Description

Technical Field

[0001] This utility model relates to the field of data transmission technology, and in particular to a data security transmission device based on encryption technology. Background Technology

[0002] In the digital age, data has become a vital asset for businesses and individuals. With the rapid development of information technology, the frequency and scale of data transmission between different systems and networks are constantly increasing. However, data faces numerous security threats during transmission, such as theft, tampering, and leakage. These security issues not only lead to the leakage of personal privacy and economic losses for businesses, but may also trigger a crisis of social trust. Traditional data transmission methods, such as simple file transfer protocols and ordinary network connections, are insufficient to meet the growing security demands. These methods lack effective encryption measures during transmission, making them vulnerable to exploitation by malicious attackers, resulting in data theft or tampering.

[0003] In existing technologies, traditional data security transmission devices typically use USB flash drives for data transfer. A USB flash drive is an independent storage device that is physically separate from other devices. This means that data is stored on the USB flash drive and is only transferred when the user actively inserts it into the computer. Furthermore, many modern USB flash drives come with encryption features, allowing users to set complex passwords to encrypt the data stored on the USB flash drive. During data transfer, only the recipient with the correct password can decrypt and view the data, further enhancing security.

[0004] However, in the existing technology, because USB flash drives are small and easy to carry, they are easily subject to accidental collisions and damage from the outside world, which reduces their lifespan. Therefore, a data security transmission device based on encryption technology is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a data security transmission device based on encryption technology, which aims to improve the problem that USB flash drives are easily damaged by external factors, resulting in a reduced lifespan.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A data security transmission device based on encryption technology includes a protective shell. A rotating shaft is fixedly connected inside the protective shell, and a USB flash drive is rotatably connected to the outside of the rotating shaft. A U-shaped plate is slidably connected inside the protective shell, and a button is fixedly connected to the top of the U-shaped plate. Two rotating bars are rotatably connected inside the U-shaped plate. Two conduits are fixedly connected inside the protective shell, and a spring is sleeved on the outside of the conduits. A locking block is slidably connected inside the protective shell, and a sliding assembly for portable installation of a string is provided inside the protective shell.

[0008] As a further description of the above technical solution:

[0009] The U-shaped plate is slidably connected to the outside of the two conduits, and the bottom of the two rotating bars is rotatably connected to the top of the card block.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the bottom of the U-shaped plate, and the other end of the spring is fixedly connected to the inside of the protective shell.

[0012] As a further description of the above technical solution:

[0013] The button is externally slidably connected to the inside of the protective shell, and the outside of the latch engages with the inside of the USB flash drive.

[0014] As a further description of the above technical solution:

[0015] The sliding assembly includes a sliding rod, which is slidably connected to the outside of the protective shell. A sliding button is fixedly connected to the top of the sliding rod, and a spring is provided inside the protective shell.

[0016] As a further description of the above technical solution:

[0017] The protective shell has a rope hole inside, and the outside of the sliding rod engages with the inside of the rope hole.

[0018] As a further description of the above technical solution:

[0019] One end of the second spring is fixedly connected to the outside of the sliding rod, and the other end of the second spring is fixedly connected to the inside of the protective shell.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the reaction force of the spring drives the U-shaped plate to slide upward, thereby driving the two rotating bars to rotate in opposite directions and causing the locking block to slide downward and lock into the inside of the USB flash drive, thus fixing the USB flash drive inside the protective shell. This prevents the USB flash drive from becoming loose or falling off due to vibration or shaking, and also prevents accidental collisions and damage to the USB flash drive from the outside, thus extending the service life of the device.

[0022] 2. In this utility model, pressing the sliding button causes the sliding rod to slide, disengaging it from the inside of the rope hole and squeezing the second spring on the rear side. At this time, the string is placed inside the rope hole, and the reaction force of the second spring causes the sliding rod to slide back to its original position, passing through the string and engaging inside the rope hole, thus completing the installation of the string. This reduces the steps of stringing the string, eliminates the need for complicated operations during installation, improves the ease of installation, and saves installation time and effort.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 3This utility model provides an embodiment of a data security transmission device based on encryption technology, comprising a protective shell 1. The protective shell 1 is generally rectangular in shape and its outer shell is made of high-strength stainless steel, possessing good pressure resistance and wear resistance, providing robust protection for the device. A rotating shaft 2 is fixedly connected inside the protective shell 1. The rotating shaft 2 is a cylindrical metal component with a finely polished surface to ensure smooth rotation and provide a rotation midpoint. A USB flash drive 3 is rotatably connected to the outside of the rotating shaft 2. The USB flash drive 3 is generally flat and its outer shell is made of robust stainless steel, possessing not only good impact resistance but also effectively preventing electromagnetic interference. A standard USB interface is provided on its front for data transmission with external devices such as computers. Simultaneously, the USB flash drive 3 contains an advanced encryption chip that can encrypt the stored data, ensuring data security during transmission. The protective shell 1 has a U-shaped plate 4 that slides inside. The U-shaped plate 4 is rectangular and has an internal space to provide sliding space for the subsequent locking structure. A button 5 is fixedly connected to the top of the U-shaped plate 4. The button 5 is a circular stainless steel button with an anti-slip texture for easy operation. When the button 5 is pressed, the U-shaped plate 4 can slide down along the groove inside the protective shell 1. The U-shaped plate 4 has two rotating bars 9 that rotate inside. The rotating bars 9 are used to change the direction of force and drive the subsequent structure to adjust the locking state. The protective shell 1 has two cylindrical guide tubes 6 that are fixedly connected inside. The guide tubes 6 are used to guide and support the subsequent elastic structure and prevent it from deviating. The guide tubes 6 are fitted with springs 7 that provide reaction force to drive the locking structure to slide and lock. The protective shell 1 also has a square block 8 that slides inside. The block matches the slot on the USB flash drive 3 to fix the USB flash drive 3. The protective shell 1 also has a sliding component for attaching a lanyard for easy portability.

