Description

Technical Field

[0001] This invention relates to the field of network isolation device technology, and in particular to a protective device for network isolation devices and its usage method. Background Technology

[0002] Network isolation devices are core equipment for ensuring network security. By isolating internal and external networks and controlling access permissions, they effectively resist external attacks and malware intrusions. They are widely used in scenarios with stringent security requirements, such as enterprise computer rooms, data centers, and government networks. The stability of the interface and transmission line connection of such devices directly determines the continuity of data transmission and the reliability of network security protection.

[0003] However, existing network isolation devices have key problems in practical use: the transmission line is only connected to the device interface through a connector and lacks a dedicated fixed protective structure. Under conditions such as daily maintenance, equipment movement or environmental vibration, the transmission line is easily pulled and shaken. After long-term use, the connector and interface may become loose or even fall off, which not only causes data transmission interruption and network lag, but may also cause security vulnerabilities due to abnormal connection, posing potential risks to the network system.

[0004] Therefore, it is necessary to provide a protective device for network isolation devices and its usage method to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a protective device for network isolation devices and its usage method, which solves the problems of existing network isolation devices' transmission lines lacking fixed protection and being prone to loosening and falling off.

[0006] To solve the above-mentioned technical problems, the present invention provides a protective device for a network isolation device, comprising:

[0007] The isolation device itself;

[0008] A protective shell is disposed on the outer side of the isolation device body;

[0009] A limiting component is provided on the back of the protective shell. The limiting component includes a limiting frame, which is fixedly installed on the back of the protective shell. The top and bottom of the inner side of the limiting frame are provided with snap-fit ​​grooves.

[0010] A clamping assembly is disposed on the inner side of the limiting frame. The clamping assembly includes a first clamping plate with a groove on its top and first grooves on both sides of the inner side of the groove. A second clamping plate is disposed on the top of the first clamping plate. A movable plate is slidably connected to the bottom of the second clamping plate. Springs are fixedly installed at both ends of the top of the movable plate. Multiple second limiting grooves are formed on the bottom of the movable plate, and the multiple first limiting grooves and multiple second limiting grooves correspond to each other. A snap-fit ​​block is fixedly installed on the bottom of the first clamping plate and the top of the second clamping plate, and two snap-fit ​​blocks are respectively snapped into the inner sides of two snap-fit ​​grooves.

[0011] Preferably, the limiting component further includes a stop bar, which is fixedly installed on the inner side of the limiting frame.

[0012] Preferably, the clamping assembly further includes two positioning rods and two positioning holes. The two positioning rods are respectively fixedly installed at both ends of the top of the first clamping plate, and the two positioning holes are respectively opened inside both ends of the second clamping plate. The two positioning rods and the two positioning holes are compatible with each other.

[0013] Preferably, the bottom of the movable plate is adapted to the inner side of the groove.

[0014] Preferably, multiple adhesive strips are provided on both sides of the protective shell.

[0015] Preferably, the clamping assembly is disposed at the interface on the back of the isolation device body.

[0016] Preferably, a base plate is fixedly installed on all four sides of the bottom of the protective shell, and threaded rods are provided inside the four base plates. Threaded holes are provided on all four sides of the bottom of the isolation device body.

[0017] Preferably, the tops of the four threaded rods are respectively threaded to the inner sides of the four threaded holes, for mounting the isolation device body on the inner side of the protective shell.

[0018] Preferably, a pad is fixedly installed at the bottom of each of the four threaded rods, and a rubber pad is fixedly installed at the bottom of each of the four pads.

[0019] To address the above problems, the present invention also provides a method for using a protective device for a network isolation device, comprising the following steps:

[0020] S1. First, place the isolation device body on the inner side of the protective shell, align the threaded holes around the bottom of the isolation device body with the threaded rods inside the bottom plate of the protective shell, rotate the pad to drive the threaded rods into the threaded holes until the top of the pad is tightly fitted with the bottom plate. The isolation device body is stably installed by symmetrically fixing the four threaded rods. At this time, the rubber pad at the bottom of the pad is in contact with the placement surface, which plays a role in anti-slip and shock absorption.

[0021] S2. When using the device, first insert the connector of the transmission line into the interface on the back of the isolation device body through the limiting frame. Then, place the bodies of multiple transmission lines on the inner sides of multiple first limiting slots. Next, place the second clamping plate on top of the first clamping plate. At this time, the moving plate is inserted into the inner side of the groove, and the positioning rod on the top of the first clamping plate is inserted into the positioning hole of the second clamping plate to achieve precise positioning. At this time, the first and second limiting slots cooperate to form a clamping space for the transmission line. Then, place the first and second clamping plates together into the inner side of the limiting frame. After the user releases their hands, the two springs generate opposite elastic forces, pushing the first and second clamping plates in opposite directions, so that the two snap-fit ​​blocks are snapped into the inner sides of the two snap-fit ​​slots respectively. At the same time, the stop bar forms a front limit on the clamping assembly, thereby firmly restricting the first and second clamping plates to the inner side of the limiting frame, completing the fixation of the transmission line.

