[0030] As Figures 1-7As shown, it shows an adaptive seismic isolation support in an embodiment of the application, including the upper support plate 1 and the lower support plate 2, the surface of the upper support plate 1 is provided with a seismic isolation device for the isolation effect of the support, the seismic isolation device includes an anchoring assembly 31, the anchoring assembly 31 is fixed through the surface of the upper support plate 1, the inner wall of the upper support plate 1 is slidingly installed with a sliding rod 32, the surface of the sliding rod 32 is fixedly installed with a damping spring 33, the bottom of the upper support plate 1 is provided with an upper seat plate 34, the top of the lower support plate 2 is provided with a middle steel plate 35, the upper seat plate 34 and the middle steel plate 35 are provided with a seismic isolation plate 36, the top of the lower support plate 2 is fixedly installed with a telescopic spring rod one 37, the top of the lower support plate 2 is slidingly installed with a buffer plate 38, the surface of the upper seat plate 34 is provided with a shear pin 39, the upper seat plate 34 is pulled and buffered by the shear pin 39 and the energy absorption effect.

[0031] The surface of the upper seat plate 34 is provided with an inner recessed groove one for the friction sliding of the seismic isolation plate 36, the surface of the middle steel plate 35 is provided with an inner recessed groove two for the friction sliding of the seismic isolation plate 36, the bottom of the middle steel plate 35 is made of a polytetrafluoroethylene plate, and the middle steel plate 35 slides through the low friction coefficient of the bottom polytetrafluoroethylene plate.

[0032] The free end of the telescopic spring rod one 37 is fixedly connected with the buffer plate 38, the surface of the buffer plate 38 is provided with an arc surface one for abutting with the middle steel plate 35, when the middle steel plate 35 loses the effect of the seismic isolation plate 36, at this time the telescopic spring rod one 37 deforms and restores to push the buffer plate 38 to move.

[0034] In the present example, the device is installed in the area where vibration reduction and isolation is required. When the building vibrates under external force, the sliding of the intermediate steel plate 35 and the vibration reduction and isolation plate 36 in the middle of the intermediate steel plate 35 and the vibration reduction and isolation plate 36 at this time, the vibration reduction and isolation plate 36 slides and drives the intermediate steel plate 35 to slide to offset the external force, reducing the structural damage or abnormal function of the device caused by vibration impact, at the same time, the intermediate steel plate 35 slides through the low friction coefficient of the bottom polytetrafluoroethylene plate, which adapts to the vibration while providing rigid support to the upper support plate 1.
