Description

Technical Field

[0001] This application relates to the field of network security protection devices, and in particular to a network security protection device with physical port locking and abnormal access blocking. Background Technology

[0002] In today's era of widespread network technology, the physical ports of network devices, as critical nodes for data transmission and device connections, are directly related to the stability and data security of the network system. Existing network devices generally lack reliable physical locking mechanisms for their physical ports, making them vulnerable to unauthorized access to external devices, leading to security risks such as network data leaks, malicious attacks, and device compromise.

[0003] Some existing protection devices can only achieve a single locked state and cannot flexibly adjust the locking level according to actual usage scenarios (such as temporary opening, limiting the number of accesses, etc.), resulting in poor practicality. At the same time, physical ports are exposed to the outside for a long time, which can easily accumulate dust and debris, affecting the contact performance between the port and the connecting cable, shortening the service life of the equipment, and further reducing the stability of network operation. Utility Model Content

[0004] To address the above issues, this application provides a network security protection device with physical port locking and abnormal access blocking.

[0005] The network security protection device with physical port blocking and abnormal access blocking provided in this application adopts the following technical solution: A network security protection device with physical port locking and abnormal access blocking includes: a housing with a rectangular socket on its front for exposing the network interface to be protected; an inner housing installed inside the housing; a slide groove formed along the length of the inner housing on its top surface; a locking tongue body slidably installed inside the slide groove; and a multi-position locking mechanism installed on the housing for driving the locking tongue body to switch between different locking positions.

[0006] Preferably, the multi-position locking mechanism includes an internally threaded sleeve rod, which is embedded in the front of the housing; The rotating rod is horizontally inserted inside the internal threaded sleeve rod, with its two ends connected to the two ends of the internal threaded sleeve rod via bearings, and its middle part threadedly connected to the internal threaded sleeve rod. Gear, fitted onto the extended end of the rotating rod that extends into the housing; The second limiting plate is fitted onto the extension end of the rotating rod that extends to the outside of the housing.

[0007] Preferably, it also includes a guide rod, which is vertically installed at the center of the top surface of the latch body, with its top end penetrating through the top of the outer shell and extending upward to be connected to a first limiting plate; A toothed plate is installed on the side of the guide rod opposite to the gear and is meshed with the gear.

[0008] Preferably, the multi-position locking mechanism further includes a position adjusting component; A dust cover is fitted over the outside of the gear adjustment component. One end of the dust cover is connected to the front of the outer casing, and the other end is hinged to a dust cover via a lock body.

[0009] Preferably, the gear adjustment component includes a circular plate, which is sleeved on the outer wall of the internally threaded sleeve rod; Multiple position markings are engraved on the side of the circular plate opposite to the second limiting plate.

[0010] Preferably, it also includes a disc, which is sleeved on the outer wall of the rotating rod between the internally threaded sleeve and the second limiting plate; The gear slots are located on the edge of the disc and correspond one-to-one with the gear numbers.

[0011] Preferably, it also includes a connecting circular plate, which is sleeved on the outer wall of the rotating rod between the disc and the second limiting plate; A gear shift plate is installed on the side of the connecting circular plate opposite to the disc, and is adapted to the gear shift slot; A lever is installed on the outer wall of the connecting circular plate.

[0012] Preferably, it also includes baffles, two of which are symmetrically arranged on the side of the disk opposite to the connecting plate; The two baffles correspond to the gear slots respectively.

[0013] In summary, this application includes the following beneficial technical effects: Using a lever as the operating end, the device unlocks by axial movement and starts by circumferential rotation. Through multi-stage transmission via the screw thread and gear teeth, the rotational power is converted into linear displacement of the locking tongue.

Combined with dustproof and limiting structures, the device ensures convenient operation, stable operation, and long service life. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0017] This application discloses a network security protection device with physical port locking and abnormal access blocking, referring to... Figure 1 and Figure 2 It includes an outer shell 1, which is a hollow rectangular structure and serves as the external protective carrier of the device. The rectangular socket 11 on its front is adapted to the position and size of the network interface to be protected, so as to expose the network interface for easy access operation. The inner shell 7 is fixedly installed inside the outer shell 1 and fits against the inner wall of the outer shell 1, providing a stable installation support base for the locking tongue body 2.

