Description

Technical Field

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

[0002] Network security refers to the protection of the hardware, software and data of the network system from damage, change or leakage due to accidental or malicious reasons. The system runs continuously, reliably and normally, and network services are not interrupted. Network security includes network equipment security, network information security and network software security. Network isolation technology can not only achieve physical isolation of the network, but also exchange data in a secure network environment. The main goal of network isolation technology is to isolate harmful network security threats to ensure the secure interaction of data information within a trusted network.

[0003] The existing isolation device has certain defects in actual use. The existing isolation device does not have a network cable locking structure or an arrangement structure, which easily causes the network cables to be entangled, which is not conducive to subsequent cable management or maintenance. In addition, during normal use, the network equipment needs to be installed in the isolation device, and the network cable and the network equipment are mostly plug-in or installed with a snap-on fit through a crystal head. During daily use, once the network cable is accidentally touched and pulled, the connector of the network cable will be separated from the connection port of the network device. However, from the outside of the isolation device, it is impossible to promptly discover the separation between the network cable and the network device, thereby affecting the maintenance of the network and being not conducive to actual use.

[0017] The beneficial effects of the present invention are:

[0018] 1.

[0019] 2. After the network device is fixed to the mounting seat, drive the mounting seat to move downward through the capping mechanism, and the mounting seat drives the network device to move to the lower end of the inner cavity of the shielding isolation box.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 12, the present invention provides a technical solution: a network security shielding and isolation device, including a shielding and isolation box 1. A docking groove 13 is provided on the front side of the shielding and isolation box 1. On both the left and right sides of the shielding and isolation box 1, limiting plates 14 are fixedly connected symmetrically before and after. A capping mechanism is slidably installed up and down at the upper end of the shielding and isolation box 1. Locking mechanisms are symmetrically installed on the lower end of the capping mechanism left and right. The locking mechanisms are connected to the limiting plates 14 and are located between the two limiting plates 14. The upper end of the shielding and isolation box 1 is open. An installation seat 4 is arranged in the inner cavity of the shielding and isolation box 1 below the capping mechanism. The installation seat 4 is connected to the capping mechanism through a guiding plate 43. The installation seat 4 is used for placing network devices. A clamping mechanism for clamping network devices is installed on the installation seat 4. On the front side of the shielding and isolation box 1, outside the docking groove 13, an isolation box 16 is fixedly connected. In the isolation box 16, a primary locking mechanism and a secondary locking mechanism are installed in sequence from bottom to top.

[0037] Please refer to Figure 1 , Figure 2 , Figure 11 and Figure 12 , on both the left and right sides of the shielding and isolation box 1, convex grooves 11 are symmetrically provided. The upper end of the convex groove 11 does not penetrate the upper end of the side of the shielding and isolation box 1, and the lower end of the convex groove 11 penetrates downward through the lower end of the side of the shielding and isolation box 1. The capping mechanism includes an isolation cover 2 installed at the upper end of the shielding and isolation box 1. At the lower end of the isolation cover 2, supporting plates 21 are fixedly connected symmetrically left and right. The two supporting plates 21 are respectively in sliding contact with the left and right sides of the shielding and isolation box 1 up and down. The lower ends of the two supporting plates 21 are respectively fixedly connected to the two locking mechanisms. On the side of the two locking mechanisms close to each other, convex blocks 24 are fixedly connected. The convex blocks 24 are slidably connected to the convex grooves 11 up and down.

[0038] Please refer to Figure 2 , Figure 3 and Figure 12 , the locking mechanism includes a connecting block 22 fixedly installed at the lower end of the supporting plate 21. Circular grooves 23 are symmetrically provided at both ends of the connecting block 22. In both circular grooves 23, circular blocks 3 are slidably installed back and forth. At one end of the two circular blocks 3 away from each other, locking rods 31 are fixedly connected. At one end of the two circular blocks 3 close to each other, locking springs 32 are inserted. At the upper end of the side of the two circular blocks 3, push blocks 33 are fixedly connected. The connecting block 22 is arranged between the two limiting plates 14. Locking holes 15 are symmetrically provided up and down on the side of the limiting plate 14. One end of the locking rod 31 passes through the connecting block 22 and is inserted into the locking hole 15. The locking rod 31 is slidably connected to the connecting block 22 left and right.

