Below in conjunction with accompanying drawing the utility model embodiment is further described:
Fig. 1,3,4,5 and 6 forms the utility model first embodiment.Shown in Fig. 1,3,4,5,4 places that are installed in a front lock nut 1 have keyhole, the outer contact 6 that password indicator lamp 5, connection additional power source are housed and the keyboard 3 that the button 7 of figure notation is arranged placed of lock nut, the present embodiment keyboard is that annular keyboard is equipped with the lock nut circle 2 that fuses with them between lock nut and keyboard.The lock main body that is installed in a back side is made up of lock cap and the lock housing 14 that cage knob 8 is housed, 14 li of lock housings short dead bolt 10 is installed, the post 13 of unblanking, long dead bolt 29, long bolt plate 11, sliding shoe 30 and reference column 15, keeper 31 is installed on the doorframe corresponding with locking body position 20, and available door chain 12 is connected between lock main body and the keeper.Lock housing borough chief's bolt plate below is fastened with the cryptochannel 19 that comprises the relay 28 of being with armature 27, warning circuit 18, emergency circuit 21, the main circuit board 16 of socket 23 and hook switch 17, near the below of the band armature relay of long bolt plate block 25 on the lock housing of being fastened on is arranged, on the lock housing wall of main circuit board one end and dead bolt homonymy tongue tube 24 is housed, battery pack 22 and loudspeaker 26 are equipped with in the below of main circuit board in addition, on the position corresponding with tongue tube magnet 32 is housed on the doorframe, keyboard passes through plug, socket on the main circuit board connects with cryptochannel and emergency circuit.
The connection of the quantity sum counter by the password contact pin on the plug that change to connect keyboard can change the figure place of password, can change the password numbering by changing the order that connects the cryptographic key contact pin on the plug, be provided with pseudo-decoding circuit in the cryptochannel, blocking time can be determined by the selection to relevant condenser capacity with delay time.The magnitude of voltage of the additional power source of emergency circuit can be selected according to the operating voltage of cryptochannel repeat circuit and the resistance value of connecting with it, three's relational expression is that ∨ adds=IR+ ∨ work, can select the free voltage value for use, for safety, can be selected between 6 volts to 36 volts.
Cryptochannel is by the MOS integrated circuit U that is fixed on the main circuit board
1And U
2, relay J, 7 diodes, 1 triode, 8 resistance, 6 electric capacity and Voltaic battery group form, and works as C
3=4.7 μ and C
7Blocking time is 5 seconds during=4.7 μ, and delay time is 12 seconds.Warning circuit is by integrated circuit U
3, amplifier U
4, an electric capacity, resistance, loudspeaker and a Voltaic battery group forms.Emergency circuit is that 300 ohm the resistance and the band armature relay of cryptochannel are in series by a diode 1N4001, a resistance, and in parallel with additional power source by the contact on the keyboard during use, the magnitude of voltage of additional power source is 12 volts.
Along with the rotation of outdoor key or indoor cage knob, sliding shoe moves backward, and when reference column moved to the detent of close long dead bolt on the long bolt plate, long dead bolt was all return in the lock housing, will lack dead bolt again and dial back in the lock housing, and at this moment, lock is in the standard-sized sheet duty.Because short dead bolt has the trend of stretching out all the time under its spring action, then short dead bolt places in the keeper on the door knob, finishes general latch function.Run into behind the door, along with the rotation of key or cage knob, sliding shoe moves down, and when reference column placed on the long bolt plate interfix groove, half stretched out long dead bolt lock housing and enter keeper, realizes two tongues insurances.The outdoor use key rotates a circle again, bolt plate continues to move forward, move to reference column when placing last detent on the long bolt plate along being fixed on the inclined-plane of the armature of relay on the main circuit board, along with lifting of sliding shoe, armature rebounds and just in time pins sliding shoe, and under the acting in conjunction that places the block that is fastened on below the armature on the lock housing and armature, sliding shoe can't move, at this moment lock is in band Cipher safety duty, indoor can't unblanking.During outdoor unblanking, by to password, cryptochannel is connected earlier, at this moment the bright armature of relay of password indicator lamp is held, its position moves down abdicates the passage that sliding shoe moves down, allow sliding shoe under the rotary action of key, to move down, reference column is shifted out from growing in last detent on the bolt plate, remove the Cipher safety state, indoor, when the lock that will be in two tongues insurance duties with cage knob turns to the position that can not rotate again, door lock is lived outdoor can't unblanking from indoor.
Under the normal condition, door is shut, then tongue tube disconnects, and can not report to the police, when dead bolt is return the lock housing inside door and opened, hook switch disconnects, also can not report to the police, have only when dead bolt places the keeper inside door to be opened by violence, hook switch and tongue tube are just connected simultaneously, at this moment warning circuit power supply, loudspeaker sends chimes of doom.The loudspeaker parallel connection of a plurality of electronic cipher alarming locks just can realize how tame joint defence.
Fig. 2,3,4,5 and 6 forms the utility model second embodiment, its circuit and each component locations, function are basic with first embodiment, and difference is a rectangle at keyboard just, is fastened on the below of lock nut, the contact that scoops out the urgent telegram road only is housed on the keyboard, and does not adorn the password indicator lamp.
