Description
[technical field]
The utility model relates to a kind of well lid, especially relates to a kind of antitheft cable well well lid.
[background technology]
Plumbing in current city, communication, cable television, traffic signals, electric power, combustion gas, the well lid loss problems such as heating power are very serious, in order to take precautions against the loss problem of well lid, market there is the cement or the glass fibre reinforced plastic manhole covers that there is no sales value, but a lot of well lid is on road in city, especially after load-carrying vehicle passes through, be easy to damage by pressure, so the well lid on road is substantially all that old-fashioned casting iron well lid is once stolen, just trap can be caused, lead to traffic accident and personal injury and power cable be cut and destroy, so the loss of well lid and damage, directly threaten the safety of life and property of the masses, cause unnecessary manpower and materials and economic loss, social concern caused by well lid problem, become a hidden danger of urban safety.
[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of antitheft cable well well lid, utilize the annular internal projection bar clamping of the strip projected parts on well lid annular protrusion and walling crib, the key special by the utility model also can be opened by two people, has effectively taken precautions against the loss problem of well cover of cable well.
For achieving the above object, the utility model adopts following technical scheme:
A kind of antitheft cable well well lid, be made up of well lid, walling crib, described well lid comprises upper cover plate, annular protrusion and strip projected parts, the upper side of upper cover plate is interval with two holes, the bottom surfaces of described upper cover plate is provided with annular protrusion near outer rim place, is respectively equipped with strip projected parts in both sides, the lower end outer rim of annular protrusion; The annular plate internal orifice bottom of walling crib is provided with ring-type riser, and in described ring-type riser, basifacial is provided with annular internal projection bar, and described annular internal projection bar is provided with two corresponding gap; The strip projected parts of annular protrusion is through after the gap of annular internal projection bar, and described strip projected parts upper side is in the bottom surfaces of annular internal projection bar, and the bottom of upper cover plate outer rim is made on the annular internal projection bar of walling crib.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Antitheft cable well well lid described in the utility model, be mainly for current theft well lid and implement larceny the single late into the night, be provided with the special key that two people coordinate open manhole cover, by the annular internal projection bar clamping of the strip projected parts on well lid annular protrusion and walling crib, the handlebar holding special key respectively by two people when opening well cover of cable well operation can be opened, and has effectively taken precautions against the loss problem of well cover of cable well.
