[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0021] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] Reference Figure 1-Figure 3 The embedded water outlet pipe provided by the utility model includes a U-shaped pipe 2 and a connecting ring 3. In actual use, the water inlet of the U-shaped pipe 2 is connected to the water outlet of the mixing valve 1, and the connecting ring 3 is clamped and arranged between the two. An annular sealing gasket 4 is arranged at one end of the connecting ring 3, and a sleeve 301 is connected to the other end of the connecting ring 3. A sealing ring 5 is arranged on the outer side wall of the sleeve 301. The sleeve 301 extends into the water inlet of the U-shaped pipe 2 and is sealed and connected with it through the sealing ring 5. Even if the U-shaped pipe 2 rotates, it will not cause sealing failure. Two sealing rings 5 ​​are arranged along the axial direction, and the sealing performance is better. When the U-shaped pipe 2 rotates, it provides better sealing.

[0024] In this embodiment, the water inlet of the U-shaped pipe 2 is provided with an external thread, the water outlet of the mixing valve 1 is provided with an internal thread, the connecting ring 3 is placed in the water outlet of the mixing valve 1, and is clamped between the two by the water inlet end of the U-shaped pipe 2, and the connecting ring 3 and the annular sealing gasket 4 are tightened by the threaded knob to achieve a sealing effect.

[0025] In order to better realize the utility model, further optimization is made in the above structure, and the sealing ring 5 is made of silicone. The annular sealing pad 4 is also made of silicone. Silicone has excellent reliability and compressibility. It is soft and elastic, and has excellent physical properties when used in the sealing field. The U-shaped pipe 2 and the connecting ring 3 are both made of copper. Copper pipe fittings will not be oxidized or corroded and can withstand years of use. Copper pipe fittings are highly reliable because they are not affected by factors such as low temperature, high temperature, pressure, and vibration during use. They can withstand pressure and weight and maintain their structural stability. In addition, copper pipe fittings have good sealing properties, which prevents water leakage and pipe rupture. A mounting seat 201 is provided on the U-shaped pipe 2, and the U-shaped pipe 2 is fixed in the wall by means of the mounting seat 201 to improve the reliability of pipeline operation.

[0026] During installation, first install the annular sealing gasket 4 and the sealing ring 5 on the connecting ring 3, then put the connecting ring 3 into the water outlet of the mixing valve 1, and clamp it between the two through the water inlet end of the U-shaped connecting pipe 2, tighten the connecting ring 3 and the annular sealing gasket 4 through the threaded knob, and at the same time, the sealing ring 5 is sealed and connected to the inner wall of the water inlet of the U-shaped connecting pipe 2, and then adjust the rotation angle of the U-shaped connecting pipe 2, finally determine the installation angle, and then fix the U-shaped connecting pipe 2 in the wall with screws through the mounting seat 201, and complete the pipeline pre-embedding.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
