High damping rubber seismic isolation bearing

This utility model provides a high-damping rubber seismic isolation bearing, relating to the field of rubber bearing technology. It includes: a first support plate; and a seismic isolation assembly, which includes a screw fixed to the first support plate. In normal use, the first support plate bears the load of the superstructure. When vibration occurs, the seismic isolation assembly plays a major role in vibration isolation. The high-damping rubber dissipates a large amount of vibration energy through its viscous hysteresis characteristics, while the low-stiffness rubber provides greater horizontal deformation capacity, allowing the bearing to have a certain displacement in the horizontal direction. By rotating the nut, the height of the bearing can be adjusted to adapt to different working conditions. The anti-overturning assembly ensures the stability of the bearing during vibration. The limiting rod slides within the hollow tube, limiting the horizontal displacement range of the bearing and preventing excessive offset. The limiting post is within the limiting seat, preventing the bearing from overturning. Thus, this seismic isolation bearing can effectively reduce the impact of vibration on the superstructure and protect structural safety.
