Abstract
The utility model provides an anti-theft fastener which comprises a bolt, a nut matched with the bolt and a mounting pin connecting the bolt and the nut, wherein the bolt is provided with an outer thread, the nut is provided with an inner thread matched with the outer thread, the bolt is provided with a through hole, the nut is provided with a mounting hole corresponding to the through hole, and the mounting pin is arranged in the through hole and the mounting hole. Since the mounting pin is arranged in the through hole and the mounting hole, after assembled, the mounting pin can hardly be pulled out and the nut cannot be unscrewed; therefore, the anti-theft effect is achieved.
Description
Technical field
The utility model relates to a kind of anti-theft fastening piece.
Background technique
The existing fastening piece that is used for facilities such as high low pressure electric power pylon, transformer, bridge, freeway guardrail is generally common bolts and nuts.Yet the fastening means of this bolts and nuts is easy to the dismounting by the people, and steals material, causes very big loss.
Summary of the invention
The technical problem that the utility model will solve provides a kind of easy to operate, the anti-theft fastening piece that cost is low.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: comprise bolt, and and the bolt nut engaged, and the mount pin of connecting bolt and nut; Said bolt is provided with outside thread, and said nut is provided with the internal thread that cooperates with outside thread; Said bolt is provided with through hole, and said nut is provided with and the corresponding mounting hole of through hole, and said mount pin is arranged in through hole and the mounting hole.
Further, said mounting hole is a blind hole, and the degree of depth is greater than through hole.
The anti-theft fastening piece of the utility model because said mount pin is arranged in through hole and the mounting hole, after installing, just is difficult to transfer to mount pin, has so just twisted motionless nut, thereby has played the effect of antitheft.
Description of drawings
Fig. 1 is the schematic representation of the utility model anti-theft fastening piece.
Embodiment
In the present embodiment, with reference to Fig. 1, said anti-theft fastening piece comprises bolt 1, and and bolt 1 nut engaged 2, and the mount pin 3 of connecting bolt 1 and nut 2; Said bolt 1 is provided with outside thread, and said nut 2 is provided with the internal thread that cooperates with outside thread; Said bolt 1 is provided with through hole 10, and said nut 2 is provided with and through hole 10 corresponding mounting holes 20, and said mount pin 3 is arranged in through hole 10 and the mounting hole 20.After installing, just be difficult to transfer to mount pin 3, so just twisted motionless nut 2, thereby play the effect of antitheft.
Wherein, said mounting hole 20 is a blind hole, and the degree of depth is greater than through hole 10.
The anti-theft fastening piece of the utility model because said mount pin is arranged in through hole and the mounting hole, after installing, just is difficult to transfer to mount pin, has so just twisted motionless nut, thereby has played the effect of antitheft.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
