[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] In the utility model, when the sealing ring body is installed in the equipment, the second sealing ring can more effectively fit with the contact surface of the equipment to reduce the gap, thereby preventing fluids or substances such as liquids, gases and dust from leaking or penetrating into the interior of the equipment from the gap between the two components, thereby improving the sealing performance of the sealing ring;

[0017] See also Figures 1 to 3 A high-performance waterproof sealing ring includes a sealing ring body 1, which includes a first sealing ring 2 and a second sealing ring 3 arranged on the top and bottom of the first sealing ring 2. A cavity 4 is opened inside the interlayer of the first sealing ring 2, and the cavity 4 is an annular structure. A plurality of springs 5 ​​distributed in a circular array are vertically arranged inside the cavity 4; convex rings 6 are arranged on both sides of the two second sealing rings 3 that are opposite to each other.

[0018] In this embodiment: two second sealing rings 3 are arranged at the top and bottom of the first sealing ring 2, and the outer diameter of the second sealing ring 3 is greater than the outer diameter of the first sealing ring 2. When the sealing ring body 1 is installed in the device, the second sealing ring 3 can fit the contact surface of the device more effectively to reduce the gap, thereby preventing fluids or substances such as liquids, gases and dust from leaking or penetrating into the interior of the device from the gap between the two components, thereby improving the sealing performance of the sealing ring;

[0019] Installing the spring 5 in the cavity 4 of the first sealing ring 2 can enhance the stability and pressure resistance of the sealing ring, and make the sealing ring body 1 have better pressure resistance and resilience, which can greatly extend the service life of the sealing ring;

[0020] The convex ring 6 on the second sealing ring 3 can make the sealing ring body 1 extend to both sides after being squeezed, which has a good sealing effect and makes the sealing ring body 1 fit tightly with the setting groove.

[0021] As a technical optimization solution of the utility model, flexible sleeves 7 fixedly connected to the inner wall of the cavity 4 are provided on both sides of the spring 5 .

[0023] As a technical optimization solution of the present invention, a support sleeve 8 with an annular structure is arranged inside the interlayer of the second sealing ring 3 .

[0024] In this embodiment, the support sleeve 8 increases the sealing performance of the second sealing ring 3, and the second sealing ring 3 will not be deformed, damaged, or detached from the sealing groove due to repeated squeezing and repeated flushing with water.

[0025] As a technical optimization solution of the utility model, a plurality of external flexible tensile ribs 9 distributed in a circular array are vertically arranged between the two second sealing rings 3, and one side of the external flexible tensile ribs 9 is arranged on the outer wall of the first sealing ring 2; the number of the external flexible tensile ribs 9 is not less than three.

The outer diameter of the second sealing ring 3 is larger than that of the first sealing ring 2. When the sealing ring body 1 is installed in the equipment, the second sealing ring 3 can fit the contact surface of the equipment more effectively to reduce the gap, thereby preventing fluids or substances such as liquids, gases and dust from leaking or penetrating into the interior of the equipment from the gap between the two components, thereby improving the sealing performance of the sealing ring. The spring 5 is installed in the cavity 4 of the first sealing ring 2 to enhance the stability and pressure resistance of the sealing ring, and make the sealing ring body 1 have better pressure resistance and resilience, which can greatly extend the service life of the sealing ring;

[0030] The convex ring 6 on the second sealing ring 3 can make the sealing ring body 1 extend to both sides after being squeezed, which has a good sealing effect and makes the sealing ring body 1 fit tightly with the setting groove; the pressure resistance of the first sealing ring 2 and the second sealing ring 3 is respectively improved by the support sleeve 8 and the flexible sleeve 7, and the outer flexible tensile rib 9 and the inner flexible tensile rib 10 tightly pull the two ends of the first sealing ring 2 and the second sealing ring 3 together to avoid the problem of sealing failure.
