Abstract
The utility model relates to a theft-proof bag with an electronic alarm, particularly a theft-proof bag with an electronic alarm for preventing a leather layer of a bag from being cut open, which comprises an outer wrapped leather layer, an inner lapping cloth layer and a zipper. The utility model is characterized in that the position between the outer wrapped leather layer and the inner lapping cloth is provided with a metal film composite layer that is identical to the outer wrapped leather layer. The metal film composite layer is composed of two stannum films divided by an intermediate insulation layer. The inner lapping cloth layer is provided with an electronic alarm plate that is respectively connected with the inner stannum film and the outer stannum film of the metal film composite layer by a foot 1 and a foot 2 of a music chip I C 1 in the inner lapping cloth layer. A foot 4 of the music chip IC1 is connected with a base of a triode G. The S of a sounder is connected between an emitter electrode of the triode G and a collecting electrode. In addition, a chain and a drawing buckle of the zipper are separately connected with the foot 1 and the foot 2 of the music chip IC1. Therefore, the leather layer of the bag can be prevented from being cut open and the bag can be prevented from being stolen because the zipper is pulled open.
Description
The utility model relates to a kind of antitheft bag, especially refers to the electronic warning and anti-theft bag of the cortex pilferage of anti-cutting bale broken.
At present, the theft-prevention structure kind of briefcase, handbag, knapsack is a lot, but the zip alarming anti-theft that great majority are confined to wrap can not reach the comprehensive alarming anti-theft to bag.
In view of this, the purpose of this utility model provides a kind of electronic warning and steals bag, and whole foreskin and zip position all are provided with the warning sensing element, and simple in structure, to account for volume little.
The purpose of this utility model is achieved in that it comprises the bag exodermis, internal lining cloth layer, zip, it is characterized in that: between bag exodermis and internal lining cloth layer, be provided with and the metal film composite bed that wraps the identical size of exodermis, this metal film composite bed is to be made of the two tin films that intermediate insulating layer separates, pin 1 with its musical film IC1 is set on internal lining cloth layer, 2 two ends connect respectively in the metal film composite bed, the electronic warning plate of outer tin film, and the pin 4 of musical film IC1 connects the base stage of triode G, connect an acoustical generator S between the emitter and collector of triode G, in addition, the chain of zip and draw button also to use the pin 1 of electric wire edge joint musical film IC1 respectively, 2.
Above-mentioned acoustical generator is loudspeaker or piezoelectric ceramic piece.
Because adopt such scheme: any position of various bags is cut all can report to the police, safe and reliable again, cheap.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram of the utility model exemplary embodiments.
Fig. 2 is the circuit theory diagrams of the utility model exemplary embodiments.
Among the figure: 1 bag exodermis, 2 internal lining cloth layers, 3 zips, 4 metal film composite beds, 5 electronic warning plates.
Metal film composite bed 4 is and bag exodermis 1 or the identical intermediate layer of internal lining cloth layer 2 sizes, connect (bonding or sew up) at encrust 1 inner face edge with the edge, the metal film that belongs to a kind of conduction, this metal film composite bed 4 are to be made of the two tin films that middle plastic foil insulating barrier separates.
Electronic warning plate 5 is mainly by triode G, musical film IC1 and acoustical generator S(loudspeaker or piezoelectric ceramic piece) be formed by connecting.Electronic warning plate 5 is fixedly connected on internal lining cloth layer 2 bottoms (or the pocket of putting thereon is interior).
Pin 1,2 edge joints of musical film IC1 are to the inside and outside tin film of metal film composite bed 4, pin 4 connects the base stage of triode G, and pin 3 connects emitter stage, pin 2 edge joint colelctor electrodes again, the emitter stage of triode G connects dc source (battery), power switch K, until the pin 1 of edge joint to musical film IC1, between the emitter and collector of utmost point pipe G, connect an acoustical generator S.The pin 1,2 of musical film IC1 also connects the chain of zip 3 with electric wire respectively and draws and buckle simultaneously.
The operating principle of present embodiment:
When the power turn-on switch with after locking zip 3, as long as must puncture metal film composite bed 4 with the bale broken exodermis 1(that lancinates) or draw back zip 3, pin 1,2 circuit of musical film IC1 are connected, and the electric current on the circuit sends tens of seconds sound at once by acoustical generator S.
When owner used bag, as long as disconnecting power switch K, i.e. power supply ended.
Claims (2)
1, a kind of electronic warning and anti-theft bag comprises the bag exodermis, internal lining cloth layer, zip, it is characterized in that: between bag exodermis and internal lining cloth layer, be provided with and the metal film composite bed that wraps the identical size of exodermis, this metal film composite bed is to be made of the two tin films that intermediate insulating layer separates, pin 1 with its musical film IC1 is set on internal lining cloth layer, 2 two ends connect respectively in the metal film composite bed, the electronic warning plate of outer tin film, and the pin 4 of musical film IC1 connects the base stage of triode G, connect an acoustical generator S between the emitter and collector of triode G, in addition, the chain of zip and draw button also to use the pin 1 of electric wire edge joint musical film IC1 respectively, 2.
2,, it is characterized in that by the described electronic warning and anti-theft bag of claim 1: above-mentioned acoustical generator be perverse or piezoelectric ceramic piece.
