Abstract

The existing nodular cast iron manhole cover has good toughness and corrosion resistance, thus prolonging the service life of the nodular cast iron manhole cover, but it is basically not equipped with anti-theft function, so the nodular cast iron manhole cover can be easily stolen by hook-like objects. In view of the above problems, this paper designs a rotary anti-theft manhole cover, which is mainly technically characterized in that the vertical rectangular shaft and the central groove rotate clockwise, so that the ends of the two toothed plates facing away from the gear slide out of the transverse cavity and are pressed into the clamping groove. The magnet has an adsorption effect on the toothed plates, and then the rotary anti-theft manhole cover is fixedly installed on the upper end face of the shaft, thus preventing thieves from stealing the manhole cover from the Jing Zuo through a hook object.
