DETAILED DESCRIPTION

[0016] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0017] like Figure 1 As shown, a lightweight water pump return pipe includes an injection molded straight pipe 1 and a manifold 2. A detachably connected bracket 4 is provided on the straight pipe 1, and the bracket 4 has the effect of reducing the difficulty of matching with the straight pipe 1 and improving the installation and fixing stability of the straight pipe 1. A flange 3 for installation and fixing is provided on the manifold 2, so that the flange 3 can achieve the effect of improving the installation and fixing stability of the manifold 2.

[0018] It should be noted that a rotary sealing welding interface 6 is provided between the straight pipe 1 and the manifold 2. The rotary sealing welding interface 6 makes the straight pipe 1 and the manifold 2 perform relative circumferential rotational motion, so that the corresponding ends of the straight pipe 1 and the manifold 2 are heated due to friction, and then melt at the contacting parts to connect with each other and achieve effective sealing. At the same time, at least one extension pipe 21 is connected to the outer wall of the manifold 2. A rotary sealing welding interface 6 is formed between the extension pipe 21 and the manifold 2 to reduce the difficulty of matching and connecting the extension pipe 21 with the manifold 2, and further reduce the production and preparation cost of the lightweight water pump return pipe while maintaining the sealing performance.

[0019] like Figure 2 As shown, the rotary sealing welding interface 6 includes a sealing A end 61 and a sealing B end 62. The sealing A end 61 and the sealing B end 62 are respectively located between the extension tube 21 and the manifold 2 and between the straight tube 1 and the manifold 2, which are matched and sealed with each other. Therefore, a stable sealing connection structure will be formed between the extension tube 21 and the manifold 2 and between the straight tube 1 and the manifold 2. It should be mentioned that a toothed A surface 611 is provided on the sealing A end 61, and a toothed B surface 621 is provided on the sealing B end 62. Among them, the toothed A surface 611 and the toothed B surface 621 match each other and are used to generate melting phenomenon after rotating friction heat to achieve sealing welding.

[0020] like Figure 3 As shown, the bracket 4 includes two fixing seats 41 respectively located on both sides of the straight pipe 1. A connecting elastic band 42 is connected between the two fixing seats 41, and the fixing seat 41 is used for installation and fixing, and then when the connecting elastic band 42 contacts the outer peripheral side wall of the straight pipe 1, pressure is applied to the straight pipe 1, thereby achieving the purpose of improving the installation and fixing stability of the straight pipe 1. At the same time, an insert 5 is provided on the fixing seat 41 and the flange 3, and the fixing seat 41 is provided with a fixing socket 43 for adjusting the installation of the connecting elastic band 42. Therefore, for straight pipes 1 with different diameters, the length of the connecting elastic band 42 located between the two fixing seats 41 can be adjusted, thereby improving the adaptability of the bracket 4 and achieving the purpose of reducing the production cost of the bracket 4.

[0021] In summary, the present application provides a lightweight water pump return pipe, which realizes a stable sealing structure in the connection structure of the rotary sealing welding interface 6 by adopting an injection-molded straight pipe 1 and a manifold 2. The overall structure is simple and achieves the effects of lightweight, cost reduction and good sealing performance.
