Abstract
The utility model relates to a small anti-theft strong box, which is composed of a box body with a mechanical type code lock head and an alarm circuit. The utility model is characterized in that the alarm circuit comprises unlocking alarm and swinging alarm; the unlocking alarm uses electricity conducting spring sheets which are fixedly connected to a core shaft of the code lock head and an alarm switch which is composed of an electricity conducting plate arranged on the core shaft of the code lock head corresponding to the electricity conducting spring sheets as an alarm detector; the swinging alarm uses a swinging sensor which is arranged in the box body as the alarm detector; a power supply plate which is connected with a power supply and an earth plate are arranged in an interval mode by the electricity conducting plate along the circumference of which the position is provided with contacts of the electricity conducting spring sheets. The utility model has the advantages of small volume, light weight, and reliable safety function.
Description
The utility model relates to safeties.More particularly, be a kind of small-sized thief-resistant safe that is particularly suitable for family expenses.
Thief-resistant safe of the prior art is of a great variety, structure is different, the realization of its main insurance function, and the one, rely on trick lock, another is by the volume that increases casing and strengthens weight, so that stealer can't carry it.But the frame mode of trick lock is not reliable, as long as stealer has time enough, and rotational password at random, the possibility of unlatching is very big.Large volume and big weight make strongbox be restricted in the use of average family especially.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provides a kind of small-sized thief-resistant safe, so that strongbox enters family.
The purpose of this utility model is achieved through the following technical solutions.
The utility model is made of casing that has the mechanical code tapered end and warning circuit.
Design feature of the present utility model is:
A, described warning circuit comprise unblanks to report to the police and rock warning, and it unblanks to report to the police being that to be fixedly connected on the alarm switch that conductive reed on the trick lock mandrel and the corresponding conductive plate that is provided with constitute be alarm detector; Describedly rock that to report to the police be that rolling dynamic sensor to be arranged in the casing is an alarm detector;
B, described conductive plate at it along on the circumference of position, conductive reed contact, the power panel and the earth plate that are intervally arranged and are connected with power supply;
Compared with the prior art, the utlity model has following advantage:
1, the utility model setting rock warning circuit, can prevent effectively stealer to the carrying of strongbox, carry, thereby can reduce greatly on the volume He on the weight, use to be fit to family.
2, unblank in the utility model setting of warning circuit has greatly increased the safety reliability of strongbox.
Accompanying drawing is the utility model circuit theory diagrams.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, the utility model is made of casing that has the mechanical code tapered end and warning circuit.
Wherein, warning circuit comprises unblanks to report to the police and rock warning, and it unblanks to report to the police being that to be fixedly connected on the alarm switch that conductive reed H on the trick lock mandrel and the corresponding conductive plate B that is provided with constitute be alarm detector.Rocking reports to the police is to be alarm detector with the rolling dynamic sensor K2 that is arranged in the casing.
As shown in the figure, conductive plate B at it along on the circumference of position, conductive reed contact, the power panel and the earth plate that are intervally arranged and are connected with power supply.
In the present embodiment, between casing and casing door leaf, the push button K switch 1 of closing the door is set, button switch K 1 series connection is arranged in the warning circuit electric power loop.
Warning circuit adopts SCR control element and voltage comparison signal processor as shown in the figure, and the delay circuit that is made of resistance R 2, potentiometer W1 and capacitor C is set.Conductive reed H is connected the control end of controllable silicon SCR 3, and Shaking switch K2 is arranged on the control end of controllable silicon SCR 2.
In the present embodiment, adopt four voltage comparator ics 1, in order to improve functional reliability, the voltage comparison signal processor is by two comparator B1, the B2 use that is connected in parallel.All the other both comparator B8, B4 are connected in parallel with external connection, can do with standby.
This device can directly be embedded in body of wall, or is fixed on the wall.
When normal pass behind the door, K switch 1 is connected, the warning circuit power connection, at this moment, because the contact of conductive reed H contacts with the earth plate 2 of conductive plate B, the switch of its formation is for leaving state, controllable silicon SCR 3 is ended, controllable silicon SCR 1 thereby end, at this moment, do not rock signal owing to have, controllable silicon SCR 2 is also for ending.
As the rotation of trick lock mandrel, at this moment, because the contact of conductive reed H contacts with the power panel 1 of conductive plate B, the switch of its formation is an off status, and controllable silicon SCR 3 is because control end high level and triggering and conducting, immediately, controllable silicon SCR 1 conducting, capacitor C 1 begin charging.After of short duration time-delay, because the rising of capacitor C 1 terminal voltage, comparator B1, B2 export high level.At this moment, no matter have or not and rock signal, controllable silicon SCR 2 is all transferred conducting, and the phonation circuit that is made of alert sound ic chip 2, amplifying circuit BG2, BG8 and loudspeaker Y1 sends chimes of doom.
Take place as rocking signal, because rolling dynamic sensor K2 is switched on, no matter the tapered end mandrel rotates in not, because the conducting of controllable silicon SCR 2, loudspeaker Y2 sends warning equally.
For the strongbox owner, in the process of unblanking, the generation of warning triggering signal is arranged equally, still, unblank as long as in the delay time of regulation, finish, open the casing door leaf, because after opening the casing door leaf, K switch 1 is disconnected, the warning circuit power supply is cut off, comparator can not trigger upset, and circuit does not have alert sound.
