Description

Technical Field

[0001] This invention relates to the field of security isolation and protection devices, specifically a security isolation and protection device for computer networks. Background Technology

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. It can perform numerical and logical calculations, and also has storage and memory functions. It is a modern intelligent electronic device capable of running programs and automatically and rapidly processing massive amounts of data. A network is a global internet system formed by multiple computers and other network devices interconnected through communication lines or wireless links. It is a platform for information exchange and resource sharing based on communication technology. The basic components of a network include computers, network devices, and communication lines. Computers are the nodes of the network, connected together through network devices (such as routers and switches). Communication lines are the medium for data transmission, which can be wired (such as fiber optic cables or cables) or wireless (such as wireless LANs or cellular networks). Network protocols are the rules and conventions for implementing data transmission and communication; common network protocols include TCP / IP, HTTP, and FTP protocols. Through these protocols, computers can communicate with each other and exchange data, ensuring the correct transmission and processing of data. Network security includes two aspects: one is physical security, which refers to the protection of tangible items such as communication and computer equipment and related facilities in the network system, preventing them from being exposed to rain, etc.; the other is what we usually call logical security, including information integrity, confidentiality, and availability, etc. Both physical and logical security are very important. If either aspect is not protected, network security will be affected. Therefore, when carrying out security protection, it is necessary to make reasonable arrangements and take both aspects into consideration.

[0003] Chinese patent discloses a computer network information security protection device (authorization announcement number CN215813987U). This patented technology includes a protector body with heat dissipation meshes on both sides. A drive motor is located at the top inside the protector body, with a cooling fan rotatably connected to one end of the drive motor. An information security processor is located inside the protector body, and a data isolation module is located inside the information security processor. A signal transmission terminal is located at the output end of the data isolation module, and a data transmission encryption module is located at the output end of the signal transmission terminal. A data analysis module is located at the output end of the data transmission encryption module. Through the circuit detection module, when the computer connects to the network, to avoid affecting the overall operation of the computer, the circuit detection module can perform pre-circuit testing on the computer, preventing malfunctions during operation.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-18 In this embodiment of the invention, a security isolation and protection device for a computer network includes a security isolation and protection box 1. A mounting handle 2 is fixed to the top of the security isolation and protection box 1. A heat dissipation mesh 3 is provided on the outside of the security isolation and protection box 1. An operation mounting pad 4 is fixed to the outside of the security isolation and protection box 1. An operation mounting button 5 is installed on the outside of the operation mounting pad 4. A switch button 6 is installed on the outside of the security isolation and protection box 1. A power cord stabilizing limit device 7 is fixed to the outside of the security isolation and protection box 1. A network cable support and reinforcement device 8 is fixed to the outside of the security isolation and protection box 1. A power cord body 9 is installed on the outside of the security isolation and protection box 1. A network cable body 10 is connected to the outside of the security isolation and protection box 1. A positioning connection device 11 is provided on the outside of the security isolation and protection box 1.

