Abstract
The utility model discloses a center hexagonal anti-theft bolt. The center hexagonal anti-theft bolt comprises a bolt head and a bolt rod, wherein the upper surface of the bolt head is provided with a hexagonal groove, the center part of the hexagonal groove is provided with a columnar embossment, the external side face of the bolt head is further provided with two through holes intersected in cross form. The center hexagonal anti-theft bolt provided by the utility model is delicate in design, simple and easy to use, and completely avoids the phenomenon that the conventional screw is easy to demount; is low in invested cost and wide in application foreground.
Description
Technical field
The utility model relates to a kind of anti-theft bolt, particularly hexagonal anti-theft bolt in a kind of center of circle.
Background technique
In order to reduce the generation of electric power facility larceny case, in the processing procedure to such event, find fundamentally to allow the electricity filching person effective measures that are only the radical cure stealing at one's wit's end of having no way of doing it.Because the structural feature of conventional screw, add the defective of traditional locking method, use some fastened tools commonly used, as: screw-driver, spanner, pipe wrench etc. just can be opened easily, thereby reach stealing, steal criminal intent such as copper, cause losing of electric energy, electric power facility, the also amateur operator's of serious threat personal safety simultaneously.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and be convenient to install to replace, use simple, and can only be fastening with special tool, hexagonal anti-theft bolt in a kind of center of circle of dismounting.
Hexagonal anti-theft bolt in a kind of center of circle includes bolt head and screw rod, and its structure outline is:
The groove of hexagonal in the upper surface of bolt head is provided with is provided with the projection of column in the center portion of interior hexagonal groove, also be provided with the two through hole that is cross cross arrangement at the outer side surface of bolt head.
Hexagonal anti-theft bolt in the center of circle of the present utility model, the sealing hole that the seal sealing lead is used after can utilizing two two through hole that are cross cross arrangement as the fastening back of electric energy meter Chuanfeng's line, utilize corresponding inner hexagon spanner to carry out the dismounting of hexagonal anti-theft bolt in this center of circle, during use, the normal screws that only needs to have now electric energy meter, transformer replaces with that the hexagonal anti-theft screw replaces its original fastening screw in the center of circle of model unanimity.A simple step can allow the electric power facility safe antitheft, and so both convenient the replacement can be promoted again on a large scale.
Described columnar projections is columned projection.
The axial direction of described through hole is perpendicular to the axial direction of bolt head.
In sum, the utility model following advantage compared to existing technology:
Hexagonal anti-theft bolt deft design in the center of circle of the present utility model, be simple and easy to usefulness, avoided the readily removable phenomenon of removing of conventional screw fully; Input cost is cheap, and application prospect is extensive.
