Description

A kind of photoelectric combination lock

Technical field

The present invention relates to a kind of lock, be specifically related to a kind of photoelectric combination lock.

Background technology

The coded lock generally using in the market, mainly taking electronic password lock as main, no matter pure mechanical code lock is many groups of formulas, single rotating disc type or dial-up disc type, all edge in being about to be eliminated; Recently, a kind of light-operated coded lock emerges and in some areas listing, is mainly arranged on security door, but it needs luminophor to make " key ", coded lock that in fact can not be real at last.The advantage of electronic password lock be establish close, unblank more convenient, fashionable popularly, but also there is many weakness, can not jump the defeated code in position, yardage on password figure place and every is insufficient, the number of password of composition is limited, and security is not high enough, need to accompany Zhi Yi Keying spoon to be locked into row dual fail-safe; In password, there is no default value, 0 also must input as one yard, causes the rear password length of all-key input to be difficult to memory, the weakness that these are difficult to overcome, make electronic password lock can only be used for safety cabinet, particularly on family security door, be widely used and be difficult to be generalized on common door; In addition, electronic password lock has mostly used single-chip microcomputer and a large amount of electronic circuits and assembly language program(me), not only causes complex structure but also easily by professional master-hand's decryption.Emerging light-operated coded lock, although overcome some weakness of electronic password lock, the convenience and the security that use have obtained certain raising, have been promoted the use of on family security door, still, its password is not that user arbitrarily just can arrange and seem very inconvenient at any time, secondly, while unblanking, need to carry special luminophor, Bu Shi Keying spoon but essence is the effect of Fa Hui Keying spoon, concerning user, wearing luminophor and Pei Dai Keying spoon are as good as, and have lost the true meaning of the lock that accesses to your password.

The present nearly hundreds of kind of electronic password lock that emerged and that can detect in patent statute in the world, photoelectric combination lock and mechanical code lock respectively have tens kinds, except being known as, a kind of photoelectric combination lock can reach 12, all the other are all between 5 to 8, bit code in each code bit, be all 0 to 90 value or ten codes without exception, also do not find to exceed 10 yards, except the not spacing pure mechanical password bullet lock patent 201120182346.X that does not limit code.As can be seen here, the number of password forming is very limited, exactly, coded lock now, number of password is all below millions, in order to improve the security of lock, generally all increase bitting lock and do the auxiliary dual fail-safe of carrying out, does thereby the bit code on not increasing password figure place why or increasing every improve number of password and improves security? this is not only because increase the two difficulty technically, more be to increase after position, code the memory of password more difficult, unblank to need longer being difficult to of time to be solved satisfactorily, directly have influence on the practicality of coded lock.Must solve cipher memory and uncaging time problem, could break through position, code restriction, manufacturing the higher coded lock of security just has its larger more Practical significance.

Scrutinize design feature and the use demand of people to coded lock of various coded locks, have following some common recognition:

1, no matter which kind of is locked, and security is primary requirement all the time, and coded lock certainly too.So-called security, just refers to three anti-effects of lock, not only wants precautionary technology to unblank, and also wants effectively to prevent that brute force, violence from unblanking.

Since 2 is coded locks, will goes to solve lockout issue and reach very high security by the mode of pure digi-tal, and go the auxiliary dual fail-safe of doing without Zeng Jia Keying spoon lock.

3, use and will facilitate, uncaging time is short.Traditional mechanical code lock be exactly because the tiny difficulty of scale on rotating disk read, operate need meticulous and be eliminated; Dial-up disc type coded lock, because need to wait for back code after each dial-up, causes uncaging time to be eliminated compared with length; General electronic password lock now, because can not jump the defeated code in position, under certain security requirement, password numerical digit length is difficult to memory, and the additional not Portable belt and be considered to great weakness of lock Keying spoon of opening, so that it is difficult to be generalized in Domestic antitheft door or common door and uses.

4, establish close will facilitating, password figure place will be lacked and is just convenient to memory, but security performance can not reduce.Traditional various mechanical code locks are established close all cumbersome, and it is simpler that electronic password lock seems, but also can only establish by turn code, only have eight due to the highest, only have at most 10 numerals on every, this establishes password position to have lacked poor stability, if many passwords are difficult to memory, the two is difficult to make the best of both worlds.

5, the physical size of lock wants suitable, manufacturing cost is low, and namely price can not be too high.

What does is one standard of holding lock? that is exactly to want extensively to fit various installation environments, and does not limit use crowd, and who can handled easily, unblanks fast to facilitate again, but has three very high anti-effects for robber.Coded lock is not the utensil that a kind of very frequent operation uses, but a kind of semi-static article, suitably adopts the mechanical system can be more practical; It is enough large that number of password is wanted, and people's subjective sensation just can be safe.

