[0002] In power systems, electricity meters are typically installed at the user end to track electricity consumption. These meters require corresponding electricity metering boxes for use. The metering box is a housing and control unit for the electricity meter. It is an important piece of equipment used in power supply and distribution systems, serving as the electrical equipment that receives and distributes electrical energy. It is a crucial component of the power transmission and distribution industry and is widely used in various locations, such as high-rise buildings, residential communities, industrial and mining enterprises, and construction sites.

[0003] However, existing electricity metering boxes still have the following defects in use: the box door is locked by a locking assembly that works with the box body. The existing locking assembly includes a rotating shaft and a locking plate. The rotating shaft drives the locking plate to rotate, and the locking plate locks the box door by making misaligned contact with the box body. Under long-term and frequent use, the structure described above is prone to deformation between the box body and the box door, making it impossible to lock and causing the box door to be unable to close, thus affecting the normal use of the electricity metering box. Summary of the Invention

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-3 This is a schematic diagram of the structure of an energy metering box according to a preferred embodiment of the present invention. In this embodiment, an energy metering box, such as... Figures 1 to 3 As shown, the enclosure includes a housing 1 and a door 2 connected by hinges. The housing 1 has an internal mounting cavity 11, and the door 2 has a mounting hole 21. A lock body assembly 3 is fixedly installed within the mounting hole 21, and a mounting block 4 is fixedly connected to the inner wall of the mounting cavity 11 at a position corresponding to the lock body assembly 3. The lock body assembly 3 includes a mounting base 31, a rotating core 32, and a locking plate 33. The mounting base 31 is fitted into the mounting hole 21; the rotating core 32 is rotatably connected to the interior of the mounting base 31; the end of the rotating core 32 extends to the inner side of the housing 1 and is fixedly installed with the locking plate 33. The locking plate 33 movably abuts against the surface of the mounting block 4. Specifically, when the rotating core 32 is rotated using a special key or tool, the locking plate 33 moves accordingly and engages or disengages from the mounting block 4, thus achieving the function of locking or unlocking the door 2.

[0024] In this embodiment, as Figure 3 As shown, a washer 35 is fitted onto the surface of the rotating core 32, and the washer 35 is located between the locking plate 33 and the rear end face of the mounting base 31. The end of the rotating core 32 has an external thread, and the locking plate 33 is tightened and fixed by a nut 34 to prevent the locking plate 33 from loosening axially. The washer 35 reduces the frictional resistance when the locking plate 33 rotates.

[0025] In this embodiment, as Figure 3As shown, a card interface 331 is provided on the surface of the locking plate 33, and a card receiving position 41 matching the card interface 331 is provided on the top of the mounting block 4. When the door 2 is closed, the card interface 331 is embedded in the card receiving position 41, and the inner surfaces of the two are in close contact to form a mechanical interlock. The depth of the card receiving position 41 is greater than the height of the card interface 331 to ensure locking stability.

[0026] In this embodiment, as Figure 3 As shown, mounting block 4 has fixing holes 42 on its surface. Bolts are used to fasten mounting block 4 to the inner wall of mounting cavity 11 by passing through fixing holes 42. The fixing holes 42 are countersunk holes to prevent the bolts from protruding and interfering with the movement of locking plate 33.

[0027] In this embodiment, as Figure 3 As shown, a connector 321 is provided at the front end of the rotating core 32 for transmitting torque in conjunction with a special key or tool. The inner wall of the connector 321 is provided with anti-slip texture to enhance transmission reliability.

[0028] In this embodiment, as Figure 3 As shown, the locking plate 33 adopts a Z-shaped structure, with its front end vertically connected to the rotating core 32, its middle section bent and extended, and its end forming a horizontal locking portion. The locking interface 331 is opened in the horizontal locking portion. The Z-shaped structure allows the locking plate 33 to avoid the internal components of the housing 1 and extends the lever arm to increase the locking torque.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
