Description

Technical Field

[0001] The present invention relates to the technical field of network security, and in particular to a network security isolation protection device. Background Art

[0002] Network security isolation protection devices play a vital role in modern network security architecture. They can effectively reduce security risks caused by external attacks, internal threats and human errors, protect the security of sensitive data and key systems, ensure business continuity, meet compliance requirements, and improve overall network protection capabilities. For industries with high security requirements, such as finance, government, medical and industrial control, network security isolation is an indispensable and important line of defense.

[0003] At present, during the use of existing network security isolation protection devices, the protective shell usually wraps the network security isolator. The network security isolator needs to be taken out of the protective shell before being plugged in, which increases the operation steps and time cost, and frequent disassembly and installation will increase the risk of equipment damage, especially during the removal process, which can easily cause damage to the plug interface or unstable connection. When manually plugging multiple plugs, the operator needs to constantly adjust the position of the plugs and sockets. In scenarios where multiple plugs need to be plugged in frequently, manual plugging is inefficient, which increases the operation time and reduces the efficiency of production or equipment use. After the plug is plugged in, it is easy to be affected by external influences (such as vibration, tension, etc.) and become loose, thereby affecting the normal operation of the network security isolator and making the equipment less practical.

An end cover 3 is provided on the top of the outer box 1, and the end cover 3 is slidably connected to the outer box 1. Four ventilation holes are arranged on the top of the end cover 3, and a dustproof net 4 is arranged in the ventilation hole. The four ventilation holes correspond to the four sides of the network security isolator 8 respectively. A mounting port is arranged on the side wall of the outer box 1, and the mounting port corresponds to the plug interface of the network security isolator 8, which is used to connect the plug assembly with the network security isolator 8. A shield plate 2 is slidably connected to the side wall of the outer box 1, and the shield plate 2 corresponds to the mounting port. When not working, the mounting port is closed by using the shield plate 2 to prevent dust from entering the outer box 1. A support block 6 is fixedly installed on the bottom of the inner wall of the outer box 1, and four nail shafts 22 are slidably connected to the top of the support block 6. The four nail shafts 22 are respectively located at the four corners of the support block 6. A mounting plate 7 is arranged above the support block 6, and the bottom of the mounting plate 7 is fixedly connected to the top of the nail shaft 22 Next, four mounting cavities 18 are provided inside the support block 6, and buffer assemblies are respectively provided inside the four mounting cavities 18. The four groups of buffer assemblies correspond to the four nail shafts 22 respectively. The buffer assembly includes a third electric telescopic rod 19 fixedly installed in the mounting cavity 18, and a transmission disk 20 is slidably connected in the mounting cavity 18.

[0023] Two connecting seats are fixedly installed on the side wall of the mounting plate 7, and the two connecting seats are symmetrically distributed on both sides of the mounting plate 7. The connecting seats are used to install the network security isolator 8 on the top of the mounting plate 7. Two second electric telescopic rods 12 are fixedly installed on the bottom of the inner wall of the outer box 1. The two second electric telescopic rods 12 correspond to the two connecting seats respectively and are located below the connecting seats. After the second electric telescopic rod 12 moves upward and contacts the connecting seat, it pushes the connecting seat to drive the mounting plate 7 to move upward, which is convenient for workers to install the network security isolator 8 on the mounting plate 7. After the installation of the network security isolator 8 is completed, the second electric telescopic rod 12 retracts and finally separates from the connecting seat, so that the mounting plate 7 returns to its original position, and the mounting plate 7 is A fixing rod 5 is fixedly installed on the top, and the top of the fixing rod 5 is installed together with the end cover 3 by bolts. The end cover 3 is slidably connected to the inner wall of the outer box 1. When the network safety isolator 8 and the mounting plate 7 are subjected to upward and downward forces due to being in an unstable environment, the pressure sensor 21 performs pressure detection. When the detection value of the pressure sensor 21 reaches a preset threshold, the third electric telescopic rod 19 contracts and separates from the bottom of the transmission disk 20. The network safety isolator 8 and the mounting plate 7 are affected by their own weight to squeeze the first spring 24. The impact on the network safety isolator 8 is buffered by the expansion and contraction of the first spring 24, thereby reducing direct damage to the network safety isolator 8 and extending the service life of the equipment.