Summary of the invention

The deficiency existing for current various coded locks, the invention provides a kind of photoelectric combination lock, optical, electrical and mechanical several mode is organically combined, substantially can meet user's various requirement, and don't leave the condition of any technology unlocking now to robber, make robber at least also at one's wit's end within a longer period.And in the various aspects such as shape size, manufacturing cost of lock, substantially the same with current commercially available coded lock.

The present invention realizes by such technical scheme:

A kind of photoelectric combination lock, this lock comprises that the password in displacement input encoder (2) and the door internal lock abdomen that door is external arranges device (1), transposition passes code device (3), deposits a yard restorer (4) and (5) five parts of open-door system.

The principle of work of this lock is: by one group of telegraph key, light-emitting component and electric battery built-up circuit one key associated with defeated code, by one group of photoresistance, diode, triode, fixed value resistance, relay coil terminals and electric battery built-up circuit two, by electromagnet and the electric battery built-up circuit three of a group relay relay end, electromagnetic lock; By optical channel piece, circuit one and circuit two are connected to a password in composition coded lock; It is exactly the on off operating mode that manually changes certain number optical channel that password is set; Input password is exactly by the on off operating mode of telegraph key in defeated code key change number light-emitting element circuit one; When certain number optical channel connects, light-emitting component is just in time luminous again, light activated element is because of being subject to the rapid drawdown of illumination resistance, circuit two conductings, and the relay relay end on this is closure just; If the relay end of the relay in each code bit is closed, circuit three is with regard to conducting, and the work of electromagnet of electromagnetic lock, picks up Electromagnetic lock, rotates door open knob and can open door lock.If the light-emitting component electrified light emitting in certain number optical channel, but optical channel interdicted, obviously light activated element is not subject to illumination circuit two just obstructed yet, and this is " lamp light road is obstructed "; Or the light-emitting component no power in certain number optical channel is luminous, and optical channel connects, obviously light activated element is not subject to illumination yet, and circuit two can conducting yet, and this is " lamp do not work light path logical "; Both, because establish code and not identical causing of defeated code value, if it is just identical with defeated code value to establish code value, will naturally decode, make the relay end closure of relay, be i.e. " light is bright, and light path is logical, conducts ".Coded lock has how many positions just to have how many relays, the relay end of these relays connects in the mode of series connection, only has the relay end of each relay in the time of closure state, circuit three just conductings, electromagnet in electromagnetic lock could be worked, and then rotates door open knob and just can open door lock.

In specific design manufacture, the constitute and function of various piece is:

Described password arrange device 1 by establishing a yard panel, photoresistance surface-mounted integrated circuit and photoresistance base plate, optical channel piece, light-emitting component surface-mounted integrated circuit and light-emitting element base seat plate, anti-dazzling screen, establish a yard handle, make zero bar and photoresistance, diode, triode, fixed value resistance, the relay of resetting form; Light activated element uses common photoresistance, quantity is 3/4 of bit code quantity, form one of coded lock as 9 19 yards locks of example use 15 photoresistance to form a line, nine coded locks just have nine such element lines, and photosensitive circuit is printed on light activated element surface-mounted integrated circuit; If code is exactly to move up and down to establish a yard handle in fact, stir anti-dazzling screen and make the anti-dazzling screen of certain number in optical channel piece open optical channel by establishing a yard handle hypomere, meanwhile, by the make zero effect of bar of reset, drive 0 yard of handle to stir the anti-dazzling screen blocking optical channel that anti-dazzling screen makes in optical channel piece 0 yard; Moving any one yard establish when a yard handle is established yard all can make 0 yard of optical channel be interdicted, return the effect because of ejector return pin in 0 o'clock and move 0 yard of reset handle, can make all non-zero code handles together swing to on one side, but different, 0 yard of anti-dazzling screen and non-zero yard of anti-dazzling screen to optical channel open with interdict just the opposite.Described password arranges device 1 and occupy in lock abdomen, in lock housing, only open wicket one establishing a yard device position, install one little lock, when establishing yard, this little lock key is also the key that emergency is unblanked simultaneously, administered by the chief leading cadre who locks at ordinary times, only everyone all forget set password be in particular cases just used as to unblank; Described triode plays the effect of amplifying the photoresistance electric current of flowing through in circuit, has its starting relay coil working smoothly.