[0039] When the isolation cover 2 is in sealed contact with the upper end of the shielding isolation box 1, the locking rod 31 is inserted into the lower locking hole 15 on the limiting plate 14. When the isolation cover 2 moves upward to open and separate from the shielding isolation box 1, the locking rod 31 is inserted into the upper locking hole 15 on the limiting plate 14.

[0040] One end of the locking spring 32 away from the circular block 3 is inserted into one end of the circular groove 23 close to the inner side. The locking spring 32 exerts an elastic force on the circular block 3. An activity groove is formed by upward penetration at the upper end of the circular groove 23. The upper end of the push block 33 penetrates through the activity groove upward and extends to the outside. The push block 33 is slidably connected to the activity groove in the front and back directions.

[0041] When it is necessary to open the shielding isolation box 1, the two push blocks 33 on the connection blocks 22 on both sides of the shielding isolation box 1 are pushed close to each other. The circular block 3 is driven by the push block 33 to slide inward along the circular groove 23. The circular block 3 presses the locking spring 32. At the same time, the circular block 3 drives the locking rod 31 to move out of the lower locking hole 15 on the limiting plate 14. At this time, the connection block 22 is pushed upward. The connection block 22 drives the isolation cover 2 to move upward through the support plate 21, so that the isolation cover 2 is separated from the shielding isolation box 1. After the isolation cover 2 moves upward a certain distance, the pressing on the push block 33 is released.

[0042] When the connection block 22 moves upward, it drives the convex block 24 to slide upward along the convex groove 11. When the convex block 24 moves to the uppermost end of the convex groove 11, the isolation cover 2 moves to the uppermost position. At this time, under the action of the elastic force of the locking spring 32, the circular block 3 moves outward along the circular groove 23. The circular block 3 drives the locking rod 31 to slide outward along the connection block 22. At the same time, the locking rod 31 is inserted into the upper locking hole 15 on the limiting plate 14, so that the connection block 22 and the limiting plate 14 are relatively fixed; the connection block 22 supports the support plate 21, and the support plate 21 supports the isolation cover 2. At this time, operations such as the installation or disassembly of network devices can be conveniently carried out.

[0043] Please refer to Figure 6 and Figure 11 As shown in the figure, on the left and right side walls of the inner cavity of the shielding isolation box 1, guiding grooves 12 are symmetrically arranged in the front and back directions. On the left and right sides of the mounting seat 4, guiding plates 43 are symmetrically and fixedly installed in the front and back directions. The guiding plates 43 are slidably connected to the upper ends of the guiding grooves 12.

[0044] When the isolation cover 2 moves up and down, it drives the guide plate 43 to move up and down. The guide plate 43 slides up and down along the guide groove 12, so that the guide plate 43 drives the mounting seat 4 to move up and down stably. When the isolation cover 2 moves upward, it drives the mounting seat 4 to move upward from the bottom of the inner cavity of the shielding isolation box 1 to the upper end, which is convenient for installing or disassembling network devices on the mounting seat 4; when the isolation cover 2 moves downward, it drives the mounting seat 4 to move downward through the guide plate 43, so that the mounting seat 4 moves downward from the upper end of the inner cavity of the shielding isolation box 1 to the bottom until the lower end of the mounting seat 4 contacts the bottom of the inner cavity of the shielding isolation box 1.

[0045] Limit slots 41 are symmetrically opened at the left and right of the upper end of the mounting seat 4, and through slots 42 are opened downwardly through the mutually approaching ends of the two limit slots 41. Protruding portions are symmetrically arranged downwardly at the left and right of the lower end of the mounting seat 4.

