Description

Technical Field

[0001] This utility model relates to a device for preventing accidental insertion of USB flash drives, and more particularly to a device for preventing the incorrect insertion of external USB flash drives into an internal computer. Background Technology

[0002] In specialized fields, confidentiality is a red line; a leak can cause irreparable damage to an enterprise. Within a company, an external USB drive of unknown origin can be inserted into an internal computer, allowing for the rapid download of sensitive internal data. In classified units, internal computers are typically managed using dedicated USB drives; the computer can only be powered on and used when the corresponding secure USB drive is inserted; otherwise, access to the system is impossible. While this reduces the occurrence of leaks to some extent, it cannot completely prevent the insertion of external USB drives into internal computers, and leaks that do occur often have serious consequences.

[0003] For certain special products, the content generated by their computers should not be disseminated externally, such as radar products and certain data testing instruments. For these types of products, it is best to take measures to ensure that only dedicated USB flash drives can be connected, while general non-secret USB flash drives cannot be inserted. Summary of the Invention

Detailed Implementation

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 13 As shown, this utility model discloses an internal computer anti-misinsertion device for external USB flash drives, comprising a USB flash drive end device 1, a connecting part 2, and an anti-misinsertion part 3. The anti-misinsertion part 3 is fixed to the USB flash drive port 4 of the internal computer 5 via the connecting part 2. The connecting part 2 of this utility model can be fixed by screws or glued, preferably glued, such as using 3M glue for the connecting part 2.

[0030] like Figure 3 and Figure 4 As shown, the USB flash drive terminal device 1 includes a USB flash drive 1-1, a transition ring 1-2, and protrusions 1-3, which fit together tightly to ensure the USB port is installed correctly and in the correct orientation. The surface of the transition ring 1-2 is treated with a wear-resistant finish. Three protrusions 1-3 are located on the surface of the transition ring 1-2, on the left, right, and top sides respectively; or on the left, right, and bottom sides. The left and right protrusions function to rotate the connecting rod 3-4 when the connecting device 3 is inserted. The top protrusion 1-3 mates with a groove in the upper connecting seat 3-3 to position the USB flash drive terminal device 1 in the direction of rotation. If the top protrusion 1-3 is positioned at the bottom, the corresponding upper connecting seat 3-3 is also positioned at the bottom; this technical improvement is a change in the vertical position. Figure 3 Only the lower part is shown in the illustration. This utility model includes at least 1-3 protrusions on the left and right sides, and preferably protrusions are also provided on the upper and lower sides.

[0031] This utility model uses the connecting part 2 to adhere the anti-misalignment insertion part 3 to the internal computer 5, ensuring that the USB flash drive port 4 is aligned vertically and horizontally with the left and right sealing plates 3-9. (e.g.) Figure 1 ,like Figure 2).

[0032] like Figures 5 to 7 As shown, the anti-misalignment insertion part 3 of this utility model includes a screw 3-1, a lower connecting seat 3-2, an upper connecting seat 3-3, a connecting rod 3-4, a rear baffle 3-5, an A-type spring 3-6, a connecting rod pin 3-7, a pin 3-8, left and right sealing plates 3-9, and a rope 3-10. Assembly method (e.g.) Figure 6 ,like Figure 7 Rope 3-10 is connected to connecting rod 3-4 and left and right sealing plates 3-9. Connecting rod pins 3-7 and 3-8 are inserted into lower connecting seat 3-2. Rear baffle 3-5 is fixed to lower connecting seat 3-2. Left and right sealing plates 3-9 are inserted into the gap between rear baffle 3-5 and lower connecting seat 3-2, and rope 3-10 is... Figure 7 As shown, after bypassing pin 3-8, connecting rod 3-4 is installed onto connecting rod pin 3-7. Two type A springs 3-6 are then pressed... Figure 7 Insert the lower connector 3-2 into the gap between the rear baffle 3-5 and the lower connector 3-2 as shown. Connect the lower connector 3-2 and the upper connector 3-3 with two screws 3-1, ensuring that the pin 3-8 is inserted into the upper connector 3-3, and that there is no gap between the upper connector 3-3 and the lower connector 3-2. After assembly, it should look like... Figure 5 As shown. Figure 7 As shown, the rear baffle 3-5 and the upper connecting seat 3-3 have grooves at the corresponding positions of the upper protrusion 1-3.

[0033] The working principle of this utility model is as follows: When no USB flash drive is inserted, the device uses the elastic force of type A springs 3-6 to close the left and right sealing plates 3-9, preventing ordinary USB flash drives from being inserted into the USB flash drive port 4 of the internal computer 5 (e.g., Figure 9 ,like Figure 12 When the USB flash drive terminal device 1 of this utility model is inserted, the connecting rod 3-4 of this device rotates due to the load of the left and right protrusions 1-3 of the USB flash drive terminal device 1. The force is transmitted to the left and right sealing plates 3-9 through the rope 3-10. The force is greater than the elastic force of the A-type spring 3-6, and the left and right sealing plates 3-9 will automatically open, allowing the USB flash drive terminal device 1 to pass through the device and be inserted into the internal computer 5 (e.g., ...). Figure 8 ,like Figure 11 ,like Figure 13 ).

[0034] This utility model achieves the linkage of the mechanism within a limited space by relying on components such as connecting rod 3-4, rope 3-10, and spring. Compared with other technical solutions, it has the advantages of reliability, lightness, compactness, and low material cost.

[0035] This utility model device achieves the following objectives: First, from a technical perspective, after using this device, all other non-classified USB flash drives cannot be inserted into the internal computer 5, and the USB flash drive end device 1 can be inserted and removed smoothly, stably, and reliably. Second, from a management perspective, it eliminates the risk of employees violating confidentiality regulations, prevents leaks of information about the internal computer 5 from confidential units and departments, and improves the level of confidentiality management.
