Description
Technical field
The utility model belongs to well lid, relates in particular to a kind of municipal administration that is applied to, water supply and draining, power supply, heat supply, coal gas, the Safety well cover of underground pipeline facility well heads such as telecommunications.
Background technology
At present, the wellhead assembly that various underground pipeline facilities are provided with at the well head place, well lid and the cage two large divisions by the band open hole constitutes usually, because well lid is only withheld on cage, be easy to be stolen, cause any property loss, also can cause a series of accidents, dangerous.For this reason, occurred well lid and cage be hinged or stung slottingly, and in position located to establish the product of built-in lock.Disclosed a kind of anti-stealing manhole cover device among the example CN2285323Y, its well lid is connected by the overhanging link slot hinge of overhanging junction plate and cage, built-in lock in the well lid appropriate position is made of rotating shaft and plug, needs private key to open, and has certain antitheft effect.But its weak point is: use inconvenient, security reliability is poor, be inclined upwardly when well lid is opened, with the angled setting in ground, the well lid of holding up produces cage and prizes power, causes whole device loosening, the well lid of erectting also is unfavorable for the operation of well head, and unstable; Blind hole of unblanking and concave inward structure all are located at the well lid surface, block in case filled up by earth, dirt and so on, just can't use, though protective cover can be set, the lid on outstanding ground is easily pulverized or loses; The concave inward structure of capping, easy progradation water though antirust sleeve is arranged, can not prevent the corrosion of irony member or freeze mutually that the rotating shaft of lock can't be rotated, and influence is used.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of shaft mouth operation that makes things convenient for is provided, and reliable operation, is not made of salt or accumulated snow, Safety well cover that theftproof performance is good.
The utility model for achieving the above object, by the following technical solutions: a kind of Safety well cover, comprise the well lid of being with open hole and have the rim of the mouth and the cage on holder edge, it is characterized in that: the corresponding open hole of described well lid is provided with bolt hole, be provided with built-in lock between described well lid and cage, dowel, described built-in lock is by manger shape lock body, lock core, reed constitutes, the rectangle lock core is housed in lock body, described lock core one end is provided with groove or projection, be provided with elongate slots along playing long axis direction in the middle of the lock core, in bottom, lock body outside the rectangle reed is housed, corresponding lock core groove of described reed one end or projection are provided with projection or the groove that plugs together, described built-in lock is by being bolted on the well lid, and described dowel is by being bolted on the well lid.
The nuts surface of described fixedly built-in lock and dowel is provided with unlike signal.
Two different bolts of fastening bolt cap sign are set up in dowel, built-in lock installation site relatively on the described well lid.
The holder that described well lid through hole length is well lid thickness and cage is along the thickness sum.
The described well lid open hole below water boss of setting up defences.
The beneficial effects of the utility model: easy to use, flexible, both can be antitheft, work safety, reliable again.The same with well lid commonly used when well lid is opened, the mode of unblanking is hidden, unique, is not subjected to the influence of ambient conditions substantially, and also can use normally winter.On screw, can do sign, as: marks such as electricity, water, letter, dirt, as the sign of applying unit.Bolt position can arbitrarily be allocated, and makes the thief be difficult for finding.
