Abstract
A kind of anti-stealing manhole cover, it is made of Seat for manhole cover, inspection well cover and hinge pivot pin three parts, and there are two hinge seats for the side on Seat for manhole cover, and there is concave step at the both ends of two hinge seat axis holes；The side of inspection well cover is there are one hinge lug, and there are one hinge pin apertures in hinge lug；It is with the combination pivot pin that both ends are the round end head of a nail that inspection well cover is hinged together with manhole cover base, and locked in the pin hole of inspection well cover；The combination pivot pin is to follow closely the female Guan Ding of swelling with male cone, which is axis at the axis hole position of the hinge seat of inspection well seat, and the position in the pin hole of inspection well cover is pin.The inspection well cover manufactured using the technical program, because the round end head of a nail at the both ends of combination pivot pin is all sunk within the concave step at hinge seat axis hole both ends, along with combination pivot pin swelling in pin hole, so stealer can not extract the combination pivot pin and can not steal the inspection well cover, because the anti-stealing manhole cover only has three seat, lid, pin parts, so simple structure, at low cost.
Description
Technical field
The present invention relates to a kind of anti-stealing manhole covers.
Background technology
Currently, the anti-stealing manhole cover used is complicated, it is of high cost.
Invention content
The technical problem to be solved by the present invention is to provide a kind of simple structure, anti-stealing manhole cover at low cost.
The technical solution adopted by the present invention is that a kind of anti-stealing manhole cover, it is by Seat for manhole cover, inspection well cover and hinge pivot pin
Three parts are constituted, it is characterized in that：There are two hinge seats for side on Seat for manhole cover, and there is interior concave station at the both ends of two hinge seat axis holes
Rank；The side of inspection well cover is there are one hinge lug, and there are one hinge pin apertures in hinge lug；With the combination pivot pin that both ends are the round end head of a nail
Inspection well cover is hinged together with manhole cover base, and locked in the pin hole of inspection well cover；The combination pivot pin is followed closely with male cone
The female Guan Ding of swelling, the combination pivot pin are axis at the axis hole position of the hinge seat of inspection well seat, and the position in the pin hole of inspection well cover is
Pin.
Inspection well cover manufactured using above technical scheme, because the round end head of a nail at the both ends of combination pivot pin is all sunk to
Within the concave step at hinge seat axis hole both ends, combination pivot pin swelling in pin hole is added, so stealer can not pull out
Go out the combination pivot pin and the inspection well cover can not be stolen, because the anti-stealing manhole cover only has three seat, lid, pin parts, so construction letter
It is single, it is at low cost.
Description of the drawings
Fig. 1 is the organigram of the present invention.
Fig. 2 is the organigram of the combination pivot pin in the present invention.
In figure：1, Seat for manhole cover；2, inspection well cover；3, pivot pin is combined；3.1 male cone nails；3.2 female Guan Ding.
Specific implementation mode
