[0022] Please refer to Figure 3 And Figure 5 Reinforcing mechanism 7 includes first air bag 13, first air bag 13 is arranged in the inner chamber of shell 6, the front side of first air bag 13 is communicated with second air bag 14, the inner chamber of second air bag 14 is provided with anti -skid convex 15, by setting first air bag 13, second air bag 14 and anti -skid convex 15, the movement of auxiliary rod 4 can be hindered, thereby play the effect of anti -loosening, and auxiliary rod 4 is located in the inner chamber of second air bag 14.

[0023] Please refer to Figure 1 , Figure 2 And Figure 4The sealing mechanism 10 includes an auxiliary groove 16, which is opened in the inner cavity of the first sealing gasket 9. A first rectangular airbag 17 is provided on the opposite side of the first sealing gasket 9. The top of the first rectangular airbag 17 is connected to the first air pipe 18. By providing the first rectangular airbag 17, the bus duct body 1 and the fixed plate 3 can be made tighter, and at the same time, the convex bag 19 is expanded to improve the sealing effect. The surface of the first rectangular airbag 17 is connected to the convex bag 19. By providing the convex bag 19, the first sealing gasket 9 can be expanded, thereby achieving a better sealing effect. The convex bag 19 is located in the inner cavity of the auxiliary groove 16.

[0024] See also Figure 1 、 Figure 2 and Figure 3 The top of the second rectangular airbag 11 is connected to the second air pipe 20. By setting the second rectangular airbag 11 and the second air pipe 20, the bus duct body 1 can be pushed toward the outside of the connecting frame 2 during separation, thereby facilitating the process of separating the bus duct. The top of the second air pipe 20 passes through the connecting frame 2.

[0025] See also Figure 2 and Figure 3 A mounting plate is fixedly connected to the opposite side of the second rectangular airbag 11. By setting the mounting plate, the second rectangular airbag 11 can be fixed, which is beneficial to the process of pushing the bus duct body 1. The mounting plate is fixedly connected to the rear side of the inner cavity of the connecting frame 2.

[0026] See also Figure 1 and Figure 2 The four corners of the front side of the fixing plate 3 are provided with connection holes 21. By providing the connection holes 21 and the fixing plate 3, the front side of the connection frame 2 can be closed, thereby improving the connection stability. The number of the second sealing gaskets 12 is four.

[0027] During use, the operator inserts the bus duct body 1 into the connecting frame 2, and makes the end of the auxiliary rod 4 be located on the opposite side of the shell 6, and the rod body of the auxiliary rod 4 is inserted into the inner cavity of the second air bag 14, and then uses the connecting frame 8 to connect the wire block of the bus duct body 1, and then screws the bolt into the connecting hole 21, so that the fixing plate 3 is fixed to the front side of the connecting frame 2. The first sealing gasket 9 and the second sealing gasket 12 can fill the gap between the bus duct body 1 and the connecting frame 2, and inflate the first air pipe 18 to make the first rectangular air bag 17 expand, and at the same time the convex bag 19 expands, which then increases the volume of the first sealing gasket 9, and at the same time cooperates with the first rectangular air bag 17 to squeeze the bus duct body 1, further improving the sealing effect of the first sealing gasket 9. When the connection becomes loose, the bus duct body 1 generates a The auxiliary rod 4 has a tendency to move in the opposite direction, so that the auxiliary rod 4 squeezes the first air bag 13, and the first air bag 13 shrinks, thereby causing the second air bag 14 connected to it to expand, and the anti-slip protrusion 15 also forms a force inward, and the anti-slip protrusion 15 is closer to the auxiliary rod 4, thereby increasing the friction force, hindering the movement between the bus duct body 1, and playing an anti-loosening role. When releasing the connection, the fixing plate 3 is removed by bolts, the connecting frame 8 is loosened, and the first air pipe 18 is inflated to make the first rectangular air bag 17 expand, thereby pushing the bus duct body 1 to the front side, and then the second cylinder is inflated to make the second rectangular air bag 11 expand, pushing the bus duct body 1 in the opposite direction, thereby saving the operator's physical strength and bringing convenience to the process of removing the bus duct body 1.

[0028] To sum up: the bus duct connection device with sealing function solves the problem that it usually does not have the advantage of being able to further improve the sealing effect and the problem that the connection is easy to loosen through the cooperation of the connecting frame 2, the fixing plate 3, the first sealing gasket 9, the second sealing gasket 12, the first airbag 13, the second airbag 14, the anti-slip protrusion 15, the auxiliary groove 16, the first rectangular airbag 17, the first air pipe 18, the convex bag 19, the auxiliary rod 4, the connecting rod 5 and the shell 6.
