Abstract

The utility model relates to a trigger-type alarm theftproof bag which can identify theft means that a thief lacerates a leather bag with a blade. Owing to a complete circuit loop used by the theftproof leather bag, when the leather bag is lacerated by the blade, electrodes are touched, and thus the alarm is automatically delayed for twenty seconds. The utility model has the advantages of artful design, novel, reasonable conception, optimistic production prospect and favorable market potential, consumers can like the utility model, and the utility model is especially suitable for the production of a backpack, a satchel, a school bag, a travelling bag, a luggage carrier, a purse, etc.

Description

Antitheft bag

The utility model relates to a kind of antitheft (anti-cutting) suitcase device, especially can discern the burglar and scratch the trigger-type alarming anti-theft bag that the leather bag is committed theft with blade.

At present, known antitheft packing is equipped with a lot, and it is antitheft to adopt locking formula and remote control system mostly.This its complex structure of class anti-theft device, volume is big and weight is heavier, is difficult for producing, and occupies very big space in suitcase.

The purpose of this utility model provides a kind of antitheft bag, and it is not only in light weight, and its result is simple at the face shaping that does not destroy the leather bag, easily the trigger-type anti-theft device leather bag of producing in batches.

The purpose of this utility model is achieved in that and is provided with very thin very rare double layer of metal net in the leather bag, and one deck is anodal, and one deck is a negative pole.Join at wire netting has power supply and alarm.In the ordinary course of things, both positive and negative polarity electric forming circuit loop is in static no duty, when the burglar commits theft, scratching leather encrust and wire netting with metal blade touches both positive and negative polarity and is connected by blade, circuit loop forms, the delayed alarm device starts report to the police (continuity 20 seconds of reporting to the police), and there is something special for prompting suitcase owner, reaches real antitheft purpose.

Owing to adopt such scheme, produced antitheft bag adopts standard components and parts (on sale on the delayed alarm device market), and is simple in structure, easily produces in batches.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is circuit theory diagrams of the present utility model.A among the figure is the delayed alarm device; B is the trigger electrode positive pole of delayed alarm device; C is the trigger electrode negative pole of delayed alarm device; D is a power unit.

Fig. 2 is the part section structural map of antitheft bag embodiment.

Fig. 3 is the A-A partial sectional view of Fig. 2.

Among Fig. 2 and Fig. 3:

The 1st, the outer leather layer of leather bag (decorating leather)

The 2nd, the skin of wire netting circuit (positive pole)

The 3rd, insulating barrier (separation layer)

The 4th, the internal layer of wire netting (negative pole in the circuit)

The 5th, the internal layer of leather bag (general leather)

The 6th, the delayed alarm device

The 7th, power pack (battery)

In embodiment illustrated in fig. 2, wire netting outer 2 and wire netting internal layer 4 and delayed alarm device 6 and power pack 7 form complete circuit loop.Touch inner layer metal net utmost point polar circuit and just form complete circuit when the burglar scratches the skin of leather bag and wire netting skin (comprising insulating barrier) with blade, anti-theft device is just started working, and alarm equipment alarm continues 20 seconds, and alarm work is just finished.

Establishing power unit in the antitheft bag of the utility model is toggle formula power supply, and under the normal condition, anti-theft device is in static no duty, have only burglar's blade to scratch wire netting after, touch the two poles of the earth, automatic processing circuit forms circuit loop, warning device is just started working.Therefore, antitheft bag has the advantage of the power consumption of need not (the leather bag normally uses not power consumption, and blade touches just power consumption of the two poles of the earth when having only chance to commit theft).

The antitheft bag design of the utility model is ingenious, novel, and sound construction is disguised strong.Have and make simply, cheap, easy to use, the advantage of good anti-theft effect.And be fit to produce knapsack, stride bag, school bag, traveling bag, luggage case and wallet or the like.For people go on a journey shopping, travel, being on home leave provides safety guarantee.Antitheftly be surrounded by very wide prospect of production and very optimistic market potential, and be bound to be liked by consumers in general and approve that great promotional value is arranged ...

Claims (4)

1, a kind of antitheft wrapping in the decorative leather (1), by wire netting (2,4), insulating barrier (3), power supply (battery) (7) and delayed alarm device (6) are linked in sequence.It is characterized in that: antitheft bag is that a cover touches the formula burglar alarm.

2, antitheft bag according to claim 1 is characterized in that: two trigger electrodes of delayed alarm device (6) are connected to the ectonexine wire netting of antitheft bag respectively, form positive and negative polarities.
