Since humans cannot accurately predict the occurrence of earthquakes, it is particularly important to prevent and mitigate earthquake disasters. However, the existing cultural relic shock isolation platform is usually installed in the cultural relic display cabinet and supported at the bottom of the cultural relic. Under the action of earthquake, it effectively absorbs seismic waves, thereby isolating seismic waves and protecting cultural relics.

When an earthquake occurs, under the influence of the earthquake transverse wave, the cultural relic cabinet occurs horizontal displacement in the front-back or left-right direction relative to the bottom plate 1, the top plate 3 moves along with the cultural relic cabinet, and the intermediate plate 2 cooperates to make corresponding horizontal movement. The adaptive displacement reduces the damage of the earthquake force on the cultural relic cabinet.
