[0020] The following combines the drawings and embodiments to describe the present utility model in detail. Embodiment

[0021] A drainage pipeline, as Figure 1 and Figure 2As shown, it includes several pipe bodies 1. The pipe bodies 1 are fixed to each other through a connecting piece 2. Specifically, both ends of the connecting piece 2 are connected, the connecting piece 2 can be deformed, and the diameters of both ends of the connecting piece 2 are larger than the diameter of the pipe body 1. By setting the connecting piece 2 and connecting two pipe bodies 1 with the connecting piece 2, during the drainage process of the drainage pipe, the connecting piece 2 can play a role in connecting and passing water. Since the connecting piece 2 can be deformed, when the installation terrain is uneven, the pipe body 1 can better fit the ground, thereby improving the stability of the pipe body 1. Since the diameters of both ends of the connecting piece 2 are larger than the diameter of the pipe body 1, it makes it more efficient and convenient for people to assemble the connecting piece 2 and the pipe body 1, saving installation time. Both ends of the connecting piece 2 are provided with annular grooves 10, and a tightening belt 3 for tightening the connecting piece 2 is rotatably connected in the annular grooves 10. By setting the annular grooves 10, the annular grooves 10 can play a role in limiting and guiding the rotation of the tightening belt 3, preventing the tightening belt 3 from detaching from the connecting piece 2, and at the same time improving the rotation efficiency of the tightening belt 3, facilitating people to assemble the connecting piece 2 and the pipe body 1. By setting the tightening belt 3 for tightening the connecting piece 2, when people insert the pipe body 1 into the connecting piece 2, the tightening belt 3 can be used to tighten both ends of the connecting piece 2, thereby improving the connection strength between the connecting piece 2 and the pipe body 1, preventing the two from detaching, and also avoiding the occurrence of pipeline leakage. At the same time, a sealing tape is provided between the pipe body 1 and the connecting piece 2, and the sealing tape can further prevent water in the pipeline from leaking, ensuring the sealing performance of the drainage pipe. Further, anti-corrosion coatings are applied on the inner walls of the pipe body 1 and the connecting piece 2, and the anti-corrosion coatings are made of epoxy resin material. By setting the anti-corrosion coatings, the inner walls of the pipe body 1 and the connecting piece 2 can be prevented from being corroded by sewage, and epoxy resin has strong chemical corrosion resistance, which can effectively prevent chemical substances such as acids, alkalis, and salts from eroding the pipe body 1 and the connecting piece 2, protecting the pipe body 1 and the connecting piece 2 from chemical corrosion and extending the service life of the pipe body 1 and the connecting piece 2.

[0022] Specifically, as Figure 1 and Figure 3As shown, a limiting ring 4 is provided at one end of the tightening belt 3, and a plurality of grooves 5 connecting the two sides of the tightening belt 3 are arranged in an array on the tightening belt 3. A protrusion 6 is formed between adjacent grooves 5, and the protrusion 6 can be embedded in the groove 5 and pressed against the inner wall of the groove 5. By providing the limiting ring 4 and the groove 5, when people use the tightening belt 3 to tighten the connector 2, they can pass the end of the tightening belt 3 away from the limiting ring 4 through the limiting ring 4, pull the tightening belt 3 and make the limiting ring 4 embedded in the appropriate groove 5, so that the tightening belt 3 can tighten the connector 2. The groove 5 can limit the limiting ring 4, preventing the limiting ring 4 from separating from the groove 5, thereby improving the connection strength between the tightening belt 3 and the limiting ring 4. By setting the protrusion 6 and the protrusion 6 can be embedded in the groove 5, after people have fixed the limiting ring 4, they can continue to embed the protrusion 6 on the movable end of the tightening belt 3 into the groove 5 on the tightening belt 3, thereby fixing the movable end of the tightening belt 3, improving the tightening effect and stability of the tightening belt 3, and making the connection strength between the connecting piece 2 and the tube body 1 higher.

[0023] Further, such as Figure 2 and Figure 4 As shown, the groove 5 is provided with a rounded corner at the notch and the diameter of the groove 5 is smaller than the diameter of the bottom of the groove 5. By setting the rounded corner, it is more convenient for people to embed the protrusion 6 on the movable end of the tightening belt 3 into the groove 5, reducing the wear between the groove 5 and the protrusion 6. Since the diameter of the notch of the groove 5 is larger than the diameter of the bottom of the groove, the protrusion 6 is not easy to fall out of the groove 5 when embedded in the groove 5, thereby improving the stability between the protrusion 6 and the groove 5, thereby further improving the connection strength between the connector 2 and the tube body 1.

[0024] like Figure 4 As shown, a through hole 7 is opened at one end of the tightening band 3, and the limiting ring 4 is rotatably connected in the through hole 7. Specifically, the limiting ring 4 includes an arc portion 8 and a straight portion 9. The arc portion 8 and the straight portion 9 are integrally formed. The integral forming can improve the connection strength between the arc portion 8 and the straight portion 9, making the limiting ring 4 more stable when limiting. The straight portion 9 is rotatably connected in the through hole 7 and the length of the straight portion 9 is equal to the length of the through hole 7. By setting the straight portion 9 and the through hole 7, the through hole 7 can guide the rotation of the limiting ring 4, which facilitates the rotation of the limiting ring 4. At the same time, the through hole 7 can also prevent the limiting ring 4 from separating from the tightening band 3, thereby improving the connection strength between the limiting ring 4 and the tightening band 3. Since the length of the straight portion 9 is equal to the length of the through hole 7, the limiting ring 4 will not rotate on the tightening band 3, thereby improving the stability of the limiting ring 4, making it more stable when people use the limiting ring 4 to fix the tightening band 3, and the fixing effect is better.

All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
