Stainless steel well lid with springback self-locking structure and locking method of stainless steel well lid

Abstract

The invention discloses a stainless steel well lid with a springback self-locking structure and a locking method of the stainless steel well lid, and belongs to the technical field of stainless steel well lids. The stainless steel well lid comprises a well ring seat, a well lid body is arranged on the well ring seat, the well lid body is fixed to the well ring seat through a springback self-locking mechanism, a thimble unlocking mechanism is embedded in the well lid body, and the well lid is unlocked from the well ring seat through the thimble unlocking mechanism. According to the stainless steel well lid with the springback self-locking structure and the locking method of the stainless steel well lid, the well lid downwards presses a wedge-shaped self-locking block, a telescopic spring and a telescopic guide column are pressed to contract so that the wedge-shaped self-locking block can move in an accommodating groove under the action of a guide ball, after the well lid is installed on the well ring seat, the wedge-shaped self-locking block rebounds into a limiting groove, the well lid is locked on the well ring seat, so that the well lid is flatly and stably installed and is not prone to tilting, the safety of vehicles or pedestrians during driving is fully guaranteed, and the well lid can be quickly detached from the well ring seat, is simple to detach and maintain and is 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
