Description

Technical Field

[0001] This utility model belongs to the technical field of data encryption equipment, and specifically relates to a protective device for data encryption equipment. Background Technology

[0002] Data encryption devices encrypt data. These devices typically connect to other devices via data cables and their main components include a power socket, several data interfaces, a heat sink, and a cooling fan. They primarily consist of the hardware circuitry of an encryption chip module and a wireless communication module, along with a communication strategy module. Data is transmitted encrypted after two-way authentication between the data encryption device and the shore-based platform. Data communication tests have verified the feasibility of encrypted communication. Primarily used for financial payments, e-government, and sensitive data encryption, data encryption ensures that even if hackers breach the database, they cannot obtain plaintext data, and unauthorized employees cannot access the data. It is suitable for systems containing large amounts of sensitive information in industries such as finance, government, e-commerce, and logistics.

[0003] To facilitate connection of the data cable connector of the data encryption device to other devices, the data encryption device is usually exposed. This allows the data cable connector to be directly plugged into other devices during use. To extend its lifespan and ensure stable performance, it should be protected and stored after use. However, exposed data encryption devices, if not used frequently, tend to accumulate dust on their outer surface, in crevices, and around the ventilation vents and cooling fan over time. Furthermore, in humid environments, the device is susceptible to moisture damage, which can affect its performance and make it inconvenient to use.

[0004] When in use, the connection point of the device may be damaged by impact, and dust may even enter the device, affecting its use. Due to the complex and variable working environment, accidental contact or data cable collisions and pulling may occur during operation, which may cause the data cable connector to separate from the device, thereby potentially damaging the data encryption device. It is not easy to protect it, resulting in low security and affecting the service life of the data encryption device. Therefore, a protective device for the data encryption device is proposed.

[0005] Data encryption devices require protective casings during installation to withstand harsh natural environments and prevent external impacts. Traditional data encryption device casings with external protective structures come in various shapes, but some problems remain: Most traditional casings are box-shaped, making them susceptible to bumps and knocks after installation due to environmental factors. This can cause the casing to shake, potentially damaging the internal components and posing a safety hazard, thus limiting the usability of the data encryption device casing.

[0006] Existing protective devices for data encryption equipment are inadequate. Because the internal cooling fans and vents of the data encryption equipment generate vibrations during long-term operation, the protective devices, which are fixedly installed on the equipment, can vibrate due to these vibrations, causing internal components to loosen. Furthermore, during assembly, poor clamping and positioning, coupled with the lack of effective protective and support structures, prevents reliable positioning and clamping of the data encryption equipment. This leads to the equipment easily shifting and slipping off the protective device after assembly. The current protective devices are of poor quality and no longer meet production requirements.

[0007] Existing data encryption devices have the following drawbacks: They contain numerous internal wiring connections, often simply piled together, leading to a chaotic internal wiring system. This causes the internal temperature to rise continuously during use, increasing the risk of electric shock. Furthermore, if a short circuit occurs, staff cannot promptly repair the device, affecting its normal operation. The lack of a secure wiring arrangement also makes the wiring prone to tangling. This tangling forces maintenance personnel to spend considerable time identifying and organizing the wires within the device's protective structure, ensuring neat alignment and preventing accidents, thus increasing their workload.

[0008] Therefore, in order to solve the problems existing in the current technology, it has become an important task to study a protective device for data encryption devices. Utility Model Content

[0009] The purpose of this invention is to provide a protective device for data encryption equipment, which solves the problems of easy displacement and collision of data encryption equipment, poor protection quality, and messy internal wiring in existing protective devices for data encryption equipment.

[0010] The technical solution adopted by this utility model is a protective device for a data encryption device, including a protective box. The protective box is cubic in shape, with an opening on one side. A limiting component is set at the opening of the protective box, and a protective component is set inside the protective box. The data encryption device is inserted into the protective box. A ribbon cable assembly is set on the side opposite to the opening on the top of the protective box.

[0011] The present invention is further characterized in that,

[0012] The limiting assembly includes limiting gates, which are rotatably connected to both sides of the opening. The height of each limiting gate is not lower than the horizontal height of the upper surface of the protective box, and the length of each limiting gate does not exceed half the length of the opening.

[0013] Two limit blocks are set at the edge of each limit gate. Limit grooves are set at corresponding positions on the upper and lower surfaces of the protective box. A locking device is set on the upper surface of the protective box. Limit openings are opened inside the limit blocks, and the limit openings are connected to the locking device.

