[0006] According to the above technical solution, a rack is slidably connected to the outer wall of the interface seat, and a gear is fixed to the outer wall of the rotating rod. The gear meshes with the rack, and the gear is used to make the rotating rod rotate smoothly.

[0007] According to the above technical solution, an anti-theft mechanism is provided above the interface socket to prevent data theft; an alarm mechanism is provided above the interface socket to issue an alarm when information theft occurs.

[0008] According to the above technical solution, the anti-theft mechanism includes: a trapezoidal plate, which is fixed on the side of the baffle near the interface seat; A long slot is formed inside the interface seat; A positioning plate, which is slidably connected to the inner wall of the long slot; A lower spring, one end of which is fixed to the inner wall of the long slot, and the other end of which is fixedly connected to the locking plate; A short post, which is fixed to the side wall of the positioning plate; A movable plate, which is slidably connected to the outer wall of the short column.

[0009] According to the above technical solution, an upper spring is fixed on the side of the positioning plate near the moving plate, and the upper spring is fixedly connected to the moving plate. A limit hole is opened on the side of the rack away from the interface seat.

[0010] According to the above technical solution, a fixing member is fixed to the outer wall of the housing, and a locking rod is passed through the fixing member and slidably connected at the passage. A locking spring is fixed to the side of the fixing member near the gear, and the locking spring is fixedly connected to the locking rod. The limiting hole is used to lock the locking rod.

[0011] According to the above technical solution, the alarm mechanism includes: a cavity, which is formed inside the card plate; An L-shaped plate is slidably connected to the inner wall of the cavity; A reset spring, one end of which is fixed to the lower side wall of the L-shaped plate, and the other end of which is fixedly connected to the inner wall of the cavity; A connecting plate, which is fixed to the upper side wall of the L-shaped plate; A thin spring, one end of which is fixed to the side wall of the connecting plate, and the thin spring is fixedly connected to the housing; A trigger rod is fixed to the side of the connecting plate away from the baffle, and the trigger rod passes through the housing and is slidably connected at the point of penetration; A buzzer, which is fixed above the interface base.

[0012] According to the above technical solution, a small slot is provided on the outer wall of the housing, and a locking rod is slidably connected to the inner wall of the small slot. A short spring is fixed to the end of the locking rod, and the short spring is fixedly connected to the inner wall of the small slot. The locking rod is used to limit the position of the connecting plate.

[0013] This invention provides an industrial network security encryption device based on 5G communication technology. It has the following beneficial effects: 1. This invention, by setting up a housing, interface seat, network cable port, connecting seat, rotating rod, torsion spring, and baffle, allows for the following: Before inserting a network cable into the network cable port, the limiting rod is moved to disengage from the limiting groove. Simultaneously, the rotating rod and baffle rotate upwards by 90° under the reset action of the torsion spring. At this point, the baffle no longer obstructs the network cable port, allowing for the replacement or insertion of the network cable. This protects the network cable port from easy insertion and removal of the network cable, safeguarding the network security of the encryption device. Furthermore, by incorporating the limiting rod, limiting spring, limiting groove, gear, and rack, the rotating rod drives the gear to rotate during the rotation of the rotating rod and baffle, which in turn drives the rack to move. This slows down and stabilizes the rotation speed of the rotating rod and baffle, preventing the network cable already inserted into the port from being scratched by the notch in the baffle during its upward rotation, thus protecting the network cable.

[0014] 2. This invention, through the arrangement of a trapezoidal plate, a long slot, a lower spring, a locking plate, a short column, an upper spring, and a movable plate, allows the trapezoidal plate to press against the movable plate during the baffle's rotation. When the trapezoidal plate touches the movable plate, the movable plate moves towards the locking plate. If a network cable is inserted into the network cable port at this time, the locking plate remains stationary, while the movable plate moves towards the locking plate, and the upper spring is compressed. If the network cable is pulled out at this time, the locking plate immediately moves into the network cable port under the elastic force of the upper spring, and the lower spring is stretched. To insert another network cable into the port, the baffle must be manually rotated downwards until the trapezoidal plate is just no longer pressing against the movable plate. At this point, the locking plate also resets under the reset action of the lower spring. Then, a network cable can be inserted into the network cable port, making it difficult for non-staff members to know how to plug and unplug the network cable, thus providing network security protection at the network cable port. At the same time, by setting limit holes, fixing parts, locking rods and locking springs, when inserting a network cable into the network cable port, the baffle needs to be manually flipped until the trapezoidal plate is just disengaged from the moving plate. During this process, the flipping angle is difficult to control. During the manual flipping of the baffle and the rotating rod, the rack moves downward. Since the locking rod is always in contact with the rack under the action of the locking spring, when the locking rod coincides with the limit hole on the rack, the locking rod is locked into the limit hole under the elastic force of the locking spring, so that the baffle remains stationary at this time, and the trapezoidal plate is just disengaged from the moving plate, making it convenient for staff to insert the network cable.

