[0019] Reference Figure 1-7As shown, the anti-theft electricity meter of the present invention includes a housing 1, a housing cover 2 located at the upper end of the housing 1, and a terminal block 3 located at the rear end of the housing 1. A first flip cover 4 is located at the lower end of the housing cover 2, and a second flip cover 5 is located at the lower end of the housing 1. The housing 1 and the housing cover 2 are fixed to each other on both sides of the front end by first screws 6. A first seal seat 7 is located on the housing cover 2 corresponding to the first screw 6, and a plastic seal cap 8 is located on the first seal seat 7. The plastic seal cap 8 is provided with a positioning flat surface 9 and a first seal hole 10 communicating with the first seal seat 7. A barb 11 is located on the positioning flat surface 9 of the plastic seal cap 8, and first slots 12 are located on either side of the barb 11. The provision of the first slots 12 imparts elasticity to the barb 11. A hanging slot 13 is located within the first seal seat 7 to engage with the barb 11. The upper ends of the second flip cover 5 are connected to the ends of the housing cover 2 via rotating shafts 14. The middle portions of the second flip cover 5 are fixed to the housing 1 via second screws 15. The second screws 15 are provided with second lead-sealing holes 16. This structure ensures that the housing cover 2 can only be opened when both seals are removed simultaneously, providing a double security feature.

[0020] Preferably, one end of the first flip cover 4 is rotatably connected to the connecting shaft 18 of the housing 1 through an open shaft hole 17, and the other end of the first flip cover 4 is fixed to the housing cover 2 via a third screw 19. A second seal seat 20 is provided on the first flip cover 4 at a position corresponding to the third screw 19, and a second seal cap 21 is provided in the second seal seat 20. The second seal cap 21 prevents the first flip cover 4 from being opened illegally.

[0021] Preferably, the bottom of the plastic lead sealing cap 8 is provided with a bayonet 22 for engaging with the first screw 6, and the bayonet 22 is provided with circumferentially arranged retaining ribs 23. The bayonet 22 secures the top of the first screw 6, thereby ensuring its own stability and preventing the first screw 6 from loosening.

[0022] Preferably, the second seal cap 21 is provided with a second slot 24 and a first positioning flange 25, and the second seal seat 20 is provided with a second positioning flange 26 that engages with the first positioning flange 25. The engagement of the first positioning flange 25 and the second positioning flange 26 prevents the second seal cap 21 from falling off.

[0023] Preferably, a groove 27 is provided on the lower end surface of the top of the plastic lead sealing cap 8, and a forced removal groove 28 is provided on the upper end surface of the top of the plastic lead sealing cap 8 at a position corresponding to the groove 27. By providing the groove 27 and the forced removal groove 28, the plastic lead sealing cap 8 forms a weak point at this position, making it easier for tools such as a screwdriver to be inserted to remove the plastic lead sealing cap 8.

[0024] Preferably, the second flip cover 5 is provided with a guide groove 29 which smoothly transitions with the second lead sealing hole 16 of the second screw 15, so as to facilitate the passage of the lead sealing wire.

[0025] As mentioned above, this does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
