A fall-proof manhole cover for municipal roads

Abstract

The invention relates to the field of municipal facilities, and discloses an anti-falling manhole cover for municipal roads, comprising a cover body and a base connected with the ground, the cover body is rotatably connected with the upper side wall of the base, and the lower part of the base is rotatably connected. The side wall is rotatably connected with a connecting frame through a torque shaft, the inner wall of the connecting frame is fixedly connected with a net pocket, the outer wall of the base is slidably inserted with an abutting rod, and the outer wall of the abutting column and the outer wall of the base are fixedly connected There is a telescopic spring sleeved on the outer wall of the abutting rod, a magnet block 1 is fixedly connected to the end of the abutting rod, and a connecting plate is fixedly connected to the outer wall of the base. The present invention has the following advantages and effects: the present invention limits the cover body by setting the abutting rod to prevent the cover body from being stolen, and at the same time, after the cover body is stolen, the abutting rod continues to move inward to limit the position of the net pocket, ensuring that the net pocket cannot be Rotating downward, it realizes the protection of pedestrians who accidentally fall into the sewer, and ensures personal safety.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to an anti-falling manhole cover for municipal roads. Background technique [0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section, from the pipeline to the ground. It is called a manhole, and the mouth of the manhole is usually flush with the ground, so a cover is needed to cover the lid of the manhole, which is called a manhole cover. [0003] Because the manhole cover contains metal materials, criminals will steal the manhole cover for profit, resulting in holes on the road. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an anti-falling manhole cover for municipal roads, which has the effect of conven...
