The reinforcing ring 3 is fixed at the port of the PE water supply pipe 1, and the sealing ring 2 is fixed at the leftmost side of the reinforcing ring 3.

[0029] The clamping groove 4 is opened on the reinforcing ring 3, and the clamp 8 is arranged inside the clamping groove 4.

[0030] Both of the two fasteners 9 are welded on the clamp 8, and threaded posts 7 are arranged on the inner surfaces of the two fasteners 9.

[0031] One end of the threaded post 7 is threadedly connected with a second locking nut 6, and the surface of the second locking nut 6 is in contact with the surface of the corresponding fastener 9.

[0032] The other end of the threaded post 7 is threadedly connected with a first locking nut 5, and the surface of the first locking nut 5 is in contact with the surface of the corresponding fastener 9.

[0033] The outermost layer of the PE water supply pipe 1 is the PE pipe outer layer 101. The PE pipe outer layer 101 is polyethylene coated with acid and alkali resistant paint. The acid and alkali resistant paint is corrosion resistant, can resist the corrosion of chemical substances such as acids, alkalis, and salt spray, can improve the corrosion resistance of the PE pipe.

[0035] Working principle:

[0036] When installing the PE water supply pipe;

[0037] First, drive the PE water supply pipe 1 to move to the water outlet end of the device by an external force, and make the left pipe orifice in contact with the water outlet end. At this moment, the sealing ring 2 is in contact with the water outlet device.

[0038] Secondly, drive the first locking nut 5 to move by an external tool. The movement of the first locking nut 5 drives the left fastener 9 to move. The movement of the left fastener 9 drives the clamp 8 to move and contract, thereby fastening the position relationship of the reinforcing ring 3, the PE water supply pipe 1 and the water outlet pipe.

[0039] By setting the sealing ring 2 and the reinforcing ring 3 in the reinforcing component, and fastening the reinforcing ring 3 at the position where the PE water supply pipe 1 and the water outlet end are located through the clamp 8, the fatigue strength of the pipe at the PE water supply pipe and the water outlet pipe is strengthened, and the damage at the pipe interface caused by the sudden change of water pressure at the interface for a long time is avoided, that is, the service life of the PE pipe is extended.

[0040] By setting the first lock nut 5 and the second lock nut 6, when the clamp 8 becomes loose, an external tool can be used to drive the first lock nut 5 and the second lock nut 6 to move, so as to re-tighten the two fasteners 9, thereby driving the clamp 8 to re-fasten the pipeline to the water outlet pipeline.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