[0015] 3. This invention, by incorporating a cavity, an L-shaped plate, a return spring, a connecting plate, a thin spring, a trigger rod, and a buzzer, allows the following mechanism: When a non-staff member releases the barrier, the locking plate moves the L-shaped plate into the network cable port. If the network cable is directly inserted into the port, the cable's connector presses against the L-shaped plate, pushing it inwards. Simultaneously, the return spring compresses, causing the upper part of the L-shaped plate to move the connecting plate and the trigger rod closer to the buzzer. Again, the thin spring compresses, and when the trigger rod touches the buzzer's switch, the buzzer sounds an alarm, alerting the staff. Upon receiving the alarm, staff came to investigate, protecting the network security of the encryption device. Simultaneously, by incorporating a small slot, a short spring, and a locking lever, when the connecting rod presses against the inclined end of the locking lever, it forces the locking lever to move into the small slot. Accompanied by the compression of the short spring, once the connecting rod exceeds the position of the locking lever, the elastic force of the thin spring keeps the connecting rod pressed tightly against the locking lever, thus maintaining the state where the trigger lever is constantly pressed against the buzzer switch. This causes the buzzer to continuously sound an alarm, serving as a strong warning and deterring unauthorized personnel from continuing to tamper with the encryption device.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Please see Figures 1-9 One embodiment of the present invention is: an industrial network security encryption device based on 5G communication technology, comprising: a housing 1, a network cable port 3, a connecting seat 4, a rotating rod 5, a baffle 7, a torsion spring 6, a square plate 15, a limiting groove 10, a limiting rod 8, a limiting spring 9, a rack 12, and a gear 11; the side wall of the housing 1 has an interface seat 2 passing through it and is fixedly connected at the point of penetration; the network cable port 3 is opened on the outer side wall of the interface seat 2; the connecting seat 4 is fixed to the upper wall of the interface seat 2; the rotating rod 5 passes through the connecting seat 4 and is rotatably connected at the point of penetration; the baffle 7 is fixed to the outer wall of the rotating rod 5; One end of the torsion spring 6 is fixed to the side wall of the connecting seat 4, and the other end of the torsion spring 6 is fixedly connected to the baffle 7; the square plate 15 is fixed to the side wall of the connecting seat 4; the limiting groove 10 is opened on the outer wall of the rotating rod 5, and the limiting rod 8 passes through the square plate 15 and is slidably connected at the point of penetration; one end of the limiting spring 9 is fixed to the side wall of the square plate 15 away from the rotating rod 5, and the limiting spring 9 is fixedly connected to the limiting rod 8; the rack 12 is slidably connected to the outer wall of the interface seat 2; the gear 11 is fixed to the outer wall of the rotating rod 5, and the gear 11 meshes with the rack 12. The gear 11 is used to make the rotating rod 5 rotate smoothly.

[0020] By specially designing the housing 1, interface socket 2, network cable port 3, connector 4, rotating rod 5, torsion spring 6, and baffle 7, the network cable is effectively prevented from being easily plugged in and unplugged, protecting the network security of the encryption device and avoiding security risks such as network interruption and data leakage caused by illegal plugging and unplugging of the network cable. By using the limiting rod 8, limiting spring 9, limiting groove 10, gear 11 and rack 12, the wire harness that is already inserted into the network cable port 3 can be effectively prevented from being scratched or worn by the notch of the baffle 7 during the upward flip of the baffle 7. This provides good protection for the wire harness, extends the service life of the network cable, and avoids network connection problems caused by wire harness damage.

[0021] In this embodiment, before inserting or replacing the network cable into the network cable port 3, the operator needs to manually move the limiting rod 8 to disengage it from the limiting groove 10, thus releasing the limiting constraints on the rotating rod 5 and the baffle 7. At the same time, the torsion spring 6, which was originally in a pre-tightened state, will immediately release its elastic potential energy. Under the action of the reset elastic force, it will drive the rotating rod 5 and the baffle 7 to rotate upward by 90° until the baffle 7 is perpendicular to the surface of the interface seat 2. At this time, the baffle 7 no longer blocks the network cable port 3, and the operator can smoothly insert or replace the network cable.

