Abstract

The utility model relates to a theftproof and alarming pocket. The utility model has the advantages of simple structure, small size, and safe work., wherein, a snap used as a short switch can be a general metal snap or can be realized by some other methods, an alarming circuit is only a musical integrate circuit, and a buzzer is operated under the voltage of 1.5 v. Accordingly, the utility model is easy to popularize and generalize, and the utility model can very effectively reduce or prevent money and objects carried by a person from being stolen.

Description

Anti-theft alarming pocket

The utility model relates to a kind of burglar alarm that is used for packsacks, the various pockets of bag.

The antitheft case and bag of prior art, mainly implement antitheft to whole case and bag, and concerning most of user, what need were antitheft mainly is money and some valuables, their volume is generally all little, and existing antitheft case and bag, when taking general article, all can report to the police or adopt certain operations to eliminate warning at every turn, as eliminating warning, so not only taken electric weight but also inconvenience, and the volume of this class anti-theft device is all bigger with the releasing cipher switch, the cost height, power consumption is big, and use and voltage are also higher, common more than 3 volts.And, mainly adopt methods such as light control alarm, touch mode alarm to reach antitheft purpose for more existing antitheft wallets, so its less stable easily produces false alarm.Sometimes can not play antitheft effect, reaching dark place at night as the light-controlled antitheft wallet is to report to the police.Particularly also fail pocket is directly played antitheft effect.In addition, the price of the carry-on anti-theft device of present some is higher, and integrated level is not high again, complex structure, broad masses' demand in can't expiring.

The purpose of this utility model is in order to overcome the shortcoming of prior art, to make carry-on money and goods antitheft more effective, uses more conveniently, and cost reduces, and has designed such burglar alarm pocket, and it has plays antitheft effect to all article in the pocket.

The utility model is realized by following method, the micro alarm device of packing in pocket.Draw two short-circuit lines from warning circuit, these two short-circuit lines are hidden in two bag face interlayers with certain wire laying mode respectively.Pack into the snap-fastener of a metal of sack lid place, two parts of snap-fastener connect two short-circuit lines of drawing respectively.The metal snap-fastener that covers when sack is during two extension line short circuits of warning circuit, and warning device does not send the sound.Open pocket if draw back snap-fastener, when perhaps being hidden in two short-circuit lines in the bag face and being cut off, alarm just sends the sound.Pocket is opened or all will sends chimes of doom when being cut like this, has played antitheft purpose.

Such burglar alarm pocket is contained in knapsack, the bag, or directly does packing bag for clothes, lining bag etc., just can prevent the generation of the stolen incident of carry-on money and goods effectively.To public's money and goods safety rise actively, effective function.

Below just describe principle of work of the present utility model in detail in conjunction with Figure of description.

Fig. 1 is the electrical schematic diagram of burglar alarm.

Fig. 2 is the outside drawing of burglar alarm pocket.

With reference to Fig. 1, wherein (1) is short-circuit line, and K is a short circuiting switch, and Y is a warning circuit for hummer M, adopts 1.5 volts of DC power supply.Its principle of work is, when short circuiting switch K or short-circuit line (1) open circuit, warning circuit M receives a signal, and warning circuit M works immediately, exports a string signal, makes hummer Y send chimes of doom.If short circuiting switch K or short-circuit line (1) are opened a way always, chimes of doom will be successively.Because warning circuit M adopts the CMOS integrated circuit, so when short circuiting switch K or short-circuit line (1) short circuit, the supply current of 1.5 volts of batteries has only about 3uA approximately, consumed power not substantially.And the maximum current when reporting to the police also has only about 10mA.So will not take out by battery at ordinary times, needn't install power switch additional yet.No. 7 batteries of a general joint can use about 1 year, and power consumption is minimum.

With reference to Fig. 2, wherein (2) are warning device, include 1.5 volts of batteries (generally use No. 7 pond or button cell) and warning circuit and hummer.(3) be metal snap-fastener or magnetic attracting device, be equivalent to the short circuiting switch K in the accompanying drawing 1.(4) be a bag face, be concealed with the short-circuit line (1) that is equivalent in the accompanying drawing 1 in its interlayer, the short-circuit line that do not fracture when sack is is often opened and closed, its adopts multiply yarn envelope curve to make.The principle of work of burglar alarm pocket is, opens sack or cuts a bag face (4) when cutting off the multiply yarn envelope curve that is hidden in wherein simultaneously when drawing back snap-fastener (3), and alarm (2) just sends alerting signal, plays to prevent stolen purpose.The burglar alarm pocket can be other shape.The metal snap-fastener can be other shape.Warning device can be other shape.Short-circuit line in the bag face interlayer can be arranged by various forms.

Claims (4)

1, a kind of burglar alarm pocket is characterized in that being made of pocket and warning device.

2, by the described burglar alarm pocket of claim 1, it is characterized in that described warning device is to be made of short-circuiting means and warning circuit.

3,, it is characterized in that described short-circuiting means is to be made of metal snap-fastener that is installed in sack and the short-circuit line that is sewn in bag face by claim 1 and 2 described burglar alarm pockets.

4,, it is characterized in that described short-circuit line adopts the multiply yarn envelope curve by claim 1 and 3 described burglar alarm pockets.
