Description
Technical field
The utility model relates to a kind of well lid, is specially a kind of anti-stealing manhole cover.
Background technology
At present, well lid, the equal plane of Well grate or chain cable are placed on the well lid skeleton frame, and the operating personnel can arbitrarily raise well lid and keep in repair, installs or every work such as cleaning, but because its manufactured materials is iron, steel, have also stayed the chance of committing theft to the lawless person simultaneously.Because the well lid coverage is too wide, to put in the open, the monitoring difficulty is bigger, causes to lose a lot ofly, not only causes potential safety hazard, has influenced urban environment, and national wealth is suffered a loss.For preventing lawless person's larceny, people have also taked many measures, make well lid as using nonmetals, and its defective is not ideal at aspects such as outward appearance and bearing capacities; Or chain or theftproof lock are set between well lid and manhole cover base, because lockset is a metal material, its defective has been of long duration is subjected to rainwater to attack or be subjected to the influence of moisture laden air, gets rusty easily especially.
Summary of the invention
The utility model is very easily stolen and cause potential safety hazard for pedestrian, vehicle, influence problem such as urban environment and a kind of anti-stealing manhole cover is provided in order to solve existing well lid.
The utility model is to adopt following technical scheme to realize: anti-stealing manhole cover, comprise base, cover plate, the base border is provided with groove, cover plate is made of upper cover body and lower cover, be fixed with the switch column that inside is provided with square lockhole on the lower cover, upper cover body be socketed on the switch column and and lower cover between leave the gap, be provided with two active cards between upper cover body and the lower cover and corresponding to the groove position on the base; The body of turning round that can rotate around it is housed on the switch column, turn round the body two ends be provided with respectively with lower cover on the locking groove stop column of working in coordination; Turning round the body both sides is connected with active card by spring respectively; The switch column lower end has slides mouthful, turns round on the body and has the lifting bayonet socket corresponding to the position of sliding mouthful.Anti-stealing manhole cover described in the utility model must by with switch column in the square lockhole special tool that uses that complements one another just can open or lock.During use, as shown in Figure 1, the unlocking tool of special use is goed deep in the square lockhole in the switch column, to turn round the body lifting by contacting with the lifting bayonet socket with the mouth that slides, make it along the switch column segment distance that moves up, make the locking groove on the stop column disengaging lower cover of turning round on the body, rotating unlocking apparatus then drives afterwards and turns round body and rotate and make the stop column of turning round on the body enter another locking groove on the lower cover, at this moment, turning round body promotes the active card body of both sides and makes its part between upper cover body and lower cover, another part is positioned at the groove of base border, has so just reached the purpose that prevents that well lid is stolen.The utility model is simple in structure, easy to operate, good anti-theft effect.
Nut in order to the enclosed switch post is set on the upper cover body described in the utility model, enters square lockhole in the switch column to avoid rainwater or foul.
Upper cover body described in the utility model and lower cover are by bolt, to guarantee leaving certain clearance between upper cover body and the lower cover.
The beneficial effects of the utility model: rational in infrastructure, be used with the opener of special use, have good anti-theft effect, cost of production is low simultaneously, and good anti-theft effect is manipulated more conveniently, helps popularization on a large scale in.