[0024] Two sets of limiting mechanisms are arranged inside the outer box 1, and the two sets of limiting mechanisms are respectively arranged at the diagonally opposite corners of the network safety isolator 8. The limiting mechanisms include a fixing frame 9, which is fixedly mounted on the side wall of the mounting plate 7. A first electric telescopic rod 10 is fixedly mounted on the fixing frame 9. A limiting frame 11 is fixedly mounted on one end of the first electric telescopic rod 10 close to the network safety isolator 8. After the network safety isolator 8 is installed in the outer box 1, the first electric telescopic rod 10 drives the limiting frame 11 to fit with the outer surface of the network safety isolator 8 to fix the network safety isolator 8 and prevent the network safety isolator 8 from displacement.

[0025] Two U-shaped plates 30 are fixedly installed on the inner wall of the outer box 1. The two U-shaped plates 30 are symmetrically distributed up and down. A C-shaped transmission plate 31 is slidably connected between the two U-shaped plates 30. Six clamping drive parts 37 are arranged on the C-shaped transmission plate 31. The six clamping drive parts 37 are located between the two U-shaped plates 30. The six clamping drive parts 37 are divided into three groups in pairs. The three groups of clamping drive parts 37 are linearly distributed on the C-shaped transmission plate 31. Each group of clamping drive parts 37 is symmetrical up and down. Two L-shaped clamping plates 38 are slidably connected to the sides of each group of clamping drive parts 37 away from each other. The two L-shaped clamping plates 38 are symmetrically distributed on the clamping drive parts 37, and the L One end of the L-shaped clamping plate 38 away from the clamping drive part 37 is slidably connected to the U-shaped plate 30 on the corresponding side. The clamping drive part 37 is used to drive the two L-shaped clamping plates 38 to move (the clamping drive part 37 is a prior art, and its internal specific structure and working principle are not repeated here, such as an electric push rod and a hydraulic rod). Three first magnetic blocks 35 are fixedly installed on one side of the two U-shaped plates 30 close to each other. The three first magnetic blocks 35 correspond to the three clamping drive parts 37 on the corresponding side respectively. The plug assembly includes a fixed block 39, a connecting block 34 and a connecting head 41. The connecting block 34 and the connecting head 41 are symmetrically distributed on both sides of the fixed block 39 and are connected to the fixed block 39. 39 is fixedly connected, one end of the connecting block 34 away from the fixing block 39 is fixedly connected with a wire, and the connector 41 is used to connect the plug interface of the network security isolator 8. The fixing block 39 is fixedly mounted with a second magnetic block 36, and the second magnetic block 36 is magnetically opposite to the first magnetic block 35. The corresponding clamping drive part 37 is selected, and the connecting block 34 is inserted between the two L-shaped clamping plates 38 on the clamping drive part 37. The connecting block 34 is pushed so that the fixing block 39 slides along the inner wall of the corresponding U-shaped plate 30 toward the inside of the outer box 1, so that the fixing block 39 exceeds the ends of the two L-shaped clamping plates 38, and the second magnetic block 36 is magnetically connected to the first magnetic block 35 so that the fixing block 39 is fixedly connected to the outer box 1. 9 is initially fixed, and then the clamping drive unit 37 controls the two L-shaped clamps 38 to approach each other. The two L-shaped clamps 38 position and clamp the fixed block 39, so that the fixed block 39 moves to the middle of the clamping drive unit 37, and then the connector 41 is aligned with the plug interface of the network security isolator 8, thereby avoiding misinsertion or poor contact of the connector 41, improving the accuracy of insertion, and reducing the need for manual adjustment. Only the clamping drive unit 37 needs to be started to automatically complete the positioning and clamping of the fixed block 39, and ensure the accurate docking of the connector 41 and the plug interface. This process improves efficiency and reduces the complexity of manual operation.

