[0026] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] As Figure 1-6 shown, a water supply and drainage pipe anti-seepage device includes a connecting pipe 1, which is composed of an outer pipe 11 and an inner pipe 12. A connecting ring 13 is fixedly connected between the outer pipe 11 and the inner pipe 12. The connecting ring 13 is located in the middle of the outer pipe 11 and the inner pipe 12. Sealing rings 14 are provided on both sides of the connecting ring 13. The connection part of the water supply and drainage pipe is located on both sides of the connecting ring 13. Fasteners 2 for positioning the water supply and drainage pipe are provided at both ends of the connecting pipe 1. A connecting member 3 for adjusting and fixing the distance between the two fasteners 2 is connected between the two fasteners 2 and the outer pipe 11.

[0028] Adopting the technical solution of this embodiment, the connection heads of the water supply and drainage pipes are respectively located on both sides of the connection head. The water supply and drainage pipes are in interference connection with the sealing ring 14. The sealing ring 14 is made of rubber material and can deform.

[0029] Referring to Figure 2 : The inner sides of both ends of the inner pipe 12 gradually become thinner from the middle towards the direction away from the middle.

[0030] Both ends of the inner pipe 12 gradually become thinner towards the outer ends, which can reduce the resistance suffered when water flows through, thereby making the water flow through more smoothly.

[0031] Referring to Figure 1 and 3 -4: The fastener 2 is a hoop 21. The hoop 21 is composed of two connecting heads 211 and an arc-shaped hoop plate 212. The two connecting heads 211 are fixedly connected to the ends of the hoop plate 212. The hoop plate 212 has elasticity. The hoop plate 212 is in close fit with the water supply and drainage pipe. An adjusting member 22 is connected between the two connecting heads 211.

[0032] In this embodiment, the water supply and drainage pipe is fixed by the hoop 21, and the adjusting member 22 is used to adjust the distance between the two connectors 211. When the distance between the two connectors 211 is relatively close, the outer diameter of the hoop plate 212 decreases, thereby fixing the water supply and drainage pipe. Since the hoop plate 212 is in close contact with the water supply and drainage pipe, the force on the water supply and drainage pipe is uniform, and there will be no situation where the force is too large at one place. Therefore, the water supply and drainage pipe has a longer service life when it is fixed.

[0033] Refer to Figure 3 : The adjusting member 22 is a first screw 221, and a first nut 222 is threadedly connected to the end of the first screw 221. The end face of the first nut 222 is in close contact with the outside of the connector 211.

[0034] In this embodiment, the distance between the two connectors 211 is adjusted by rotating the first nut 222. The first nut 222 abuts against the outside of the connector 211. By rotating the first nut 222, the hoop plate 212 is in close contact with the water supply and drainage pipe. The closer the distance between the connectors 211, the smaller the arc radius formed by the hoop plate 212.

[0035] Refer to Figure 3 : The connecting member 3 includes a first connecting seat 31 fixedly connected to the hoop plate 212 and a second connecting seat 32 fixedly connected to the outer pipe 11. A second screw 33 is rotatably connected between the first connecting seat 31 and the second connecting seat 32. A second nut 34 is threadedly connected to the end of the second screw 33, and the second nut 34 is in close contact with the first connecting seat 31.

[0036] Refer to Figure 2-3 : The number of both the first nut 222 and the second nut 34 is two.

[0037] In this embodiment, the double-nut connection is used for anti-loosening connection to prevent the first nut 222 and the second nut 34 from loosening.

[0038] In this embodiment, the two hoops 21 are connected by the second screw 33. By rotating the second nut 34, the two hoops 21 are brought closer to each other. When the hoops 21 fix the water supply and drainage pipe, the two hoops 21 drive the water supply and drainage pipe to approach each other, so that the water supply and drainage pipe is in close contact with the sealing ring 14. When the device is in use, each component can be disassembled. By removing the first screw 22, the hoop 21 can directly wrap the connecting pipe 1, which is convenient for installation.

[0039] The above embodiments are only used to exemplarily illustrate the principles and effects of the present utility model, rather than to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
