Description

Technical Field

[0001] The present invention relates to the technical field of digital information storage devices, and specifically to a secure storage device for digital information management and its usage method. Background Art

[0002] Digital information management refers to the process of effectively collecting, organizing, storing, retrieving, analyzing, utilizing, and protecting the digital information resources of an organization or an individual by using modern information technology and management methods, so as to maximize the value of digital information, support decision-making, business operation, and innovation and development goals. Most of the above devices are located inside the computer room. After the operation is completed, the above results also need to be transmitted to the storage device.

[0003] Among them, in order to improve the transmission stability and speed, wired storage devices are mostly used. However, there is no corresponding protection device at the connection position between the wired storage device and the host. When the connection line shakes due to external force, the connection position will also loosen synchronously, thus affecting the transmission and storage of data, and even causing data loss. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a secure storage device for digital information management, including a base. Inside the wall of the base is fixedly connected a USB plug. On the side wall of the base are fixedly connected three inclined rack bars. Sliding on the outer walls of the three inclined rack bars is a sliding tube. Inside the wall of the sliding tube is fixedly connected three sliding columns;

[0005] A protection mechanism, which includes a USB socket, a fixing frame for restricting the sliding of the USB socket, an interaction frame, a first spring, an inclined surface, a transmission line, and a limiting component for restricting the sliding of the interaction frame;

[0006] The outer wall of the USB socket is slidably connected to the inner wall of the fixing frame. The outer wall of the fixing frame is fixedly connected to the inner wall of the sliding tube. The outer walls of the three sliding columns are slidably connected to the outer wall of the interaction frame. The side wall of the interaction frame is fixedly connected to the side wall of the first spring. The end of the first spring away from the interaction frame is fixedly connected to the side wall of the fixing frame. The side wall of the USB socket is fixedly connected to the side wall of the transmission line. The side wall of the interaction frame is fixedly connected to the side wall of the inclined block. Before use, install the base at the required position, ensure that the USB plug and the USB socket can be normally connected, and ensure that the transmission line between the interaction frame and the fixing frame is in a bent state, presenting the state as shown in Figure 3 state G in the figure. When data needs to be transmitted, slide the sliding tube closer to the USB plug. At this time, the sliding tube drives the USB socket into the USB plug through the fixing frame to complete the connection between the USB socket and the USB plug.

[0007] Preferably, the limiting component includes a support frame fixedly connected to the inner wall of the sliding tube. A prying plate is rotatably connected to the outer wall of the support frame. The top of the sliding tube is fixedly connected with an L-shaped plate, and a second spring is fixedly connected to the side wall of the L-shaped plate.

[0008] Preferably, the limiting component further includes three inclined plates rotatably connected to the inner wall of the through hole of the fixed frame. A torsion spring is fixedly connected to the inner walls of the three inclined plates. One end of the torsion spring away from the inclined plate is fixedly connected to the inner wall of the fixed frame. When an external rapid pulling force is transmitted to the USB socket through the transmission line, as Figure 3 shown, at this time, the transmission line will generate a pulling force to the right, forcing the transmission line to slide along the inner wall of the interaction frame. During this process, the torsion spring will force the end of the inclined plate to always closely adhere to the outer wall of the transmission line. When the transmission line moves horizontally, the three inclined plates will limit the movement of the transmission line, so that the external pulling force is transmitted to the interaction frame through the inclined plates, forcing the interaction frame to move outward along the outer wall of the sliding column. The outward moving interaction frame drives the inclined block to move outward synchronously, so that the inclined surface of the inclined block contacts one end of the prying plate, forcing the prying plate to tilt upward with the support frame as the center, and the other end of the prying plate swings downward, so that the end of the prying plate away from the inclined block moves downward into the inner wall of the inclined surface tooth bar, and the end of the prying plate close to the inclined block contacts the inner wall of the L-shaped plate, presenting a state as Figure 5 shown.

