Description

Electronic cipher anti-theft alarm door backup circuit breaker

The utility model relates to a kind of electronic cipher anti-theft alarm door backup circuit breaker, particularly a kind of electronic cipher anti-theft alarm door mechanical cipher warning backup circuit breaker.

Chinese patent CN99215170.8 discloses a kind of " electronic cipher anti-theft alarm door ", it cooperates with electronic code device and mechanical key lock controls unlatching, and wrong by password, destroy the door body or door lock assembly not only can not be opened door and report to the police immediately, this door had both been accomplished firm insurance, become again that passive passiveness is antitheft to be aggressive warning, but not enough is, in case power supply, single-chip microcomputer, circuit break down, the owner in the house door of not opening, manufacturer also is difficult to open door, has both made please " company of unblanking " or inventor of no avail.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of mechanical cipher warning backup circuit breaker of electronic cipher anti-theft alarm door is provided, in case the power supply of electronic cipher anti-theft alarm door, single-chip microcomputer, circuit break down, the crypto-alarm switch of can operating machine, in alarm sound, revolve to password again toggle switch can open the door.

The purpose of this utility model can realize by such technical scheme: this electronic cipher anti-theft alarm door backup circuit breaker, it comprises that mechanical code lock, mechanical code lock in the electronic cipher box that is provided with in the body is long-armed, microswitch, movable abaculus, installing plate, guide groove, connecting rod, pin thick stick connecting ring, warning circuit, loudspeaker, power supply, it is long-armed that lock core termination one side of mechanical code lock is provided with mechanical code lock, and link to each other with microswitch; Described movable abaculus is provided with inside and outside retaining, by inside and outside retaining movable abaculus is fixed on the guide groove that installing plate is provided with, and movable abaculus one end connects mutually with mechanical code lock rotating disk square groove, and the other end links to each other with connecting rod, and connecting rod links to each other with pin thick stick connecting ring; Described microswitch one termination power positive pole, the other end passes through resistance R ₁G links to each other with the controllable silicon SCR control utmost point, and passes through resistance R ₁, resistance R ₂Link to each other with power cathode, positive source links to each other with the controllable silicon SCR anode A, and controllable silicon SCR anode K links to each other with warning circuit, loudspeaker, power cathode.

Electronic cipher anti-theft alarm door backup circuit breaker provided by the utility model, an exportable high level signal is to the watch room between its warning circuit and controllable silicon SCR negative electrode K.

This electronic cipher anti-theft alarm door backup circuit breaker provided by the utility model makes the electronic cipher anti-theft alarm door practical more, and especially it has overcome many drawbacks of being brought because of electronic cipher anti-theft alarm door apparatus failure, and simple in structure, and cost is low.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:

This electronic cipher anti-theft alarm door backup circuit breaker structural representation that Fig. 1 is provided for the utility model embodiment;

Fig. 2 is a circuit diagram shown in Figure 1.

As shown in Figure 1 and Figure 2, this electronic cipher anti-theft alarm door backup circuit breaker that the utility model embodiment is provided, it comprises long-armed 2, the microswitch K of mechanical code lock 1, mechanical code lock in the electronic cipher lock box that is provided with in the body ₁, movable abaculus 3, installing plate 4, guide groove 5, connecting rod 6, pin thick stick connecting ring 7, warning circuit 8, loudspeaker 9, power supply, it is long-armed 2 that lock core termination one side of mechanical code lock 1 is provided with the machine coded lock, and with microswitch K ₁Link to each other; Described movable abaculus 3 is provided with outer retaining 10, interior retaining 11, makes movable abaculus 3 be fixed on the guide groove 5 that installing plate 4 is provided with movable abaculus 3 one ends and mechanical code lock by outer retaining 10, interior retaining 11

1 rotating disk square groove connects mutually, and the other end links to each other with connecting rod 6, and connecting rod 6 links to each other with pin thick stick connecting ring 7; Described microswitch k ₁One termination power positive pole, the other end passes through resistance R ₁G links to each other with the controllable silicon SCR control utmost point, and passes through resistance R ₁, resistance R ₂Join with power cathode, positive source links to each other with the controllable silicon SCR anode A, and controllable silicon SCR negative electrode K links to each other with warning circuit 8, loudspeaker 9, power cathode; An exportable high level signal 12 is to the watch room between warning circuit 8 and controllable silicon negative electrode K.

When the utility model uses, this electronic cipher anti-theft alarm door backup circuit breaker, long-armed 2 ends on its mechanical cipher lock shaft core tightly suppress microswitch K ₁, long close point is disconnected can not connect power supply, when the circuit of electronic cipher anti-theft alarm door broke down, mechanical cipher warning backup circuit breaker had just been sent use, and then rotated the microswitch K that was tightly suppressed originally as long as the handle rotation just drives long-armed 2 on the lock core ₁Closure out of hand, power supply is switched on, and one the tunnel send electricity through controllable silicon SCR anode A length, and another road is through microswitch K ₁, resistance R ₁Send electricity for control utmost point G, make the controllable silicon SCR conducting, from anode A to negative electrode K, warning circuit 8, loudspeaker 9 to negative pole have electric current to flow through warning circuit 8, loudspeaker 9 sends alarm sound, while high level signal 12 is reported to the police to the watch room.3 square grooves in chimes of doom on the rotating disk of continuation rotating machinery coded lock handle aligning coded lock are alignment activity abaculus 3 just, pull movable abaculus 3 and just embed in the square groove of mechanical code lock this moment, drive connecting rod 6 simultaneously, pin thick stick connecting ring 7 moves, the door bolt thick stick also and then moves, and the electronic cipher anti-theft alarm door is opened.
