Abstract
The invention discloses an anti-theft inspection well cover. The anti-theft inspection well cover is provided with a rotating disc with an irregular concaved locking groove and a rotating rod used in cooperation with the rotating disc, wherein the rotating disc is arranged on the surface of the inspection well cover. The irregular concaved locking groove is matched with an irregular protrusion to achieve rotation of the rotating disc, and accordingly a connection rod mechanism arranged at the bottom of the inspection well cover of the rotating disc is driven to achieve locking or opening of the inspection well cover. The anti-theft inspection well cover has the advantages of being simple in structure, low in manufacturing process requirement and the like, is also suitable for improvement of an ordinary inspection well cover and has good social benefits.