[0009] Preferably, the limiting component further includes a first support block fixedly connected to the top of the USB socket, and a second support block is fixedly connected to the bottom of the USB socket. One end of the second spring away from the L-shaped plate is fixedly connected to the outer wall of the prying plate. An adjusting component is slidably connected to the inner wall of the fixed frame. The prying plate will limit the sliding tube from continuing to move outward along the inclined surface tooth bar. Through the application of the above components, when the transmission line is subjected to a large pulling force, the pulling force of the transmission line will be transmitted to the inclined surface tooth bar and the base through the inclined plates, the interaction frame, and the prying plate, and the external rapid pulling force is offset by the base, avoiding the loosening of the USB socket and the USB plug caused by the external pulling force and affecting the transmission safety of the device.

[0010] Preferably, the adjusting component includes a first gear rotatably connected to the inner wall of the through hole of the fixed frame. The first gear is slidably connected to the inner wall of the fixed frame, and one end of the first gear away from the base is fixedly connected to the side wall of the interaction frame.

[0011] Preferably, the adjusting component further includes a second tooth bar slidably connected to the inner wall of the fixed frame. The side wall of the second tooth bar is meshed with the side wall of the first gear, and the side wall of the first gear is meshed with the side wall of the first tooth bar. A support block is fixedly connected to the side wall of the second tooth bar, and the side wall of the support block is fixedly connected to the side wall of the USB socket. A feeding component is fixedly connected to the side wall of the interaction frame. Utilizing the characteristic that the interaction frame slides outward under the pulling force of the transmission line, an adjusting component is arranged inside the device, presenting a state as Figure 8When the interactive frame moves outward, when the interactive frame drives the first rack to move to the right, the first rack drives the first gear to rotate, and the first gear forces the second rack to move to the right along the inner wall of the fixed frame. The second rack drives the USB socket to move horizontally towards the USB plug through the support block. Through the application of the above components, when an external rapid pulling force drives the interactive frame to move horizontally, at this time, the USB socket can still closely adhere to the inner wall of the USB plug, reducing the impact on the USB socket and the USB plug when the pulling force just occurs.

[0012] Preferably, the feeding component includes a limiting frame fixedly connected to the side wall of the interactive frame. A support column is rotatably connected to the inner wall of the limiting frame. A contact wheel is fixedly connected to the outer wall of the support column. A first sliding groove is formed in the side wall of the support column. A first inclined surface slider is slidably connected to the inner wall of the first sliding groove. A fourth spring is fixedly connected to the bottom of the first inclined surface slider. A third rack is fixedly connected to the side wall of the fixed frame.

[0013] Preferably, the feeding component further includes a toothed ring rotatably connected to the side wall of the limiting frame. A plurality of inclined surface blocks are fixedly connected to the inner wall of the toothed ring. An inclined groove is formed at one end of the support column away from the first sliding groove. The end of the fourth spring away from the first inclined surface slider is fixedly connected to the inner wall of the first sliding groove. When the interactive frame moves outward, the limiting frame will drive the toothed ring to move outward synchronously. At this time, the toothed ring will roll counterclockwise along the outer wall of the third rack, presenting a state as Figure 11 At this time, the toothed ring will drive the inclined surface blocks to rotate counterclockwise. During this process, the inclined surface of the first inclined surface slider contacts the inclined surface of the inclined surface block and forces the first inclined surface slider to slide downward along the inner wall of the first sliding groove, so that the rotation of the toothed ring cannot drive the support column and the contact wheel to rotate. After the external rapid pulling force disappears, at this time, the two first springs will drive the interactive frame to reset. During the reset process of the interactive frame, the toothed ring will rotate clockwise along the outer wall of the third rack. At this time, the flat surface of the inclined surface block will contact the flat surface of the first inclined surface slider, so that the toothed ring drives the support column and the contact wheel to rotate clockwise synchronously through the first inclined surface slider and the inclined surface block. The clockwise rotating contact wheel will force the transmission line to slide along the inner wall of the fixed frame towards the base at this time. Through the application of the above components, each time the device is subjected to an external pulling force, the rotating contact wheel will drive the transmission line to move a certain distance towards the base, avoiding damage to the outer skin of the transmission line after being subjected to multiple pulling forces at the same position.

