Multifunctional bag against stealing

The utility model relates to class articles for daily use, relates in particular to a class official document, the portable antitheft bag of travelling.

At present, the bag of being sold on the market that anti-theft feature is arranged also seldom, Chinese patent CN2104573 discloses a kind of " bidirectional alarming, anti-theft security suitcase ", this suitcase adopts remote controller, the suitcase circuit, the anti-function latching circuit of carrying, compositions such as alien frequencies bidirectional transmit-receive code signal circuit, aspect antitheft, thief-proof, the anti-loss good effect is being arranged, but, it is this that " antitheft, thief-proof, the safe suitcase circuit structure of bidirectional alarming complexity, cost height generally are used to adorn a large amount of money or valuables such as gold and silver, jewelry.

The purpose of this utility model provides a kind of simple in structure, and cost is low, the multifunctional burglary-resistant bag that purposes is wide.

The technical solution of the utility model is to realize like this.

A kind of multifunctional burglary-resistant bag, comprise inclusion (1), clad (2), handle (3), snap close (4) is up and down arranged respectively on clad (2) and the inclusion (1), (5), inclusion has burglar alarm in (1), burglar alarm is by warning device box (8), anti-cutting cloth gauze (6) is formed, anti-cutting cloth gauze (6) is located at soft of inclusion (1) on every side and easily cuts the place, the warning device circuit comprises battery main switch K1, trigger BG1, noncontacting switch controllable silicon Vs, warning IC amplifier BG2, loudspeaker (7), trigger BG1 base stage is to a short-circuit line AE being arranged, anti-cutting cloth gauze (6) between the ground, anti-hold liquid K switch 7, anti-K switch 3, prevent taking K switch 6 by force all on this short-circuit line, anti-K switch 3 is by the last snap close (4) on the clad (2), and the following snap close (5) on the inclusion (1) is common to be constituted.

Battery main switch K1, functional select switch K5, K6 prevents that taking K switch 2 by force is located on the clad (2).

Battery main switch K1 is a plug-in type power supply master switch, and power supply disconnects when plug inserts, power connection when extracting, anti-take by force K switch 2 for the plug-in type switch of battery main switch functions reversed.

Anti-hold liquid K switch 7 is made up of two switches, and the shell of each switch is the glass or the plastic casing of sealing, and the inside liquid is pure water, light salt brine, light alkali fire, rare-acid water, and electrode is enclosed in two ends, and the central axis of two switches intersects and is 90 degree, and polyphone.

Can also establish a reed in handle (3) termination as the anti-K switch 4 of carrying, the anti-K switch 4 polyphones one functional select switch K5 that carries, K4, K5 are connected between noncontacting switch controllable silicon Vs anode and the trigger BG1 emitter stage, and functional select switch K5 is located on the clad (2).

Burglar alarm principle of the present utility model is: functional select switch is connected power supply, when bag is cut or plunder, breakdown, takes, all makes when carrying that short-circuit line AE opens circuit in the circuit, in circuit, form bias voltage, trigger trigger BG1, starting noncontacting switch controllable silicon Vs, operating voltage is provided for warning IC amplifier BG2, makes loudspeaker send chimes of doom.

Good effect of the present utility model is: simple in structure, cost is low, and function is complete, anti-cutting, anti-takes, anti-ly takes by force, anti-ly opens, anti-ly puies forward five-function, and low in energy consumption, quiescent dissipation is 1-5 μ A.Adopt noncontacting switch controllable silicon Vs, highly sensitive, good reliability.
