[0003] Although the above technology has a certain degree of insulation protection function and dehumidification effect when in use, in actual use, when replacing the activated carbon plate, the relevant staff needs to unscrew the screws to remove the dust screen from the outside of the fixed frame A, and then push the activated carbon plate diagonally to the side so that the activated carbon plate squeezes the placement plate to drive the sliding column compression spring to slide into the inside of the mounting plate. The activated carbon plate at the other end is now detached from the inside of the mounting plate, and the activated carbon plate can be taken out from the inside of the mounting plate and replaced. That is, it is very inconvenient to separate the old activated carbon plate from the box body; therefore, in order to solve the above technical problems, we propose an insulation protection device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0024] Reference Figure 1-6 , an insulation protection device, including a box 1 for providing insulation protection for the meter, a gas circulation component is provided at the upper end of the box 1, a plurality of ventilation holes 2 are provided in the middle of the lower end of the box 1, a matching base 3 is fixed to the lower surface of the box 1 corresponding to the ventilation holes 2, a mounting opening is provided in the middle of the base 3 and a placement box 4 is slidably provided in the mounting opening, inclined force surfaces 8 are provided at both ends of the placement box 4, an activated carbon plate 5 is provided in the placement box 4, matching mounting cavities and top springs 6 are provided in the interior of the two ends of the base 3 corresponding to the placement box 4, and the top spring 6 is close to the placement box 4. A linkage frame 7 is abutted against the end of the linkage frame 7 that is close to the top spring 6 to extend to the outside of the mounting cavity and abut against the force surface 8 located on the lower side, and a matching pressure regulating structure is provided at both ends of the placement box 4 corresponding to the top spring 6. Example 2

[0025] Reference Figure 1-6 , while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0026] The pressure regulating mechanism includes a mounting block 9, a rotating shaft 10 and a pushing plate 11. The mounting block 9 is mounted at one end of the mounting cavity away from the linkage frame 7. One end of the rotating shaft 10 is rotatably connected to the mounting block 9. The other end of the rotating shaft 10 is connected to the pushing plate 11 through a thread. The outer annular surface of the pushing plate 11 abuts against the inner wall of the mounting cavity. The top spring 6 is located between the linkage frame 7 and the pushing plate 11. The setting of the pressure regulating mechanism enables the pushing plate 11 to move horizontally when the rotating shaft 9 rotates, and the pushing plate 11 squeezes or relaxes the top spring 6 when it moves, so that the force applied by the top spring 6 to the linkage frame 7 increases or decreases, thereby achieving the effect of adjusting the force of the linkage frame 7 on the placement box 4. ; One end of the rotating shaft 9 away from the top spring 6 extends to the outside of the mounting block 9 and is equipped with a force block 12. The cross-section of the force block 12 is hexagonal. The setting of the force block 12 makes it convenient for personnel to rotate the rotating shaft 9; one end of the linkage frame 7 away from the top spring 6 is equipped with a number of rollers 13. The end of the linkage frame 7 contacts the force-applying surface 8 of the end of the placement box 4 through the rollers 13. The setting of the rollers 13 reduces the friction resistance between the linkage frame 7 and the placement box 4, so that the elastic force of the top spring 6 can be applied to the force-applying surface 8 more smoothly, that is, the top spring 6 can push the placement box 4 upward or downward more smoothly through the rollers 13, that is, it is convenient for the placement box 3 to be combined with or separated from the base 3.

[0027] The lower side of the placement box 4 is open and is provided with a sealing door 14. A handle is provided on the lower surface of the sealing door 14. Both the placement box 4 and the sealing door 14 are provided with a number of ventilation holes. The setting of the sealing door 14 facilitates the sealing of the opening on the lower side of the placement box 4, thereby facilitating the replacement of the activated carbon plate 5 inside the placement box 4; the lower surface of the box body 1 is provided with a matching sealing ring 15 corresponding to the ventilation hole 2, and the lower surface of the sealing ring 15 abuts against the upper surface of the placement box 4. The setting of the sealing ring 15 improves the sealing between the placement box 4 and the box body 1; the gas circulation component includes a fan 16 and an air duct 17. The upper end of the air duct 17 is connected to the upper end of the box body 1, and the fan 16 is installed on one side of the box body 1. The lower end of the air duct 17 is connected to the fan 16. The setting of the gas circulation component facilitates the circulation of the gas inside the box body 1, thereby having a dehumidification effect therein.

