Abstract

The utility model discloses an acousto-optic caution device of a door lock comprising a latch bolt detection sensor, a cipher rotor detection sensor, a control circuit and a warning device. The latch bolt detection sensor used for detecting the state of the latch bolt is arranged at the latch bolt. The cipher rotor detection sensor used for detecting the state of the cipher slice is arranged at the cipher lock body. The control circuit receives the detection signal emitted by the sensor and indicates the warning device to emit the signal. The acousto-optic caution device of the utility model can detect the latch bolt and the cipher rotor simultaneously. The two detection signals are conveyed to a logic circuit and are judged if the door lock is really locked through the comparison. If the door lock isn't really locked, a drive circuit can drive a flash lamp and a buzzer to work. The acousto-optic caution device of a door lock plays the caution function for the operator and obtains the effect of the safe theft protection.

Description

The door lock acousto-optic warning device

Technical field

The utility model relates to a kind of alarming device, relates in particular to the alarming device that is used for lockset.

Background technology

Consider antitheft, security needs, the exploitation of door lock technology is maked rapid progress, the technological prevention measure of more having developed recognition systems such as various closed-circuit TV monitoring systems, guard against theft and alarm system, fingerprint, palm shape, pupil film simultaneously makes the anti-theft feature of door lock more become perfect.Be typically the antitheft of national treasury door the most, its lockset must be lock---a national treasury door special-purpose machinery coded lock the tightest, the most reliable, that insure most.Because this characteristic of national treasury door mechanical code lock, its operation is very loaded down with trivial details.Unblank, operation such as locking and coding must carry out in strict accordance with operational procedure, any little mistake all can cause operation failure.Simultaneously, after this lockset special feature was that its dead bolt stretches out, not necessarily expression was locked.Locking truly is not only dead bolt and will be stretched out fully, also wants the structure cipher chips in the lock body to be dialled disorderly simultaneously.Because dead bolt stretches out and pulls out random locking plate is not synchronously, so operating personnel accidentally just may cause the national treasury door lock really not locked.Like this, no matter the national treasury door has been equipped with how tight lockset, if do not lock, and the national treasury door that also is equal to nothing, the seriousness of its consequence is hardly imaginable.Therefore, be necessary to develop a kind of product, can warn lockset and be in unlocked state, to stop this type of error.

Summary of the invention

The purpose of this utility model is to provide a kind of device that can send caution sound and light warning lamp when lockset is unlocked.

The utility model is achieved through the following technical solutions the foregoing invention purpose: comprise lock body and alarming device, described alarming device can be installed in Anywhere, is made up of dead bolt detecting sensor, password rotor detecting sensor, national treasury door condition sensor, control circuit and acousto-optic attention device etc.;

The dead bolt detecting sensor is installed in dead bolt and is stretched out the place, is used to detect the state of dead bolt; Password rotor detecting sensor is installed in coded lock, is used to detect the state of cipher chips;

The detection signal that the control circuit receiving sensor sends, and the action of control attention device.

Acousto-optic warning device of the present utility model, can detect dead bolt and password rotor simultaneously, then these two detection signals are delivered in the logic circuit, really lock by relatively judging whether, as not being real locking, drive circuit just drives flash lamp and buzzer work, and the operator is served as warning, and reaches the safe antitheft effect.

Description of drawings

Fig. 1 is an electrical schematic diagram of the present utility model.

Fig. 2 is the utility model sensor scheme of installation.

The specific embodiment

As shown in Figure 1, acousto-optic warning device of the present utility model comprises dead bolt sensor 1, password sensor 2, national treasury door condition sensor 3, logic circuit 4, drive circuit 5, power circuit 6, stand-by circuit 7, flash lamp 8 and buzzer 9.As shown in Figure 2, dead bolt sensor 1 is installed on dead bolt, is used to detect the state of dead bolt.Password sensor 2 is installed on coded lock, is used to detect the state of cipher chips.National treasury door condition sensor 3 is installed on the doorframe, is used for detecting gate body open and-shut mode.

Dead bolt sensor 1 and password sensor 2 detect the dead bolt of door lock and the state of lock body inner structure cipher chips, and detected signal is passed to logic circuit 4.Logic circuit 4 learn after by analysis door lock really do not lock (be that dead bolt does not stretch out fully or dead bolt stretches out fully, cipher chips is dialled disorderly) then can send signal and give drive circuit 5, by drive circuit 5 luminous the or buzzer of flash lamp 8 is rung.

After the lockset unlatching, the national treasury door is opened for a long time, buzzer 9 is worked long hours send " toot " " toot " sound interference working environment, national treasury door state detection sensor 1 is after the national treasury door is opened, transmit signal to logic circuit 4, force buzzer 9 to quit work, but flash lamp 8 also work on; When the door leaf of national treasury door cover fully close on the doorframe after, national treasury door state detection sensor 1 sends signal again, and buzzer 9 is resumed work, and sends " toot " " toot " sound again, the prompting locking.
