At the upper end of the connecting clamp 9, a connecting rod 10 is rotatably installed. At the lower end of the connecting rod 10, a fixing block 11 is fixedly installed. At the lower end of the fixing block 11, a locking clamp 12 is rotatably installed. At the outer end of the connecting head 2, a fastening ring 5 is integrally and fixedly installed. At the outer end of the fastening ring 5, the locking cap 1 is threadedly connected. Inside the connecting head 2, a second sealing ring 8 is provided, making the connection between the pipe 13 and the locking cap 1 and the connecting head 2 more stable and reliable, and having a longer service life.
[0023] The inner end of the locking clamp 12 is closely attached to the pipe 13, and the pipe 13 passes through the inside of the locking cap 1 and the connecting head 2. The limiting rings 3 are symmetrically arranged outside the connecting clamp 9, and the connecting clamp 9 and the locking clamp 12 are arranged in parallel. At the inner end of the locking cap 1, a threaded groove 6 is provided, and the locking cap 1 is threadedly connected to the connecting head 2. At the inner end of the threaded groove 6, a first sealing ring 7 is provided, and the fastening ring 5 is threadedly connected inside the threaded groove 6.

[0024] Specific working principle:
[0025] As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, when using this PE pipe connection structure, remove the locking cap 1 from the connector 2. First, put the locking cap 1 on the joint of the PE pipe to be connected, then insert the joint of the PE pipe into the inside of the connector 2, and then thread-connect the locking cap 1 with the connector 2. When turning the locking cap 1, the fastening ring 5 on the connector 2 is thread-connected into the inside of the thread groove 6, and the fastening ring 5 also plays a certain role in squeezing and fastening the locking cap 1, so that the inner end of the locking cap 1 closely fits the outer end of the pipe 13. Then open the connecting clamp 9 and put it on the outer end of the clamping groove 4, and then fix it with bolts. Open the locking clamps 12 on both sides and put them on the outer end of the pipe 13, and then fix it with bolts. When the left pipe 13 wants to move to the left, the locking clamp 12 pulls the connecting clamp 9 and the locking clamp 12 on the other side through the fixing block 11 and the connecting rod 10, so that the position of the locking clamp 12 cannot move, playing a role in strengthening the pipe 13 and preventing the pipe 13 from shifting and loosening. The above completes a series of operations of this PE pipe connection structure. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