Described displacement input encoder 2 is mounted in part outdoors, and it is made up of one group on panel defeated code button, displacement knob, displacement pointer, reset key; 19 yards of locks of example just have 18 defeated code buttons, and 0 yard is acquiescence code, is also the normal open code after resetting, and are arranged on the appropriate location by it so it is not arranged in the serial position of defeated code button; All defeated code buttons put sleeve pipe by finer wire and are connected with corresponding position push rod on transposition biography code device 3; Displacement knob puts sleeve pipe by seizing wire and is connected with a transposition biography code device, code bit pointer is riveted on one section of seizing wire walking around through fixed pulley under panel local glass window, and pointer points to 1 to 9 number of defeated code button downwards, but its meaning is now code bit instead of bit code, adopt digital shared mode here; On the appropriate location of displacement input encoder 2 panels, button put in place pilot lamp, emergency unblank keyhole, short of electricity supply socket and door open knob are also installed.

The principle that described emergency is unblanked is: four groups of electric wires of drawing from depositing yard device, are actually the on-off circuit connecting line that extracts the defeated close button of four bands; In the past 4 relay coils are drawn four groups of electric wires, are to extract 4 groups of coil connecting lines out; Drawing four groups of electric wires from relay relay end, is also to extract 4 groups of connecting lines out; Row's formula switch is each the relaying connector that circuit is required, really connects but also need key to go to rotate 90 ° of ability; That is to say, as long as the person of unblanking has correctly inputted 4 emergency passwords, just closed four telegraph keys, but circuit can not conducting, only need that key inserts and when half-twist, relay coil just forms electric power loop and conducting work, obviously it has skipped light-emitting component and photoresistance, simultaneously four relay relay ends of another circuit make work of electromagnet with the electromagnet formation series circuit of electromagnetic lock, so the handle that turns to open in the time that key is torqued into 90 ° can be opened door lock; Obviously, there is the emergency key password door lock of not opening of not knowing to help meet an urgent need, know that emergency password does not have the key door lock of yet not opening; Every, password of emergency lock is different, sets at random special purpose system paper record with being stored in the packing box of lock while manufacturing lock.

Described short of electricity supply socket, that the door lock of not opening when preventing because of internal electric source short of electricity is arranged on the external socket on panel, usually be otiose, available pressure-sensitive adhesive trade mark covers, it is that two wires of being drawn by internal electric source parallel connection connect two core sockets and form, while needs, just tear and block trade mark, connecting 9V direct supply can use; External power supply does not affect the security of lock, because be not to have had electricity just can open lock, correctly inputting password is the unique means that can unblank.

19 yards of locks, except 0 yard for acquiescence code, also have 18 non-zero codes, distribute to successively 18 buttons on panel, are called the defeated code of non-zero code button, are set to row from 1 to 9 on the panel of displacement input encoder, and lower row is from A to I; 0 yard ad hoc is reset key, is placed on non-zero code appropriate location, sequence side; Totally 19 keys on the panel of 9 19 yards of locks, obviously, 15 codes that arrange in device than password have had more 4 passwords, and we are called these 4 passwords to mislead code, and it is to select at random in 18 non-zero codes of 1-I; Mislead the setting of code, can reduce some numbers of elements and manufacture workload, also can reduce the size of each parts, and its security performance is completely unaffected.

It is to operate in a device of depositing on yard restorer 4 that described transposition passes code device 3, it is formed a line by one group of push rod, pusher catheter, after being connected with support by brace, straddle on the guide rail of depositing yard restorer 4 two ends, upper strata, the afterbody of push rod is checked the number and is connected with defeated code button by finer wire again; Described biography code, while pressing exactly defeated code button, passes to push rod by afterbody finer wire by power, promotes to deposit a yard handle swing to another side by push rod; Described transposition, while rotating exactly displacement knob, is driven and is passed code device side-to-side movement on the guide rail of depositing yard restorer 4 both sides, upper strata by seizing wire, and can arbitrarily rest at any time and in any one code bit, wait for defeated code.

The described yard restorer 4 of depositing, by forming, deposits yard handle and swings to another side as the used time being subject to passing a code device push rod, just the closure state of this bit code telegraph key is stored, because being subject to the correlation of ejector return pin, as long as there is any one non-zero code telegraph key closure, the telegraph key of 0 yard will be immediately in off-state; In the time being subject to reset force promotion, under the effect of ejector return pin, although all together swing to on one side with non-zero code handle for all 0 yard, different is, now the telegraph key of 0 decoding circuit will be in closure state, the telegraph key of non-zero decoding circuit is all in off-state, and reason is that 0 yard and non-zero code deposit that under yard handle, to deposit dynamic and static installation direction of telegraph key of decoding circuit contrary; The circuit board of depositing yard device is password and arranges the extension of light-emitting component printed circuit board (PCB) in device 1; Deposit yard device and deposit a yard telegraph key closure state of just having stored certain bit code circuit, it is not just energising immediately, after set non-zero Password Input must being completed, rotate door open knob, after closed total power switch, each circuit just can really be switched on, and often drives once lock, in fact only has the conduction time in about 1 second in each circuit, this is for saves energy on the one hand, is also in order to prevent robber's technology unlocking on the other hand.

