The cross-arranged long plates respectively support the top of the inner wall of the mounting shell, making the mounting shell more stable during use. When subjected to impact, the vertical impact is consumed by the limiting damping rod generated on the plug rod, thereby reducing the vertical impact force on the long plate, support base and rotating sleeve. At the same time, the vibration energy generated in the vertical direction is dispersed by the limiting damping rod on the plug rod, increasing the overall fatigue resistance.

The bottom of the fixed groove plates 6 is fixedly connected to the bottom of the inner wall of the mounting shell 2. A first damping rod 7 is fixedly connected to the top of the fixed groove plates 6, and the top of the first damping rod 7 is fixedly connected to the top of the inner wall of the mounting shell 2. Two movable grooves are formed on the surface of the fixed groove plates 6. A long rod 8 is installed inside the movable groove. Two symmetrically arranged movable blocks 9 and two symmetrically arranged pressing seats 10 are sleeved on the outside of the long rod 8. One side of the movable block 9 is connected to the inner wall of the movable groove by a limiting spring, which is used to convert the impact force through the limiting spring. One side of the pressing seat 10 is connected to the inner wall of the movable groove by a return spring, which allows the pressing seat 10 to return to its initial state when moving. The surface of block 9 is connected to the surface of extrusion seat 10 by a connecting spring. The top of extrusion seat 10 is rotatably connected to a stop rod 11. The top of the stop rod 11 is rotatably connected to two mounting blocks. The mounting blocks are fixedly connected to the top of the inner wall of the mounting shell 2.

[0032] The implementation principle of a pot-type seismic isolation bearing in this application embodiment is as follows: When subjected to impact, the device will vibrate. The force generated by the vibration will be transmitted to the interior of the mounting shell 2, causing the moving block 9 to move along with the movable block 13. During this process, the elastic action of the limiting spring, the return spring and the connecting spring will convert the energy generated by the vibration into elastic potential energy, thereby consuming the vibration energy generated during the impact. At the same time, in the vertical direction, the vibration generated in the vertical direction will be consumed by the support damping rod 5, the first damping rod 7 and the second damping rod 12, so as to reduce the vibration energy generated during the impact. By converting the energy during the impact into elastic potential energy for consumption, the seismic resistance of the device is improved.

[0033] The four connecting slot plates 15 enable the support base 16 to support the top of the mounting shell 2 via the long plate 17 and the rotating sleeve 18. The four sets of cross-arranged long plates 17 respectively support the top of the inner wall of the mounting shell 2, making the mounting shell 2 more stable during use. When subjected to impact, the vertical impact will be consumed by the limiting damping rods generated on the insert rods 20, thereby reducing the vertical impact force on the long plate 17, support base 16 and rotating sleeve 18. At the same time, the vertical vibration energy is dispersed by the limiting damping rods on the four insert rods 20, increasing the overall fatigue resistance.
