[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The present embodiment is a special-shaped socket-and-spigot water pipe elbow.

[0025] like Figure 1-4 As shown, it includes a special-shaped socket elbow 1, an elliptical large tube 2 and an elliptical small tube 3. The special-shaped socket elbow 1 includes a water pipe elbow 4, an upper flat section 5, a lower flat section 6, a limiting ring 7, a first rubber ring 8 and a second rubber ring 9. The outer surface of one end of the elliptical small tube 3 is connected to the upper flat section 5, and one end of the elliptical large tube 2 is connected to the lower flat section 6.

[0026] The upper flat section 5 is connected to the outer surface of the upper end of the water pipe elbow 4, and the lower flat section 6 is connected to the outer surface of the lower end of the water pipe elbow 4; the cross-sectional shapes of the water pipe elbow 4, the upper flat section 5 and the lower flat section 6 are all elliptical; the inner diameter of the upper flat section 5 is larger than the inner diameter of the water pipe elbow 4, and the inner diameter of the lower flat section 6 is the same as the inner diameter of the water pipe elbow 4; the number of the second rubber rings 9 is two groups, and the two groups of second rubber rings 9 are fixedly installed on the inner wall of the upper flat section 5, the number of the first rubber rings 8 is three groups, and the three groups of lower flat sections 6 are fixedly installed on the outer wall of the middle and lower part of the lower flat section 6 at equal intervals, and the limit ring 7 is fixedly installed on the outer wall of the upper part of the lower flat section 6; the outer wall of one end of the elliptical small tube 3 is plugged into the inner wall of the upper flat section 5, and the outer wall of the lower flat section 6 is plugged into the upper part of the inner cavity of the elliptical large tube 2.

[0027] It should be noted that the utility model is a special-shaped socket elbow for water pipes. When connecting the elliptical small tube 3 with the special-shaped socket elbow 1, it is only necessary to insert one end of the elliptical small tube 3 into the interior of the upper flat section 5. The second rubber ring 9 is squeezed between the inner wall of the upper flat section 5 and the outer wall of the elliptical small tube 3, which plays a sealing role and improves the stability of the connection between the elliptical small tube 3 and the special-shaped socket elbow 1. The inner diameter of the upper flat section 5 is larger than the inner diameter of the water pipe elbow 4. Therefore, one end of the water pipe elbow 4 can limit the elliptical small tube 3; when the elliptical large tube 2 and the special-shaped socket elbow are connected, the second rubber ring 9 is squeezed between the inner wall of the upper flat section 5 and the outer wall of the elliptical small tube 3, which plays a sealing role and improves the stability of the connection between the elliptical small tube 3 and the special-shaped socket elbow 1. When connecting the heads 1, the lower flat section 6 of the lower part of the special-shaped socket elbow 1 is inserted into the interior of the elliptical large tube 2, and the first rubber ring 8 is squeezed between the outer wall of the lower flat section 6 and the inner wall of the elliptical large tube 2, and the first rubber ring 8 is squeezed between the outer wall of the lower flat section 6 and the inner wall of the elliptical large tube 2, which plays a sealing role and improves the stability of the connection between the elliptical large tube 2 and the special-shaped socket elbow 1. The limiting ring 7 is provided to play a limiting role. The first rubber ring 8 and the second rubber ring 9 are provided to improve the stability and sealing of the plug-in between the elliptical pipes.