[0014] The locking device includes a slide rail, the direction of which extends is perpendicular to the length direction of the limiting groove. A slider is slidably engaged on the slide rail, and a toggle plate is vertically mounted on the slider. A spring is connected to the toggle plate, and the other end of the spring is connected to the end of the slide rail.

[0015] The slider has a horizontal cross-section that is a right-angled trapezoid. The right-angled side of the trapezoid is close to the spring, and the inclined surface of the trapezoid faces the limiting port. The slider is engaged with the limiting port.

[0016] Each limit gate has a protective pad on its inner side, which is concave in an arc shape relative to the inside of the protective box.

[0017] The protective components include a dustproof pad, which is placed inside the opening of the protective box. Soft pads a are placed in the middle of the upper and lower surfaces of the inner wall of the protective box. The direction in which each soft pad a extends is parallel to the insertion direction of the data encryption device. Soft pads b are placed on the four edges of the upper and lower surfaces of the protective box, and soft pads c are placed on the four edges in the height direction of the protective box.

[0018] The dustproof mat is U-shaped, the soft mat a is long and narrow, and the soft mats b and c are both long and narrow soft mats with two sides perpendicular to each other at right angles.

[0019] The cable assembly includes a rear cover plate, which is integrally mounted on the side opposite the opening of the protective box. Filter ports are provided at both ends of the rear cover plate along its length, and dustproof mesh is installed inside the filter ports. A cable passage unit is opened in the middle of the rear cover plate along its length, and the cable passage unit is located between the two filter ports.

[0020] The cable management unit includes a power port and several data ports, with dust covers corresponding to the data ports; the data encryption device has a power socket, several data interfaces, a heat dissipation vent, and a cooling fan on its rear side; two dust filters correspond to the heat dissipation vent and the cooling fan, the data ports correspond to the data interfaces, and the power port corresponds to the power socket.

[0021] A horizontal support plate is installed at the bottom of the rear cover, with several parallel cable trays on the support plate, corresponding to the number of data ports. Each cable tray is rotatably connected to a sealing cover on one side along the axial direction, and a short cylinder is installed on the other side of each cable tray. A fixing buckle is installed in the middle of the edge of the sealing cover, and the fixing buckle engages with the short cylinder. When there are many connecting cables, each connecting cable is placed in its respective cable tray, the sealing cover is rotated to fix the connecting cable in the cable tray, and the fixing buckle is rotated so that the short cylinder on the sealing cover passes through the fixing buckle.

[0022] The beneficial effects of this utility model are as follows: The protective device for the data encryption equipment of this utility model, including the protective box and limiting components, provides support for the data encryption equipment. The data encryption equipment is pushed into the protective box, and through the protective box and the limiting door, a pair of limiting blocks are fixedly installed on each of the limiting doors. An arc-shaped protective pad is fixed on one side of each limiting door. A limiting groove is opened at the opening of the protective box. The limiting components, through the force of the limiting door, tightly clamp the data encryption equipment, saving space and offering simplicity and convenience. The protective components, by placing soft pads a, b, and c inside the protective box, provide shock absorption and cushioning, reducing vibration and the impact force between the data encryption equipment and the inside of the protective box. The included cable management components clearly arrange the wiring inside the data encryption equipment, facilitating quick maintenance of the equipment's wiring by staff. By using protective pads, dustproof pads, dustproof nets, and dustproof covers in combination, the data encryption equipment is protected. This prevents damage from drops and prevents dust from entering the machine during prolonged use. The support plate, cable tray, sealing cover, short cylinder, and fixing buckle work together to arrange the wires when there are many, preventing them from tangling. This protective device for data encryption equipment effectively positions and reliably clamps the equipment, ensuring neat wire arrangement and enabling timely maintenance. This ensures the normal operation of the data encryption equipment, reduces workload, improves work efficiency, and meets production requirements. Attached Figure Description

