Description

Technical Field

[0001] This utility model relates to the field of network security technology, and more specifically to a network security isolation device. Background Technology

[0002] Network security refers to the protection of a network system's hardware, software, and data from accidental or malicious damage, alteration, or disclosure, ensuring continuous, reliable, and normal system operation and uninterrupted network services. Network isolation devices enhance network security by dividing the network into multiple independent zones and restricting the flow of data between these zones.

[0003] The shortcomings of existing technologies: The internal structure of existing network security isolation devices is too compact. When the device is repaired or replaced, a large number of parts need to be disassembled, which makes the operation process more complicated and makes the device less convenient to maintain. At the same time, the compact internal structure limits the expansion space and makes it impossible to add new functional modules or expand the equipment. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a network security isolation device to solve the problem that the internal structure of the existing network security isolation device in the background art is too compact, resulting in inconvenient maintenance of the device and limited expansion space, making it impossible to add new functional modules or expand the equipment.

[0022] Furthermore, such as Figure 2 As shown, the expansion component 5 includes an expansion plate 51 that is hinged to one side of the bottom of the outer casing 1. The hinge is set to rotate at an angle of 90 degrees, so that the expansion plate 51 rotates to a horizontal position. An installation groove 52 is provided in the middle of the expansion plate 51. When there is not enough installation space in the inner cavity of the device, the expansion plate 51 is rotated to unfold it, and the added functional module or expansion device is installed in the inner cavity of the installation groove 52, which effectively increases the expansion space and practicality of the device. A fixing plate 53 is fixedly connected to the top of the expansion plate 51.

[0023] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, a first mounting hole 54 is provided in the middle of the fixing plate 53, and two second mounting holes 8 are provided at the top of the outer shell 1. The fixing plate 53 is movably connected to the top of the outer shell 1. The first mounting hole 54 and the second mounting holes 8 are connected and communicate with each other. The inner cavities of the first mounting hole 54 and the second mounting hole 8 are provided with connecting bolts. When no installation space for the expansion device is required, the expansion plate 51 is connected to the outer shell 1, and the fixing plate 53 is located at the top of the outer shell 1. The position of the expansion plate 51 is fixed by using connecting bolts through the first mounting hole 54 and the second mounting hole 8.

[0024] Furthermore, such as Figure 1 and Figure 4 As shown, the bottom end of the positioning mounting plate 2 has two positioning grooves 10. Both ends of the positioning mounting plate 2 are fixedly connected to two connecting ear plates 11. The four connecting parts 3 and connecting blocks 4 are arranged in a rectangular array. The connecting blocks 4 are movably connected to the inner cavity of the positioning grooves 10. When installing the isolation device, the positioning mounting plate 2 is first installed in the designated position, and then the outer shell 1 is connected to the positioning mounting plate 2 through the connecting blocks 4. This helps to determine the installation position of the device and makes the installation and disassembly of the device more convenient.

[0025] Furthermore, such as Figure 2 As shown, a limiting slot 12 is provided on the lower part of the inner wall of the outer shell 1. Slider 13 is fixedly connected to both ends of the equipment plate 9. A push block 14 is fixedly connected to one side of the bottom end of the equipment plate 9. The slider 13 is movably connected to the inner cavity of the limiting slot 12. All electronic components in the isolation device are installed on the equipment plate 9. When it is necessary to repair or replace the internal electronic components, push the push block 14 to move the equipment plate 9 out of the inner cavity of the outer shell 1. This allows the staff to directly repair or replace the electronic components installed on the equipment plate 9 without disassembling the device, reducing the difficulty of operation. During the movement of the equipment plate 9, the slider 13 moves in the inner cavity of the limiting slot 12, which effectively increases the stability of the movement of the equipment plate 9.

The first through hole 15 and the second through hole 16 are connected and communicate with each other. When the device plate 9 is moved out of the inner cavity of the outer shell 1, it pushes the cover 6, causing the cover 6 to rotate and flip up, which facilitates the removal of the device plate 9. When the device plate 9 is not moved, the cover 6 is closed with the outer shell 1. The positions of the first through hole 15 and the second through hole 16 correspond to each other. The positions of the cover 6 and the device plate 9 are fixed by using connecting bolts through the first through hole 15 and the second through hole 16.

After installation, the connecting block 4 at the top of the outer shell 1 is connected to the inner cavity of the positioning groove 10. After connection, it is fixed by connecting bolts. All electronic components in the isolation device are installed on the equipment plate 9. When the equipment plate 9 is inside the outer shell 1, the cover 6 is closed with the outer shell 1. The positions of the first through hole 15 and the second through hole 16 correspond. Connecting bolts are used to fix the positions of the cover 6 and the equipment plate 9 through the first through hole 15 and the second through hole 16. When it is necessary to repair or replace the electronic components, the connecting bolts are removed. Then, the push block 14 is pushed to move the equipment plate 9 out of the inner cavity of the outer shell 1. When the equipment plate 9 is moved out, the cover 6 is pushed to make The cover 6 can be rotated upwards and opened, allowing staff to directly repair or replace the electronic components installed on the device board 9 without disassembling the device, reducing operational difficulty. During the movement of the device board 9, the slider 13 moves within the limit slot 12, effectively increasing the stability of the device board 9. When it is necessary to add new functional modules or expand the device, the connecting bolts in the first mounting hole 54 and the second mounting hole 8 are removed, and the expansion plate 51 is rotated 90 degrees to a horizontal position via the hinge, increasing the expansion space of the device. The added electronic components are installed in the mounting slot 52, and the connecting wires of the electronic components installed on the expansion plate 51 are connected to the device in the inner cavity of the outer shell 1 through the connecting slot 7, effectively increasing the practicality of the device.
