[0021] like Figure 1-Figure 3 As shown, a high-strength and pressure-resistant PVC pipe comprises: a first connection end 1, characterized in that the first connection end 1 comprises a first connector 10 and a ball chain 11, the ball chain 11 is fixedly installed at one end of the first connection head 10, a push wedge 12 is installed at the lower end of the ball chain 11, the push wedge 12 is slidably connected to the first connection head 10, a second connection end 3 is fixedly installed at one end of the first connection end 1, the second connection end 3 comprises a second connector 15 and a top block 14, the second connection head 15 is slidably connected to the first connection head 10, one end of the second connection head 15 is fixedly connected to the top block 14, the top block 14 is connected to the push wedge 12, and the first connection head 10 and the second connection head 15 are fixedly connected via a locking ring 2.
[0022] In this way, the first connector 10 is docked with the second connector 15, and the top block 14 on the second connector 15 pushes the wedge 12 forward, thereby pushing the wedge 12 to lift the ball chain 11, and buckle it on the slot of the second connector 15 to fix it, and then fix it with the locking ring 2 on the outside of the first connector 10 and the second connector 15, and install and connect the pipeline through the locking structure of the ball chain 11 and the slot, and then fix the interface with the locking ring 2. The installation is simple and quick, and the construction efficiency is improved.
[0023] As an optional embodiment, the first connection end 1 and the second connection end 3 are fixedly connected with a PVC pipe 4 at both ends.
