Description
Technical field
The utility model relates to a kind of inspection shaft facility, relates in particular to a kind of cladding system of antitheft, anti-detachment well head.
Background technology
Initial as you know road inspection shaft lid all is a cast iron, often stolen when waste product and sell for money by the lawless person, cause inspection shaft to become trap, road pedestrian, vehicle are all existed certain potential safety hazard, in order to stop the stolen phenomenon of cast iron inspection shaft lid, through technological innovation, adopt composite material to make the inspection shaft lid, though nobody has stolen.Meaning inspection shaft lid itself has been a safety from certain, because the made inspection shaft lid of composite material follows the inspection shaft mouth that is covered not match mostly, when truck rolls from above in the past, well lid will perk, sometimes the inspection shaft lid also can occur and from inspection shaft, " fly " to go out, " trap " of uncovered occur.Can a kind of potential safety hazard be arranged to pedestrian and vehicle equally, all multimedias are often reported the thing that pedestrian or vehicle " have been stung " by the uncovered inspection shaft, and the somebody causes slight wound, and the somebody causes serious fracture.This design that inspection shaft lid has been described is zero defect not.
Summary of the invention
The purpose of this utility model is: develop a kind of inspection shaft with lock lid, prevent and stop artificial stolen and automobile rolled perk even the disengaging well head that flies out from well lid, ensure the safety of pedestrian and vehicle.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals, a kind of inspection shaft with lock lid.It is characterized in that: a lid is arranged, be connected with a base on the lid, a disk is arranged on the base, disk is connecting two lid bolts.
The center of described lid is provided with the Gaizhonggai of a circle, has axis of rotation to be connected between Gaizhonggai and the lid, can open and close.
The center of described base is provided with the columniform axis of rotation of a protrusion, and four angles of base respectively are provided with an eye.
The center of described disk is provided with a circular eye, and the both sides of eye symmetry are provided with recess, and the edge of disk is provided with the sawtooth of systematicness.
One end of described lid bolt is provided with and the corresponding sawtooth of disk border sawtooth, is provided with two bolt cards in the one side relative with sawtooth.
The beneficial effects of the utility model are: prevent and stop artificial stolen and vehicle and rolled and the perk even the disengaging well head that flies out from well lid, ensure the safety of pedestrian and vehicle.
Description of drawings
Accompanying drawing 1 is a structure schematic diagram of the present utility model;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
As shown in Figure 1 and Figure 2, the serrate disk 4 in edge is enclosed within on the axis of rotation that protrudes at base 3 centers earlier, then the end that two lid bolts 5 are not had a sawtooth in the opposite direction, the sawtooth at serrated portion alignment disk 4 edges is fixed on the back side of lid 1 again with key screw base 3.Distance between base 3 and the lid 1 is greater than the thickness of disk 4, and being convenient to disk can rotate, and inspection shaft lid with lock has so just installed, and every lid all is furnished with the concavo-convex key of unified rotation.Because the lid bolt pre-sets length, on the every lid bolt bolt card is arranged all, can not be shifted because of rotating excessively.Before covering inspection shaft, open the concavo-convex key of Gaizhonggai 2 usefulness earlier lid bolt 5 is rotated in the edge of lid 1, cover again on inspection shaft, lid bolt 5 is rotated to outside the edge of lid 1, just in time block the inspection shaft mouth, middle cover closes the lid.Lid just is fixed on the inspection shaft mouth like this, does not have the concavo-convex key of this rotation well lid of not opening, and automobile rolled from above more not can the perk and the disengaging well head that flies out, and this thus inspection shaft lid was both antitheft anti-to be rolled, and has ensured the safety of the person with vehicle again.
