Abstract
The utility model relates to a product for municipal engineering, particularly a theftproof manhole cover which comprises a manhole cover and a base, wherein one side of the manhole cover made of steel fiber concrete materials is provided with a plug pin and a special lockset is installed on a cover plate at the other side of the manhole cover. A bottom cover made of cast iron materials is matched with the plug pin. After the manhole cover well covers a manhole and the lockset rotates, a lock bolt of the lockset is positioned at the bottom of the base. The utility model has the functions of high load bearing force, shock and corrosion resistance, theft protection and optional unlocking prevention.
Description
The utility model relates to the municipal engineering goods.
Existing municipal engineering or post and telecommunications engineering have two kinds usually with manhole cover: a kind of is full casting iron well lid, and promptly well lid and base are cast iron entirely, because cast iron has certain recovery value, is easily stolen.The trap that the stolen back of well lid produces has brought the hidden danger on the safety, even has caused the accident.Also having a kind of is steel fibrous concrete well lid, base, though solved the stolen problem of well lid.But in the asphalt surface work progress, because construction machineries such as road roller roll repeatedly, base often has the damage phenomenon, and influence is used and be attractive in appearance, adds lockset is not set, and is easily opened by the people, destroys facility in the well.
The purpose of this utility model is some weak point that exists at above-mentioned existing manhole cover, provides a kind of well lid that solves stolen and prevent the cast iron well seat that the well seat is impaired and the manhole cover of steel fibrous concrete well lid organic assembling.
The technical solution of the utility model is such.This antitheft manhole cover comprises well lid and base two parts.Well lid one side that the steel fibrous concrete material is manufactured has latch, on the cover plate of well lid opposite side special lockset is housed.On the base of manufacturing by cast iron materials the pin-and-hole that matches with latch is arranged.After well lid was built, behind the rotation lockset, the dead bolt of lockset was positioned at the base bottom.There is not special tool to be difficult to well lid is opened after the pinning.
The utility model has increased special lockset owing to adopted steel fibrous concrete well lid and cast iron base combining structure, has strong, shock-resistant, corrosion-resistant, antitheft, the anti-function of arbitrarily opening of bearing capacity.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the utility model comprises base 1, well lid 2.Well lid 2 one sides of being manufactured by the steel fibrous concrete material have latch 3, on the cover plate of well lid 2 opposite sides special lockset 4 are housed.On the base of manufacturing by cast iron materials 1 pin-and-hole that matches with latch 3 is arranged.Base 1 is fixed on to be checked on the well head, during manhole cover, the latch on the well lid 3 is inserted in the pin-and-hole of bases 1, after well lid is built the dead bolt of special lockset is gone to the base bottom and gets final product.Have only the professional can open with special tool.In order to make the well lid load-bearing effective, and rational in infrastructure, the shaft bottom of well lid is a cone-shaped.
