[0002] A network firewall is a special network interconnection device used to strengthen access control between networks. All network communications flowing in and out of a computer must pass through this firewall. The firewall scans the network communications flowing through it, so that some attacks can be filtered out to prevent them from being executed on the target computer.

[0003] After retrieval, the publication number is CN214799531U, and the name is a network firewall device, including a storage box and a device main body. Through research and analysis, it is found that although the storage box can play a role in protecting the device main body, and it is also relatively convenient to use the device main body when needed, just pull the clamping plate until it no longer blocks the device main body. However, to a certain extent, there are still the following defects.

[0004] For example, it is not convenient to repair and detect the components inside the device. The outer shell of the above-mentioned firewall device is installed and fixed by bolts, and personnel need to use tools to operate when disassembling. This not only increases the labor intensity of personnel, but also reduces the efficiency of component repair and detection due to the time-consuming and laborious disassembly. At the same time, the shock absorption effect is not good. When the device is fixed on a moving object, the frequent vibration during the movement will cause the internal components to loosen and fall off, thus triggering a failure and increasing the maintenance cost. To solve the above technical problems, we designed a network firewall device convenient for detection. Content of the Utility Model

The top of the support vertical plate 21 is bolted with the device main board 9;

[0026] Please refer to Figure 3, a sliding opening 23 is provided on the front side of the fixed housing 14. The front side of the connecting sliding plate 12 penetrates through the sliding opening 23 and is fixedly connected with a push plate 11. By providing the push plate 11, it can make it more labor-saving for personnel to push the connecting sliding plate 12;

[0027] Please refer to Figure 1 and Figure 2 , one side of the plug-in plate 10 away from the connecting sliding plate 12 penetrates through the fixed housing 14 and extends into the inner cavity of the positioning plug housing 2. The left side of the main housing 1 is fixedly connected with a cable interface 22 through penetration;

[0028] Please refer to Figure 5 , a through opening 24 is provided at the bottom of the inner cavity of the main housing 1.

[0029] During use, connect the device to an external power supply and then connect to the network cable for normal use. When it is necessary to repair and detect the components inside the device, push the push plates 11 on both sides outward simultaneously. The push plates 11 drive the plug-in plate 10 to move out of the positioning plug housing 2 through the connecting sliding plate 12. At this time, the user can pull the front side of the cover plate 5 upward to open the top of the main housing 1. At this time, the user repairs and detects the components on the device main board 9. After the detection is completed, push the push plates 11 outward simultaneously again. The connecting sliding plate 12 compresses the positioning spring 13 and the plug-in plate 10 moves into the fixed housing 14. At this time, cover the cover plate 5. When it is completely closed, release the push plates 11. The positioning spring 13 releases its elastic force to push the plug-in plate 10 inside the connecting sliding plate 12 into the internal part of the positioning plug housing 2, so that the fixing of the cover plate 5 can be completed. The disassembly and assembly are more convenient and fast, and there is no need for personnel to use tools for operation, which is more time-saving and labor-saving, improving the repair and detection efficiency. When the device is installed on a moving carrier, frequent vibrations will occur as the object moves. At this time, the vibration energy is transmitted from the bottom to the support sliding plate 16 to make it move up and down. During the movement, the shock absorption spring 18 is compressed. The shock absorption spring 18 can offset the transmitted kinetic energy through its own compression to damp the equipment main body above, so that the components on the device main board 9 can be prevented from loosening or falling off through vibration damping, effectively reducing the failure rate.