[0026] The side walls of the two L-shaped clamps 38 are penetrated and fixedly installed with mounting blocks 42. The sides of the two mounting blocks 42 that are close to each other are respectively provided with sliding grooves, and the sliding grooves are slidably connected with trapezoidal embedded blocks 44. The sides of the two trapezoidal embedded blocks 44 that are away from each other are respectively fixedly connected with the mounting blocks 42 with fourth springs 43, and the fourth springs 43 are located in the sliding grooves. Both sides of the fixed block 39 are respectively provided with embedded grooves 40, and the two embedded grooves 40 correspond to the two trapezoidal embedded blocks 44 respectively. When the two L-shaped clamps 38 approach each other to clamp the fixed block 39, if the trapezoidal embedded block 44 is aligned with the embedded groove 40, the trapezoidal embedded block 44 will be embedded in the embedded groove 40. If the positions are not aligned, the trapezoidal embedded block 44 will be squeezed into the sliding groove, and the C-shaped transmission plate 31 is fixedly connected to the support block 6 through the fourth electric telescopic rod 32. Two support rods 33 are fixedly installed on the side of the support block 6 close to the C-shaped transmission plate 31. The two support rods 33 are symmetrically distributed on both sides of the fourth electric telescopic rod 32, and the support rods 33 penetrate the C-shaped transmission plate 31 and are slidably connected to the C-shaped transmission plate 31. After the two L-shaped clamping plates 38 complete the clamping and positioning of the fixed block 39, the fourth electric telescopic rod 32 drives the C-shaped transmission plate 31 to approach the network security isolator 8, so that the connecting head 41 is close to the network security isolator 8, and finally inserted into the plug interface of the network security isolator 8, the trapezoidal embedded block 44 and When the embedding groove 40 is not engaged, the L-shaped clamping plate 38 will continue to move after the connector 41 is embedded in the plug interface, so that the trapezoidal embedding block 44 is finally embedded in the embedding groove 40. When the plug assembly needs to be pulled out, the C-shaped transmission plate 31 is driven by the fourth electric telescopic rod 32, so that the L-shaped clamping plate 38 drives the connector 41 to move in a direction away from the network security isolator 8, so that the connector 41 can be pulled out from the plug interface. The L-shaped clamping plates 38 on both sides of the fixed block 39 that does not need to be pulled out drive the trapezoidal embedding block 44 away from the fixed block 39 under the control of the corresponding clamping drive part 37, and release the connection with the fixed block 39, so that when the L-shaped clamping plate 38 is away from the network security isolator 8, it will not drive the fixed block 39 to move synchronously. The operation of the entire device is controlled by an external control system. The control system controls the clamping drive part 37 corresponding to the fixed block 39 that needs to be pulled out to work. Through the C-shaped transmission plate 31 and the fourth electric telescopic rod 32, the connector 41 can be accurately inserted into or pulled out of the plug interface of the network security isolator 8, reducing manual operations and improving the speed and accuracy of plug-in and pull-out operations. It is especially suitable for occasions of frequent plug-in and pull-out, and can automatically complete the plug-in and pull-out actions, which greatly simplifies the use process and improves the convenience of the overall operation. The precise docking mechanism of the trapezoidal embedded block 44 and the embedded groove 40 ensures high-precision docking in each plug-in and pull-out operation, avoids the risk of looseness and poor contact, and ensures long-term stable operation of the equipment.

