Description

A kind of tapered end

Technical field

The present invention relates to a kind of tapered end, establish more precisely and a kind of secondary key lock head (illustrating in background technology below about " secondary key ").

Background technology

The structure and working principle of the common spring tapered end be widely used at present is such: in lock body, be provided with rotary lock core, with the through lock core of row and the marble hole of lock body, in each marble hole, be all provided with an interior pellet (referring to that lock core is by the pellet stayed after rotating in lock core) and outer pellet (referring to that lock core is by the pellet stayed after rotating in lock body) and can to the marble spring of the inside pressure of (to the keyhole in lock core) of pellet one.Lock core is by the pellet pinning in marble hole in lock body at ordinary times, and lock core can not rotate.If inside and outside pellet to be regarded as the columned lock core pin be inserted in marble hole, the contact position of so inside and outside pellet just can regard the breakpoint of this lock core pin as, for the ease of describing, below referred to pellet breakpoint.That is the pellet in each marble hole has a pellet breakpoint.When tapered end is in the lock state, usual pellet breakpoint all can not on the contact surface (both fitting face) of lock core and lock body, and such lock core and lock body are also just in by the state of pellet pinning.When unblanking, key is inserted in keyhole, each key bit on the key respectively jack-up correspond each in pellet, thus the position of each pellet breakpoint is adjusted.If the key inserted is the key of this lock, so all pellet breakpoints are just just in time all on the contact surface of lock core and lock body, now twist key, lock core just can be (convenient in order to describe with key turns, below the point that now key bit contacts with pellet in each respectively is all called pellet anchor point), lock also just opens.If what insert is not the key of this lock, so each would not be all on the contact surface of lock core and lock body by the pellet breakpoint of jack-up, such lock core and lock body still can by pellet in some or certain or outer pellet pinnings, and thus lock core just can not rotate, and lock also would not be unlocked.Such tapered end, due to the relation of self structure, while applying certain torsion to lock core, stirs interior pellet by instrument, and each pellet breakpoint can be made too to be all on the contact surface of lock core and lock body.That is also can implement non-destructive to tapered end when not using this lock key to open.This unlatching of usual title is technical opening.

People had done many research for the anti-technical opening of tapered end in recent years.Utility model 200420009102.1 patent discloses a kind of tapered end (this utility model is referred to as Atom lock, convenient in order to describe, below by this patent referred to as atomic lock).Its structure is such, in lock core, the same side of all interior pellets (being called inserted sheet in atomic lock) is all provided with more shallow camouflage breach and darker password breach (being called inserted slot in atomic lock), and is provided with one in interior pellet side jaggy and distinguishes that chip (is called card in atomic lock.The present invention is referred to as according to its function and principle and distinguishes chip, distinguish that chip comprises its equivalent described in the present invention, and be not defined as tablet), this distinguishes that chip is perpendicular to interior pellet, distinguishes that the opposite side of chip is provided with the steel ball (also can be called the lock core pin of steel ball shape) as lock core pin; On lock body, have groove in the corresponding position with steel ball.Tapered end, when locking, under the effect of return spring distinguishing chip, distinguishes that chip leaves interior pellet, and steel ball is withstood on the latched position (both steel ball was in a part in lock core, the position of another part in the groove of lock body) between lock core and lock body.When unblanking, key is inserted in keyhole, each pellet anchor point on the key respectively jack-up correspond each in pellet, thus the position of the password breach in each on pellet is adjusted.If the key inserted is the key of this lock, so each by the password breach after adjusting will while with distinguish that chip aligns.If now twist key, lock core will drive steel ball to move while with key turns, due to inclined plane principle, steel ball will be extruded the groove of lock body, radial motion is done at center to lock core, simultaneously by distinguish the radial direction of chip along lock core push password breach (below, convenient in order to describe, this is distinguished chip and is called towards the motion of password breach and distinguishes a yard action by the present invention, referred to as distinguishing code, otherwise is called return), final steel ball leaves latched position, whole retraction lock core, thus enable lock core continue to follow key turns, tapered end is also opened immediately.When unblanking, if the key inserted is not the key of this lock, password breach on so interior pellet would not simultaneously with distinguish that chip aligns, when twisting key rotation lock core, steel ball is when promoting to distinguish that chip is distinguished yard, distinguish that chip will be blocked by pellet in some or certain, steel ball also will because of can not whole retraction lock cores by distinguishing chip to withstand.Lock core and lock body still can by steel ball pinnings, and thus lock core just can not be rotated further with key, and tapered end also just cannot be opened.The improvement core of this tapered end is, do not rely on pellet and carry out pinning lock core, but with the password breach on interior pellet, the key of key is converted to the another kind of key be made up of password breach, then rely on this key by distinguishing that chip controls steel ball, can opening of final control tapered end.The advantage of this tapered end is: due to interior pellet being provided with camouflage breach, thus add the difficulty of technical opening.Weak point is: its steel ball and distinguish that chip can only do radial motion in lock core, and consider the force-bearing situation distinguishing chip, steel ball has to be arranged on pellet region, makes part placement very narrow.Because the radial space of general lock core is all smaller, therefore steel ball and distinguish that the range of movement of chip is also very little, causes steel ball to expose the part of lock core little, thus have impact on the reliability of tapered end.And the part exposing lock core due to steel ball is little, cause the chamfer/lip of the groove on lock body bigger than normal for the pressure angle of steel ball, so run into unblank by force time (being exactly when twisting lock core by force with the spanner of the key shape of steel), steel ball is together with distinguishing that therefore chip can be subject to the power of the power many greatly (even manyfold) than twisting lock core, steel ball can be got into lock core by this power by force, finally causes tapered end to be opened by force (the online disclosed quick unlatching method for this tapered end just so at present).In addition, when twisting lock core by force, the pressure suffered by steel ball can by distinguishing that chip is applied on interior pellet, and likely all concentrate and be applied in certain on pellet, therefore distinguishes that the edge of chip and password breach easily sustains damage.This have impact on the reliability of tapered end too.In addition, atomic lock distinguishes chip and steel ball to hold, and has open to run through elongated slot in the side of lock core, and cause the cross section of lock core to become C font, this also greatly reduces the bulk strength of lock core.

