Description
Technical field
The utility model belongs to inspection well cover technical field, relates to a kind of anti-stealing manhole cover.
Background technology
A lot of underground pipeline is had in urban construction, such as sewer, underground gas pipeline, water supply pipe, power pipe, communication conduit, national defence pipeline etc., these pipelines will have an outlet of leading to ground every one section, inspection shaft is called to this section on ground by pipeline, catch pit port is usually concordant with ground, therefore need a lid, be used for the lid of lid inspection shaft, be inspection well cover.Inspection well cover is made with materials such as reinforced concrete, metal, reinforced plastics usually, and shape is based on circular and square.
But along with continuing to increase of urban construction, the generation of the problems such as inspection well cover is stolen is also more and more frequent, and inspection well cover is stolen both can cause no small economic loss, also can cause that pedestrian falls and wait danger simultaneously.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of anti-stealing manhole cover with anti-theft feature.
The purpose of this utility model realizes by following technical proposal: a kind of anti-stealing manhole cover, comprise inspection well cover and cast iron seat, it is characterized in that: described inspection well cover circumference is provided with some holddown grooves, described holddown groove notch is provided with gear edge, bolt is connected with by spring in described holddown groove, and by pressing bolt extrusion spring makes bolt be placed in holddown groove, also make bolt head and gear along offseting by spring compresses bolt head, now described bolt stretches out outside holddown groove, cast iron seat is provided with the locating hole of some connection cast iron seat inner periphery and the outer periphery, cast iron seat periphery is also connected with fixed bin, and described locating hole one end is positioned at fixed bin, described bolt extend in fixed bin by locating hole, and fixed by nut, and when described cast iron seat is contained on level ground, described fixed bin is placed in below ground.
First cast iron seat is arranged on level ground, load onto inspection well cover afterwards, and extrusion spring makes bolt be placed in holddown groove, is loaded by inspection well cover in cast iron seat inner circumferential, unclamp bolt and make bolt extend in fixed bin by locating hole, and fixed by nut, finally fixed bin will be built upper cement, owing to concealing coupling part, therefore avoid inspection well cover stolen, when needing to be serviced, as long as pry open the ground of fixed bin part.
As preferably, described nut also overlaps and has protective jacket.
Prevent from the cement of building from destroying bolt to be connected with nut.
As preferably, in described fixed bin, be also provided with magnetic patch.
Magnetic patch is set and conveniently can finds fixed bin, as long as look for magnetic areas, so that safeguard.
As preferably, fixed bin top is also provided with dismountable filter, and described magnetic patch is located at bottom filter.
Arranging filter is also destroyed by the cement of building in fixed bin to prevent.
Compared with prior art, the utility model tool has the following advantages:
First cast iron seat is arranged on level ground, load onto inspection well cover afterwards, and extrusion spring makes bolt be placed in holddown groove, is loaded by inspection well cover in cast iron seat inner circumferential, unclamp bolt and make bolt extend in fixed bin by locating hole, and fixed by nut, finally fixed bin will be built upper cement, owing to concealing coupling part, therefore avoid inspection well cover stolen, when needing to be serviced, as long as pry open the ground of fixed bin part.
