The present invention realizes the detachable installation of the electric meter box 1 by adding the fixed part 2 to the box body 12, and the limiting mechanism 3 only needs to be movably connected to the fixed part 2, avoiding the method of integrally forming the mounting platform at the four corners of the box body, and then directly connecting the box door to the box body through the limiting mechanism, thereby simplifying the box structure and having the advantage of being easy to process and form the electric meter box.

[0056] When installing the electric meter box 1, first connect the rod 31 on the limiting mechanism 3 to the box body 12, and the rod part of the rod 31 passes through the first screw hole 111 and extends a certain distance out of the box door 11, and then the rod 31 is connected to the limiting part 32 by threads. At this time, the limiting mechanism 3 can be rotated on the inner wall of the first screw hole 111 to cover the box door 11 and the box body 12, and use a specific tool to match the rod 31 with the first screw hole 111. At the same time, the rod 31 drives the limiting part 32 to rotate together, so that the limiting part 32 contacts the fixing part 2, and the box door 11 and the box body 12 are tightly fitted.

[0057] In summary, the anti-electricity theft device provided by the present invention has at least the following beneficial effects:

[0058] 1. The special anti-electricity theft device provided by the present invention adds a fixing part to the box body, and the limiting mechanism only needs to be movably connected with the fixing part to realize the detachable installation of the meter box, avoiding the method of integrally forming a mounting table at the four corners of the box body and then directly connecting the box door to the box body through the limiting mechanism, thereby simplifying the box structure and having the advantage of being easy to process and form the meter box.

The pressure sensor is arranged on the fixed part, and the alarm is arranged on the top of the box. When the box door is opened, a specific tool is used to loosen the insertion rod and the first screw hole on the box door. During the loosening process, since the limit part is fixedly connected to the insertion rod, the limit part is driven to rotate together, and finally the limit part is separated from the fixed part, and the box is opened. Because this device requires a specific tool to open, and since the limit mechanism is in contact with the fixed part, when criminals try to use violent means to open the meter box, the pressure sensor sends the monitored pressure value to the alarm system, and the alarm system issues an alarm command to the alarm.

[0060] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto.
