AI Technical Summary

Technical Problem

The manhole covers used in existing municipal projects are easily stolen, resulting in the manhole being open, losing public property and affecting traffic.

Method used

A manhole cover locking structure is designed, including a locking mechanism and limiting assembly, and the turntable is driven by magnets to rotate, and the manhole cover locking and unlocking is achieved through the combination of the lever and the T-shaped limiting rod, and the friction force is reduced through the ball universal ball. Make sure the manhole cover is not easily stolen.

Benefits of technology

Effectively prevent the manhole cover from being stolen, ensure that the manhole cover is in a locked state, and can only be unlocked with the cooperation of magnets, reducing the risk of manhole cover being stolen and ensuring the safety of public facilities.

Abstract

The utility model relates to the technical field of well lids, in particular to a well lid locking structure which comprises a mounting seat, a well lid and the like. A well lid is placed on the upper portion of the installation base, a plurality of assembly holes are formed in the upper portion of the installation base in the circumferential direction, the locking mechanism used for locking the well lid is jointly arranged at the bottom of the well lid and the lower portion of the installation base, and a limiting assembly is arranged on the locking mechanism and used for keeping the well lid locking state of the locking mechanism. By arranging the locking mechanism and the limiting assembly, the magnet drives the rotating disc to rotate, the rotating disc pushes the T-shaped limiting rod to be matched with the fixing block through the shifting rod to achieve locking and unlocking of the well lid, the limiting mechanism enables the rotating disc not to rotate easily, and therefore the T-shaped limiting rod is kept clamped with the fixing block. Common people do not know that the well lid needs to be unlocked through cooperation of the magnet, and therefore it is guaranteed that the well lid is not prone to being stolen.
