Description

High-molecular silica gel high-temperature-resistant silica gel sealing piece Technical Field The utility model relates to the technical field of silica gel sealing elements, in particular to a high-molecular silica gel high-temperature-resistant silica gel sealing element. Background The silica gel sealing member has excellent sealing performance, can keep good sealing performance under severe environments such as high pressure, high temperature, high humidity and the like, can be used at extremely low temperature below minus 60 ℃ and at extremely high temperature above 200 ℃, does not generate phenomena such as deformation, aging, hardening and the like, has excellent weather resistance, is not easy to wet, corrosion, oxidation, acid, alkali and the like, and has the characteristics of good sealing performance, high and low temperature resistance, weather resistance and wide application field. However, conventional silicone seals suffer from the following disadvantages: The traditional silica gel sealing member has poor ageing resistance coefficient, and along with the lapse of service time, the ageing leakage phenomenon of the sealing position of the silica gel sealing member easily occurs. Disclosure of utility model The utility model aims to provide a high-molecular silica gel high-temperature-resistant silica gel sealing member so as to solve the problems that the traditional silica gel sealing member provided in the background art is poor in ageing resistance coefficient and ageing leakage at the sealing position of the silica gel sealing member is easy to occur along with the use time. In order to achieve the above purpose, the high-molecular silica gel high-temperature-resistant silica gel sealing piece comprises a sealing piece, wherein the sealing piece comprises a sealing inner ring and a sealing outer ring, a connecting groove is formed in the bottom end of the outer side of the sealing inner ring, the connecting groove is correspondingly arranged with the sealing outer ring, a plurality of first grooves are formed in the inner side of the sealing inner ring, a plurality of second grooves are formed in the surface of the sealing inner ring, and a plurality of first bumps are fixedly mounted on the inner wall of the sealing outer ring. Preferably, a plurality of second convex blocks are fixedly arranged on the surface of the sealing outer ring, the second convex blocks are arranged to improve the unevenness of the sealing outer ring, and a user can conveniently take the sealing element. Preferably, the first antislip strips are fixedly arranged in the first grooves, the unevenness of the inner wall of the sealing inner ring is increased by paving the first antislip strips, the friction coefficient between the sealing inner ring and the sealing part is improved, and the sealing stability coefficient of the sealing element is improved. Preferably, a plurality of second anti-slip strips positioned on one side of the first groove are fixedly arranged on the sealing inner ring, the second anti-slip strips are paved to increase the unevenness of the inner wall of the sealing inner ring, the friction coefficient between the sealing inner ring and the sealing position is improved, and the stability coefficient of sealing of the sealing element is improved. Preferably, the plurality of second grooves are respectively arranged corresponding to the plurality of first lugs, and the sealing inner ring and the sealing outer ring are tightly buckled together with the first lugs through the second grooves.
