Abstract
The present invention relates to a kind of inspection well cover, it includes Seat for manhole cover, support and cover plate of manhole, it is characterized in that：There are multiple support bases on the madial wall of Seat for manhole cover lower part, is connected with support with pivot pin on support base, the other end of support is connected to pivot pin on the sliding slot below cover plate of manhole；The pivot pin is that retreating-proof combines pivot pin；Automobile reflection plaster is posted on support and cover plate of manhole periphery；Take this kind of inspection well cover that the technical program manufactures, because being that three Seat for manhole cover, support and cover plate of manhole components are linked together with retreating-proof combination pivot pin, the cover plate of manhole can not be stolen because stealer cannot pull up retreating-proof pivot pin, so good anti-theft effect.
Description
Technical field
The present invention relates to a kind of inspection well covers.
Background technology
Inspection well cover is usually to be connect with screw or pin with cage at present, and because screw is easily backed out, the clamp of pin is easy
It removes, so inspection well cover is easily stolen；General inspection well cover is all disposed on road surface, therefore is crushed easily；When encounter heavy rain to
When outer water spray, the flow that inspection well cover is easy to be ejected again washes away, and trap is formed because being unable to automatic warning passerby.
Invention content
The technical problem to be solved by the present invention is to, a kind of antitheft, resistance to compression is provided, will not be flushed away when inspection shaft is sprayed water outward,
It can open up and prop and inspection well cover that anti-passerby crashes into automatically.
We's invention adopts the technical scheme that inspection well cover, it includes Seat for manhole cover, support and cover plate of manhole, feature
It is：There are multiple support bases on the madial wall of Seat for manhole cover lower part, support, the other end of support are connected with pivot pin on support base
It is connected on the sliding slot below cover plate of manhole with pivot pin；The pivot pin is that retreating-proof combines pivot pin；Support and cover plate of manhole periphery
On post automobile reflection plaster.
The retreating-proof combines pivot pin, it is composed of hero cone nail and female cylinder nail；The male cone nail, left end is round end
The head of a nail, centre are cylindrical, and right end is the cone bodily form with annular step fastener step；The female Guan Ding, right end are tack, stud
Cap, centre are cylindrical, and left end is the tubular that internal diameter is slightly less than the male annular step fastener stepped diameters of cone nail；The round tube inner wall
On have and there is crack to be divided into more valves with the matched ring grab platform of the annular step fastener step of male cone nail, the pipe.
Take this kind of inspection well cover that above technical scheme manufactures, because be with retreating-proof combination pivot pin Seat for manhole cover,
Support and three components of cover plate of manhole link together, and the inspection well cover can not be stolen because stealer cannot pull up retreating-proof pivot pin
Plate, so good anti-theft effect；In being located at below cover plate of manhole because of the supporting point that the cover plate of manhole is supported when being flushed with road surface
Between position, the several herringbone diagonal braces of symmetrical two or more supports compositions are transmitted to the pressure above cover plate of manhole following inspection shaft
Cage, so its resistance to compression；Because there is the supporting handle cover plate of manhole to link together with Seat for manhole cover, when raining in torrents, inspection shaft sprays from inside to outside
The cover plate of manhole will not be flushed away when water；Because having sliding slot below the cover plate of manhole, so the support is movable supporting, when the inspection shaft
When lid internal water pressure is larger, the power sprayed water upwards can open up the cover plate of manhole automatically, and make original bearing diagonal upper end to
Outer sliding becomes upright support and can automatically open to prop the cover plate of manhole, because the cover plate of manhole can support and be fixed on the inspection shaft
The top of mouth, but because posting automobile reflection plaster in the support and cover plate of manhole periphery, multiple supports constitute roll guard, so
Passerby can be warned and can effectively prevent passerby from crashing into the inspection shaft.
Description of the drawings
Fig. 1 is the section view organigram of the present invention.
Fig. 2 is the organigram when cover plate of manhole in the present invention is propped.
Fig. 3 is the retreating-proof combination pivot pin organigram that the present invention uses.
In figure：1, Seat for manhole cover；1.1, support base；1.2, pivot pin；1.2.1 hero cone nail；1.2.2 female cylinder nail；2, it supports；3,
Cover plate of manhole；3.1, sliding slot.
Specific implementation mode
In Fig. 1,2,3, inspection well cover provided by the invention, it includes Seat for manhole cover, support and cover plate of manhole, feature
It is：In Seat for manhole cover（1）There are multiple support bases on the madial wall of lower part（1.1）, support base（1.1）On use pivot pin（1.2）Connection
There is support（2）, support（2）Other end pivot pin（1.2）It is connected to cover plate of manhole（3）Following sliding slot（3.1）On；The axis
Pin（1.2）Pivot pin is combined for retreating-proof；Support（2）And cover plate of manhole（3）Automobile reflection plaster is posted on periphery.
The retreating-proof combines pivot pin, it is followed closely by hero cone（1.2.1）It is followed closely with female cylinder（1.2.2）It is composed；The hero
Cone nail（1.2.1）, left end is the round end head of a nail, and centre is cylindrical, and right end is the cone bodily form with annular step fastener step；Institute
State female Guan Ding, right end is the round end head of a nail, and centre is cylindrical, and it is straight that left end is that internal diameter is slightly less than the male annular step fastener step of cone nail
The tubular of diameter；Have on the round tube inner wall has crack with the matched ring grab platform of the annular step fastener step of male cone nail, the pipe
It is divided into more valves.
