Abstract
An anti-theft bolt, which provides a fastening part to avoid the electric equipments on the electric power lines such as voltage transformers to be stolen. The structure of the anti-theft bolt is that a stopping pin is arranged at the combination of the bolt and the nut along the axial line direction. The structure of the anti-theft bolt is reasonable, the operation is convenient, and the utility model has the anti-theft function, effectively and reliably prevent the fastened electric equipments to be stolen. The utility model can be widely used, being suitable for various anti-theft situations.
Description
Affiliated technical field
The utility model relates to a kind of fastening piece, specifically is the anti-theft bolt that is used for electric power facilities such as fastening transformer on a kind of power circuit.
Background technique
Along with rural power grids are constantly newly-built and universal, bring great benefit to vast farmers.But, under individual interest drives, will steal the approach that electric power facility " is built up a family fortune and controlled richness " as them because minority of peoples are very weak in the understanding of law.The stolen incident of electric wire, switchboard and transformer takes place in many in recent years places repeatedly, causes power circuit to interrupt, and brings massive losses for country and society.And this case is at present also in rising trend, so power department presses for the anti-theft bolt of electric power facility such as a kind of fastening transformer, avoids the stolen of electric power facility such as transformer, ensures that the power circuit conveying is unimpeded.
Summary of the invention
The purpose of this utility model is to avoid the appearance of above-mentioned stolen phenomenon, and provide a kind of simple in structure, use reliable, easy to operate, and theftproof performance is fine, can avoid electric power facility such as transformer stolen, ensures that effectively power circuit carries unimpeded anti-theft bolt.
The purpose of this utility model reaches by following technical measures: this anti-theft bolt is on the basis of existing conventional bolt and nut, in addition again in the connecting part of the mutual interlock of screw bolt and nut, newly establishes a stop pin along axial direction.This stop pin is straight pin or taper pin.
The beneficial effects of the utility model are: this anti-theft bolt is rational in infrastructure, and is easy to use, has anti-theft feature, can prevent effectively reliably that fastened electric power facilities such as transformer are stolen.And its use extensively, can be used for various antitheft occasion.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The figure number explanation:
Embodiment
The utility model is described further below in conjunction with drawings and Examples: this anti-theft bolt also comprises a traditional bolt 1 and nut 4, can be with their bar long and thickness extend respectively and thicken.Newly establish a conical stop pin 5 in addition again in the connecting part of this bolt 1 and nut 4 mutual interlocks, and along axial direction.The hole that holds this stop taper pin 5 can be bolt 1 and nut 4 and packing ring 3 with fastened object 2 fastening good after, again in bolt 1 and nut 4 mutual interlock connecting parts, and on axial direction, bored after the taper hole, more conical stop pin 5 has been squeezed in the taper hole of being bored.The hole that holds this stop taper pin 5 also can be just good by preboring before bolt 1 and nut 4 also are not used in fastened object 2.Here it is choose earlier a pair of with want the identical exemplar of fastened object thickness, then with bolt 1 and nut 4 and packing ring 3 with selected exemplar fastening good after, again in the connecting part of bolt 1 and nut 4 mutual interlocks, and after the axial direction brill is gone up taper hole, conical stop pin 5 is not squeezed in the taper hole that is bored, but bolt 1 and nut 4 are turned on, and annotate and go up the pairing mark.Up to the job site they are pressed mark pairing will fastened object 2 fastening good after, ability is squeezed into conical stop pin 5 in the taper hole of institute's preboring., then can eliminate in fastening good a bit dislocation later on as institute's preboring taper hole by the thickness of adjusting packing ring 3.This anti-theft bolt has only with special instrument just can be turned on, and the thief can't turn at all, thereby reaches antitheft purpose.
Claims (2)
1. an anti-theft bolt includes bolt (1), nut (4) and packing ring (3), it is characterized in that newly establishing a stop pin (5) in the connecting part of bolt (1) and the mutual interlock of nut (4) along axial direction.
2. anti-theft bolt according to claim 1 is characterized in that stop pin (5) is straight pin or taper pin.
