[0026] Please refer to Figures 1-6, the present utility model provides a technical solution for a water supply and drainage pipe connection device, including a connecting pipe 1 and two rotating rings 2. The two rotating rings 2 are rotatably connected to both ends of the connecting pipe 1. The connecting pipe 1 and the rotating rings 2 are connected and fixed through a clamping mechanism. An internal thread groove 5 is formed between the inner side of the rotating ring 2 and the connecting pipe 1. An annular member 6 is threadedly connected in the internal thread groove 5. An external thread 7 is provided on the circumferential outer surface of the annular member 6. The external thread 7 meshes with the internal thread groove 5. The annular member 6 is slidably connected to the connecting pipe 1. Guide grooves 9 are formed on both sides of the outer surface of the connecting pipe 1. Guide blocks 8 that cooperate with the guide grooves 9 are fixed to both sides of the end of the annular member 6. An annular groove 10 is formed between the inner side of the annular member 6 and the connecting pipe 1. A sealing gasket 11 is provided on the inner wall of the annular groove 10. The sealing gasket 11 is pressed between the annular groove 10 and the outer surface of the connecting pipe 1. One end of the annular member 6 penetrates to the outside of the rotating ring 2 and is connected to a water supply and drainage pipe 12. The end of the water supply and drainage pipe 12 is pressed against the end of the connecting pipe 1. A water conveyance hole 14 is formed inside the connecting pipe 1. The water conveyance hole 14 communicates with the two water supply and drainage pipes 12 on both sides; when the water supply and drainage pipe 12 is connected to the connecting pipe 1, at this time, the rotating ring 2 is rotated. The rotation of the rotating ring 2 drives the annular member 6 to be inserted into the docking space between the connecting pipe 1 and the rotating ring 2 through the threaded action of the internal thread groove 5 and the external thread 7 and the rotational limit of the guide block 8 and the guide groove 9. During the insertion process, the sealing gasket 11 inside the annular member 6 will seal and fill the gap between the annular member 6 and the connecting pipe 1 to form a sealed connection until the end of the connecting pipe 1 is pressed against the end of the water supply and drainage pipe 12.

[0027] Refer to Figures 5-6, the clamping mechanism includes a fixed block 15 fixed on the outer surface of the connecting pipe 1. An installation block 16 is provided on one side of the fixed block 15. A movable plate 17 is movably connected to the installation block 16. A limiting block 18 is fixed at the end of the movable plate 17. A sliding hole 13 is formed in the movable plate 17. A sliding block 19 is slidably connected to the movable plate 17. Through holes 21 and spring grooves 22 are formed on the outer surface of the fixed block 15. A clamping rod 20 is slidably connected in the through hole 21. The end of the clamping rod 20 is movably connected to the sliding block 19. A slider 23 is slidably connected inside the spring groove 22. One side of the slider 23 is fixed with a connecting rod 24. The end of the connecting rod 24 penetrates to the outside of the fixed block 15 and is slidably connected to the sliding hole 13. A spring 25 is sleeved on the outer surface of the connecting rod 24 and located between the slider 23 and the inner wall of the spring groove 22. The clamping mechanism further includes an annular plate 3 fixed on the outer surface of the rotating ring 2 and an annular sliding groove 4 formed on the connecting pipe 1. The annular plate 3 is rotatably connected inside the annular sliding groove 4. The through hole 21 communicates with the annular sliding groove 4. A clamping hole matching with the clamping rod 20 is formed on the annular plate 3. The clamping rod 20 penetrates through the through hole 21 into the annular sliding groove 4 and is clamped in the clamping hole to connect the connecting pipe 1 and the rotating ring 2 together; through the design of the clamping mechanism, before rotating the rotating ring 2, it is necessary to pull the movable plate 17 to rotate. The rotation of the movable plate 17 drives the clamping rod 20 to move through the sliding block 19, so that the end of the clamping rod 20 disengages from the annular sliding groove 4, and then the rotating ring 2 can be rotated. After the rotation is completed, the clamping hole on the annular plate 3 is docked with the clamping rod 20. At this time, release the movable plate 17. Under the action of the spring 25, the clamping rod 20 is inserted into the clamping hole to connect the connecting pipe 1 and the rotating ring 2 together.

[0028] During use, the annular member 6 at the end of the water supply and drainage pipe 12 is inserted into the docking space between the connecting pipe 1 and the rotating ring 2. Specifically: it is guided and docked through the guiding block 8 and the guiding groove 9. When inserting and docking, rotate the rotating ring 2. The rotation of the rotating ring 2 drives the annular member 6 to be inserted into the docking space between the connecting pipe 1 and the rotating ring 2 through the threaded action of the internal thread groove 5 and the external thread 7 plus the rotational limit of the guiding block 8 and the guiding groove 9. During the insertion process, the sealing gasket 11 inside the annular member 6 will seal and fill the gap between the annular member 6 and the connecting pipe 1 to form a sealed connection until the end of the connecting pipe 1 is pressed against the end of the water supply and drainage pipe 12.

[0029] Before rotating the rotating ring 2, it is necessary to pull the movable plate 17 to rotate. The rotation of the movable plate 17 drives the clamping rod 20 to move through the sliding block 19, so that the end of the clamping rod 20 disengages from the annular chute 4, and then the rotating ring 2 can be rotated. After the rotation is completed, the clamping hole on the annular plate 3 is docked with the clamping rod 20. At this time, release the movable plate 17, and under the action of the spring 25, the clamping rod 20 is snapped into the clamping hole to connect the connecting pipe 1 and the rotating ring 2 together.
