The present invention relates to an anti-theft device for a portable computer, and more particularly, to an anti-theft device for a computer that can be operated without using a separate tool while using the computer.

The portable computer has a size that can be carried because it is intended to be used indoors or outdoors, and particularly has a structure in which the battery is stored to be used outdoors.

Such a portable computer is convenient to use because it can be moved to any place, but there is a problem that theft is concerned. Therefore, portable computers come with locks to protect them from theft, which are usually operated using a separate tool.

6 and 7 are diagrams for explaining the anti-theft device installed in the conventional portable computer, and the locking means 3 is provided inside the battery compartment 2 of the cabinet 1.

The locking means (3) locates the slider (5) in which the hole (4) is drilled into the cabinet (1), and the groove (6) into which the driver or the like can be inserted into the inner end of the slider (4). Forming.

The locking means 3 of this structure removes the battery from the battery compartment 2 and then inserts a separately prepared driver D into the groove 6 and pushes the slider outward so that the slider 5 protrudes outward. As a result, a hole (4) into which the lock or lock can be inserted is exposed.

By the way, the locking means of this type is inconvenient because it uses a separate tool and there is a problem that the computer must be turned off because the battery must be removed to use the locking means.

The present invention is devised to solve the problems of the prior art as described above, the object of the present invention can be used without using a separate tool, theft of a portable computer that can be used without turning off the power of the computer It is to provide a prevention device.

In order to realize this, the present invention, the extension of the knob which is installed to be retracted from the outside of the cabinet is rotatably supported by the bracket and is installed with a spring, this extension is installed to have a rotational force by the torsion spring In addition, it provides an anti-theft device of a portable computer, characterized in that the position control projection protruding to the outside configured to enter and exit the position control projection through the grooves drilled in the cabinet according to the rotation operation of the knob.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a portable computer with the anti-theft device according to the present invention installed, and shows that a knob 12 is installed between the battery compartment 10 and the disc entrance 11.

The position of the furnace part 12 provided in this embodiment is not limited, It can install suitably in the main surface part of a main body.

2 is a side cross-sectional view of the anti-theft device according to the present invention, wherein the extension portion 14 of the knob 12 penetrating the cabinet 13 has a rear end fixed to the inside of the cabinet 13. Is rotatably supported.

On the outer circumference of the extension portion 14 of the knob 12, two positioning protrusions 16 and 17 are integrally formed, and the positioning protrusions 16 and 17 are formed on the inner side of the cabinet 13. The rotation angle can be regulated by the stoppers 18 and 19 formed in the groove.

The cabinet 13 is formed with a groove 20 through which the position regulating protrusion 16 can come out. The groove 20 is located in the position regulating protrusion 16 as shown in FIG. It is formed at a position separated by a predetermined angle from.

The extension part 14 of the knob 12 has a spring 21 between the bracket 15 so as to receive a moving force at all times, and one end of the torsion spring 22 extends 14. ) And the other end is fixed to the bracket (15) to have a rotational force.

One side end of the torsion spring 22 passes through the bracket 15 so that the extension part 4 can move together when moving forward.

The position restricting projection 16 is provided with a hole 23 through which a locking device or a lock can be inserted, which is illustrated in the use example of FIG.

In the antitheft device of the present invention, the state of FIG. 2 is the same as the state of the knob 12 shown in FIG. 1, and maintains the state of FIG.

In this state, since the position regulating protrusion 16 is caught on the inner surface of the cabinet 13, the spring 21 does not protrude out of the cabinet 13 due to the spring force of the spring 21.

In this state, when the knob 12 is rotated counterclockwise, the torsion spring 22 rotates together with the torsional force, and the extension portion 14 rotates together. Will rotate.

At this time, when the position restricting projection 16 is a position facing the groove 20 as shown in Figure 4, the extension portion 14 is pushed out of the cabinet 13 by the elastic force of the spring 21. .

That is, as shown in FIG. 5, since the extension portion 14 is pushed out of the cabinet 13 together with the knob 12, the hole 23 drilled in the positioning regulator 16 is exposed. Through 23, lock the lock or lock.

Then, when you want to release the locking device to release the lock from the hole (23) and push the knob (2) into the cabinet 13, the position regulating projection (l6) is pushed in, at this time torsion spring (22) The torsional action of returns to the state of FIGS. 2 and 3.

As described above, the anti-theft device according to the present invention can protrude a position regulating protrusion capable of filling the lock only by pulling or pushing the knob, compared to the conventional method of releasing the locking means using a screwdriver or the like. There is the convenience of use, and in using the locking means can be operated without removing the battery, there is an advantage that can be convenient to operate the computer compared to the conventional method.

Claims (1)

The extension portion 14 of the knob 12, which is installed to be retractable from the outside of the cabinet 13, is rotatably supported by the bracket 15, and is elastically installed by the spring 21, and the extension portion 14 ) Is installed so as to have a rotational force by the torsion spring (22), and also the grooves drilled in the cabinet (13) in accordance with the rotation operation of the knob 12, the position regulating projections (16) and (17) protrudingly formed on the outer circumference. Anti-theft device of a portable computer, characterized in that configured to allow the position control projection (16) to enter and exit through (20).
