Seismic device for distributing board using the seismic spring

The present invention relates to a seismic device for a switchgear using a seismic spring, and more particularly, to prevent damage to the switchgear due to torsion or inclination of the switchgear due to vibration or shock caused by earthquake or the like. The seismic device for the switchgear using the seismic spring to easily adjust the height and level of the switchgear with different weights is provided in the seismic device installed in the lower frame of the switchgear. A cylinder with an open upper surface protrudes, and a screw hole is formed at the center bottom surface of the cylinder, but a through hole formed with a predetermined space is formed at a lower end of the screw hole, and a fixed plate and a fixed plate having a circular protrusion formed on the outer circumferential surface of the cylinder. In the screw hole formed in the center of the cylindrical bottom The elastic adjustment screw is installed to move up and down, but the upper side of the elastic adjustment screw protrudes into the cylinder is provided with a pressing member of a circular plate, the upper side of the pressing member and the elastic adjustment member is installed with a seismic spring The bottom of the cylindrical frame is open to the inner cylinder of the fixed plate "c" shaped cylindrical frame is provided with an absorbing means to prevent the impact on the inner side of the cylindrical frame, the insertion portion is formed so that the circular projection of the fixed plate is inserted and the outer peripheral side A screw groove is formed in the center and a screw groove of the support member has a structure including a switchboard and a fastening bolt for fastening and moving up and down.
