However, due to the difference in material selection and structure, the cost performance of gaskets is uneven, the service life and durability are often relatively low, and frequent replacement and inspection are required, especially for some equipment with relatively large vibration, the loss of gaskets increases
Due to the damaged performance of the gasket, leakage and breakage often occur, which greatly reduces the safety performance of electronic equipment and causes hidden dangers to the production process
The current gaskets made of a single material are difficult to meet the production needs in terms of performance and service life, and the gasket structure and materials need to be developed and improved

Abstract
The invention discloses a novel seal washer structure. The seal washer comprises a washer body and an inner ring, wherein the washer body is provided with an annular groove and an inner bore; the inner ring is provided with another annular groove; and the washer body and the inner ring are fixed in a binding mode. A washer body and inner ring double-layer structural design is applied to the washer, and because the washer body and the inner ring are made of different materials with different performances, the sealability of the seal washer can be improved by using the washer body and the inner ring together; meanwhile, the inner ring can be prepared from various materials so that the inner ring has various functions and the application range of the seal washer is widened; in addition, because of the design of the annular groove on the inner ring, a certain pressure difference between the inside and the outside of the inner ring can be generated when the inner ring is under the action of a force, thereby further improving the leakage prevention capacity of the seal washer and ensuring the excellent sealiability of electronic equipment.
Description
technical field [0001] The invention relates to a sealing gasket structure, in particular to a new gasket structure designed with an inner and outer double-layer structure, and belongs to the technical field of electronic components. Background technique [0002] A gasket is a mechanical seal between two objects, usually to prevent leakage under pressure between the two objects. Since machined surfaces are never perfect, irregularities can be filled with gaskets. Gaskets are usually made of sheet materials such as paper pads, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymers such as polyvinyl chloride. [0003] There are many kinds of gaskets on electronic equipment, which are shockproof, moistureproof, waterproof, breathable, ozone resistant, weather aging resistant, weak acid and weak alkali resistant, etc., and are widely used. However, due to the difference in material selection and structure, the cost performance of ...
