Description

A kind of antitheft anti-kill-job lid

The utility model belongs to road surface manhole shaft facility, is specifically related to a kind of antitheft anti-kill-job lid.

Along with developing rapidly of town and country construction, be provided with a large amount of manhole shafts with buried pipe gauzes such as the supporting plumbing of road, surface structures, coal gas, hot-water heating, communications.Because well lid does not have anti-theft device, and open hole place intensity is lower, and lose and the pressure break of well lid are damaged phenomenon and taken place again and again, cause the national wealth loss, traffic accident of Yin Faing and casualties have what is heard also the time therefrom, and this has become the social concern that concerns public's safety.

The purpose of this utility model is that a kind of modified well lid with antitheft, anti-pressure break 26S Proteasome Structure and Function is provided at above-mentioned situation.

Technical solution of the present utility model is:

Antitheft anti-kill-job lid is made up of well lid and walling crib two parts.Anti-theft safety lock is equipped with in the well lid bottom, and the keyhole of safety lock is positioned on the well lid, and dead bolt is positioned under the walling crib annular seating.Be provided with dustproof sheet above keyhole, dustproof sheet is sleeved on anti-the pressure on the screw rod, and fixes by upper and lower nut and well lid.At ordinary times, dustproof sheet covers the keyhole top and shields, and in the time of need opening well lid, nut is unclamped, and the dustproof sheet turn away, exposes keyhole, opens safety lock, well lid can be taken away.

For increasing the fastness of walling crib, to avoid prizing easily, the utility model suitably increases the walling crib height, makes to bury the intensification of people's under ground portion, and in both sides, walling crib bottom antitheft fixed head is set.

For increasing the intensity of well lid, do not establish open hole on the well lid, can will prevent that pressing screw rod to block mentions well lid by instrument during unlatching.During installation, the anti-outstanding ground of screw rod of pressing, its head is painted with yellow, can play a tangible sign effect.The large-tonnage truck sees that this sign should note not allowing tire be pressed onto on the well lid, damages to prevent the well lid pressure break.

The utility model manufacturing process is simple, and is easy to install, and its antitheft anti-pressure effect is obvious.Can prevent effectively that well lid from losing the phenomenon of damaging with pressure break and taking place, be applicable to the well lid of various manhole shafts.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Accompanying drawing is antitheft anti-kill-job lid structural representation.

Wherein: 1, walling crib 2, annular seating 3, anti-screw rod 4, dustproof sheet 5, safety lock 6, well lid 7, keyhole 8, nut 9, dead bolt 10, the antitheft fixed head of pressing

As shown in the figure, well lid 6 is arranged on the annular seating 2 of walling crib 1, and anti-theft safety lock 5 is installed in well lid 6 bottoms, and its keyhole 7 is positioned on the well lid, and dead bolt 9 is positioned at the below of annular seating 2.The anti-screw rod 3 of pressing is installed on the well lid of safety lock 5 one sides, and the dustproof sheet 4 that is sleeved on the anti-pressure screw rod covers on the keyhole 7, and dustproof sheet tightens together by upper and lower nut on the screw rod 38 and well lid.Antitheft fixed head 10 is positioned at walling crib 1 lower end, and is and is symmetrically distributed in the walling crib both sides.

The utility model is through preliminary on probation, respond well.
