The top ends of the slide rods 6 are in contact connection with the bottom walls of the side baffles 3. The bottom ends of the side baffles 3 are located below the heat dissipation grooves 2. When the utility model is in use, the slide rods 6 are inserted into the slide holes 8 and are slidably connected with the ridges 5. The inserting rods 7 are inserted into the insertion slots A9 and are fixedly connected with the slide rods 6, so that the bottom ends of the slide rods 6 and the inserting rods 7 are respectively in contact connection with the bottom walls of the slide holes 8 and the insertion slots A9. The side baffles 3 are rotatably arranged on the box body 1. The side baffles 3 will press on the slide rods 6, so that the top ends of the slide rods 6 are in contact connection with the bottom walls of the side baffles 3 to support and fix the side baffles 3. At this time, the side baffles 3 will be inclined. The side baffles 3 are located on the side of the heat dissipation grooves 2 away from the box body 1. The bottom ends of the side baffles 3 are located below the heat dissipation grooves 2. When there is a heavy rain or a windy and rainy day, the rainwater will fall on the side baffles 3 and slide down along the side baffles 3, playing a role in preventing the rainwater from entering the inside of the box body 1 through the heat dissipation grooves 2; The nut 15 is screwed onto the stud 14 and is in threaded connection with the stud 14. The canopy 4 is placed above the box body 1 and the stud 14 is inserted into the through hole 16, so that the canopy 4 presses on the nut 15 and is in contact connection with it. The canopy 4 is a triangular canopy. When there is a heavy rain or a windy and rainy day, the rainwater will fall on the canopy 4 and slide down along the canopy 4, playing a role in preventing the rainwater from entering the inside of the box body 1 through the gap between the box door and the box body 1; In summary, the utility model has strong waterproofness, has the beneficial effect of preventing rainwater from entering the inside of the box body 1, solves the problem that the waterproofness of the existing electric energy metering box is relatively general. When there is a heavy rain or a windy and rainy day, the rainwater easily enters the inside of the box body 1 from the heat dissipation window and the connection part between the box door and the box body 1, resulting in the electronic instruments inside the box body 1 being affected by moisture or water ingress, and causing damage to the electronic instruments.
[0021] Preferably, a ventilation component is provided on the box body 1. The ventilation component includes a fan A 11 and a fan B 12.
