Abstract

The utility model relates to an anti-theft wallet which is composed of a wallet body, an alarm circuit, a direct-current power supply, a clamping body, a cipher switch, a clamping seat, etc., wherein, the clamping body and the cipher switch of the utility model are arranged on the clamping seat, and the clamping seat is arranged on the wallet body. The cipher switch is an eight-gear tap switch, and the clamping body is a two-stage switch. By cooperation of the two switches, the alarm circuit immediately gives alarm to effectively protect people's money from being lost as long as anyone take up the wallets except owners (even the wallets are not taken out from bag lids). The utility model has the advantages of reasonable structure and easy use, and can perform a unique role with the capacity for striking pickpockets.

Description

Anti-theft wallet

The utility model relates to a kind of wallet, particularly a kind of antitheft wallet.

The thing of stealing now wallet happens occasionally, and its general degree makes us hard to guard against, and especially current majority lose is not only wealth, often together with many certificates, the people is suffered heavy losses, and the pickpocket is at large.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides that a kind of anyone only need pick up the antitheft wallet that wallet promptly can be reported to the police at once except that owner.

The purpose of this utility model can reach by following measure: the utility model comprises inclusion, warning circuit, dc source, it is characterized in that: also have clamp, cipher switch, clamp is loaded on the inclusion 1 by holder, and cipher switch is loaded on the holder.

The purpose of this utility model can also reach by following measure: cipher switch is eight grades of tap switches, and wherein a～g contact links to each other, and is serially connected with between dc source and the warning circuit.Clamp is a two-stage switch, and its contact k, l interconnect, and link to each other with dc source, triode BG in contact i, j and the warning circuit ₁Emitter-base bandgap grading join.

Fig. 1 is the structural representation of utility model;

Fig. 2 is the circuit theory diagrams of utility model;

Fig. 3 is the STRUCTURE DECOMPOSITION figure of holder part;

Fig. 4 is the internal structure schematic diagram of clamp part.

With reference to Fig. 1～Fig. 3, the utility model is by inclusion 1, warning circuit 2, two miniature button cell of dc source 3(), clamp 4(two-stage switch), cipher switch 5(tap switch), formation such as holder 6.Holder 6 is contained on the inclusion 1, and clamp 4, close moving switch 5 then are loaded on the holder 6; Electronic circuit board also is loaded in the holder 6.Warning circuit 2 is by triode BG ¹, BG ₂, buzzing Y, resistance R ₁Deng composition, with reference to Fig. 4, when clamp 4 is in level,, can hold up the L contact of phosphorus bronze sheet by the V angle because the V angle of phosphorus bronze sheet exceeds horizontal line, disconnect this moment; If press lower clamp 4, because the elastic reaction of phosphorus bronze sheet, the L contact can be pushed down the J contact, and this moment is with L and J contacting.When clamping sack (wallet is put bag into), bagging is isolated i and k two contacts, and disconnect this moment, if clamp is extracted out, then i can contact with the k contact, connects circuit.

During actual the use, as press lower clamp 4, make the J contact in the two-stage switch contact with the L contact, if beat cipher switch at 0 grade of any shelves in addition this moment, circuit will be connected, warning circuit work, and buzzer Y will send chimes of doom; Whole wallet is not taken out from sack by lower clamp if having, the elastic force of clamp itself can make the i contact push down the k contact, and closing of circuit, buzzer can send chimes of doom equally.But, oneself need not when using to report to the police, at this moment as long as cipher switch is pushed the h shelves in order to meet wallet owner's will.Cipher switch has eight shelves, but 7 of the insides are interconnected, and a dumb contact h is only arranged.Utilize seven pseudo-switches can reach the function of cipher switch.

The utility model has following advantage compared to existing technology:

1. have the password setting function, as long as anyone picks up wallet (even wallet does not leave sack fully) except owner, namely report to the police at once, can effectively protect people's wallet can not lose.

2. rational in infrastructure, circuit is simple, and processing ease is easy to use, and cost is lower, can play the part of unique role on the ability of hitting the pickpocket.

Claims

1, a kind of antitheft wallet comprises inclusion 1, warning circuit 2, dc source 3, it is characterized in that: also have clamp 4, cipher switch 5, clamp 4 is loaded on the inclusion 1 by holder 6, and cipher switch 5 is loaded on the holder 6.

2, wallet according to claim 1 is characterized in that: cipher switch 5 is eight grades of tap switches, and wherein a～g contact links to each other, and is serially connected with between dc source 3 and the warning circuit 2.

3, wallet according to claim 1 is characterized in that: clamp 4 is two-stage switches, and its contact k, l interconnect, and links to each other with dc source 3, triode BG in contact i, j and the warning circuit 2 ₁Emitter-base bandgap grading join.
