Abstract
The utility model discloses a scratch and theft prevention wallet, which comprises a wallet cover, a wallet inner bag and a wallet belt. The middle position of the wallet belt is provided with a metal hook, a metal wire is arranged in the wallet belt, and three metal wires are arranged on the wallet cover. Besides, the scratch and theft prevention wallet further comprises a chip CD 4011, a resistor, a capacitor, a diode, a triode, a loudspeaker and a power supply. The scratch and theft prevention wallet has the advantages that a user clamps the wallet on a waistband through the metal hook on the wallet belt, and once a thief cuts off the wallet belt or scratches the wallet cover, the loudspeaker can give out alarming sound at intervals.
Description
Technical field
The utility model relates to a kind of wallet, particularly has the wallet of anti-scratch, anti-theft feature.
Background technology
Wallet has become requisite article in people's life, yet stolen at present phenomenon takes place again and again.Many thieves are through stealing wallet or scratching wallet and obtain unexpected wealth, and it is bigger to make people lose.
Up to the present, lack an effectively wallet of anti-scratch, antitheft always.
Summary of the invention
The purpose of the utility model provides a kind of effectively anti-scratch, antitheft wallet.
The utility model is realized through following measure:
A kind of anti-scratch, antitheft wallet comprise wallet front cover and wallet inner bag, and it also comprises a wallet band in addition, and wallet band centre position is provided with a metal hanger, is provided with 1 in wire in the said wallet band, on said wallet front cover, is provided with 3 in wire.
A kind of anti-scratch, antitheft wallet; Also comprise chip CD4011, resistance, electric capacity, diode, triode, loudspeaker, power supply; One end of 3 one metal wires on 1 one metal wire that is provided with in the said wallet band and the said wallet front cover all is connected to the positive pole of power supply; The other end is respectively as the input of 2 NAND gates among the chip CD4011, with the output of said 2 NAND gates respectively through diode D1 and D2 short circuit; In addition 2 NAND gates of CD4011 are connected into the monostable device that sets out; The short circuit of D1, D2 is exported the input signal of signal as said monostable flipflop; The output signal of monostable flipflop is connect the base stage of triode Q1 through resistance R 4, loudspeaker is jumped between the colelctor electrode and emitting stage of triode Q1.
The utility model advantage is: the user through the metal hanger on the wallet band with wallet not on the waist of trousers, in case the thief cuts off the wallet band in the process of committing theft or the wallet front cover is scratched, loudspeaker then can send intermittent chimes of doom.

Fig. 2 is the circuit diagram of a kind of anti-scratch of the utility model, antitheft wallet.
Fig. 3 is CD4011 chip functions figure.
The specific embodiment
The utility model is further specified through the specific embodiment below in conjunction with accompanying drawing.
A kind of anti-scratch, antitheft wallet; Comprise wallet front cover and wallet inner bag, it also comprises a wallet band (1) in addition, and wallet band centre position is provided with a metal hanger (2); Be provided with 1 in wire in the said wallet band, on said wallet front cover, be provided with wire 3 (3), (4), (5).
In addition; This wallet also comprises chip CD4011, resistance, electric capacity, diode, triode, loudspeaker, power supply; One end of 3 one metal wires on 1 one metal wire that is provided with in the said wallet band and the said wallet front cover all is connected to the positive pole of power supply; The other end is respectively as the input of 2 NAND gates among the chip CD4011, i.e. CD4011 No. 1, No. 2 and No. 5, No. 6 pin; No. 3 pin of output of said 2 NAND gates, No. 4 pin are passed through diode D1 and D2 short circuit respectively; In addition 2 NAND gates of CD4011 are connected into the monostable device that sets out; The short circuit of D1, D2 is exported the input signal of signal as said monostable flipflop, promptly insert No. 13 pin of CD4011; With the output signal of monostable flipflop is No. 10 pin of CD4011 meet triode Q1 through resistance R 4 base stage; Loudspeaker is jumped between the colelctor electrode and emitting stage of triode Q1.The foregoing circuit part all is located in the wallet front cover (6).
The utility model main points are: the user through the metal hanger on the wallet band with wallet not on the waist of trousers; In case the thief cuts off the wallet band in the process of committing theft or the wallet front cover is scratched; Then wire in the wallet band or the wire in the wallet front cover will break off, and the input signal of the CD4011 NAND gate that is attached thereto then will become 0 signal, and its output signal becomes 1 signal; Make monostable flipflop work; Through the output signal amplification back promotion speaker operation of triode, finally make and play the warning effect by the intermittent sounding of loudspeaker monostable flipflop.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within the protection domain of the utility model.
