[0051] The water jacket 53 is fixedly connected to the bottom end of the connecting pipe 20, and a first anti-rotation portion 531 is provided on the inner wall of the water jacket 53, and the first anti-rotation portion 531 cooperates with the second anti-rotation portion 521 to prevent the water outlet pipe 30 from rotating circumferentially. The water jacket 53 and the connecting pipe 20 can be fixed in an integral molding or secondary injection molding manner, but are not limited thereto.

[0052] The water-passing sleeve 53 includes a first water-passing pipe 532 extending longitudinally and a second water-passing pipe 533 extending transversely. The bottom end of the connecting pipe 20 is fixedly connected to the first water-passing pipe 532. The limiting ring body 52 is located in the second water-passing pipe 533. The first stop portion 531 is a transversely extending groove and is arranged on the inner wall of the second water-passing pipe 533.

At this time, the first limiting step 511 is pressed against the outer end face of the limiting ring body 52.

[0061] Please refer to Figures 7 to 9 , which is a second embodiment of the water outlet pipe assembly of the wall-mounted shower faucet.

A flange 441 is also provided at the top end of the inner connecting member 44, and the flange 441 is pressed against the top end surface of the outer connecting member 43.

[0066] When the water outlet joint 10 needs to be connected to the connecting pipe 20, it is only necessary to first pass the bottom end of the connecting pipe 20 through the external connecting piece 43 until the seventh limiting step 23 abuts against the fifth limiting step 432, at which time the fourth limiting step 431 and the sixth limiting step 22 are flush; then, place the gasket 45 on the fourth limiting step 431 and the sixth limiting step 22; then, screw the internal connecting piece 44 and the external connecting piece 43 together until the bottom end of the internal connecting piece 44 is pressed against the top end surface of the gasket 45, at which time the first connecting component 40 and the connecting pipe 20 form a whole; finally, screw the internal connecting piece 44 and the water outlet interface 11 together until the bottom end of the water outlet interface 11 is pressed against the top end surface of the gasket 45, and the connection between the connecting pipe 20 and the water outlet joint 10 is completed.

[0067] The wall-mounted shower faucet is applied with the water outlet pipe assembly of the wall-mounted shower faucet. For the wall-mounted shower faucet, the shape and size of the water outlet joint 10 are different, but the water outlet interface 11 thereof adopts a threaded opening of a uniform size, so the water outlet pipe assembly is suitable for the installation of all wall-mounted shower faucets, and has strong universality.

[0068] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
