Abstract

An anti-theft soft package is similar to a common soft package in appearance and mainly comprises a bag body 1, an alarm switch 2, a control switch 3, an electronic alarm system 4, an insulating layer 5 and a conductor layer 6, wherein when a master goes out and a thief wants to cut a bag to take objects, the conductor layer is communicated with the inner conductor layer and the outer conductor layer to alarm in a short circuit mode when cutting the conductor layer to the insulating layer, and when the thief wants to open a zipper to take the objects, a button type alarm switch is firstly required to be opened, and then a circuit is disconnected to alarm in a broken circuit mode. The utility model discloses simple structure, the function is reliable, convenient operation, can extensively be used for knapsack, handbag, file package, photographic package, travel bag etc..

Description

A kind of antitheft Soft Roll

The utility model belongs to civilian case and bag and makes the field, comprises knapsack, handbag, photography bag, file bag, traveling bag etc.Most of in the past Soft Roll does not have burglary-resisting system, little burglary-resisting system, or the easy false alarm of electronic system, or inclusion rigidity is too big.

A kind of light softness that the purpose of this utility model designs with regard to being to overcome above-mentioned deficiency, the Soft Roll guard against theft and alarm system of the reliable in function that the short circuit of opening circuit is all reported to the police.

The purpose of this utility model is to realize like this.

Described antitheft Soft Roll is mainly by inclusion 1, warning switch 2, gauge tap 3, electronic warning system 4.Insulating barrier 5 is formed with conductor layer 6, and thief is got thing as desiring steamed sandwich, cut to conductor layer during with insulating barrier two conductor layers communicate and short-circuit alarming; Get thing when the thief desires to open zip, at first must open press-button type warning switch, 2, at this moment circuit disconnects and breaking alarming, owner Kai Bao opens gauge tap 3, at this moment arbitrarily operation and silent from the little slide fastener pocket in inboard.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is a basic block diagram of the present utility model

Fig. 2 is a double team layer structure chart

Fig. 3 is circuit theory diagrams

Among the figure: 1, inclusion, 2, the warning switch, 3, gauge tap, 4, electronic warning system,

5, insulating barrier, 6, conductor layer.

Warning switch 2 is a snap lock of slide fastener end in fact among Fig. 1, it when entering the state of alert conducting shape, non-owner desires to open, and promptly disconnecting circuit is breaking alarming, gauge tap 3 is the master switch of circuit, be located in the little slide fastener pocket of bag one side, switch closes, and system can work, switch disconnects, and system quits work.Electronic warning system 4 is information processing centres, and information after treatment becomes audible alarm, in time notifies owner, and your bag meets with danger.

Fig. 2 is a Soft Roll wall sandwich, wraps that two conductor layers 6 are separated by insulating barrier 5 and insulation all the time, and outer plate is connected with electronic warning system 4 respectively in it, and when thief cuts to two conductor layers with the blade steamed sandwich, blade makes two conductor layer conductings, and circuit is implemented warning.

Fig. 3, this circuit are a short circuit, breaking alarming circuit, and two gate circuits of integrated circuit CD4001 are formed clocked flip-flop, and two other gate circuit is formed oscillating circuit and BG ₁, BG ₂The common double-audio signal generator of forming, as shown, at ordinary times 2., 3. hold to be connected in-to rise, integrated package CD4001 is pin output high level 3., the double-audio signal generator is not worked, loudspeaker is noiseless, and when 1. 2. during terminal shortcircuit, CD4001 is the pin output low level 3., the circuit starting of oscillation, the loudspeaker sounding, simultaneously, capacitor C ₁Through resistance R ₁When charging to 4001 threshold voltages, 3. pin is exported high level, the circuit failure of oscillation, and loudspeaker stops sounding.In addition, when 2. 3. end opens circuit, the integrated 3. pin output low level of CD4001 of determining, the work of double-audio signal generator, the loudspeaker sounding is realized reporting to the police.

Claims

1, a kind of antitheft Soft Roll, outward appearance is identical with normal packet, mainly is made up of inclusion 1, warning switch 2, gauge tap 3, electronic warning system 4, insulating barrier 5, conductor layer 6.It is characterized in that: be embedded with two layers of conductor layer, 6, two conductor layers 6 between the bag wall and be insulated layer 5 insulation, and be connected to respectively on the electronic warning system 4 again.

2, according to the described conductor layer 6 of claim 1, can be metal object, also can be nonmetal thing.