Described open-door system 5, it comprise battery main switch in door open knob on 2 panels of displacement input encoder outdoors, door internal lock abdomen, two electromagnetic locks, tapered end control steel disc, fixation steel plate, inner rotary table and on the shift fork tool of unblanking prop up, tapered end, tapered end driving lever, door open knob location astatic spring, master lock head, doorframe tapered end hole steel disc automatically automatically.Described electromagnetic lock is made up of electromagnet, Electromagnetic lock, thrust spring, backstay; Described inner rotary table, it comprises that electromagnetism lockhole, battery main switch that the shift fork tool of unblanking on it props up, coils drive tool to prop up; Described battery main switch, occupy to lock in abdomen and props up about roughly symmetric position of inner rotary table axle center with the shift fork tool of unblanking, and is subject to door open knob dextrorotation then driving, and when door open knob is rotated 5 °-20 °, with the closed telegraph key of sliding type, telegraph key disconnects afterwards; Door open knob turns clockwise in 10 ° of-85 ° of processes, and the shift fork of unblanking is stirred tapered end control steel disc and moved right and open door lock; Door lock is locked in inhour rotation; Described Electromagnetic lock, only in the time locking door lock, fall into the lockhole on tapered end control steel disc and on inner rotary table, it only entered the lockhole on fixation steel plate and did not enter in the lockhole on tapered end control steel disc and inner rotary table all the other times, when tapered end control steel disc moves leftwards and rightwards, it just slides on control steel disc and inner rotary table; Automatically tapered end and the tapered end automatically driving lever of unblanking, only needs during as safe-guard door lock at this lock, while lock as safety cabinet class, without this device of installation.

The operation of this lock is used main points to be:

If code: under the state of not locking a door, open and establish a yard device wicket, according to one group of password deciding in advance, find successively each code bit, bit code handle is removed to the opposing party, if this position had carried out establishing code originally, should first 0 yard of handle be removed to the opposing party, advanced horizontal reset makes zero new code is set again; As think default two passwords, and carry out twice above-mentioned action, three passwords are set as wanted, carry out three above-mentioned actions; Generally do not need to arrange four passwords; Must remember afterwards to check in the code bit of oneself not establishing code whether reset and make zero; Finally, lock is locked, opened to the mode of locking a door with vacation, to check that whether password setting is correct, then writes down set password.It is best recording the mode that password raises the price taking position, if the password arranging is: 0050H0070, just can be recorded as 355H87.

Unblank: the first step, press reset zero key, be mainly to have prevented that people from pressing defeated code key carelessly before; Second step, rotation DIP knob, by the code bit at first non-zero code place of the set password of pointed, as above establish a yard 355H87, the 3rd to be 5, the 5th be that H, the 8th are 7, so, code bit pointer just points to 3, then press defeated code key 5, then rotate DIP knob and make pointed 5, press defeated code button H, again by pointed 8, press defeated code button 7, complete defeated code work, final step is that the handle that turns to open is opened door lock.This lock can start from behind defeated code forward and even start defeated code from centre, as long as meet the input upper input in corresponding position correspondence code.As above example is first the 8th input 7, and then, at the 5th input H, finally, the 3rd input 5, turning handle open door effect is the same.

In theory, this lock is the not spacing code of not limitting, and can manufacture in any number of code bits, each code bit the coded lock of any many yards can be set, but in actual applications, be advisable to manufacture 20 35 yards following combination in any locks, take into account security and defeated code button operation convenience and arrange aesthetic property, to make 6 19 yards, 6 25 yards, 7 15 yards, 7 22 yards, 8 17 yards, 8 25 yards, 9 19 yards, 10 21 yards, 12 25 yards of locks are comparatively suitable; Particularly 9 19 yards of locks, in defeated code key group, row arranges 1-9 button, lower row arranges A-I button, upper row's key had both represented code bit, represented again bit code, and a key is dual-purpose, 0 is acquiescence code, it is not set to general defeated code button but is set to specially reset key in the other position of defeated code button, no matter be that basic, normal, high end lock all can adopt this design, difference is only the material difference that lockmaking is used.