[0046] Please refer to Figures 6 to 8 , the clamping mechanism includes a bidirectional transmission screw 5 rotatably installed between two protruding portions at the lower end of the mounting seat 4. Knobs 51 are fixedly installed at both ends of the bidirectional transmission screw 5. Round shafts are integrally formed at both ends of the bidirectional transmission screw 5. The round shafts at both ends of the bidirectional transmission screw 5 are rotatably connected to the protruding portions. The two ends of the two round shafts pass through the protruding portions and are fixedly sleeved with the knobs 51. The bidirectional transmission screw 5 has left-handed threads and right-handed threads symmetrically opened at both ends of a round rod. L-shaped transmission plates 52 are symmetrically sleeved on the bidirectional transmission screw 5. The L-shaped transmission plates 52 are threadedly connected to the bidirectional transmission screw 5. The L-shaped transmission plates 52 are slidably connected to the limit slots 41 left and right. The lower ends of the L-shaped transmission plates 52 penetrate downwardly through the through slots 42 and extend to the outside. Clamping plates 53 are fixedly connected to the upper ends of the L-shaped transmission plates 52. Strip-shaped slots 54 are symmetrically opened at the front and rear of the lower ends of the clamping plates 53. Side positioning mechanisms are symmetrically installed at the front and rear ends of the clamping plates 53.

[0047] By rotating the knob 51, the bidirectional transmission screw 5 is driven to rotate. The bidirectional transmission screw 5 drives the two L-shaped transmission plates 52 thereon to approach or separate from each other. The L-shaped transmission plates 52 slide along the limit slots 41 and the through slots 42. At the same time, the two L-shaped transmission plates 52 drive the two clamping plates 53 to approach or separate from each other, so that the clamping plates 53 can clamp or release the network device, and at the same time, the network device with different lengths can be clamped and fixed.

[0048] The side positioning mechanism includes threaded columns 55 symmetrically and fixedly connected to the front and rear ends of the clamping plate 53. An L-shaped clamping block 6 is sleeved on the threaded column 55. A circular hole 61 is vertically penetrated through the front and rear sides of the L-shaped clamping block 6. A rectangular groove 62 is vertically penetrated through the upper end of the L-shaped clamping block 6. The rectangular groove 62 penetrates through the circular hole 61. A threaded sleeve 63 is rotatably connected in the circular hole 61. An adjusting sleeve 64 is fixedly sleeved on the threaded sleeve 63. A strip plate 65 is fixedly connected to the lower end of the side of the L-shaped clamping block 6 close to the clamping plate 53. The strip plate 65 is slidably inserted into and out of the front and rear of the strip groove 54.

[0049] The threaded sleeve 63 is sleeved on the threaded column 55, and the threaded sleeve 63 is threadedly connected to the threaded column 55. The threaded sleeve 63 is rotatably connected to the circular hole 61. The adjusting sleeve 64 is arranged in the rectangular groove 62, and the adjusting sleeve 64 is in rotational contact with the rectangular groove 62. The upper end of the adjusting sleeve 64 passes upward through the rectangular groove 62 and extends to the outside.

[0050] By rotating the adjusting sleeve 64 to drive the threaded sleeve 63 to rotate synchronously, when the threaded sleeve 63 rotates along the threaded column 55, the threaded sleeve 63 moves back and forth along the threaded column 55. At the same time, the threaded sleeve 63 drives the L-shaped clamping block 6 to move back and forth through the adjusting sleeve 64. The L-shaped clamping block 6 drives the strip plate 65 to slide back and forth along the strip groove 54, so as to adjust the distance between the two L-shaped clamping blocks 6 on the front and rear sides of the clamping plate 53, enabling the L-shaped clamping block 6 to clamp network devices of different widths.

[0051] When the clamping plate 53 moves, it drives the L-shaped clamping block 6 to move synchronously through the strip plate 65 and the threaded column 55, so that the L-shaped clamping block 6 is stuck on the front and rear sides of the network device. Through the cooperation of the arranged clamping plate 53 and the L-shaped clamping block 6, the network device can be firmly clamped and fixed, preventing the network device from moving randomly on the mounting seat 4, thereby causing damage to the network device or disconnection from the network cable.

