[0019] Preferably, the connecting rings are linearly arranged in the inner side of the sealing ring, and the connecting rings are bonded with the sealing ring.

[0020] Preferably, the inner ring is located in the inner side of the sealing ring.

[0021] Compared with the prior art, the sealing silica gel ring has the following advantages and beneficial effects:

[0022] This double-layered waterproof silicone sealing ring, through the coordinated arrangement of a first outer ring, a second outer ring, a connector, a sealing ring, an inward-facing port, a connecting ring, and an inner ring, provides excellent overall waterproof performance. From the outside in, it consists of an outer ring, a sealing ring with an inward-facing port, and multiple inner rings. From top to bottom, it comprises a first outer ring, a sealing ring, a connector, a second outer ring, and a sealing ring, forming a three-dimensional, multi-layered sealing structure with multiple lines of defense. Even if one line of defense is damaged, the others can continue to function. The sealing ring and outer ring are specifically inserted into the area to be sealed. Simultaneously, multiple compressible connecting rings are connected to the inner side of the sealing ring, and the inner side of each connecting ring is connected to an inner ring. The inner ring has a C-shaped cross-section. During installation, the inner ring acts like multiple tentacles, tightly gripping the area to be sealed, further enhancing the sealing effect. Its tentacle-like structure allows it to fit tightly against the area to be sealed, forming a seal without any blind spots.

[0023] This sealing silicone ring is suitable for sealing various shapes and sizes. It provides a reliable seal in both static and dynamic environments.