Beneficial effect of the present invention is as follows:

1, safe, easy to use, applied widely.Safe being embodied in: the number of password of 6 19 yards lock compositions reaches 47015881, the number of password that 9 19 yards of locks can form reaches 322687697779, more than 3000 hundred million, so large number of password, anyone can not be by calculating or finding out at short notice one of them random password arranging with fortune, in addition this lock does not exist computer program to help, and can only manually test and unblank, and the person that do not know of password tests a lifetime also can not find out correct password.Easy to use being embodied in: according to setting code, DIP, defeated code, DIP, defeated code, then turning handle can open the door; Password can be arranged to two, also can be arranged to three, four, but to be set to three optimums, do not need all-key setting completely, the array mode that record or memory cipher can adopt position to raise the price, arranges two yards and can be recorded as a four figures, trigram is set and can be recorded as 6 figure places, as 0G0000008 is recorded as 2G98, and for example 005000BH0 is recorded as 357B8H, is easy to remember also very safe; If really password has been forgotten, can input every lock special to emergency code, add key, can open by a lock; Key number is large, and everybody sees clearly; Routine operation, one says that everybody understands; Therefore, its is applicable to all crowds and uses, no matter old man, pupil, blind person are even all accessible.Applied widely being embodied in: due to its safe, applicable any crowd's use again, so, no matter be Domestic antitheft door, safety cabinet, or the various departments such as bank, national treasury, Guoan, military secret all can install and use, when obviously it is according to manufacture, use material difference also can adapt to more severe installation environment and use.

2, three anti-effects are fairly obvious.No matter robber adopts skilled unlocking or destructiveness to unblank, and all can not open easily door lock.Because relying on steel wire or seizing wire to add conduit with the master lock body in door, DIP input encoder is outdoors connected, can certainly directly connect with axle, steel wire or steel cable are short available several centimetres, length can reach 10 meters of left and right, the internal and external parts of door is conventionally without rigid connection, between each several part element with shallow contact, disconnected indirect association, even also cannot open so adopt sledgehammer to pound the door, if adopting oxycut sawing to intercept a Men Tihou unblanks, also the master lock body in door can not a step prove effective, because might not be arranged on the positive back side of DIP input encoder.

3, manufacture simply, cost is lower.In the present invention, using more light-emitting component is light emitting diode or LED bulb, common triode, conventional, electric-resistance and photoresistance, they just somewhat or one of money more than a jiao, relay, electromagnet in electromagnetic lock is also one of one or two yuan, these have special manufacturer production, good and cheap, if mass customized production, cost can also further reduce, remaining parts needs oneself to produce, without special machine and special material, if not the lock that is used in particular surroundings use, optical channel piece, anti-dazzling screens etc. only need black duroplasts to make, so its manufacture is very simple, lower cost.

4, energy-conservation, saving, environmental protection.The battery main switch of this photoelectric combination lock is arranged on door open knob and rotates 5-20 ° time, that is to say, not rotating before door open knob is to open total power switch, defeated when code is only to allow the closed off-state of depositing yard device and changed telegraph key, deposit a defeated code information in, inreal energising, therefore lock itself does not have standby power consumption.If need to show such as the instruction etc. that puts in place of time on date, the code bit instruction of defeated code place, defeated code button, can separately add a low-voltage dc power supply.This lock is except installing and using as safety cabinet, Domestic antitheft door, practical especially as unit, storehouse gate lock, not only can reduce burden and trouble that managerial personnel carry many keys, the more important thing is and be convenient to control, once being surpassed the people of scope, discovery lock cipher knows, reset immediately password, greatly reduce the waste of changing lock core because of key diffusion.

Brief description of the drawings

Be five ingredient framed structure schematic diagram of photoelectric combination lock as shown in Figure 1, (1), for establishing a yard device, can carry out pre-seting of password in the time that coded lock is opened; (2) be displacement input encoder, before unblanking, converted code bit, pressed defeated code key-press input password by rotation displacement knob, the handle that finally turns to open can be realized the open and close of door lock; (3) for transposition passes code device, it is connected also convertible self place code bit by conduit wire rope with displacement knob, the power that the defeated code of its acceptance button tail rope transmits deposits by becoming the change of code push rod the state of depositing yard handle in yard device, deposits the break-make of decoding circuit preserve encrypted message to realize; (4), for depositing a yard restorer, it records on the one hand to preserve and passes the defeated confidential information that code device transmits, and in the time being subject to reset force, all encrypted messages of having inputted is resetted and is made zero on the other hand; (5) be open-door system, it coordinates to realize the open and close of door lock with electromagnetic lock by being arranged on door open knob in displacement input encoder.

