[0028] By setting up a main structure including a pipe fitting 1 and an interface 2, a threaded section 3 is set in the interface 2, and a surrounding edge 10 with screw holes 11 is set outside the interface 2, and a sealing ring 4 is set in the interface 2. The double connection of threads and screws can greatly enhance the connection strength between the water pump interface 2 and the external pipeline, thereby avoiding the connection from being easily loosened during long-term use and improving the sealing ability of the water pump interface 2.

[0029] See also Figure 2-3 :

[0030] and elastic elements;

[0031] The elastic element includes a steel ring 5 and a compression spring 9. The steel ring 5 is bonded to the bottom of the sealing ring 4, and the compression spring 9 is arranged between the steel ring 5 and the inner bottom of the interface 2. A slide bar 6 is welded to the bottom of the steel ring 5, and multiple groups of slide bars 6 are arranged around the bottom of the steel ring 5 at equal intervals. A limit block 8 is welded to the lower end of the slide bar 6, and a slot 7 is opened at the inner bottom of the interface 2. The slide bar 6 is slidably inserted into the top of the slot 7, and the limit block 8 is located inside the slot 7. The compression spring 9 is slidably sleeved on the slide bar 6, and the upper end of the compression spring 9 abuts against the bottom of the steel ring 5, and the lower end of the compression spring 9 abuts against the inner bottom of the groove 12.

[0032] By arranging an elastic element including a steel ring 5 and a compression spring 9 in the interface 2, a sliding rod 6 with a limiting block 8 is arranged at the bottom of the steel ring 5, the sliding rod 6 is slidably inserted into the slot 7 at the bottom of the interface 2, and the compression spring 9 is sleeved on the sliding rod 6. Through the design of the elastic element, on the one hand, the connection strength between the sealing ring 4 and the external pipe interface 2 can be increased, thereby greatly improving the sealing of the water pump interface 2; on the other hand, the elastic element can cooperate with the threaded section 3 and the external pipe interface 2 for connection, increase the connection strength, avoid the phenomenon of thread slippage, and further avoid the phenomenon of looseness at the water pump interface 2.

[0033] Among them, the steel ring 5 is set to stainless steel, which can have the following advantages:

[0034] Corrosion resistance: Stainless steel contains chromium, which makes it non-corrosive in dry air and even resists rust in humid environments.

[0035] Heat resistance: Certain stainless steel varieties can maintain their strength and stability in extremely high-temperature environments, which makes them suitable for high-temperature processes and equipment.

[0036] Aesthetics: Stainless steel has a modern appearance, smooth surface, easy to clean and maintain, and is suitable for a variety of decorative and architectural uses.

[0037] Plasticity: Stainless steel can be made into different shapes and sizes through various processing methods to meet different design and application requirements.

[0038] Environmental protection: Stainless steel can be recycled and reused, reducing the impact of waste on the environment

[0039] Among them, the sealing ring 4 is set to be made of polyurethane rubber material, which has excellent wear resistance, high strength and good elasticity in the hardness range of Shore A60 to Shore A70, good buffering and shock absorption, the higher the vibration frequency, the greater the energy absorption, good oil resistance and chemical resistance, low affinity with non-polar mineral oil, almost no corrosion in fuel oil and machine oil, and a high friction coefficient.

[0040] See also Figure 2 :

[0041] A groove 12 is provided at the inner bottom of the interface 2 . The groove 12 is arranged in an annular shape and is used for retracting the compression spring 9 .

[0042] By setting a groove 12 at the bottom of the interface 2, the groove 12 is used for the retraction of the compression spring 9. When the water pump interface 2 and the external pipeline are connected, the sealing ring 4 moves down until it contacts the bottom of the interface 2. At this time, the compression spring 9 shrinks inside the groove 12, which can cause a gap at the bottom of the steel ring 5 to reduce the sealing performance.

[0043] The sealing ring 4 and the inner wall of the interface 2 are arranged in a sliding sealing manner.
