A key hole which is matched with a special key is arranged on the cover plate. The utility model has the advantage of simple structure, and can be widely used in the underground engineering, such as water supply and water drainage in the city construction, a communication cable, a gas pipeline, a heat distribution pipeline, etc. Convenience is provided for the overhauling, and the antitheft function is provided.
Description
The utility model relates to underground installation field in the urban construction, relates in particular to a kind of anti-stealing manhole cover.
Urban construction at present all is provided with well head and well lid for maintenance repair is convenient in engineering constructions such as the underground cable of plumbing, communication, power supply, thermoelectricity, piped gas.But because well lid does not have anti-theft device, well lid is lost phenomenon and is occurred repeatedly, this walking along the street safety to urban construction maintenance and people is all brought sizable hidden danger, for addressing this problem, the well lid that the well lid that people's inorganic material on probation is made comes the alternative metals material to make is though this technical scheme has solved the problem of losing of well lid, but because inorganic material intensity difference, cause this class well lid breakage many, and heavy because this class well lid volume is big, when maintenance, move trouble.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of Strength Safety that can guarantee well lid is provided, and has anti-theft feature again, and switch anti-stealing manhole cover easily.
The purpose of this utility model is achieved in that a kind of anti-stealing manhole cover, mainly is made up of well seat, cover plate etc., and its special character is that this well lid comprises: an end hinges of cover plate and well seat; The other end back of cover plate is fixed with lockset and dead bolt is stuck in the well seat groove; Cover plate is provided with the hole and is furnished with private key.
Compared with the prior art the utility model has following good effect: the first is because the utility model is taked to carry out hinge at an end of cover plate and well seat, and the other end is provided with lockset and private key, thereby guaranteed that cover plate should not lose, and has anti-theft feature; It two is because cover plate well seat all adopts cast iron materials casting to form, and the cover plate back side is provided with reinforcing rib, thereby has guaranteed the intensity of well lid, and is unsuitable damaged; It three is provided with boss owing to be provided with the well seat inner edge place at pin hinge and well seat and penny washer hinge place in cover plate and well seat junction, thereby has guaranteed need not move after cover plate is opened, and maintenance work is made things convenient for, and the location of assurance when closing.
Concrete structure of the present utility model is provided by following drawings and Examples.
