Description

Anti-stealing manhole well lid

Technical field

This utility model relates to the well lid of a kind of inspection shaft, is specifically related to the inspection shaft possessing anti-theft feature Well lid.

Background technology

Inspection shaft quantity in current city is various, and the department related to is the most, including: water utilities, Ten several departments such as real estate management, communication, electric power, tap water, the most only communicate just be subdivided into Netcom, More than 10 units such as Tie Tong, movement, UNICOM, telecommunications.Inspection well cover occurs frequently in driveway Arterial highway on.In city, inspection well cover usually arises a problem that, is not washed away by heavy rain, It is exactly originally not know where gone or stolen；Thus also can cause the deep-well phenomenon that " gulps down people ", Bring the biggest potential safety hazard.City well lid mainly has plating iron, cement and compound material well lid Two kinds, plating iron well lid, because having certain economic value, often becomes some " prey " And be tampered；Cement and compound material the most typically can not work as waste recovery, typically will not be by Steal, but the well lid of cement and composite is due to light weight, is easily washed away by rainwater.In a word, Cover of inspection well is wanted tightly seal inspection shaft, prevents inspection shaft from causing danger to passerby or vehicle, possesses Good theftproof performance, can be connected with inspection shaft securely.Additionally, due to often have vehicle from Process on Cover of inspection well, major part well lid and road surface laminating are tight, when vehicle presses through tire can and Well lid produces collision, and one of well lid therefore noise source becoming city, the common people are deeply by well lid noise Hardship.Therefore, have to fit in well lid and road surface with fitting together perfectly, and combine very Firmly, will not increase along with the time used and cause loosening.

Utility model content

The technical problems to be solved in the utility model is: overcome the deficiency in correlation technique, it is provided that A kind of antitheft Cover of inspection well being firmly combined with ground.

In order to solve above technical problem, technical scheme provided by the utility model is: a kind of Anti-stealing manhole well lid, including circular manhole cover body and the annular corresponding with manhole cover body Well lid frame, described well lid frame includes frame main part and arranges the end of described frame main part The extension that the direction, the center of circle along described well lid frame in portion extends；Described frame main part also wraps Include the through hole being arranged on its surrounding；Described manhole cover body also includes being arranged on its edge and along described Manhole cover body extends radially outwardly anti-theft pin；Described manhole cover body covers at described well lid frame On, the bottom of described manhole cover body is connected to described extension, and described manhole cover body is by described Anti-theft pin inserts the described through hole of described frame main part and matches with described well lid frame.

As further improvement of the utility model:

The quantity of described through hole is 4, and 4 described through holes are uniformly arranged on described frame main body The surrounding in portion；The quantity of described anti-theft pin is 4, is uniformly arranged on described manhole cover body surrounding Edge；When described manhole cover body and described well lid rim fits, 4 described anti-theft pin correspondences are inserted Enter in 4 described through holes of described frame main part.

Described manhole cover body also includes that controls a switch, when controlling switch and opening, and 4 institutes Within stating the edge that anti-theft pin retracts into described manhole cover body, when controlling switch and closing, 4 Anti-theft pin described in root is upheld, corresponding 4 the described through holes inserting described frame main part.

The described switch that controls is arranged on the home position of described manhole cover body.

Described anti-stealing manhole well lid is made up of glass fiber reinforced polypropylene composite material.

Compared with correlation technique, the utility model has the advantage of: described anti-stealing manhole well lid, Including circular manhole cover body and the well lid frame of the annular corresponding with manhole cover body, described Well lid frame include frame main part and arrange described frame main part bottom along described well The extension that the direction, the center of circle of lid frame extends；Described frame main part also includes being uniformly arranged on 4 through holes of its surrounding；Described manhole cover body also include being uniformly arranged on its surrounding along described 4 anti-theft pins that manhole cover body radially extends；Described manhole cover body covers at described well lid frame On, the bottom of described manhole cover body is connected to described extension, and described manhole cover body passes through 4 Described anti-theft pin correspondence inserts 4 described through holes of described frame main part and described well lid limit Frame matches；The setting of anti-theft pin so that manhole cover body and well lid frame lock together tightly , serve good anti-theft effect.Anti-stealing manhole can not be opened in the case of there is no instrument Well lid.Meanwhile, manhole cover body and well lid rim fits are become an entirety by anti-theft pin so that Even if having vehicle process from well lid during using, well lid is also not easy to fluff.In a word, Cover of inspection well good anti-theft effect of the present utility model, is firmly combined with ground, the out-of-date product of vehicle on road Raw noise is little.
