Inject in lock core 5 processes at key, at first the first tooth section of key touches the 5th row's hoodle, then the first tooth section of key touches the 4th row's hoodle, until after key all injected lock core, can touch the first row hoodle, this time, upper hoodle was in lock body, lower pellet just forms upper lower pellet defiber in lock core, just can open lock by rotating key this moment, as Fig. 1, above narration is exactly the basic principle that common lock is unblanked.In the utility model, as Fig. 2, the output Y130 of five hoodles, the one direct sum U2 on the left of lock is connected, current potential is all 1, injects in the process of lock core at key, and the conductive segment of key serves as the electric conductor effect, make the hoodle conduction on right side, insulating segment can not serve as the electric conductor effect.The upper lower pellet on right side forms reliable the electrical connection with the base stage of triode, purpose is to inject in the core process of lock at key, on five hoodles in left side high level through after conductive segment, right side hoodle, spring and the wire of key, five transistor bases that are connected with five row's hoodle interfaces (20～24) will obtain high level.When key the first tooth section and the 5th row's lock right side hoodle contacts, see the left figure of Fig. 7, emitter stage Q1e, the Q4e of triode, Q5e, Q6e, Q7e current potential are respectively 00010.When key the first tooth section and the second tooth section contact with lock right side the 4th row and the 5th row's hoodle respectively, see the right figure of Fig. 7, the emitter stage current potential of triode is respectively 00001.Key injects in the process of lock core below 5, and the emitter stage current potential of triode is followed successively by 00010,00101,01010, and these current potentials will be passed to identification circuit, see Figure 11.The current potential that is input into identification circuit is listed as into truth table 1.

Truth table 1

Be below that the buzzer warning tamper-resistant function realizes the description that circuit carries out, this comprises power circuit and two parts of function realizing circuit, and power circuit is designed on circuit board A, and function realizing circuit is designed on circuit board B, sees Fig. 8.

The working condition of each circuit of circuit board B of the present utility model in true and false key reeve lock core process:

(1) tamper-resistant function realizes circuit and buzzer warning function realizing circuit

A, the utility model do not have key inject in lock core in situation tamper-resistant function realize circuit and buzzer warning function realizing circuit working condition as follows:

Realize in circuit in tamper-resistant function, see Fig. 8, the emitter stage Q1e current potential of triode Q1 is low level, this low level is passed on two the input A4 and B4 that is connected with wire with door chip U4, U4 output Y4 passes to the low level of output on the D7 end of latch U3, according to the character of latch, its output Q7 will be low level.This low level is transmitted on triode Q2 base stage Q2b, the triode cut-off, and ironcore choke 18 must not be electric, do not form magnetic field, armature 16 does not have electromagnetic attraction, is fixed wtih motionless with the latch hook 17 of armature by latch hook spring 13, latch hook 17 does not hook newly-increased lock ring mouth 14, does not form self-locking.

In the buzzer warning function realizing circuit, see Fig. 8, emitter stage Q4e and the Q5e current potential of triode Q4 and Q5 are respectively low level, and this low level is passed to respectively on two input B2 and A2 with door chip U4, and the current potential of the output Y2 of U4 is low level.Because triode Q4 base stage is low level, the triode cut-off, buzzer LB1 does not report to the police.

B, the utility model inject in the lock core process at true key, when first three row's hoodle of first three tooth Duan Yusuo left and right sides of key contacts tamper-resistant function realize circuit and buzzer warning function realizing circuit working condition as follows: see Figure 11.

When the first tooth section of true key and the 3rd row's hoodle contacts, emitter stage Q1e, the Q4e of triode and Q5e current potential are 000, according to truth table 1, the output port Y4 of the U4 in identification circuit and Y2 be output low level, because the LE terminal potential of latch U3 is that Q5e controls, Q5e is low level, so the output Q7 of latch is low level, output latch hook 17 is fixed wtih motionless by latch hook spring 13, do not form self-locking, due to triode Q3 cut-off, buzzer LB1 does not report to the police again.

and then the hoodle of true key the first tooth section and second row, when the second tooth section and the 3rd row's hoodle contacts, emitter stage Q1e, Q4e, the Q5e current potential becomes 001, according to truth table 1, the output port Y4 of U4 in identification circuit and Y2 be output low level, the Q5e that controls latch LE terminal potential is high level, character according to latch, when the LE end is high level, level on its output Q7 is critical to be changed with the upper level of input D7, because Q1e is low level, so the output Q7 of latch is low level, output latch hook 17 is fixed wtih motionless by latch hook spring 13, do not form self-locking, again due to triode Q3 cut-off, buzzer LB1 does not report to the police.

the first tooth section of true key and the hoodle of first row contact, when namely key has all injected in lock core, the emitter stage Q1e of triode, Q4e and Q5e current potential are 010, according to truth table 1, output Y4 output level in identification circuit and output Y2 output level will be low level entirely, in this process, the current potential of the LE end of latch U3 has experienced from the low level to the high level again to low level variation, the data mode of input port D7 when the Q7 end will keep the LE terminal potential of latch to be high level, the current potential of latch input D7 is low level always in the process of true key reeve core, character according to latch, the current potential of LE end is during from high level to low level, when latch has been high level to the LE terminal potential, the low level of its output Q7 end has latched.Output latch hook 17 is fixed wtih motionless by latch hook spring 13, do not form self-locking, and due to triode Q3 cut-off, buzzer LB1 does not report to the police again.

