Description

How to use anti-theft screw and its supporting tightening device

technical field

The invention relates to the technical field of electricity-stealing prevention in electric power systems, in particular to an anti-electricity-stealing screw and a method for using a matching tightening device thereof.

Background technique

With the development of social economy and the increase of electricity consumption, the problem of electricity theft has become more and more prominent in the society. According to conservative estimates, the annual loss of electricity due to theft of electricity in the whole country reaches 20 billion yuan, which not only plagues the development of power supply enterprises, but also It also seriously affected the country's economic construction and social stability. At present, there are various methods of stealing electricity in society. In order to prevent electricity theft, people design the meter cover on the junction box of the electric energy meter as a one-off, or design the connecting screw mounting holes of the meter cover as countersunk mounting holes. And a series of methods such as plugging a plastic cover on the installation hole, even screwing the screw in and breaking the head, etc. However, these methods are either laborious, time-consuming and costly, or have poor protection effects, or make the meter a disposable product, causing unnecessary waste and environmental pollution. These are obviously not suitable for a modern society that advocates energy conservation and environmental protection. .

Contents of the invention

In view of this, the object of the present invention is to provide an anti-stealing screw that can prevent non-workers from randomly opening the electric energy meter to steal electricity, and can facilitate staff to overhaul the electric energy meter. In addition, the present invention also provides an anti-theft screw. A matching tightening device for an electric screw and a method for using the same.

In order to achieve the above object, the anti-stealing screw includes a screw rod and a screw head, the outer surfaces of the screw rod and the screw head are all provided with threads, and a columnar hole is arranged at the center of the top of the screw head, and the columnar hole is A spherical hole is arranged symmetrically on the left and right sides of the bottom of the hole;

The matching tightening device of the anti-stealing screw includes a knife handle, a knife handle and a knife head. They are respectively hinged with the handle of the knife, and the ball ends can be bent at 90 degrees to both sides respectively, and an anti-slip sleeve is arranged on the handle of the knife.

The method for using the supporting tightening device of the anti-stealing screw includes the following steps:

Step 1: Place the screw rod of the screw vertically in the corresponding threaded hole on the cover by hand and screw it in lightly;

Step 2: When the screw is screwed in more than half and cannot be further screwed in by hand, the handle of the tightening device is vertically closed and inserted into the cylindrical hole of the screw head;

Step 3: Hold the handle of the knife and apply force downwards to bend the knife head 90 degrees to both sides, and snap it into the two spherical holes at the bottom of the cylindrical hole;

Step 4: Hold the knife handle tightly and rotate it to one side until the screw head is completely screwed in;

Step 5: Lift up the knife handle by applying force upwards, so that the knife head can be restored to a vertical state and taken out.

The beneficial effects of the present invention are as follows: 1. The present invention prevents non-workers from unscrewing the screws by setting specific screws and matching screw-in devices, thereby protecting the safety of devices such as electric meters, thereby preventing the occurrence of electricity theft incidents. 2. The anti-stealing screw of the present invention can also be made into various specifications, so as to be suitable for different electrical equipment and play a good protective effect on it, that is, the present invention has good versatility. 3. The anti-stealing screw of the present invention can be unscrewed with a specific supporting tool, which enables the maintenance personnel to test and repair the electrical equipment at any time, improves the service life of the electrical equipment, and avoids waste. Generally speaking, the present invention has the advantages of simple structure, convenient use, remarkable effect, etc., and has a good inhibitory effect on illegal electricity theft.

Detailed ways

As shown in Figure 1 and Figure 2: an anti-tampering screw, including a screw 2 and a screw head 1, the screw head 1 is arranged at one end of the screw 2, the outer surface of the screw 2 and the screw head 1 Threads are all provided, and the screw head 1 can be screwed in completely during use to increase the protective effect. A columnar hole 3 is provided at the center of the top of the screw head 2 , and a spherical hole 4 is respectively provided on opposite sides of the bottom of the columnar hole 3 .

As shown in Figure 3 and Figure 4: the matching tightening device of the anti-stealing screw includes a knife handle 5, a knife handle 6 and a knife head 7, one end of the knife handle 6 is welded to the knife handle 5, and the other end is welded to the knife head 7, Wherein, for the convenience of applying force during use, an anti-slip cover is set on the knife handle 5 . The cutter head 7 is two ball studs distributed side by side, and the ball studs are hinged with the handle 6 respectively, so that the ball studs can be bent at 90 degrees to both sides respectively.

The method of using the supporting tightening device of the anti-stealing screw is as follows: firstly place the screw rod 2 of the screw vertically in the corresponding threaded hole on the cover by hand and screw it into a certain distance; And when it is impossible to continue screwing in by hand, the handle 6 of the tightening device is vertically closed and inserted into the columnar hole 3 of the screw head 1; position, apply a slight force downwards, so that the two hinged ball rods on the knife head 7 are bent to both sides until they are bent to 90 degrees and snap into the two spherical holes 4 at the bottom of the cylindrical hole 3; secondly, hold the knife handle 5 Rotate hard to one side until the screw head 1 is completely screwed in; finally, apply force upwards to lift the knife handle 5, so that the two ball ends on the knife head 7 gradually return to the vertical state and take them out.

The anti-stealing screw disclosed by the present invention, because of its special structure, it is difficult for ordinary people to screw it in or out without the help of supporting tools. Therefore, it is easy to manufacture into various specifications and is widely used in various The assembly of electrical instruments and meters can effectively prevent criminals from modifying or destroying electric energy meters. In addition, the anti-stealing screw disclosed by the present invention can be unscrewed with specific supporting tools, which is convenient for maintenance personnel to test and repair electrical equipment at any time, improves the service life of electrical equipment, and avoids unnecessary pollution with waste.
