CN2133182Y - Anti-stealing wallet with cipher switch group - Google Patents

Abstract

The utility model comprises a cipher switch, a music integrated block, a buzzer, a current-limiting resistor, two magnets, and a power switch, wherein, the cipher switch comprises four key-typed single-pole double-throw switches which are connected in series; the power switch also is a key-typed single-pole double-throw switch; the two magnets are respectively arranged at the bottom of the wallet and the bottom of a pocket. When the wallet falls from the pocket, the buzzer gives an alarm; when the wallet is put in and taken out, the four cipher switch keys are arranged on the presetting corresponding ciphers to make the buzzer in a closing position so the alarm of the buzzer can be avoided.

Description

Anti-stealing wallet with cipher switch group

The utility model relates to a kind of antitheft wallet.

Along with rapid economic development, the chance that people go out is more and more, and wallet phenomenon stolen or that lose also will get more and more, therefore, and the antitheft big problem that becomes people's care of wallet.

" electronics newspaper " once reported and a kind ofly triggered the antitheft wallet that the news Chinese percussion instrument is reported to the police with photosensor signal, and its defective is that one if clothes is thinner, easily produces misoperation when being subjected to strong illumination; Its two, powered-down at first when the user takes out wallet, otherwise can misoperation.If power switch is easy to, then the thief also is easy to go smoothly, if switch designs becomes to be difficult for switch, then the user uses just very inconvenient; Its three, wallet is stolen or do not lose and can report to the police at night.

For fear of the deficiency that above-mentioned antitheft wallet exists, to be that design is a kind of forms the antitheft wallet of cipher switch by mechanical switch to the purpose of this utility model, needs only wallet and is taken out pocket by other people, then interrogates Chinese percussion instrument and reports to the police immediately.

The utility model reaches purpose of design by following concrete structure: the cipher switch that it is made up of one group of button single-pole double-throw switch (SPDT), music-integrating block, news Chinese percussion instrument, current-limiting resistance, button single-pole double throw power switch, magnet and dc source constitute, dc power anode connects cipher switch by current-limiting resistance, negative pole connects cipher switch by power switch, the output of cipher switch links to each other with the trigger end of music-integrating block, the news Chinese percussion instrument is connected between music-integrating block and the positive source, and magnet is individually fixed in wallet and pocket bottom.When putting into and take out wallet, only will be installed on single-pole double-throw switch (SPDT) on the wallet when making its state that all is in the pass by the password that presets with correct pin mode, could guarantee that the news Chinese percussion instrument do not report to the police, thereby guarantee that wallet can be not stolen or lose.

Further specify the utility model below in conjunction with accompanying drawing.

Fig. 2 wallet bottom and pocket interaction schematic diagram.

The cipher switch that Fig. 3 button single-pole double-throw switch (SPDT) is formed

The mounting means of button single-pole double throw power switch K as shown in Figure 2.Magnet M sews up the pocket bottom, when packing wallet into pocket, when the magnet F of pocket internal magnet and wallet bottom is pulled together mutually the button of K is pressed, and wallet is put well.Do the time spent when wallet is subjected to external force, two blocks of magnet separate, and the moment that key switch K upsprings automatically produces a trigger current, triggers music integrated block IC, and the news Chinese percussion instrument is reported to the police.

Cipher switch U is made up of four button single-pole double-throw switch (SPDT)s, and two fixed points of each switch represent 0 and 1 respectively, and thus, this cipher switch has 16 kinds of compound modes of tetrad representative.On a wallet, only preset a password.When putting into and take out wallet, the news Chinese percussion instrument is not reported to the police, simultaneously, wallet is after putting pocket into, anyone must press cipher switch with the coding that presets, take out wallet, the news Chinese percussion instrument just can not reported to the police, thereby reaches the purpose of antitheft anti-mistake.

The utility model is simple in structure, material requested is few, and it is little to account for volume, except that news Chinese percussion instrument and music-integrating block; all adopt the button single-pole double-throw switch (SPDT), dc source adopts button cell, produces easily; with low cost, will be to protection people property, the stable society order plays good effect.

Claims (2)

1, the antitheft wallet of forming cipher switch by switches set, it is characterized in that antitheft wallet is by cipher switch, music-integrating block, news Chinese percussion instrument, current-limiting resistance, button single-pole double throw power switch, magnet and dc source constitute, cipher switch is formed in parallel by four button single-pole double-throw switch (SPDT)s, its output links to each other with the music-integrating block trigger end, the news Chinese percussion instrument is connected between power supply and the music-integrating block, positive source connects cipher switch by current-limiting resistance, negative pole connects cipher switch by power switch, and magnet is individually fixed in wallet and pocket bottom.

2, as claimed in claim 1ly form the antitheft wallet of cipher switch, it is characterized in that the magnet that is fixed in wallet and pocket bottom can adopt an iron plate and a magnet by switches set.
