A limiting ring 11 is fixedly connected to the side end of the hose body 1, a limiting groove 21 is opened at the side end of the connecting pipe body 2, and the limiting groove 21 is adapted to the limiting ring 11. A plug - in pipe 12 is fixedly connected to one side end of the inner wall of the hose body 1 near the limiting ring 11. A second bracket 4 is fixedly connected to the outer circle of the hose body 1 near one side. A plug shaft 41 is fixedly connected to the center of the top of the second bracket 4. A limiting plate 42 is slidably connected to the outer circle of the plug shaft 41. A first bolt 45 is rotationally connected by threading inside the limiting plate 42 near the center of the other side. A first bracket 3 is fixedly connected to the outer circle of the connecting pipe body 2 near one side. A first threaded hole is opened at the center of the top of the first bracket 3, and the first threaded hole is adapted to the first bolt 45.

[0021] External threads 43 are provided on the outer circle of the plug shaft 41 near the top.

[0022] By adopting the above - mentioned technical solution, external threads 43 are provided on the outer circle of the plug shaft 41 to threadedly rotate and install a nut 44.

[0023] A nut 44 is threadedly rotatably connected to the outer circle of the plug shaft 41 at the position of the external threads 43.

[0024] By adopting the above - mentioned technical solution, a nut 44 is provided at the position of the external threads 43 on the outer circle of the plug shaft 41 to limit the limiting plate 42.

[0025] Reflective strips 31 are symmetrically and fixedly connected to both side ends of the first bracket 3 near the center.

[0026] By adopting the above - mentioned technical solution, reflective strips 31 are symmetrically arranged on both side ends of the first bracket 3 so that the first bracket 3 and the second bracket 4 can be conspicuous at night.

[0027] A dust cover 46 is provided between the tops of the first bracket 3 and the second bracket 4.

[0028] By adopting the above - mentioned technical solution, a dust cover 46 is provided above the first bracket 3 and the second bracket 4 to prevent concrete from damaging the first bolt 45 and the second bolt 48.

[0029] Side plates 47 are fixedly connected to both side ends of the dust cover 46 near the corners.

[0030] By adopting the above - mentioned technical solution, side plates 47 are symmetrically arranged on both side ends of the dust cover 46 to threadedly rotate and install a second bolt 48.

[0035] Working principle: When the device is in use, when it is necessary to connect the hose body 1 and the connecting pipe body 2, the hose body 1 is inserted into the side end of the connecting pipe body 2, so that the limiting ring 11 can be inserted into the limiting groove 21, and the outer wall of the insertion pipe 12 abuts against the inner wall of the connecting pipe body 2. Then, the first bolt 45 inside the limiting plate 42 is rotated so that it can be rotated by threads into the first bracket 3, and then the nut 44 is rotated, so that the limiting plate 42 on the outer ring of the limiting insertion shaft 41 is completed, preventing the limiting plate 42 from loosening above the first bracket 3 and the second bracket 4, thereby realizing the effect of connecting the hose body 1 and the connecting pipe body 2, and further solving the problem that there is a gap between the two flanges through bolts and flanges;

[0036] By rotating the second bolts 48 inside the two side plates 47 by threads to the tops of the first bracket 3 and the second bracket 4, the effect of limiting the dust cover 46 is realized, thus completing the work of installing the dust cover 46 above the first bracket 3 and the second bracket 4, thereby realizing the effect of protecting the limiting plate 42 and preventing the limiting plate 42 from breaking due to the influence of concrete.
