[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1-5 An easy-to-maintain electricity metering box includes a box body 1. The bottom of the inner cavity of the box body 1 is connected to guide rails 8 by bolts near the front and rear sides. Inverted U-shaped blocks 21 are slidably connected to the guide rails 8 near the right side. The tops of the two inverted U-shaped blocks 21 are connected to the same mounting plate 14 by bolts. Mounting holes 12 are opened near the four corners of the top of the mounting plate 14. The right side of the box body 1 is slidably connected to an opening and closing plate 6, and a transparent observation window 7 is installed near the top of the right side of the opening and closing plate 6. In the above technical solution, a rack plate 9 is bolted to the left side of the opening plate 6 near the bottom along the front and back direction. A first gear 10 is engaged on the left side of the rack plate 9. The two first gears 10 are movably connected to the inner wall of the box 1 through a rotating shaft and a bearing. Several evenly distributed tooth blocks 15 are bolted to the top of the mounting plate 14 near the front and back sides. The top of the two sets of tooth blocks 15 are engaged with a second gear 13. The two second gears 13 are movably connected to the inner walls of the front and back sides of the box 1 through a rotating shaft and a bearing. A conveyor belt 11 is connected between the first gear 10 and the second gear 13 through a pulley drive. The bottom of the box 1 is bolted to the bottom plate 4. A stabilizing hole 2 is opened at the top of the bottom plate 4 near the four corners. The above technical solution enables the mounting plate 14 to move out of or into the housing 1 while the opening and closing plate is being driven to open and close, thereby enabling convenient installation and maintenance and improving its installation and maintenance efficiency.

[0019] Working Principle: In use, this technical solution first pulls the opening / closing plate 6 upwards, causing the insertion hole 17 to disengage from the insertion post 16. The opening / closing plate 6 then rotates the first gear 10 via the rack plate 9. The first gear 10 drives the second gear 13 via the conveyor belt 11. The second gear 13 then moves the gear block 15, causing the mounting plate 14 to move forward. When the opening / closing plate 6 moves to the top, the first electromagnet 5 and the second electromagnet 22 attract each other. At this time, the electrometer is installed on the top of the mounting plate 14 through the mounting hole 12. Subsequently, the power to the first electromagnet 5 and the second electromagnet 22 is cut off, causing the opening / closing plate 6 to slide downwards. The opening / closing plate 6 then rotates the first gear 10 via the rack plate 9. The first gear 10 drives the second gear 13 via the conveyor belt 11. The second gear 13 then moves the gear block 15, causing the mounting plate 14 to move backwards. This allows the mounting plate 14 to move out of or into the housing 1 while simultaneously opening and closing the opening / closing plate, thus enabling convenient installation and maintenance, improving installation and maintenance efficiency.

[0020] Example 2 Please see Figure 1-5 The left side of the opening and closing plate 6 is connected to the bottom of the front and back direction by bolts. The right side of the box body 1 is connected to the top of the front and back direction by bolts. The top of the bottom plate 4 is connected to several evenly distributed plug posts 16 by bolts. The bottom of the opening and closing plate 6 is provided with plug holes 17 that match the plug posts 16, which can effectively fix the position of the opening and closing plate 6. The left side of the housing 1 has several evenly distributed ventilation holes 3. The front and rear sides of the housing 1 near the top are respectively provided with ventilation windows 19, and dustproof nets 20 are bolted into the ventilation windows 19. The left side of the opening plate 6 is respectively bolted to the front and rear sides and sliding plates 23 are respectively bolted to the left side of the opening plate 6. The right side of the housing 1 is respectively provided with sliding grooves 18 that match the sliding plates 23 near the front and rear sides, so that it can effectively ventilate and dissipate heat, thereby enabling effective air circulation and improving its ventilation efficiency.
