[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] This invention provides a vibration-fatigue resistant rubber seal for water tanks. The device includes a water tank body 1 and a sealing ring 6. The sealing ring 6 is installed on the surface of the water tank body 1 and is made of EPDM rubber. This material has a saturated molecular structure, exhibits strong resistance to ozone and ultraviolet aging, and is not prone to cracking even after long-term use, making it particularly suitable for high-frequency vibration environments. This invention primarily addresses the problem of long-term vibration causing the rubber seal to loosen, leading to water tank leaks and other related issues.

[0022] For the device provided by this utility model, please refer to Figure 1-4 The following is a detailed introduction.

[0023] A fixing ring 13 is installed in the inner hole of the sealing ring 6. The inner hole of the fixing ring 13 is integrally formed with a third threaded hole 14. A connecting cylinder 2 is installed inside the fixing ring 13, and the bottom of the connecting cylinder 2 extends below the sealing ring 6. The outer wall surface of the connecting cylinder 2 is provided with an external thread 5. The connecting cylinder 2 is fixed inside the fixing ring 13 by the threaded connection between the external thread 5 and the third threaded hole 14. The connecting cylinder 2 is inserted into the inside of the sealing ring 6 through the connection with the fixing ring 13. A pressure plate 3 is provided at the upper end of the connecting cylinder 2, and the pressure plate 3 is attached to the upper part of the sealing ring 6. A mating hole 4 is provided inside the connecting cylinder 2, and the mating hole 4 connects the upper and lower sides of the connecting cylinder 2.
