Description

The bag burglar alarm

Technical field

The utility model relates to alarm, concrete is the bag burglar alarm that bag or knapsack are used.

Background technology

Along with the raising of people's living standard and the continual renovation of life style, the personnel amount of travelling outdoors and working is on the increase, nearly all hold bag in people's hand, knapsack or traveling bag riding public transportation means or the public place of coming in and going out, this has been quotidian thing.Yet always have extremely others not think the business that the right way is specially done the thief in the society, how crowded when in people's occasions, the thief can seize the opportunity and stage an armed rebellion, and opens people's the bag or the slide fastener of knapsack and steals the wealth of the inside, and this phenomenon takes place continuously.

At present society goes up for antitheft and had produced corresponding anti-theft appliance already, antitheft door for example, and safety box, antitheft car etc., but the bag burglar alarm is also never arranged.

Summary of the invention

The purpose of this utility model is not provide a kind of bag burglar alarm at bag or the antitheft warning device of knapsack are arranged at present as yet.

The technical scheme that adopts is:

The bag burglar alarm, comprise bag and alarm, described bag is the bag that general top is equiped with nylon zipper, its design feature is: the bottom of bag medial surface is provided with a little pocket, the both sides up and down of bag top nylon zipper are respectively arranged with two metal line of metal wire group M, and two metal line are corresponding to be connected with the alarm output lead;

Described alarm comprises K switch, buzzer BZ, battery E and control circuit board is housed in box body and the box body that described control circuit board comprises chip U1 and chip U2; The positive pole of battery E connects 4 pin of chip U1 and an end of 8 pin and resistance R 1 simultaneously through K switch, the other end of resistance R 1 connects 6 pin of chip U1 and the anode of 7 pin and capacitor C 2 simultaneously, the negative terminal of capacitor C 2 connects the negative pole of battery E, 2 pin of chip U1 and the negative pole wiring of battery E are all the alarm output lead, the 2 pin output leads of chip U1 connect the metal line of antitheft metal wire group M, and another metal line of antitheft metal wire group M is connected with the negative pole of battery E; Between two metal line of antitheft metal wire group M and connect capacitor C 1; 1 pin of chip U1 connects the negative pole of battery E, 5 foot meridian capacitor C3 connect the negative pole of battery E, 3 pin of chip U1 are connected with the power positive end of chip U2, and the power supply negative terminal of chip U2 connects the negative pole of battery E, and the output of chip U2 is connected by the two ends of lead with buzzer BZ.

The utility model is skillfully constructed, and is simple in structure, and consumptive material is few, and alarm is small and exquisite, with low cost, safe in utilization, can prevent effectively that article are stolen.The installing valuables carried very convenient, safety when the suitable people of the utility model went out.

The specific embodiment

Embodiment

The bag burglar alarm, comprise bag 1 and alarm 2, described bag is the bag 1 that general top is equiped with nylon zipper, the bottom of bag 1 medial surface is provided with a little pocket 4, the both sides up and down of bag top nylon zipper 6 are respectively arranged with two metal line of metal wire group M, and two metal line are corresponding to be connected with the output lead 7 of alarm 2;

Described alarm 2 comprises K switch, buzzer BZ, battery E and the control circuit board 3 that is equipped with in box body 5 and the box body 5, and described control circuit board 3 comprises chip U1 and chip U2; The positive pole of battery E connects 4 pin of chip U1 and an end of 8 pin and resistance R 1 simultaneously through K switch, the other end of resistance R 1 connects 6 pin of chip U1 and the anode of 7 pin and capacitor C 2 simultaneously, the negative terminal of capacitor C 2 connects the negative pole of battery E, 2 pin of chip U1 and the negative pole wiring of battery E are all the alarm output lead, the 2 pin output leads of chip U1 connect the metal line of antitheft metal wire group M, and another metal line of antitheft metal wire group M is connected with the negative pole of battery E; Between two metal line of antitheft metal wire group M and connect capacitor C 1; 1 pin of chip U1 connects the negative pole of battery E, the 5 foot meridian capacitor C3 of chip U1 connect the negative pole of battery E, 3 pin of chip U1 are connected with the power positive end of chip U2, and the power supply negative terminal of chip U2 connects the negative pole of battery E, and the output of chip U2 is connected by the two ends of lead with buzzer BZ.

1,2 pin of chip U1 are output as the burglar alarm external lead wire 7 of bag 1, connect respectively on two metal line of anti-theft wire group M, and two metal line are installed in the both sides up and down of nylon zipper 6, and alarm 2 is installed in the little pocket 4 of bag 1 lower inside.

Chip U1 is the time-base integrated circuit chip, the model that adopts is NE555, it and resistance R 1, capacitor C 1, C2 forms single-shot trigger circuit, circuit is in stable state when having no talent the antitheft metal wire group M of both sides up and down that touches nylon zipper 6 on the bag at ordinary times, be the 3 pin output low levels of chip U1, alarm chip U2 does not work, during any metal line of the antitheft metal wire group M the thief touches bag nylon zipper 6 near, the human body sensing electromotive force inputs to negative pulse of 2 pin of chip U1, monostable is triggered, 3 pin of chip U1 become high level by original low level to be made alarm chip U2 obtain power supply and works, and output makes buzzer send alarm sound.