[0014] Preferably, the feeding component further includes a U-shaped sliding carriage fixedly connected to the side wall of the limiting frame. A second inclined slider is slidably connected to the inner wall of the U-shaped sliding carriage. A fifth spring is fixedly connected to the bottom of the second inclined slider. One end of the fifth spring away from the second inclined slider is fixedly connected to the inner wall of the U-shaped sliding carriage. Taking advantage of the characteristics of the above-mentioned reset of the limiting frame and the contact wheel driving the transmission line to move, an inclined groove and a second inclined slider are provided inside the device. Among them, when the support column rotates clockwise, the inclined groove also rotates clockwise synchronously, which causes Figure 11 the position of the inclined groove in Figure 11 to move downward, and the inclined surface of the downward-rotating inclined groove will contact the inclined surface of the second inclined slider, forcing the second inclined slider to slide downward along the inner wall of the U-shaped sliding carriage; when the limiting frame moves outward and the toothed ring rotates counterclockwise, at this time the support column is not affected by the toothed ring and remains stationary, and the plane of the inclined groove will contact the plane of the second inclined slider, thereby ensuring that the support column can only rotate in one direction, avoiding the situation where when the first inclined block compresses the second inclined slider, the second inclined slider is blocked too much, resulting in the support column rotating counterclockwise and affecting the moving distance of the transmission line.

[0015] A usage method of a security storage device for digital information management includes the following steps:

[0016] S1: Install the device: Install the base at the required position, ensure that the USB plug and the USB socket can be normally connected, and ensure that the transmission line between the interactive frame and the fixed frame is in a bent state;

[0017] S2: Connect the components: When data needs to be transmitted, slide the sliding tube closer to the USB plug. At this time, the sliding tube drives the USB socket into the USB plug through the fixed frame to complete the connection between the USB socket and the USB plug.

[0018] The present invention has the following beneficial effects:

[0019] (1) Aiming at the problem that the external force is likely to cause the USB socket to become loose, a protection mechanism and a limiting component are provided inside the device. Before use, install the base at the required position, ensure that the USB plug and the USB socket can be normally connected, and ensure that the transmission line between the interactive frame and the fixed frame is in a bent state, presenting the state as shown in Figure 3 G in Figure 3 . When data needs to be transmitted, slide the sliding tube closer to the USB plug. At this time, the sliding tube drives the USB socket into the USB plug through the fixed frame to complete the connection between the USB socket and the USB plug; when an external rapid pulling force is transmitted to the USB socket through the transmission line, as shown in Figure 3As shown, at this time, the transmission line will generate a pulling force to the right, forcing the transmission line to slide along the inner wall of the interaction frame. During this process, the torsion spring will force the end of the inclined plate to always closely adhere to the outer wall of the transmission line. When the transmission line moves horizontally, the three inclined plates will restrict the movement of the transmission line, so that the external pulling force is transmitted to the interaction frame through the inclined plates, forcing the interaction frame to move outward along the outer wall of the sliding column. The outward-moving interaction frame drives the inclined block to move outward synchronously, so that the inclined surface of the inclined block contacts one end of the prying plate, forcing the prying plate to tilt upward with the support frame as the center, and the other end of the prying plate swings downward, so that the end of the prying plate away from the inclined block moves downward into the inner wall of the inclined surface tooth bar, and the end of the prying plate close to the inclined block contacts the inner wall of the L-shaped plate, presenting as Figure 5 the state shown. At this time, the prying plate will restrict the sliding tube from continuing to move outward along the inclined surface tooth bar. Through the application of the above components, when the transmission line is subjected to a large pulling force, the pulling force of the transmission line will pass through the inclined plate, the interaction frame, and the prying plate, and finally be transmitted to the inclined surface tooth bar and the base. The base is used to offset the external rapid pulling force, avoiding the loosening of the USB socket and the USB plug caused by the external pulling force and affecting the transmission safety of the device.

[0020] (2) By utilizing the characteristic that the above interaction frame slides outward under the pulling force of the transmission line, an adjustment component is arranged inside the device, presenting as Figure 8 the state shown. When the interaction frame moves outward, when the interaction frame drives the first tooth bar to move to the right, the first tooth bar drives the first gear to rotate, and the first gear forces the second tooth bar to move to the right along the inner wall of the fixed frame. The second tooth bar drives the USB socket to move horizontally towards the USB plug through the support block. Through the application of the above components, when the external rapid pulling force drives the interaction frame to move horizontally, at this time, the USB socket can still closely adhere to the inner wall of the USB plug, reducing the impact on the USB socket and the USB plug when the pulling force just occurs.

[0021] (3) By utilizing the characteristic that the above interaction frame moves outward, a feeding component is arranged inside the device. When the interaction frame moves outward, the limiting frame will drive the toothed ring to move outward synchronously. At this time, the toothed ring will roll counterclockwise along the outer wall of the third tooth bar, presenting as Figure 11At this state, the gear ring will drive the inclined block to rotate counterclockwise. During this process, the inclined surface of the first inclined surface slider contacts with the inclined surface of the inclined block, and forces the first inclined surface slider to slide downward along the inner wall of the first sliding groove, so that the rotation of the gear ring cannot drive the support column and the contact wheel to rotate. After the external rapid pulling force disappears, the two first springs will drive the interaction frame to reset. During the reset process of the interaction frame, the gear ring will rotate clockwise and engage along the outer wall of the third gear rod. At this time, the flat surface of the inclined block will contact with the flat surface of the first inclined surface slider, so that the gear ring drives the support column and the contact wheel to rotate clockwise synchronously through the first inclined surface slider and the inclined block. The clockwise rotating contact wheel will force the transmission line to slide along the inner wall of the fixed frame towards the base. Through the application of the above components, every time the device is subjected to an external pulling force, the rotating contact wheel will drive the transmission line to move a certain distance towards the base, avoiding damage to the outer skin of the transmission line caused by multiple pulls at the same position.

[0022] (4) By utilizing the above characteristics of the reset of the limiting frame and the movement of the transmission line driven by the contact wheel, an inclined groove and a second inclined surface slider are provided inside the device. Among them, when the support column rotates clockwise, the inclined groove also rotates clockwise synchronously, which makes Figure 11 the position of the inclined groove move downward, and the inclined surface of the downward-rotating inclined groove will contact with the inclined surface of the second inclined surface slider, forcing the second inclined surface slider to slide downward along the inner wall of the U-shaped sliding frame; when the limiting frame moves outward and the gear ring rotates counterclockwise, at this time the support column is in a stationary state without being affected by the gear ring, and the flat surface of the inclined groove will contact with the flat surface of the second inclined surface slider, thus ensuring that the support column can only rotate in one direction, avoiding excessive resistance when the inclined block compresses the first inclined surface slider, resulting in counterclockwise rotation of the support column and affecting the moving distance of the transmission line.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Example 1, please refer to Figure 1 - Figure 7 , the present invention is a secure storage device for digital information management, including a base 1. A USB plug 11 is fixedly connected to the inner wall of the base 1. Three inclined rack bars 12 are fixedly connected to the side wall of the base 1. A sliding tube 13 is slidably connected to the outer walls of the three inclined rack bars 12. Three sliding columns 14 are fixedly connected to the inner wall of the sliding tube 13;

[0041] A protection mechanism 2, the protection mechanism 2 includes a USB socket 21, a fixing frame 22 for slidingly restricting the USB socket 21, an interaction frame 23, a first spring 24, an inclined surface 25, a transmission line 26, and a limiting component 3 for restricting the sliding of the interaction frame 23;

