Description
[technical field]
The utility model relates to a kind of manhole cover with lock, belongs to public utility corollary equipment field, is mainly used in the sewage disposal device being arranged in greenbelt.
[background technology]
Economic society is in development; all need great lot of water resources every day; after life and activity in production; these water become sewage; these sewage need to just can be discharged in natural water after sewage disposal device is processed; along with the attention of country to environmental protection and drop into increasingly, the demand of corresponding sewage disposal device also can get more and more.But being applied at present the maintenance well lid of these sewage disposal devices, also not forming standard according to its instructions for use, is mostly directly to utilize the existing maintenance well lid in market.But current existing maintenance well lid is applied in some problems of this field existence in various degree and defect.
Current traditional manhole cover with lock is all generally cast iron quality, and the object of configuration lock mainly contains that antitheft, anti-cover plate is beated, safety protection function, is all generally the heavy-load type manhole cover for crossing bus or train route face.The main problem of this type of manhole cover is that Heavy Weight, cost are high, complicated operation.
Current macromolecule recombination materials inspection well lid again, quality is light, cost is low, but because not having recoverable, its material is worth, generally be applied to the inspection shaft in greenbelt, well lid itself does not need to consider anti-theft feature, is therefore generally all unworthy of lock, causes its security performance to have defect, well lid is easy to just can free-handly open, and easily crashes into accident.
Because above-mentioned defect, actively research and innovation in addition, is avoiding after above-mentioned defect, proposes a kind of manhole cover with lock of new structure, makes it have more the value in industry.
[utility model content]
The purpose of this utility model is: for defect and the deficiency of prior art, provide a kind of manhole cover with lock, not only rational in infrastructure, cost is low, and lightweight, easy to operate, safe.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of manhole cover with lock described in the utility model, comprise manhole seat, structure well head and manhole cover, manhole seat is installed on structure well head top, manhole seat is connected and is fixed together by screw and nut with building between thing well head, manhole seat top is provided with manhole cover, locks to be connected to be fixed together between manhole cover and manhole seat by manhole.
In the utility model: described manhole cover center is provided with tooling hole, the center, the back side of manhole cover is provided with stopper slot, and manhole cover edge is provided with well lock installing hole, indicates at the other switch that is provided with of well lock installing hole.
In the utility model: described manhole lock is made up of dead bolt, movable bayonet and tapered end, the end of described dead bolt is with constant slope, tapered end is made up of dead bolt direction arrow, lock core and locked groove, and wherein the instruction of dead bolt direction arrow and switch is in conjunction with judging that manhole locks current locking or releasing orientation.
Adopt after said structure, the utility model beneficial effect is:
(1), a kind of manhole cover with lock of the utility model in the time of the locking of manhole lock, not adopting special tool is to open well lid, can prevent the child lid that drives a well, safe;
(2), critical piece of the present utility model all adopt nonmetals mold produce, lightweight, cost is low, rational in infrastructure.