[0022] During the upward rotation of the rotating rod 5 and the baffle 7 under the action of the torsion spring 6, the rotating rod 5 will drive the gear 11 to rotate synchronously. Since the gear 11 and the rack 12 mesh with each other, the rotational motion of the gear 11 will be converted into the linear motion of the rack 12. The rack 12 will be subject to a certain resistance during the sliding process, which will buffer the rotation of the gear 11, making the rotation speed of the rotating rod 5 and the baffle 7 slower and smoother, avoiding the impact force caused by excessive rotation speed.

[0023] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, an anti-theft mechanism is provided above the interface base 2 to prevent data theft; an alarm mechanism is provided above the interface base 2 to issue an alarm when information theft occurs.

[0024] The anti-theft mechanism includes: a trapezoidal plate 1301, a long slot 1302, a locking plate 1304, a lower spring 1303, a short column 1305, a movable plate 1307, an upper spring 1306, a limiting hole 1308, a fixing component 1309, a locking rod 1310, and a locking spring 1311; the trapezoidal plate 1301 is fixed to the side of the baffle 7 near the interface seat 2; the long slot 1302 is opened inside the interface seat 2; the locking plate 1304 is slidably connected to the inner wall of the long slot 1302; one end of the lower spring 1303 is fixed to the inner wall of the long slot 1302, and the other end of the lower spring 1303 is fixedly connected to the locking plate 1304; the short column 1305 is fixed to the side wall of the locking plate 1304; and the movable plate 1307 is slidably connected to the outer wall of the short column 1305. The upper spring 1306 is fixed to the side of the locking plate 1304 near the moving plate 1307, and the upper spring 1306 is fixedly connected to the moving plate 1307. The limiting hole 1308 is opened on the side of the rack 12 away from the interface seat 2. The fixing member 1309 is fixed to the outer wall of the housing 1. The locking rod 1310 passes through the fixing member 1309 and is slidably connected at the passage. The locking spring 1311 is fixed to the side of the fixing member 1309 near the gear 11, and the locking spring 1311 is fixedly connected to the locking rod 1310. The limiting hole 1308 is used to lock the locking rod 1310.

[0025] By setting up a trapezoidal plate 1301, a long slot 1302, a lower spring 1303, a locking plate 1304, a short post 1305, an upper spring 1306, and a movable plate 1307, the network security protection of the network cable port 3 is further strengthened, preventing unauthorized personnel from plugging and unplugging the network cable at will, and improving the network security of the encryption device.

[0026] The setting of limiting hole 1308, fixing part 1309, locking rod 1310 and locking spring 1311 makes it convenient for staff to accurately control the flip angle of baffle 7, avoid the inability to insert network cable due to improper flip angle, and effectively solve the problem of difficult angle control when manually flipping baffle 7.

[0027] In this embodiment, the alarm mechanism includes: a cavity 1401, an L-shaped plate 1402, a reset spring 1403, a connecting plate 1404, a thin spring 1405, a trigger rod 1406, a buzzer 1410, a small slot 1407, a locking rod 1409, and a short spring 1408; the cavity 1401 is formed inside the locking plate 1304; the L-shaped plate 1402 is slidably connected to the inner wall of the cavity 1401; one end of the reset spring 1403 is fixed to the lower side wall of the L-shaped plate 1402, and the other end of the reset spring 1403 is fixedly connected to the inner wall of the cavity 1401; the connecting plate 1404 is fixed to the upper side wall of the L-shaped plate 1402; one end of the thin spring 1405 is fixed to the side wall of the connecting plate 1404, and the thin spring 1405 is fixedly connected to the housing 1. The trigger rod 1406 is fixed on the side of the connecting plate 1404 away from the baffle 7. The trigger rod 1406 passes through the housing 1 and is slidably connected at the point of penetration. The buzzer 1410 is fixed above the interface seat 2. The small slot 1407 is opened on the outer wall of the housing 1. The locking rod 1409 is slidably connected to the inner wall of the small slot 1407. The short spring 1408 is fixed to the end of the locking rod 1409. The short spring 1408 is fixedly connected to the inner wall of the small slot 1407. The locking rod 1409 is used to limit the connection plate 1404.

[0028] By incorporating a cavity 1401, an L-shaped plate 1402, a reset spring 1403, a connecting plate 1404, a thin spring 1405, a trigger rod 1406, and a buzzer 1410, real-time early warning of unauthorized insertion and removal is achieved, further protecting the network security of the encryption device.

[0029] The small slot 1407, short spring 1408, and locking lever 1409 provide a strong deterrent to non-staff members, preventing them from continuing to illegally operate the encryption device. This further strengthens the network security protection of the encryption device and comprehensively ensures its normal operation and data security.

