Fully-coated two-stage shock absorber

The invention relates to the technical field of pipeline vibration isolation devices, in particular to a fully-coated two-stage shock absorber. The fully-coated two-stage shock absorber comprises a first-stage vulcanized pipe clamp assembly which fixes an upper pipe clamp and a lower pipe clamp through a pipe clamp connecting fastener so as to coat an upper lining rubber layer and a lower lining rubber layer, and further comprises rubber blocks for vibration isolation which are symmetrically arranged on the left and right sides of the bottom face of the lower pipe clamp, and a second-stage low-frequency vibration isolation assembly which is composed of a V-shaped supporting seat and fixed on the bottom faces of the rubber blocks for vibration isolation, wherein the pipe clamp connecting fastener and the mounting position of the pipe clamp connecting fastener are coated with epoxy resin anti-corrosion coatings correspondingly, and the rest parts are subjected to vulcanization treatment.
