Description

Technical Field

[0001] This utility model relates to the field of network security isolation technology, specifically to an isolation device for information network security. Background Technology

[0002] Network security isolation devices are devices that use physical or logical isolation technologies to block direct network connections, enabling one-way or two-way data transmission between networks with different security levels. They are mainly used to prevent data leakage and attack penetration.

[0003] The prior art disclosure number CN218473637U discloses an isolation device for information network security, relating to the field of network security isolation technology. It includes an isolation box, an isolation unit, and an installation unit. The isolation box is a vertically placed cuboid. The isolation unit includes a fixed shaft, a door panel, a fixed plate, a placement plate, a locking post, an L-shaped plate, a spring, a mounting base, and an isolation device body. The placement plate is located above the fixed plate. The lower end of the locking post engages with a groove on the upper end of the mounting base. The isolation device body is located on the upper interior side of the isolation box. The installation unit is installed on the upper interior side of the isolation box. Multiple detachable placement plates are provided to hold electrical components. Various sizes of electrical components can be placed and fixed by removing the placement plates, broadening the application range. In addition to the isolation box, the installation unit also houses the isolation device body, enhancing the isolation effect. Furthermore, the installation unit allows for the installation of isolation device bodies of different sizes, further expanding the application range.

[0004] With the above configuration, the existing isolation equipment uses multiple detachable placement plates to hold electrical components. This allows for the placement and fixing of electrical components of various sizes by removing the placement plates, thus broadening its application range. Furthermore, it not only includes an isolation box but also an internal isolation device body, enhancing the isolation effect. Additionally, different sizes of isolation device bodies can be installed via the mounting unit, further expanding its application range. However, the existing isolation equipment has the following drawbacks during operation:

[0005] After prolonged use, dust accumulates on the filter screen fixed to the vent of the isolation device described in the prior art. Therefore, the filter screen needs to be disassembled, replaced, and cleaned. However, disassembly usually requires unscrewing screws, which is very troublesome and time-consuming. It is not possible to quickly disassemble and replace the clogged filter screen, which affects the heat dissipation effect of the isolation device. Utility Model Content

[0006] This utility model aims to provide an isolation device for information network security, mainly to solve the technical problem that the filter screen will become clogged with dust after long-term use, affecting the heat dissipation effect and making it impossible to quickly replace the filter screen.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An isolation device for information network security includes an isolation box and a filter screen. The outer wall of the isolation box has heat dissipation holes, and a fixed frame is installed on the inner wall of the heat dissipation holes. The filter screen is fixedly connected to the inner wall of the fixed frame. The inner wall of the heat dissipation holes has a movable groove, and a limiting component for fixing the fixed frame is provided inside the movable groove. A protective cover is installed on the outer wall of the isolation box, and the protective cover covers the outer wall of the filter screen.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the filter screen becomes clogged and needs to be replaced quickly, first pull the protective cover, so that the protective cover moves the T-shaped rod inside the T-shaped groove, so that the T-shaped rod is disengaged from the vertical rod. Then adjust the limiting component so that the limiting plate is disengaged from the limiting groove. Then, under the action of the compression spring's rebound force, push the fixed frame to move, and then you can pull the fixed frame to pull out the filter screen, and then you can replace it with a new filter screen.

[0011] 2. Beneficial effects:

[0012] Existing technology uses multiple detachable mounting plates to hold electrical components, allowing for the placement and fixing of components of various sizes by removing the mounting plates, thus broadening the application range. Furthermore, it not only includes an isolation box but also an internal isolation device body to enhance the isolation effect. Additionally, different sized isolation device bodies can be installed via mounting units, further expanding the application range. However, after prolonged use, dust accumulates on the filters fixed to the vents of existing isolation equipment, requiring filter removal, replacement, and cleaning. This typically involves unscrewing screws for removal, which is cumbersome and time-consuming. The inability to quickly disassemble and replace clogged filters affects the heat dissipation of the isolation equipment. This solution addresses this issue by setting up a fixed frame, limiting components, a protective cover, and a cooling fan. The limiting components secure the fixed frame with the filter inside the heat dissipation holes, and the protective cover protects it. The cooling fan expels hot air from inside the isolation chamber, improving its heat dissipation efficiency. By pulling the pull plate on the limiting components, the limiting plate is disengaged from the limiting groove, allowing for filter replacement. This makes disassembly and replacement very convenient and provides a more secure fixation of the filter, thus improving the heat dissipation of the isolation chamber.

