Description

Non-key labyrinth lock

The present invention relates to that a kind of to need not with key operated, lock core be the coded lock of special construction, particularly a kind of password is the labyrinth array combination of arbitrarily being set up by the lockset user, have only with the probe in the lockset smoothly, inerrably transfer shift out labyrinth array after, can shooting the lock-bolt unblank, can with the alarm of setting up mutually continuous cropping open by mistake the non-key labyrinth lock of warning.

At present, common coded lock can be divided into mechanical code lock and electronic type coded lock two big classes on the market.Although their structure is ever-changing, design very exquisitely, performance is also more perfect, but all still have many weak points: the mechanical code lock complex structure, repeated code is not counted that volume ratio is less, security performance is low, is easily decoded or by strong destruction, and great majority also need bitting to unblank.The design concept of most mechanical code locks all can not break through traditional form, be that operating process all is by rotating disk or connects and can open after key is arranged ordering with sign indicating number spare, so just exist some common defectives: between each rotating disk or the button or need one to overlap independently transmission mechanism, or need common transmission mechanism to add switching mechanism, each mechanism all occupies certain working space, also needs certain insulating space to prevent the phase mutual interference.For example, general combination lock lock, is isolated the about 2mm of spacing at the about 5mm of the thickness of each rotating disk, size less than this numerical value then make get up in week just very inconvenient.The size of each button of key-type mechanical puzzle lock also must adapt with finger.Even button is digital general to everybody, also to dispose ten numbers keys and several switch key at least, must increase complicated switching mechanism, take a large amount of working spaces.By the lock object, the quilt lock object of especially civilian lockset limits to some extent to volume, like this, is guaranteeing that the repeated code number can not be not too high under the easy to operate prerequisite; Concerning the lockset designer, the main means that solve above-mentioned contradiction are to make interior each member of lock core small and exquisite, connected mode between member is peculiar, compact in design so often makes the structure of lockset complicated, moreover all double simultaneously negative definite position of the sign indicating number part of most mechanical code locks and two kinds of functions of kayser, not only require machining accuracy higher, because of the restriction in space is difficult to design very abundantly, the intensity of single part can not be very high, is subjected to powerful easy to be destroyed slightly; Simultaneously, most of mechanical ciphers are locked in the process of unlatching, can produce the different feels and the sound because of moving the sign indicating number part, are easily decoded and unblank.If do not break through the design concept of conventional form, run counter to the design principles of member exquisiteness again, its effect is on duty mutually.For example sell the market has a kind of giant's board not have the key cipher padlock, its structure is quite simple, required precision is low, and it has decode, every group 60 lattice calibration, the repeated code number is not 200,000 in theory, but because precision is not high, actual measurement significant graduation lattice only are 20 to 30 lattice, and decode is illusory, therefore its reality not the repeated code number mostly be 900 most, be lower than nearly three times of the cylinder lock set that generally has four pellets shot from a slingshot.Electronic password lock can obtain high not repeated code number by good electronic device, but repeated code is not counted volume ratio and still had limitation, is with repeated code numerical value is not proportional as the keyboard grabbing space of keyboard-type electronic password lock; The functional reliability of electronic password lock also quality and the failure-frequency with electronic device is relevant, and low with respect to machine components, the performance reliability of especially all kinds of contacts is relevant with environment for use; Electronic device also is subject to outside electromagnetic interference in addition; Electronic password lock also need be equipped with power supply, consumed energy.Also there are following deficiency jointly in present mechanical code lock and electronic password lock: when not repeated code numerical value increase, digital figure place also increases, and is difficult to memory; Cost is too high, causes popularity rate low.

