Description
Technical field
The utility model relates to a kind of bolt.
Background technique
Distribution wire is the lifeline of electric power enterprise, and controller switching equipment is the guarantee that is related to residential electricity consumption and corporate economy's income.Can cause serious potential safety hazard after power equipment is stolen, when influencing the normal electricity consumption of resident, increase maintainer's workload, also can have a strong impact on the economic well-being of workers and staff of company simultaneously.The distribution transformer robbery accident happens occasionally, and is to exhaust the people and drain the treasury.
Cause that the stolen main cause of controller switching equipment is that equipment only plays fixing effect with bolt, and this bolt does not have anti-theft feature, this has just given theft one's share of expenses for a joint undertaking chance.
The nut of plain bolt (nut) is the plane Hexagon, and doing like this is to loosen, tighten with instruments such as spanner, plum blossoms in the construction for convenience; Because of instruments such as spanner, plum blossom use generally, give the stolen condition that provides of controller switching equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-theft bolt with anti-theft feature.
To achieve these goals, the technical solution of the utility model is: anti-theft bolt, and it is formed by screw rod and with the supporting nut of screw rod, and it is characterized in that: being shaped as of nut is cylindrical, and an end face of nut is provided with 2-20 circular groove.
Described circular groove the best is 2-4.
The beneficial effects of the utility model are: nut be designed to cylindrical be for the one's share of expenses for a joint undertaking that avoids theft with loosening tool nuts such as existing spanners, and circular groove more than 2 is set, so that send, tightly with special tool at the end face of nut more; Have only special tool just can send, tightly, thereby the utlity model has anti-theft feature.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of nut of the present utility model;
Fig. 3 is the structural representation of special tool;
Among the figure: 1-screw rod, 2-nut, 3-circular groove, 4-special tool.
Embodiment
As shown in Figure 1 and Figure 2, anti-theft bolt, it is formed by screw rod 1 and with the supporting nut 2 of screw rod, and being shaped as of nut 2 is cylindrical, and an end face of nut 2 is provided with 4 circular grooves (can adopt 2, also can adopt more a plurality of).
As shown in Figure 3, special tool 4 design has been adopted corresponding with nut (nut) 2 cylindrical, and the part semicolumn is hollowed out, interrupts, and has welded the pin of two corresponding circle connected in stars in the plane, has high mechanical properties.Time spent only needs in the pin corresponding circle connected in star, clockwise or be rotated counterclockwise, anti-theft screw cap can be loosened, tighten operation.
