Bridge anti-seismic support

The utility model relates to the technical field of bridge supports, and discloses a bridge anti-seismic support which comprises a base. According to the bridge anti-seismic support, the telescopic damping ball installed at the bottom of the inner cavity of the supporting cross beam rotates in the ball seat, so that the supporting cross beam and a bridge installed on the top of the supporting cross beam are prevented from generating too large displacement when receiving external shaking pressure; a first damping rod mounted at the bottom of an inner cavity of the supporting cross beam rotates at the top of the base, so that the effect that the supporting cross beam is shrunk under shaking pressure, and then the shaking pressure is relieved is achieved; through a spring and a second damping rod which are mounted at the bottom of a limiting clamping plate, the effect that the spring and the second damping rod are shrunk to relieve shaking pressure borne by the two sides of the supporting cross beam is achieved;
