[0003] Current technology uses electricity meters to measure the electricity used by users. Most of these meters are installed in metering boxes. The locking mechanism of existing metering boxes is too simple, using only simple latches. The boxes are also too rudimentary, making them easy to damage and expose the electricity meters inside.

[0035] The bottom of the 1107 connector has a hexagonal groove.

[0036] like Figure 9As shown, the dehumidification system includes a guide pipe 1201, a baffle plate 1202, an air extraction assembly 1203, a drying element 1204, and a dust filter 1205. Two symmetrical guide pipes 1201 are bolted to the bottom of the main housing 1. A dust filter 1205 is fixedly attached to the upper side of the interior of each of the two guide pipes 1201. A baffle plate 1202 is fixedly attached to the bottom of each of the two guide pipes 1201. An air extraction assembly 1203 is connected to the lower side of the interior of each of the two guide pipes 1201. A drying element 1204 is fixedly attached to the interior of each of the two guide pipes 1201, and the drying element 1204 is located between the air extraction assembly 1203 and the dust filter 1205.

[0037] The drying component 1204 is a spiral plate, and the plate surface is covered with a water-absorbing material.

[0038] It also includes a rain cover 2; the main body 1 is fixedly connected to the upper part of the rain cover 2 for blocking rainwater.

[0039] It also includes an alarm light 3, a first pressure-bearing component 4, and a second pressure-bearing component 902; two alarm lights 3 for emitting light and sound are fixedly attached to the upper surface of the main body 1; a first pressure-bearing component 4 is fixedly attached to the middle of the left side and the middle of the right side of the main body 1, and the first pressure-bearing component 4 is composed of a pressure sensor and a spring; a second pressure-bearing component 902 is fixedly attached to the middle of the front surface of the door 901, and the second pressure-bearing component 902 is composed of a pressure sensor and a spring.

[0040] Before using the anti-theft meter box with self-protection function (hereinafter referred to as the anti-theft meter box), the main box 1 is installed and fixed to the wall with bolts. Then, the rain cover 2 is installed on the top of the main box 1. In rainy weather, the rain cover 2 can divert rainwater downwards at an angle to prevent water from entering the anti-theft meter box. After that, all components are installed and debugged. After the debugging is completed, the anti-theft meter box is put into use and equipped with an intelligent unlocking system.

[0041] During routine installation of new electricity meters, the installer uses a hexagonal rocker arm to unlock the meter. Then, using the intelligent unlocking system, the installer operates the electric push rod 1102 in the locking system. The electric push rod 1102 moves the U-shaped frame 1103 downwards. At this time, the first spur gear 1104 follows the U-shaped frame 1103 downwards, so the second spur gear 1112 only meshes with the third spur gear 1114. The installer then inserts the hexagonal rocker arm into the coupling 1107 and manually cranks the rocker arm. This causes the connecting rod 1106 to rotate, which in turn drives the first bevel gear 1108 to drive the second bevel gear 1111. The second bevel gear 1111 drives the first rotating shaft 1110 to rotate, which in turn drives the second spur gear 1112 to drive the third spur gear 1114. The third spur gear 1114... While the second rotating shaft 1113 rotates, it moves the transmission plate 1118 upward. At this time, the transmission plate 1118 pushes the third spring telescopic component 1116 to retract. Simultaneously, the transmission plate 1118 drives the two fastening bolts 1117 to move upward. Then, the operator can no longer rotate the hexagonal crank. The two fastening bolts 1117 move upward and disengage from the two locking pieces 904 respectively. Therefore, the two locking pieces 904 are no longer restrained. Then, the operator pulls the handle 903. Utilizing the rotational characteristics of the two connecting pieces 8, the operator can open the box door 901 and then install the electricity meter to be installed in the designated mounting slot 13. Before obtaining the permission to open the box door 901, the operator must obtain the operating permission of the electric push rod 1102. Relying solely on the operation of the hexagonal crank, it is impossible to achieve the simultaneous rotation of the three meshing gears, thus completing the protection against electricity theft and achieving self-protection.

[0042] When faced with malicious damage, criminals may forcibly drag or strike the main housing 1. Therefore, when faced with such an impact, taking the first buffer plates 502 on both sides as an example, the criminals may use tools to forcefully strike the first buffer plates 502. At this time, the first buffer plates 502 push inwards against the six first spring telescopic members 501, which buffer most of the impact force, reducing the damage to the main housing 1. Simultaneously, as the first buffer plates 502 push inwards, they compress the first pressure-bearing component 4, causing the pressure reading on the first pressure-bearing component 4 to increase rapidly. After multiple changes in the pressure reading, the intelligent unlocking system can determine that there has been malicious damage. At this time, the power switch 6 is closed, causing a power outage in the user's home. Simultaneously, the two alarm lights 3 are activated, emitting an alarm. The system alerts the surrounding crowd to intimidate and apprehend criminals. Similarly, when criminals maliciously pull on the first buffer plate 502, the pressure reading on the first pressure-bearing component 4 decreases sharply, but exceeds the range that the six first spring extension components 501 can withstand, triggering the two alarm lights 3. The second buffer plate 102 on the door 901 operates in the same way, and the second buffer plate 102 relies on the second pressure-bearing component 902 for pressure sensing and monitoring to achieve self-protection. When the alarm fails, the readings on the first pressure-bearing component 4 and the second pressure-bearing component 902 stop changing, indicating damage. At this time, the intelligent unlocking system automatically controls the main power switch 7 to cut off the power in the enclosed space, preventing criminals from opening the power switch 6 and thus preventing electricity theft.

[0043] During normal times, especially during the rainy season, there is a lot of moisture inside the metering box. To improve the safety of the meter, existing metering boxes do not pay attention to drying, resulting in a large amount of moisture inside the metering box, which seriously affects the safety of the meter. The drying element 1204 at the bottom of the main box 1 isolates the humid air at the bottom. Because the drying element 1204 is spiral-shaped, it increases the contact between the humid air and the drying element 1204, preventing the humid air at the bottom from entering the main box 1. The desiccant on the surface of the drying element 1204 can effectively adsorb water molecules in the air to achieve drying. The air extraction component 1203 is operated periodically. The air extraction component 1203 draws air from inside the main box 1 to circulate. The continuous air circulation inside the main box 1 can cool the meter. At the same time, the dust filter 1205 can adsorb dust particles. While cooling, it can also remove dust, preventing a large amount of dust from adhering to the surface of the meter and affecting its performance.