[0031] Reference Figures 2 to 3 The U-shaped plate 4 is externally slidably connected to the outside of the two conduits 6. The inside of the U-shaped plate 4 has a round hole to accommodate the conduits 6. The bottom of the two rotating bars 9 is rotatably connected to the top of the locking block 8. By rotating the rotating bars 9, the direction of force is changed, thereby driving the locking block 8 to slide upward, preparing for locking and fixing. One end of the spring 7 is fixedly connected to the bottom of the U-shaped plate 4, and the other end of the spring 7 is fixedly connected to the inside of the protective shell 1. The spring 7 is used to provide a reaction force to drive the U-shaped plate 4 to slide upward and reset, thereby driving the rotating bars 9 to push the locking block 8 to lock inside the USB flash drive 3. The button 5 is externally slidably connected to the inside of the protective shell 1. The outside of the locking block 8 locks with the inside of the USB flash drive 3, thereby fixing the position of the USB flash drive 3 and preventing the USB flash drive 3 from rotating out of the protective shell 1, causing accidental damage and reducing its service life.

[0032] Reference Figure 4The sliding assembly includes a sliding rod 11, which is externally slidably connected to the inside of the protective shell 1. The sliding rod 11 is generally slender and cylindrical, with a smooth surface and good wear resistance, which allows it to slide smoothly inside the protective shell 1. The diameter of the sliding rod 11 is matched with a pre-reserved groove inside the protective shell 1 to ensure that it does not wobble from side to side during sliding. A square-shaped button 12 is fixedly connected to the top of the sliding rod 11. The sliding rod 11 slides by sliding the button 12. A second spring 13 is provided inside the protective shell 1. A rope hole 10 is provided inside the protective shell 1 for threading rope. The sliding rod 11 is inserted to fix the rope. The outside of the sliding rod 11 engages with the inside of the rope hole 10, providing a closed limit for the rope and thus fixing the rope. One end of the second spring 13 is fixedly connected to the outside of the sliding rod 11, and the other end of the second spring 13 is fixedly connected to the inside of the protective shell 1, providing a reaction force for the sliding rod 11 to slide and drive the sliding rod 11 to re-engage inside the rope hole 10.

[0033] Working principle: First, the operator rotates the USB flash drive 3 outside the rotating shaft 2 and inserts it into the computer's interface. By entering the encryption password set inside the USB flash drive 3, the data inside the USB flash drive 3 is transferred to the computer. After use, pressing button 5 causes the U-shaped plate 4 to slide downwards outside the guide tube 6, squeezing the spring 7 at the bottom. At the same time, as the U-shaped plate 4 slides downwards, it causes the two rotating bars 9 to rotate, thereby causing the locking block 8 to slide upwards. Then, rotating the USB flash drive 3 again causes the slot on the USB flash drive 3 to match the locking block 8. Then, releasing button 5 causes the U-shaped plate 4 to slide upwards through the reaction force of spring 7, thereby causing the two rotating bars 9 to rotate in the opposite direction, causing the locking block 8 to slide downwards and lock into the inside of the USB flash drive 3, fixing the USB flash drive 3 inside the protective shell 1. This fixing method not only enhances the stability of the device and prevents the USB flash drive 3 from loosening or falling off due to vibration or shaking, but also prevents accidental collisions and damage to the USB flash drive 3 from the outside, extending the service life of the device.

[0034] Secondly, when installing the string on the protective shell 1, pressing the sliding button 12 causes it to slide, which in turn causes the sliding rod 11 to slide and disengage from the inside of the string hole 10, squeezing the second spring 13 on the rear side. At this time, the string is placed inside the string hole 10, and the sliding button 12 is released. The reaction force of the second spring 13 causes the sliding rod 11 to slide back to its original position, pass through the string, and engage inside the string hole 10, completing the installation of the string. This reduces the steps of stringing the string, eliminates the need for complicated operations during installation, improves the portability of the installation, and saves installation time and effort.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