Fig. 2 establishes yard device along any code bit A-A axial, cross-sectional view, Fig. 3 is the enlarged drawing of a section wherein, as seen from the figure, if the Ma Qi the superiors are for establishing a yard device panel 11, the second layer is photoresistance pedestal and printed circuit board 13, one deck is optical channel piece 14 below, bottom is light-emitting element base seat and printed circuit board (PCB) 18, if code handle 12 runs through between one or two layers and inserts in the aperture of anti-dazzling screen one end, the anti-dazzling screen 16 that insertion can side-to-side movement in the middle of optical channel piece, 15 is light-emitting component, 17 is photoresistance, 19 for establishing a yard handle rotating shaft, 20 for ejector return pin just visible in another sectional view.

Fig. 4 establishes the sectional view of yard device along code bit B-B direction, and A-A cross section and B-B cross section are orthogonal.Fig. 5 is the enlarged drawing of a section wherein, as seen from the figure, if the essence of code is exactly manually to move to establish a yard handle and swing to another side, provoke anti-dazzling screen and move right by establishing a yard handle hypomere, open optical channel, meanwhile, under the effect of ejector return pin, inevitable interdict immediately 0 yard of optical channel, this is because 0 yard of anti-dazzling screen is former in same one end with the light hole on non-zero code anti-dazzling screen, from Fig. 6 and Fig. 7 relatively.

Known in conjunction with Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 and Figure 10, move 0 yard of handle to the right, all yard handles of establishing all can be rushed for the right, Here it is, and reset is made zero, because the light hole position on anti-dazzling screen is different, while making zero, have the optical channel conducting of 0 yard only, all non-zero code optical channels all will be interdicted; If when code, yard handle of establishing of default certain yard is swung to the left side, and the code handle on side can be not servo-actuated, only has 0 yard of handle to swing to together the left side thereupon, and now anti-dazzling screen has been opened the optical channel of code presupposition, has but just interdicted 0 yard of optical channel.

Figure 11 is light-emitting component and the printed circuit diagram of depositing yard device.9 19 yards of locks of example from left to right, from 1 to 7 yard of arrangement in order of bit code, the 8th yard is 0 yard of acquiescence, the 9th to 15 yards is latter 7 yards, also having 4 yards is to generate at random from 18 bit codes except 0, they are not arranged in establishing in code value on to nine, but in unified No. 0 bit code receiving the tenth.In other words, password is set, in fact can only from except 0 yard, mislead code 14 code values select, but this is enough, if need not mislead code can certainly, but that code bit can become is longer, the apparent size of lock also can increase thereupon, and security performance is the same, Here it is uses the pleasant place place that misleads code.The left end of circuit board is light-emitting component P.e.c., and right-hand member is the P.e.c. of depositing yard device, and on it, arranging of bit code is mirror, and design is in order to avoid crossing elimination like this.

Figure 12 is photoresistance printed circuit diagram, relay is also arranged on this circuit board, between each code bit, circuit is relation in parallel, each code bit is used a relay, 9 19 yards of locks of example add that misleading code code bit has ten, use 10 relays, between the relay end of relay, be series winding relation.Be not difficult to find out, the condition of unlock circuit three conductings is that the relay end of each relay wants closed; Establishing in yard device, 0 yard of optical channel of acquiescence is normal open, and it is also normally closed depositing that 0 decoding circuit of giving tacit consent in yard device resets after making zero, so only otherwise input non-zero code, the relay end of relay is just certainly closed; If establish in yard device and be provided with non-zero yard in certain code bit, this yard just opened optical channel and interdicted immediately the optical channel of 0 yard simultaneously, make the relay end closure of this relay, just only input this code this from input encoder, closed this yard, at the telegraph key of depositing in yard device, makes light-emitting component luminous, otherwise, relay on this just can be not closed, and whole piece unlock circuit three disconnects; If the tenth in code device is only had one 0 yard, its optical channel is normal open, the tenth that deposits in yard device is also only had one 0 yard, all button tail ropes that mislead code all point to it, when input password, do not input and mislead code, and this relay is closed, mislead code once input any one, relay on the tenth has just disconnected, and whole unlock circuit three is also just obstructed, then input any password all dual lock be useless; If inputed the password door lock of not opening by mistake, re-enter proper password after can pressing reset key, can open and lock; Just in case really forgotten password completely, that just can only input while buying lock in packing box to emergency code, then insert and establish 90 ° of yard key turns of device wicket and do not let go, another hand rotates door open knob can open door lock.Electromagnet in the electromagnetic lock of 541 in figure and 542 expression open-door systems.In password arranges device and deposits yard restorer, be all provided with the 10th and mislead code bit, arrange in device the 10th at password and just only have one 0 yard, can not arrange and can not reset, normal open code completely, depositing in yard restorer, although also only have one 0 yard, completely likely pressed and mislead code and make it telegraph key and close by others, visible its telegraph key might not be normally closed, therefore, always it resets and makes zero with nine bit synchronizations above.

