Abstract
The present invention relates to a kind of manhole cover anti-theft pivot pins, it is used exclusively for the hinge of Seat for manhole cover and inspection well cover and plays the pivot pin of anti-theft function, this kind of manhole cover anti-theft pivot pin, it is composed of hero cone nail and female cylinder nail；The manhole cover anti-theft pivot pin manufactured using the technical program, because the round end head of a nail at the both ends of the pivot pin is all sunk within the concave step at hinge seat axis hole both ends, along with pivot pin swelling in pin hole, so stealer can not extract the pivot pin and can not steal the inspection well cover, so good anti-theft effect；Because this kind of manhole cover anti-theft pivot pin only has male cone nail and female pipe to follow closely two parts, so simple structure, at low cost.
Description
Technical field
The present invention relates to a kind of manhole cover anti-theft pivot pins.
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.
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, manhole cover anti-theft pivot pin at low cost.
The technical solution adopted by the present invention is that a kind of manhole cover anti-theft pivot pin, it is used exclusively for Seat for manhole cover and inspection shaft
The hinge of lid and the pivot pin for playing anti-theft function, it is characterized in that：This kind of manhole cover anti-theft pivot pin, it is by hero cone nail and female cylinder nail
It is composed；The male cone nail, left end is the round end head of a nail sunk in Seat for manhole cover hinge seat axis hole concave step, and centre is circle
Cylinder shape, right end are the cone bodily form；The female Guan Ding, right end are the tack, stud for sinking to inspection well seat hinge seat axis hole concave step
Cap, centre are cylindrical, and left end is the tubular that internal diameter is slightly less than male cone nail cone body diameter；The cone body of hero cone nail is exerted oneself
The pipe for being pressed into female Guan Ding is domestic next, be combined into the manhole cover anti-theft pivot pin, hinge seat of the combination pivot pin in inspection well seat
Axis hole position is axis, and the position in the pin hole of inspection well cover is pin.
The manhole cover anti-theft pivot pin manufactured using above technical scheme, because the pivot pin both ends the round end head of a nail all
It sinks within the concave step at hinge seat axis hole both ends, pivot pin swelling in pin hole is added, so stealer can not
It extracts the pivot pin and the inspection well cover can not be stolen, so good anti-theft effect；Because this kind of manhole cover anti-theft pivot pin only have male cone nail and
Female pipe follows closely two parts, so simple structure, at low cost.
Description of the drawings
Fig. 1 is the organigram of the present invention.
Fig. 2 is the use schematic diagram of the manhole cover anti-theft pivot pin in the present invention.
In figure：1, male cone nail；1.1, the round end head of a nail；1.2, cylinder；1.3, cone body；2, female Guan Ding；2.1, tack, stud

Specific implementation mode
In Fig. 1,2, a kind of manhole cover anti-theft pivot pin provided by the invention, it is used exclusively for Seat for manhole cover and inspection well cover
Hinge and play the pivot pin of anti-theft function, it is characterized in that：This kind of manhole cover anti-theft pivot pin, it is followed closely by hero cone（1）With female cylinder
Nail is composed；The male cone nail（1）, left end is to sink to Seat for manhole cover（3）The round end head of a nail in hinge seat axis hole concave step
（1.1）, centre is cylinder（1.2）Shape, right end are cone body（1.3）Shape；The female Guan Ding（2）, right end is to sink to inspection well seat
The round end head of a nail of hinge seat axis hole concave step（1.1）, centre is cylinder（1.2）Shape, left end are that internal diameter is slightly less than male cone nail
（1）The tubular of cone body diameter；Hero cone nail（1）Cone body firmly be pressed into female Guan Ding（2）Pipe it is domestic next, be combined into
The manhole cover anti-theft pivot pin, which is axis at the axis hole position of the hinge seat of inspection well seat, in the pin hole of inspection well cover
Position is pin.
