Abstract
The utility model relates to a dislocation and induction type theft-proof alarm device used for a suitcase during leaving which is a theft-proof alarm device arranged on the suitcase. The utility model adopts electromechanical leaving alarm and is controlled by a switch. The utility model can be set into a 'user holding' and a 'theft protection' states, wherein, the 'theft protection' state is ensured not to be destroyed by an induction triggering alarm circuit, and the utility model has warning function by touching. The utility model overcomes the defects of easy malfunction and damage existing in the existing theft-proof alarm device for a suitcase. The utility model has the advantages of high reliability, convenient operation, small size and low cost, and the utility model is suitable for multiple model suitcases.
Description
The utility model belongs to a kind of suitcase burglar alarm.
Present being seen suitcase burglar alarm great majority belong to the anti-type of alarm of plundering, only covert warnings of slipping out of the hand of its function, and must have an energy just anti-theft alarm function may be set with chain lock pinning suitcase and the object that is difficult for moving.It is that the vibration that utilizes suitcase to produce when mobile triggers the difference frequency device in the warning circuit and sends warning that minority burglar alarm suitcase is also arranged.Also have with mercoid switch and control warning.These suitcase burglar alarms are not only made and are installed difficulty, manipulate inconvenience, and main be malfunctioning easily and destroy, usually because the spring leaf fatiguability in the antitheft jack and can not reset or lost warning function because of the wiring of difference frequency device twists off.Mercoid switch then can not become inoperative because of original state.
The purpose of this utility model is intended to make reports to the police sensitivity reliably, and fabrication and installation are simple, and easy operating uses.
Above-mentioned purpose realizes by following technical measures.As shown in Figure 1, the utility model has adopted the reliable electromechanical warning circuit of offing normal.Wherein integrated package 555 is connected into bistable state (by the diagram connection), its output signal drives the siren generation circuit that integrated package PT328 constitutes, and is controlled the triggering of integrated package 555 by spring (1).Utilize the weight compression spring (1) of suitcase during use, the break trigger circuit, when suitcase slightly overhead, spring (1) resets immediately, connects circuits for triggering, alarm sends the police whistle sound with deterrent force immediately and reports to the police, and makes and can't steal suitcase.For avoiding suitcase when carrying, to cause warning because of collide or put to put temporarily, in circuit, designed a double-point double-throw switch K, this switch can be provided with " antitheft " and " carrying certainly " two states.
Under " carrying certainly " state, a cutter K of K switch
bCan disconnect the warning circuit of offing normal.And another cutter K of K switch
aThen with resistance R
1, capacitor C
1Constitute sensor trigger circuit, K
aConnection shown in accompanying drawing one.Suitably select C
1Parameter, can utilize C
1At K
aThe moment of pulling (being in the transient process of switch) the instantaneous potential change that discharges and recharges generation, trigger integrated package 555 and report to the police.Make thus behind power connection, as long as which side no matter an operating switch K(pull towards) just can respond to trigger and report to the police, after being provided with, to destroy " antitheft " state that guaranteed, solved the contradiction that electromechanical is offed normal and produced when warning device uses dexterously, but and when in danger also operating switch K manually send out the police, also adopt the metal edge frame (P on the suitcase in the design
1, P
2) constitute the touch mode alarm circuit, no matter under which kind of state, as long as touch P
1, P
2, can trigger warning, so just can when being plundered or be destroyed, suitcase report to the police automatically.Integrated package 555 once trigger stable state output, only after power supply disconnects, just can reset, stop the whistling of reporting to the police.Want first deenergization during use, connect power supply again after K switch is set.And power switch can be insured by mechanical lock.
A specific embodiment of the present utility model is shown in accompanying drawing one.Wherein, R
1-300～500K, C
1-0.1～10 μ, K-small capacity double double-pole double throw switch, BG1-3A * 81.Case lock dead bolt (2) is installed on the case lid, with casing upper side frame (P
1) riveted joint, lock body (3) is installed on the casing, with casing frame (P
1, P
2) insulation, by case lock double as power switch.Upper and lower frame (the P of casing
1, P
2) be metal material and mutual insulating and be contained in outside the casing.Spring (1) is installed in certain case pin and can contacts with ground.K switch is installed near the handle of casing outside.Remaining part all seals and places in the casing.
The characteristics such as the utility model uses proof through reality, and it is reliable, multiple functional, simple to operate to have a sensitive alarm, easy to use.
The utility model manufacturing is simple, and (about 10 yuan) with low cost, volume is small and exquisite, can adaptive Multiple Type and the suitcase of style.
Claims (3)
1, a kind of suitcase burglar alarm that has siren generation circuit is characterized in that:
(a) adopt integrated package 555 to be connected into bistable state, promptly 4,8 pin connect positive source, 1 pin connects power cathode, and 6 pin make it and positive source is connected (disconnections) as trigger end and by reset (compression) of spring (1), and forming offs normal triggers after 8,3 pin output driving siren generation circuit;
(b) resistance R
1An end and positive source join a cutter Ka and the series capacitance C of another termination double-point double-throw switch K
1, C
1The other end and the trigger end 6 of integrated package 555 join, two of Ka throw the position all joins with power cathode, another cutter Kb of K then controls the break-make of the circuits for triggering of offing normal;
(c) trigger end 6 of positive source and integrated package 555 respectively with the metal frame (P of two mutual insulatings
1, P
2) link;
(d) the double power switch of doing of case lock.
2, according to the described alarm of claim 1, it is characterized in that metal frame P
1, P
2Be respectively the upper and lower frame of suitcase.
3, according to the described alarm of claim 1, it is characterized in that resistance R
1Be 300～500K, capacitor C
1Be 0.1～10 μ.
