Description

A kind of theft-proof manhole cover

Technical field

The present invention relates to technical field of burglary prevention, specially a kind of theft-proof manhole cover.

Background technique

Currently, being needed in urban and suburban roads and all kinds of pumping equipments more in provided underground such as water, electricity, communication, draining etc. Kind pipeline, also sets up the well head for draining and observing and overhauling subterranean pipe line, covers the most of using cast iron of well head The well lid of material manufacture, and only cover well lid on well seat, the well lid as made of traditional cast iron materials has certain Recovery value, and anti-theft measure currently used for well lid is very not perfect, does not have anti-theft function, so well lid is easily stolen, And it once loses, damage not only will cause to the facility protected and brings economic loss to national enterprise, but also be possible to lead The generation of cause accident, has seriously threatened the safety of the pedestrian and vehicle that walk on road, serious or even can pacify to the person Unpredictalbe injury is caused entirely, and social concern caused by the safety problem of well lid has become one in people's life Major hidden danger；Meanwhile well lid is easily movable on well seat, moves up and down once by external force, issues great noise, bring Very big noise pollution brings big inconvenience to people's lives；Furthermore traditional well lid is in some urban cultures that show In engineering, traditional well lid seems unsightly misfits with entire engineering very much very much, reduces the culture image in city, cannot Meet the needs of social development.

Many criminals steal the well cover for sewer used on highway at present, and many well lids all use coagulating cement instead at present Soil pours, but the well lid hardness that cement concrete pours is inadequate, the vehicle crushing that previous well lid all also travels when long.

Summary of the invention

The purpose of the present invention is to provide the well seats of a kind of telescopic rod of reverse side in well lid and well lid surrounding to constitute one A anti-theft device, under normal circumstances, the tail end of telescopic rod are stuck in lateral aperture, are in a kind of keyed in usually well lid in this way State prevents from being stolen, and when needing to open well lid inspection, by special key, passes through the rectangular key among well lid Hole, so that it may a kind of theft-proof manhole cover for opening well lid, to solve the problems mentioned in the above background technology.

To achieve the above object, the invention provides the following technical scheme: a kind of theft-proof manhole cover, including manhole cover body, The manhole cover body is made of well lid and well seat, and the centre of the well lid is equipped with rectangular keyhole, the inside of rectangular keyhole Equipped with rubber stopper, the outer periphery of the rectangular keyhole is equipped with fixed ring, and fixed ring is equipped with retaining rail, and retaining rail is welded on The reverse side of well lid, the rectangular keyhole are surrounded by reinforcing rib, and reinforcing rib and fixed ring are integrally formed, the reinforcing rib Outside is equipped with track semicircle, and the side of the track semicircle is equipped with telescopic rod.

Preferably, one end of the telescopic rod is equipped with pulley, and pulley is structure as a whole with telescopic rod, the side of the telescopic rod Face is equipped with spring support, and the spring support is welded on telescopic rod, and one end of the spring is fixed on well lid, spring it is another One end is connect with telescopic rod.

Preferably, the side of the well lid is equipped with well seat, and the inner side of the well seat is equipped with lateral aperture, the lateral aperture With telescopic rod in same level height.

Preferably, the side length of the rectangular keyhole is 20mm.

Preferably, the well lid is made with well seat of cast iron, is set on the well seat there are four lateral aperture, the depth of lateral aperture Degree is 16mm.

Preferably, the fixed ring is circle.

Compared with prior art, the beneficial effects of the present invention are:

(1) cylinder iron material is made well lid with well seat, and cast iron has very high hardness, while also having good anti- Rust；

(2) an anti-theft device is constituted in the well seat of the telescopic rod of the reverse side of well lid and well lid surrounding, in normal condition Under, the tail end of telescopic rod is stuck in lateral aperture, prevents from being stolen in the state that usually well lid is in a kind of keyed in this way, is needing to beat When the lid that drives a well checks, by special key, pass through the rectangular keyhole among well lid, so that it may open well lid；

(3) rubber stopper is housed on the rectangular keyhole among well lid, rectangular keyhole is prevented to be chronically exposed to road surface appearance Easily to be blocked by silt, rubber stopper is not limited by shape, and there is elasticity well, can firmly be stuck in rectangular keyhole, It is not easy to fall off.
