A vertical buffer mechanism is connected between the two horizontal buffer mechanisms. The horizontal buffer mechanism can buffer horizontal thrusts in different directions.

[0022] In this embodiment, the horizontal buffer mechanism includes a magnetic sliding block 2, an angle adjustment block 3, a sliding hinge shaft 7 and a connecting rod 4, a slider is provided on one side of the magnetic sliding block 2, the magnetic sliding block 2 is connected to the sliding groove 1.1 in the top plate 1 through the slider, the two ends of the magnetic sliding block 2 are respectively attracted to one end of the adjacent magnetic sliding block 2, an angle adjustment block 3 is fixedly provided on the side of the magnetic sliding block 2 away from the slider, the angle adjustment block 3 is hinged to one end of the connecting rod 4, the other end of the connecting rod 4 is hinged to the end of the adjacent connecting rod 4 away from the angle adjustment block 3 through the sliding hinge shaft 7, one end of the sliding hinge shaft 7 abuts against the top plate 1, and the other end is provided with a first block that is slidably connected to the vertical buffer mechanism; the magnetic sliding block 2 will slide along the sliding groove 1.1, and the magnetic sliding block 2 will reduce the sliding displacement due to the influence of the magnetic attraction, thereby buffering the thrust, and the magnetism between the connecting rod 4 and the mutually connected magnetic sliding blocks 2 can be used to correct the deviation, so as to prevent the magnetic sliding block 2 from detaching from the shock absorbing device;

[0023] The magnetic sliding block 2 is specifically an arc-shaped sliding block, and strong magnets are arranged at both ends of the interior of the arc-shaped sliding block, and the mutual attraction between the magnetic sliding blocks 2 is achieved through the strong magnets.

[0024] In this embodiment, a hinge hole 3.2 is provided on the angle adjustment block 3, and a hinge column 3.1 is provided on the angle adjustment block 3. One end of the hinge column 3.1 passes through the connecting rod 4 and the top end of the angle adjustment block 3 in sequence and extends into the hinge hole 3.2, and both ends of the hinge column 3.1 are connected to a second clamping block.

[0025] In this embodiment, the vertical buffer mechanism includes an upper shell 5, a lower shell 6 and an elastic buffer mechanism. The outer walls of the upper shell 5 and the lower shell 6 are both provided with a T-shaped slot, and a second damper is provided in the T-shaped slot, which is slidably connected to the sliding hinge shaft 7 in the horizontal buffer mechanism through the T-shaped slot. One end of the second damper is fixedly connected to the inner wall of the T-shaped slot, and the other end is abutted against the sliding hinge shaft 7 along the extension direction of the T-shaped slot.

When the upper shell 5 and the lower shell 6 are directly rotatably connected to the sliding hinge shaft 7, no T-shaped slide groove and the second damper are provided.

[0026] In this embodiment, the elastic buffer mechanism includes a rubber column 9 and a first damper 8. The rubber column 9 is fixed to the bottom end of the inner wall of the lower shell 6.

The first damper 8 and the rubber column 9 can buffer the vertical force applied to the building.

[0027] Working principle: When in use, first fix the top plates 1 at both ends of the seismic isolation device on the building. When the building receives a horizontal thrust, the magnetic sliding block 2 slides. When it slides to a certain state, the magnetic sliding block 2 will stop sliding due to the suction force of the adjacent magnetic sliding block 2, thereby buffering the horizontal thrust of the building. When the building receives thrusts in different horizontal directions, the mutually hinged connecting rods 4 can push the thrust to the sliding direction of the magnetic sliding block 2, realize the change in the sliding direction, and improve the buffering effect; in addition, when the building receives a vertical force, the first damper 8 and the rubber column 9 can perform vertical buffering to improve the buffering effect, and in extremely cold weather, insulation materials can be set in the upper shell 5 and the lower shell 6 in the vertical buffer mechanism to ensure the temperature inside the upper shell 5 and the lower shell 6 to avoid the influence of extremely cold weather on the rubber column 9.
