[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0028] First embodiment:

[0029] A type of faucet pipe, such as Figures 1 to 5 As shown, the device includes a pipe body, which consists of an outer pipe 1 and an inner pipe 2 fixed inside the outer pipe 1. The outer pipe 1 is used to install the pipe body, and the inner pipe 2 is used to connect the valve core 7 and the inlet / outlet water pipes 6. In this embodiment, the inner pipe 2 and the outer pipe 1 are cold-forged and then welded together, which can accurately achieve the required dimensions, avoid various problems caused by deformation during injection molding, and reduce the complexity of the process.

[0030] The inner tube 2 protrudes from the top of the outer tube 1 by a section. A raised edge 14 is provided on the peripheral wall of the protruding part of the inner tube 2, which fits against the top edge of the outer tube 1. The engagement of the raised edge 14 facilitates positioning and determination of the welding position by the workers during welding operations, while also improving the stability of the connection.

[0031] The inner tube 2 has an inlet 3 and an outlet 4 at its bottom. Inlet pipe 5 and outlet pipe 6 are respectively installed at inlet 3 and outlet 4, and are fixed together by a snap-fit ​​fitting 8. A valve core 7 is also installed inside the inner tube 2. A first external thread 10 is provided on the circumferential wall of the portion of the inner tube 2 protruding from the outer tube 1. A pressure cap 9 is connected to the inner tube 2 via the first external thread 10. The pressure cap 9 is annular, with a protruding abutment surface 13 on its inner ring. The abutment surface 13 fits against the valve core 7, pressing it in place and thus installing the valve core 7. A second external thread 11 is provided on the circumferential wall of the pressure cap 9, which is connected to the faucet housing via the second external thread 11. A third external thread 12 is provided on the circumferential wall of the outer tube 1.

[0032] A ring-shaped mounting ring 17 protrudes from the peripheral wall of the valve core 7. The bottom of the mounting ring 17 fits against the top of the inner tube 2, and the top of the mounting ring 14 fits against the abutment surface 13. That is, when the gland 9 is installed on the first external thread 10, the gland 9 and the inner tube 2 form an annular groove, and the mounting ring 17 of the valve core 7 is engaged in the groove. Furthermore, a mounting block 23 protrudes from the bottom of the mounting ring 17, and a positioning groove 24 that mates with the mounting block 23 is opened on the top of the inner tube 2. When the valve core 7 is installed into the inner tube 2, the mounting block 23 and the positioning groove 24 are engaged to achieve the positioning of the valve core 7. Specifically, two mounting blocks 23 are symmetrically arranged at the bottom of the mounting ring 17, and two matching positioning grooves 24 are opened on the top of the inner tube 2.

[0033] Both the inlet pipe 5 and the outlet pipe 6 are equipped with connectors 16 at their top ends. The circular connectors 16 pass through the circular inlet 3 and outlet 4, allowing the inlet pipe 5 and outlet pipe 6 to be connected and rotated through the connectors 16. A channel for water passage runs through the middle of the connector 16. A retaining groove 18 is provided on the peripheral wall of the portion of the connector 16 outside the inlet 3 / outlet 4. A retaining element 8 is fixed to the bottom of the connecting part 15, and the retaining element 8 engages with the retaining groove 18 to limit the movement of the inlet pipe 5 and outlet pipe 6. Two notches 20 are provided on the retaining element 8, which respectively pass into the retaining grooves 18 of the two connectors 16. The retaining element 8 is fixed to the bottom of the connecting part 15 with screws 21, preventing the connector 16 from coming out and allowing it to rotate in place, thus preventing the inlet pipe 5 and outlet pipe 6 from becoming entangled.

[0034] The inner tube 2 has an integrally formed connecting part 15, and the bottom end of the valve core 7 is fitted with the connecting part 15. The inlet 3 and outlet 4 are opened on the connecting part 15, with the bottom ends of the inlet 3 and outlet 4 passing through the connecting part 15 and the top ends communicating with the inside of the inner tube 2 respectively. The inlet of the valve core 7 is located at the bottom and communicates with the inlet 3, and the outlet of the valve core 7 is located on the side wall and communicates with the inside of the inner tube 2. Water flows from the outlet of the valve core 7 into the inner tube 2 and then into the outlet 4.

[0035] The outer tube 1 is connected to the flange 22 via a third external thread 12 and a quick-release nut 19. The tube body is installed and fixed to the flange 22 using the quick-release nut 19 and flange 22, avoiding the problem of difficulty in tightening with a screwdriver, greatly improving the user experience. Specifically, during installation, the flange 22 is placed against the top of the countertop, and the quick-release nut 19 is screwed upwards and pressed against the bottom of the countertop, clamping the tube body to fix it to the countertop. The integrated third external thread 12 on the outer tube 1's sidewalls can connect to flanges 22 of different sizes, allowing for installation on countertops of different thicknesses.

[0036] In this embodiment, the pipe body is made of stainless steel, including an outer pipe 1 and an inner pipe 2. The cap 9, inlet pipe 5, and outlet pipe 6 are also made of stainless steel. Compared to copper components, this method is lower in cost, has higher structural strength, and reduces the risk of injury to the human body.

[0037] The installation process of this utility model is as follows:

[0038] Install the valve core 7 into the inner tube 2, and then tighten the cap 9 on the top of the inner tube 2 with a wrench to press the valve core 7 down; use the notch 20 of the snap-fit ​​8 to snap into the inlet pipe 5 and the outlet pipe 6 respectively, and then install the inlet pipe 5 and the outlet pipe 6 into the inlet 3 and the outlet 4 of the inner tube 2. Use the screw 21 to fix the snap-fit ​​8 to the bottom of the inner tube 2. After installation, install it into the corresponding basin hole, and then install the gasket and quick-release nut 19 respectively. Tighten the quick-release nut 19 to fix the pipe body on the countertop.

[0039] Second embodiment:

[0040] A type of faucet pipe, such as Figure 6 As shown, the difference between this embodiment and the first embodiment is that the tube body is directly formed by cold forging, and the inner tube and the outer tube are formed as one piece.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.

[0042] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