At this time, the second magnetic block 36 is magnetically connected to the first magnetic block 35, and the fixing block 39, the connector 41 and the connecting block 34 can be fixed. The clamping drive unit 37 is used to control the two groups of L-shaped clamps 38 to move closer or farther away from each other. When the second magnetic block 36 is magnetically connected to the first magnetic block 35, After the connection, the two groups of L-shaped clamping plates 38 are brought close to each other by the clamping driving part 37, so that the fixing block 39 can be clamped and fixed, the mounting block 42 is fixedly connected to one side of the L-shaped clamping plate 38, the trapezoidal embedded block 44 is slidably arranged inside the mounting block 42, and a fourth spring 43 is fixedly arranged between the trapezoidal embedded block 44 and the mounting block 42, and the fourth spring 43 is used to push the trapezoidal embedded block 44. When the fixing block 39 is clamped, if the position of the trapezoidal embedded block 44 corresponds to the embedded groove 40, the trapezoidal embedded block 44 will be embedded in the embedded groove 40, and if the position does not correspond, the trapezoidal embedded block 44 will be The fourth electric telescopic rod 32 is squeezed into the interior of the mounting block 42, and the C-shaped transmission plate 31 and the multiple groups of clamping drive parts 37 can be driven to move together through the fourth electric telescopic rod 32, so that multiple plugs can be plugged in at the same time. The support rod 33 is arranged through the C-shaped transmission plate 31. The two groups of support rods 33 are used to support the C-shaped transmission plate 31, so that the fourth electric telescopic rod 32 is retracted for a distance, and the connector 41 will be embedded in the plug interface of the network security isolator 8. The L-shaped clamping plate 38 can also prevent the connector 41 from loosening. If the trapezoidal embedding block 44 is not embedded in the embedding groove 40, the connector 41 will be embedded in the plug interface after the L-shaped clamping plate 38 is engaged. The plate 38 will continue to move so that the trapezoidal embedding block 44 is embedded in the embedding groove 40. When the plug assembly needs to be pulled out, the fourth electric telescopic rod 32 is extended to make the multiple groups of L-shaped clamping plates 38 move away from the network safety isolator 8. The transmission of the trapezoidal embedding block 44 can separate the connector 41 from the plug interface, so that the plug assembly can be pulled out, thereby realizing automatic plug-in of the plug assembly without manual alignment, which is easy to use. In addition, through the independent setting of multiple groups of clamping drive parts 37, it can adapt to the joint or individual plug-in use of multiple plug assemblies, which is more efficient.

[0030] When the connector 41 is inserted into the plug interface, the air outlet pipe 17 is located below the connector 41, and the air can be sucked into the outer box 1 from the multiple groups of dustproof nets 4 through the fan 25. The air passes through the support block 6, the guide tube 27, the groove 13, the flow hole 14, the fixing ring 15 and the connecting part 16 and then flows out from the air outlet pipe 17, which can take away the heat of the network safety isolator 8 and dissipate the heat when the device is in use.

[0031] When the device is in an unstable environment during use, the network security isolator 8 will generate upward and downward forces, which can be transmitted to the pressure sensor 21 through the nail shaft 22. When the pressure sensor 21 detects that the force on itself reaches the preset threshold, the plug assembly is first separated from the network security isolator 8 by the clamping drive part 37 and the L-shaped clamping plate 38 to prevent the plug assembly from being damaged due to the vibration of the network security isolator 8. Then the third electric telescopic rod 19 is contracted. Since the third electric telescopic rod 19 is in contact with the transmission disk 20, the dead weight of the network security isolator 8 and the mounting plate 7 can squeeze the first spring 24. The expansion and contraction of the first spring 24 can buffer the impact on the network security isolator 8 and reduce the possibility of damage to the network security isolator 8. The positioning ring 23 is used to limit the moving height of the transmission disk 20. The guide tube 27 and the transmission ring 28 can adapt to the lifting and lowering of the mounting plate 7. The height of the mounting plate 7 and the network security isolator 8 can be adjusted by the second electric telescopic rod 12, which facilitates the removal of the network security isolator 8. The present invention can achieve external protection for the network security isolator 8 without affecting its use, can realize automatic plug-in of the plug assembly, does not require manual alignment, is easy to use, and can dissipate heat for the network security isolator 8 and the plug assembly during use. When the environment is unstable, it can automatically adjust the fixing method of the network security isolator 8, effectively reducing the possibility of damage to the plug assembly and the network security isolator 8, thereby extending the service life of the equipment.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
