[0027] Specifically, when in use, through the coordinated use of the protective shell 1, the protective door 2, the electronic smart lock 3, the lock tongue 4 and the card slot 5, the USB interface on the computer can be shielded and protected when not in use by authorized operators, preventing some people who do not have computer operating authority from plugging and unplugging USB flash drives into the USB interface of the computer, thereby achieving the USB anti-plugging function, ensuring that the data on the computer is not easily stolen, greatly reducing the risk of data leakage, and through the setting of the fastening part, the U disk can be assisted in pressing when the authorized person operates it, which can avoid the loosening of the connection between the U disk and the USB interface, thereby improving the connection stability between the U disk and the USB interface.
[0028] The fastening part includes a movable plate 6 slidably installed in the protective shell 1, a knob 72 is slidably installed on the movable plate 6, a screw 7 is threadedly connected to the movable plate 6, one end of the screw 7 is rotatably connected to the pressure plate 71, and the other end of the screw 7 is fixedly connected to the knob 72.
[0029] Specifically, when an authorized operator needs to reinforce the U disk, he first moves the movable plate 6 to the U disk plugged into the USB interface, then rotates the knob 72 to drive the screw 7 to rotate. Under the action of the thread, the screw 7 drives the pressure plate 71 to move toward the U disk and assists in pressing the U disk, which can prevent the connection between the U disk and the USB interface from loosening, thereby improving the connection stability between the U disk and the USB interface.
[0030] Guide grooves 61 are provided on both sides of the inner wall of the protective shell 1 , and guide blocks 62 are fixedly connected to both ends of the movable plate 6 , and the guide blocks 62 are connected to the guide grooves 61 in a transversely sliding manner.
[0031] Specifically, by providing the guide groove 61 and the guide block 62 , the movable plate 6 can be guided, thereby facilitating adjustment of the position of the pressing plate 71 .
[0032] The movable plate 6 is slidably connected to a guide rod 8 , and the pressing plate 71 is fixedly connected to the guide rod 8 .
[0033] Specifically, by providing the guide rod 8 , the pressing plate 71 can be guided to prevent the pressing plate 71 from rotating along with the screw rod 7 .
[0034] The protective shell 1 is connected to the tube shell 9, and a fan 91 is fixedly installed inside the tube shell 9. A through opening 92 is opened on the protective shell 1, wherein a shielding net 93 is fixedly installed on the tube shell 9, and the inlet end of the fan 91 faces the through opening 92, and the exhaust end of the fan 91 faces the shielding net 93.
[0035] Specifically, when operated by authorized personnel, the air in the protective shell 1 can be continuously discharged by starting the fan 91. The flowing air can take away the heat on the U disk and the USB interface to achieve the purpose of heat dissipation and cooling, preventing the U disk and the USB interface from overheating and being damaged, which helps to increase the service life of the U disk and the USB interface. In addition, by setting the shielding net 93, the exhaust port of the tube shell 9 can be shielded to improve safety of use.
[0036] The four corners of the protective shell 1 are fixedly connected with mounting plates 21 , and mounting holes 22 are formed through the mounting plates 21 .
[0037] Specifically, by providing the mounting plate 21 and the mounting hole 22 , the protective shell 1 can be conveniently installed and fixed at the USB interface of the computer host, and installation from the inside of the protective shell 1 can also improve the overall protection effect of the anti-plugging mechanism.
[0038] Working principle: When using this USB anti-plug mechanism, first, the protective shell 1 is fixedly installed on the USB interface of the computer host through the mounting plate 21. When a person with computer operation authority uses it, he can enter the correct password on the electronic smart lock 3. The electronic smart lock 3 can control the lock tongue 4 to retract and disengage from the card slot 5, thereby releasing the limit on the protective door 2. The operator can then open the protective door 2 and connect the USB flash drive to the USB interface for use;
[0039] When the USB port of the computer is not in use, the protective door 2 can be closed, the lock tongue 4 can be slid over the frame of the protective shell 1 and inserted into the card slot 5, and a closed space can be formed between the protective shell 1 and the protective door 2, so as to shield and protect the USB port on the computer, and prevent people who do not have computer operation authority from plugging in or unplugging a USB flash drive from the USB port of the computer, thereby achieving the function of USB anti-plugging, ensuring that the data on the computer is not easily stolen, and greatly reducing the risk of data leakage.
[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
