Earthquake simulation demonstration device

The utility model belongs to the technical field of teaching demonstration equipment. The utility model particularly relates to an earthquake simulation demonstration device. The problems that an existing earthquake simulation device is complex in structural design, unbalanced in stress of all parts, prone to damage electrical apparatus elements and incapable of well simulating earthquake actionsare solved. Proposed now is the following scheme, the device comprises a base, the top of the base is in rolling connection with a first tabletop; the top of the first table board is rotationally connected with a second table board; machine bases are welded to the two sides of the top of the first table top, a servo motor is fixedly installed at the top of one of the two machine bases through a bolt, an output shaft of the servo motor is fixedly sleeved with a first chain wheel, one ends of a plurality of supports are welded to the top of the other machine base, and the other ends of the supports are rotationally conn