Figure 13 is a circuit diagram in code bit.In figure after 15 photoresistance parallel connections in place in circuit, no matter be reset mode or establish a yard state, always only have an optical channel not interdicted, accept illumination so also only have a photoresistance, except photoresistance, in circuit, also have diode, triode, fixed value resistance and relay actuating coil.

Figure 14 is displacement input encoder panel outdoors.21 is that displacement knob, 22 is that DIP pointer windowpane, 23 is that DIP pointer, 24 is the defeated code of non-zero code button group, by 18 buttons form, 25 for reset key, pressing it, to be equivalent to input in each code bit 0 yard, 26 be the defeated code button pilot lamp that puts in place, the defeated code success of the bright expression of lamp, 27 for the emergency keyhole, 28 of unblanking be external electric supply socket hole.Described displacement knob 21 use seizing wire with well passes code device with the transposition in lock abdomen and is connected, and turning knob will drive biography code device on guide rail, to move left and right to reach the object that changes defeated code code bit by wire rope.Described DIP pointer, be riveted on wire rope by fixed pulley walk around under windowpane one section upper, pointer with pass a code device synchronizing moving, can be accurately positioned in any code bit by the steel disc that passes band depression under code device.Described defeated code button 24, finer wire by the foot section brought conduit is connected with the change code push rod that passes the corresponding bit code of code device, press defeated code button, by the power transmission of tail rope steel wire, push rod is travelled forward, yard handle of depositing that promotes to deposit in yard device pivots and swings to the left side and defeated code information is stored.Described emergency is unblanked, refer to and select four at random depositing depositing in yard telegraph key in yard device, four groups of electric wires are drawn in parallel connection, four groups of electric wires are drawn in the from the 1st to the 4th relay coil end parallel connection again, the relay end of relay is also drawn four groups of electric wires, and these electric wire groups are connected on row's formula switch according to certain rule, is inserted and is established the little door key of yard device by unblank keyhole 27 of emergency, when a hand is not let go key half-twist, another hand-screw turn-off door handle can be opened door lock; Key is subject to the effect of contained spring, goes back to original position once let go, and disconnects row's formula switch; The principle that emergency is unblanked is: four groups of electric wires of drawing from depositing yard device, be actually the switch that extracts four circuit, in the past 4 relay coils are drawn four groups of electric wires, to extract 4 groups of connecting lines out, relay relay end is drawn four groups of electric wires, also be to extract 4 groups of connecting lines out, row's formula switch is as each the needed relaying connector of circuit, and key is the driving of row's formula switch; That is to say, as long as the person of unblanking has correctly inputted 4 emergency passwords, just closed four telegraph keys, but circuit can't conducting, only need that key inserts and when half-twist, relay coil just forms electric power loop and conducting work, obviously it has skipped light-emitting component and photoresistance, another circuit is to make the relay end of relay and the electromagnet of electromagnetic lock form series circuit and make work of electromagnet, so the handle that turns to open in the time that key is torqued into 90 ° can be opened door lock.Obviously, there is the emergency key password door lock of not opening of not knowing to help meet an urgent need, know that emergency password does not have the key door lock of yet not opening.Every, password of emergency lock is different, sets at random special purpose system paper record with being stored in the packing box of lock while manufacturing lock.

Figure 15 is a transposition biography code device side-looking enlarged drawing.The 31 biography code device guide rails of depositing yard restorer both sides for straddling in figure, 32 for transposition pass a code device support, 33 for one group of rack-mount conduit, 34 for insert one group of push rod in conduit, 35 for push rod connect defeated code button sleeve pipe seizing wires, 36 for rack-mount biography code device locating pin spring, 37 for pass band depression under code device location steel discs, 38 for locating pin, 39 connection cords, 40 that pass between code device and displacement knob for transposition be steel cable break-in fixed pulley.Obviously, once wire rope is stressed, must first pull-up locating pin 38 then do side-to-side movement, once lose rope pulling force, fall to recess in spring action, this has just ensured to pass code device parks the accuracy of code bit.

Figure 16 faces enlarged drawing for transposition passes code device.From instance graph, the distributing order of visible bit code also can be found out simultaneously, and the misleading code of 9 19 yards of locks of example is 4,7, A, E, and default value is 0, placed in the middle, non-zero code can be set be 1,2,3,5,6,8,9 and B, C, D, F, G, H, I.

