[0051] In this utility model, the design based on the above structure is realized;

[0052] 1. Double-door design: The outer doors (left and right) are made of high-strength, weather-resistant stainless steel, providing excellent rigidity and impact resistance. The outer door surface features a unique brushed finish and a drainage structure, allowing rainwater to drain quickly away, preventing water accumulation or seepage into the box. High-quality rubber sealing strips are installed along the edges of the outer doors to ensure a tight seal with the electrical box body, effectively preventing rainwater and dust intrusion.

[0053] The inner door is made of metal, such as galvanized steel, providing strong anti-theft performance. The interior of the inner door is filled with insulation materials, such as polyurethane foam and asbestos, effectively preventing the transfer of external heat and maintaining a stable internal temperature. A sophisticated locking system is installed on the inner door, featuring anti-pry and anti-theft functions. It can only be opened with a special key or authorized electronic password, greatly enhancing the security of the metering box.

[0054] 2. Structural Connection and Layout: The outer and inner doors are connected by concealed hinges installed on the inside of the doors. This not only makes opening and closing the doors smoother but also ensures a clean and aesthetically pleasing appearance. When the doors are closed, an air buffer layer is formed between the outer and inner doors, further enhancing heat and sound insulation.

[0055] The double-layered door is sealed to the main body of the electrical box using a sealing gasket, ensuring good sealing performance under various environmental conditions. The interior of the box features a dedicated meter mounting frame, with each meter position independent of the others, facilitating the installation, maintenance, and management of the electricity meters. Additionally, the box includes wiring channels and wire harness securing devices, ensuring a neat and orderly wiring layout and preventing clutter and interference.

[0056] The working principle of this utility model is:

[0057] Protection principle: The outer doors (left and right doors) are made of high-strength, corrosion-resistant stainless steel plates, and the specially made EPDM rubber sealing strips installed on their edges have good elasticity and sealing performance.

[0058] When the outer door is closed, the sealing strip fits tightly against the cabinet, forming the first line of defense against water damage and effectively preventing rainwater from seeping in through the door gaps. In addition to blocking rainwater, the sealing strip also effectively prevents dust from entering. Its tight fit makes it difficult for dust to get into the cabinet through the door gaps.

[0059] Insulation Principle: The double-layered hollow structure of the outer door is a key design element for insulation. The polyurethane foam, asbestos, and other insulation materials filling the space have low thermal conductivity, effectively preventing heat transfer. In outdoor environments, when the outside temperature is high or low, the double-layered hollow structure and insulation materials of the outer door slow down the rate at which heat is transferred into or out of the enclosure, keeping the internal temperature relatively stable. While the inner door primarily serves a security function, it also buffers heat transfer to some extent. The air layer formed between the inner and outer doors further enhances the insulation effect, reducing the impact of external temperature changes on electrical components such as the power meter inside the enclosure, ensuring they operate in a suitable temperature environment, and improving the stability and lifespan of the equipment.

[0060] Anti-theft principle: The outer door, as the first line of defense, uses high-strength stainless steel and excellent sealing performance to effectively prevent unauthorized intrusion. The presence of the outer door increases the difficulty and time cost of illegally opening the meter box. The inner door is made of high-quality galvanized steel, possessing high strength and resistance to damage. The crisscrossing reinforcing ribs inside the inner door further enhance its overall strength, making it difficult for external forces to damage the inner door structure.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
