Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] An anti-theft electric energy metering box, such as Figures 1-4 As shown, it includes a box body 1, a box door 2 is rotatably connected to one side of the box body 1, an anti-theft component is fixedly connected to the upper end of the inner wall of the box body 1, and the anti-theft component includes a power supply 21, the power supply 21 is fixedly connected to the upper end of the inner wall of the box body 1, the positive pole of the power supply 21 is electrically connected to the alarm 20, and one side of the alarm 20 is electrically connected to the conductive block 2 19, and the alarm 20 and the conductive block 2 19 are both fixedly connected to the upper end of the inner wall of the box body 1;

[0025] The negative pole of the power supply unit 21 is electrically connected to the conductive block 11, and one end of the conductive block 11 is fixedly connected to the magnet 2 13 via the connecting rod 12. The conductive block 11 and the magnet 2 13 are both slidably connected to the upper end of the inner wall of the box body 1, and the conductive block 11 is in contact with the conductive block 2 19. The outer wall of the box body 1 is plugged with a magnet 18, and the magnet 18 and the magnet 2 13 are magnetically engaged. The side wall of the conductive block 11 is fixed with an elastic component for driving the conductive block 11 to reset. An insulating plug-in plate 10 is fixed to one side of the box door 2, and the insulating plug-in plate 10 is inserted between the conductive block 11 and the conductive block 2 19.

[0026] The box door 2 closes the side wall of the box body 1, and the elastic assembly is always in a compressed state when the box door 2 is closed and locked. The elastic assembly extrudes the conductive block one 11, and the conductive block one 11 slides on the top inner wall of the box body 1. The insulating plug plate 10 of the box door 2 is located between the conductive block one 11 and the conductive block two 19, which separates the conductive block one 11 and the conductive block two 19, and the conductive block one 11 and the conductive block two 19 are not conductive. The power supply 21 and the alarm 20 are not powered and will not alarm. Before the staff opens the box door 2, the magnet one 8 needs to magnetically attract the magnet two 13 through the box body 1. The position of the conductive block one 11 is fixed, and when the box door 2 is opened, the insulating plug plate 10 is separated from between the conductive block one 11 and the conductive block two 19. Since the position of the conductive block one 11 is fixed, the conductive block one 11 and the conductive block two 19 will not be in contact with each other, and the alarm 20 will not alarm. Non-staff opening the box door 2, without the magnet one 8 magnetically attracting the magnet two 13, the conductive block one 11 and the conductive block two 19 will be extruded by the elastic assembly and thus close to each other. The alarm 20 will be powered and will alarm. When the thief opens the box door 2 and does not use the magnet one 8, the alarm 20 will alarm in time. The electric energy metering box has a theft-proof effect, which prevents the devices in the electric energy metering box from being stolen and causes high maintenance costs.

[0029] As shown in Figure 2 , Figure 4 , the inner wall of the box body 1 is provided with a sliding groove 9 at the upper end. The conductive block one 11 and the magnet two 13 are both fixedly connected with a sliding block 14. The two groups of sliding blocks 14 are both in sliding connection with the sliding groove 9.

[0030] The shape of the sliding block 14 and the cross-sectional shape of the sliding groove 9 are both set as "convex" type, which prevents the sliding block 14 from being separated from the sliding groove 9.

[0031] As shown in Figures 3-4As shown, a lighting assembly is fixed to the upper end of the inner wall of the box 1, and the lighting assembly includes a lighting lamp 23. The lighting lamp 23 is fixed to the inner wall of the box 1. One group of terminals of the lighting lamp 23 is electrically connected to the positive pole of the power supply 21, and the other group of terminals is electrically connected to the conductive block three 22. The conductive block three 22 is fixed to the inner wall of the box 1, and the end of the conductive connecting plate 15 is fixed to the conductive plate 16, and the conductive plate 16 is in contact with the conductive block three 22.

[0032] When the staff uses magnet one 8 to magnetically attract magnet two 13, magnet two 13 pulls conductive block one 11 through connecting rod 12, and conductive block one 11 contacts conductive block three 22 through conductive connecting plate 15 and conductive plate 16 to conduct electricity. Current flows between power supply 21, lighting lamp 23, conductive block three 22, and conductive block one 11, and lighting lamp 23 is energized, which can provide illumination when the staff is repairing or reading the meter.

[0034] The heat dissipation opening 6 facilitates heat dissipation inside the electric energy meter box, and the dustproof plate 7 prevents dust from entering the box body 1 through the heat dissipation opening 6.

[0035] like Figure 1 As shown, a lock hole 3 is provided on the box door 2 , a knob 5 is rotatably connected to one side of the box door 2 , and a cover plate 4 for covering the lock hole 3 is fixedly connected to the side wall of the knob 5 .

[0036] The knob 5 is turned to turn the cover plate 4 to cover the lock hole 3 to prevent water or dust from entering the lock hole 3.

[0037] The working principle of the anti-theft electric energy meter box provided by the utility model is as follows:
