Description

Technical Field

[0001] This invention relates to the field of account encryption and decryption technology, specifically to a business virtual account management encryption and decryption device and its usage method. Background Technology

[0002] Existing technologies often contain a large amount of trade secrets in business virtual accounts, thus requiring special passwords for encryption. However, traditional combination keyboard symbol encryption is easily cracked. Therefore, existing technologies typically design long, multi-digit asymmetric combination passwords. These passwords are difficult for people to remember, so they are usually stored on a USB flash drive. When logging in, the USB flash drive is plugged in to connect to the system, and the password can be directly imported to achieve the purpose of encryption and decryption.

[0003] However, in actual use, existing USB flash drives can only store one set of passwords. When multiple sets of passwords are stored on the same USB flash drive, during the connection process, the system will scan all the data on the USB flash drive and then select the corresponding connection. However, during the scanning process, if the system is infected with a Trojan or hacked, the traces generated by the scanning process are very easy to be discovered and thus cracked, resulting in the leakage of all the data on the USB flash drive.

[0004] Current USB flash drive designs lack the function of physically selecting passwords. In order to protect the USB flash drive interface, USB flash drives are usually designed to be retractable. This causes the internal cables to be repeatedly stretched and retracted, which can easily affect the stability of data transmission. Adding a cable guide and limit device would increase the length of the USB flash drive's casing. Summary of the Invention

[0034] 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.

[0035] Please see Figures 1 to 9 The present invention provides a technical solution:

[0036] Example 1: A business virtual account management encryption and decryption device, the encryption and decryption device includes a front shell 1 and a rear shell 2.

[0037] A data interface 4 is slidably mounted on the front end of the front housing 1. A push plate 14 for driving the data interface 4 to slide is slidably mounted on the outer wall of the middle section of the front housing 1. A connecting connector 8 is provided at the rear end of the front housing 1. The connecting connector 8 and the data interface 4 are electrically connected through a data cable 15. A chip module 3 is provided in the rear housing 2. A plurality of connecting seats 9 corresponding to the connecting connector 8 are arranged in a circular array at the front end of the chip module 3. A plurality of program links and data for storing encryption and decryption are provided in the chip module 3. The plurality of connecting seats 9 arranged in a circular array are individually electrically connected to each program link and data.

[0038] By setting up multiple sets of connectors 9, the multiple sets of passwords stored in the chip module 3 are separated into their own connectors 9, thus achieving physical separation of the passwords and enabling them to be independent of each other in the password decoding process.

[0039] The outer edge of the rear housing 2 is provided with a folding tube 13 adapted to telescopic movement. The other end of the folding tube 13 is rotatably mounted on the front housing 1. A T-shaped plate 10 is elastically mounted on the front housing 1. A rotating rod that is rotatably connected to the chip module 3 is provided on one side of the T-shaped plate 10.

[0040] The relative rotation installation of the rear outer shell 2 is achieved by using the folded tube 13 and the T-shaped plate 10. Before use, select the corresponding connecting seat 9 and rotate the rear outer shell 2 to make the connecting seat 9 correspond to the connecting joint 8.

[0041] A card holder 21 is provided in the inner cavity of the front housing 1. A pair of rollers are provided on the card holder 21 to slide up and down to hold the data cable 15. A quarter-circular arc groove 22 is provided on the inner wall of the front housing 1. A roller 39 is provided at the end of the card holder 21. The roller 39 is slidably installed in the arc groove 22. The card holder 21 is smoothly connected to the push plate 14 through the pull rope 16. A traction rope 12 is provided on the other side of the T-shaped plate 10. The traction rope 12 extends along the lower end of the arc groove 22 and is fixedly connected to the card holder 21.

[0042] In the prior art, in order to guide and limit the folding of the data cable 15, a guide component needs to be installed in the middle of the data cable 15. This causes the guide component to interfere with the storage of the data interface 4, affecting the storage space. In this application, during the storage process, if... Figure 1 As shown, under the action of the traction rope 12 and the pull rope 16, the card holder 21 rotates downward along the arc groove 22 and forms an upper and lower misalignment with the data interface 4.

[0043] When in use, pushing the push plate 14 causes the pull rope 16 to rotate the card holder 21 along the arc groove 22, thereby causing the data cable 15 to unfold and straighten, adapting to the extension of the data interface 4. Simultaneously, the traction rope 12 drives the T-shaped plate 10 to slide laterally, causing the rear shell 2 to slide towards the front shell 1. The folding tube 13 is folded to adapt to the sliding of the rear shell 2, so that the connecting connector 8 and the connecting seat 9 are electrically connected, achieving the conduction of the data circuit. Thus, the electrical connection inside the USB flash drive can be achieved simply by pushing the push plate 14.