[0042] The outer wall of the USB socket 21 is slidably connected to the inner wall of the fixing frame 22. The outer wall of the fixing frame 22 is fixedly connected to the inner wall of the sliding tube 13. The outer walls of the three sliding columns 14 are slidably connected to the outer wall of the interaction frame 23. The side wall of the interaction frame 23 is fixedly connected to the side wall of the first spring 24. The end of the first spring 24 away from the interaction frame 23 is fixedly connected to the side wall of the fixing frame 22. The side wall of the USB socket 21 is fixedly connected to the side wall of the transmission line 26. The side wall of the interaction frame 23 is fixedly connected to the side wall of the inclined block 25. Before use, the base 1 is installed at the required position, and it is ensured that the USB plug 11 and the USB socket 21 can be normally connected, and it is ensured that the transmission line 26 between the interaction frame 23 and the fixing frame 22 is in a bent state, presenting the state of G in Figure 3 . When data needs to be transmitted, the sliding tube 13 is slid close to the direction of the USB plug 11. At this time, the sliding tube 13 drives the USB socket 21 to enter the USB plug 11 through the fixing frame 22, completing the connection between the USB socket 21 and the USB plug 11.

[0043] The limiting component 3 includes a support frame 31 fixedly connected to the inner wall of the sliding tube 13. A lever plate 32 is rotatably connected to the outer wall of the support frame 31. An L-shaped plate 33 is fixedly connected to the top of the sliding tube 13. A second spring 34 is fixedly connected to the side wall of the L-shaped plate 33.

[0044] The limiting component 3 further includes three inclined plates 35 rotatably connected to the inner wall of the through hole of the fixing frame 22. A torsion spring 36 is fixedly connected to the inner walls of the three inclined plates 35. One end of the torsion spring 36 away from the inclined plate 35 is fixedly connected to the inner wall of the fixing frame 22. When an external rapid pulling force is transmitted to the USB socket 21 through the transmission line 26, as Figure 3 shown, at this time, the transmission line 26 will generate a pulling force to the right, forcing the transmission line 26 to slide along the inner wall of the interaction frame 23. During this process, the torsion spring 36 will force the end of the inclined plate 35 to always closely adhere to the outer wall of the transmission line 26. When the transmission line 26 moves horizontally, the three inclined plates 35 will limit the movement of the transmission line 26, so that the external pulling force is transmitted to the interaction frame 23 through the inclined plate 35, forcing the interaction frame 23 to move outward along the outer wall of the sliding column 14. The outward moving interaction frame 23 drives the inclined block 25 to move outward synchronously, so that the inclined surface of the inclined block 25 contacts one end of the prying plate 32, forcing the prying plate 32 to tilt upward with the support frame 31 as the center, and the other end of the prying plate 32 swings downward, so that the end of the prying plate 32 away from the inclined block 25 moves downward into the inner wall of the inclined surface rack 12, and the end of the prying plate 32 close to the inclined block 25 contacts the inner wall of the L-shaped plate 33, presenting as Figure 5 the state shown.

[0045] The limiting component 3 further includes a first support block 37 fixedly connected to the top of the USB socket 21. A second support block 38 is fixedly connected to the bottom of the USB socket 21. One end of the second spring 34 away from the L-shaped plate 33 is fixedly connected to the outer wall of the prying plate 32. An adjusting component 4 is slidably connected to the inner wall of the fixing frame 22. The prying plate 32 will limit the sliding tube 13 from continuing to move outward along the inclined surface rack 12. Through the application of the above components, when the transmission line 26 is subjected to a large pulling force, the pulling force of the transmission line 26 will be transmitted to the inclined surface rack 12 and the base 1 through the inclined plate 35, the interaction frame 23, and the prying plate 32, and the external rapid pulling force is offset by the base 1, avoiding the loosening of the USB socket 21 and the USB plug 11 caused by the external pulling force and affecting the transmission security of the device.

[0046] Embodiment 2. Please refer to Figure 8 - Figure 13 . The present invention is a secure storage device for digital information management. On the basis of Embodiment 1, the adjusting component 4 includes a first gear 41 rotatably connected to the inner wall of the through hole of the fixing frame 22. The first gear 41 is slidably connected to the inner wall of the fixing frame 22. One end of the first gear 41 away from the base 1 is fixedly connected to the side wall of the interaction frame 23.

[0047] The adjusting component 4 further includes a second rack 43 slidably connected to the inner wall of the fixed frame 22. The side wall of the second rack 43 is meshed and connected to the side wall of the first gear 41. The side wall of the first gear 41 is meshed and connected to the side wall of the first rack 42. A support block 44 is fixedly connected to the side wall of the second rack 43. The side wall of the support block 44 is fixedly connected to the side wall of the USB socket 21. A feeding component 5 is fixedly connected to the side wall of the interaction frame 23. Utilizing the characteristic that the interaction frame 23 slides outward under the tension of the transmission line 26, an adjusting component 4 is arranged inside the device, presenting as Figure 8 the state shown in. When the interaction frame 23 moves outward, when the interaction frame 23 drives the first rack 42 to move to the right, the first rack 42 drives the first gear 41 to rotate, and the first gear 41 forces the second rack 43 to move to the right along the inner wall of the fixed frame 22. The second rack 43 drives the USB socket 21 to move horizontally towards the direction of the USB plug 11 through the support block 44. Through the application of the above components, when an external rapid tension drives the interaction frame 23 to move horizontally, at this time, the USB socket 21 can still closely adhere to the inner wall of the USB plug 11, reducing the impact on the USB socket 21 and the USB plug 11 when the tension just generates.

[0048] The feeding component 5 includes a limiting frame 51 fixedly connected to the side wall of the interaction frame 23. A support column 52 is rotatably connected to the inner wall of the limiting frame 51. A contact wheel 53 is fixedly connected to the outer wall of the support column 52. A first sliding groove 54 is formed in the side wall of the support column 52. A first inclined plane slider 55 is slidably connected to the inner wall of the first sliding groove 54. A fourth spring 56 is fixedly connected to the bottom of the first inclined plane slider 55. A third rack 513 is fixedly connected to the side wall of the fixed frame 22.

[0049] The feeding component 5 further includes a gear ring 57 rotatably connected to the side wall of the limiting frame 51. A plurality of inclined plane blocks 58 are fixedly connected to the inner wall of the gear ring 57. An inclined groove 59 is formed at one end of the support column 52 away from the first sliding groove 54. One end of the fourth spring 56 away from the first inclined plane slider 55 is fixedly connected to the inner wall of the first sliding groove 54. When the interaction frame 23 moves outward, the limiting frame 51 will drive the gear ring 57 to move outward synchronously. At this time, the gear ring 57 will roll meshingly counterclockwise along the outer wall of the third rack 513, presenting as Figure 11At this state, the gear ring 57 will drive the inclined block 58 to rotate counterclockwise. During this process, the inclined surface of the first inclined surface slider 55 contacts the inclined surface of the inclined block 58, and forces the first inclined surface slider 55 to slide downward along the inner wall of the first sliding groove 54, so that the rotation of the gear ring 57 cannot drive the support column 52 and the contact wheel 53 to rotate. After the external rapid pulling force disappears, at this time, the two first springs 24 will drive the interaction frame 23 to reset. During the reset process of the interaction frame 23, the gear ring 57 will rotate clockwise and engage along the outer wall of the third toothed rod 513. At this time, the flat surface of the inclined block 58 will contact the flat surface of the first inclined surface slider 55, so that the gear ring 57 drives the support column 52 and the contact wheel 53 to rotate synchronously clockwise through the first inclined surface slider 55 and the inclined block 58. At this time, the clockwise rotating contact wheel 53 will force the transmission line 26 to slide along the inner wall of the fixed frame 22 towards the base 1. Through the application of the above components, each time the device is subjected to an external pulling force, the rotating contact wheel 53 will drive the transmission line 26 to move a certain distance towards the base 1, avoiding damage to the outer skin of the transmission line 26 after being subjected to multiple pulling forces at the same position.

[0050] The feeding component 5 further includes a U-shaped sliding frame 510 fixedly connected to the side wall of the limiting frame 51. A second inclined surface slider 511 is slidably connected to the inner wall of the U-shaped sliding frame 510. A fifth spring 512 is fixedly connected to the bottom of the second inclined surface slider 511. One end of the fifth spring 512 away from the second inclined surface slider 511 is fixedly connected to the inner wall of the U-shaped sliding frame 510. Utilizing the characteristics of the reset of the above-mentioned limiting frame 51 and the movement of the transmission line 26 driven by the contact wheel 53, an inclined groove 59 and a second inclined surface slider 511 are arranged inside the device. Among them, when the support column 52 rotates clockwise, the inclined groove 59 also rotates clockwise synchronously, which makes Figure 11 the position of the inclined groove 59 move downward inside. The inclined surface of the downward-rotating inclined groove 59 will contact the inclined surface of the second inclined surface slider 511, forcing the second inclined surface slider 511 to slide downward along the inner wall of the U-shaped sliding frame 510; when the limiting frame 51 moves outward and the gear ring 57 rotates counterclockwise, at this time, the support column 52 is not affected by the gear ring 57 and remains stationary, and the flat surface of the inclined groove 59 will contact the flat surface of the second inclined surface slider 511, thereby ensuring that the support column 52 can only rotate in one direction, avoiding excessive resistance when the inclined block 58 compresses the first inclined surface slider 55, resulting in counterclockwise rotation of the support column 52 and affecting the moving distance of the transmission line 26.

[0051] The usage method of the secure storage device for digital information management includes the following steps:

[0052] S1: Install the device: Install the base 1 at the required position, ensure that the USB plug 11 and the USB socket 21 can be normally connected, and ensure that the transmission line 26 between the interaction frame 23 and the fixed frame 22 is in a bent state;

[0053] S2: Connecting component: When data needs to be transmitted, slide the sliding tube 13 closer to the USB plug 11. At this time, the sliding tube 13 drives the USB socket 21 into the USB plug 11 through the fixing bracket 22 to complete the connection between the USB socket 21 and the USB plug 11.

[0054] A specific application of this embodiment is as follows: Before use, install the base 1 at the required position, ensure that the USB plug 11 and the USB socket 21 can be normally connected, and ensure that the transmission line 26 between the interactive frame 23 and the fixing bracket 22 is in a bent state, presenting the state as Figure 3 shown in G. When data needs to be transmitted, slide the sliding tube 13 closer to the USB plug 11. At this time, the sliding tube 13 drives the USB socket 21 into the USB plug 11 through the fixing bracket 22 to complete the connection between the USB socket 21 and the USB plug 11; when an external rapid pulling force is transmitted to the USB socket 21 through the transmission line 26, as Figure 3 shown, at this time, the transmission line 26 will generate a pulling force to the right, forcing the transmission line 26 to slide along the inner wall of the interactive frame 23. During this process, the torsion spring 36 will force the end of the inclined plate 35 to always closely adhere to the outer wall of the transmission line 26. When the transmission line 26 moves horizontally, the three inclined plates 35 will limit the movement of the transmission line 26, so that the external pulling force is transmitted to the interactive frame 23 through the inclined plate 35, forcing the interactive frame 23 to move outward along the outer wall of the sliding column 14, and the outward moving interactive frame 23 drives the inclined block 25 to move outward synchronously, so that the inclined surface of the inclined block 25 contacts one end of the prying plate 32, forcing the prying plate 32 to tilt upward with the support frame 31 as the center, and the other end of the prying plate 32 swings downward, so that the end of the prying plate 32 away from the inclined block 25 moves downward into the inner wall of the inclined surface tooth bar 12, and the end of the prying plate 32 close to the inclined block 25 contacts the inner wall of the L-shaped plate 33, presenting the state as Figure 5 shown. At this time, the prying plate 32 will limit the sliding tube 13 from continuing to move outward along the inclined surface tooth bar 12. Through the application of the above components, when the transmission line 26 is subjected to a large pulling force, the pulling force of the transmission line 26 will be transmitted to the inclined surface tooth bar 12 and the base 1 through the inclined plate 35, the interactive frame 23, and the prying plate 32, and the base 1 is used to offset the external rapid pulling force to prevent the USB socket 21 and the USB plug 11 from loosening due to the external pulling force and affecting the transmission security of the device.

[0055] Utilizing the characteristic that the interactive frame 23 slides outward under the pulling force of the transmission line 26, an adjustment component 4 is provided inside the device, presenting the state as Figure 8When the interactive frame 23 moves outward, when the interactive frame 23 drives the first rack 42 to move to the right, the first rack 42 drives the first gear 41 to rotate, and the first gear 41 forces the second rack 43 to move to the right along the inner wall of the fixed frame 22. The second rack 43 drives the USB socket 21 to move horizontally towards the USB plug 11 through the support block 44. Through the application of the above components, when an external rapid pulling force drives the interactive frame 23 to move horizontally, at this time, the USB socket 21 can still closely adhere to the inner wall of the USB plug 11, reducing the impact on the USB socket 21 and the USB plug 11 when the pulling force just occurs.

[0056] Utilizing the above characteristics of the outward movement of the interactive frame 23, a feeding component 5 is provided inside the device. When the interactive frame 23 moves outward, the limiting frame 51 will drive the toothed ring 57 to move outward synchronously. At this time, the toothed ring 57 will roll counterclockwise along the outer wall of the third rack 513, presenting a state as Figure 11 At this time, the toothed ring 57 will drive the inclined block 58 to rotate counterclockwise. During this process, the inclined surface of the first inclined surface slider 55 contacts the inclined surface of the inclined block 58 and forces the first inclined surface slider 55 to slide downward along the inner wall of the first sliding groove 54, so that the rotation of the toothed ring 57 cannot drive the support column 52 and the contact wheel 53 to rotate; after the external rapid pulling force disappears, at this time, the two first springs 24 will drive the interactive frame 23 to reset. During the reset process of the interactive frame 23, the toothed ring 57 will rotate clockwise along the outer wall of the third rack 513. At this time, the flat surface of the inclined block 58 will contact the flat surface of the first inclined surface slider 55, so that the toothed ring 57 drives the support column 52 and the contact wheel 53 to rotate clockwise synchronously through the first inclined surface slider 55 and the inclined block 58. The clockwise rotating contact wheel 53 will force the transmission line 26 to slide along the inner wall of the fixed frame 22 towards the base 1 at this time. Through the application of the above components, each time the device is subjected to an external pulling force, the rotating contact wheel 53 will drive the transmission line 26 to move a certain distance towards the base 1, avoiding damage to the outer skin of the transmission line 26 after being subjected to multiple pulling forces at the same position.

[0057] Utilizing the above characteristics of the reset of the limiting frame 51 and the movement of the transmission line 26 driven by the contact wheel 53, an inclined groove 59 and a second inclined surface slider 511 are provided inside the device. Among them, when the support column 52 rotates clockwise, the inclined groove 59 also rotates clockwise synchronously, which makes Figure 11The position of the inclined slot 59 moves downward, and the inclined surface of the downwardly rotating inclined slot 59 will contact the inclined surface of the second inclined surface slider 511, forcing the second inclined surface slider 511 to slide downward along the inner wall of the U-shaped carriage 510; when the limiting frame 51 moves outward and the toothed ring 57 rotates counterclockwise, at this time the support column 52 is not affected by the toothed ring 57 and remains stationary, and the plane of the inclined slot 59 will contact the plane of the second inclined surface slider 511, so as to ensure that the support column 52 can only rotate in one direction, avoiding excessive resistance when the inclined surface block 58 compresses the first inclined surface slider 55, resulting in counterclockwise rotation of the support column 52 and affecting the moving distance of the transmission line 26.
