A plug lock for locking electric plugs is disclosed. The device comprises a case having a shaft. The shaft has a pair of inverted U-shaped cut portions that pivot outwardly. A lock gear is rotatably disposed within the shaft and engages the cut portions pushing them outwardly. A block cap is slidably disposed on the shaft. In its extended position, the block cap blocks the electric prongs\access to an electric socket. In this position, the lock gear is rotated so that the cut portions extend outwardly, preventing the lowering of the block cap. Lock drive means control rotation of the lock gear.

A plug lock for preventing the prongs of a plug from being inserted into a receptacle comprising: a base; a shaft having a first flange on one end extending outwardly from the base; a first cut portion, located along the length of the shaft and attached to the shaft at a first attachment point proximate the base, that pivots outwardly from the first attachment point; a second cut portion, located along the length of the shaft opposite the first cut portion and attached to the shaft at a second attachment point, that pivots outwardly from the second attachment point; a block cap, slidably connected to the shaft and moving between an unlocked position wherein the prongs are exposed to a locked position wherein the prongs are enshrouded by the block cap and, having a second flange on one end that engages the first flange to prevent the block cap from being expelled off of the shaft in the locked position; a lock gear, having a first end and a second end such that when the lock gear is perpendicularly to the travel path of the block cap the first end engages and pushes the first cut portion outwardly and the second end engages and pushes the second cut portion outwardly thereby the first cut portion and the second cut portion each engage the second flange and retain the block cap in the locked position, rotatably disposed within the interior of the shaft; and a drive means for engaging and controlling rotation of the lock gear.
