[0037] Example 2

[0038] This utility model provides, for example Figure 3 The novel water supply pipe shown includes a metal pipe body 1, a flange plate 2, a plastic inner tube 3, and a reinforcing component 4. The flange plate 2 is fixedly connected to the end of the metal pipe body 1 and is used for the fixed connection of adjacent metal pipe bodies 1. The metal pipe body 1 is made of iron. The plastic inner tube 3 is set inside the metal pipe body 1 and is made of plastic. The combination of the metal pipe body 1 and the plastic inner tube 3 can improve the overall performance of the water supply pipe. Under the action of the flange plate 2, it is convenient to connect and install adjacent water supply pipes. The reinforcing component 4 is set between the plastic inner tube 3 and the metal pipe body 1. The reinforcing component 4 is used to limit the plastic inner tube 3 inside the metal pipe body 1 and to provide pressure protection for the plastic inner tube 3 and the metal pipe body 1, thereby further improving the overall performance of the water supply pipe.

[0039] Furthermore, it also includes an annular groove and a raised edge ring 31. The annular groove is opened on one side of the flange plate 2, and the raised edge ring 31 is connected to the end of the plastic inner tube 3. The raised edge ring 31 is fitted inside the annular groove. Under the action of the raised edge ring 31, the plastic inner tube 3 can be prevented from sliding and separating from the metal tube 1 along the axis. It also includes a sealing ring 32 and an annular groove 33. The sealing ring 32 is fixedly connected to one side of one of the raised edge rings 31, and the annular groove 33 is opened on one side of the other raised edge ring 31. The inner cavity of the annular groove 33 matches the sealing ring 32. Thus, when adjacent water supply pipes are connected, the sealing ring 32 at one end of the plastic inner tube 3 connects with the annular groove 33 at one end of the adjacent plastic inner tube 3, which can improve the sealing performance of the connection between adjacent plastic inner tubes 3. Furthermore, the plastic inner tube 3, the raised edge ring 31, and the sealing ring 32 are integrally injection molded.

Figure 3 The reinforcing rod 44 is U-shaped, and the protrusion 45 is fixedly connected to the inside of the annular groove. A positioning hole is provided on one side of the protrusion 45. The end of the outer wall of the reinforcing rod 44 is slidably sleeved with the inner cavity of the positioning hole. Thus, during the injection molding production of the plastic inner tube 3, the end of the reinforcing rod 44 is inserted into the protrusion 45, and then the plastic inner tube 3 is injected. This allows the plastic inner tube 3 to wrap around and connect with the reinforcing rod 44. The connection between the reinforcing rod 44 and the protrusion 45 can prevent the plastic inner tube 3 from rotating relative to the metal tube 1, thereby ensuring the stability of the connection between the plastic inner tube 3 and the metal tube 1.
