Anti-theft municipal manhole cover

Abstract

The invention discloses an anti-theft municipal inspection well cover. The anti-theft municipal inspection well cover comprises a well seat and a well cover body. A bearing seat is horizontally constructed on the inner wall of the upper end of the well seat. A bearing rod is perpendicularly welded to one side of the bearing seat. The bearing rod is sleeved with a strong spring. The fixed end of the well cover body is rotatably arranged on the bearing rod in a sleeving mode. The well cover body abuts against the strong spring. The side, far away from the fixed end, of the well cover body is provided with a first-stage vertical slot and a first-stage horizontal slot. A handle is rotatably arranged in the first-stage vertical slot. According to the anti-theft municipal inspection well cover,the well cover body and the well seat are integrated to improve the stability of the well cover body and the well seat; the well cover body and the well seat are mounted in a secret mode through a built-in plug pin and a built-in limiting pin to be prevented from being found easily by a thief. Limitation to the plug pin is stopped by pressing the well cover and adsorbing a fixed magnet and the limiting pin through a movable magnet so that the thief is not likely to found the limiting pin. A person cannot rotate the plug pin through the handle, so that the opening difficulty of the well cover is improved, and the anti-theft protection effect on the well cover is achieved.

Description

technical field [0001] The invention relates to the technical field of municipal inspection well infrastructure construction, in particular to an anti-theft municipal inspection well cover. Background technique [0002] In recent years, my country's urbanization process has been accelerating, and at the same time, more attention has been paid to the infrastructure construction of ground and underground drainage channels. In order to facilitate the daily maintenance and management of underground drainage channels and ensure the smoothness of municipal roads, it is necessary to set up inspection wells, and a large number of inspection well covers need to be added on the surface to ensure the overall rationalization of municipal construction. [0003] Manhole covers installed on urban roads and sidewalks need to withstand repeated rolling, so it is necessary to ensure that the manhole covers themselves have a hard structure. Most of these manhole covers are made of rolling-resi...
