Abstract
The utility model relates to a manhole cover guarding device applied to such industries like the highway, the railway, the municipal power, the telecommunication, the coal gas, the tap water and so on. The utility model is composed of a tapered end and an unlocking device, the tapered end is arranged on the near edge part of the back of a manhole cover, the forward rotation and the backward rotation of a special unlocking device is used to drive a control plate in the tapered end to shift so that the compression and the recovering of a spring in the tapered end can drive a bolt to shift, thereby realizing the opening and the closing of manhole covers in time. The device has good guarding effect, is easy to be arranged and used, and has wider application range, larger social and economic benefit.
Description
Technical field
The utility model relates to industry society communal facility---a kind of anti-theft devices of manhole cover such as highway, railway, municipal electric power, telecommunications, coal gas, tap water.
