Abstract

The utility model discloses an anti-theft and robbing-proof cipher case which is provided with an alarm device, wherein, the alarm device is arranged at the front side in a case cover of the cipher case. The alarm device comprises a power supply, an electronic switch, a sound production integrated block, duplex toggle switches K1, k2, a triode BG and a loudspeaker, the triggered end of the electronic switch is connected with the toggle switch k1, and the input end of the sound production integrated block is connected with the output end of the electronic switch. The front side of the case cover of the cipher case is provided with a socket and is matched with a fuze of which the both ends are respectively provided with attachment plugs, and meanwhile, a mercury switch is also arranged on the front side of the case cover. The fuze can be tied on a wrist, and can also be used as a chain lock. The utility model has the advantage of safe alarm, and effectively has the robbing-proof and anti-theft function.

Description

Anti-theft and robbing-proof cipher case

The utility model relates to a kind of antitheft, robbery prevention password case, is the improvement to the existing password case.

Combination lock is deposited valuables usually, and people carry when going out, and often becomes object stolen, that robbed.Therefore, relevant antitheft, anti-snatch alarm goes out 88220729 thereupon.No. 6 patent disclosures a kind of antitheft, collision horizontal tilt alarm, be provided with warning device and sensor, sensor is made of sensor shell and conduction ball, when collision or inclination, can send warning, but the sensor of this structure uses easily loose contact long afterwards, or not during this warning, when carrying, if movement range is excessive, false alarm ， And also can occurs and not have robbery-proof device.

The purpose of this utility model is to overcome above-mentioned defective, provide a kind of reasonable in design, can effectively play antitheft, anti-snatch combination lock.

The utility model is provided with warning device, and it comprises power supply E, electronic switch, sounding integrated package, duplex toggle switch K ₁, K ₂, triode BG, loudspeaker, the triggering termination toggle switch K of electronic switch ₁, the output terminal of sounding integrated package input termination electronic switch.The output terminal of the base stage sending and receiving sound integrated package of triode BG, collector meets toggle switch K through loudspeaker ₁, warning device is installed in front side in the combination lock case lid, and the case lid front side is provided with socket, and socket one utmost point is through resistance R ₄Meet power supply E Fu Ji And as toggle switch K ₂Contact, another utmost point meet toggle switch K ₁, K ₂Through resistance R ₃Receive the trigger end of electronic switch, socket sets the fuze with two plugs.

Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Accompanying drawing is the warning device line assumption diagram of present embodiment.

The warning device of present embodiment is installed in front side in the combination lock case lid, and warning device comprises power supply E, electronic switch (2), sounding integrated package (7), duplex toggle switch K ₁, K ₂, triode BG, loudspeaker (8), the trigger end (9) of electronic switch (2) is through resistance R ₁Meet toggle switch K ₁, working power end (10) meets toggle switch K ₁, output terminal (11) is through capacitor C ₁Connect power supply E negative pole, sounding integrated package (7) input end (12) connects the output terminal (11) of electronic switch, and output terminal (9), the collector of the base stage sending and receiving of triode BG, sound integrated package meet toggle switch K through loudspeaker (8) ₁, emitter-base bandgap grading connects power supply E negative pole.The case lid front side is provided with socket (1), and socket (1) one utmost point is through resistance R ₄Meet power supply E And as toggle switch K ₂Contact, another utmost point meet toggle switch K ₁, toggle switch K ₂Through resistance R ₃Receive the trigger end (3) of electronic switch (2).Socket (1) sets the fuze (4) that two has plug.Present embodiment also is provided with mercury cut-off.Mercury cut-off is made of glass bulb (5) and mercury bead (6).One utmost point connects power supply E negative pole, another utmost point as toggle switch K ₂The contact.

As toggle switch K ₂Beat when socket (1) contact toggle switch K ₁Energized E, electronic switch (2) obtains working power, because resistance R ₄Higher, the resistance R of resistance ₃Resistance lower, at R ₄A higher pressure drop is obtained at two ends, and therefore, the trigger end (9) of electronic switch (2) obtains a positive feedback voltage, and hoop makes it not work toward electronic switch (2).In case the fuze (4) on the socket (1) is transferred to or is disconnected, then above-mentioned positive feedback voltage forfeiture, the trigger end (9) of electronic switch (2) obtains a normal signal voltage, electronic switch (2) work, drive sounding integrated package (7), make triode BG conducting, loudspeaker (8) is reported to the police.

As toggle switch K ₂Beat when the mercury cut-off contact toggle switch K ₁Energized E, because trigger end (3) the no signal voltage of electronic switch (2), electronic switch (2) is not worked, in case combination lock shakes, mercury bead in the mercury cut-off (6) is connected two electrodes at once, makes trigger end (9) obtain a normal signal voltage, electronic switch (2) work, through sounding integrated package (7), triode BG, loudspeaker (8) is reported to the police.

Above-mentioned two kinds of warnings are only cut off the electricity supply, and are about to toggle switch K ₁, K ₂Dial and to eliminate to neutral gear.When going out, fuze can be fastened on wrist, also can make chain lock usefulness, play anti-snatch, burglar alarm effectively; The mercury bead of mercury cut-off and two electrode contact performancies are good, and when the stolen generation of combination lock was rocked, it was safe and reliable to report to the police.

Claims

1, a kind of antitheft, robbery prevention password case that has warning device, warning device comprises power supply E, electronic switch, sounding integrated package, duplex toggle switch K ₁, K ₂, triode BG, loudspeaker, the triggering termination toggle switch K of electronic switch ₁, the output terminal of sounding integrated package input termination electronic switch, output terminal, the collector of the base stage sending and receiving sound integrated package of triode BG meet toggle switch K through loudspeaker ₁, of the present utility model being characterised in that: warning device is installed in front side in the combination lock case lid; The case lid front side is provided with socket (1), and socket (1) one utmost point is through resistance R ₄Meet power supply E negative pole ， And as toggle switch K ₂Contact, another utmost point meet toggle switch K ₁, toggle switch K ₂Through resistance R ₃Receive the trigger end (3) of electronic switch (2), socket (1) sets the fuze (4) that two ends all have plug.