[0044] Example 2: Based on Example 1, in order to ensure the positional limitation of the extended data interface 4, a pair of side strips 5 are provided on the inner outer wall of the data interface 4. The side strips 5 are located in the inner cavity of the front outer shell 1. Please refer to... Figure 3 A telescopic rod 24 is provided on the inner wall of the front outer shell 1, located directly above the side strip 5. An elastic pressure plate 6 is provided at the lower end of the telescopic rod 24. A second spring 23 is sleeved on the telescopic rod 24. The lower end of the second spring 23 is pressed against the elastic pressure plate 6. The lower end of the elastic pressure plate 6 slides against the end face of the side strip 5.

[0045] By designing the side strip 5 to limit the extension length of the data interface 4, and utilizing the cooperation of the second spring 23 and the telescopic rod 24, the elastic pressure plate 6 has a downward squeezing force, ensuring that the side strip 5 slides under a large positive pressure, thereby achieving the telescopic stability of the data interface 4 and avoiding instability in the position of the data interface 4 due to free telescopic sliding.

[0046] Example 3: Based on Example 2, in order to achieve the elastic installation of the T-shaped plate 10 and ensure the smooth movement of the card holder 21 on the arc groove 22, a telescopic groove 7 is provided in the inner cavity of the front outer shell 1 near the rear outer shell 2. The end plate of the T-shaped plate 10 is slidably installed in the telescopic groove 7. A first spring 11 is provided in the telescopic groove 7. The first spring 11 is pressed between the inner wall of the telescopic groove 7 and the T-shaped plate 10. The rotating rod on one side of the T-shaped plate 10 extends to the outer side of the front outer shell 1 and is rotatably connected to the end face of the chip module 3 through a bearing. The traction rope 12 on the other side of the T-shaped plate 10 slides into the front inner cavity of the front outer shell 1. The position of the traction rope 12 is parallel and offset from the position of the data interface 4. A guide wheel 17 is provided in the front inner cavity of the front outer shell 1. The guide wheels 17 are vertically spaced along the upper end port of the arc groove 22.

[0047] The T-shaped plate 10 is elastically installed by setting the telescopic groove 7 and the first spring 11. Then, when it is retracted, the return force of the first spring 11 pulls the traction rope 12, so that the card seat 21 is reset along the arc groove 22. By setting the traction rope 12 to extend along the height of the lower end of the arc groove 22, the traction rope 12 is pulled during the rising of the card seat 21. By setting the guide wheel 17, the traction force of the pull rope 16 acts along the extension direction of the arc groove 22, ensuring that the card seat 21 slides smoothly along the arc groove 22 under the action of the pull rope 16.

[0048] Example 3: Please refer to Figure 1 and Figure 4Based on Embodiment 2, in order to achieve the rotation and extension adaptation of the rear outer shell 2 on the front outer shell 1, one end of the folding tube 13 is fixed to the rear outer shell 2, and the other end of the folding tube 13 is provided with a circular rotating plate 28. A fixed circular ring plate 26 is fixedly provided on the outer wall of the rear end port of the front outer shell 1. The fixed circular ring plate 26 and the circular rotating plate 28 are rotatably fitted together, and the outer sides of the fixed circular ring plate 26 and the circular rotating plate 28 are limited and connected by a pair of half-ring clamps 27. The circular rotating plate 28 is rotatably mounted on a pair of half-ring clamps 27. In the ring clamp 27, the end face of the fixed ring plate 26 near the ring rotating plate 28 is set as a step shape. The outer stepped surface of the fixed ring plate 26 is provided with screw holes distributed in a circumferential array. The inner stepped surface of the fixed ring plate 26 is rotated and fitted with the ring rotating plate 28. One side of the half ring clamp 27 is inserted into the outer stepped surface of the fixed ring plate 26, and the other side of the half ring clamp 27 is pressed against the outer end face of the ring rotating plate 28. A bolt is inserted through the half ring clamp 27, and the threaded end of the bolt is rotated and installed in the screw hole.

[0049] By setting a semi-ring clamp 27, the circular rotating plate 28 is rotated on the fixed circular ring plate 26, thereby adapting to the rotation of the rear outer shell 2 while maintaining the connection. The folding tube 13 is used to adapt to the extension and retraction of the rear outer shell 2 to the front outer shell 1 under the rotating connection.

[0050] Multiple sets of heat dissipation grooves 25 are arranged in a circumferential array on the outer arc wall of the end of the chip module 3. The inner diameter of the folded tube 13 is larger than the inner diameter of the chip module 3. One end of the heat dissipation groove 25 is connected to the annular gap between the chip module 3 and the inner wall of the folded tube 13. The other end of the heat dissipation groove 25 is connected to the gap between the end of the chip module 3 and the rear end of the front shell 1. The folded tube 13 is provided with linearly spaced through holes.

