[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Reference Figures 1-2 The utility model provides an embodiment: a sealing connection structure of a building drainage pipe network, including first drainage pipe 1, first drainage pipe 1 right end is provided with second drainage pipe 2, first drainage pipe 1 with second drainage pipe 2 between being provided with first sealing pad 3, first drainage pipe 1 and second drainage pipe 2 outer wall both sides are provided with half sleeve 4, both sides half sleeve 4 front end both sides fixed connection's first fixed block 5, both sides first fixed block 5 between being connected through first bolt 6, half sleeve 4 inner side one end fixed connection's connecting block 8, connecting block 8 inner side one end all are fixedly connected with support plate 9, support plate 9 inner side one end all are fixedly connected with rubber pad 10, half sleeve 4 with first drainage pipe 1 and second drainage pipe 2 between being provided with second sealing pad 7;

[0025] Specifically, first, the first drain pipe 1 and the second drain pipe 2 are connected, and the first sealing gasket 3 is located between the two. Then, the half sleeve 4 is sleeved on the outer wall of the two drain pipes, and the second sealing gasket 7 is located between the half sleeve 4 and the drain pipe to enhance the sealing performance. Then rotate the first bolt 6 to move it inward and drive the first fixed block 5 to fix the two half sleeves 4. At this time, the connecting block 8 in the half sleeve 4 pushes the support plate 9 and the rubber pad 10 to move inward until the rubber pad 10 is tightly attached to the outer wall of the drain pipe, further improving the sealing performance of the connection.

[0026] With reference to Figure 1 and Figure 3 , the outer wall of the first drain pipe 1 and the second drain pipe 2 is provided with a fixed ring 11 on both sides, and the second fixed block 12 is fixedly connected at both ends of the two fixed rings 11. The two second fixed blocks 12 are connected by the second bolt 13, and the connecting plate 14 is fixedly connected at the front and rear ends of the fixed ring 11. The sleeve rod 15 is fixedly connected to the inner wall of the right connecting plate 14, and the screw rod 16 is rotatably connected to the inner wall of the left connecting plate 14. The knob 17 is fixedly connected to the left end of the screw rod 16, and the screw rod 16 is threadedly connected to the inner wall of the sleeve rod 15 at the right end.

[0027] Specifically, the second bolt 13 is tightened, which will push the second fixed block 12 to move and fix the two fixed rings 11. Then rotate the knob 17, which will make the screw rod 16 move to the right and fix the two connecting plates 14, ensuring the stability of the device and preventing the first drain pipe 1 and the second drain pipe 2 from loosening due to water flow impact.

[0028] Working principle: in use, the user first abuts the first drain pipe 1 and the second drain pipe 2, so that the first sealing gasket 3 is located between the first drain pipe 1 and the second drain pipe 2, then the half sleeve 4 is sleeved on the outer wall of the first drain pipe 1 and the second drain pipe 2, at this time the second sealing gasket 7 is located between the half sleeve 4 and the first drain pipe 1 and the second drain pipe 2, which increases the sealing performance, then rotate the first bolt 6, the first bolt 6 moves inward during rotation, the first bolt 6 drives the two first fixed blocks 5 to move, until the two half sleeves 4 are fixed, at this time the connecting block 8 in the half sleeve 4 drives the supporting plate 9 and the rubber pad 10 to move inward, until the rubber pad 10 is attached to the outer wall of the first drain pipe 1 and the second drain pipe 2, increasing the sealing performance of the connection between the first drain pipe 1 and the second drain pipe 2, then rotate the second bolt 13, the second bolt 13 moves inward during rotation, the second bolt 13 drives the two second fixed blocks 12 to move, until the two fixed rings 11 are fixed, then rotate the knob 17, the knob 17 rotates the screw rod 16, since the outer wall of the screw rod 16 is threadedly connected to the inner wall of the sleeve rod 15, so the screw rod 16 moves to the right during rotation, until the left connecting plate 14 is fixed with the right connecting plate 14, thereby completing the fixation of the whole device, preventing loosening between the first drain pipe 1 and the second drain pipe 2 due to the impact of water flow in the pipe during use.
