Abstract

The invention provides an anti-overturning vibration isolator. A sliding sleeve with L-shaped cross section is arranged in the vibration isolator in a sleeved mode; the upper end face portion of the plane of the sliding sleeve supports a split ring; and the lower end of the inner plane of the sliding sleeve is connected with a cap through a middle sliding piece, a belleville spring and a lower sliding piece. A horizontal movement clearance exists between the upper end of the cylindrical inner wall of the sliding sleeve and the belleville spring. A small fit clearance exists between the lower end of an outer cylinder of the sliding sleeve and the inner wall of a base. According to the anti-overturning vibration isolator, the dip angle of the central axis of the vibration isolator is controlled to be within 2 degrees to 5 degrees by controlling the fit clearance between the sliding sleeve and the inner wall of the base, therefore, the anti-overturning capacity of the vibration isolator is improved, and the buffering effect of the vibration isolator can be adjusted according to using demands.
