In the description of the present invention, unless otherwise specified, "plurality" means two or more.

In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it can be mechanically connected, or electrically connected; it can also be directly connected, or indirectly connected through an intermediary, and it can be the internal communication of two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

An inlaid pipe sealing device of this embodiment, as shown in Figures 1 to 8, includes an injection molded part 1 and an inlaid pipe part 2 that can be embedded in the injection molded part 1, and a sealing ring groove 3 is provided on the outer surface of the inlaid pipe part 2 and two anti-slip parts 4, the sealing ring groove 3 is arranged along the circumferential direction of the outer surface of the inlaid pipe fitting 2, the sealing ring groove 3 is embedded with a sealing ring 5, each anti-slip part 4 adopts a concave part, and the anti-slip parts 4 can be distributed in the sealing The left and right ends of the ring groove 3 can also be distributed at any end of the sealing ring groove 3. Of course, the anti-slip part 4 can also be designed with other structures such as convex parts. 1 After molding, prevent the inlaid pipe fitting 2 from moving left and right, that is, the inlaid pipe fitting 2 will not be easily pulled out from the injection molded part 1. Of course, the more the number of anti-slip parts 4, the stronger the inlaid pipe fitting 2 will be.

When the anti-slip part 4 is designed as a convex part, the anti-slip part 4 can protrude in the shape of strips along the circumferential direction of the outer surface of the inlaid pipe fitting 2, or in the form of spaced raised columns, which can be used to fix the formed inlaid pipe fitting 2 during injection molding. Part 1 is not easy to pull out or move.

In addition, the inner wall of the inlaid pipe fitting 2 can adopt an internal thread design, which can be defined according to the injection molding product.

The present invention also includes a decorative panel 6 connected to one end of the inlaid pipe fitting 2. The decorative panel 6 can be integrally processed with the inlaid pipe fitting 2, or can be installed separately from the inlaid pipe fitting 2. When the decorative panel 6 is separated from the inlaid pipe fitting 2, the The decorative panel 6 is directly injection molded together with the injection molded part 1 , or the decorative panel 6 is pasted on the injection molded part 1 after the injection molded part 1 is injection molded.

Two inlaid pipes 2 can also be embedded in the injection molded part 1 of the present invention, and the injection molded part 1 and each inlaid pipe 2 have corresponding through holes 7 communicating with each other, allowing media to circulate, such as liquid or gas.

When the present invention is applied to the faucet plastic pipe 8, the faucet plastic pipe 8 includes a nozzle 10, a valve core seat 11, a hot and cold water pipe 12 and a base 13 which are integrally injection molded from top to bottom, and the nozzle 10 is used to connect the faucet outlet pipe , the spool seat 11 is used to fix the spool, the base 13 is provided with two inlaid pipe fittings 2, each inlaid pipe fitting 2 communicates with the hot and cold water pipes 12 respectively, and each inlaid pipe fitting 2 is provided with a sealing ring 5 and set On the non-slip parts 4 on both sides of the sealing ring, due to the elastic effect of the sealing ring, when the material is injected at high pressure, the injection molded part of the base wraps the inlaid pipe, and under the injection pressure, the sealing ring is squeezed to form two materials The first sealing of the bonding position. Furthermore, because the material needs to be melted at high temperature before injection to reach the injectable state, in the mold cavity, after the product is formed, it is a physical and natural phenomenon due to heat and cold contraction. The material of the wrapped base injection molding part shrinks again. At this time, the sealing ring on the inlaid pipe part 2 is squeezed again, and the sealing performance of the joint position of the two materials is also improved again. After the product is completed, in actual use, due to the sealing What the ring 5 adopts is an expandable environmentally friendly elastic sealing ring. If it is affected by liquid, gas and other media, due to the expandability of the sealing ring 5, the sealing performance is guaranteed again.
