[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, the boss of one of the adjacent two pipe bodies is inserted into one end of the other pipe body close to the installation component, so that the outer side of the boss abuts against the inner wall of the pipe body, and one end of the pipe body on one side of the boss abuts against one end of the connecting ring and the sealing gasket. Through the threaded fit of a plurality of second installation screws with the rotating seat, the connecting ring and the sealing gasket, and at the same time the threaded fit of the second installation screws with the first installation threaded holes of the boss, the splicing installation process of the adjacent two pipe bodies is carried out. By sliding one end of the rotating seat into the annular groove of the pipe body, during the assembly process of the adjacent two pipe bodies, the rotating seat is rotated to enable the second installation screws to pass through the connecting ring and the sealing gasket and be threadedly fixedly connected to the first installation threaded holes of the boss, reducing the labor amount of rotating the pipe body to dock the installation parts.

[0019] Embodiment 1

[0020] Please refer to Figure 1 - Figure 2, A prestressed duct with an end plugging structure in the illustration, including a duct main body 1. One end of the duct main body 1 is rotatably connected to an installation assembly 2, and a boss 3 adapted to the installation assembly 2 is fixedly connected to the end of the duct main body 1 away from the installation assembly 2. A plugging plate 4 is arranged on the side of the boss 3 away from the duct main body 1, and an end cover 5 is arranged on one side of the plugging plate 4. The outside of the end cover 5 is fixedly installed on the outside of the duct main body 1 through a plurality of first installation screws 6.

[0021] In this embodiment, an annular clamping groove 301 adapted to be clamped with the plugging plate 4 is opened at the end of the boss 3 away from the duct main body 1, and the side of the end cover 5 close to the duct main body 1 is arranged in contact with one side of the plugging plate 4. A plurality of second installation threaded holes 501 threadedly matched with the first installation screws 6 are penetrated through the end cover 5 in the circumferential direction. The installation assembly 2 includes an annular rotating seat 21 with an L-shaped cross-section. An annular groove 101 is opened on the outside of the duct main body 1. One end of the rotating seat 21 is slidably connected to the annular groove 101 of the duct main body 1, and the other end of the rotating seat 21 is fixedly connected to a connecting ring 22 that slidably contacts one end of the duct main body 1. A sealing gasket 23 is fixedly arranged inside the connecting ring 22, and the sum of the thickness dimensions of the connecting ring 22 and the sealing gasket 23 is greater than the thickness dimension of the duct main body 1. A plurality of second installation screws 24 threadedly matched with the first installation threaded holes 302 are arranged on the outside of the rotating seat 21, and a plurality of through grooves threadedly adapted to the second installation screws 24 are penetrated through the rotating seat 21, the connecting ring 22, and the sealing gasket 23 at the same position.

[0022] Furthermore, the boss 3 of one of the two adjacent pipe bodies 1 is inserted into the end of the other pipe body 1 close to the mounting assembly 2, so that the outer side of the boss 3 abuts against the inner wall of the pipe body 1 and the end of the pipe body 1 on one side of the boss 3 abuts against the connecting ring 22 and one end of the sealing gasket 23, and the second mounting screws 24 are threadedly matched with the rotating seat 21, the connecting ring 22 and the sealing gasket 23, and the second mounting screws 24 are threadedly matched with the first mounting threaded hole 302 of the boss 3 to perform the splicing and installation process of the two adjacent pipe bodies 1, and the one end of the rotating seat 21 is slidably connected with the annular groove 101 of the pipe body 1, so that the second mounting screw 24 passes through the connecting ring 22 and the sealing gasket 23 during the assembly process of the two adjacent pipe bodies 1. The connecting ring 22 and the sealing gasket 23 are threadedly fixedly connected to the first mounting threaded hole 302 of the boss 3, thereby reducing the labor of rotating the pipe body 1 to connect the mounting parts. At the same time, the thickness of the connecting ring 22 and the sealing gasket 23 is set to be larger than the thickness of the pipe body 1, so that when the boss 3 is inserted into the inner wall of the pipe body 1, the outer side of the boss 3 can squeeze the sealing gasket 23, thereby ensuring the sealing of the connection part of the two adjacent pipe bodies 1. When one end of the pipe body 1 needs to be sealed, the sealing plate 4 is clamped with the clamping groove 301 of the boss 3, and the inner wall of the end cover 5 is abutted against one end of the sealing plate 4, and the end cover 5 is threadedly connected to the first mounting threaded hole 302 of the boss 3 through a plurality of first mounting screws 6 for sealing.

[0023] Working principle of the utility model: Insert the boss 3 of one of the adjacent two pipe bodies 1 into one end of the other pipe body 1 close to the mounting component 2, so that the outer side of the boss 3 abuts against the inner wall of the pipe body 1, and one end of the pipe body 1 on one side of the boss 3 abuts against one end of the connecting ring 22 and the gasket 23. Through the threaded fit of a plurality of second mounting screws 24 with the rotating seat 21, the connecting ring 22 and the gasket 23, and at the same time the threaded fit of the second mounting screw 24 with the first mounting threaded hole 302 of the boss 3, the splicing and installation process of the adjacent two pipe bodies 1 is carried out. By slidingly connecting one end of the rotating seat 21 with the annular groove 101 of the pipe body 1, thus during the assembly process of the adjacent two pipe bodies 1, by rotating the rotating seat 21, the second mounting screw 24 passes through the connecting ring 22 and the gasket 23 and is threadedly fixedly connected with the first mounting threaded hole 302 of the boss 3, reducing the labor amount of rotating the pipe body 1 to dock the installation part. At the same time, the thickness dimensions of the connecting ring 22 and the gasket 23 are set to be greater than the thickness dimension of the pipe body 1. Thus, when the boss 3 is inserted into the inner wall of the pipe body 1, the outer side of the boss 3 can extrude the gasket 23, thereby ensuring the sealing performance of the connecting part of the adjacent two pipe bodies 1. When one end of the pipe body 1 needs to be blocked, snap the blocking plate 4 into the snap groove 301 of the boss 3, and abut the inner wall of the end cover 5 against one end of the blocking plate 4. Threadedly connect the end cover 5 with the first mounting threaded hole 302 of the boss 3 through a plurality of first mounting screws 6, thereby carrying out the blocking.