Current to popularize wide be cylinder lock set easy to use, simple in structure, and cylinder lock has 2 deficiencies at least: must wear key 1.; 2. the repeated code number is not low.For the cylinder lock that five pellets shot from a slingshot are arranged, when machining accuracy was higher, the repeated code number did not have only about 30000.No matter being coded lock or cylinder lock, all is a kind of article with the relatively independent existence of user, in case be designed to create, its mode of operation also just is fixed, and its weakness also progressively leaks, so that may form the various methods of decoding and unblanking.Opening lockset is that anyone has grasped them, just can unblank by a key or one group of password.The lockset of developing that utilizes characteristics of human body such as vocal print, fingerprint, eyeprint to open constantly being arranged now, make lockset and user's sign form system, is a kind of rapid progress of lockset.The cost of this class lockset is more much higher than general coded lock, also the characteristics of human body also can change in some cases, can cause open malfunctioning.

With the technology of the present invention content approaching be a United States Patent (USP) (document number: US-3824815A).It has also adopted labyrinth structure, possess the similar techniques feature: lock core is that the axle center is arranged with the Handle axis, the labyrinth body is loop overlapping shape, at least be provided with a road, labyrinth that communicates continuously on the body of labyrinth, two ends, road, labyrinth are respectively equipped with entrance and exit, labyrinth body and Handle axis suit, probe are that entad state device is on sliding sleeve, and the inner termination of probe is deployed in the road, labyrinth of labyrinth body.But it exists significantly not enough, and consequently the mechanical cipher lockset with other does not have qualitative difference.Its probe can not be backward and laterally cross over obstacle when moving in the road, labyrinth, and running into the back is appreciable when hindering with transverse; And when crossing over the obstacle in the place ahead, owing to due to the structure of probe, also have feel, its road, labyrinth is surrounded by horizontal and vertical obstacle, as fascination or to have only outlet or have only the quantity in inlet or road, totally enclosed labyrinth be limited.As long as theft has enough patience and analysis ability, by the state that probe is obstructed, just the distribution and the shape in all roads, labyrinth roughly can be determined, open the just problem of a time.Simultaneously, it is the same with other coded locks, and when not repeated code numerical value increase, figure case also increases, and is difficult to memory.Also have, it is very difficult that lockset user oneself changes password.

The objective of the invention is to provide a kind of and need not to add that bitting is unblanked, repeated code number not to the public, especially not repeated code count volume ratio height, the easy memory of password can arbitrarily change again, can resist powerful broken lock, reliable working performance, overall structure simple, manufacture cost low, adopt contain digital content intentionally can with lockset and user's wish composition system can with set up the labyrinth lock that alarm is connected.

This labyrinth lock is that a whole set of lockset also is complete by lock core and the combination of padlock spare two parts with the lockset something in common of using always.Its lock core is to be assembled in the lock core valve jacket with labyrinth mechanism and safety component to constitute, labyrinth mechanism be used for to lockset encrypt, decryption oprerations handles, safety component is used to limit powerfully to be opened and reports to the police.Labyrinth mechanism mainly includes component such as unlocking handle axle, lining, rotating disk, probe, labyrinth body and locator.Whole lock core structure is that the axle center is arranged with the unlocking handle axle.Lining is the support of lock core, is packed in the lock core valve jacket.The labyrinth body is loop overlapping shape, is provided with a road, labyrinth that communicates continuously on the body face of cylinder, labyrinth at least, and road, labyrinth two ends is respectively equipped with entrance and exit, the labyrinth body or with unlocking handle axle sleeve dress, or be installed on the sliding sleeve.Probe entad is state device on sliding sleeve (when the labyrinth body is sleeved on the unlocking handle axle) or rotating disk (when the labyrinth body is contained on the sliding sleeve), the inner termination of probe is deployed in the road, labyrinth of labyrinth body, and different is: the outer end head of probe touches mutually with an end of moving part.The moving part direct-axis is to placement, the brake lining attaching in its other end and the safety component.Probe and labyrinth body can relatively move under the manipulation of unlocking handle axle and rotating disk: promptly can be that the labyrinth body is fixed, probe moves; Can be probe stationary also, and the labyrinth body move.The feel and the sound that probe is produced when departing from the road, labyrinth in moving are extremely slight.Locator is the elastomeric element of device on lining, its location terminal is replaced on the hole, location set in handling the parts such as unlocking handle axle, rotating disk or sliding sleeve that probe or labyrinth body move, in the process of unblanking, locator is compressed earlier, replace again again on the hole, location, all can produce the strong feel and the sound at every turn,, instruct probe in the road, labyrinth, to relatively move exactly with the position of prompting probe in the road, labyrinth.

