[0032] The following will further elaborate on this application in conjunction with the attached Figures 1-3 drawings.

[0033] Please refer to Figures 1-3 , a PE water supply pipe connector assembly that can be quickly positioned and installed, including a pipe body 1 and a connecting sleeve 2 for connecting the pipe body 1. A connector 11 is fixedly connected to the end of the pipe body 1. Connecting holes 21 adapted to the connector 11 are provided at both ends of the connecting sleeve 2. By providing the connecting sleeve 2, when connecting PE water supply pipes, the connectors 11 of the two pipe bodies 1 can be respectively inserted into the two connecting holes 21 of the connecting sleeve 2.

[0034] Referring to Figure 1 , a plurality of positioning blocks 27 are provided on the inner circumference of the connecting hole 21, and a plurality of positioning grooves 13 adapted to the positioning blocks 27 are provided on the outer circumference of the connector 11. By providing the positioning blocks 27 and the positioning grooves 13, when inserting the connector 11 into the connecting hole 21, the positioning blocks 27 can be aligned with the positioning grooves 13 and slide in, which can play a guiding and positioning role for the connector 11 and facilitate the installation of the connector 11.

[0035] A contact ring 24 is provided inside the connecting sleeve 2 between the two connecting holes 21. A sealing ring 25 is in contact between the connector 11 and the contact ring 24. Through the arrangement of the contact ring 24 and the sealing ring 25, when the connector 11 is inserted into the connecting hole 21, the end of the connector 11 abuts against the sealing ring 25 of the contact ring 24, and a sealing effect can be achieved.

[0036] Referring to Figure 2 and Figure 3, on both sides of the connecting sleeve 2 close to the two connecting holes 21, there are clamping components 22. The clamping component 22 includes a spring 221, a clamping block 222, a connecting rod 223 and a collar 224. On the inner circumference of the connecting hole 21, there are a plurality of annularly distributed receiving grooves 23. The spring 221 is embedded in the receiving groove 23. The clamping block 222 abuts against one end of the spring 221. The clamping block 222 is provided with an inclined angle towards the opening direction of the connecting hole 21. On the outer circumference of the joint 11, there are a plurality of annularly distributed clamping grooves 12. By setting the clamping component 22, during the process of inserting the joint 11 into the connecting hole 21, the clamping block 222 will be forced to contract into the receiving groove 23 and compress the spring 221. When the clamping groove 12 is aligned with the clamping block 222, the spring 221 will release its elastic force and push the clamping block 222 into the clamping groove 12 to clamp and fix the joint 11, thus completing the quick positioning and installation of the PE water supply pipe. No tools are required, the operation is convenient, and the installation efficiency is improved.

[0037] The connecting rod 223 is fixedly connected to one end of the clamping block 222 close to the spring 221. The collar 224 is slidably sleeved on the surface of the connecting sleeve 2. On the inner circumference of the collar 224, there are a plurality of grooves 225. On the inner wall of the groove 225, there is a guiding groove 226. One end of the connecting rod 223 far from the clamping block 222 slides through to the inside of the groove 225 and is fixedly connected with a guiding block 227. The guiding block 227 slides in the guiding groove 226. When it is necessary to disassemble the PE water supply pipe, only need to slide the two collars 224 relative to each other, so that the collar 224 drives the guiding block 227 to slide in the guiding groove 226, the guiding block 227 drives the connecting rod 223 to slide, and the connecting rod 223 drives the clamping block 222 to move out of the clamping groove 12, then the joint 11 can be pulled out to realize the quick disassembly of the PE water supply pipe.

[0038] Refer to Figure 3 , on the inner wall of the receiving groove 23, there is a limiting groove. On both sides of the clamping block 222, there are limiting blocks 228. The limiting blocks 228 slide in the limiting groove. By setting the limiting blocks 228, the clamping block 222 can be limited.

[0039] Refer to Figure 1 and Figure 2 , on the outer circumference of the connecting sleeve 2, there is an annular groove 26. The collar 224 is embedded in the annular groove 26. By setting the annular groove 26, it can be avoided that the collar 224 protrudes from the connecting sleeve 2, and the probability of the collar 224 being touched can be reduced. On the surface of the annular groove 26, there is a sliding groove. The inner wall of the collar 224 is fixedly connected with a sliding block 229. The sliding block 229 slides in the sliding groove. By setting the sliding block 229, the collar 224 can be guided.

[0040] The implementation principle of this application is as follows: When connecting PE water supply pipes, the joints 11 of the two pipe bodies 1 can be respectively inserted into the two connection holes 21 of the connection sleeve 2. During the process of inserting the joint 11 into the connection hole 21, the clamping block 222 will be forced to contract into the receiving groove 23, and the spring 221 will be compressed. When the clamping groove 12 is aligned with the clamping block 222, the spring 221 will release its elastic force, pushing the clamping block 222 into the clamping groove 12 to clamp and fix the joint 11, thus completing the rapid positioning and installation of the PE water supply pipe. No tools are required, the operation is convenient, and the installation efficiency is improved. When it is necessary to disassemble the PE water supply pipe, just slide the two collar rings 224 relative to each other, so that the collar rings 224 drive the guide block 227 to slide in the guide groove 226, the guide block 227 drives the connecting rod 223 to slide, and the connecting rod 223 drives the clamping block 222 to move out of the clamping groove 12, then the joint 11 can be pulled out to realize the rapid disassembly of the PE water supply pipe.
