Description

Technical Field

[0001] This utility model belongs to the field of meter box technology, and in particular relates to an internal moisture-absorbing and moisture-proof meter box. Background Technology

[0002] An electricity meter box is a protective device specifically designed to install electricity metering instruments. It is typically made of plastic, metal, or resin-based composite materials and features waterproof, dustproof, and explosion-proof properties to ensure stable operation of the meter in various environments. The main function of the electricity meter box is to collect and distribute electrical energy, safely transmit electrical energy from the power source to various electrical devices, and record the user's electricity consumption in real time, thereby simplifying the electricity billing process.

[0003] Currently available meter boxes with internal moisture-absorbing and moisture-proof features have the following problems when used:

[0004] 1. Traditional internal moisture-absorbing and moisture-proof meter boxes typically have a drying structure installed inside. Since the drying structure is directly fixed inside the meter box, once its effectiveness weakens due to prolonged use, it can no longer maintain a dry environment inside the meter box, making replacement troublesome. Therefore, it is inconvenient to repair or replace the drying structure during use.

[0005] 2. Most internal moisture-absorbing and moisture-proof meter boxes often have a circuit board structure installed inside the meter box body. The circuit board has many wire harnesses connected inside. Since there is no structure to hold the wire harnesses, the wire harnesses are easily scattered inside, which is time-consuming during subsequent maintenance or equipment inspection. Therefore, no structure to hold the wire harnesses is installed in the application. Utility Model Content

[0029] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an internal moisture-absorbing and moisture-proof meter box.

[0030] like Figure 1-6As shown, this utility model discloses an internal moisture-absorbing and moisture-proof meter box, comprising a meter box body 1 and a door 2. The meter box body 1 is connected to the door 2 via a pivot. The meter box body 1 is provided with a strip plate 4. By installing the strip plate 4, the meter box body 1 and a positioning frame 5 can be connected and fixed. The top of the strip plate 4 is provided with the positioning frame 5, and the outer side of the positioning frame 5 is fitted with a frame 6. The inside of the frame 6 is inlaid with a drying sheet 8. The sides of the strip plate 4 are connected with fixing plates 9, which are symmetrically distributed. The inner side of the fixing plate 9 is connected with a shaft 10, and the outer side of the shaft 10 is fitted with a bushing 11. The bushing 11 is externally connected to a push plate 12, and the push plate 12 is provided with a plate body 13 on its outer side. By installing a shaft 10 on the inner side of the fixed plate 9, installing a bushing 11 on the outer side of the shaft 10, and installing a push plate 12 and a plate body 13 on the outer side of the bushing 11, when the effect of the drying sheet 8 inside the meter box body 1 weakens, the operator first pinches the plate body 13, and then pushes the push plate 12 on the outer side of the bushing 11 to move the drying sheet 8 inside the frame 6 outward. Then the operator takes out a new drying sheet 8 structure and reinstalls it inside the frame 6, which facilitates the maintenance and replacement of the drying structure.

[0031] The meter box body 1 has a limiting frame 14 inside, a limiting plate 15 is embedded inside the limiting frame 14, a connecting plate 16 is provided on the top of the limiting plate 15, a back plate 17 is connected to one side of the connecting plate 16, a threaded sleeve 19 is provided on the outside of the back plate 17, and a clamping ring 20 is connected to the side of the threaded sleeve 19. The clamping rings 20 are evenly distributed. By installing the limiting frame 14 inside the meter box body 1, and installing the limiting plate 15 and the back plate 17 inside the limiting frame 14, and threading the clamping rings 20 to the outside of the back plate 17, the position of the meter box body 1 is fixed. The clamping rings 20 are removed and installed on the outside of the back plate 17. Then the limiting plate 15 on the back of the back plate 17 is embedded inside the limiting frame 14. In this way, not only is the wire harness clamping structure installed inside the meter box body 1, but multiple wire harnesses can also be clamped and fixed during application.

[0032] The frame 6 has a positioning groove 7 inside, and the positioning frame 5 passes through the positioning groove 7. There are four sets of positioning frames 5. Because of the positioning groove 7 and the positioning frame 5, it is easy to install the frame 6 inside the meter box body 1.

[0033] The meter box body 1 has a circuit board 3 inside, and a mounting plate 21 is provided on the side of the circuit board 3. Because of the mounting plate 21, it is easy for the threaded post 22 to pass through the mounting plate 21.

[0034] The meter box body 1 has a threaded post 22 inside. The mounting plate 21 passes through the threaded post 22. The threaded post 22 is connected to the wing nut 23 by external thread. Because of the threaded post 22 and the wing nut 23, the circuit board 3 can be installed inside the meter box body 1 by fastening.

[0035] A threaded rod 18 is provided on the outer side of the back plate 17. The threaded rod 18 is threadedly connected to a threaded sleeve 19. A wire hole 24 is opened inside the meter box body 1. Since there is a threaded rod 18 and a threaded sleeve 19, the clamping ring 20 can be installed on the outside of the back plate 17 by turning the threaded sleeve 19 clockwise, and the clamping ring 20 can be repaired or replaced by turning the threaded sleeve 19 counterclockwise.

[0036] The working principle of this internally moisture-absorbing and moisture-proof meter box is as follows: When using this equipment, the meter box body 1 first needs to be moved to a suitable position. After being moved, it can be placed on a flat surface. However, in order to facilitate the clamping and fixing of the multiple wire harnesses inside the circuit board 3, a limiting frame 14 is installed inside the meter box body 1, and a limiting plate 15 and a back plate 17 are installed inside the limiting frame 14. A clamping ring 20 is threadedly connected to the outside of the back plate 17. First, the door 2 of the meter box body 1 is opened, and then the meter box body 1 is opened. The device is tilted to the side, and then the clamping ring 20 is removed. Next, the threaded sleeve 19 on the back of the clamping ring 20 is threaded onto the outside of the threaded rod 18. The back of the back plate 17 is connected to the limiting plate 15 via the connecting plate 16. Then, the limiting plate 15 on the back of the back plate 17 is embedded inside the limiting frame 14. This allows the clamping structure to be installed inside the meter box body 1. Next, the mounting plate 21 on the side of the circuit board 3 passes through the threaded post 22. The operator then tightens the wing nut 23 on the outside of the threaded post 22 to fix the position of the circuit board 3. Fasteners are then used. Simply install the meter box body 1 in the designated position, then pass the connected wires through the wire hole 24. Next, to facilitate maintenance and replacement of the desiccant 8 inside the meter box body 1, a positioning frame 5 is installed on the outside of the strip plate 4. The positioning frame 5 is fitted onto the outside of the frame 6, and the desiccant 8 is installed inside the frame 6. Then, a shaft 10 is installed on the inside of the fixing plate 9, a bushing 11 is installed on the outside of the shaft 10, and a push plate 12 and a plate 13 are installed on the outside of the bushing 11. When the effect of the desiccant 8 inside the meter box body 1 weakens, the operator... First, hold the plate 13 and rotate the bushing 11 outside the shaft 10 to make the push plate 12 fit against the side of the drying sheet 8. Then push the push plate 12 outside the bushing 11 to move the drying sheet 8 inside the frame 6 outward. Next, remove the drying sheet 8 from inside the frame 6. Then, the staff will take out a new drying sheet 8 structure and reinstall it inside the frame 6. The operation is relatively simple and convenient for maintenance and replacement of the drying structure. Finally, check the inside of the meter box body 1 again. After the inspection is completed, close the door 2 through the pivot.