Safety component mainly is made of brake lining, baffle plate and conductive reed, by the relevant coordination with labyrinth mechanism of moving part.Brake lining touches mutually with an end of moving part or is affixed, and brake lining is placed between projection (being guide block) set on the cylinder of unlocking handle axle front end position and the baffle plate and is close to baffle plate.Baffle plate and lock core shell cover are fastenedly connected, the centre offers the through hole of allowing that the unlocking handle axle passes, direct-axis is to offering the gap slot that matches with projection shape and sectional area on the wall of through hole, and the orientation angles of gap slot can be set up according to outlet azimuth, the road, labyrinth on the body of labyrinth when assembling.On brake lining, on the one side of baffle plate the conductive reed that insulate mutually with brake lining is installed dorsad, one causes the outer wire bonds of lock core valve jacket on reed.The normal operation position of brake lining is in baffle plate gap slot one side, in a single day the process middle probe of unblanking departs from the road, labyrinth, brake lining is just covered gap slot under moving part drives immediately comprehensively, the restriction unlocking handle is axially preceding to be contacted with bolt plate, and conductive reed is electrically contacted under the replacing of projection with brake lining, the alarm that connection is set up sends alarm signal.Only when the process of unblanking makes probe smoothly, inerrably pass through the outlet of arrival road, labyrinth, road, labyrinth, the unlocking handle axle just can be pushed ahead, the boss (being shifting block) that then is arranged on Handle axis front end head just can insert on the bolt plate, in the dial hole that is complementary with the shape and the sectional area of shifting block, dial the twist lock tongue, interlock padlock spare is unblanked.

More the sign indicating number valve is to be sleeved on unlocking handle axle middle part or the anterior part that can freely get around the rotation of lock Handle axis.On the unlocking handle axle, be close to more a sign indicating number valve leading section and be provided with fastener, move behind the restriction unlocking handle axle, and when lockset was in opening, the user was easy to remove the constraint of fastener, with the unlocking handle axle, and the labyrinth body of together with suit extracts out from the lock core valve jacket together, carries out password and changes.