[0022] S3. During device operation, the protective shell provides all-round physical protection for the isolation device body, avoiding damage to the equipment caused by external collisions and squeezing; the clamping assembly, through the clamping action of the first limiting groove and the second limiting groove, prevents the connector from loosening or falling off due to pulling or shaking of the transmission line, ensuring the stability of data transmission.

[0023] S4. When it is necessary to disassemble the transmission line or maintain the equipment, press the first clamping plate and the second clamping plate to compress the spring and disengage the snap-fit ​​block from the snap-fit ​​groove. Then, the clamping assembly can be removed from the limit frame. After that, separate the first clamping plate and the second clamping plate to pull out the transmission line connector. If it is necessary to disassemble the isolation device body, rotate the pad in the opposite direction to disengage the threaded rod from the threaded hole. Then, the isolation device body can be removed from the protective shell for cleaning, maintenance or replacement.

[0024] Compared with related technologies, the protective device for network isolation devices and its usage method provided by the present invention have the following beneficial effects:

[0025] This invention provides a protective device for network isolation equipment and its usage method. Through the cooperation of limiting components and clamping components, the transmission line is placed between the first and second limiting slots during use. The reverse elastic force of the spring pushes the first and second clamping plates apart and causes the moving plate to move downwards, allowing the snap-fit ​​block to snap into the snap-fit ​​slot for secure fixation. This clamping protection prevents the transmission line from being pulled or shaken during routine maintenance, equipment movement, or environmental vibrations, preventing loosening or even detachment of connectors and interfaces, ensuring continuous data transmission, avoiding network lag, and reducing security vulnerabilities caused by connection abnormalities.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] First Embodiment

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a protective device for a network isolation device provided by the present invention; Figure 2 for Figure 1 The diagram shows the structure of the limiting component. Figure 3 for Figure 1 The diagram shows the structure of the clamping assembly. Figure 4 for Figure 3 The diagram shows the structure of the first clamping plate. Figure 5 for Figure 3 The diagram shows a cross-sectional view of the second clamping plate.

[0038] A protective device for a network isolation device includes: an isolation device body 1;

[0039] Protective shell 2, the protective shell 2 is disposed on the outer side of the isolation device body 1;

[0040] Limiting component 3 is disposed on the back of the protective shell 2. The limiting component 3 includes a limiting frame 31, which is fixedly installed on the back of the protective shell 2. The top and bottom of the inner side of the limiting frame 31 are provided with snap-fit ​​grooves 33.

[0041] A clamping assembly 4 is disposed on the inner side of the limiting frame 31. The clamping assembly 4 includes a first clamping plate 41, a groove 42 is provided on the top of the first clamping plate 41, and first grooves 43 are provided on both sides of the inner side of the groove 42. A second clamping plate 46 is provided on the top of the first clamping plate 41. A movable plate 48 is slidably connected to the bottom of the second clamping plate 46. Springs 40 are fixedly installed at both ends of the top of the movable plate 48. A plurality of second limiting grooves 49 are provided on the bottom of the movable plate 48. The plurality of first limiting grooves 43 and the plurality of second limiting grooves 49 correspond to each other. A snap-fit ​​block 45 is fixedly installed on the bottom of the first clamping plate 41 and the top of the second clamping plate 46. Two snap-fit ​​blocks 45 are respectively snapped into the inner side of two snap-fit ​​grooves 33.

[0042] The limiting component 3 also includes a stop bar 32, which is fixedly installed on the inner side of the limiting frame 31.

[0043] The protective shell 2 is made of high-strength material, which forms all-round physical protection for the isolation device body 1 and blocks external collisions and squeezing; the limiting frame 31 provides installation and limiting space for the clamping component 4, and the snap-fit ​​groove 33 cooperates with the snap-fit ​​block 45 to realize the quick fixation of the clamping component 4; the stop bar 32 plays a forward limiting role for the clamping component 4, preventing it from extending too far into the limiting frame 31, ensuring that the clamping component 4 is accurately positioned and does not affect the connection between the transmission line connector and the interface of the isolation device body 1.

[0044] The clamping assembly 4 also includes two positioning rods 44 and two positioning holes 47. The two positioning rods 44 are respectively fixedly installed at both ends of the top of the first clamping plate 41, and the two positioning holes 47 are respectively opened inside both ends of the second clamping plate 46. The two positioning rods 44 and the two positioning holes 47 are compatible with each other.

