Abstract

The invention discloses a dustproof sealing ring, which includes a main oil seal, and is characterized in that the main oil seal includes a metal skeleton, an annular sealing spring and a sealing rubber, the sealing rubber is arranged inside the main oil seal, and one end of the sealing rubber There is a first sealing part for clamping and sealing the metal frame and the other end is provided with a second sealing part for clamping and sealing the annular sealing spring, and the outer wall of a secondary oil seal is tightly engaged in the metal frame of the main oil seal. Adding a secondary oil seal on the inner side of the main oil seal can effectively prevent impurities in the sealing medium, and can properly reduce the pressure shock in the cavity and improve the service life of the sealing ring. It is suitable for occasions that require dust protection on both sides and oil sealing in the middle For example, it is used to seal water and detergent in washing machines.

Description

technical field [0001] The invention relates to a dustproof sealing ring. Background technique [0002] The traditional sealing ring can only perform the function of sealing, and cannot be used in some occasions where oil is sealed in the middle and dust protection is required on both sides. Contents of the invention [0003] In view of the above problems, the present invention provides a dust-proof sealing ring, which is suitable for the occasion where oil is sealed in the middle and dust-proof is required on both sides. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions: [0005] A dust-proof sealing ring, including a main oil seal, characterized in that the main oil seal includes a metal skeleton, an annular sealing spring and a sealing rubber, an outer diameter rubber layer is arranged on the outside of the metal skeleton, and t...
