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.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a universal anti-theft lock for portable electronic devices, which can be applied to anti-theft lock holes of various specifications, thereby being convenient to use and low in cost.

The second steering block 33B is slidably disposed on the buckle section 111B along the extending direction of the buckle section 111B, and forms a second push surface 331B; the second push surface 331B is preferably inclined to the buckle section 111B A plane in the direction of extension. The second pushing surface 331B can relatively slide against the first pushing surface 321B of the first steering block 32B. The sliding of the first turning block 32B toward the second turning block 33B along the extending direction of the lock head section 112B drives the second turning block 33B to slide toward the head end opening 101B; thereby, the operating member 21B of the lock head assembly 20B moves along the lock head section 112B. The movement of the second steering block 33B will be converted into the movement of the second steering block 33B along the buckle section 111B, so that the operating member 21B can drive the components in the buckle section 111B when the channel 11B is bent at a large extent or even vertical.

In this embodiment, the elastic member 31B is disposed between the second diverting block 33B and the spreading rod 40B, and makes the second diverting block 33B and the spreading rod 40B tend to move away from each other, but this is not the case However, the elastic member 31B may also be disposed between the first steering block 32B and the operating member 21B.

The elastic member 31B of this embodiment can also be replaced with two mutually exclusive magnetic members 31A, and the two mutually exclusive magnetic members 31A can be respectively disposed on the second turning block 33B and the spreading rod 40B, and the first turning block 32B and the spreading rod 40B. The rod 40B, or the first pushing surface 321B of the first steering block 32B and the second pushing surface 331B of the second steering block 33B.

To sum up, in the present invention, the operating member 21 of the lock head assembly 20 indirectly drives the opening lever 40 through the displacement absorbing mechanism 30 , and the movement of the opening lever 40 will gradually spread the engaging portions 55 of the two electronic devices. (that is, moving away from each other), whereby when the operating member 21 is moved to the locked position, the displacement absorbing mechanism 30 can continue to push the opening rod 40 in the direction of the head end opening 101 to make the two electronic device engaging parts 55 is stretched until the clip 50 is limited by the width of the anti-theft lock hole 91 , so that the present invention is suitable for anti-theft lock holes 91 of various widths to achieve the effect of stepless adjustment. In other words, when the operating member 21 is moved to the same locking position, the two clips 50 of the present invention can be stretched and fixed in a plurality of unfolded positions, unlike the traditional anti-theft locks 50 that can only be held up It can be opened to a single unfolding position, so that the present invention can be applied to anti-theft lock holes 91 of various widths.
