Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0021] See Figures 1 to 3 As shown, a new type of water pump leather bowl structure includes a support plate 1, five bases 2 integrally formed on the support plate, the top surface of the base is integrally formed with a truncated cone-shaped connecting part 3, the top of the truncated cone-shaped connecting part is integrally formed with a spherical clamping part 4 and a truncated cone-shaped connecting head 5 integrally formed at the top of the spherical clamping part; and a transition annular groove 6 with a C-shaped cross-section is provided between the truncated cone-shaped connecting part and the base; through the above structure, a platform can be formed by the support plate, and cooperated with the base and the truncated cone-shaped connecting head, which is conducive to improving the convenience and effectiveness of assembly; in this embodiment, an annular groove is provided at the connection between the spherical clamping part and the truncated cone-shaped connecting part.

[0022] Five C-shaped relief grooves 7 are evenly spaced along the edge of the support plate, located in the gaps between adjacent bases. This facilitates assembly and use. A cavity 8 is formed on the bottom surface of the base, with a raised ring 9 integrally formed on the top of the inner wall. The position of the raised ring aligns with the position of the transition ring groove. This alignment of the raised ring and the transition ring groove enhances the strength of the joint, improving stability and effectiveness, as well as fatigue resistance and stability.

[0023] Furthermore, in actual use, the top edge of the support plate is integrally formed with an annular reinforcement flange 10. The height of the annular reinforcement flange is 1-3 cm. This structure can improve the strength of the overall structure, ensure stability and effectiveness in use, and is not easily damaged.

[0024] Moreover, in actual application, an arc-shaped groove 11 is provided on the symmetrical inner wall of the C-shaped avoidance groove. In addition, the top diameter of the truncated cone-shaped connecting part is smaller than the bottom diameter, and the diameter of the spherical clamping part is smaller than the top diameter of the truncated cone-shaped connecting part. The support plate, base, truncated cone-shaped connecting part, spherical clamping part and truncated cone-shaped connecting head are all silicone structures. At the same time, in this embodiment, a circular concave hole 12 is provided at the top center of the truncated cone-shaped connecting head. The depth of the circular concave hole can be set as needed, and it can be squeezed during assembly to facilitate the assembly and use of the truncated cone-shaped connecting head.
