Description

The gate-type anti-stealing manhole cover

A kind of gate-type anti-stealing manhole cover belongs to the overburden technical field of manhole shaft or similar item, is mainly used in to cover sink hole, telecommunication manhole, water supply and draining well or the ditch is suitable for reading etc. down.

Various wells such as sink hole, telecommunication manhole etc., especially well head are built on the road or the road is other in prior art, and the ditch is suitable for reading down that a circle or plinth are often arranged, and lay a circle or square cover plate or grate on the stopping table within it.Its cover plate of this well lid or grate or grate plate and its base are discrete separately, easily stolen by the lawless person, be positioned at misplacing automatically easily again of place, slope and expose a part of well head or the exit or entrance of a clitch, so, no matter be that cover plate or grate plate are stolen, still automatically dislocation, all existence can make on the road pedestrian or wheel fall in the well accidentally, the lighter hinders, the danger that weight person dies.

It is a kind of simple in structure that the purpose of this utility model is to provide, and it is convenient to install and open, and the gate-type anti-stealing manhole cover of pedestrian and vehicle safety is guaranteed in the antitheft anti-dislocation of energy.

According to manhole shaft well head characteristics with to obducent requirement, at the subject matter that exists in the prior art, basic design of the present utility model is: with known circle or square lid one dimidiation, half is the plate of uncapping earlier, second half plate of uncapping after being, respectively there are an inserting bolt type linkage and base inner wall hinged, and the special switch mechanism that a usefulness special spanner just can open or close established in the nearly center of joint close, thereby realize purpose of design at both.

Of the present utility modelly be characterised in that described gate-type anti-stealing manhole cover, by the cover plate that has two unlatching hook jacks and be fixed on well head for lay cover plate with and the base ring of band female end platform constitute, its prominent features be above-mentioned cover plate be gate-type and be divided into after the uncap plate and the plate of uncapping earlier, they are hinged by inserting bolt type linkage and above-mentioned base ring respectively, so that cover plate and base ring were connected with each other, make cover plate raise the enough apertures of Shi Nengyou again, simultaneously above-mentioned two cover plates and base ring inwall separately lower edge be respectively equipped with spacing block set and corresponding (on the cover plate to the base ring inwall or antithesis) limited impression, the dislocation of vacillating now to the left, now to the right when being vibrated with preventing well cover, two above-mentioned cover plates to joint close nearly center uncap earlier in the axis hole on the plate and below also be provided with by switch shaft, rotating cam and carriage are formed has only the special switch mechanism that just can open or close with special supporting with it spanner.

Above-mentioned inserting bolt type linkage is by the plug collar that is cast as one with the inner face (towards the one side of well) of above-mentioned two cover plates respectively, T font plug, the hinge seat and the hinge axis of the band installing hole that is cast as one with above-mentioned base ring female end platform inwall constitute, after above-mentioned T font plug inserts in the above-mentioned collar, its other end (being a studless end) is hinged by above-mentioned hinge axis and above-mentioned hinge seat, this hinge axis one end carries die, the other end pass the seat installing hole after rivet hot, so that can make plug, axle can be removed easily around this upset.

Switch shaft in the above-mentioned special switch mechanism has and has only abnormal shape (as the triangle) spindle nose that could twist with supporting with it special spanner, this is contained in the installing hole on the above-mentioned plate of uncapping earlier, its other end (promptly being exposed at the outer end of cover plate inner face) is fixedlyed connected by pin with above-mentioned rotating cam, so that this cam rotates with axle, above-mentioned carriage is to be positioned at below the above-mentioned rotating cam to be cast as one with above-mentioned two cover plates inner face and at the flat shell that tape edge is respectively had an opening.

Above-mentioned two cover plates can unite two into one and the available iron grate replaces cover plate, at this moment, above-mentioned linkage only need a cover and and special switch mechanism be installed in the two ends of cover plate or grate axis of symmetry respectively.

The utility model has the advantages that: simple in structure, make installation and open all very convenient, technological requirement is not high, and size shape is not limit, and can justify, opening needs to use special spanner, desiring to make cover plate to separate with base ring must increase the difficulty of theft one's share of expenses for a joint undertaking crime with operating under the cutting tool in well, theftproof performance is reliable, cover plate or grate are difficult for stolen or dislocation, have guaranteed pedestrian and vehicle safety.
