Moreover, the heat generated at different positions inside is different. The low efficiency of natural heat dissipation leads to reduced overall safety. Secondly, the box does not have good impact resistance, cannot protect internal components, and cannot adapt to a variety of usage environments.

[0006] Therefore, a three-phase multi-meter electric energy metering box is designed to optimize the above problems. Utility Model Content

[0026] To make the technical solutions of the present invention clearer and more definite to those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.

[0027] As Figure 1-Figure 5 shown, this embodiment provides a three-phase multi-metering position electric energy metering box, including a box body 1. Protective blocks are provided at the top and bottom of the box body 1, and cavities are provided inside the protective blocks. The protective blocks with cavities can protect the top and bottom corners of the box body 1, improving the protection force. A sealed door panel 2 is installed on one side of the box body 1. A heat exchange cover 3 is installed through the sealed door panel 2. A refrigeration sheet 4 is installed on the outside of the heat exchange cover 3. A fan 5 is fixedly installed on one side of the heat exchange cover 3. A telescopic hose 22 is fixed on the other side of the heat exchange cover 3. A connecting pipe 23 is fixed at the bottom end of the telescopic hose 22. A sleeve 6 communicated with the connecting pipe 23 is fixed at the bottom end of the connecting pipe 23. First through holes 7 are evenly opened on one side of the sleeve 6. Movable pipes 8 are slidably installed inside both ends of the sleeve 6. A sealing gasket is sleeved on the outside of the movable pipe 8, and the sealing gasket is a rubber sealing gasket. The setting of the rubber sealing gasket increases the sealing performance with the sleeve 6, making the cold air more targeted to be sent out from the holes. Second through holes 9 horizontally aligned with the first through holes 7 are evenly opened on the movable pipes 8. A slide block 10 is fixed on the other side of the sleeve 6, and the slide block 10 is slidably connected with the outside of the sealed door panel 2. An adjusting rod 11 is threadedly connected inside the slide block 10, and both ends of the adjusting rod 11 are rotatably installed on one side of the sealed door panel 2 through rotating pipes. A wire passing port 21 is opened at the bottom of the box body 1.

[0028] Specifically, rotate the adjusting rod 11 to move the slide block 10 up and down, thereby driving the sleeve 6 up and down to be at the same height as the components that need to be cooled and dissipated heat. Then close the sealed door panel 2 and start the fan 5. The air entering the fan 5 exchanges heat through the refrigeration sheet 4 and cools down. The cooled air enters the telescopic hose 22, the connecting pipe 23 and the sleeve 6 in sequence through the heat exchange cover 3, and is discharged from the first through holes 7. According to the size of the position that needs heat dissipation and cooling, two movable pipes 8 can be pulled out from the sleeve 6, so that part of the cold air is discharged through the second through holes 9, increasing the horizontal span of the cooling and heat dissipation cooling air.

[0029] As Figure 1and Figure 4 As shown in the figure, T-shaped rods 12 are symmetrically installed at the upper and lower positions on both sides of the box body 1. Springs 13 are sleeved on the T-shaped rods 12. A U-shaped plate 14 is arranged between the T-shaped rods 12. Slide holes are respectively opened at the joints of the U-shaped plate 14 and the T-shaped rods 12. A plurality of limiting strips 15 are uniformly fixed on the side of the U-shaped plate 14 close to the box body 1. Buffer blocks 16 are slidably installed on the outer sides of the limiting strips 15. Card slots are opened at the joints of the buffer blocks 16 and the limiting strips 15. The arrangement of the card slots facilitates the disassembly and installation of the buffer blocks 16 and is convenient for clamping on the limiting strips 15. Moreover, the buffer blocks 16 are all semi-circular elastic blocks. The semi-circular elastic blocks not only have elasticity in terms of material to improve the impact resistance, but also the semi-circular shape further increases the impact resistance.

[0030] Specifically, when an object impacts the outer side of the box body 1, it will first contact the U-shaped plate 14. The springs 13 at the upper and lower ends of the U-shaped plate 14 disperse the impact force of the object. The impacted U-shaped plate 14 simultaneously pushes the buffer blocks 16 to move towards the outer side of the box body 1. Under the action of the buffer blocks 16, the impact force is further dispersed. When the buffer blocks 16 are damaged, they can slide out laterally along the limiting strips 15 from the outer sides of the limiting strips 15 and then be replaced.

[0031] As Figure 1 and Figure 5 shown in the figure, a fitting frame 19 is movably installed on the inner side wall of the wire passing port 21. A fixed frame 17 and a limiting frame 20 are respectively fixed on the top and bottom of the fitting frame 19. The limiting frame 20 and the fixed frame 17 are respectively movably connected to the bottom and the inner bottom wall of the box body 1. A plurality of rubber blocking strips 18 are symmetrically and uniformly arranged inside the fitting frame 19. The limiting frame 20, the fixed frame 17 and the fitting frame 19 are all rubber frames. Anti-slip lines are arranged on the top of the fixed frame 17. The rubber-made limiting frame 20, fitting frame 19 and fixed frame 17 are more likely to be pushed to generate deformation, thus facilitating disassembly and maintenance. Connecting ports 24 are respectively opened on one side of the fixed frame 17, the fitting frame 19 and the limiting frame 20.

[0032] Specifically, after the installation in the box body 1 is completed, wires will pass through the wire passing port 21 at the bottom and extend out of the box body 1. The rubber blocking strips 18 and the fixed frame 17 can reduce the situation that dust and impurities easily enter the positions where no wires pass through, and can place wires with different quantities and at different positions. In addition, by squeezing the fixed frame 17, the fixed frame 17, the fitting frame 19 and the limiting frame 20 are deformed simultaneously, and then they can be pulled out from the wire passing port 21.

[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, and all belong to the protection scope of the present invention.
