[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] The following is an explanation of the preferred embodiments of the device of the utility model.

[0022] See also Figure 1-3 As shown, the novel high-rise anti-seismic damper includes a shock absorbing box 1. The shock absorbing box 1 is the main structure of the entire damper, which plays the role of accommodating and protecting the internal components and provides certain structural strength and stability. The bottom of the shock absorbing box 1 is provided with a bottom plate 2, and the top of the shock absorbing box 1 is provided with a damper body 3. There are four damper bodies 3, which are evenly distributed at the four corners of the top of the shock absorbing box 1. The side of the damper body 3 is provided with a screw rod 4. There are four screw rods 4, which are staggered and distributed at the side of the damper body 3. The rods of the damper body 3 and the screw rod 4 are vertically penetrated by a plurality of anti-seismic plates 5, and are fixed between the plurality of anti-seismic plates 5 by nuts 8. The outer periphery of the damper body 3 is provided with a tightening spring 6, which is fixedly connected by a spring tightening flange 7. The tightening spring 6 can produce elastic deformation when the damper body 3 is vibrated, and further absorb and consume vibration energy. The setting of the spring tightening flange 7 ensures the stability and reliability of the tightening spring 6, and prevents it from shifting or failing during operation. A connecting column 9 is provided at the top center of the shock-absorbing box 1 for connecting and transmitting shock waves on several seismic anti-vibration plates 5. Connecting steel plates 10 are provided at four directions on the top of the seismic anti-vibration plate 5. One side of the connecting steel plate 10 is fixedly connected with a side wall 11. The setting of the connecting steel plate 10 and the side wall 11 enhances the structural strength and stability of the seismic anti-vibration plate 5 and improves its shock absorption capacity.

[0023] Among them, the uniform distribution of the four damper bodies 3 ensures uniform force and improves the overall stability. The setting of the screw 4 enables the seismic plate 5 to be firmly fixed on the damper body 3 to form a stable structural system. Specifically, the seismic plate 5 itself has excellent seismic resistance and can effectively absorb and disperse the vibration energy generated by external forces such as earthquakes. By stacking multiple seismic plates 5, the overall seismic resistance can be further increased to make the structure more stable. Secondly, the setting of the damper body 3 further strengthens this seismic effect. The damper body 3 can absorb and consume vibration energy through its internal mechanism and reduce the transmission of vibration in the structure. When the telescopic rod of the damper body 3 penetrates to the top of the stacked seismic plate 5, it can work together with the seismic plate 5 when vibration occurs to absorb and disperse vibration energy in a coordinated manner, further improving the seismic performance of the entire structure.

[0024] Furthermore, a guide rail 101 is provided at the bottom of the inner cavity of the shock absorbing box 1, a fixed slider 102 is provided on the guide rail 101, a fixed seat 104 is connected to the top of the fixed slider 102, a movable disc 103 is slidably connected in the fixed seat 104, and an elastic steel plate 106 is fixedly connected to the inner side of the shock absorbing box 1 through a buffer telescopic rod 105, wherein the top of the fixed seat 104 is fixedly connected to the top plate of the shock absorbing box 1, and the elastic steel plate 106 is arranged around the outer wall of the fixed seat 104. Specifically, when an earthquake occurs, the movable disc 103 slides in the fixed seat 104, thereby driving the elastic steel plate 106 to contact the fixed seat 104, thereby squeezing the elastic steel plate 106, so that the elastic steel plate 106 can be used to weaken earthquake waves from multiple directions under the cooperation of the elastic steel plate 106 and the buffer telescopic rod 105, thereby improving the shock absorption effect, wherein the setting of the guide rail 101 also facilitates the movement of the movable disc 103.