Figure 17 and Figure 18 are yard handle side views of depositing of depositing in yard restorer.41 is telegraph key movable contact spring in light-emitting element circuit for depositing a yard handle, 42 for depositing a yard handle rotating shaft, 43, and the bending on it plays the role of positioning to depositing a yard handle, and the movable contact spring in all each code bits links together and joins with circuit anode at its base part; 44 is telegraph key static contact spring piece in light-emitting element circuit, and each independence is also joined with the positive pole of establishing light-emitting component in yard device.Figure 17 is reset mode, and telegraph key disconnects; Figure 18 is for depositing a yard state, telegraph key closure.

Figure 19 and Figure 20 deposit in yard restorer, to give tacit consent to 0 yard of side view of depositing yard handle.The difference of it and non-zero code handle is, it,, depositing many projections on yard handle, encases ejector return pin to form an entirety, no matter when links together with ejector return pin; In addition, the telegraph key installation direction of its below is contrary, this make it closure and the off-state of telegraph key and non-zero yard to deposit yard handle just the opposite.

Figure 21 is for depositing a yard restorer side view.Because example first all has 15 yards to the 9th, 0 yard occupy in the middle of, so can only see that non-zero code deposits a yard handle, and on the tenth, only have one 0 yard, so directly just seen 0 yard of handle.In figure, 45 is that ejector return pin, 46 is that reset pulling-on piece, 47 is that reset pulling-on piece self-return extension spring, 48 is that reset pulling force rope, 49 is the ejector return pin resigning hole on reset pulling-on piece.Shown in figure, inputted non-zero code on the 3rd, the 7th, the 8th, so ejector return pin has been shifted onto to the lower left corner of resigning hole, the code bit ejector return pin of not inputting password remains on reset mode.Obviously, when the pulling force rope pulling force that is subject to resetting is done the used time, reset steel disc moves right along hanging moving ejector return pin by resigning hole is left, all deposit yard handle and can together swing to the right, is presented at the upper right corner, and this is to reset to make zero.Reset key is converted into pulling force by angular lever steel disc by pressing force power.

Figure 22 is 0 yard of handle front elevation depositing in yard restorer.41 are 0 yard deposits a yard handle, 42 for depositing all common rotating shafts, 45 of depositing yard handle of yard device for resetting shaft, 48 is reset steel disc, the 81st, helps turning handle, the 82nd, the support column of rotating shaft 42 for what force balance arranged.

Figure 23 is open-door system front elevation.In figure, 51 is door open knob, it belongs to open-door system, but it is arranged on displacement input encoder panel outdoors, clockwise rotate it prop up by the tool on inner rotary table 52 that moving contact 59 contacts with static contact 60 relative motions just can closed general supply circuit, can also prop up shift fork by another tool and stir tapered end control steel disc 57 and move right and open door lock; 53 is the fixation steel plate in lock abdomen, other parts in open-door system except door open knob are mostly clipped between fixation steel plate 53 and lock housing, 541 electromagnetic locks for locking tapered end control steel disc 57,542 electromagnetic locks for locking inner rotary table, two electromagnetic locks are connected in circuit three simultaneously; 551 and 552 is electromagnetism lockhole, and 56 is that tapered end control steel disc is limit to bar, 57 tapered end control steel discs, and .58 is Electromagnetic lock, 61 is fixation steel plate dog screw.If this lock during as safe-guard door lock, also should arrange automatic tapered end and the tapered end automatically driving lever of unblanking, for it being omitted in the succinct figure of figure.In order to ensure that open-door system electromagnet has enough work efficiencies, this lock uses 9V direct supply, and the required 3V direct supply of light-emitting component and relay, can obtain by the fixed value resistance of connecting.The door lock of not opening when preventing internal electric source short of electricity, on displacement input encoder panel, supply hub 28 is set, both positive and negative polarity is in parallel with internal electric source, seal jack with trade mark under normal circumstances, when short of electricity, opening it connects external power source again and can open the door, it can not affect the security of lock, because incorrect input password, external power supply is at all useless.

This coded lock can use general commercially available electronic components fabrication, and the quality of electronic component determines the use installation environment of lock, conventionally at-20 ° within the scope of 60 °.If require to install and use in particular surroundings, need special electronic component.Certainly, during as industrialized mass production coded lock, electronic component also need to the mass customized production of specialized factory, can allow the size of electronic component less like this, better quality so that the coded lock volume of producing is less, more reliable performance.
