Damping device of bridge structure

The utility model relates to the technical field of bridge shock absorption, in particular to a damping shock absorption device of a bridge structure, which comprises a first shock absorption seat, a second shock absorption seat, a rubber block, a support rod and a connecting assembly, the two ends of the rubber block are respectively and fixedly connected with the first shock absorption seat and the second shock absorption seat, and the first shock absorption seat or the second shock absorption seat is provided with a blind hole. One end of the rubber block is fixedly connected with the first damping seat or the second damping seat, the other end of the rubber block is inserted into the blind hole, and a gap is formed between the blind hole and the supporting rod. During use, the first damping seat and the second damping seat are fixed to a bridge body and a bridge pier through the two connecting assemblies correspondingly, when the bridge vibrates, movement generated by the bridge in the horizontal directio
