Anti-theft municipal well cover detachment structure

Abstract

The invention provides an anti-theft municipal well cover detachment structure, and belongs to the field of equipment of municipal engineering, which solves the problem of poor anti-theft property of the existing well cover. The anti-theft municipal well cover detachment structure comprises a well base, a cover body, a detachment ring, a plurality of detachment rods, a hinge base and a steel plate, wherein the top part of the inner wall of the well base is provided with an annular groove; the cover body is covered on the annular groove; detachment holes are formed in the cover body; a connecting base is fixedly arranged at the inner edge of the detachment ring, penetrating holes are formed in the connecting base, and the detachment rods are penetrated into the penetrating holes in the connecting base; the hinge base is fixedly arranged on the bottom surface of the cover body; the steel plate is movably connected with a pin shaft; the pin shaft is movably connected with the hinge base; the inner wall of the well base is provided with a clamp groove; the outer end of the steel plate is positioned on the clamp groove; a tension spring is connected between the top surface of the inner end of the steel plate and the bottom surface of the cover body; each detachment hole is projected onto the top surface of the inner end of the steel plate. The anti-theft municipal well cover detachment structure has the advantage that the anti-theft property is good.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering equipment and relates to an anti-theft municipal manhole cover disassembly structure. Background technique [0002] Existing manhole covers are usually pulled up and opened with hook-shaped tools, which is difficult to disassemble, resulting in poor anti-theft performance. In the cave, a safety accident occurred. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and provide an anti-theft municipal manhole cover removal structure that increases the difficulty of disassembly, avoids random disassembly, and has a good anti-theft effect. [0004] The purpose of the present invention can be achieved through the following technical solutions: a detachable structure for anti-theft municipal manhole covers, including a circular well seat and a circular cover body, the top of the inner wall of the well seat is ...