[0045] The first clamping plate 41 and the second clamping plate 46 cooperate to form a clamping structure. The first limiting groove 43 and the second limiting groove 49 are both arc-shaped grooves, which are adapted to the transmission line body to realize the classified clamping and fixing of multiple transmission lines. The positioning rod 44 and the positioning hole 47 are inserted to ensure that the first clamping plate 41 and the second clamping plate 46 are accurately aligned, and to avoid the limiting groove misalignment affecting the clamping effect. The spring 40 provides the first clamping plate 41 and the second clamping plate 46 with a reverse elastic force, so that the two fit tightly together and enhance the clamping force on the transmission line.

[0046] The bottom of the movable plate 48 is adapted to the inner side of the groove 42.

[0047] The adaptive design of the movable plate 48 and the groove 42 ensures that the movable plate 48 can be stably embedded in the groove 42, so that the first clamping plate 41 and the second clamping plate 46 are tightly connected.

[0048] Multiple adhesive strips 21 are provided on both sides of the protective shell 2.

[0049] Multiple rubber strips 21 are installed on the side of the protective shell 2, which can play a buffering role when subjected to external impact.

[0050] The clamping component 4 is located at the interface on the back of the isolation device body 1.

[0051] The clamping component 4 is positioned close to the interface, which can fix the transmission line body in the shortest distance, minimize the force of the transmission line pulling on the connector at the interface, and effectively prevent the connector from loosening and falling off.

[0052] The working principle of the protective device for network isolation provided by this invention is as follows:

[0053] When installing the transmission line, first insert the transmission line connector into the interface on the back of the isolation device body 1, then place each transmission line body into the first limiting groove 43 of the first clamping plate 41, align the second clamping plate 46 with the first clamping plate 41, so that the positioning rod 44 is inserted into the positioning hole 47, and the moving plate 48 is embedded in the groove 42. At this time, the spring 40 is compressed and stored.

[0054] After the assembled clamping assembly 4 is placed into the limiting frame 31, and both hands are released, the spring 40 releases the reverse elastic force, pushing the first clamping plate 41 and the second clamping plate 46 to separate in opposite directions. The top snap-fit ​​block 45 snaps into the snap-fit ​​groove 33 at the top of the limiting frame 31, and the bottom snap-fit ​​block 45 snaps into the bottom snap-fit ​​groove 33. At the same time, the stop strip 32 prevents the clamping assembly 4 from moving forward, thus achieving a stable fixation of the clamping assembly 4. At this time, the first limiting groove 43 and the second limiting groove 49 are tightly attached to the transmission line body to form a firm clamp and prevent the transmission line from shaking or being pulled.

[0055] When disassembling the transmission line, press the first clamping plate 41 and the second clamping plate 46 towards the middle to compress the spring 40, causing the snap block 45 to disengage from the snap groove 33, and the clamping assembly 4 can be removed from the limiting frame 31; separate the first clamping plate 41 and the second clamping plate 46 to release the clamping of the transmission line, and the transmission line connector can be easily pulled out.

[0056] Compared with related technologies, the protective device for network isolation provided by the present invention has the following beneficial effects:

[0057] Through the cooperation of the limiting component 3 and the clamping component 4, the transmission line is placed between the first limiting groove 43 and the second limiting groove 49 during use. The reverse elastic force of the spring 40 pushes the first clamping plate 41 and the second clamping plate 46 to separate and causes the moving plate 48 to move downward, so that the snap-fit ​​block 45 snaps into the snap-fit ​​groove 33 to achieve a stable fixation and form a clamping protection for the transmission line. This prevents the transmission line from being pulled or shaken during daily maintenance, equipment movement or environmental vibration, prevents the connectors and interfaces from loosening or even falling off, ensures the continuity of data transmission, avoids network lag, and reduces security vulnerabilities caused by abnormal connections.

[0058] Second Embodiment

[0059] Please refer to the following: Figure 6 , Figure 7 and Figure 8 Based on the protective device for a network isolation device provided in the first embodiment of this application, the second embodiment of this application proposes another protective device for a network isolation device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0060] Specifically, the second embodiment of this application provides a protective device for a network isolation device, which differs in that the protective device for a network isolation device has a base plate 5 fixedly installed on all four sides of the bottom of the protective shell 2, and threaded rods 51 are provided inside the four base plates 5. Threaded holes 6 are opened on all four sides of the bottom of the isolation device body 1.

[0061] The tops of the four threaded rods 51 are respectively threaded to the inner sides of the four threaded holes 6, for mounting the isolation device body 1 on the inner side of the protective shell 2.

