[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] A water outlet pipe fixing structure of a water nozzle, such as Figure 1 As shown, it can be applied to zinc alloy basin faucets, and its structure includes a valve body 1, a valve core seat 2 and a valve core 3 in the valve body, a handle 4 on the top of the valve body for controlling the opening and closing of the valve core, a water outlet nozzle 11 extending outward from one side of the valve body, and a water outlet pipe 5 in the water outlet nozzle. One end of the water outlet pipe extends into the valve body 1 as a water inlet end 51, and the other end of the water outlet pipe serves as a water outlet end 52. Usually, a bubbler 6 is provided at the end of the water outlet nozzle 11 away from the valve body 1, and the water outlet end 52 of the water outlet pipe 5 is sealed and connected to the bubbler 6 to form water outlet.

[0023] The water inlet end 51 is as follows Figure 4 As shown, it is mainly composed of a water inlet vertical pipe 511 and a water inlet horizontal pipe 512. The water inlet vertical pipe 511 is a cylindrical pipe with a through top and a closed bottom, and the water inlet horizontal pipe 512 is a cylindrical pipe with two through ends.

[0024] The valve body 1 is provided with a mounting platform 12. Specifically, the mounting platform is arranged in the middle of the valve body 1, so the top of the valve body above the mounting platform 12 forms a mounting cavity 13 for installing the valve core seat 2 and the valve core 3. Usually, the valve core seat 2 is first installed into the mounting cavity 13 and positioned and installed on the mounting platform 12, and then the valve core 3 is installed on the valve core seat 2. Then, by tightening the nut 7 at the top of the mounting cavity 13, the valve core 3 and the valve core seat 2 can be firmly locked in the mounting cavity 13. Otherwise, the valve core 3 and the valve core seat 2 can be taken out of the mounting cavity 13 in sequence.

[0025] The positioning and installation structure between the valve core seat 2 and the installation platform 12 is that a positioning boss 21 and a positioning groove 121 are respectively provided between the valve core seat 2 and the installation platform 12. Of course, other positioning and installation structural modes can also be selected.

[0026] The valve core seat 2 is provided with Figure 3 The water inlet hole 23 and the water outlet hole 22 of the connecting valve core 3 are shown. The water outlet hole is arranged in the middle of the valve core seat 2 and is a cylindrical light hole structure. There are two water inlet holes 23, which are respectively located on both sides of the water outlet hole 22. Each water inlet hole 23 is a threaded hole. The two water inlet holes 23 are usually divided into a cold water hole and a hot water hole, which can be used for threaded connection of the cold water hose and the hot water hose respectively.

[0027] The water inlet end 51 of the water outlet pipe 5 is first detachably sealed and connected to the water outlet hole 22 of the valve core seat 2, and then the valve core seat 2 is positioned and installed on the installation platform 12 to form a clamping connection with the water inlet end 51.

[0028] Among them, the top end of the water inlet vertical pipe 511 is a detachable sealing plug-in connection formed by a sealing ring 8, such as an O-ring, which is fixed by the sleeve and contacts the water outlet hole 22, and the bottom end of the water inlet vertical pipe 512 is positioned and fitted in the positioning hole 122 on the installation platform 12, and positioning grooves 9 are respectively provided between the valve core seat 2 and the installation platform 12. When the valve core seat 2 and the installation platform 12 are positioned and fitted, the two positioning grooves 9 are just engaged with each other, so that the water inlet horizontal pipe 512 is also positioned and fitted.

[0029] Therefore, compared with the traditional plug-in connection structure, this clamping connection structure can firmly fix the water inlet end 51 between the valve core seat 2 and the installation platform 12, and prevent the water inlet end 51 from being loosened by positioning and fitting. Therefore, even if it is affected by the impact of water pressure changes in the outlet pipe 5, the water inlet end 51 will not accidentally fall off from the water outlet hole 22. The connection structure is more reliable and has stronger sealing, thereby effectively reducing the risk of water leakage and increasing the service life.

[0030] At the same time, the water inlet end 51 can be removed smoothly by simply taking out the valve core 3 and the valve core seat 2 from the installation cavity 13 at the top of the valve body 1, and then pushing the water inlet end outward to remove the water outlet pipe 5 from the water outlet nozzle 11. Therefore, the installation and disassembly are extremely convenient, which is conducive to the later disassembly, assembly, maintenance and replacement.

[0031] The installation platform 12 needs to be provided with an installation notch 123, the purpose of which is to allow both water inlet holes 23 to be exposed from the bottom through the installation notch 123, so as to facilitate the installation of the cold water hose and the hot water hose.

[0032] The water outlet pipe fixing structure of the utility model has a wide range of applications, is not limited by the size of accessories, and has the advantages of high versatility. In particular, the disassembly and assembly process is simple and reliable, which greatly improves the installation efficiency and effectively reduces the construction time and construction costs.

[0033] The above embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should also be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope of the claims appended hereto.
