Abstract
The utility model discloses an anti-theft and noise defense well cover, comprising a cover seat fixed on the ground and an openable face covering. A boss is arranged on the inner wall of the cover seat, with a positive stop screw bolt that can be up-and-down extracted inserted through the boss. The positive stop screw bolt hinges the cover seat and the face covering together. The anti-theft and noise defense well cover of the utility model has the advantages of anti-theft, noise defense, anti- bounce, easy open and close, convenient installment and the like, resolving the questions of loss of municipal pipe line resulted from well cover being pilfered, which can further effectively avoiding fortuitous casualty caused by well cover being pilfered, with great social benefit and economic benefit.
Description
Technical field
The utility model relates to a kind of manhole cover, particularly a kind ofly is used to supply water, the manhole cover of municipal pipeline facility such as combustion gas, draining, power supply, telecommunications.
Background technology
Because historical reasons, the existing well lid that is installed on the road is the casting pig well lid basically.The casting pig well lid is broken into return scrap into pieces easily because its fragility is big, usually levered up to steal by the thief and sell the waste and old material recycle bin, so the casting pig well lid is often stolen, and theftproof performance is poor, and the casualty accident that causes causes extremely bad influence to society; Because the lid of casting iron well lid is that metallic hard contacts with seat, vehicle also often is subjected to resident's complaint through the noise of out-of-date generation again.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of energy to solve antitheft problem, and is easy to use long with the life-span, has the well lid of antitheft, anti-spring, noiseproof, easily keying, convenient installation.
The purpose of this utility model is achieved by the following technical solution: antitheft noiseproof well lid, constitute by cage that is fixed in ground and the cover that can open, the inwall of cage is provided with a boss, is interspersed with on the boss to take out the caging bolt of dialling up and down, and caging bolt is hinged with cage and cover.Further, influence evenness of road surface for avoiding bolt head to give prominence to, cover is provided with the counterbore of corresponding interspersed caging bolt head.For effectively antitheft, the caging bolt bottom is screwed with nut, nut and caging bolt solid welding.Also be provided with on the cage inwall and bump button, the bottom surface of cover be provided with can with " U " shape jump ring that bumps button elasticity snapping on the cage.Adopt jump ring, can be closely together lid and cage after covering cover, cover could be pried open with special-purpose drill rod, simultaneously, can prevent the well lid spring, the reduction noise has increased its anti-theft feature to a certain extent.
The utility model is compared with original casting pig well lid, has following advantage:
1, antitheft with caging bolt, anti-theft feature is strong, and convenient the installation after the nut solid welding, do not cut off bolt, and well lid just can not freely be moved.
2, open and close rapidly convenient various repairings: avoided well lid with locking the antitheft inconvenience of bringing.
3, jump ring location could be pried open well lid with special-purpose drill rod, has increased its anti-theft feature to a certain extent, and the well lid spring can effectively abate the noise when preventing simultaneously that vehicle from passing through, and minimizing is to the influence of resident living.

The specific embodiment
Referring to Fig. 1-Fig. 5, the ductile iron well lid of present embodiment is by cage 1, cover 2, caging bolt 3, nut 4, shockproof rubber coil 5 constitutes, cage 1 generally is fixed on the road surface by cement mortar, 2 of covers are mobilizable, special feature is the boss 11 that the inwall of cage 1 is provided with a band through hole, correspondence is provided with counterbore 21 on the cover 2, caging bolt 3 passes counterbore 21, the through hole of boss 11 is hinged with cover 2 and cage 1, the length of caging bolt 3 has surplus, it can be taken out up and down between cover 2 and cage 1 dials, but nut 4 and the bolt solid welding screwed in its underpart, and the external diameter of nut 4 is greater than the internal diameter of boss 11 through holes, like this, caging bolt 3 makes cover and cage be connected into one.When needs are opened cover 2, available drill rod levers up cover 2, cover 2 is increased to more than the ground level, cover 2 just can be done rotating freely of 360 ° of scopes at ground line around caging bolt 3, the well lid mouth is opened, cover 2 is subjected to the constraint of caging bolt 3 related with cage 1 all the time simultaneously, unless cut off bolt, cover 2 can't be moved.In addition, link closely mutually in order to make between cover 2 and the cage 1, on the inwall of cage 1, also be arranged with three and bump button 12, correspondence is provided with three " U " shape jump rings 22 on cover 2 bottom surfaces, when cover 2 and cage 1 closed, the termination elastic deformation of jump ring 22 also was interlockingly connected with bumping button 12, makes the inner elastic tension power that forms radially of well lid, thereby prevent the external force when well lid is crossed by vehicle in the above and bounce the reduction noise.Have an annular groove on cage 1, groove is embedded in shockproof rubber coil 5, make it directly to contact with cover 2, thus the noise that collides and produce between more effective elimination lid and the seat.
Certainly, only enumerated a kind of preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
