Description

Technical Field

[0001] This utility model relates to the field of USB locks, and in particular to a data anti-theft USB lock. Background Technology

[0002] In modern computer systems, the security of USB interfaces has become increasingly important. With the widespread use of USB devices, the security threats they pose are also constantly increasing, including virus infections, data breaches, and virus attacks. To address these threats, a series of technical measures have been implemented to enhance USB interface security. Generally, disabling the auto-run function of USB interfaces in the motherboard BIOS can prevent viruses and malware from automatically executing through USB devices, thus preventing unauthorized USB device access. However, modifying the serial port in the BIOS requires a certain level of computer knowledge, and BIOS modifications necessitate a computer restart. In scenarios with multiple computers, such as school computer labs, modifying the BIOS on each computer is time-consuming and labor-intensive, and this protection method cannot protect against intruders who possess this technical skill.

[0003] To protect USB ports more effectively and conveniently, hardware security devices are needed. By completely occupying the USB ports on the computer case or motherboard, intruders are prevented from connecting other devices to the USB ports on the computer case or motherboard.

The top of the first lock body 41 and the second lock body 42 is used to latch the external memory 2. The snap-fit ​​assembly 5 is inserted into the top of the first lock body 41 and the second lock body 42 and is used to press the latching assembly 7 to latch the external memory 2. The locking assembly 9 is installed at the bottom of the first lock body 41 and the second lock body 42 and is used to lock the snap-fit ​​assembly 5. The bottom cover 6 is installed at the bottom of the first lock body 41 and the second lock body 42. One end of the key 1 is integrally formed with a lever 11 for moving the locking assembly 9 to unlock.

[0034] Reference Figure 4As shown, the locking assembly 7 includes a first locking plate 71, a second locking plate 72, a first locking spring 73, and a second locking spring 74. The first locking plate 71 and the second locking plate 72 are arranged horizontally parallel. The upper end of the first locking spring 73 abuts against the middle of the first locking plate 71 and is used to lift the first locking plate 71 to reset. The upper end of the second locking spring 74 abuts against the middle of the second locking plate 72 and is used to lift the second locking plate 72 to reset.

The first locking buckle 96 and the second locking buckle 97 are respectively inserted into the first buckle buckle 59 and the second buckle buckle 591, thereby locking the buckle assembly 5. This prevents the buckle assembly 5 from loosening its pressure on the buckling assembly 7 under the elastic force of the first buckle spring 51 and the second buckle spring 52, ensuring the buckling is secure. The component 7 secures the external memory 2's male connector. By using the lever 11 of the key 1 to move the connecting rod 93 towards the first locking pin spring 94 and the second locking pin spring 95, the first locking latch 96 and the second locking latch 97 respectively disengage from their obstruction of the first latching pin buckle 59 and the second latching pin buckle 591, thereby unlocking the buckle component 5. The buckle component 5 releases its pressure on the locking component 7, and the locking component 7 releases its latch on the external memory 2's male connector, allowing the external memory 2 to be removed.