[0028] Principle and advantages of use: During use, the present invention cooperates with the placement box 4, the box body 1 and the gas circulation assembly to allow the air inside the box body 1 to circulate with the outside air, that is, the outside air passes through the placement box 4 and the activated carbon plate 5 and enters the bottom of the box body 1 through the ventilation hole 2, and then is discharged from the air guide pipe 17 at the upper end of the box body 1 by the fan 16. Therefore, in the process of gas circulation, it can not only dissipate heat, cool down and dehumidify the meter inside the box body 1; at the same time, in the above process, when the activated carbon plate 5 needs to be replaced, the staff directly pulls the handle so that the handle drives the placement box 4 to move downward through the sealed door 14, that is, the two sides of the placement box 4 are The force-applying surface 8 at the end squeezes the roller 13, so that the roller 13 rolls along the force-applying surface 8, and the roller 13 pushes the linkage frame 7 to move into the installation cavity. At this time, the linkage frame 7 compresses the top spring 6, and when the roller 13 jumps over the intersection of the force-applying surface 8 at the same end, the roller 13 can push the force-applying surface 8 to move downward, that is, prompting the placement box 4 to quickly separate from the base 3. Then the personnel pushes the new placement box 4 directly into the base 3 until the intersection of the force-applying surface 8 jumps over the roller 13. Under the action of the top spring 6, the linkage frame 7 pushes the roller 13 to move toward the placement box 4, that is, the roller 13 pushes the placement box 4 to move upward, thereby achieving the limitation and fixation of the placement box 4.

[0029] In summary, when the present solution is used, by setting the placement box 4, top spring 6, linkage frame 7 and force application surface 8, personnel can directly and quickly replace the placement box 4 when replacing the activated carbon board 5, and then slowly replace the old activated carbon board 5 in the old placement box 4. Therefore, compared with the traditional solution, when the present solution is used, the old activated carbon board 5 can be conveniently separated from the box body 1 and quickly replaced with a new activated carbon board 5, thereby effectively improving the convenience of the present solution when used, that is, solving the defect that the old activated carbon board 5 cannot be quickly and conveniently separated or installed from the box body 1 when the traditional solution is used; and because the activated carbon board 5 is arranged in the base 3, when it rains outside, the rainwater outside is not easy to erode the activated carbon board 5, thereby extending the service life of the activated carbon board 5.

[0030] It should be further explained that the setting of the pressure regulating mechanism enables the pushing plate 11 to move horizontally when the rotating shaft 9 rotates, and the pushing plate 11 squeezes or relaxes the top spring 6 when it moves, so that the force applied by the top spring 6 to the linkage frame 7 increases or decreases, thereby achieving the effect of adjusting the force of the linkage frame 7 on the placement box 4; the setting of the force block 12 makes it easier for personnel to rotate the rotating shaft 9; the setting of the roller 13 reduces the friction resistance between the linkage frame 7 and the placement box 4, so that the elastic force of the top spring 6 can be more smoothly applied to the force application surface 8, that is, the top spring 6 can push the placement box 4 upward or downward more smoothly through the roller 13, so as to facilitate the combination or separation of the placement box 3 and the base 3; the setting of the sealing door 14 facilitates the sealing of the opening on the lower side of the placement box 4, thereby facilitating the replacement of the activated carbon plate 5 inside the placement box 4; the setting of the gas circulation component facilitates the circulation of the gas inside the box body 1, thereby achieving a dehumidification and heat dissipation effect inside it.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
