[0002] Composite ducting, represented by rubber-plastic composite ducting, is made from a rubber-plastic composite insulation material. It can completely replace traditional ducting, dampers, vents, static pressure boxes, and insulation materials in air conditioning delivery systems. The sheet material is mechanized for smooth, even surface, improving air delivery efficiency and reducing air leakage to just 10% of that of sheet metal ducting. During production, fabrication, installation, and use, these ducts produce no harmful substances, are rust-proof, mold-proof, or dust-free, and are free of the dust and fibers of fiberglass ducts. They also have a low thermal conductivity and excellent thermal insulation properties.

[0003] The air ducts in the existing technology are usually exhaust components. Compared with ordinary air ducts, their composite materials can effectively improve the air delivery efficiency and significantly reduce the air leakage rate. However, for places with special locations and complex structures, it is often necessary to customize special-shaped air ducts according to the size and specific shape of the place, which reduces the installation efficiency of the air ducts.

[0004] To this end, we designed a new type of composite air duct. Summary of the Invention

[0008] Preferably, the surface plate is provided with a metal skin for improving rigidity, and the surface plate is against the outer wall of the tube body.

[0009] Preferably, the first connecting strip is L-shaped and is fixedly connected to the tube body by a plurality of rivets. One end of the first connecting strip is fixedly connected to the skin plate by welding. The outer wall of the skin plate is provided with a second connecting strip and a third connecting strip for improving the connection effect of the tube body. The second connecting strip and the third connecting strip are fixedly connected to the tube body through fasteners passing through the skin plate.

[0010] Preferably, the sealing strip is U-shaped, and one end is fixedly connected to the skin plate by welding. A groove is formed at one end of the sealing strip, and the groove abuts against the top surface of the tube body.

[0011] Preferably, the fireproof material is rectangular and fixedly connected to the skin plate by fasteners, one end of the fireproof material is against the sealing strip, and one side of the fireproof material is against the outer wall of the tube body.

[0012] Preferably, the extension edge is fixedly connected to the sealing strip by welding, and a plurality of screw holes for splicing the pipe body are provided on the extension edge.

[0013] The beneficial effects of the utility model are:

[0014] The utility model arranges the first connecting strip and the second connecting strip so that the surface plate can be effectively and tightly connected to the tube body, and also improves the bonding effect between the surface plate and the outer wall of the tube body, reducing the damage to the outer wall of the tube body caused by the impact of the outer wall. At the same time, the first connecting strip and the second connecting strip can improve the convenience of connecting the surface plate and the tube body, and multiple rivets can prevent the surface plate from loosening due to vibration of the tube body. The third connecting strip can improve the stability of the surface plate on the tube body, and can improve the installation efficiency in places with complex structures.

[0015] The utility model provides an extended edge so that the pipe bodies can be butted against each other and are tightly connected according to the screw holes, thereby reducing the loosening of the connection caused by the vibration of the fan. The fireproof material can greatly improve the fire resistance of the pipe body, thereby preventing the pipe body from being affected by the fire and unable to work normally.
