Further, described LED, buzzer are all located on braces, and LED is located at the position that eyes can be seen, be convenient to people and can observe the alarm signal that lamp sends, buzzer is located at close to people's ear place, is convenient to the sound that people's ear can hear warning.

Further, described copper wire is located between knapsack crust and liner, evenly arranges.

Further, described switch can be selected as required, as: inductive switch, gravity switch, press button, slide switch etc.

Further, described power circuit is all located at the position not affecting knapsack and normally use.

Further, the gap of 2-3 centimetres is left in described slide fastener both sides, is convenient to mobile phone and is placed in bag passing through of earphone cords such as wearing wired earphone call or listen to the music.

The utility model advantage has:

1. structure is simple, cost is low, be easy to the manufacturing;

2. be easy to operation and safe and reliable.

In the drawings, 1. button cell, 2. switch, 3.LED lamp, 4. buzzer, 5.PNP triode, 6. resistance, 7. copper wire, 8. inclusion, 9. slide fastener, 10. braces, 11. copper wire pads.

Detailed description of the invention

The utility model is described in further detail for embodiment plan given below; but can not be interpreted as it is restriction to the utility model protection domain; those skilled in the art to nonessential improvement and adjustment more of the present utility model, still belong to protection domain of the present utility model according to the utility model content.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6,1. button cell, 2. switch, 3.LED lamp, 4. buzzer, 5.PNP triode, 6. resistance, 7. copper wire, 8. inclusion, 9. slide fastener, 10. braces, 11. copper wire pads.

Embodiment one (singly takeing on bag)

A kind of novel anti-theft knapsack, comprise button cell 1, switch 2, LED 3, buzzer 4, PNP triode 5, resistance 6, copper wire 7, inclusion 8 and some wires, it is characterized in that: a kind of novel anti-theft inside backpacks is provided with the power circuit be made up of some wires, the power supply of power circuit is button cell 1, button cell 1 positive pole is connected with switch 2, switch 2 and LED 3, copper wire 7 is connected, LED 3 is in parallel with copper wire 7, copper wire 7 is connected with the base stage of PNP triode 5, copper wire 7 is evenly distributed on the positive and negative inclusion 8 of knapsack, on the slide fastener 9 that the same position that is all welded in 7 one, the copper wire of positive and negative inclusion 8 matches, when slide fastener 9 close copper wire pad 11 contact time, line conduction, LED 3 is connected with buzzer 4, buzzer 4 is connected with the emitter stage of PNP triode 5, the colelctor electrode of PNP triode 5 is connected with button cell 1 negative pole, colelctor electrode and the base stage section of PNP triode 5 are parallel with resistance 6, prevent short circuit and provide low electricity frequently for PNP triode 5 base stage.