[0043] The power cord stabilizing and limiting device 7 includes a metal connecting pad 71, a hydraulic push rod 72 fixed to one side of the metal connecting pad 71, a metal mounting post 73 fixed to the outside of the output shaft of the hydraulic push rod 72, a guide mounting block 74 fixed to one end of the metal mounting post 73, a double-sided rack 75 fixed to the outside of the guide mounting block 74, a connecting groove 76 formed on the outside of the metal connecting pad 71, a mounting connecting rod 77 fixed to the top of the metal connecting pad 71, a first gear 78 fixed to the outside of the mounting connecting rod 77, a second gear 79 fixed to the outside of the mounting connecting rod 77, a movable rack 710 meshing with the outside of the first gear 78, a mounting bracket 711 fixed to one side of the movable rack 710, and a connecting bracket fixed to one end of the mounting bracket 711. 712, a protective limiting sleeve 713 is fixed to the outside of the connecting bracket 712, and a limiting protection groove 714 is opened on the outside of the protective limiting sleeve 713. An installation guide groove 717 is opened on the outside of the metal connecting pad 71. A blocking limiting plate 716 is fixed to one end of the movable rack 710. A guide connecting block 715 is fixed to the side of the movable rack 710 near the metal connecting pad 71. The connecting slide groove 76 and the guide mounting block 74 are sliding fit components. The second gear 79 and the double-sided rack 75 mesh with each other. The installation guide groove 717 and the guide connecting block 715 are sliding fit components. A protective shell is fixed to the outside of the metal connecting pad 71. A through hole adapted to the size of the power cord body 9 is opened on the outside of the protective shell. The protective shell is isolated from the safety. The protective housing 1 is fixedly connected. The size of the limiting protection groove 714 is adapted to the size of the power cord body 9. The metal connecting pad 71 and the hydraulic push rod 72 are fixed together by adhesive. One end of the metal mounting post 73 is embedded and fixed inside the guide mounting block 74. The blocking limiting plate 716 and the movable rack 710 are fixed together by adhesive. After the power cord body 9 and the safety isolation protective housing 1 are connected, one end of the connector of the power cord body 9 is inserted into the corresponding mounting hole of the safety isolation protective housing 1. In order to avoid loosening due to accidental pulling or other reasons, the power cord body 9 passes through the outer shell of the metal connecting pad 71. Then the hydraulic push rod 72 on the outer side of the metal connecting pad 71 can be activated. The output shaft of the hydraulic push rod 72 drives the metal... The mounting post 73 moves horizontally, allowing the guide mounting block 74 to move simultaneously. The guide mounting block 74 slides within the connecting groove 76 on the metal connecting pad 71, thus providing guidance. Simultaneously, the movement of the guide mounting block 74 drives the double-sided rack 75 to move, which in turn rotates the second gear 79 meshing with it. Since the second gear 79 is fixedly connected to the mounting connecting rod 77, the mounting connecting rod 77 can simultaneously rotate the first gear 78 fixedly connected to it. The rotation of the first gear 78 then drives the movable rack 710 meshing with it to move horizontally. The limiting plate 716 on the outer side of the movable rack 710 serves as a limiting element.The guide connecting block 715 at the bottom of the movable rack 710 slides within the corresponding mounting guide groove 717, serving a guiding function. After the movable rack 710 moves, it allows the mounting bracket 711 to move, which in turn moves the connecting bracket 712, causing the connecting bracket 712 to move the protective limit sleeve 713 and the limit protection groove 714 together. This allows the limit protection groove 714 to movably engage with the outside of the corresponding power cord body 9, thus reinforcing the connection between the power cord stabilizing limit device 7 and the safety isolation protection box 1. This prevents loosening due to accidental pulling or other reasons, improving the safety isolation protection effect of the computer network.

[0044] In one embodiment of the present invention, the network cable support and reinforcement device 8 includes a support mounting block 81, a reinforcement mounting block 82 fixed to one side of the support mounting block 81, a fixed mounting base 83 fixed to the top of the support mounting block 81, a metal support frame 84 fixed to the top of the fixed mounting base 83, a metal rotating shaft 85 fitted to the outer side of the metal support frame 84, an electric push rod 86 fixed to the top of the metal support frame 84, a lifting metal frame 89 fixed to the top of the output shaft of the electric push rod 86, reinforcement connecting blocks 87 fixed to both sides of the electric push rod 86, mounting holes provided on the outer side of the metal support frame 84, one side of the support mounting block 81 fitting against the outer side of the safety isolation protection box 1, and the reinforcement connecting blocks 87 and the metal support frame 84... The metal support frame 84 is welded and fixed together with the metal frame 89. A mounting connection hole 88 is provided on the outer side of the metal support frame 84. Both ends of the lifting metal frame 89 are rotatably connected to a first rotating shaft 812. A rotating metal arm 810 is fixed to the outer side of the first rotating shaft 812. A connecting groove 811 is provided inside the rotating metal arm 810, the size of which matches the size of the lifting metal frame 89. A second reference shaft 813 is fitted onto the rotating metal arm 810. A support sleeve 814 is rotatably connected to the rotating metal arm 810 via the second reference shaft 813. A mounting groove 815 is provided inside the rotating metal arm 810, the size of which matches the size of the support sleeve 814. A reinforcing mounting block 82 is embedded and fixed in the safety isolation protection box. Inside body 1, the metal support frame 84 and the fixed mounting base 83 are fixedly connected by bolts. An arc-shaped groove is provided on the outer side of the supporting sleeve 814, and this arc-shaped groove fits snugly against the outer side of the network cable body 10. One end of the network cable body 10 is provided with a network cable connector, and the outer side of the safety isolation protection box 1 is provided with a network cable socket. When the network cable body 10 and the safety isolation protection box 1 are connected, one end of the network cable body 10 is inserted into the corresponding network cable socket in the safety isolation protection box 1. The reinforcing mounting block 82 on the outer side of the supporting mounting block 81 is embedded and fixed inside the safety isolation protection box 1, ensuring a stable and secure connection between the supporting mounting block 81 and the safety isolation protection box 1. Then, the top of the metal support frame 84 can be activated. The electric push rod 86, after being started, can drive the lifting metal frame 89 to move vertically through the output shaft, so that the lifting metal frame 89 pushes one end of the rotating metal arm 810. The rotating metal arm 810 and the metal support frame 84 are rotatably connected by the first rotating shaft 812, so the rotating metal arm 810 can be pushed and rotated by the lifting metal frame 89. When the other end of the rotating metal arm 810 rotates, it can drive the support sleeve 814 to move, so that the corresponding surface of the support sleeve 814 fits against the outside of the network cable body 10, thereby facilitating the reinforcement of the outside after the network cable body 10 is connected to the safety isolation protection box 1. Moreover, the operation of removing the reinforcement is also relatively convenient, which can adapt to the plugging and unplugging needs of the network cable body 10.

