Abstract

The utility model relates to an anti-thief handbag with self-defence function; the utility model is characterized in that a radio receiver and a high-voltage pulser are arranged in the handbag; the radio receiver can receive a remote signal sent by a transmitter outside the handbag. The receiver can alarm and produce high-pressure electric shock pulse in 20-30 seconds when the distance between the handbag and the transmitter exceeds the warning range; then the thief is forced to put down the handbag in hand. The utility model is suitable to people for outgoing and traveling, families, and offices; besides, the utility model can be used for storing valuables and tickets. The utility model has the advantages of less power consumption, low cost.

Description

Anti-thief handbag with self-defence function

The utility model relates to the safe bag that uses in a kind of daily life and the work, specifically is meant a kind of antitheft bag with the self-defence function.

Now, using safe handbag miscellaneous in the society.The employing coded lock that has, but can not be stolen together by the company's of preventing bag.So, just set up charge switch, the handbag of alarm devices such as tongue tube, even useful iron chains is attached on the wrist.These annexes can only play basically and remind owner thief-proof, and the facility that the also influence that has is used and carried still exists many disadvantages and deficiency.

The purpose of this utility model provides a kind ofly can not only send the stolen alarm sound, can also discharge the safe antitheft bag that the high-voltage pulse electric shock has the self-defence function to stealing the bag person.

The utility model is to realize like this; Its external form and common bag are same or similar, characteristics are to be equipped with to receive radio receiver and the high-voltage pulse generator of installing the remote signal of sending in the emitter in the bag outside in bag, and the output of high-voltage pulse generator then is connected with the woven wire of evenly mating formation in the surface wall of bag.

During use, volume has only the emitter of half cigarette case size to be placed on usually in the pocket of owner's dress with oneself, can not discharge high frequency radio signal to the space, and the receiver that is installed in the utility model receives.This receiver also is the warning device of antitheft school bag, can adjust fence coverage as required.When the distance between owner's (being transmitter) and the bag was no more than fence coverage (for example 3～6 meters radius), bag was not alarmed.In case bag is stolen, steal the hand-held bag of bag person and leave and exceed fence coverage, the receiver in this bag will send warning tone immediately, with remind owner or on every side people note deadly condition.If stealing the bag person does not still put down bag and continues hand and hold bag and leave, the shell that sends whole bag in 20～30 seconds of alarm behind the sound by with on high voltage pulse about 200V, force and steal that the bag person puts down bag and flee in terror also is that bag has the self-defence function.When owner goes in front of the bag, also be emitter in the fence coverage of receiver, the alarm sound and pulse voltage Lock-out, owner can arbitrarily make things convenient for the use bag.This performance also can remind owner that the Shi Buhui that goes out loses bag.

Characteristics of the present utility model are by the transmission of radio high-frequency signal and receive the safety that monitors the bag warning, once have things stolen, just make high-voltage pulse electricity on the bag band soon, and this voltage only can or not cause great bodily injury to the people with electric shock about 200 volts.The design concept novelty, practicality.This bag is particularly suitable for going out handling affairs or the travel staff uses, and uses it as the financial and accountancy personnel that often go to bank to send money or to withdraw the money, and can strengthen safe, reliable sense.The utility model also can be placed on family or the office fixed location is used to collect valuables, at this moment, should be placed on emitter from the not far hidden place of bag, guards against it.So the utility model is applied widely, using method is varied, is a kind of new type of safe bag.This device is noted reducing cost and power consumption on circuit design, adopts transistor and No.5 cell to make the energy, and all the cost of electronic devices and components is convenient to knock down price and apply about 45 yuan.Its size dimension can be made seriation, is convenient to select for use.

Below in conjunction with accompanying drawing, continue to introduce the utility model.

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is an electrical schematic diagram of the present utility model.Wherein a is transmitter circuitry figure, and b is receiver circuit figure, and C is the circuit diagram of high-voltage pulse generator.

The external form that shows the utility model and common bag among Fig. 1 is same or similar, also coded lock 1 can be installed, at the tank surface wall planted agent woven wire 2 of evenly mating formation, receiver and impulse generator all are made in the printed board 3, be contained in the hidden part of bag inboard, wherein the output of impulse generator is connected with woven wire 2, also is connected with metal angle bead on the angle around the bag simultaneously, and the output of receiver then is connected with the loudspeaker 4 of alarm sound generator.

Emitter system uses transistor T ₁And T ₂The auto-excitation type high-frequency flip-flop of forming, circuit diagram is seen Fig. 2 a, its volume only is half cigarette case size, can be placed on owner with oneself or other hidden part at one's side.The circuit of receiver is in addition improved on common wireless circuit, and wherein T3, L and C1, C2 form superregenerative formula detecting circuit, and L and C1 resonance transmit so that frequency-selecting receives in the operating frequency of emitter.This signal after T4, T5 amplify and form voltage doubling rectifing circuit by C3, D1 and D2, the bistable trigger-action circuit that goes T6, T7 two pipes to form.When signal is enough strong, the T6 conducting, then the base potential of T7 is very low, and T7 ends, and the audio amplifier circuit that transistor T 8 and transformer B form is not worked yet.In case signal weakens, when T6 is ended, the T7 conducting of at once overturning, it is alert and make the relay J adhesive that then chimes of doom is sent in T8 work.Potentiometer W is used to adjust receiver sensitivity, just adjusts its fence coverage size.Usually fence coverage is about 3～6 meters.When relay J adhesive action, its normally opened contact J1-1 closure on the high-voltage pulse generator then, this circuit begins pulse transformer B1 charging, and high-voltage pulse output was just arranged after 20～30 seconds.Woven wire discharge by casing produces the electric shock effect.If do not need high-voltage pulse generator work, can open K switch 2.Receiver highly sensitive, the power consumptive province.Static working current when guarding against at ordinary times is no more than 0.5 milliampere, and the operating current during warning is about 2 milliamperes.Adopt four joint No.5 cells, can work about two months usually.

Claims

1, a kind of antitheft bag with self-defence function, external form and common bag be same or similar to be is characterized in that evenly mating formation in the surface wall of bag woven wire, the output of the high-voltage pulse generator in this woven wire and the bag is connected, radio receiver device also is housed in bag, and this device can receive to install in what the emitter in the bag outside sent and shake the control signal.
