During current power load, Electricity customers is reluctant above fund input to equipment increase-volume, but with congenial means by low capacity
Privately it is replaced with jumbo transformator, carries out transgression for using electricity.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of transformer anti-theft fixing device and supports the use
Spanner, due to use shaped piece, effectively prevent user from opening voluntarily, change transformator.
To this end, the technical solution of the utility model is as follows:
A kind of transformer anti-theft fixing device, including matching used screw bolt and nut；Described bolt is by head and screw rod
Constitute；The sidewall of described head is cambered surface, and its sidewall is provided with two or more groove；Longitudinally it is provided with along it on described screw rod
Strip through hole or two strip holes；Described nut is provided with through hole.During use, after installing, utilize and disposably seal nut
Corresponding with the hole on bolt shut, form fixed structure.
A kind of transformer anti-theft fixing device, including fastener, matching used screw bolt and nut；Described bolt by head and
Screw rod is constituted；The sidewall of described head is cambered surface, and its sidewall is provided with two or more groove；On described screw rod along it longitudinally
It is provided with strip through hole；Described nut is provided with through hole；Described fastener is through the through hole on described nut and the length on described screw rod
Bar through hole, fixing nuts and bolt.Further, described fastener is alignment pin, straight pin or special-shaped pin.
Preferably, the axis of two grooves that described head is arranged is parallel or the extended line of the axis of two grooves be 30～
90 ° of angles；The extended line of the axis of the plurality of groove is between any two in 30～90 ° of angles.
A kind of with the described matching used spanner of transformer anti-theft fixing device, including the handle being sequentially connected with and function
The mating shapes of the sidewall of the head of portion, the shape of the inner surface of described function part and described bolt；Described function part interior
Surface configuration has two or more boss, the position of described boss to match with the position of the groove being arranged on described head.
This bolt head is arc, and general purpose tool cannot be removed stubborn, it is necessary to adapted special spanner operates with.And screw rod and spiral shell
There is through hole female junction, equipped disposable envelope, effectively prevents from usurping or private is opened the big lid of transformator and exchanged inner core for and increase capacity, steal
Electric energy.
