 211 are fixedly connected to both sides of the alloy ring 21, and the metal fiber wires 211 are fixedly connected to the inside of the rubber air duct cloth main body 1. The polyurethane coating 212 is coated on the outer surface of the rubber air duct cloth main body 1. A conducting wire 214 is fixedly connected to the outer wall of the alloy ring 21. One end of the conducting wire 214 away from the alloy ring 21 is fixedly connected to an alloy block 216. A hidden groove 215 is formed on the outer surface of the alloy ring 21, and the alloy block 216 is movably connected to the inner cavity of the hidden groove 215. A first magnetic attraction block 217 is fixedly installed on the inner wall of the alloy block 216, and the outer wall of the first magnetic attraction block 217 is magnetically connected to the inner wall of the hidden groove 215. The polyurethane coating 212 can form a protective layer on the outer surface of the rubber air duct cloth main body 1, improving the strength, wear resistance and corrosion resistance on the outside of the rubber air duct cloth main body 1, and avoiding the problem that the rubber air duct cloth main body 1 is easily damaged during the position adjustment process. The metal fiber wires 211 are used to improve the anti-tensile performance of the rubber air duct cloth main body 1, avoiding the problem that the rubber air duct cloth main body 1 is easily damaged during the pulling process. The alloy block 216 is pre-inserted into the ground in advance. Through the cooperation of the alloy ring 21 and the metal fiber wires 211, the static electricity on the rubber air duct cloth main body 1 can be guided to the alloy block 216 through the conducting wire 214 and then introduced into the ground, realizing the function of removing static electricity and avoiding the problem that excessive charges accumulate on the rubber air duct cloth main body 1 to generate electric sparks. Through the design of the hidden groove 215, the operator can hide the alloy block 216 into the inside of the hidden groove 215. At the same time, due to the design of the first magnetic attraction block 217, it can magnetically connect the whole alloy block 216 in the inner cavity of the hidden groove 215, avoiding the problem that the alloy block 216 is in a scattered state during the movement of the rubber air duct cloth main body 1, which is likely to cause the conducting wire 214 to be broken.

The material of the smooth alloy rod 213 is set as carbon fiber. The cross-sectional diameter of the metal fiber wire 211 is set as 0.1 mm, and the thickness value of the polyurethane coating 212 is set as 0.5 mm. Through the design of the smooth alloy rod 213, the static electricity in the flowing air inside the rubber air duct cloth main body 1 can be absorbed and then guided to the alloy ring 21, improving the static electricity removal ability of this structure.

[0025] As an implementation manner in this embodiment, as Figure 1 、 Figure 5 、 Figure 6As shown in the figure, the convenient splicing mechanism 3 includes a first splicing ring member 31 and a second splicing ring member 32.

A rotating shaft 323 is rotatably connected to the outer wall of the inner side of the fixing block 322. A semi-ring connecting member 324 is fixedly installed on the outer wall of the rotating shaft 323. A clamping member 325 is fixedly installed at one end of the semi-ring connecting member 324 away from the rotating shaft 323. Pin slots are formed on both the plug-in plate 312 and the second splicing ring member 32. The clamping member 325 is movably inserted into the inner cavity of the pin slot. A second magnetic attraction block 326 is fixedly installed on the inner wall of the clamping member 325, and the outer wall of the second magnetic attraction block 326 is magnetically connected to the outer wall of the second splicing ring member 32. Insert the first splicing ring member 31 into the side of the second splicing ring member 32. Through the design of the rubber ring 311, the connection between the first splicing ring member 31 and the second splicing ring member 32 can be sealed. At the same time, the plug-in plate 312 is inserted into the inside of the plug-in slot 321. Then manually rotate the clamping member 325 so that the clamping member 325 is inserted into the inside of the pin slot. At the same time, the second magnetic attraction block 326 is magnetically connected to the outer wall of the second splicing ring member 32 to lock the position of the clamping member 325, that is, the connection between the first splicing ring member 31 and the second splicing ring member 32 is locked, realizing the function of convenient connection, and the overall laying efficiency of the rubber air duct cloth main body 1 can be improved.

[0026] Working principle: The polyurethane coating 212 is used to form a protective layer on the outer surface of the rubber air duct cloth main body 1 to improve the strength, wear resistance and corrosion resistance on the outside of the rubber air duct cloth main body 1. The metal fiber filaments 211 are used to improve the tensile resistance of the rubber air duct cloth main body 1. First, insert the alloy block 216 into the ground. Through the cooperation of the alloy ring 21 and the metal fiber filaments 211, the static electricity on the rubber air duct cloth main body 1 can be guided to the alloy block 216 through the wire 214 and then introduced into the ground, realizing the function of static electricity removal protection for the rubber air duct cloth main body 1.
