Description

Technical Field

[0001] This utility model belongs to the field of network security, specifically relating to a signal shielding device for information network security. Background Technology

[0002] A signal jammer is a signal blocking device used in network security, such as a mobile phone signal jammer or a WiFi jammer. It is mainly used to block wireless communication on specific frequency bands to prevent information leakage or to ensure communication control in a specific area.

[0003] Existing network security signal jamming devices emit interference signals in the same frequency band as the target signal, preventing the receiving device from properly interpreting the valid information. When operating at high power, the jammer's temperature is high, which can lead to performance degradation. Common jammers usually use fans to cool the device, but after prolonged use, dust drawn in by the fan will gradually accumulate, leaving a large amount of dust inside the device, which may cause the jammer to malfunction. However, the internal structure of common jammers is relatively complex, and the device is usually fixed in a box, making it inconvenient to clean and maintain the device. Utility Model Content

[0004] To overcome the inconvenience of cleaning or maintaining the internal components of signal jamming devices used for network security, a signal jamming device for information network security is proposed.

[0005] The technical solution of this utility model is as follows: a signal shielding device for information network security, comprising a box and a shield. The shield is provided on the inner wall of the box. The lower inner wall of the box is fixedly connected with left and right distributed locking blocks and a fixing frame. The lower end of the shield is provided with a locking groove, and the locking blocks are adapted to the locking groove. The upper edge of the locking blocks is provided with left and right symmetrical slots, and spring pins are fixedly connected in the slots. The rear end of the spring pins is attached to the front end of the shield, and the rear end of the shield is attached to the rear inner wall of the box. The front end of the box is provided with a first slot, and a heat dissipation fin is slidably arranged in the first slot. The upper and lower ends of the box are provided with a second slot, and a cooling fan is fixedly connected in the second slot. The inner wall of the fixing frame is slidably provided with a filter screen, and a magnetic block is fixedly connected to the rear end of the filter screen. A magnetic plate is fixedly connected to the rear inner wall of the fixing frame, and the magnetic plate is adapted to the magnetic block. The rear end of the box is provided with a third slot, and an antenna is installed in the third slot.

[0006] Furthermore, the front end of the spring pin is curved, and the second groove corresponds one-to-one with the fixed frame.

[0007] Furthermore, a power supply is fixed to the inner wall of the rear end of the box. The power supply is electrically connected to the shield, and the upper end of the power supply and the shield are attached to the lower end of the heat dissipation fins.

[0008] Furthermore, the exhaust end of the cooling fan located on the lower side is in contact with the filter screen, while the exhaust end of the cooling fan located on the upper side is flush with the top of the box.

[0009] Furthermore, the rear end of the antenna has left and right distributed limiting holes, and bolts are installed in the limiting holes. The groove three has left and right symmetrical screw holes, and the bolts pass through the limiting holes and are threaded into the screw holes.

[0010] Furthermore, the antenna is electrically connected to the shield, the front opening of the box is hinged with a door, the rear end of the door fits against the front end of the heat sink fins, and a door lock is installed on the door.

[0011] Furthermore, the output ends of shock absorbers are fixed to the four corners of the lower end of the box, and the fixed ends of the shock absorbers are fixed to the base frame.

[0012] The beneficial effects of this utility model are as follows: the shield can be limited by sliding the slot on the outer wall of the card block, and the spring pin can be used to fix the shield, improving the convenience of installation and disassembly of the shield. The filter screen that is slidably installed in the fixed frame can be easily removed. The magnetic block and magnetic plate can limit and fix the filter screen. Furthermore, the heat dissipation fins that are slidably installed in the first slot can be easily removed. Compared with existing signal shielding equipment for network security, the added card block and fitting pin structure can facilitate the installation and disassembly of the shield. The heat dissipation fins that are slidably installed in the first slot can be easily removed and cleaned. The filter screen that is limited by the fixed frame, magnetic block and magnetic plate can further improve the convenience of disassembly, making it easier to clean and maintain the equipment inside the box.

[0023] Please see Figure 3In this embodiment, the front end of the spring pin 9 is an arc surface, and the groove 11 corresponds one-to-one with the fixed frame 14. When in use, the shield 3 is pushed backward through the arc surface of the front end of the spring pin 9, and the spring pin 9 can retract into the groove 8. The power supply 12 is fixedly connected to the inner wall of the rear end of the box 1. The power supply 12 is electrically connected to the shield 3. The upper end of the power supply 12 and the shield 3 are in contact with the lower end of the heat dissipation fin 4. When in use, the heat dissipation fin 4 can dissipate heat from the shield 3 and the power supply 12. The power supply 12 can provide power to the shield 3 when the power is off.

[0024] Please see Figures 4-5 In this embodiment, the air outlet of the cooling fan 13 located on the lower side is in contact with the filter screen 5, and the air outlet of the cooling fan 13 located on the upper side is flush with the upper end of the box 1.

Rotate and screw in bolt 20 to complete the installation of antenna 17. Next, align the slot 6 with the front end of the block 7 and push the shield 3 backward so that the rear end of the shield 3 fits against the inner rear end of the box 1 and the spring pin 9 pops out. Then, align the heat dissipation fin 4 with slot 10 and push the heat dissipation fin 4 backward. Align the filter 5 with the front opening of the fixing frame 14 and push the filter 5 backward so that the magnetic block 15 fits against the magnetic plate 16. Finally, connect the shield 3 to the power supply 12 and the antenna 17, close the box door 21, start the cooling fan 13, and plug in the power cord of the shield 3.
