[0032] Further as Figure 5As shown, it is worth noting that the limiting device 10 includes a symmetrical first fixing plate 1001 or a second fixing plate 1002.

The limiting plate 1003 is slidably connected to the middle of the second fixing plate 1002, and one side of the limiting plate 1003 is slidably connected to a limiting groove 2041 provided on one side of the positioning post 204.

[0033] Further as shown in the figure Figure 1 and Figure 2 As shown, it is worth noting that the reinforcing ribs 5 are spiral or annular and are evenly distributed on the outer surface of the ventilation pipe body 1. The sealing ring 3 has a certain elasticity and is made of silicone. The reinforcing ribs 5 set on the outer surface of the ventilation pipe 1 enhance the overall strength and deformation resistance of the pipe body, making the ventilation pipe 1 less prone to deformation or damage during long-term use, thus extending its service life. In addition, the elastic sealing ring 3 is made of silicone and has the characteristics of high temperature resistance and aging resistance.

[0034] This solution has the following working process: Through the comprehensive design of the connecting flange 2, sealing ring 3, positioning column 204, reinforcing rib 5, snap-fit ​​structure 6, noise reduction layer 8, anti-corrosion coating 9 and heat insulation layer 7, this utility model realizes the functions of rapid connection, efficient sealing, high-strength support, rapid disassembly and assembly, noise reduction, corrosion prevention and heat insulation of the ventilation pipe 1, which significantly improves the installation efficiency, performance and service life of the ventilation pipe, and is suitable for ventilation ducts of various large air conditioning systems.

[0035] As can be seen from the above working process: by setting the positioning column 204 and the corresponding positioning hole 202 of the docking flange 2, the various pipe sections of the ventilation pipe can be quickly and accurately aligned during installation, reducing installation time and difficulty and improving construction efficiency. The elastic sealing ring 3 is made of silicone, which has the characteristics of high temperature resistance and aging resistance. The reinforcing ribs set on the outer surface of the ventilation pipe 1 enhance the overall strength and deformation resistance of the pipe body, making the ventilation pipe 1 less prone to deformation or damage during long-term use and extending its service life. The limiting plate 1003 of the limiting device 10 is slidably connected to the limiting groove 2041 on one side of the positioning column 204, which can automatically fix the positioning column 204, thereby facilitating the subsequent installation of the coupling 4.

[0036] Further as Figure 3As shown, it is worth noting that the inner surface of the ventilation duct body 1 is provided with a noise reduction layer 8, which is a porous sound-absorbing material used to reduce airflow noise in the ventilation duct.

[0037] Further as Figure 3 As shown, it is worth noting that the inner surface of the noise reduction layer 8 is coated with an anti-corrosion coating 9, which is an epoxy resin coating with a thickness of 0.1-0.3mm. The anti-corrosion coating 9 on the inner surface of the ventilation duct 1 can effectively resist the erosion of humid environments and corrosive gases, further extending the service life of the ventilation duct and reducing maintenance costs.

[0038] Further as Figure 1 and Figure 2 As shown, it is worth noting that the outer surface of the ventilation duct body 1 is provided with a heat insulation layer 7, which is made of glass wool or polyurethane foam material, to reduce the heat loss of the ventilation duct 1.

[0039] Further as Figure 1 and Figure 2 As shown, it is worth noting that each snap-fit ​​structure 6 includes a fixing ring 601. Each fixing ring 601 has a slot 602 in the middle of its outer surface. Each slot 602 has a movable ring 603 slidably connected inside it. Each movable ring 603 has several raised guides 604 evenly fixedly connected to its outer surface. Each raised guide 604 has a connecting hole 6041 in the middle. The connecting holes 6041 of the raised guides 604 of adjacent pipe sections can be fixedly connected by a connecting rope 605. By setting the snap-fit ​​structure 6, quick disassembly and assembly can be achieved between pipe sections, which is convenient for maintenance and replacement, reduces downtime, and improves the flexibility of use.

A rubber pad 406 is slidably connected to the outer surface of the other end of the fixed shaft 402, and a nut 405 is threadedly connected to it. The first spring 404 of the coupling 4 compensates for the relative displacement between the two shafts, providing buffering and vibration damping effects. This makes the ventilation pipe 1 less prone to deformation or damage during long-term use, extending its service life.

[0041] In summary, this utility model, through the integrated design of the connecting flange 2, sealing ring 3, positioning post 204, reinforcing rib 5, snap-fit ​​structure 6, noise reduction layer 8, anti-corrosion coating 9, and heat insulation layer 7, achieves functions such as rapid connection, efficient sealing, high-strength support, quick assembly and disassembly, noise reduction, corrosion prevention, and heat insulation for the ventilation duct 1. This significantly improves the installation efficiency, performance, and service life of the ventilation duct, making it suitable for ventilation ducts in various large-scale air conditioning systems. The noise reduction layer, made of porous sound-absorbing material, reduces airflow noise within the ventilation duct. The inner surface of the ventilation duct 1 is coated with an anti-corrosion coating 9. It can effectively resist the erosion of humid environments and corrosive gases, further extending the service life of the ventilation duct and reducing maintenance costs. The heat insulation layer 7 is made of glass wool or polyurethane foam to reduce heat loss of the ventilation duct 1. The snap-fit ​​structure 6 allows for quick disassembly and assembly between duct sections, facilitating maintenance and replacement, reducing downtime, and improving operational flexibility.
