Description

Universal portable electronic device anti-theft lock

The invention relates to an anti-theft lock, especially an anti-theft lock for fixing portable electronic devices.

Portable electronic devices, such as notebook computers, are usually provided with anti-theft lock holes, whereby a special anti-theft lock can be combined with the portable electronic device to lock the portable electronic device on the table or display cabinet, so that the Anti-theft when displayed in shopping malls, or to allow users to temporarily leave their seats in public places (such as libraries) without worrying about theft.

The anti-theft lock hole is a through hole formed through the outer wall of the portable electronic device. One end of the anti-theft lock is fixed to the table or display cabinet through a steel cable, and the other end has a claw. The outer end of the claws can penetrate into the casing through the anti-theft lock hole, and can be propped open in the casing so that the claws are fixed in the anti-theft lock hole and cannot be pulled out, thereby fixing the electronic device on the table or display cabinet.

The anti-theft lock holes have various specifications, the opening widths of the anti-theft lock holes of different specifications are different, and the thickness of the outer wall of the casing of the portable electronic device is also different. However, the claws of each anti-theft lock can only be opened and fixed at a specific deployment position, that is, the claws can only be opened to a specific width, so each existing anti-theft lock can only be equipped with a specific anti-theft lock Using the keyhole is very troublesome and expensive to use. For example, once users buy laptops of different specifications, they must purchase new anti-theft locks; if a shopping mall displays a variety of laptops of different specifications at the same time, it is necessary to prepare multiple anti-theft locks with different specifications, resulting in troublesome use. and high cost.

More specifically, there are three major systems for laptop security locks: Kensington Slot™, Noble Wedge Slot™ and Kensington Nano Slot™. Kensington Slot™ adds rounded holes in addition to the standard square keyhole; Noble Wedge Slot™ adds 3mm*5mm square keyholes (such as DELL™ laptops) in addition to the wedge-shaped holes, and so on, there are a total of 5 keyholes above; After many field tests, it was found that the above 5 kinds of apertures are different due to the different specifications of notebook computers, such as thick and thin iron sheets for anti-theft keyholes. The pen motor body is thick and thin. The assembly distance between the anti-theft keyhole iron plate and the pen motor body is also different, which makes the anti-theft lock unusable.

Therefore, the anti-theft locks for portable electronic devices in the prior art need to be improved.