The data encryption device 117 is inserted inside the protective box 1. A cable assembly is installed on the opposite side of the opening on the upper part of the protective box 1. This protective device for a data encryption device, through the protective box 1 and the limiting component, can clamp the data encryption device. The cable assembly classifies and fixes the wires of the data encryption device, improving the orderly distribution of the wires. The protective component protects the outer surface of the data encryption device, increases the clamping force, and prevents the wires from loosening. The limiting component includes limiting doors 11, which are rotatably connected to both sides of the opening. The height of each limiting door 11 is not lower than the horizontal height of the upper surface of the protective box 1, and the length of each limiting door 11 does not exceed half the length of the opening. The size of the limiting doors 11 allows operators to open them even in confined spaces, making the data encryption device more practical. Two limiting blocks 12 are provided on the edge of each limiting gate 11. Limiting grooves 14 are correspondingly provided on the upper and bottom surfaces of the protective box 1. A locking device is provided on the upper surface of the protective box 1. A limiting opening is opened inside the limiting block 12, and the limiting opening is connected to the locking device. The locking device includes a slide rail, the direction of which extends perpendicular to the length direction of the limiting groove 14. A slider 15 is slidably engaged on the slide rail. A vertically mounted actuating plate 17 is provided on the slider 15, and a spring 16 is connected to the actuating plate 17. The other end of the spring 16 is connected to the end of the slide rail.

The horizontal cross-section of the slider 15 is a right-angled trapezoid, with the right-angled side of the trapezoid close to the spring 16, and the inclined surface of the trapezoid facing the limiting opening. The slider 15 is engaged within the limiting opening. By engaging the slider 15 with the limiting port, and utilizing the combined use of the limiting gate 11, limiting block 12, limiting groove 14, limiting port, and locking device, the slider 15 is pushed along the slide rail by the actuating plate 17 in the locking device, compressing the spring 16 and disengaging it from the limiting block 12. This allows the limiting gate 11 to open, the spring 16 to reset, and the data encryption device to be removed. After the data encryption device wiring and maintenance are completed, the data encryption device is inserted into the protection box 1, the limiting gate 11 is closed, and the slider 15 engages with the limiting port on the limiting block 12 to secure the data encryption device, improving the stability of the limiting gate 11 and preventing it from shaking during movement.

Soft pads b111 are positioned on the four edges of the upper and lower surfaces of the protective case 1, and soft pads c112 are positioned on the four edges along the height direction of the protective case 1. The dustproof pad 18 is U-shaped, the soft pad a19 is elongated, and the soft pads b111 and c112 are both elongated soft pads with two sides perpendicular to each other, forming a right angle, and are tightly fitted to the data encryption device 117. The soft pads a19, b111, and c112 serve a shock-absorbing and buffering function, preventing the data encryption device from vibrating and pressing against the protective case, thus avoiding damage to the components on the protective case. The cable assembly includes a rear cover plate, which is integrally mounted on one side opposite the opening of the protective box 1. Filter ports are located at both ends of the rear cover plate along its length, with dust filters 113 installed inside each port.

A short cylinder 23 is provided on the other side of each cable tray 21 along the axial direction. A fixing buckle 24 is provided at the center of the edge of the closed cover 22, and the fixing buckle 24 engages with the short cylinder 23. When there are many connecting wires, each connecting wire is placed in each cable tray 21. Rotating the closed cover 22 fixes the connecting wire within the cable tray 21. Rotating the fixing buckle 24 allows the short cylinder 23 on the closed cover 22 to pass through the fixing buckle 24, limiting the closed cover 22 and preventing the connecting wires from tangling. Based on embodiment 12, this embodiment, through the combined use of the support plate, cable tray, closed cover, short cylinder, and fixing buckle, arranges the wires when there are many connecting wires, preventing them from tangling together and making them neater and easier to manage. The clamping and squeezing structure of the connecting lines restricts the movement of the lines connected to the data encryption device, allowing the wires on the data encryption device to extend out of the protective device and connect to other devices. This effectively classifies and organizes the lines, facilitating equipment inspection and maintenance by staff.

Each cable tray 21 is rotatably connected to a closed cover 22 along one side of the axial direction.

Through the coordinated use of the support plate, cable trays, closed covers, short cylinders, and fixing buckles, the wires are arranged when there are many connecting wires, preventing them from tangling together and making them neater and easier to manage. The clamping and squeezing structure of the connecting wires restricts the movement of the wires connected to the data encryption device, allowing the wires on the data encryption device to extend out of the protective device and connect to other devices. This effectively classifies and organizes the wires, facilitating equipment inspection and maintenance by staff. An insulating coating is provided on the outer surface of the protective box 1, which increases the insulation of the protective box 1.Based on Example 14, in this example, the protective pad, dustproof pad, soft pad a, soft pad b, and soft pad c are all made of flexible materials. They work together to effectively protect the outer wall of the data encryption device, absorb the vibration force generated by the operation of the data encryption device, effectively reduce the vibration force on the protective box 1, and enable the protective box 1 to stably control the operation of the data encryption device; and prevent scratches and collisions to the data encryption device during movement and handling.

