Anti-falling well lid structure

Abstract

The invention discloses an anti-falling well lid structure. The well lid structure comprises a well lid seat, an annular lid plate, a well lid body and a locking mechanism, the well lid seat is provided with an L-shaped step, the lid plate is fixedly arranged on the step of the well lid seat, elastic assemblies are arranged in the well lid seat at intervals, penetrating holes are formed in the positions, corresponding to the elastic assemblies, of the lid plate, the well lid body is placed on the well lid seat and located on the lid plate, the locking mechanism is installed on the bottom faceof the well lid body, and the locking mechanism is used for locking or opening the well lid body. According to the invention, the locking mechanism is arranged to lock and open the well lid body, so that the well lid body is effectively prevented from being stolen or loosened, meanwhile, the well lid body can be prevented from being opened by water flow in rainstorm weather, the elastic assemblieson the well lid seat can automatically bounce upwards when the well lid body is replaced or opened by water flow, a warning effect is achieved, passers-by can be effectively reminded, and risks thatthe passers-by fall into a well carelessly are reduced.

Description

technical field [0001] The invention relates to an anti-dropping manhole cover structure. Background technique [0002] Most of the manhole covers in real life are directly placed on the manhole cover base, and there are no other fixing measures. At the same time, after the manhole cover is replaced, the manhole cover is stolen, and the manhole cover is washed away by the water flow, there is no corresponding early warning measure to remind passers-by, resulting in It often happens that passersby fall into the well. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an anti-falling manhole cover structure. [0004] For achieving the above object, the concrete scheme of the present invention is as follows: [0005] An anti-falling manhole cover structure includes a manhole cover seat, an annular cover plate, a manhole cover and a locking mechanism, the manhole cover seat is provided with an L...
