A stainless steel manhole cover with rebound self-locking structure and its locking method

Abstract

The invention discloses a stainless steel manhole cover with a springback self-locking structure and a locking method thereof, which belongs to the technical field of stainless steel manhole covers, and comprises a well ring seat on which a well cover is arranged, and the well cover is self-locking through springback. The lock mechanism is fixed on the well ring seat, and a thimble unlocking mechanism is embedded in the well cover, and the well cover is unlocked from the well ring seat through the thimble unlocking mechanism. The stainless steel well cover with rebound self-locking structure and its locking method of the present invention, the well cover presses down the wedge-shaped self-locking block, the telescopic spring and the telescopic guide post are compressed and contracted, so that the wedge-shaped self-locking block is in the accommodation groove under the action of the guide ball After the well cover is installed on the well ring seat, the wedge-shaped self-locking block rebounds into the limit groove, and the well cover is locked on the well ring seat, so that the well cover is installed flat and stable, and the well cover is not easy to lift, which fully protects vehicles or pedestrians It is safe when driving, and the well cover can be quickly disassembled from the well ring seat, which is easy to disassemble and maintain and convenient to use.

Description

technical field [0001] The invention relates to the technical field of stainless steel well covers, in particular to a stainless steel well cover with a rebound self-locking structure and a locking method thereof. Background technique [0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They can be used for green belts, sidewalks, motorways, docks, alleys, etc. . [0003] Manhole covers are generally divided into round and square according to their shapes; in terms of road administration in urban areas, round manhole covers are generally used, because round manhole covers are not easy to tilt and can better protect the safety of pedestrians and vehicles. They are used in rural areas and cable wells. Generally, it is square, which can better prevent the entry of rai...

AI Technical Summary

Problems solved by technology

[0004] When the existing manhole covers cover the road, because the manhole ring seat is not flat when it is made, and the manhole cover is not locked on the manhole ring seat, when vehicles or pedestrians drive from the manhole cover, the manhole cover is easy to tilt up, which is dangerous for vehicles or pedestrians. Pedestrian driving brings potential safety hazards, and although some well covers can be locked on the well ring seat, the removal and maintenance of the manhole cover is cumbersome and extremely inconvenient to use