[0018] The slide groove 3 is formed on the top surface along the length of the inner shell 7. The size of the locking tongue body 2 is adapted to the slide groove 3 and is slidably assembled in the slide groove 3. It can move back and forth along the slide groove 3 to block or avoid the rectangular socket 11, thereby achieving the purpose of locking or opening the network interface. In addition, the inner side wall of the slide groove 3 is provided with a wear-resistant coating to reduce the friction loss when the locking tongue body 2 slides and ensure smooth adjustment.

[0019] Reference Figure 2 and Figure 4 The multi-position locking mechanism is used to drive the locking tongue body 2 to move and achieve position fixation. It includes an internal threaded sleeve 13, which is embedded in the mounting hole on the front of the housing 1 and fixed by welding. The rotating rod 12 is horizontally inserted inside the internal threaded sleeve 13, and its two ends are rotatably connected to the two ends of the internal threaded sleeve 13 through bearings. The external thread in the middle of the rotating rod 12 is adapted to the internal thread of the internal threaded sleeve 13. When the rotating rod 12 is rotated, it can achieve its own axial rotation. The gear 4 is fixedly sleeved on the end of the rotating rod 12 that extends into the housing 1 by a flat key and rotates synchronously with the rotating rod 12. The second limiting plate 18 is fixedly sleeved on the end of the rotating rod 12 that extends into the housing 1 and is used to limit the axial movement range of the connecting round plate 17 and prevent the connecting round plate 17 from detaching from the rotating rod 12.

[0020] It also includes a guide rod 5, which is vertically welded to the center of the top surface of the latch body 2. Its top end passes through the through hole opened at the top of the outer shell 1 and extends upward. A first limiting plate 6 is fixedly connected to the top end. The diameter of the first limiting plate 6 is larger than the diameter of the through hole, which can prevent the guide rod 5 from moving too low and detaching from the outer shell 1. A toothed plate 8 is fixedly installed on the side of the guide rod 5 opposite to the gear 4. The tooth surface of the toothed plate 8 is meshed with the gear 4. When the gear 4 rotates with the rotating rod 12, the tooth surface meshing drives the guide rod 5 to move up and down, thereby driving the latch body 2 to slide along the slide groove 3.

[0021] Reference Figures 2-3 The multi-position locking mechanism also includes a position adjustment component and a dust cover 10. The dust cover 10 is a cylindrical hollow structure that is fitted over the position adjustment component. One end of the dust cover 1 is fixedly connected to the front of the outer shell 1 by bolts, and the other end is hinged to a dust cover 9 by a hinged lock body. The dust cover 9 can rotate around the hinge point to open and close. When closed, it can prevent dust from entering the connection between the position adjustment component and the rotating rod 12, thus playing a dust protection role. The dust cover 10 and the dust cover 9 are connected by a key lock cylinder. Only authorized personnel can open the dust cover 9 with a key to prevent unauthorized personnel from switching positions.

[0022] Reference Figure 4 and Figure 5 The gear adjustment component includes a circular plate 14 and multiple gear markings. The circular plate 14 is fixedly sleeved on the outer wall of the internal threaded sleeve rod 13. The multiple gear markings (such as locked, half open, and fully open) are engraved on the side of the circular plate 14 opposite to the second limit plate 18, so that the operator can intuitively observe the current gear status.

[0023] The device also includes a disc 15, which is movably sleeved on the outer wall of the rotating rod 12 between the internal threaded sleeve rod 13 and the second limiting plate 18, and is fixedly connected to the disc 14. The gear slots 16 are evenly opened on the edge of the disc 15, and their number is consistent with the multi-gear number and corresponds one-to-one, which is used to realize gear limiting.