[0052] Please refer to Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 and Figure 12 As shown in, a protective plate 25 is fixedly connected to the front side of the isolation cover 2. The primary locking mechanism includes an isolation plate 7 fixedly installed at the lower end of the isolation cover 2. A lifting groove 71 is recessed upward at the lower end of the isolation plate 7. The two sides of the lifting groove 71 penetrate through the left and right sides of the isolation plate 7. A plurality of sliding grooves 72 are equidistantly penetrated through one inner side wall of the lifting groove 71. The isolation plate 7 is inserted into the docking groove 13;

[0053] The bottom of the docking groove 13 is fixedly connected with an L-shaped base 73. The front side of the L-shaped base 73 extends into the isolation box 16. The side of the L-shaped base 73 contacts the inner side wall of the isolation box 16. The bottom of the L-shaped base 73 contacts the bottom of the inner cavity of the isolation box 16. A plurality of L-shaped first lower card slots are equidistantly arranged on the inner side of the L-shaped base 73. An L-shaped pressing plate 74 is installed above the L-shaped base 73. A plurality of L-shaped first upper card slots are arranged at the lower end and the outer side of the L-shaped pressing plate 74. The number of the L-shaped first upper card slots is the same as that of the L-shaped first lower card slots, and the positions of the L-shaped first upper card slots and the L-shaped first lower card slots are aligned up and down one by one. The bottom of the inner side of the L-shaped pressing plate 74 is fixedly connected with a lifting plate 75. The lifting plate 75 is slidably connected with the lifting groove 71 up and down. A plurality of elastic sheets 76 are equidistantly and fixedly installed at the upper end of the lifting plate 75. The upper end of the elastic sheet 76 abuts against the upper end of the lifting groove 71. A plurality of sliding blocks 77 are equidistantly and fixedly connected to the side of the lifting plate 75. Each sliding block 77 is slidably connected with the adjacent sliding groove 72 up and down.

[0054] When the network cable is thicker, at this time, the lifting plate 75 slides along the lifting groove 71, and at the same time, the lifting plate 75 drives the sliding block 77 to slide along the sliding groove 72, so that the lifting plate 75 can slide stably along the lifting groove 71, preventing the lifting plate 75 from disengaging from the lifting groove 71;

[0055] Through the cooperation of the L-shaped first upper card slot on the L-shaped pressing plate 74 and the L-shaped first lower card slot on the L-shaped base 73, the network cable is clamped and locked to prevent the network cable from loosening; through the elastic sheet 76 arranged in the lifting groove 71, under the action of the elastic force of the elastic sheet 76, it is prevented that the pressure of the L-shaped pressing plate 74 is too large and damages the network cable.

[0056] After the network device is installed, the network cable is clamped into the L-shaped first upper card slot on the L-shaped pressing plate 74. When the isolation cover 2 moves downward, it drives the isolation plate 7 to insert into the docking groove 13. At this time, the isolation plate 7 drives the L-shaped pressing plate 74 to move downward through the lifting plate 75, so that the L-shaped pressing plate 74 pushes the network cable to move downward until the network cable is clamped into the L-shaped first lower card slot on the L-shaped base 73, thus completing the clamping and fixing of the network cable.

[0057] Please refer to Figure 4 、 Figure 5 、 Figure 9 and Figure 12, a concave notch 17 is recessed downward at the upper end of the front side of the isolation box 16. The secondary locking mechanism includes an extension plate 8 fixedly installed at the bottom of the concave notch 17. The upper end surface and the rear side surface of the extension plate 8 are set as a curved surface. A plurality of second lower locking grooves are equidistantly arranged on the curved surface of the extension plate 8. The number of the second lower locking grooves is the same as that of the L-shaped first lower card slots. The second lower locking grooves and the L-shaped first lower card slots are in one-to-one vertical correspondence. An L-shaped locking plate 81 is arranged above the extension plate 8. The inner side of the L-shaped locking plate 81 is a curved surface. The curved surface on the inner side of the L-shaped locking plate 81 matches the curved surface on the extension plate 8. A plurality of second upper locking grooves are equidistantly arranged on the inner side of the L-shaped locking plate 81. The number of the second upper locking grooves is the same as that of the second lower locking grooves, and the positions of the second upper locking grooves and the second lower locking grooves are vertically aligned one by one. Vertical plates 82 are symmetrically and fixedly connected to the left and right of the upper end of the L-shaped locking plate 81. The upper ends of the vertical plates 82 penetrate upward through the protective plate 25. The vertical plates 82 are slidably connected to the protective plate 25 up and down. An adjusting bolt 83 is threadedly installed at the upper end of the protective plate 25. The lower end of the adjusting bolt 83 passes through the protective plate 25 and is rotationally connected to the L-shaped locking plate 81 through a pin shaft.