[0051] The gap between the rear outer shell 2 and the front outer shell 1 is compressed, allowing airflow to be discharged along the heat dissipation groove 25 and the through hole, thereby utilizing the heat dissipation groove 25 for heat dissipation. When stored, the rear outer shell 2 is moved away from the front outer shell 1, causing the folded tube 13 to be stretched and the through hole to be stretched into a narrow slit, achieving the purpose of sealing and protection. When in use, the folded tube 13 is compressed, causing the through hole to open and maintain communication with the heat dissipation groove 25, thereby achieving effective heat dissipation.

[0052] Example 4: Based on Example 3, in order to further improve the pushing stability and position fixation of the push plate 14 and prevent it from automatically resetting under the action of the spring, this application also has a transverse sliding groove 18 provided on the outer wall of the middle section of the front housing 1, a through groove 19 provided on the transverse sliding groove 18 to communicate with the inner cavity of the front housing 1, a connecting rod 20 extending along the through groove 19 and connected to the data interface 4 provided at the lower end of the push plate 14, and the transverse sliding groove 18 is vertically positioned near the front end of the front housing 1. A slot 40 is provided, and a push plate 14 is slidably installed in the slot 40. The inner cavities on both sides of the push plate 14 that are in contact with the inner wall of the transverse slide groove 18 are provided with sliding grooves 35. The inner cavity of the push plate 14 is vertically provided with lifting grooves 29 that are perpendicular to the sliding grooves 35. A pair of elastically installed pressure blocks 33 are provided in the sliding grooves 35. A tapered rod 38 is vertically elastically installed in the lifting grooves 29. A tapered hole semi-ring 32 is sleeved on the outer wall of the middle section of the tapered rod 38. The tapered hole semi-ring 32 and the pressure block 33 are connected by a crossbar 34.

[0053] A pressure tube 30 is provided at the upper end of the tapered rod 38, and a fixed end cap 31 is threaded onto the upper end of the push plate 14. The lower end lug of the pressure tube 30 is located inside the fixed end cap 31. A tapered hole that fits against the tapered arc outer wall of the tapered rod 38 is provided in the inner cavity of the tapered hole semi-ring 32. A fourth spring 37 is provided at the lower end of the lifting groove 29. The upper end of the fourth spring 37 abuts against the lower end face of the tapered rod 38. A third spring 36 is installed laterally in the sliding groove 35. The third spring 36 is sleeved on the crossbar 34, and the end of the third spring 36 is pressed against the outer wall of the tapered hole semi-ring 32. The elastic force of the fourth spring 37 is greater than that of the third spring 36.

[0054] When the push plate 14 is pushed, the cone rod 38 is lowered by squeezing the pressure tube 30 with the thumb. The fourth spring 37 is compressed, so that the pressure of the cone rod 38 on the cone hole half ring 32 disappears. Driven by the third spring 36, the cone hole half ring 32 slides to the inside of the push plate 14, driving the pressure block 33 to retract, thereby facilitating the push plate 14 to slide in the transverse slide groove 18.

[0055] When the push plate 14 is pushed to the slot 40 position, the pressure tube 30 is released. Under the action of the fourth spring 37, the cone rod 38 rises. Through the extrusion of the cone surface, the pair of symmetrically distributed cone hole half rings 32 are extruded and slid outward. The third spring 36 is extruded, driving the pressure block 33 to extend to the outside of the sliding groove 35, and then to the slot 40, forming a vertical misaligned engagement to achieve the purpose of stable positioning.

[0056] During reset, the pressure tube 30 is squeezed again to reset the pressure block 33, thereby releasing the misaligned connection and facilitating the reset and sliding of the push plate 14. After reset, the pressure tube 30 is released, and under the action of the fourth spring 37, the pressure block 33 is driven to extend outward again, so that the pressure block 33 presses against the inner wall of the transverse slide groove 18, achieving the purpose of laterally squeezing and fixing the push plate 14, preventing the push plate 14 from sliding freely in the transverse slide groove 18 and causing damage to the data interface 4.

[0057] A method for using a business virtual account management encryption / decryption device, the method comprising the following steps:

[0058] S1: First, select the corresponding connector 9 according to the type of the decrypted account. Rotate the outer shell 2 to rotate the connector 9 to the angle position corresponding to the connector 8.

[0059] S2: When in use, push the push plate 14 to slide and pull the front end of the data interface 4 to the outside of the front shell 1, and simultaneously pull the pull rope 16. Use the pull rope 16 to pull the card seat 21 to slide along the circumference of the arc groove 22, and drive the folded data cable 15 to rise and straighten.

[0060] S3: During the upward movement of the card holder 21, the traction rope 12 is stretched synchronously, causing the T-shaped plate 10 to slide laterally. After being pulled, the outer shell 2 slides and fits against the front outer shell 1, thereby allowing the connecting connector 8 to be electrically connected to the corresponding connecting seat 9, thus realizing the connection of the data circuit.

[0061] 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.