When key all injected 5 li of lock cores, lock core and lock body 2 had formed upper and lower hoodle defiber, and lock core just can rotate in lock body.after rotational lock core, the upper lower pellet 8 on lock right side, 9 will separate (see figure 5), under the elastic force of spring 26 on the left of lock, lock left side hoodle 27 and lock right side lower pellet 9 and will contact with lock core 5, due to around hoodle and the material of lock core be insulation materials, metal material left side hoodle and the middle partition that isolator has been arranged of lock right side lower pellet, lock right side lower pellet just can not get electric, this moment emitter stage Q1e, Q4e, the Q5e potential change in true key rotation lock core that moment by being 010 to become 000, the output Q7 of latch U3 and output Y2 or the low level of U4, in this process, the current potential of the LE end of latch U3 keeps low level, the data mode of input port D7 when the Q7 end will keep the LE terminal potential of latch to be high level, so its output Q7 end is low level, output latch hook 17 is fixed wtih motionless by latch hook spring 13, do not form self-locking, again due to triode Q3 cut-off, buzzer LB1 does not report to the police.During injecting lock core then rotational lock core is opened the whole process of lock, key as the medium of conduction, makes a key that two kinds of functions be arranged again both as the instrument of unblanking from true key.

C, the utility model inject in the lock core process at false key, and when first three row's hoodle of first three tooth Duan Yusuo left and right sides of key contacts, tamper-resistant function realizes circuit and buzzer warning function realizing circuit are how to realize its function:

Realize in circuit in tamper-resistant function, suppose that the thief takes out profile of tooth but false key that through insulating segment and conductive segment process the same with true key and do not unblank, because false key is that simple metal is made, inject in the lock core process at false key, three transistor emitter Q1e, Q4e, Q5e potential change will be followed successively by 001,011,111, be just 011 at that moment at three emitter stage current potentials, the output Y2 of U4 becomes high level by low level, buzzer begins to report to the police, make the thief become nervous, dare not continue again picking lock.the no one hears alarm sound if the thief finds surrounding, the thief begins again to continue picking lock, after the thief all injects lock core with false key at that moment, three transistor emitter Q1e, Q4e, the Q5e potential change will become 111 by 011, the current potential of the LE end of latch U3 is high level, and the input D7 of U3 has become high level by low level, because its output Q7 can change along with the variation of D7 level, the Q7 end just becomes high level from low level, triode Q2 conducting, ironcore choke 18 electric generation magnetic field, armature 16 has just had electromagnetic attraction, latch hook 17 clockwise direction under the effect of electromagnetic attraction with armature rotates, hook newly-increased lock ring mouth 14, thereby just formed self-locking.That moment after the thief is with key rotation lock core, three transistor emitter Q1e, Q4e, Q5e potential change will become 000 by 111, the data mode of input port D7 when the Q7 end will keep the LE terminal potential of latch to be high level, during key rotation lock core, the output port Q7 of U3 keeps the output high level, self-locking can not removed, because triode Q3 cut-off, buzzer LB1 has stopped warning.

The thief finds that lock both can report to the police during with the false key unlocking of simple metal, again can self-locking, and have to extract key and leave this place in case caught by the people, if extract key, must first rotational lock core, key just can be extracted in the position before lock core being turned to unblank.Just at rotational lock core at that moment, three transistor emitter Q1e, Q4e, Q5e potential change become high level by the 000 output Y2 that becomes 111, U4, and buzzer begins again to report to the police.With it simultaneously, the current potential of the LE of latch U3 end is got back to high level from low level, and the current potential of D7 end becomes high level, and according to latch character, the Level hold high level of Q7 end is constant, and self-locking is not disengaged.Along with key is extracted in lock core, at first the first tooth section of key separates with the lower pellet of first row, three transistor emitter Q1e, Q4e, Q5e potential change become 011 by 111 at that moment, the output Y2 of U4 is high level, and buzzer keeps reporting to the police, and the current potential of the D7 end of latch becomes low level from high potential, and the current potential of the LE of latch U3 end remains high level, according to latch character, the current potential of the output Q7 of latch becomes low level from high potential, self-locking releasing.And then the first tooth section of key is separated with the lower pellet of second row, three transistor emitter Q1e, Q4e, Q5e potential change become 001 by 011 at that moment, the output Y2 of U4 is low level, the buzzer stop alarm, the electronegative potential of the Q7 end of latch U3 remains unchanged, and remains to be in the releasing self-locking state.And then the first tooth Duan Yudi three rows' of key lower pellet separates again, three transistor emitter Q1e, Q4e, Q5e potential change become 000 by 001 at that moment, the output Y2 of U4 is low level, the buzzer stop alarm, and the current potential of the LE of latch U3 end has become low level, the low level state of input port D7 when the Q7 end keeps the LE terminal potential of latch to be high level also is in the releasing self-locking state this moment.

