In order to achieve the above object, the utility model adopts the following technical scheme:

a simple anti-theft alarm device for a notebook computer comprises a notebook computer body, an anti-theft box, a lock head, an anti-theft rope, a built-in power supply, an alarm, a protective resistor and a short-circuit wire; wherein: the anti-theft box is fixedly installed inside the notebook computer body, one end of an anti-theft rope is fixedly connected to the anti-theft box, the other end of the anti-theft rope is fixedly connected to a lock head, the lock head is fixedly connected to the anti-theft box, the anti-theft box is internally composed of a built-in power supply, an alarm, a protection resistor and a short circuit wire, the built-in power supply, the alarm and the protection resistor are fixedly installed inside the anti-theft box, the built-in power supply, the alarm and the protection resistor are connected in series through wires.

A simple anti-theft alarm device for a notebook computer, wherein: the short-circuit wire is positioned inside the anti-theft rope.

A simple anti-theft alarm device for a notebook computer, wherein: the short connecting wire is embedded in the anti-theft rope in a double-strand manner.

Compared with the prior art, the utility model discloses a simple and reliable structure, after the theftproof rope is cut by force, can cut the short-circuit line at siren both ends simultaneously for the siren sounds, plays the alarming function.

Drawings

Fig. 1 is a schematic diagram of the structure of the present invention.

Fig. 2 is a circuit wiring diagram inside the anti-theft box of the utility model.

Fig. 3 is a structural diagram of the short-circuit wire inside the anti-theft rope.

Reference numerals: the anti-theft alarm comprises a notebook computer body 1, an anti-theft box 2, a lock head 3, an anti-theft rope 4, a built-in power supply 21, an alarm 22, a protective resistor 23 and a short-circuit wire 24.

Detailed Description

The following embodiments are further described with reference to the accompanying drawings.

Embodiment 1, please refer to fig. 1 to 3, a simple anti-theft alarm device for a notebook computer, comprising a notebook computer body 1, an anti-theft box 2, a lock head 3, an anti-theft rope 4, a built-in power supply 21, an alarm 22, a protection resistor 23, and a short-circuit wire 24; wherein: inside anti-theft box 2 fixed mounting and notebook computer organism 1, 4 one ends rigid couplings of theftproof rope are on anti-theft box 2, the other end rigid coupling is on tapered end 3, tapered end 3 rigid coupling is on anti-theft box 2, anti-theft box 2 is inside to comprise built-in power supply 21, alarm 22, protection resistor 23, short-circuit wire 24, built-in power supply 21, alarm 22, the equal fixed mounting of protection resistor 23 are inside anti-theft box 2, and the three establishes ties for the return circuit that switches on through the wire, short-circuit wire 24 connects in parallel at the both ends of alarm 22.

Embodiment 2, please refer to fig. 1 to 3, a simple anti-theft alarm device for a notebook computer, wherein: the short-circuit wire 24 is positioned inside the antitheft rope 4 and plays a role of protecting the short-circuit wire 24. The rest is the same as example 1.

Embodiment 3, please refer to fig. 1 to 3, a simple anti-theft alarm device for a notebook computer, wherein: the short connecting wire 24 is folded into two strands and embedded in the anti-theft rope 4, and normal unlocking is not interfered. The rest is the same as example 1.

The working principle is as follows: in normal use, the lock head 3 is opened through a key, the anti-theft rope 4 can be separated from the lock head 3, unlocking can be achieved, if the anti-theft rope 4 is cut off forcibly, the short connecting wire 24 inside the anti-theft rope can be cut off at the same time, and after the short connecting wire 24 is cut off, the alarm 22 is powered on and then gives an alarm.
