[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] In order to solve the problems of poor waterproof performance of the electric energy metering box and possible interference with maintenance operations after the box door is opened in the prior art, the following technical solutions are given. Please refer to Figures 1-10 ;

[0030] An electric energy metering box with a waterproof structure includes a box body 1. An opening 2 is provided on one side of the box body 1. A box door 3 is pivotally connected to the inner top of the opening 2. A waterproof edge 4 is provided inside the box body 1 near the opening 2. There are three waterproof edges 4 in total, which are respectively located on both sides and the inner bottom of the box body 1. The waterproof edges 4 are connected to each other. The waterproof edge 4 is in contact with the inner side wall of the box door 3. A sealing pad is provided on the surface of the waterproof edge 4 facing the box door 3. When the box door 3 is completely closed, the inner side wall of the box door 3 is in contact with the waterproof edge 4. The sealing pad is provided to prevent gaps between the box door 3 and the waterproof edge 4.

[0031] On both ends of the box body 1 facing the box door 3, there are vertical border strips 10. The setting of the border strips 10 can enhance the structural strength of the box door 3 and prevent deformation during use. On one side of the top of the border strip 10 facing the chute 12, there is a groove 11, and the groove 11 communicates with the chute 12. On both sides of the top of the box door 3, there are rotating shafts 8. The rotating shafts 8 penetrate into the groove 11 and can rotate therein. On the top surface of the box door 3, there is a soft rubber layer 9. When the box door 3 is closed, the soft rubber layer 9 can contact and seal with the inner top surface of the box body 1 to prevent rainwater from seeping in.

[0032] On both sides of the inner top of the box body 1, there is a support strip 5 fixed respectively. A chute 12 for the box door 3 to slide is formed between the support strip 5 and the inner top surface of the box body 1. When opening the box door 3, with the rotating shaft 8 as the axis, the box door 3 is flipped obliquely upward on the outside. The rotating shaft 8 rotates in the groove 11 until the box door 3 is opened to the horizontal state. At this time, the box door 3 is pushed towards the inside of the box body 1, and the rotating shaft 8 is correspondingly pushed into the chute 12 from the groove 11. Both ends of the box door 3 slide on the upper surface of the support strip 5 and move along the extending direction of the chute 12 until the box door 3 is pushed into the box body 1, so that the opening 2 can be completely opened, providing an open operation space and vision for the staff. It is not only convenient to open and close, but also the box door 3 is sufficiently fixed and limited after being opened, and will not produce flipping or displacement to interfere with the operation of the staff inside the box body 1. When closing the box door 3, pull out the box door 3 until both sides of the box door 3 are separated from the chute 12 and the rotating shaft 8 is pulled back into the groove 11. At this time, put down the box door 3, and the box door 3 rotates downward around the rotating shaft 8 until the inner side of the box door 3 abuts against the waterproof edge 4 to achieve closure.

[0033] On two opposite sides of the box body 1, there are ventilation holes 6. Outside the ventilation holes 6, there is a covering hood 7. The ventilation holes 6 are symmetrically arranged at the top and bottom of the side of the box body 1. The covering hood 7 is fixed outside the box body 1 and covers the ventilation holes 6. The opening of the covering hood 7 faces downward, ensuring that the ventilation holes 6 are not invaded by rainwater without being blocked, thus improving the waterproof property of the box body 1. When the temperature inside the box body 1 is too high, the hot air rises and can be discharged through the ventilation holes 6 at the upper part of the box body 1. The low air pressure in the box body 1 causes the cold air outside to enter through the ventilation holes 6 at the bottom of the box body 1, so that air circulation can be realized inside the box body 1, effectively evacuating the heat generated by the equipment inside the box body 1.

[0034] There is an observation window 14 on the box door 3. Through the observation window 14, the staff can still observe the operation of the equipment inside the box body 1 without opening the box. At the corresponding positions of the bottom of the box door 3 and the box body 1, there is a lock catch 13. When the box door 3 is flipped down and closed, it can be locked in the lock catch 13 to lock the box door 3 and the box body 1, providing safe protection for the equipment.

[0035] At both the upper and lower ends of the mounting surface of the box body 1, there are provided lifting lugs 15. At the exact middle position of the mounting surface, there is also provided a resisting plate 16. The contact surfaces of the resisting plate 16 and the lifting lugs 15 with the wall are all located on the same vertical plane. The box body 1 is installed on the wall through the lifting lugs 15. The resisting plate 16 and the lifting lugs 15 extend a certain distance outward from the box body 1, which can separate the back plate of the box body 1 from the wall surface by a certain distance. This can not only prevent rainwater from remaining between the back plate and the wall surface and causing erosion to the back plate, but also enable the device to dissipate heat through the back plate, increasing the heat dissipation surface of the device.