[0013] Preferably, the limiting component includes a limiting plate, which is slidably connected to the inner wall of the movable groove. Multiple symmetrical limiting springs are fixedly connected to the inner wall of the movable groove, with the other end of each spring fixedly connected to the limiting plate. A limiting groove is formed on one side of the fixed frame, and the limiting plate is inserted into the limiting groove. A pull groove is formed on the outer wall of the isolation box, and a pull plate is slidably connected to the inner wall of the pull groove. One side of the pull plate is fixedly connected to the limiting plate. By setting the limiting component, the filter and the fixed frame can be quickly disassembled and installed, facilitating the replacement of clogged filters.

[0014] Preferably, symmetrical vertical rods are fixed to the outer wall of the isolation chamber, with the vertical rods fixed to both sides of the heat dissipation holes. A T-shaped groove is formed on the upper surface of the vertical rod, and a T-shaped rod is slidably connected to the inner wall of the T-shaped groove. One side of the T-shaped rod is fixed to the protective cover. By setting the vertical rods, T-shaped grooves, and T-shaped rods, the protective cover can be limited, allowing it to be installed on the outer wall of the isolation chamber, providing dust protection for the filter screen and preventing dust from falling directly onto it.

[0015] Preferably, a movable groove is provided on one side of the fixed frame, a movable block is slidably connected to the inner wall of the movable groove, a compression spring is fixedly connected to the inner wall of the movable groove, the other end of the compression spring is fixedly connected to the movable block, and the end of the movable block away from the compression spring abuts against the inner wall of the heat dissipation hole. By setting the movable block and the compression spring, the movable block and the fixed frame are pushed to move under the action of the spring's rebound force, so that the fixed frame is disengaged from the heat dissipation hole, making it convenient to disassemble the filter screen.

[0016] Preferably, a support plate is fixed to the bottom of the inner wall of the protective cover, and perforations are formed on the surface of the support plate. A cooling fan is fixed to the inner wall of the perforations. By setting up the support plate and the cooling fan, the hot air exhausted from inside the isolation box can be quickly discharged, improving the heat dissipation efficiency inside the isolation box.

[0017] Preferably, the end of the limiting plate away from the limiting spring has a bevel, and the bevel faces the opening of the heat dissipation hole. By setting the bevel, the installation of the fixing frame can be facilitated.

[0018] Preferably, the outer wall of the pull plate is fixed with an anti-slip pad to increase the friction between the fingers and the pull plate. Attached Figure Description

[0026] like Figure 1-4 As shown, an isolation device for information network security includes an isolation box 1 and a filter 2. The outer wall of the isolation box 1 has heat dissipation holes 3, and a fixed frame 8 is installed on the inner wall of the heat dissipation holes 3. The filter 2 is fixedly connected to the inner wall of the fixed frame 8. A movable groove 4 is formed on the inner wall of the heat dissipation holes 3. A limiting component for fixing the fixed frame 8 is disposed inside the movable groove 4. The limiting component includes a limiting plate 6, which is slidably connected to the inner wall of the movable groove 4. Multiple symmetrical limiting springs 7 are fixedly connected to the inner wall of the movable groove 4, and the other end of each limiting spring 7 is fixedly connected to the limiting plate 6. A limiting groove 9 is formed on one side of the fixed frame 8, and the limiting plate 6 is inserted into the limiting groove 9. An inclined surface 2 is formed on the end of the limiting plate 6 away from the limiting springs 7. 1. The inclined surface 21 faces the opening of the heat dissipation hole 3. The outer wall of the isolation box 1 is provided with a groove 10. The inner wall of the groove 10 is slidably connected with a pull plate 11. One side of the pull plate 11 is fixedly connected to the limiting plate 6. The outer wall of the isolation box 1 is equipped with a protective cover 5, which covers the outer wall of the filter screen 2. The outer wall of the isolation box 1 is fixedly connected with symmetrical vertical rods 12. The vertical rods 12 are fixedly connected to both sides of the heat dissipation hole 3. The upper surface of the vertical rods 12 is provided with a T-shaped groove 13. The inner wall of the T-shaped groove 13 is slidably connected with a T-shaped rod 14. One side of the T-shaped rod 14 is fixedly connected to the protective cover 5. The bottom of the inner wall of the protective cover 5 is fixedly connected with a support plate 18.
