[0031] See also Figure 1-3 A water supply and drainage pipe connection structure includes a connecting pipe 1, with a pipe body 2 provided at both ends of the connecting pipe 1. The pipe body 2 and the connecting pipe 1 are provided with a positioning component for pre-connecting the pipe body 2 to the connecting pipe 1 and a fixing component for fixing. The positioning component includes a slot 10 and a plug plate 11;

[0032] The fixing assembly includes two annular arrays of fixing blocks 3 fixedly connected to the side walls of the pipe body 2. The fixing block 3 is hingedly connected to a swing plate 4 on the side wall close to the connecting pipe 1. The swing plate 4 is fixedly connected to a tension spring 5 for providing tension at one end away from the fixed block 3. The tension spring 5 can be swung by the hinged swing plate 4 to adjust the direction of the tension spring 5. A U-shaped frame 6 is installed on the end of the tension spring 5 away from the swing plate 4. The inner walls of the two ends of the U-shaped frame 6 away from the tension spring 5 are fixedly connected to the same clamping rod 7 for connecting to the connecting pipe 1. The side walls at both ends of the connecting pipe 1 are fixedly connected to two annular arrays of connecting blocks 8. The side walls on the opposite side of the two groups of connecting blocks 8 are provided with a clamping groove 9. By pulling the tension spring 5 to clamp the clamping rod 7 into the clamping groove 9, the tension spring 5 rebounds to fix the pipe body 2 to one end of the connecting pipe 1.

[0033] When in use, the pipe body 2 and the connecting pipe 1 are pre-connected through the positioning assembly, and then the U-shaped frame 6 is pulled to stretch the tension spring 5 and put the U-shaped frame 6 on the connecting block 8, and then the U-shaped frame 6 is released to allow the tension spring 5 to rebound and the clamping rod 7 to be clamped into the clamping groove 9, thereby fixing the pipe body 2 on the connecting pipe 1 and facilitating disassembly, thereby avoiding the problem of not being able to assemble and disassemble quickly, which reduces work efficiency.

[0034] Reference Figure 2 There are multiple slots 10 respectively opened at both ends of the connecting pipe 1 and distributed in a circular array, and there are multiple plug-in plates 11 respectively fixedly connected to one end of the pipe body 2 close to the connecting pipe 1 and distributed in a circular array. The plug-in plates 11 are respectively inserted into the slots 10. By inserting the plug-in plates 11 into the slots 10, the pipe body 2 and the connecting pipe 1 can be quickly positioned and connected.

[0035] Reference Figure 1 One end of the pipe body 2 close to the connecting pipe 1 is fixedly connected with a rubber pad 12, and the rubber pad 12 can improve the sealing performance of the connection between the pipe body 2 and the connecting pipe 1.

[0036] Reference Figure 1 The side walls on both sides of the U-shaped frame 6 are fixedly connected with a pull rod 13, which facilitates pulling the U-shaped frame 6 to stretch the tension spring 5.

[0037] Reference Figure 1 and Figure 3 , the side walls at both ends of the connecting pipe 1 are fixedly connected to two annular arrays of return frames 14, a push-pull plate 15 is provided in the return frame 14, and a push rod 16 is provided on the side of the return frame 14 away from the connecting pipe 1, one end of the push rod 16 passes through the return frame 14 and is fixedly connected to the push-pull plate 15, and the end of the push-pull plate 15 away from the push rod 16 is fixedly connected with an insertion rod 17, and the end of the insertion rod 17 away from the push-pull plate 15 passes through the return frame 14 and the connecting pipe 1 and is plugged into the insertion plate 11. After the insertion plate 11 is inserted into the slot 10, the push rod 16 is pushed to make the push-pull plate 15 plug the insertion rod 17 into the insertion plate 11, so as to prevent the pipeline body 2 from being subjected to tension during use and forming a gap with the connecting pipe 1.

[0038] Reference Figure 3 The push rod 16 is sleeved with a spring 18, and both ends of the spring 18 are fixedly connected to the push-pull plate 15 and the return frame 14. The spring 18 can push the push-pull plate 15 against one side of the return frame 14 to prevent the insertion rod 17 from moving.

[0039] Reference Figure 2A protective assembly is provided between the tension spring 5 and the U-shaped frame 6. The protective assembly includes a connecting rod 19 provided between the tension spring 5 and the U-shaped frame 6. Both ends of the connecting rod 19 are fixedly connected to the U-shaped frame 6 and the tension spring 5 respectively. A protective tube 20 is provided on the tension spring 5. The connecting rod 19 is slidably arranged in the protective tube 20. The end of the protective tube 20 away from the U-shaped frame 6 is fixedly connected to the swing plate 4. The protective tube 20 can improve the stability of the tension spring 5 and protect the tension spring 5 at the same time.

[0040] Reference Figure 2 The length of the insert plate 11 is smaller than the depth of the slot 10. After the clamping rod 7 is engaged with the clamping slot 9, the tension spring 5 moves the pipe body 2 closer to the connecting pipe 1, which will squeeze the rubber pad 12, making the rubber pad 12 fit more closely with the connecting pipe 1 and improving the sealing performance.

[0041] The implementation principle of this application is: when in use, first pull the push rod 16 to make the spring 18 contract, move the insertion rod 17 out of the slot 10, and then insert the insertion plate 11 into the slot 10 to connect the pipe body 2 with the connecting pipe 1, and then release the push rod 16 to make the spring 18 rebound to plug the insertion rod 17 and the insertion plate 11 to prevent the pipe body 2 from falling off the connection with the connecting pipe 1 when receiving tension, and then pull the U-shaped frame 6 to stretch the tension spring 5 to put the U-shaped frame 6 on the connecting block 8, and then release the U-shaped frame 6 to make the tension spring 5 rebound to clamp the clamping rod 7 into the clamping slot 9, fixing the pipe body 2 on the connecting pipe 1, and facilitating disassembly at the same time, avoiding the problem of not being able to assemble and disassemble quickly, which reduces work efficiency.
