There are also connections between the first door 6 and the first enclosure 1, and between the second door 14 and the third door 15 and the second enclosure 2. A fourth anti-theft structure is provided. The main control room 3, which houses the first electricity meter 4 and the power switch 5, is located on the first casing 1. The metering room 10, which houses the second electricity meter 12, and the load switch 13, and the outgoing line room 11, which are separated by a partition 8, are located on the second casing 2. This structural design improves the cleanliness of the meter box's interior. Furthermore, the meter box adopts a split structure, with the first casing 1 and the second casing 2 assembled together, facilitating production and transportation. Different specifications of the first casing 1 and the second casing 2 can be produced during production, and they can be combined and assembled according to customer needs to meet diverse usage requirements. This is achieved through the setting of the first door 6 and the first flip cover 7, the... The installation of the second door 14 and the second flip cover 16, as well as the third door 15 and the third flip cover 17, prevents external moisture and dust from easily penetrating the interior of the first housing 1 and the second housing 2, ensuring the safety of electrical components. Furthermore, by installing a first anti-theft structure between the first door 6 and the first flip cover 7, a second anti-theft structure between the second door 14 and the second flip cover 16, and a third anti-theft structure between the third door 15 and the third flip cover 17, and by installing a fourth anti-theft structure between the first door 6 and the first housing 1, and between the second door 14 and the third door 15 and the second housing 2, the meter box has excellent anti-theft performance, a reasonable structural design, and high safety in use.

[0042] In this embodiment, first positioning recesses 18 are provided at corresponding positions on the first housing 1 and the second housing 2. It should be noted that the first positioning recesses 18 on the first housing 1 are located on the left inner wall and there are multiple of them, while the first positioning recesses 18 on the second housing 2 are located on the right inner wall. The first positioning recesses 18 on the second housing 2 are respectively provided for the metering chamber 10 and the cable outlet chamber 11. A hinge 19 is screwed into the first positioning recess 18. Fixing ears are formed on both sides of the bottom of the hinge 19, and a hinge that cooperates with the hinge shaft is formed on the top front end of the hinge 19. The hinge notch 20 can be an arc-shaped notch. The first positioning recess 18 provides installation positioning for the screw-fixed hinge 19, thereby achieving stable and rapid installation. By using the hinge notch 20 in conjunction with the hinge shaft, the first door 6 and the first shell 1, the second door 14 and the third door 15 and the second shell 2 can be quickly assembled. Furthermore, the hinge 19 adopts a split structure with the first shell 1 and the second shell 2, which avoids excessive hinge stress on the first shell 1 and the second shell 2, resulting in a longer product service life and a reasonable structural design.

[0043] In this embodiment, the hinge notch 20 can be a U-shaped notch. In the above structure, the hinge member 19 is also provided with a mounting cavity 21 with openings at the bottom and front. The mounting cavity 21 is connected to the hinge notch 20 and has a sliding limiting plate 22 inside. A locking structure is also provided between the limiting plate 22 and the mounting cavity 21 to prevent the limiting plate 22 from moving downward. The bottom opening allows the limiting plate 22 to be inserted into the mounting cavity 21. The front opening is mainly used to release the locking between the limiting plate 22 and the mounting cavity 21 by means of a tool. When the limiting plate 22 is locked with the mounting cavity 21, the top of the limiting plate 22 forms a limiting position on the hinge axis within the hinge notch 20. The mounting of the first box door 6 with the first box shell 1, the second box door 14 and the third box door 15 with the second box shell 2 is also described. When the locking of the limiting plate 22 and the mounting cavity 21 is released, the limiting plate 22 moves down a certain distance (the top of the limiting plate 22 moves down to outside the hinge notch 20). After the hinge shafts on the first door 6, the second door 14 and the third door 15 are placed at the bottom of the hinge notch 20, the limiting plate 22 moves up until the locking structure forms a locking. The top of the limiting plate 22 will limit the hinge shaft, thereby preventing the first door 6, the second door 14 and the third door 15 from disengaging during rotation. Therefore, by setting the hinge notch 20 as a U-shaped notch and cooperating with the limiting plate 22, the connection stability between the first door 6 and the first shell 1, the second door 14 and the third door 15 and the second shell 2 will be better, and the structural design will be reasonable.

[0044] In this embodiment, the locking structure includes a latch 23 and an elastic hook 24. The latch 23 is formed on the rear inner wall of the mounting cavity 21, and the elastic hook 24 is formed on the limiting plate 22. The hook part of the elastic hook 22 is also set as an arc-shaped structure. By using the cooperation of the latch 23 and the elastic hook 24, and setting the hook part of the elastic hook 24 as an arc-shaped structure, the operation will be convenient when the limiting plate 22 is unlocked from the mounting cavity 21. There are also mutually cooperating positioning slots 25 and positioning pins 26 between the two side walls of the mounting cavity 21 and the limiting plate 22. The positioning slots 25 are formed on the two side walls of the mounting cavity 21 and are through the bottom. The positioning pins 26 are formed on the two side walls of the limiting plate 22. By setting the corresponding positioning slots 25 and positioning pins 26, the limiting plate 22 will not fall out, the installation is more stable, and the movement is smoother.

Furthermore, setting the bottom wall of the heat dissipation groove 48 as a guide slope makes it difficult for external rainwater to enter through the heat dissipation port 49. In addition to achieving heat dissipation, it also has a certain waterproof function.

[0051] In this embodiment, a first waterproof flange 50 is provided on the outer side of the first flip cover 7 on the first door 6, and a second waterproof flange 51 is also provided on the outer side of the window in the first mounting recess of the first door 6. The arrangement of the first waterproof flange 50 and the second waterproof flange 51 can guide the flow of light rainwater. When the first flip cover 7 is opened, rainwater is less likely to invade the interior from the first mounting recess on the first door 6, making it safer to use.

[0052] In this embodiment, a pre-drilled screw fixing hole 52 is provided on the wall of the main control room 3 at the power switch 5. By setting the pre-drilled screw fixing hole 52, more components can be fixed.

[0053] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
