Abstract

The utility discloses an anti-theft manhole cover and comprises a manhole cover body provided with built-in lock which can lock the manhole cover body on framework. The anti-theft manhole cover has the advantages that the anti-theft manhole cover is simple to make, the manhole cover is anti-theft, the manufacturing cost is low, and the anti-theft manhole cover is conducive to promoting the scientificness and integration of municipal engineering management.

Description

A kind of anti-stealing manhole cover

Technical field

The utility model relates to municipal engineering manhole cover field, relates in particular to a kind of anti-stealing manhole cover.

Background technology

In urban construction, be unable to do without the sewerage construction, the well lid that this just need to arrange a lot of construction wells and be used for capping construction well.Present well lid mostly is cast-iron structure, because having to recycle, cast iron is worth, some undesirables stole well lid under the ordering about of interests, and existing well lid majority does not possess anti-theft feature, often cause losing of well lid, not only cause waste, return the pedestrian and vehicle causes security threat.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and effectively antitheft well lid of a kind of prodigiosin is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of anti-stealing manhole cover, comprise framework and well lid main body, and described well lid main body is provided with and can makes the built-in locking device of well lid body lock on framework.

Further, described built-in locking device comprises rotatable built-in latch fitting, the lockaid gun that cooperates with built-in latch fitting, and the bottom of built-in latch fitting is provided with L shaped card article; Described framework be provided with laterally projecting and with the bayonet socket of L shaped card article lap fit, bayonet socket is positioned at the crossbeam top of L shaped card article.After well lid placed, will place the bayonet socket below that the L shaped card article of well lid lower end is fixed in the framework homonymy to pin by the lockaid gun 90-degree rotation, and reach antitheft purpose, lockaid gun counter-rotating 90 degree get final product open manhole cover.

Further, two jiaos of tops of described framework one end are welded with the triangle steel plate and form bell and spigot; Described well lid main body one end is provided with the triangle insert head of corresponding bell and spigot.

Further, the wide and long specification of described well lid main body is 780mm * 780mm, 780mm * 1080mm, 1080mm * 1080mm.

The beneficial effects of the utility model are: this well lid must could be opened with special-purpose lockaid gun by forming with the framework of bell and spigot and built-in lock bayonet socket with the well lid of built-in latch fitting, has effectively solved the problem that well lid is lost.The utility model is made simple, and cost is lower, is conducive to promote scientific, the integrated system of municipal engineering management, is a kind of very promising municipal manhole cover.