[0062] Each of the four threaded rods 51 has a pad 52 fixedly installed at its bottom, and each of the four pads 52 has a rubber pad 53 fixedly installed at its bottom.

[0063] The working principle of the protective device for network isolation provided by this invention is as follows:

[0064] When installing the isolation device body 1, place it inside the protective shell 2 and align the threaded holes 6 around the bottom with the threaded rods 51 inside the base plate 5; rotate the pad 52 to drive the threaded rods 51 into the threaded holes 6 until the top of the pad 52 is tightly fitted with the base plate 5. The isolation device body 1 is stably installed through the four symmetrically distributed threaded rods 51 to prevent the equipment from shaking inside the protective shell 2.

[0065] At this time, the rubber pad 53 at the bottom of the pad 52 is in contact with the placement surface (such as the computer room cabinet or desktop). The elastic material of the rubber pad 53 plays an anti-slip role, preventing the entire device from sliding. At the same time, it can buffer the impact of environmental vibration on the isolation device body 1, further protecting the equipment.

[0066] When disassembling the isolation device body 1, rotate the pad 52 in the opposite direction to disengage the threaded rod 51 from the threaded hole 6, and then remove the isolation device body 1 from the protective shell 2 for cleaning, maintenance or replacement.

[0067] Compared with related technologies, the protective device for network isolation provided by the present invention has the following beneficial effects:

[0068] The structure, including the base plate 5, threaded rod 51, pad 52, rubber pad 53, and threaded hole 6 at the bottom of the isolation device body 1, works together to rotate the pad 52 to drive the threaded rod 51 into the threaded hole 6 during use, thus achieving a stable installation of the isolation device body 1 within the protective shell 2 and preventing the entire device from shaking. At the same time, the rubber pad 53 contacts the placement surface, providing anti-slip and shock absorption, further reducing the impact of environmental vibration on the isolation device body 1.

[0069] To address the above problems, the present invention also provides a method for using a protective device for a network isolation device, comprising the following steps:

[0070] S1. First, place the isolation device body 1 on the inner side of the protective shell 2, align the threaded holes 6 around the bottom of the isolation device body 1 with the threaded rods 51 in the bottom plate 5 of the protective shell 2, rotate the pad 52 to drive the threaded rods 51 into the threaded holes 6 until the top of the pad 52 is tightly attached to the bottom plate 5. The isolation device body 1 is stably installed by symmetrically fixing the four threaded rods 51. At this time, the rubber pad 53 at the bottom of the pad 52 is in contact with the placement surface, which plays a role in anti-slip and shock absorption.

[0071] S2. In use, first insert the connector of the transmission line into the interface on the back of the isolation device body 1 through the limiting frame 31. Then, place the bodies of multiple transmission lines on the inner sides of multiple first limiting grooves 43 respectively. Then, place the second clamping plate 46 on top of the first clamping plate 41. At this time, the moving plate 48 is inserted into the inner side of the groove 42, and the positioning rod 44 on the top of the first clamping plate 41 is inserted into the positioning hole 47 of the second clamping plate 46 to achieve precise positioning. At this time, the first limiting groove 43 and the second limiting groove 49 are matched. The first clamping plate 41 and the second clamping plate 46 are then placed together into the inner side of the limiting frame 31. After the user releases his hands, the two springs 40 generate opposing elastic forces, pushing the first clamping plate 41 and the second clamping plate 46 in opposite directions, so that the two snap-fit ​​blocks 45 respectively snap into the inner side of the two snap-fit ​​slots 33. At the same time, the stop bar 32 forms a front limit on the clamping assembly 4, thereby firmly restricting the first clamping plate 41 and the second clamping plate 46 to the inner side of the limiting frame 31, thus completing the fixation of the transmission line.

[0072] S3. During device operation, the protective shell 2 provides all-round physical protection for the isolation device body 1, preventing damage to the equipment from external collisions and squeezing; the clamping assembly 4, through the clamping action of the first limiting groove 43 and the second limiting groove 49, prevents the connector from loosening or falling off due to pulling or shaking of the transmission line, thus ensuring the stability of data transmission.

[0073] S4. When it is necessary to disassemble the transmission line or maintain the equipment, press the first clamping plate 41 and the second clamping plate 46 to compress the spring 40 and disengage the snap-fit ​​block 45 from the snap-fit ​​groove 33. Then the clamping assembly 4 can be removed from the limiting frame 31. After that, separate the first clamping plate 41 and the second clamping plate 46 to pull out the transmission line connector. If it is necessary to disassemble the isolation device body 1, rotate the pad 52 in the opposite direction to disengage the threaded rod 51 from the threaded hole 6. Then the isolation device body 1 can be removed from the protective shell 2 for cleaning, maintenance or replacement.

[0074] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
