Description

Technical Field

[0001] This utility model is a network security isolation device, belonging to the field of network security isolation devices. Background Technology

[0002] A network security isolation device is a device used to ensure network information security. It isolates different network environments through physical or logical means to prevent unauthorized data exchange and malicious attacks. In existing technologies, when using a network security isolation device, the RJ45 connector on the network cable needs to be inserted into the network interface, and the network is controlled by a firewall to reduce the possibility of viruses invading computers through the network. When the network cable is subjected to a large external force, especially the force along the direction of the network cable, the RJ45 connector can easily come out of the slot. Because the RJ45 connector is made of plastic, when subjected to a large force, the force of the network cable will be concentrated on the transparent spring installed on the RJ45 connector. This can easily cause the transparent spring to deform or break due to excessive local stress, thus losing its restraining function of the RJ45 connector. This can cause the RJ45 connector of the network cable to come out of the slot, affecting data transmission efficiency. Therefore, it is necessary to design a network security isolation device that can reduce the possibility of the RJ45 connector coming out of the slot. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a network security isolation device to solve the problems mentioned in the background technology. This utility model reduces the situation where the RJ45 connector will detach from the insertion slot when the network cable is pulled forcefully, and reduces the damage to the internal sub-wires and pin connections of the RJ45 connector when the network cable is pulled.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a network security isolation device, including a firewall, with multiple indicator lights installed on the front side of the firewall in a linear array, a display screen installed on the front side of the firewall located to the right of the indicator lights, heat dissipation holes symmetrically provided on both sides of the firewall, multiple insertion slots installed on the rear side of the firewall, a fixing ring installed on the outer side of the insertion slots, a fixing structure installed on the side of the fixing ring closer to the firewall, and a rotating column installed on the side of the fixing ring away from the firewall, with a spring-loaded component installed inside the rotating column.

[0005] Furthermore, the fixing structure includes insertion rods, two insertion rods are symmetrically installed on the rear side of the fixing ring, the insertion rods are inserted into the firewall, the two insertion rods are respectively inserted into the two sides of the insertion slot, and a spring is installed on the opposite side of the two insertion rods. A limit slot is opened inside the firewall, and the spring is inserted into the limit slot.

[0006] Furthermore, two cylinders are symmetrically installed on the front side of the firewall, with the two cylinders located on both sides of the fixing ring. A connecting rod is installed on the side of the cylinder closest to the firewall, and the connecting rod is inserted inside the firewall. A spring is installed on the end of the connecting rod outside the firewall, and a push plate is installed on the end of the connecting rod inserted inside the firewall. The push plate is inserted inside the limiting groove, and the bottom of the push plate is in contact with the spring piece.

[0007] Furthermore, the cross-section of the spring is triangular, the cross-section of the fixing ring is U-shaped, the diameter of the spring is smaller than the diameter of the cylinder, and the spring is located on the side of the cylinder closer to the firewall.

[0008] Furthermore, the spring-loaded component includes a positioning plate, which is installed at the bottom of the fixing ring. A central shaft is installed on the side of the positioning plate near the rotating column, and the rotating column is installed on the central shaft.

[0009] Furthermore, a fixing block is installed on the side of the rotating column and the central shaft that are close to each other, and a coil spring is installed between the rotating column and the central shaft, with the two ends of the coil spring respectively installed on the two fixing blocks.

[0010] The beneficial effects of this utility model are as follows: In this network security isolation device, after the RJ45 connector is inserted into the mounting slot, one end of the network cable is inserted into the fixing ring. Then, two symmetrically mounted mounting rods on the fixing ring are inserted into the firewall. When the position of the spring clip matches the position of the limiting slot, the spring clip automatically springs back and engages with the limiting slot, fixing the position of the fixing ring. This restricts the position of the RJ45 connector within the mounting slot, fixes the outer side of the connector, reduces its movement space, and thus reduces the likelihood of the RJ45 connector separating from the mounting slot when the network cable is pulled, improving the stability of the connection between the network cable and the firewall.

[0011] By pressing the cylinders installed on both sides of the fixing ring, the springs installed at the bottom of the cylinders are compressed, thereby pushing the connecting rod into the firewall. The push plate installed at the bottom of the connecting rod then presses the spring piece downward, causing the spring piece to retract into the insert rod, thus releasing the restriction on the position of the fixing ring. This makes it easier to separate the fixing ring from the firewall and remove the crystal head from the insert slot.

