Description

Electronic cipher double protective safe

The utility model relates to a kind of burglar alarm safeties in the physical field, particularly is suitable for the fixedly safety cabinet of family expenses.

Existing burglar alarm safety cabinet mostly is portable, generally password key is directly installed on the cabinet door, and the cooperative mechanical lock uses together, as pushes the wrong password, then sends alarm sound, and the cabinet door is not opened.Chinese patent 90213089.7 " the comprehensive automatic antitheft radio alarming protector " that provided for example, adopt radio alarming emission, reception and self warning locking, has warning function preferably, but cost height, password can not be changed at any time, button is exposed to the outside, easily goes to pot, and influences integrated beauty.

The purpose of the utility model is to provide a kind of appearance smooth attractive in appearance, has dual-layer antitheft door, user and can change password, two anti-family expenses safety cabinets of electronic cipher that antitheft security performance is good at any time.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model circuit diagram.

Technical solution of the present utility model is: this electronic cipher double protective safe consists of by being embedded in fixed building fixed frame (1) and safety cabinet shell (2), protective door (3), password door (4), control flow (5), replacing cipher drawer (6) and control circuit within the walls. safety cabinet shell (2) is fixed on the fixed frame (1) by the cabinet inner bolt. Protective door (3) is external door, and password door (4) is inside door, and protective door (3) is locked on the control flow (5) by mechanical lock buckle. Password door (4) is by password key (7) and the control of the control circuit in the cabinet of control flow (5). Control circuit is installed in to be changed in cipher drawer (6) and the control flow (5). Control circuit includes decimal system arteries and veins Rush counter (8), trigger (9), drive circuit (V₂、J ₂), password key (7), insurance button (10), time power source follower (11), high-voltage pulse circuit (12), warning circuit (13) and dc source.

Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail:

As shown in Figure 1, the fixed frame (1) of the two anti-family expenses safety cabinets of this electronic cipher is embedded within the walls, the cabinet inwall of safety cabinet shell (2) has screw hole, by screw safety cabinet shell (2) is tightened and to be fixed on that fixed frame (1) is gone up, safety cabinet has two-layer door, external door is protective door (3), and inside door is password door (4).Protective door has keyhole on (3), and protective door (3) inboard has protective door snap close (14); Protective door snap close (14) can insert the protective door buttonhole (15) on the control flow (5).Protection door lock (16) also is installed on the control flow (5), and key is inserted protection door lock on control flow (5) from the protective door keyhole.Protective door lockset in the control flow (5) has double end rod bolt and snap close, in order to pinning protective door securely.Password door (4) then is locked on the password knocker eye (17) on the control flow (5) by electromagnetic lock.Electromagnetic lock is controlled by control circuit; Control circuit is installed in to be changed in password drawer (6) and the control flow (5).When protective door (3) when shutting, password door (4) and password key (7) all are locked in the inside, and the outside be cannot see and be can not touch.Also cut off simultaneously the control circuit power supply.Password key (7) is installed on the control flow (5), after opening protective door, just connect the control circuit power supply automatically with key, and reveal password door (4) and password key (7), but change password drawer (6) still in password door (4), the operator is as long as press password, and password door (4) just automatically springs open.If push the wrong password, electrical equipment automatic blocking, and send chimes of doom.Owner only wants to change password, need only draw back and change the password drawer, and changing, plug gets final product.Control circuit includes decadic pulsing counter (8), trigger (9), drive circuit (V ₂, J ₂), password key (7), insurance button (10), power supply regularly follower (11), high-voltage pulse circuit (12), warning circuit (13) and dc source etc.Decadic pulsing counter (8) adopts integrated circuit MC14017, and trigger (9) adopts integrated circuit MC140106, behind the connection power supply, because capacitor C ₃Last voltage can not suddenly change, and trigger (9) 2 pin output high level resets MC14017.C ₃After the charging, C ₃The upper end is a high level, trigger (9) 2 pin output low levels, and MC14017 is in count status.First knob K when password key (7) ₅During connection, trigger (9) 4 pin become high level, after shaping is anti-phase, be added on 14 pin of MC14017, and one of rolling counters forward, 3 pin high level of counter (8) move on on 2 pin.Second button K of password key (7) ₆During connection, MC14017 counts a number again, and 2 pin high level move on on 4 pin, and by parity of reasoning, and 3 pin high level move on to 6 pin always, through R ₃C ₄About charging time-delay 1 moved, trigger (9) was made driven in phase, is added to the triode V of drive circuit by 8 pin ₂Base stage on, V ₂Conducting, relay J ₂Closure, electromagnetic lock DT energising traction is unblanked.Gate circuit M ₁, M ₂, M ₃And triode V ₁Deng composition power supply timing follower (11), the K-K in safety button (10) ₅In any when connecting, V ₁Electric current about output 200mA makes relay J ₁Connect J ₁The contact is connected warning circuit (13) and is reported to the police, and the locking cryptochannel.Warning circuit (13) is by integrated circuit KD-5961 and triode V ₃, composition such as loudspeaker, report to the police and blocking time was designed to about 5 minutes.Dotted portion is high-voltage pulse circuit (12), J among Fig. 2 ₁High-voltage pulse circuit (12) power supply is also connected in the contact, can produce ten thousand volts of above voltages, use for the two anti-family expenses safety cabinets of portable electronic cipher, this voltage is non-life-threatening, but the thief can't contact, safety cabinet shell of the present utility model be provided with thicker isolation layer, in establish automatic cooling and extinguishing fluid, thereby have fire performance, therefore the utility model can make three kinds of forms: i.e. wall type, packaged type and fire prevention formula.

Advantage: this electronic cipher double protective safe appearance is smooth attractive in appearance, has dual-layer antitheft door, and the user can change password at any time, antitheft security performance is good, and use and maintenance is convenient, is a kind of suitable novel household Theft-proof cabinet new product.
