The utility model relates to a height-adjustable anti-seismic support, which belongs to the technical field of bridge supports and comprises an upper connecting steel plate, and a buffer lead column is fixedly mounted in the middle of the bottom of the upper connecting steel plate. When the anti-seismic support needs to be adjusted, the bearing threaded rod is synchronously rotated to be rotated into the first lead screw nut, so that the distance between the lower connecting steel plate and the middle steel plate can be adjusted, and the overall height of the anti-seismic support is adjusted; according to the height-adjustable anti-seismic support, the mounting frame can bear a middle steel plate and equipment on the top of the middle steel plate through the bearing rods, so that the anti-seismic support can be more stable, a buffer lead column and a rubber pad arranged in a rubber sleeve can rapidly dissipate energy of bridge vibration, and the height of the height-adjustable anti-seismic support can be rapi
