Abstract

The utility model discloses a thick type antitheft wallet, which can be used by matching with travelling suitcases or bags. The thick type antitheft wallet comprises an upper cover and a money box with a turnoff alarm circuit. A turnoff alarm is a turnoff oscillating circuit which comprises a battery, a toggle switch, a dynatron with small power, a piezoelectric ceramics piece which is provided with a feedback electrode, and a sensor. The piezoelectric ceramics piece is covered with a sound production cavity in which a sound production hole is arranged so as to make a louder alarm sound. The thick type antitheft wallet has the advantages of simple structure, low cost, etc.

Description

Thick type anti-thief purse

The utility model relate to a kind of antitheft wallet that has electronic alarm particularly can be placed on make it in satchel or the suitcase also can be antitheft thick type wallet.

A kind of duricrust suitcase burglar alarm is disclosed in CN85204553.It is that circuit such as logic circuit and power amplifier are formed by power supply, key switch, vibration triggering, broken string triggering, multi-harmonic-oscillations, and its weak point is complex structure, cost height and can only be applicable to hard shell trunk etc.

The purpose of this utility model be for avoid that above-mentioned weak point of the prior art provides a kind of simple in structure, cost is low, can and suitcase or wrap the antitheft wallet of matching used thick type.

The purpose of this utility model is to reach by following measure.

The antitheft wallet of thick type is made up of the money box of a loam cake and a band breaking alarming circuit, its breaking alarming electric routing battery, toggle switch, low-power transistor and sounding component and sensor composition with piezoelectric ceramic piece formation of feedback electrode, wherein sensor is that sensor series connection forms and links to each other with emitter stage with transistor base by the sensor of uncapping with taking off, and taking off is that sensor has the core flexible circuit conductor being arranged and constituting with the jack that the sensor of uncapping links to each other with transistor emitter respectively with two of plug by two ends.Connect with hinge between loam cake and the money box.

Below in conjunction with description of drawings embodiment of the present utility model:

Fig. 1 is circuit theory diagrams of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 often opens the press-button structure schematic diagram;

Fig. 4 is piezoelectric ceramic piece supporting construction figure;

Fig. 5 Fig. 6 is the utility model use figure;

1 flexible circuit conductor among the figure, 2 piezoelectric ceramic pieces, 3 line traps, 4 jacks, 5 magnet, 6 tongue tubes, 7 toggle switches, 8 layer-built batteries, 9 sensors, 10 plate buttons, 11 loam cakes, 12 hinges, 13 vocal holes, 14 money boxs, 15 dividing plates, 16 check rooms, 17 springs, 18 buttons, 19 moving contacts, 20 static contacts, 21 ends, sat, 22 packing rings, 23 nuts, 24 screws, 25 base plates, 26 sounding chambeies, 27 vocal holes, 28 plate buttons, 29 suitcases, 30 antitheft wallets, 31 handles, 32 metal connecting sheets, 33 luggage carrier battens, 34 satchels, 35 braces NULLs 36.

As shown in Figure 1 and Figure 2, the utility model is with the money box 14 of breaking alarming circuit to be connected through the hinge by a loam cake 11 and and is formed, warning circuit is one by layer-built battery 8, and toggle switch 7, the piezoelectric ceramic piece 2 with feedback electrode, triode (BG) sensor 9 and three resistance are formed oscillating circuits; Sensor two ends are connected on respectively on the base stage and emitter stage of triode, when sensor conducts, the base stage of triode and emitter stage are equipotentials, oscillating circuit is in the failure of oscillation state, the base stage of triode and emitter stage are disconnected when sensor disconnects, two electrode potentials do not wait, circuit oscillation, and piezoelectric ceramic piece 2 sends alarm sound immediately; Sensor 9 is by a uncap sensor and to take off be that sensor series connection forms, the sensor of uncapping can be made up of a magnet in the loam cake 5 and a tongue tube 6, the tongue tube two ends are respectively with transistor base with to take off be that the jack 4 of sensor links, the position of magnet 5 is corresponding with the position of tongue tube, NULL 36 is arranged between magnet and the loam cake, on cover the vocal hole corresponding 27 with the piezoelectric ceramic piece position, taking off is that sensor is the plastics flexible circuit conductor 1 of plug 3 to be arranged and the jack 4 that links with tongue tube 6 and transistor emitter respectively constitutes in the braces 35 that the plastics flexible circuit conductor can be manufactured on traveling bag (as shown in Figure 6) by two ends.

The antitheft wallet of this thick type can be used with suitcase or satchel, as Fig. 5, shown in Figure 6, during use flexible plastic lead 2 is tied up on the metal connecting sheet 32 of suitcase or on the satchel, plug 3 is inserted jack 4, toggle switch 7 closes, lock antitheft wallet, because of the flexible plastic lead with by the effect of magnet adhesive tongue tube, make to be switched between the base stage of triode and the emitter stage and become equipotential, oscillating circuit is in the failure of oscillation state, when stealer is stolen case or bag or sever, when prying open case or bag and stealing the wallet of the inside or when prying open wallet and stealing money, must can make plug 3 disengaging jacks 4, or different disconnected flexible plastic lead, or make magnet 5 leave tongue tube 6, the base stage and the sensor between the emitter stage of triode are disconnected, circuit oscillation, piezoelectric ceramic piece will send alarm signal immediately.

The tongue tube sensor can replace by often opening button sensor as shown in Figure 3, often open button sensor by spring 17, sit 21 and constitute at button 18, moving contact 19 static contacts 20, the end, and two static contacts are that sensor jack 4 links with transistor base with taking off respectively.

As shown in Figure 4, for making the alarm sound that sends bigger, so that the user can hear that alarm signal can be supported on the piezoelectric ceramic piece with feedback electrode on the base plate 25 with screw 24, packing ring 22 nuts 23 when this wallet and suitcase or bag were used, the strong point is the nodal point of this piezoelectric ceramic piece 2, base plate 25 is placed in the sounding chamber 26, and there is a vocal hole 27 position over against piezoelectric ceramic piece on the sounding chamber.

That the utility model compared with prior art has is simple in structure, widely applicable, can with the advantages such as suitcase or bag are used.
