[0007] Furthermore, a shock-absorbing strip is provided between two adjacent reinforcement strips, one side of the shock-absorbing strip is fixedly connected to the surface of the PVC pipe, and the other side of the shock-absorbing strip is in contact with the inner wall of the thermal insulation cotton.

[0008] Furthermore, the thermal insulation cotton is covered with a rubber sleeve.

[0009] Furthermore, a sealing ring is provided between the convex ring and the PVC tube.

[0010] Furthermore, a support is fixed on the connecting pipe, a limiting groove is provided on the support, two support members are slidably connected in the limiting groove, circular grooves are provided on opposite sides of the two limiting rings, the opposite ends of the two support members extend out of the support and are inserted into the corresponding circular grooves, and a compression spring is provided between the two support members.

[0011] Furthermore, the support member includes an insertion rod hinged at one end of the slider, the free end of the insertion rod can be inserted into the corresponding circular groove, the slider is slidably connected to the limiting groove, and the two sliders are connected via a compression spring.

[0012] The utility model has the following beneficial effects: by arranging reinforcement strips on the surface of the PVC pipe, the bearing strength of the PVC pipe is reinforced, and the arrangement of the thermal insulation cotton can keep the PVC pipe warm. By inserting the two ends of the connecting pipe into the two PVC pipes respectively and making the two nuts be threadedly connected with the corresponding PVC pipes, the two PVC pipes can be connected, thereby fixing the connection of the two PVC pipes, avoiding the problem that the water pipe is subjected to water pressure shock for a long time, causing the two PVC pipes to loosen and fall off.
