[0002] In the field of electricity metering, the safety and ease of installation and maintenance of electricity meters are crucial metering devices. The casing of the electricity meter's terminals is an important component that protects the internal electrical components and prevents external interference and unauthorized operation.

[0003] Currently, most electricity meter terminals on the market are fastened with bolts. Each time the casing is installed or removed, maintenance personnel must use specific wrenches or screwdrivers to tighten or loosen multiple bolts, which greatly reduces work efficiency and increases labor and time costs. At the same time, the threads are prone to wear due to corrosion or repeated installation and removal. Once the threads are stripped or rusted, the casing will be difficult or even impossible to remove normally. Furthermore, the bolts are directly exposed on the surface of the casing, and anyone with ordinary tools can easily open the casing. Utility Model Content

[0004] In view of the fact that the existing installation methods mentioned above can no longer meet the requirements of modern smart grids in terms of convenience, reliability and security, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an easy-to-assemble electricity meter housing, the purpose of which is that the lock is completely built-in and hidden inside the housing, and there are no traditional physical disassembly points such as bolt heads and screw holes when viewed from the outside.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an easy-to-assemble electricity meter housing, including a bottom shell with a battery cavity and a wiring cavity, a top cover detachably installed on the front end face of the bottom shell by bolts, a battery cover detachably installed on the battery cavity of the bottom shell, and a wiring end cover detachably installed on the wiring cavity of the bottom shell.

[0030] Decorative bolts 14 are rotatably installed on both sides of the outer wall of the battery cover 4 and the terminal cover 5. The decorative bolts 14 are set to disguise and confuse, so that those who do not know the situation will think that the decorative bolts 14 are loose or damaged and cannot be opened normally, and give up.

[0031] The dual-head lock 3 includes a servo motor 31 installed inside the top cover 2, and two L-shaped slide plates 34 slidably installed on both sides of the servo motor 31. The power meter supplies power to the servo motor 31 while connected to the mains power. The battery in the battery compartment serves as a backup power source for the servo motor 31. The L-shaped slide plates 34 are located on the outer wall of the top cover 2. The dual-head lock 3 also includes a Bluetooth switch and a Bluetooth controller. The Bluetooth controller is installed inside the bottom shell 1. Bluetooth control is a mature existing technology, so it will not be described in detail. The output shaft of the servo motor 31 is located outside the top cover 2 and is fixedly connected to a rotating disk 32. A push-pull strip 33 is rotatably installed between one end of the rotating disk 32 near the L-shaped slide plate 34 and one side of the L-shaped slide plate 34.

[0032] Weight reduction holes are provided at the lateral end of the L-shaped slide plate 34 and the middle of the push-pull strip 33. Two sets of protrusions are installed at the lateral end of the L-shaped slide plate 34, and the plum blossom block 15 is fixed on the outside of the protrusions.

[0033] The L-shaped slide plate 34 has grooves 36 at both the upper and lower ends of the end face away from the plum blossom block 15. The L-shaped slide plate 34 is slidably connected to the guide rail 35 through the grooves 36, and the guide rail 35 is fixed to the outer wall of the top cover 2.

[0034] The L-shaped slide plate 34 has a first rotating shaft mounted on one end near the rotating disk 32. The rotating disk 32 has two second rotating shafts mounted symmetrically on the end away from the servo motor 31. The push-pull bar 33 is rotatably mounted between the first and second rotating shafts.

[0035] During use, the double-headed lock 3 is completely built-in and hidden inside the terminal cover 5 through the built-in self-locking lock and the external non-disassembly interface, eliminating the possibility of illegal opening using conventional tools, effectively preventing electricity theft and human vandalism, and greatly improving the anti-theft and overall security level of the electricity meter. At the same time, it abandons the bolt structure that is prone to rust and stripping, avoiding the problem of being unable to disassemble due to mechanical thread wear or rust. Furthermore, it simplifies the operation process, realizes one-button opening and closing, greatly improves the efficiency of installation, disassembly and maintenance, and reduces labor intensity.

[0036] Example 2

[0037] Reference Figures 1-2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a plate cavity 7 is provided on the upper side of the middle of the end face of the bottom shell 1 away from the top cover 2. A hanging plate 8 is detachably installed inside the plate cavity 7. A hanging hole 11 is provided at the top of the hanging plate 8. A dovetail mounting groove 6 is provided on the end face of the bottom shell 1 away from the top cover 2 and below the hanging plate 8.

[0038] The interior of the plate cavity 7 is equipped with several internal threaded sleeves 9 arranged longitudinally. Locking bolts 10 are threadedly installed on the internal threaded sleeves 9 through their threaded holes. The suspension plate 8 is provided with fixing holes for the locking bolts 10 to pass through. The number of fixing holes is the same as the number of internal threaded sleeves 9. The suspension plate 8 is detachably installed inside the plate cavity 7 through the threaded connection between the locking bolts 10 and the internal threaded sleeves 9. When the suspension plate 8 is not needed, it can be disassembled and stored, and can be added for use as needed.

[0039] During use, a dovetail mounting groove 6 and a detachable mounting plate 8 are provided on the back of the bottom shell 1, so that the electricity meter can be installed in two ways: rail mounting and wall mounting. It supports two modes of fixed structure, which facilitates the fixed installation of the electricity meter and adapts to a variety of installation environments.

[0040] The remaining structure is the same as that in Example 1.

[0041] Based on embodiments 1-2, the working principle of this utility model is as follows: When the terminal cover 5 is installed in the wiring cavity and the battery cover 4 is installed in the battery cavity, the Bluetooth-controlled servo motor 31 drives the rotating disk 32 to rotate clockwise, driving the push-pull strips 33 on both sides to move to both sides respectively. Under the linkage of the push-pull strips 33 on both sides, the guide rail 35 is pushed to move to the side, and the plum blossom card block 15 enters the plum blossom card hole 13 for locking, thus completing the fixation between it and the bottom shell 1.

[0042] Conversely, the servo motor 31 is driven to rotate counterclockwise, pulling the plum blossom card block 15 out of the plum blossom card hole 13 to complete the disassembly.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
