It is more convenient to install when industry, it is time saving and energy saving, it is greatly improved working efficiency；And good anti-theft effect, electric power facility are not easy to be stolen.
To achieve the goals above, the technical solution adopted by the present invention is as follows：
The socket cap top surface of a kind of transmission tower anti-theft nut, including socket cap nut body, the socket cap nut body is equipped with
The left boss and right boss being centrosymmetric relative to end face center；The upper right quarter in the left boss section is left boss angle,
The lower left quarter in the right boss section is right boss angle, and the left boss angle is equal in magnitude with right boss angle；
The right edge of the left boss angle be located at the left side of the vertical center line of socket cap top surface and with its keeping parallelism；
The left side of the right boss angle be located at the right side of the vertical center line of socket cap top surface and with its keeping parallelism；
The length of the left side of the right edge of the left boss angle and the right boss angle is all higher than or is equal to the cylinder crown
The radius in face 1.
As a further improvement on the present invention, the external side of the left boss is arc, outer with socket cap top surface
Circumferential surface coincides.
As a further improvement on the present invention, the external side of the right boss is arc, outer with socket cap top surface
Circumferential surface coincides.
As a further improvement on the present invention, the left boss angle is less than or equal to 90 °.
As a further improvement on the present invention, the left boss angle is less than or equal to 60 °.
Compared with prior art, obtained by the present invention to have the beneficial effect that：
The present invention has simple in structure, easy to operate and reliable feature, and the component that the present invention is suitable for transmitting electricity in tower bar fastens
Connection, can be tightened with screwdriver, facilitate the installation of transmission of electricity tower bar；Mating specific purpose tool pine must be used when overhauling nut
It opens, cannot be unclamped with common screwdriver and spanner, power transmission tower rod unit can be effectively prevent stolen, ensure transmission line safety
Operation.
