Description

A silicone ring

technical field

The utility model relates to a sealing structure, in particular to a silicone ring with good sealing effect.

Background technique

In the prior art, sealing rings are widely used, involving static or dynamic sealing of various fluids such as oil, water, air or gas in technical fields such as mechanical seals, chemical equipment, and electrical appliances. The structure of the sealing ring is generally ring-shaped. According to the application site and the equipment installed and applied, various sealing rings have different subtle structural changes. The sealing ring is usually made of various rubbers and has a relatively low price. low merit. However, its sealing performance is not stable enough.

Contents of the invention

The purpose of the utility model is to provide a reasonably designed silicone ring, by setting a flexible ring body made of silicone material, and making structural improvements to the flexible ring body, the structure is simple, the sealing performance is good, and the fireproof silicone rubber is used The material has good fire resistance, low production cost and high production efficiency, and is worthy of popularization and application.

The technical scheme that the utility model adopts for realizing the above object is:

A silicone ring, which includes an annular flexible ring body made of silicone material, the inner diameter of the lower part of the flexible ring body is smaller than the inner diameter of the upper part of the flexible ring body, and a concave hole is arranged on the inner wall of the flexible ring body groove.

As a further improvement of the present invention, a circular protrusion is provided on the lower end surface of the flexible ring body, and the center line of the circular protrusion overlaps with the central axis of the flexible ring body.

As a further improvement of the utility model, the circular protrusion is provided with a pit for marking together.

As a further improvement of the utility model, the groove is provided at the lower part of the flexible ring body.

The beneficial effects of the utility model are as follows: the utility model has a reasonable structure. By setting a flexible ring body made of silica gel material and improving the structure of the flexible ring body, the structure is simple, the sealing performance is good, and the fireproof silica gel material is used. It has good fire performance, low production cost and high production efficiency, and is worthy of popularization and application.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