[0024] The device also includes a connecting circular plate 17, which is movably sleeved on the outer wall of the rotating rod 12 between the disc 15 and the second limiting plate 18. It can move axially along the rectangular groove on the rotating rod 12. The gear position plate 20 is welded to the side of the connecting circular plate 17 opposite to the disc 15. Its shape is adapted to the gear position slot 16 and can be inserted into the gear position slot 16 to fix the gear position. The lever 21 is welded to the outer wall of the connecting circular plate 17, which allows the operator to move the connecting circular plate 17 axially along the rotating rod 12. When the lever 21 drives the connecting circular plate 17 to rotate, it can drive the rotating rod 12 to rotate synchronously. In use, the gear position can be adjusted by the lever 21 as needed. When the gear position is locked, the locking tongue body 2 completely covers the rectangular insertion port 11, blocking any access operation. When the gear position is half open, the locking tongue body 2 partially covers the rectangular insertion port 11, allowing only specific interfaces to be connected. When the gear position is fully open, the locking tongue body 2 completely avoids the rectangular insertion port 11, facilitating normal access operation.

[0025] The device also includes two baffles 19, which are symmetrically welded to the side of the disc 15 opposite to the connecting disc 17, and correspond to the gear slots 16 at the left and right extreme positions, respectively, to limit the movement range of the connecting disc 17 and prevent the gear plate 20 from leaving the area where the gear slot 16 is located.

[0026] The implementation principle of a network security protection device with physical port locking and abnormal access blocking in this application embodiment is as follows: During installation, the outer casing 1 is fixed to the corresponding position on the network device with bolts, so that the rectangular port 11 is aligned with the network interface to be protected, ensuring that normal access operation is not affected.

[0027] When it is necessary to adjust the gear, first open the hinge lock body of the dust cover 9, rotate the dust cover 9 around the hinge point to the fully open state, revealing the internal lever 21 and gear adjustment component, providing space for subsequent operations; Release gear lock: Move the lever 21 on the outer wall of the connecting round plate 17 by hand, and drive the connecting round plate 17 to move axially along the rectangular groove on the rotating rod 12 (away from the direction of the disc 15) until the gear position plate 20 is completely disengaged from the gear position slot 16 corresponding to the current gear position. At this time, the gear position is released and the rotating rod 12 is ready to rotate. Drive lever 12 to rotate: Keep lever 21 in the shifting state and continue to rotate lever 21 in the target gear direction. Since the connecting circular plate 17 forms a circumferential limit with lever 12 through the rectangular groove (cannot rotate relative to each other), the rotational force of lever 21 is transmitted to lever 12 through connecting circular plate 17, causing lever 12 to rotate synchronously. If lever 12 rotates in the unlocking direction, gear 4 drives toothed plate 8 to move upward, thereby pulling guide rod 5 to move upward synchronously. If it rotates in the locking direction, toothed plate 8 and guide rod 5 move downward synchronously.

[0028] If the guide rod 5 moves upward, the locking tongue body 2 slides along the slide groove 3 away from the rectangular socket 11, gradually avoiding the rectangular socket 11, and the exposed area of ​​the network interface increases (switching from locked to half open and fully open). If the guide rod 5 moves downward, the locking tongue body 2 slides along the slide groove 3 toward the rectangular socket 11, gradually blocking the rectangular socket 11, and the exposed area of ​​the network interface decreases (switching from fully open to half open and locked). After the locking tongue body 2 moves to the target position (corresponding to the locked, half-open, and fully open positions, which can be visually observed through the multi-position markings on the circular plate 14), the position must be fixed and the dustproof reset must be completed to ensure that the device maintains its current protective state. The specific operation is as follows: Re-fixing the gear position: Stop rotating the lever 21, and move the lever 21 in the opposite direction along the axis of the rotating rod 12, which will drive the connecting circular plate 17 to move towards the disk 15, so that the gear position plate 20 is re-locked into the gear position slot 16 corresponding to the gear position on the edge of the disk 15. Since the gear position slot 16 corresponds one-to-one with the multiple gear position numbers, the position of the locking tongue body 2 is fixed at this time, and the network interface remains in the current open or locked state. Limiting the adjustment range: During the rotation of the connecting plate 17 driven by the lever 21, the two baffles 19 symmetrically arranged on the disc 15 play a role in limiting the stroke. When the connecting plate 17 rotates to the extreme position of locking or fully opening, the edge of the connecting plate 17 will contact the baffle 19 on the corresponding side, preventing it from continuing to rotate. This avoids the gear position plate 20 from disengaging from the distribution area of ​​the gear position slot 16 due to over-adjustment, thus ensuring adjustment safety.
