[0015] (2) This invention seals the sliding door by making the sealing ring contact with the sliding door on all sides, thereby preventing rainwater from entering the meter box body through the gap in the sliding door. Moisture may damage the electronic components inside the meter box body, affecting the normal use of the equipment. At the same time, the movement of the sealing ring toward the sliding door will drive the trapezoidal pull rod toward the sliding door. The movement of the trapezoidal pull rod toward the sliding door will push the sliding rod upward. The upward movement of the sliding rod will drive the dehumidification plate upward. The upward movement of the dehumidification plate cooperates with the heat dissipation groove to push down the impurities adhering to the dehumidification plate, thereby preventing the impurities from adhering and affecting the dehumidification effect of the dehumidification plate.

[0016] (3) This invention opens the bottom of the meter box body by rotating the rotating plate downward, thereby preventing the accumulation of dust, corrosion or water inside the meter box that has not been cleaned or maintained for a long time, which may affect electrical contact and even cause electrical failure. At the same time, opening the bottom of the meter box body can directly discharge impurities without manual cleaning, thereby improving work efficiency. At the same time, the rotating plate will drive the sliding long plate to rotate downward during the downward rotation of the rotating plate. The sliding long plate will be pulled by the hinged rod when it rotates downward. The hinged rod will pull the sliding long plate to slide downward along the rotating plate, and the impurities on the rotating plate will be pushed away by the sliding long plate, thereby preventing the impurities from adhering to the rotating plate and improving the cleaning effect.