Labyrinth mechanism in this neoteric lock core and safety component be interconnected lock mutually, probe is not if cover the road, labyrinth in accordance with regulations, the shifting block of unlocking handle axle is injected in the dial hole on the bolt plate unblank, and conductive reed and brake lining are electrically contacted, send warning.The structural strength of baffle plate and brake lining can withstand other people destructive brute force fully and unblank; Locator makes it can produce the strong feel and the sound in the process of unblanking, both can point out the accurate relative position of probe in the road, labyrinth, even so that the lockset user also can successfully unblank under the situation of not having illumination, simultaneously can cover the original quite slight feel and the sound that is produced when probe departs from the road, labyrinth again, other people are more difficult to decode thereby make; Labyrinth mechanism in this neoteric lock core adopts labyrinth array combination to become the design of password, is to use Chinese distinctive The book of Changes principle: Taiji growing two instrument, and two instrument are given birth to four-quadrant, and four-quadrant is given birth to Eight Diagrams, and its change of divinatory symbol divinatory symbol interpromoting relation in five elements is infinite.Each fundamental-sign indicating number part of forming labyrinth array all is the very simple bar shaped part of structure.The combination of each yard part both can be reflected as number, also can be reflected as font code, getting in touch also and can arrange between number and number, shape and shape or number and the shape according to user's wish, thus constitute the meaning sign indicating number.With the lock core valve jacket of general pin tumbler lock same size key element in, labyrinth array with nine sign indicating number spare combinations can comprise 100,000,000 numbers, constitutes 180 font codes by rotation direction, initial bit, constitute 65536 groups of meaning sign indicating numbers by counting mode, font code matches with the meaning sign indicating number and reaches 1,000 ten thousand kinds of combinations.Than big hundreds of times of the not repeated code volume ratio of general pin tumbler lock.And this is not the limit of its not repeated code number, by improving machining accuracy, increases the sign indicating number number of packages, need not enlarge any working space, and the order of magnitude of repeated code can also significantly not increase.The labyrinth array of the labyrinth body institute cloth that in the lock core valve jacket is of a size of the volume of Φ 100 * 60mm3, is provided with and for example, the repeated code number does not reach 10,000,000,000,000, its not repeated code count volume ratio and compare with general pin tumbler lock, big several hundred million times; The repeated code number increases, if be very difficult with digital memory entirely.For repeated code number not is that 10,000,000,000 numerical value will be remembered the 1O bit digital.Non-key labyrinth lock of the present invention owing to adopted font code and meaning sign indicating number, relatively is convenient to user's memory operation.The foregoing labyrinth lock that has nine sign indicating number spares, the user can also fall sign indicating number and use, and removes wherein 5 sign indicating number spares, and number is reduced to 1000, font code still is 180, original meaning sign indicating number is reduced to 64 groups, owing to reserved 5 rooms, forms the pseudo-code position, the setting of pseudo-code position is to be arranged by user's wish, thereby increased by 56 groups of new meaning sign indicating numbers, at this moment the user only need remember three bit digital, rotation direction, initial bit, counting mode and pseudo-code position, and back four are easy to remember.After falling sign indicating number, as if the not repeated code number of labyrinth lock subtracts greatly, but this means that only can to select the scheme number arranged few, and concerning pirate of the open lockset person, do not understand the user and fallen sign indicating number or which kind of mode to have fallen sign indicating number with, it is quite low that the probability of success of unblanking by force remains.User even can indicate the eight-digit number word in that lockset is other only relies on font code, meaning sign indicating number, need not remember numeral, its not the repeated code number still reach 1,000 ten thousand.People can be by the habitual movement in some daily lifes, and the speed change gear of running car term correspondence, some specific motion mode of occurring in nature, simple and distinctive geometrical pattern wait organizes into groups font code and meaning sign indicating number; After removing the constraint of fastener to the Handle axis of unblanking, the road, labyrinth on the body of labyrinth just can the wish by the user rearrange outside the lock core valve jacket, because the sign indicating number part is attached to it with the plain mode embedding, so be convenient to very much change password; The member that mainly bears destructive power in the lock core of the present invention is lining, brake lining, baffle plate and is opened in guide block on the unlocking handle axle that these members can design abundantly, select high-intensity material for use, can make lockset resist strong destruction; Existing mechanical lock, to its member of encrypting, deciphering, as the sign indicating number part in the coded lock, pellet shot from a slingshot and the key in the cylinder lock, requirement on machining accuracy height often, and in use these members are more or less frayed, and the precision overall performance that descends gradually then just descends.In the labyrinth mechanism in the lock core of the present invention, admit of bigger gap between probe and the labyrinth body, do not wear and tear in the use, can guarantee the superperformance that lockset is lasting, the requirement on machining accuracy to part is low simultaneously, and cost of manufacture is also low; In case be familiar with the program of unblanking, the time of at every turn unblanking only needs several seconds, and error code resets and operating time of opening the multiple lock in back is no more than 2 seconds, the time of when changing password the labyrinth body being extracted out the lock core valve jacket also only need ten surplus second, manipulate very convenient.Lock core structure form of the present invention can be used for door lock, Safe lock, cabinet lock and all kinds of lock.