[0045] In one embodiment of the present invention, the positioning connection device 11 includes a guide metal plate 111. A guide mounting groove 112 is provided on the outer side of the guide metal plate 111. A sliding connecting block 113 is slidably connected to the guide metal plate 111 through the guide mounting groove 112. A plastic handle plate 114 is fixed to the outer side of the sliding connecting block 113. A movable mounting sleeve 115 is fixed to the outer side of the sliding connecting block 113. A fixing metal block 116 is fixed to the outer side of the protective shell of the power cord stabilizing limit device 7. A limit mounting sleeve 117 is installed on the outer side of the fixing metal block 116. A positioning connection is provided on the outer side of the movable mounting sleeve 115. A positioning groove 118 is provided. A positioning threaded rod 119 is fixed to the outside of the fixing metal block 116. A washer 1110 is movably sleeved on the outside of the positioning threaded rod 119. A positioning threaded sleeve 1111 is threadedly connected to the outside of the positioning threaded rod 119. The outside of the positioning threaded sleeve 1111 is provided with anti-slip texture. One side of the positioning threaded sleeve 1111 fits against the outside of the washer 1110. A guide metal plate 111 is fixedly connected to the safety isolation protection box 1. The outside of the plastic handle plate 114 is provided with diagonal grooves. The plastic handle plate 114 is bonded and fixed to the sliding connecting block 113. A limit mounting sleeve 1 is provided. The interior of the 17 has a groove that matches the size of the movable mounting sleeve 115. After the outer shell of the power cord stabilizing limit device 7 and the safety isolation protection box 1 are fixedly connected, a fixing metal block 116 is fixed on the outer shell of the power cord stabilizing limit device 7. The user can turn the plastic handle plate 114 to move the sliding connecting block 113. The sliding connecting block 113 can slide in the guide mounting groove 112 opened in the corresponding guide metal plate 111, and the movable mounting sleeve 115 on one side of the sliding connecting block 113 can move horizontally, allowing the movable mounting sleeve 115 to move. The movable mounting sleeve 115 is sleeved on the outside of the positioning threaded rod 119. One end of the movable mounting sleeve 115 is movably inserted into the limiting mounting sleeve 117. After the movable mounting sleeve 115 is movably sleeved on the outside of the positioning threaded rod 119, the gasket 1110 can be movably sleeved on the outside of the positioning threaded rod 119. The threaded sleeve 1111 is threadedly connected to the positioning threaded rod 119. The corresponding surface of the positioning threaded sleeve 1111 fits against the outside of the gasket 1110, thereby facilitating the fixation of the movable mounting sleeve 115 and the fixed metal block 116. This can improve the connection stability of the outer shell of the safety isolation protection box 1 and the power cord stabilizing limit device 7.

