[0021] The following is combined with Figures 1-4 This application is described in further detail.

[0022] Example 1

[0023] Reference Figures 1-4, a duct interface conversion structure, including a folding tube 1, both ends of the folding tube 1 are thermoformed with connecting tube seats 2, one end of the two connecting tube seats 2 are thermoformed with a docking screw 3, the inside of the folding tube 1 is connected with an inner tube 4 in the middle of the two connecting tube seats 2, in order to reduce the noise and wind resistance caused by the folding lines on the inside of the folding tube 1 when the wind passes through the folding tube 1, the two ends of the inner tube 4 are respectively connected to the inner surface of the two connecting tube seats 2, and square docking tubes 5 are provided at both ends of the folding tube 1. A connecting groove 6 is opened at one end of the two square docking tubes 5, and a fitting piece 7 is slidably embedded in the inner side of the connecting groove 6. A circular docking tube 8 is welded to the outside of one end of the fitting piece 7. In order to dock and fix the circular docking tube with the square docking tube, a docking is opened at one end of the circular docking tube 8. Screw mouth 9, two docking screw tubes 3 are respectively engaged with the docking screw mouth 9 opened at one end of the two circular docking tubes 8. In order to make the folding tube 1 able to be replaced, the four corners of the outer side of the square docking tube 5 are welded with fixing ears 10, and the inner surface of the square docking tube 5 is welded with a number of docking blocks 11. A number of docking holes 13 provided on the surface of one end of a mosaic piece 7 respectively correspond to the number of docking blocks 11 welded on the inner side of the square docking tube 5 corresponding to the mosaic piece 7. The inner sides of the several docking blocks 11 are spirally connected with fixed limit bolts 12. The inner diameter of the docking hole 13 is the same as the outer diameter of the fixed limit bolt 12. The outer surfaces of the several mosaic pieces 7 are penetrated with docking holes 13, and the four corners of the outer sides of the two square docking tubes 5 are welded with docking holes 13.

[0024] Working principle: First, when the operator is in use, he first determines the docking conditions of the two ends of the docking according to the specific situation and adjusts the docking mechanism. If the two ends of the docking are round and square respectively, the operator needs to remove a square docking tube 5 of the docking mechanism. First, the operator loosens the several fixed limit bolts 12 that fix one end of the square docking tube 5 to the round docking tube 8, and takes out the several fixed limit bolts 12 from the embedded ends of the several docking blocks 11 welded on the inner side of one end of the square docking tube 5. Then, the engaging piece 7 welded on the outer side of one end of the round docking tube 8 is taken out from the inside of the connecting groove 6 opened at one end of the square docking tube 5. At this time, the state of the docking mechanism is that one end is a square docking tube 5 and the other end is a round docking tube 8. In this way, two connecting pipes that do not require docking interfaces can be docked, and fixed with bolts through the docking hole 13 opened on the surface of the engaging piece 7 welded on the outer side of one end of the round docking tube 8;

[0025] The square butt-jointing tube 5 can be fixedly connected to the corresponding connecting tube by means of the fixing ears 10 welded at the four corners of its outer sides. During the docking, the folding tube 1 can adjust the positions of the two connecting tubes without direct correspondence, and change the orientation of the square butt-jointing tube 5 and the circular butt-jointing tube 8 connected to it by folding and bending itself. The inner tube 4 connected inside the folding tube 1 can avoid the wind resistance caused by the folding lines inside the folding tube 1 when the wind passes directly through, and can also reduce the noise generated during the period. If the folding tube 1 or the inner tube 4 is damaged during the period, it can also be replaced. It is only necessary to remove the thermoplastic docking screws 3 at both ends of the folding tube 1 from the docking screw port 9 opened at one end of the circular butt-jointing tube 8, and then complete the connection of the new folding tube 1. This design can make the docking mechanism more practical.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