[0058] When the network cable is connected to the network device, first pass one end of the network cable through the concave notch 17 and the docking groove 13 in sequence, so that one end of the network cable extends above the mounting seat 4, the network cable is above the L-shaped base 73 and the extension plate 8, and at the same time the network cable is below the L-shaped pressing plate 74 and the L-shaped locking plate 81.

[0059] After initially locking the network cable through the primary locking mechanism, the network cable is clamped into the second lower locking groove, and then the adjusting bolt 83 is screwed downward along the protective plate 25. The adjusting bolt 83 drives the L-shaped locking plate 81 to move downward. The L-shaped locking plate 81 drives the vertical plate 82 to slide along the protective plate 25, so that the L-shaped locking plate 81 can move downward stably. After the L-shaped locking plate 81 moves downward for a certain distance, the second upper locking groove on the inner side of the L-shaped locking plate 81 is stuck on the upper end of the network cable. The network cable is further locked and fixed through the cooperation of the second upper locking groove and the second lower locking groove, thereby preventing the network cable from loosening or detaching from the network device, and at the same time being able to neatly arrange the network cables to prevent the network cables from being wound around each other.

[0060] Through the cooperation of the provided shielding isolation box 1 and the isolation cover 2, the network cable device can be well isolated and protected. Through the cooperation of the provided isolation box 16, the protective plate 25 and the isolation plate 7, the position where the network cable enters the shielding isolation box 1 is isolated and protected, so as to realize the comprehensive isolation of the network device.

[0061] Working principle: When installing a network device, first push two push blocks 33 on the connecting blocks 22 on both sides of the shielding isolation box 1 close to each other. The push block 33 drives the circular block 3 to compress the locking spring 32. At the same time, the circular block 3 drives the locking rod 31 to move out of the lower locking hole 15 on the limiting plate 14. At this time, push the connecting block 22 upward. The connecting block 22 drives the isolation cover 2 to move upward through the support plate 21, so that the isolation cover 2 is separated from the shielding isolation box 1. After the isolation cover 2 moves upward for a certain distance, release the pressing on the push block 33.

[0062] When the connecting block 22 moves upward, it drives the convex block 24 to slide upward along the convex groove 11. When the convex block 24 moves to the uppermost end of the convex groove 11, the isolation cover 2 moves upward to the highest position. At this time, under the action of the elastic force of the locking spring 32, the circular block 3 moves outward along the circular groove 23. The circular block 3 drives the locking rod 31 to slide outward along the connecting block 22. At the same time, the locking rod 31 is inserted into the upper locking hole 15 on the limiting plate 14, so that the connecting block 22 and the limiting plate 14 are relatively fixed. The connecting block 22 supports the support plate 21, and the support plate 21 supports the isolation cover 2. At this time, the isolation cover 2 is far away from the upper end of the shielding isolation box 1, making the upper end of the shielding isolation box 1 in an open state, so that operations such as installing or disassembling the network device can be conveniently carried out.

[0063] When the isolation cover 2 moves upward, it drives the mounting seat 4 to move upward through the guide plate 43. When the isolation cover 2 moves upward to the highest position, it drives the mounting seat 4 to move upward from the bottom of the inner cavity of the shielding isolation box 1 to the upper end. At this time, the mounting seat 4 drives the clamping mechanism to move upward out of the shielding isolation box 1.

