[0002] Irrigation pipes are key components in agricultural irrigation systems used to transport water from water sources to farmland to meet the water needs of crop growth. Irrigation pipes can be divided into various types according to their materials and uses, such as PVC irrigation pipes, PE irrigation pipes, and metal pipes. Irrigation pipes are the core components of modern agricultural irrigation systems, and PVC and PE pipes have become the mainstream choices due to their corrosion resistance, light weight, and long service life.

[0003] However, in the existing technology, most of the existing irrigation pipes use fixed straight joints or rigid elbows. These pipes are basically connected by flanges or threads. When people need to adjust the irrigation direction, they first need to use tools to disassemble the pipes and then reinstall them in the opposite direction to complete the adjustment. In actual work, the operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0021] Example 1 like Figure 1-6As shown, this utility model provides a technical solution: a diverter for irrigation pipes, comprising: an irrigation pipe 11 and a water delivery pipe 12, with a connecting structure 2 between the irrigation pipe 11 and the water delivery pipe 12. The connecting structure 2 includes a first connecting pipe 21 and a second connecting pipe 22. An inner pipe 23 is fixedly installed on the top of the second connecting pipe 22. A bearing body 24 is rotatably installed on the inner side of the first connecting pipe 21. Two square grooves 25 are opened on the inner side of the bearing body 24. Two square blocks 26 are fixedly installed on the outer side of the inner pipe 23. An annular groove 27 is opened on the inner side of the first connecting pipe 21. An annular plate 28 is provided on the inner side of the annular groove 27. Four return springs 29 are fixedly installed on the top of the annular plate 28. A moving ring 210 is fixedly installed on the top of each of the four return springs 29. A limit post 211 is fixedly installed on the inner side of each of the four moving rings 210. The inner pipe 23 is located on the bearing body. The inner side of the body 24 and slides in contact with the bearing body 24. Two square blocks 26 are respectively set inside the two square sliding grooves 25 and slide in contact with the bearing body 24. The bottom of the annular sliding groove 27 is formed with an annular through groove 212. Four limiting posts 211 pass through the annular through groove 212 and slide in contact with the first connecting pipe 21. The four limiting posts 211 are fixedly installed on the top of the second connecting pipe 22. A fixing ring 213 is provided inside the annular sliding groove 27. The fixing ring 213 is fixedly installed on the top of the inner side of the annular sliding groove 27. The fixing ring 213 has several limiting grooves 214. The radius of the limiting posts 211 matches the radius of the several limiting grooves 214. The top of the second connecting pipe 22 is fixedly installed with a first sealing ring gasket 215. The bottom of the first connecting pipe 21 has a first sealing ring groove 216. The first sealing ring gasket 215 and the first sealing ring groove 216 are adaptively matched.

[0022] In this embodiment, the two square blocks 26 and two square grooves 25 work together to effectively limit the movement between the inner tube 23 and the bearing body 24. The two square blocks 26 are respectively located inside the two square grooves 25, and when the inner tube 23 rotates, it can drive the inner ring of the bearing body 24 to rotate. That is, when the second connecting tube 22 rotates, it will not affect the fixed state of the first connecting tube 21. The two square blocks 26 can slide inside the two square grooves 25, and there will be no jamming when adjusting the direction of the joint. The annular through groove 212 works with the four limiting posts 211, so that the four limiting posts 211 can pass through the annular through groove 212 and can move in a circle inside the annular through groove 212 without being obstructed. The fixed ring 213 has several limiting grooves 214, so that the four limiting posts 211 can be inserted into the limiting grooves 214 to limit the movement and prevent the joint from rotating due to water flow during use and affecting the irrigation direction.

[0023] Example 2 like Figure 1-6 As shown, a second sealing ring gasket 217 is fixedly installed at the bottom of the first connecting pipe 21, and a second sealing ring groove 218 is opened at the top of the second connecting pipe 22. The second sealing ring gasket 217 and the second sealing ring groove 218 are compatiblely matched. A first flange 13 is fixedly installed on the outer side of one end of the irrigation pipe 11 and the water supply pipe 12. A second flange 14 is fixedly installed on the outer side of one end of the first connecting pipe 21 and the second connecting pipe 22. The two first flanges 13 and the two second flanges 14 are fixedly connected by several fixing bolts 15.

[0024] In this embodiment, by adapting the first sealing ring gasket 215 and the first sealing ring groove 216, when the first connecting pipe 21 and the second connecting pipe 22 are connected, the first sealing ring gasket 215 will enter the interior of the first sealing ring groove 216 and deform to fill the first sealing ring groove 216, thus completing the initial sealing of the first connecting pipe 21 and the second connecting pipe 22. By adapting the second sealing ring gasket 217 and the second sealing ring groove 218, when the first connecting pipe 21 and the second connecting pipe 22 are connected, the second sealing ring gasket 217 will enter the interior of the second sealing ring groove 218 and deform to fill the second sealing ring groove 218, thus completing the further sealing of the first connecting pipe 21 and the second connecting pipe 22. This effectively ensures the sealing effect of the joint, avoids water leakage during use, and improves the performance of the joint.

[0025] Working principle: like Figure 1-6 As shown, during use, several fixing bolts 15 are used to fix the first flange 13 on the outside of the irrigation pipe 11 and the water delivery pipe 12 to the second flange 14 on the outside of the first connecting pipe 21 and the second connecting pipe 22, thereby completing the splicing operation of the water pipes. When it is necessary to adjust the irrigation direction of the water pipes, pulling the second connecting pipe 22 will move the four limiting posts 211 accordingly, thereby removing the four limiting posts 211 from the limiting groove 214 of the fixing ring 213, thus releasing the limiting effect between the first connecting pipe 21 and the second connecting pipe 22. At this time, the second connecting pipe 22 can be rotated to adjust the second connecting pipe 22. After adjusting the connection direction of the connecting pipe 22, loosen the second connecting pipe 22. Through the elastic action of the four return springs 29, the moving ring 210 and the limiting post 211 will move, so that the four limiting posts 211 are inserted into the limiting groove 214 of the fixed ring 213 to complete the limiting and fixing operation. At the same time, the first sealing ring gasket 215 and the second sealing ring gasket 217 will be inserted into the first sealing ring groove 216 and the second sealing ring groove 218 respectively to seal the connection. The direction of the water pipe connector can be adjusted without the use of tools, making the connector more convenient to use and effectively improving the practicality of the connector.
