The present invention provides a distribution board earthquake-proof apparatus which automatically supplies air to an air tube upon occurrence of an earthquake and effectively and immediately decreases vibration in vertical and horizontal directions, thereby safely and reliably supporting a distribution board and periodically removing dusts which exist in an internal space of a distribution board enclosure. To implement this, the distribution board earthquake-proof apparatus according to the present invention comprises: a frame which is installed on a bottom surface of a distribution board and in which a space is formed; an air tube which is installed inside the frame and is expended by a pressure of air supplied from a control means to decrease vibration; an air tube fixing frame which covers a top surface of the air tube, wherein a lower end of the air tube fixing frame comes into contact with an internal space bottom of the frame and is raised up according to expansion of the air tube to release the contact; and a vibration proofing spring having one end fixed to the bottom surface of the distribution board and the other end passing through a hole formed on the top end of the frame and fixed to the top surface of the air tube fixing frame, so as to decrease the vibration again. |
