A computer lock is a physical anti-theft device made primarily of alloy cable, commonly used to protect computer equipment, such as laptops and projectors. Its core function is to secure the device to an external object via a combination of steel cable and lock, preventing unauthorized movement or theft.
The hardware structure typically includes an alloy lock shell, a wound steel cable, and locking components. The steel cable is usually 1.5-1.9 meters long and covered with PVC or polyvinyl chloride for enhanced durability. Locking methods include key, 4-digit combination, or T-shaped rotary lock design, compatible with the keyholes of thin and light laptops. Some products integrate a retractable steel cable and an online key control management system, supporting key replacement. Software-wise, it can be expanded to include power-on permission control, file encryption, and peripheral device disabling functions. Patented technology solves the problems of complex disassembly of traditional locks, and the use of a fully mechanical transmission structure improves reliability.
