Pressing type resilient rotary anti-theft well lid and assembling method thereof

Abstract

The invention discloses a pressing type resilient rotary anti-theft well lid and an assembling method thereof. A fan-shaped matching block plays a limiting role, a triangular block is used for improving the overall strength of a frame foundation, limiting grooves which are symmetrically distributed are formed in the inner side of a stress cylinder, the limiting grooves make contact with a guidingand limiting assembly and are used for limiting the guiding and limiting assembly, a sealing cover and an inner supporting assembly are arranged as a whole and are located over the frame foundation, the guiding and limiting assembly can play a limiting role in the normal state, the surface of the sealing cover and the surface of the frame foundation are flat; when extreme conditions such as rainstorm occur, the sealing cover is pressed downwards and rotated, the sealing cover drives a pressing plate and the guiding and limiting assembly to rotate together; when the guiding and limiting assembly leaves the limiting groove, the guiding and limiting assembly is not limited any more, the sealing cover can be jacked up, rainwater can smoothly flow into the anti-theft well lid in rainstorm weather, meanwhile, the anti-theft well lid is difficult to maliciously pull up, and safety is good.

Description

technical field [0001] The invention relates to an anti-theft well cover, in particular to a push-type springback rotating anti-theft well cover and an assembly method thereof. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. Manhole covers can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers according to their materials. Manhole covers are generally round. It can be used in green belts, sidewalks, motorways, docks, alleys, etc. The manhole cover is generally a single layer, but for better protection, it is necessary to use composite materials to make the manhole cover. [0003] Manhole covers have been laid on the road on a large scale, but there will be some thieves who steal the manhole covers and sell them off. So anti-theft manhole cover has occurred, but anti-theft manhole cover is expensive, and practicality is not...

[0003] Manhole covers have been laid on the road on a large scale, but there will be some thieves who will steal the manhole covers and sell them off

Therefore, anti-theft manhole covers have appeared, but the anti-theft manhole covers are expensive and not practical, so there is an urgent need for an anti-theft manhole cover that ensures the drainage effect and has a relatively simple structure.