[0012] By winding the network cable around the rotating post, when the cable is pulled, the pulling force causes the rotating post to rotate around the central axis, thereby causing the network cable to rotate and release along the rotating post. This reduces the impact on the internal wires and pins of the RJ45 connector when the cable is pulled directly, and reduces the possibility of poor signal contact caused by the wires and pins separating. In addition, a coil spring is installed between the rotating post and the central axis. When the pulling force of the network cable is removed, the coil spring will automatically rebound, thereby causing the network cable to wind around the outside of the rotating post, which will provide cushioning for the next time the network cable is pulled.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-6This utility model provides a technical solution: a network security isolation device, including a firewall 1. Multiple indicator lights 2 are installed on the front side of the firewall 1, arranged in a linear array. A display screen 3 is installed on the front side of the firewall 1, located to the right of the indicator lights 2. Heat dissipation holes 4 are symmetrically provided on both sides of the firewall 1. Multiple insertion slots 5 are installed on the rear side of the firewall 1. A fixing ring 6 is installed on the outer side of the insertion slots 5. A fixing structure is installed on the side of the fixing ring 6 closest to the firewall 1, and a rotating column 7 is installed on the side of the fixing ring 6 furthest from the firewall 1. A spring-loaded component is installed inside the rotating column 7. The connectivity of the network cable installed on the firewall 1 can be observed through the indicator lights 2. When the network cable is connected, the corresponding indicator light 2 will light up, facilitating the observation of the network cable connectivity during later maintenance of the firewall 1.

[0023] Please see Figures 2-4 The fixing structure includes insertion rods 10. Two insertion rods 10 are symmetrically installed on the rear side of the fixing ring 6. The insertion rods 10 are inserted inside the firewall 1. The two insertion rods 10 are respectively inserted on both sides of the insertion slot 5. A spring piece 15 is installed on the opposite side of the two insertion rods 10. A limit groove 14 is opened inside the firewall 1, and the spring piece 15 is inserted inside the limit groove 14. Two cylinders 8 are symmetrically installed on the front side of the firewall 1. The two cylinders 8 are respectively located on both sides of the fixing ring 6. A connecting rod 11 is installed on the side of the cylinder 8 closest to the firewall 1. The connecting rod 11 is inserted inside the firewall 1. A spring piece is installed on the end of the connecting rod 11 outside the firewall 1. A spring 12 and a connecting rod 11 are installed inside the firewall 1. One end of the connecting rod 11 is fitted with a push plate 13, which is inserted into the limiting groove 14. The bottom of the push plate 13 contacts the spring piece 15. The spring piece 15 has a triangular cross-section, and the fixing ring 6 has a U-shaped cross-section. The diameter of the spring 12 is smaller than the diameter of the cylinder 8. The spring 12 is located on the side of the cylinder 8 closest to the firewall 1. With the cooperation of the spring 12, when the cylinder 8 is pressed and then released, the spring 12 rebounds and pushes the cylinder 8 upward, thereby driving the connecting rod 11 to move outward inside the firewall 1, so that the cylinder 8 returns to its original position, making it easier to push the push plate 13 to move its position next time.

[0024] Please see Figure 5 and Figure 6 The spring-loaded component includes a positioning plate 16, which is installed at the bottom of the fixing ring 6. A central shaft 9 is installed on the side of the positioning plate 16 near the rotating column 7. The rotating column 7 is installed on the central shaft 9. Fixing blocks 17 are installed on the sides of the rotating column 7 and the central shaft 9 that are close to each other. A coil spring 18 is installed between the rotating column 7 and the central shaft 9. The two ends of the coil spring 18 are respectively installed on the two fixing blocks 17. Through the cooperation of the fixing blocks 17 and the coil spring 18, the central shaft 9 and the rotating column 7 are connected in series. The force of the coil spring 18 returning to its original position drives the rotating column 7 to rotate, thereby rewinding the network cable onto the rotating column 7.

[0025] Detailed Implementation: After the RJ45 connector is inserted into the mounting slot 5, one end of the network cable is inserted into the retaining ring 6. Then, the two symmetrically mounted mounting rods 10 on the retaining ring 6 are inserted into the firewall 1. When the position of the spring clip 15 matches the position of the limiting slot 14, the spring clip 15 will automatically spring back and engage with the limiting slot 14, fixing the position of the retaining ring 6. This restricts the position of the RJ45 within the mounting slot 5, securing the outer side of the RJ45 and reducing its movement space, thereby reducing the risk of damage when pulling the network cable. When the connector is separated from the mounting slot 5, the stability of the connection between the network cable and the firewall 1 is improved. By pressing the cylinders 8 installed on both sides of the fixing ring 6, the springs 12 installed at the bottom of the cylinders 8 are compressed, thereby pushing the connecting rod 11 into the firewall 1. The push plate 13 installed at the bottom of the connecting rod 11 presses the spring piece 15 downward, thereby retracting the spring piece 15 into the mounting rod 10, releasing the restriction on the position of the fixing ring 6, making it easier to separate the fixing ring 6 from the firewall 1, and thus remove the connector from the mounting slot 5.

[0026] By winding the network cable around the rotating post 7, when the network cable is pulled, the pulling force will cause the rotating post 7 to rotate around the central axis 9, thereby causing the network cable to rotate and release along the rotating post 7. This reduces the impact force on the internal wires and pins of the RJ45 connector when the network cable is pulled directly, and reduces the possibility of poor signal contact caused by the separation of the wires and pins. In addition, a coil spring 18 is installed between the rotating post 7 and the central axis 9. When the pulling force of the network cable is removed, the coil spring 18 will automatically rebound, thereby causing the network cable to be wound around the outside of the rotating post 7, which will facilitate buffering when the network cable is pulled next time.

[0027] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
