2. Vibration isolation function: the connecting cover connected with the protected object and the connecting cavity connected with the non-protected object or the ground are isolated in a vertical flexible mode through the elastic body. The elastic body mainly plays a role in adjusting the vertical natural frequency of the protected object, and the elastic body isolates vibration through vertical reciprocating deformation of the elastic body.
Because the rubber ring is made of high-molecular elastic materials, the extrusion amount of the rubber ring is controlled within a set range, the vertical rigidity is small, and the transmission of vibration and sound is isolated; the axial O-shaped ring can realize a sealing function, and the vertical rigidity of the rubber ring and the axial O-shaped ring can be ignored relative to the vertical rigidity of the elastic body.