[0064] Place the network device on the upper end of the mounting seat 4, and at the same time make the network device located between the two clamping plates 53. Rotate the knob 51 to drive the bidirectional transmission screw 5 to rotate. The bidirectional transmission screw 5 drives the two L-shaped transmission plates 52 on it to approach each other. The two L-shaped transmission plates 52 drive the two clamping plates 53 to approach each other, so that the clamping plates 53 clamp the network device.

[0065] When the clamping plate 53 moves, it drives the L-shaped clamping block 6 to move synchronously through the strip plate 65 and the threaded column 55, so that the L-shaped clamping block 6 is stuck on the front and rear sides of the network device. Through the cooperation of the set clamping plate 53 and the L-shaped clamping block 6, the network device can be firmly clamped and fixed to prevent the network device from moving randomly on the mounting seat 4.

[0066] By rotating the adjusting sleeve 64, the threaded sleeve 63 moves back and forth along the threaded post 55. At the same time, the threaded sleeve 63 drives the L-shaped clamping block 6 to move back and forth through the adjusting sleeve 64, thereby adjusting the distance between the two L-shaped clamping blocks 6 on the front and rear sides of the clamping plate 53, enabling the L-shaped clamping blocks 6 to clamp network devices of different widths, so that the clamping mechanism and the side positioning mechanism can clamp and fix network devices of different sizes.

[0067] The connecting end of the network cable is extended to the mounting seat 4 through the concave notch 17 and the docking groove 13 in sequence, so that the connecting end of the network cable is inserted into the interface of the network device, and then the network cable is clamped into the L-shaped first upper card slot on the L-shaped pressing plate 74.

[0068] Then, the two push blocks 33 on the connecting blocks 22 on both sides of the shielding isolation box 1 are pushed closer to each other, so that the locking rod 31 is removed from the upper locking hole 15 on the limiting plate 14. Then, the connecting block 22 is pushed downward. When the connecting block 22 moves downward for a certain distance, the pressing on the push block 33 is released. When the connecting block 22 moves downward, it drives the isolation cover 2 to move downward through the support plate 21 until the lower end of the isolation cover 2 is hermetically connected to the upper end of the shielding isolation box 1. At this time, under the action of the elastic force of the locking spring 32, the locking rod 31 is inserted into the lower locking hole 15 on the limiting plate 14.

[0069] When the isolation cover 2 moves downward, it drives the guide plate 43, the protection plate 25, and the isolation plate 7 to move downward synchronously. The guide plate 43 drives the mounting seat 4 to move downward, and the mounting seat 4 drives the network device to move downward. When the lower end of the isolation cover 2 contacts the upper end of the shielding isolation box 1, the mounting seat 4 drives the network device to move downward to the lowest position;

[0070] When the isolation plate 7 is inserted downward into the docking groove 13, the isolation plate 7 drives the L-shaped pressing plate 74 to move downward through the lifting plate 75, so that the L-shaped pressing plate 74 pushes the network cable downward until the network cable is clamped into the L-shaped first lower card slot on the L-shaped base 73, thereby completing the clamping and fixing of the network cable.

[0071] When the protection plate 25 moves downward, it drives the L-shaped locking plate 81 to move downward through the adjusting bolt 83, so that the L-shaped locking plate 81 is located above the network cable, but at this time the L-shaped locking plate 81 does not clamp and fix the network cable; the network cable is clamped into the second lower locking groove, and then the adjusting bolt 83 is screwed downward along the protection plate 25. The adjusting bolt 83 drives the L-shaped locking plate 81 to move downward. After the L-shaped locking plate 81 moves downward for a certain distance, the second upper locking groove on the inner side of the L-shaped locking plate 81 is stuck on the upper end of the network cable. The network cable is further locked and fixed through the cooperation of the second upper locking groove and the second lower locking groove, thereby preventing loosening or detachment between the network cable and the network device, and at the same time being able to neatly arrange the network cables to prevent entanglement between the network cables.

[0072] The cooperation of the provided shielding isolation box 1 and the isolation cover 2 can well isolate and protect the network cable device. The cooperation of the provided isolation box 16, the protection plate 25 and the isolation plate 7 isolates and protects the position where the network cable enters the shielding isolation box 1, thereby realizing comprehensive isolation of the network device.

[0073] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
