Abstract
The utility model relates to an electricity-larceny-prevention screw, which comprises a screw rod and is characterized by also comprising a round clamp table and a screw cap, wherein one side of the round clamp table is connected with the screw rod, the edge of the round clamp table is projected out of the screw rod, the screw cap is arranged at the other side of the round clamp table and is connected with the round clamp table through an easy-to-break rod, and the diameter of the easy-to-break rod is smaller than the diameter of the screw rod.
Description
Technical field
The utility model relates to electric power equipment field, more particularly, relates to a kind of anti-electricity-theft screw.
Background technique
Increase along with The development in society and economy and power consumption, the stealing problem becomes more and more outstanding in the society, and according to conservative estimation, the whole nation is stolen with a toll of 20,000,000,000 yuan because of electric energy every year, the development that this does not singly perplex power supply enterprise has also had a strong impact on the stable of national economic construction and society.
The model utility content
For addressing the above problem, the utility model provides a kind of anti-electricity-theft screw, comprise lead screw, it is characterized in that: described anti-electricity-theft screw also comprises a side and the circular card platform that described lead screw is connected, the edge protrudes from described lead screw, the screw cap that is arranged at described circular card platform opposite side, is connected with the circular card platform with easily broken bar; The diameter of described easily broken bar is less than the diameter of described lead screw.
Thus, when the lead screw mounting hole that submerges, when the circular card platform touches attachment face, continue firmly thread and can twist into two parts easily broken bar, prevent that electricity filching person from opening the electric power equipment without authorization.
According to a kind of anti-electricity-theft screw described in the utility model, it is characterized in that: the diameter of described easily broken bar is greater than half of described lead screw diameter.
Thus, make described easily broken bar have certain intensity, again when the lead screw mounting hole that submerges, when the circular card platform touches attachment face, continue firmly thread and can twist into two parts easily broken bar, prevent that electricity filching person from opening the electric power equipment without authorization.
According to a kind of anti-electricity-theft screw described in the utility model, it is characterized in that: the length of described easily broken bar is 2-4mm.
Thus, can prevent that easily broken bar accident from fractureing.
According to a kind of anti-electricity-theft screw of the present utility model, simple in structure, easy for installation, can prevent effectively that electricity filching person from opening the electric power equipment without authorization.
Description of drawings
Fig. 1 is a kind of anti-electricity-theft screw structural schematic representation of the present utility model.
Wherein 1 is lead screw, and 2 is the circular card platform, and 3 is easily broken bar, and 4 is screw cap.
Embodiment
Embodiment 1
A kind of anti-electricity-theft screw comprises the lead screw, circular card platform, easily broken bar, the screw cap that connect successively.The diameter of described easily broken bar is half of described lead screw external diameter, and length is 3mm.The big 5mm of external diameter of the described lead screw of diameter coin of described circular card platform.
During installation, elder generation's normal rotation anti-electricity-theft screw to lead screw is submerged in the mounting hole fully, the circular card platform is stuck on the attachment face more greatly because of diameter, this moment is more firmly to installation direction rotation screw cap, easily broken bar is at first twisted into two parts because of diameter, this moment, anti-electricity-theft screw lost screw cap, can't be disassembled again, namely finished installation.
According to a kind of anti-electricity-theft screw of the present utility model, simple in structure, easy for installation, can prevent effectively that electricity filching person from opening the electric power equipment without authorization.