The thief extracts after false key just stop alarm of buzzer, the purpose of this design is the electricity of conserve batteries, and false key is pulled out self-locking and automatic releasing after lock core, and the purpose of this design is the state before allowing lock return to the thief to unblank, and makes the true key can the smooth opening lock.

If the thief is after unblanking successfully not pull up false key and leaving, for various reasons, the self-locking of lock is not disengaged.This moment, owner also can open lock with true key.When owner injects lock core with key, before the first tooth section of true key touches the 3rd row's lower pellet, the output Y2 of U4 is low level, buzzer is not reported to the police, current potential or the low level of the D7 end of latch U3, the current potential of the LE end of latch U3 is low level, and because lock was prized by the thief, the current potential of the output Q7 end of latch has been latched as high level.Slowly be inserted in the process of lock core at true key, when the first tooth section of true key contacts with the lower pellet of second row, three transistor emitter Q1e, Q4e, Q5e potential change become 001 by 000, the output Y2 of U4 is low level, buzzer is not reported to the police, and the current potential of the D7 end of latch keeps low level, and the current potential of LE end becomes high level from low level, the potential state that the potential state of Q7 end follows the D7 end closely has become low level, self-locking releasing.When true key all injects lock core by the time, three transistor emitter Q1e, Q4e, Q5e potential change become 010 by 001, the output Y2 of U4 is still low level, buzzer is not reported to the police, and the current potential of the D7 end of latch keeps low level, and the current potential of LE end becomes low level from high level, the low level state of input port D7 when the Q7 end keeps the LE terminal potential of latch to be high level, when taking seriously key rotation lock core, because self-locking is disengaged, owner just opens lock very smoothly like this.The purpose of this design is to prevent because the thief but allows true key normally not unblank with the caused self-locking of false key unlocking.

According to above narration, the thief not only reports to the police with the false key unlocking of simple metal and goes back self-locking, and owner does not only report to the police with true key unlocking can also be with the lock smooth opening of self-locking.But the thief is without the false key of metal, but do not unblank with profile of tooth but nonmetal false key that process through insulating segment and conductive segment the same with true key, the thief just can find lock can be opened fully and neither also not self-locking of warning of lock in whole process with this key, if just can open lock very smoothly with this nonmetal key.In order to address this problem, the utility model has designed again radio warning function and has realized circuit and wireless alarm receiver circuit, sees Fig. 9 and Figure 10.

(2) radio warning function is realized circuit and wireless alarm receiver circuit

A, the utility model do not have key inject in lock core in situation tamper-resistant function realize circuit and buzzer warning function realizing circuit working condition as follows:

In the circuit of radio warning function, see Fig. 9, because the 4th row's hoodle of lock is more special, lock left side the 4th row's hoodle of number from top to bottom contacts mutually with the 4th row's lower pellet on right side always, so the 4th row's hoodle interface 23 current potentials are not high level in the situation that have key to insert always, the triode Q6 conducting that is attached thereto, its emitter stage Q6e is high level; The 5th row's lower pellet due to the 5th row's hoodle and right side is separated from each other again, so the 5th row's hoodle interface 24 current potentials are low level, the triode Q7 cut-off that is attached thereto, its emitter stage Q7e is low level, the current potential of emitter stage Q6e and Q7e is passed to U5 XOR gate chip and U6 whether after the door chip, the current potential of the output Y2 of U6 is low level, the Q8 cut-off, the power end ground connection of U7 coding chip PT2262 and U8 less radio-frequency transmitter module F05V must not be electric, and U8 less radio-frequency transmitter module F05V can not launch radio.

The utility model injects in the lock core process at true key, when the insulating segment of key and conductive segment contact with rear two row's hoodles of lock left and right sides successively radio warning function realize circuit and the wireless alarm receiver circuit operation as follows:

Key injects in the lock core process, the first tooth section the at first with five row's of true key hoodle contacts, the emitter stage Q6e of triode and Q7e current potential are 10, according to truth table 1, whether door chip U6 output port Y2 output low level in identification circuit, triode Q8 cut-off, U7 and U8 power end ground connection, less radio-frequency transmitter module F05V can not launch radio wave.When and then true key the first tooth section and the 4th row's hoodle contacts, the emitter stage Q6e of triode and Q7e current potential are 01, according to truth table 1, the whether door chip U6 output port U6Y2 output low level in identification circuit, the less radio-frequency transmitter module can not be launched radio wave.Then true key the first tooth section contacts successively with first three row's hoodle, until key all injects in lock core, in this process, the emitter stage Q6e of triode and Q7e current potential are 01 or are that 10, U6 output port Y2 output is all low level.So when unblanking with true key, less radio-frequency transmitter module F05V does not work.
