[0024] Reference below Figure 1 and Figure 2 The anti-disturbance viscous damper according to the embodiment of the present invention is described.

[0025] The anti-disturbance viscous damper of the embodiment of the utility model comprises a cylinder body 100 and a first component. A piston 110 is arranged in the cylinder body 100 for transverse sliding. A first connecting rod 111 is arranged on the left side of the piston 110. The first connecting rod 111 passes through the left wall of the cylinder body 100 in the transverse direction. The first component comprises two cables 120. The two cables 120 are respectively arranged on the left and right sides of the piston 110. The cables 120 are arranged transversely. The cables 120 have a head end and a tail end. The head end and the tail end are respectively connected to the cylinder body 100 and the piston 110.

[0026] For example, Figure 1As shown, the cylinder body 100 is in a transversely arranged cylindrical shape, and the left and right ends of the cylinder body 100 are both provided with end walls, and the two end walls are respectively called the left wall and the right wall. The left wall is provided with a first sliding hole for the first connecting rod 111 to pass through, and a sealing ring can be provided between the hole wall of the first sliding hole and the first connecting rod 111 for sealing. Damping oil is provided in the cylinder body 100, and a piston 110 is provided in the cylinder body 100. The outer diameter of the piston 110 is slightly smaller than the inner diameter of the cylinder body 100, or the piston 110 is provided with a transversely arranged through hole, so that the damping oil in the space on the left side of the piston 110 and the space on the right side of the piston 110 are in contact with each other. The damping oil in the space can circulate mutually; the right end of the first connecting rod 111 is fixedly connected to the piston 110, and the left end of the first connecting rod 111 passes through the first sliding hole, so that the first connecting rod 111 and the cylinder body 100 are relatively slidably connected; the two cables 120 are respectively called the first cable and the second cable, the first cable is arranged on the left side of the piston 110, and the second cable is arranged on the right side of the piston 110, the left end of the first cable is its head end, connected to the left wall, the right end of the first cable is its tail end, connected to the piston 110, the left end of the second cable is its tail end, connected to the piston 110, and the right end of the second cable is its head end connected to the right wall.

During a large earthquake, the piston 110 applies a large lateral force to the cylinder body 100 through the cable 120, and the cable 120 is broken, so the piston 110 and the cylinder body 100 can be relatively displaced, the damper expands and contracts, and the vibration energy is consumed; in addition, when the lateral force in only one direction is large, only the cable 120 on one side of the piston 110 rod is broken, while the cable 120 on the other side can maintain the integrity of the structure, so that the damper can absorb part of the vibration while maintaining the stability of the building to a certain extent.

[0028] In some embodiments of the utility model, the head end penetrates the cylinder body 100 in the transverse direction, and the head end is provided with an end block 121, and the end block 121 is arranged on the outside of the cylinder body 100.

The cable 120 and the end block 121 can be an integral component for easy production.

[0029] In some embodiments of the present invention, the two cables 120 are collinear, so that the pulling forces applied by the two cables 120 to the piston 110 are in a straight line, the force on the piston 110 is relatively balanced, and the structure is stable.
