Abstract
The utility model relates to an anti-theft bolt which is a mechanical fastener. The anti-theft bolt comprises a bolt 1, a nut 2, an inclined hole 5 arranged in the central line direction of any place of the junction between the bolt 1 and the nut 2, and a male pin 3 arranged in the inclined hole 5. The utility model can be used for fastening any mechanical equipment required anti-theft, such as a steel tower, etc., of the erection equipment of electric lines. The utility model once installed, can not be detached unless completely destroyed. Thus the anti-theft action is truly played. The utility model is simple structure and convenient operation.
Description
The utility model relates to a kind of mechanical fastening device.
Existing bolt is made of screw bolt and nut.This bolt is easy to dismounting with spanner.In some machinery, as the power circuit spanning equipment---use this bolt on the iron tower, people are succeeded easily and worry to thief.For antitheft, there is the people on this bolt, to add a cover Anti-theft cap, also there is artificial this bolt to add a rivet, no matter but add a cover Anti-theft cap or increase a rivet, all can not reach real antitheft purpose.Because the still available socket wrench of bolt or the common wrench of adding a cover Anti-theft cap or increasing a rivet are dismantled with brute force.
The purpose of this utility model be make a kind of can really antitheft novel bolt.This bolt, just can not unload unless it is wracked once installing.
The purpose of this utility model is achieved in that anti-theft bolt is made up of bolt 1 and nut 2, centerline direction at bolt 1 and nut 2 joint any points has an inclined hole 5, this inclined hole 5 is positioned on bolt 1 and the nut 2 simultaneously, adorns the pin 3 that usefulness steel are made in inclined hole 5.
Fastening owing to being connected of bolt 1 of the present utility model and nut 2 adopting pin 3 that screw rod, nut are given, thus unless make that the utility model is thoroughly destroyed, just can not unload, thereby can really reach antitheft purpose.
The drawing of accompanying drawing is described as follows:
Accompanying drawing is a structural representation of the present utility model, wherein:
1-bolt 2-nut
The part that 3-pin 4-is fastened
The 5-inclined hole
Accompanying drawing has been described an embodiment of the present utility model.
By the anti-theft bolt that bolt 1 and nut 2 are formed, open an inclined hole 5 at the bolt 1 and the centerline direction of nut 2 joint any points, this inclined hole 5 is placed on bolt 1 and the nut 2 simultaneously, in inclined hole 5, adorn the pin that usefulness steel are made.The utility model can be used for the antitheft machinery of any needs, as the power circuit spanning equipment--and fastening the utility model of iron tower etc. is not only simple in structure, and uses also very convenient.
