Problems solved by technology

Because the cover is only laid on the base, it is often stolen by criminals with serious consequences
In order to prevent the cover plate from being stolen, a class of anti-theft manhole cover has appeared on the market, and it usually adds an anti-theft lock between the cover plate and the base. Its structure is complex and its production cost is high
At the same time, parts such as the keyhole of the added anti-theft lock are prone to rust when they are not moved for a long time, making it difficult to operate when the cover needs to be unlocked, that is, the practicability of this type of anti-theft well cover is not strong.

Description

technical field [0001] The invention relates to a road safety device, in particular to a well cover. Background technique [0002] At present, in urban construction, various pipelines of public facilities such as electricity, communication, water supply and drainage, gas supply and fire protection are all installed underground. In order to meet the needs of installation, maintenance and cleaning, a wellhead will be set up at intervals . In real life, a well cover is generally installed on the well head, and the well cover generally includes a base and a cover plate arranged on the base. Because the cover is only laid on the base, criminals often steal the cover, which can lead to serious consequences. In order to prevent the cover plate from being stolen, a class of anti-theft manhole cover has appeared on the market, and it usually adds an anti-theft lock between the cover plate and the base. Its structure is complex and its production cost is high. Simultaneously, part...
