ABSTRACT:
An anti shock device has a base plate and a top plate, at least one pair of support racks are mounted between the top plate and the base plate. At least one adapter is mounted between the support racks. The adapter has a curved rail defined therein, and the support racks also have curved rails defined therein which curves opposite to that of the adapter. A rolling shaft is mounted through the curved rails. In addition, a damping layer is provided on the top plate or base plate as well as support racks and rolling shafts. When the anti shock device is subjected to the earthquake, a relative displacement will reduce the horizontal vibrations and the damping layer will reduce the vertical vibrations.