[0068] The working principle of the protective box of the data encryption device of this utility model is as follows: a limit block 12 is arranged on one side of the limit gate 11, and a limit port is opened on each limit block 12. The slider 15 is locked in the limit port; the soft pad b111 is located at the four corners of the long side of the protective box 1, the soft pad c112 is located at the two corners of the short side of the protective box 1, the soft pad a19 is located at the center of the upper and lower surfaces inside the protective box 1, and the actuating plate 17 passes through the limit groove 14.

[0069] The actuating plate 17 drives the slider 15 to slide towards the limiting groove 14, thus removing the restriction on the limiting block 12. The limiting door 11 opens, and the data encryption device 117 is inserted into the protective box 1. Rotating the limiting door 11 causes the limiting block 12 to insert into the limiting groove 14. The limiting block 12 presses against the inclined side of the slider 15, causing the slider 15 to move into the limiting groove 14 and compress the spring 16. When the limiting door 11 closes, the slider 15 is inserted into the limiting opening on the limiting block 12 for limiting. When the limiting door 11 is closed, the protective pad 13 is in contact with the data encryption device 117. When a data connection cable needs to be inserted, the dust cover 116 is rotated. When not in use, the dust cover 116 is removed due to its weight. The force will block the data port 114 to prevent dust from entering and causing poor contact. The dustproof net 113 prevents dust from entering the data encryption device 117 when it is cooling down. The protective box 1 protects the data encryption device 117 inside. When it is dropped, the protective pad 13, soft pad b111, soft pad c112 inside the protective box 1 effectively reduce the impact force generated by the drop. Through the combined use of the protective pad 13, dustproof pad 18, soft pad a19, soft pad b111, soft pad c112, dustproof net 113 and dustproof cover 116, the data encryption device 117 is protected and prevented from being damaged when dropped. It can also prevent dust from entering the machine after long-term use.

[0070] A support plate 2 is fixedly installed on the rear side of the protective box 1. Multiple movable cable trays 21 are provided on the support plate 2. Each support plate 2 has a rotatable cover 22, and each cover 22 has a fixed short cylinder 23. Multiple fixing buckles 24 are rotatably installed on the support plate 2, with the short cylinders 23 passing through the fixing buckles 24. Each cable tray 21 corresponds to a cover 22 and a data port 114. Each connecting cable is placed in its respective cable tray 21, solving the problem of cables easily tangling and being difficult to manage. Rotating the cover 22 fixes the connecting cable within the cable tray 21. Rotating the fixing buckle 24 allows the short cylinders 23 on the cover 22 to pass through the fixing buckle 24, limiting the position of the cover 22. Through the coordinated use of the support plate 2, cable trays 21, cover 22, short cylinders 23, and fixing buckles 24, cables can be arranged when there are many cables, preventing them from tangling.

[0071] The working process of the protective device of the data encryption device of this utility model is as follows: the toggle plate 17 is manually moved, the toggle plate 17 drives the slider 15 to slide into the limiting groove 14, loses the restriction on the limiting block 12, opens the limiting door 11, and inserts the data encryption device 117 into the protective box 1.

[0072] Rotating the limiting gate 11 causes the limiting block 12 to insert into the limiting groove 14. The limiting block 12 presses the inclined side of the slider 15, causing the slider 15 to move into the limiting groove 14 and compress the spring 16. When the limiting gate 11 is closed, the slider 15 is inserted into the limiting port on the limiting block 12 for limiting. When the limiting gate 11 is closed, the protective pad 13 is in contact with the data encryption device 117. When the data connection cable is inserted, the dust cover 116 is rotated. When not in use, the dust cover 116 will block the data port 114 due to gravity to prevent dust from entering and causing poor contact. The dust net 113 prevents dust from entering the data encryption device 117 when it is cooling down, thus affecting the service life of the device. The protective box 1 protects the data encryption device 117 inside. When it is dropped, the protective pad 13, soft pad b111, and soft pad c112 inside the protective box 1 effectively reduce the impact force generated by the drop and reduce the possibility of device damage.

[0073] The protective device for this data encryption equipment uses a protective box and limiting components to position and reliably clamp the equipment. A locking device secures and supports the equipment, ensuring its stable operation and preventing displacement or vibration that could affect efficiency. The arrangement of this protective device meets the requirements for normal operation, facilitates maintenance, does not endanger personnel or surrounding equipment, and extends the equipment's lifespan, making it safe and effective.

As will be clearly understood by those skilled in the art, various technical interactions and operations are possible. Furthermore, various embodiments can be implemented individually or in combination.
