Anti-slip rubber layers 202 are arranged around the inner walls of the sound insulation upper cover 200 and the sound insulation lower cover 200-1.

[0029] The arranged sound insulation upper cover 200 and sound insulation lower cover 200-1 wrap the composite air duct 100, and the sound insulation cavities 203 arranged inside the sound insulation upper cover 200 and sound insulation lower cover 200-1 can effectively reduce the sound when it is transmitted.

[0030] Embodiment 2

[0031] Please refer to Figure 1 and Figure 2 , Shock-absorbing support rods 400 are arranged on the upper end surfaces of both of the two connecting rod bodies 300, and the shock-absorbing support rods 400 are fixedly connected to the upper end surfaces of the connecting rod bodies 300. Installation fixing plates 401 are arranged on the upper end surfaces of the shock-absorbing support rods 400. Sound insulation cavities 203 are arranged inside both the sound insulation upper cover 200 and the sound insulation lower cover 200-1. Support rods 204 are arranged inside the sound insulation cavities 203.

[0032] The setting of the shock-absorbing support rods 400 can weaken the vibration caused by the wind force and make the overall equipment device more stable.

[0033] Please refer to Figure 1 and Figure 3 , Second reserved installation holes 304 are arranged inside the end faces of the two I-shaped connecting blocks 303. Moving cavities 301 are arranged inside the two connecting rod bodies 300, and the moving cavities 301 are integrally formed with the connecting rod bodies 300. First reserved installation holes 302 are arranged on both sides inside the moving cavities 301, and a plurality of first reserved installation holes 302 are provided.

[0034] The provision of the first reserved mounting hole 302 and the second reserved mounting hole 304 provides connection and fixing positions for the connection structure.

[0035] Please refer to Figure 4 and Figure 5 Inside the second reserved mounting hole 304, a bolt 305 is provided, and one end of the bolt 305 penetrates and extends into the inside of the first reserved mounting hole 302.

After installation, the snap block 206 on the sound insulation upper cover 200 is snap-connected to the sound insulation lower cover 200-1 to wrap the composite air duct 100. At the same time, the anti-slip rubber layer 202 on the inner walls of the sound insulation upper cover 200 and the sound insulation lower cover 200-1 increases the connection friction force for the composite air duct 100. The installation fixing plate 401 can fix the position of the connecting rod body 300. During the use of the air duct, the strong wind force will vibrate the composite air duct 100, and the shock-absorbing support rod 400 provided on the connecting rod body 300 maximally weakens the vibration during the transportation of the gas, so that the overall device can effectively weaken the noise pollution caused by the vibration frequency of the equipment operation;
