Abstract
Disclosed is an anti-theft manhole cover. The anti-theft manhole cover comprises a manhole cover body. A manhole cover is arranged on the manhole cover body. A square key hole is formed in the center of the reverse side of the manhole cover, and a rubber plug is arranged in the square key hole. Reinforcing ribs are arranged on the periphery of the square key hole, and track semicircle portions are arranged on the periphery of the reinforcing ribs. Telescopic rods are installed outside the track semicircle portions. A pulley is installed at one end of each telescopic rod, a spring is installed on one side of each telescopic rod, a manhole base is installed on the same sides of the telescopic rods, and the manhole cover is clamped into the manhole base through one end of each telescopic rod.

Description
Technical field
The present invention relates to technical field of burglary prevention, specially a kind of theft-proof manhole cover.
Background technology
At present, needed in urban and suburban roads and all kinds of pumping equipments many in provided underground such as water, electricity, communication, draining etc.
Pipeline is planted, the well head for draining and observation and maintenance subterranean pipe line is also set up, the most of of covering well head use cast iron
The well lid of material manufacture, and be to cover on well seat well lid, because the well lid that traditional cast iron materials are made has necessarily
Recovery value, and currently used for well lid anti-theft measure very imperfection, do not possess anti-theft feature, so well lid easily be stolen,
And once lose, not only the facility protected can be caused to damage and bring economic loss to national enterprise, and be possible to lead
The generation of cause accident, has seriously threatened the safety of the pedestrian and vehicle walked on road, and serious can even pacify to the person
Unpredictalbe injury is caused entirely, and the social concern caused by the safety problem of well lid has become in people's life
Major hidden danger；Meanwhile, well lid easily activity on well seat, with regard to bob, sends great noise, band once by external force
Carry out very big noise pollution, the life for giving people brings very big inconvenience；Furthermore traditional well lid shows urban culture at some
Engineering in, traditional well lid seems and unsightly misfitted very much with whole engineering very much, reduce city culture image, not
The need for social development being met.
Many lawless persons steal the well cover for sewer used on highway at present, and many well lids all use water-setting coagulation instead at present
Soil is poured, but the well lid hardness that cement concrete is poured is not enough, the vehicle crushing that conventional well lid is all also travelled when long.
The content of the invention
A kind of well seat it is an object of the invention to provide expansion link of the reverse side in well lid and well lid surrounding constitutes one
Individual anti-theft device, under normal circumstances, the tail end of expansion link is stuck in lateral aperture, is so in a kind of keyed in usually well lid
State prevents from being stolen, when needing to open well lid inspection, by special key, by the square key in the middle of well lid
Hole, it is possible to a kind of theft-proof manhole cover for opening well lid, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of theft-proof manhole cover, including manhole cover body,
The manhole cover body is provided with well lid, and the centre of the well lid is provided with square keyhole, and the inside of square keyhole is provided with rubber
Plug, the outer periphery of the square keyhole is provided with retainer ring, and retainer ring is provided with retaining rail, and retaining rail is welded on the anti-of well lid
Face, the square keyhole is formed around reinforcement, and reinforcement is integrally formed with manhole cover body, set on the outside of the reinforcement
The side for having track semicircle, the track semicircle is provided with expansion link.
Preferably, one end of the expansion link is provided with pulley, and pulley is structure as a whole with expansion link, the side of the expansion link
Face is provided with spring support, and the spring support is welded on expansion link, and spring is provided between the spring support, the spring
One end is fixed on well lid, and the other end of spring is connected with expansion link.
Preferably, the side of the well lid is provided with well seat, and the inner side of the well seat is provided with lateral aperture, the lateral aperture
With expansion link in same level highly.
Preferably, the length of side of the square keyhole is 20mm.
Preferably, the well lid is made with well seat of cast iron, and the well seat is provided with four lateral apertures, the depth of lateral aperture
It is 16mm to spend.
Preferably, the retainer ring is circle.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）Cylinder iron material is made well lid with well seat, and cast iron has hardness very high, while also having good antirust；
（2）An anti-theft device is constituted with the well seat of well lid surrounding in the expansion link of reverse side of well lid, under normal circumstances, is stretched
The tail end of contracting bar is stuck in lateral aperture, so prevents from being stolen in a kind of state of keyed in usually well lid, is needing to open well
When lid is checked, by special key, by the square keyhole in the middle of well lid, it is possible to which well lid is opened；
（3）Rubber stopper is housed on the square keyhole in the middle of well lid, prevents square keyhole to be chronically exposed to road surface easily quilt
Silt is blocked, and rubber stopper is not limited by profile, with good elasticity, can be firmly stuck in square keyhole, is not allowed
It is easy to fall off.
