Abstract

The utility model discloses an anti-theft safety well cover, which comprises a cover body and a seat ring, wherein, the cover body is jointed and assembled on the seat ring through a pin shaft arranged on the seat ring and is produced by metal frames and rubber, and the metal frames are buried in the rubber. The cover body of the utility model is formed in one piece by the metal frames and the rubber, the rubber and the metal frames are closely fused and are difficult to separate; if someone wants to separate the metal frames from the rubber, the needed time is very long and the cover body uses fewer metal frames, thus the law breaker is difficult to benefit from the cover body, which plays a role of theft proofness to some extent and alleviates the municipal administration pressure.

Description

A kind of anti-theft security well lid

Technical field

The utility model relates to the used well lid of a kind of municipal engineering, and especially a kind of have antitheft and well lid safety warning function.

Background technology

The well lid that highway and municipal engineering are at present used generally has two kinds, and first kind is casting iron well lid, and second kind is cement well lid.Casting iron well lid mainly is to be irritated by the pig iron to cast type, because its raw materials used pig iron that is mainly, and the pig iron can utilize again, cause some illegal one's shares of expenses for a joint undertaking to steal well lid and process recovery, according to incompletely statistics the annual well lid in Beijing stolen, damage and be about more than 20,000, municipal sector will spend great amount of manpower and material resources well lid is replenished, keeps in repair for this reason, has wasted social resources.Though cement well lid is difficult for stolen, to make also fairly simplely, cement well lid exists outward appearance not attractive in appearance, uses defectives such as easy detrition for a long time.

The utility model content

At the problem that prior art exists, the purpose of this utility model is to provide a kind of anti-theft security well lid.

For achieving the above object, a kind of anti-theft security well lid of the utility model comprises lid, seat ring, and lid is fitted on the seat ring by the bearing pin that is provided with on the seat ring is hinged, and lid is made by metal framework and rubber, and metal framework is embedded in the rubber.

Further, also be coated with rubber layer on the supporting surface that matches with described lid on the described seat ring, the supporting surface that matches with lid on soffit that matches with seat ring on the lid and the seat ring is irregular concaveconvex structure, and two relief structured surface recessed to protruding, protruding to recessed mutual coupling, make between the fitting face of lid and seat ring tightly to engage mutually.

Further, also by hinged at least one the caution turnover panel that is equipped with of bearing pin, this caution turnover panel is depressed by the described lid that is fastened on the seat ring, and digs automatically after lid starts on the described seat ring, warns turnover panel and is provided with caution with reflective membrane or reflector.

Further, described caution turnover panel is under free state, automatically dig by balancing weight fixing on it, or dig automatically by the spring that is provided with on its jointed shaft, or by it being dug automatically the one side setting of jointed shaft deflection caution turnover panel center of gravity under the deadweight effect.

The utility model lid is one-body molded by metal framework and rubber, rubber and metal framework appearance connect and closely are difficult to peel away, if it is considerably less to want that metal framework is separated the metal framework that required time is grown very much and the lid body uses, the law-breaker is difficult to benefit from it, this has played antitheft effect to a certain extent, has alleviated municipal pressure.

The specific embodiment

Shown in Fig. 1,2,3 and 6, for a kind of anti-theft security well lid comprises lid 1, seat ring 2, lid 1 is made by metal framework and rubber, metal framework is embedded in the rubber, also be provided with a pair of flank 12 on lid 1 side, flank 12 constitutes with lid 1 one, and place, flank 12 corresponding ground is provided with two caution turnover panels 5; Seat ring 2 sides are provided with bearing pin 14, bearing pin 14 hinged are fitted in seat ring 2 on of lid 1 by being provided with on the seat ring 2, the supporting surface 21 that seat ring 2 matches with lid 1 is a ring surface, also be coated with rubber layer on the supporting surface, the supporting surface 21 that matches with lid on the soffit 13 that matches with seat ring 2 on the lid 1 and the seat ring 2 is irregular concaveconvex structure 3, and two concaveconvex structures 3 surface recessed to protruding, protruding to recessed mutual coupling, make between the fitting face of lid 1 and seat ring 2 tightly to engage mutually.

Shown in Fig. 4,5, place, flank 12 corresponding ground is provided with is free frame 22 to be used for placing caution turnover panel 5, caution turnover panel 5 is connected the oral area of sky frame 22 by bearing pin 51, size, the degree of depth of caution turnover panel 5 and empty frame 22 is complementary and guarantees that caution turnover panel 5 can overturn in empty frame 22, the one side of caution turnover panel 5 is fixed with balancing weight 52, reflective membrane 53 is posted on the two sides, is fixed with the turnover panel placed face down of balancing weight 52; Caution turnover panel 5 is not subjected to the pressure limit of flank 12 when lid 1 starts, and warn turnover panel 5 and begun turning by the influence of balancing weight 52 this moment, warns for pedestrians, vehicle by the reflective membrane 53 on the caution turnover panel 5 of erect, prevents dangerous the generation.

As shown in the figure, lid 1 is to be made by metal framework and rubber, metal framework is embedded in the rubber, rubber and metal framework appearance connect and closely are difficult to metal framework and rubber are separated, if it is considerably less to want that metal framework is separated the metal framework that required time is grown very much and lid 1 uses, the law-breaker is difficult to benefit from it, and this has played antitheft effect to a certain extent; Because lid 1 is made up of two kinds of raw materials, lid 1 existing rigidity is prevented the pressure effect, and also flexible cushioning effect has played protective action to driving vehicle, and all having splendid effect aspect resistance to compression, the anti-natural force, prolonged the application life of well lid simultaneously; Two concaveconvex structures 3 are irregular shape, and two concaveconvex structures 3 surface recessed to protruding, protruding to recessed mutual coupling, if lid 1 is taken the use of another mouthful well, will can not use at another mouthful well because shape does not match.
