Spring-constrained liftable rubber shock insulation support

The utility model provides a spring-constrained liftable rubber shock insulation support, and belongs to the technical field of civil engineering. The device comprises a rubber support, a lower flange plate, a common cylindrical helical compression spring, a lower anchor bolt, a lower anchor bolt base plate, a lower anchor bolt nut, a lower positioning plate, a lower embedded sleeve, a lower anchor bar, an upper flange plate, an upper anchor bolt, an upper anchor bolt base plate, an upper anchor bolt nut, an upper positioning plate, an upper embedded sleeve and an upper anchor bar. The core of the utility model is that the common cylindrical helical compression spring is connected between the lower flange plate and the lower anchor bolt base plate, and the rubber support can be lifted off by using the elastic constraining force of the common cylindrical helical compression spring, so as to buffer and reduce the internal damage to the rubber support caused by the vertical pulling force generated by an earthqua
