Abstract

The invention discloses an inspection well lid facilitating theft prevention. The inspection well lid comprises a well seat and a well lid body, clamping grooves are formed in the inner wall of the well seat in a concave mode, an accommodating cavity is horizontally formed in the well lid body, a sleeve with the upper end being not provided with a sealing opening is welded to the upper end of the accommodating cavity, a vertical rod is vertically welded into the middle end of the accommodating cavity, a rotating disc is rotationally arranged at the middle end of the vertical rod in a sleeving mode, three connecting grooves are formed in the rotating disc in circumferential array and concave modes, and a supporting spring is rotationally arranged at the top end of the vertical rod. According to the inspection well lid, a suspension cover is arranged in a suspended mode, so that the suspension cover and an opening and closing structure for directly opening the well lid are mounted in a differentiated mode, the purpose of opening the well lid is achieved through rotation of the suspension cover and the rotating disc, a well lid opening switch is arranged in a hidden mode advantageously, thus the opening difficulty is improved, and the theft preventing function is effectively achieved; and by arranging the sleeve, the suspension cover is protected through a threaded cover in threaded connection with the sleeve, so that repeated extrusion of ground surface external force to the suspension cover is avoided, and the service life of the well lid is prolonged advantageously.

Description

technical field [0001] The invention relates to the technical field of road administration inspection shaft infrastructure construction, in particular to an inspection shaft cover which is convenient for anti-theft. Background technique [0002] With the continuous acceleration of the urbanization process, the infrastructure construction of the ground and underground drainage channels is also increasing. Among them, in order to facilitate the daily maintenance and management of the underground drainage channels, it is necessary to open inspection wells, and on the surface A large number of manhole covers need to be added on the road to ensure the smooth flow of the road. [0003] For the manhole covers arranged on urban roads and sidewalks, due to the need to bear a large amount of rolling, for this reason, most of these manhole covers are made of rolling-resistant cast iron. However, manhole covers made of cast iron generally adopt a simple snap-fit ​​installation method, ...