[0030] In this embodiment, during the flipping process of the baffle 7, the baffle 7 will drive the bottom trapezoidal plate 1301 to flip synchronously. When the trapezoidal plate 1301 flips to contact the moving plate 1307, the inclined surface of the trapezoidal plate 1301 will exert a squeezing force on the moving plate 1307, pushing the moving plate 1307 towards the direction of the locking plate 1304. If a network cable is inserted into the network cable port 3 at this time, the network cable will block the locking plate 1304, keeping the locking plate 1304 stationary. At this time, the moving plate 1307 continues to move towards the locking plate 1304 under the squeezing of the trapezoidal plate 1301, and the upper spring 1306 will be squeezed and undergo elastic compression deformation, storing elastic potential energy. If the staff unplugs the network cable at this time, the obstruction effect on the locking plate 1304 disappears. Under the elastic reset action of the upper spring 1306, the locking plate 1304 will immediately move into the network cable port 3. At the same time, the lower spring 1303 will be stretched, undergoing elastic deformation and storing potential energy. If the staff wants to continue inserting the network cable into the network cable port 3, the staff needs to manually flip the baffle 7 downwards until the trapezoidal plate 1301 is just out of pressure on the moving plate 1307. At this time, the pressure force on the moving plate 1307 disappears, and under the elastic reset action of the lower spring 1303, the locking plate 1304 will simultaneously reset and exit the network cable port 3. Then, the network cable can be smoothly inserted into the network cable port 3. This design makes it impossible for non-staff members to understand the operation procedure and know how to insert and unplug the network cable, thus providing effective network security protection at the network cable port 3 and preventing unauthorized insertion and unplugging.

[0031] When inserting a network cable into network cable port 3, the operator needs to manually flip the baffle 7 downwards until the trapezoidal plate 1301 is just disengaged from the position of the moving plate 1307. During this process, the baffle 7 drives the rotating rod 5 and the gear 11 to rotate, and the gear 11 drives the rack 12 to move downwards. Because the locking rod 1310 is always in close contact with the surface of the rack 12 under the action of the locking spring 1311, when the rack 12 moves to the position where the locking rod 1310 coincides with the position of the limiting hole 1308 on the rack 12, the locking rod 1310 quickly pops out under the elastic force of the locking spring 1311 and accurately locks into the limiting hole 1308, which plays a limiting and fixing role for the rack 12, thereby keeping the rotating rod 5 and the baffle 7 stationary. At this time, the trapezoidal plate 1301 is just disengaged from the moving plate 1307, and the locking plate 1304 returns to its initial position under the action of the return spring 1403, allowing the operator to easily insert the network cable into network cable port 3.

[0032] When an unauthorized person removes the limit switch 7 and attempts to illegally plug or unplug the network cable, the locking plate 1304, under the action of the relevant spring, moves the L-shaped plate 1402 into the network cable port 3, blocking it. If an unauthorized person forcibly inserts the network cable directly into the network cable port 3, the cable's connector will press against the end of the L-shaped plate 1402, generating a pushing force on the L-shaped plate 1402 towards the inside of the cavity 1401, forcing the L-shaped plate 1402 to push inward. During this process, the return spring 1403 will be compressed and undergo elastic compression deformation, storing elastic potential energy. As the L-shaped plate 1402 moves inward, its upper end will drive the connecting plate 1404 to move synchronously towards the buzzer 1410. The connecting plate 1404 will then drive the trigger rod 1406 to move towards the switch direction of the buzzer 1410, while the thin spring 1405 will be compressed and undergo elastic compression deformation. When the trigger lever 1406 moves to contact the switch of the buzzer 1410 and squeezes the switch, the buzzer 1410 will immediately start and emit a loud alarm, so that the staff can receive the alarm information and come to check in time to stop the illegal operation.

[0033] When the connecting plate 1404 moves closer to the buzzer 1410, it presses against the inclined end of the locking lever 1409. Guided by the inclined surface, the connecting plate 1404 forces the locking lever 1409 to move into the small slot 1407. During this process, the short spring 1408 is compressed and undergoes elastic deformation, storing elastic potential energy. When the connecting plate 1404 continues to move beyond the position of the locking lever 1409, the compressive force on the connecting plate 1404 disappears. Under the elastic reset action of the thin spring 1405, the connecting plate 1404 remains pressed against the side of the locking lever 1409, thus keeping the trigger lever 1406 pressed against the buzzer 1410 switch, causing the buzzer 1410 to continuously sound the alarm without stopping.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