[0046] The working principle of this invention is as follows: This device is equipped with a power cord stabilizing limit device 7. After the power cord body 9 and the safety isolation protection box 1 are connected, one end of the power cord body 9 is inserted into the corresponding mounting hole in the safety isolation protection box 1. To prevent loosening due to accidental pulling or other reasons, the power cord body 9 passes through the outer shell of the metal connecting pad 71. Then, the hydraulic push rod 72 on the outer side of the metal connecting pad 71 can be activated. The output shaft of the hydraulic push rod 72 drives the metal mounting column 73 to move horizontally. When the metal mounting column 73 moves horizontally, the guide mounting block 74 can move simultaneously. The guide mounting block 74 can slide in the connecting groove 76 opened in the metal connecting pad 71, thereby realizing the guiding function. At the same time, when the guide mounting block 74 moves, it can drive the double-sided rack 75 to move. After the double-sided rack 75 moves, it drives the second gear 79 meshing with it to rotate. Since the second gear 79 and the safety isolation protection box 1 are connected, the power cord body 9 passes through the outer shell of the metal connecting pad 71. Then, the hydraulic push rod 72 on the outer side of the metal connecting pad 71 can be activated. The output shaft of the hydraulic push rod 72 drives the metal mounting column 73 to move horizontally. When the metal mounting column 73 moves horizontally, the guide mounting block 74 can move simultaneously. The guide mounting block 74 can slide in the connecting groove 76 opened in the metal connecting pad 71, thereby realizing the guiding function. At the same time, when the guide mounting block 74 moves, it can drive the double-sided rack 75 to move. After the double-sided rack 75 moves, it drives the second gear 79 meshing with it to rotate. The connecting rods 77 are fixedly connected. The connecting rods 77 can drive the first gear 78 fixedly connected to them to rotate simultaneously. After the first gear 78 rotates, it can drive the movable rack 710 meshing with it to move horizontally. The blocking and limiting plate 716 on the outside of the movable rack 710 plays a limiting role. The guide connecting block 715 at the bottom of the movable rack 710 slides in the corresponding mounting guide groove 717, which plays a guiding role. After the movable rack 710 moves, the mounting bracket 711 can drive the connecting bracket 712 to move, and the connecting bracket 712 can drive the protective limiting sleeve 713 and the limiting protection groove 714 to move together, so that the limiting protection groove 714 can be movably sleeved on the outside of the corresponding power cord body 9, thereby completing the reinforcement between the connection part of the power cord stabilizing limiting device 7 and the safety isolation protection box 1, avoiding loosening due to accidental pulling or other reasons, and improving the safety isolation protection effect of the computer network.This device is equipped with a network cable support and reinforcement device 8. After the network cable body 10 and the safety isolation protection box 1 are connected, one end of the network cable body 10 is inserted into the corresponding network cable interface in the safety isolation protection box 1. The reinforcement mounting block 82 on the outside of the support mounting block 81 is embedded and fixed in the safety isolation protection box 1, which can ensure that the connection between the support mounting block 81 and the safety isolation protection box 1 is stable and does not loosen. Then, the electric push rod 86 on the top of the metal support frame 84 can be activated. After the electric push rod 86 is activated, it can drive the lifting metal frame 89 to move vertically through the output shaft, so that the lifting metal frame 89 pushes one end of the rotating metal arm 810 to rotate. The metal arm 810 and the metal support frame 84 are rotatably connected via the first rotating shaft 812. Therefore, the rotating metal arm 810 can be pushed and rotated by the lifting metal frame 89. When the other end of the rotating metal arm 810 rotates, it can drive the supporting sleeve 814 to move, allowing the corresponding surface of the supporting sleeve 814 to fit against the outside of the network cable body 10. This facilitates the reinforcement of the outside of the network cable body 10 after it is connected to the safety isolation protection box 1. Furthermore, the operation of removing the reinforcement is also relatively convenient, adapting to the plugging and unplugging requirements of the network cable body 10. This avoids loosening and damage caused by pulling or other reasons, extending the service life of the device and facilitating calculations. The device is equipped with a positioning connection device 11. After the outer shell of the power cord stabilizing limit device 7 and the safety isolation protection box 1 are fixedly connected, a fixed metal block 116 is fixed on the outer shell of the power cord stabilizing limit device 7. The user can turn the plastic handle plate 114 to move the sliding connecting block 113. The sliding connecting block 113 can slide in the guide mounting groove 112 opened in the corresponding guide metal plate 111, and the movable mounting sleeve 115 on one side of the sliding connecting block 113 can move horizontally, so that the movable mounting sleeve 115 can be movably sleeved on the positioning threaded rod. On the outside of 119, one end of the movable mounting sleeve 115 is movably inserted into the limiting mounting sleeve 117. After the movable mounting sleeve 115 is movably fitted onto the outside of the positioning threaded rod 119, the gasket 1110 can be movably fitted onto the outside of the positioning threaded rod 119, and the threaded sleeve 1111 is threadedly connected to the positioning threaded rod 119. The corresponding surface of the positioning threaded sleeve 1111 fits against the outer side of the gasket 1110, thereby facilitating the fixation of the movable mounting sleeve 115 and the fixed metal block 116. This improves the connection stability between the safety isolation protection box 1 and the outer shell of the power cord stabilizing limit device 7, ensuring that the power cord stabilizing limit device 7 is assembled stably and does not loosen.
