[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Such as Figures 1 - 4As shown in the figure, the utility model provides a technical solution: a air duct fabric with a base surface bonding structure, which includes an air duct fabric main body 1. A bonding mechanism 2 is arranged on the outer wall of the air duct fabric main body 1, and an interface mechanism 3 is arranged at the end of the air duct fabric main body 1. The bonding mechanism 2 includes a metal support ring 21, which is fixedly sleeved on the outer wall of the air duct fabric main body 1. A spacer 22 is fixedly installed on the side of the metal support ring 21. One side of the spacer 22 away from the metal support ring 21 is movably connected with a movable strip 23. One side of the movable strip 23 away from the spacer 22 is fixedly connected with a magic tape 24. The inner surface and the outer surface of the air duct fabric main body 1 are both coated with a flame retardant coating 11. One side of the flame retardant coating 11 away from the air duct fabric main body 1 is fixedly connected with a metal fiber layer 12. The end of the metal fiber layer 12 is fixedly connected with the side of the metal support ring 21. The magic tape 24 can stick the sides of two adjacent metal support rings 21 together, and at the same time, the air duct fabric main body 1 is received into the hollow inner cavity formed by the spacer 22, improving the convenience and neatness of storing the air duct fabric main body 1. The material of the flame retardant coating 11 is set as aluminum hydroxide. The flame retardant coating 11 has a flame retardant effect and a gas phase effect, which is used for flame retardant protection of the air duct fabric main body 1. Aluminum hydroxide will decompose and release water and gas under high temperature for flame retardant. Through the design of the metal fiber layer 12, the anti-tearing ability of the air duct fabric main body 1 is improved. The metal fiber layer 12 can guide the static electricity on the air duct fabric main body 1 to the metal support ring 21, and then conduct it to the ground through an external wire to achieve the function of anti-static electricity.

[0025] As an implementation manner in this embodiment, as Figure 3 shown, one side of the movable strip 23 close to the spacer 22 is fixedly connected with a plugging rod 25. A groove 26 is formed on the outer surface of the plugging rod 25. A threaded rod 27 is threadedly connected to the outer wall of the spacer 22. The threaded end of the threaded rod 27 is rotatably connected with a circular limiting block 28. The circular limiting block 28 is movably inserted into the inner cavity of the groove 26. Manually rotate the threaded rod 27 to make the circular limiting block 28 withdraw from the inside of the groove 26, and then the movable strip 23 can be replaced. After the new movable strip 23 is reset and inserted, rotate the threaded rod 27 again to make the circular limiting block 28 move into the inner cavity of the groove 26 to complete the locking of the movable strip 23. Thus, the damaged magic tape 24 can be replaced, improving the service life of the bonding function of this structure.

[0026] As an implementation manner in this embodiment, as Figure 5 、 Figure 6 、 Figure 7As shown in the figure, the interface mechanism 3 includes a connecting cylinder 31. A rubber outer cylinder 33 is fixedly connected to the right side of the connecting cylinder 31. An inner cylinder 32 located in the inner cavity of the rubber outer cylinder 33 is fixedly connected to the right side of the connecting cylinder 31. The outer wall of the main body 1 of the air duct cloth is movably connected to the inner wall of the rubber outer cylinder 33, and the inner wall of the main body 1 of the air duct cloth is movably connected to the outer wall of the inner cylinder 32. A partition ring 311 is fixedly installed on the inner wall of the connecting cylinder 31. A filter cylinder 312 is fixedly installed on the right side of the partition ring 311. A raised block 34 is fixedly installed on the outer wall of the connecting cylinder 31. A nylon belt 341 is fixedly connected to the back of the raised block 34. A through groove 342 is formed on the front surface of the raised block 34. The nylon belt 341 is movably inserted into the inner cavity of the through groove 342. A fixing bolt 343 is threadedly connected to the top of the raised block 34. The threaded end of the fixing bolt 343 is movably connected to the outer wall of the nylon belt 341. The end of the main body 1 of the air duct cloth is inserted into the inner cavities of the inner cylinder 32 and the rubber outer cylinder 33. Then, the nylon belt 341 is pulled in the inner cavity of the through groove 342, and then the fixing bolt 343 is rotated to position the nylon belt 341, so as to position the main body 1 of the air duct cloth in the inner cavities of the inner cylinder 32 and the rubber outer cylinder 33. Immediately afterwards, the end of the connecting cylinder 31 away from the main body 1 of the air duct cloth is connected to the air outlet end of the external device. Through the design of the filter cylinder 312, the air can be filtered, and the smoothness of the inner cavity of the main body 1 of the air duct cloth can be improved.

[0027] Working principle: When in use, the end of the main body 1 of the air duct cloth is inserted into the inner cavities of the inner cylinder 32 and the rubber outer cylinder 33. Then, the nylon belt 341 is pulled in the inner cavity of the through groove 342, and then the fixing bolt 343 is rotated to position the nylon belt 341, so as to position the main body 1 of the air duct cloth in the inner cavities of the inner cylinder 32 and the rubber outer cylinder 33. Immediately afterwards, the end of the connecting cylinder 31 away from the main body 1 of the air duct cloth is connected to the air outlet end of the external device, and then the air can be conveyed through the main body 1 of the air duct cloth. When storing, the sides of two adjacent metal support rings 21 can be adhered together through the magic tape 24, and at the same time, the main body 1 of the air duct cloth can be stored in the hollow inner cavity formed by the spacer 22.