Above describe in, relate to two kinds of lock core pins: the lock core pin of steel ball shape and columned lock core pin, both differences are: the lock core pin of steel ball shape is when being subject to the active force in opposite directions of lock core and lock body, the tendency of movement in lock core can be produced, object must be had to be withstood, make it not move, it just can play the effect of lock core pin; And columned lock core pin is quite different, when being subject to the active force in opposite directions of lock core and lock body, columned lock core pin only can be subject to shearing force, unless lock core or lock body region of interest are damaged, otherwise the tendency that can not produce to the movement of any direction, therefore columned lock core pin is more reliable than the lock core pin of steel ball shape.In order to express accurately and be convenient to describe, the present invention by the lock core pin of steel ball shape and equivalent thereof if cuphead pilotage, plagiocephaly pin, angled-lift splits etc. are referred to as pearl lock core pin (also can be described as angled-lift splits lock core pin, because steel ball namely plays a part angled-lift splits); By columned lock core pin and equivalent thereof if square column pin etc. is referred to as rigidity lock core pin.

Utility model 200420014031.4 patent (this patent name is: a kind of idle type anti-theft lock, convenient in order to describe, below by this patent referred to as racing lock) is also had with the tapered end that the password breach on interior pellet changes the key of key.The advantage of racing lock is: that distinguishes chip distinguishes that code and return are axially-movables.Part placement in lock core (such as can be arranged on place away from pellet region by being controlled by the lock core pin of distinguishing chip or clutch bolt) can be improved like this.The deficiency of racing lock is: first, will distinguish that task that chip (racing lock is called secondary pellet) pushes away password breach (racing lock is called V-ring groove, V-arrangement notch) is that password breach on inner pellet utilizes the principle on inclined-plane to complete.Therefore two limits of password breach must be all inclined-planes, so the scope of password breach is larger.If consider, the sum of series of each interior pellet is differential, the degree of depth just inconvenience increase of password breach.This also just causes distinguishing that the range of movement of chip is very little, and then causes tapered end clutch bolt (racing lock is called on-of pin) when opening to insert the part of lock core also just seldom, and this just has influence on the reliability of tapered end.Secondly, for the ease of the insertion of key, also in order to reduce wear, the elastic force of the marble spring in usual tapered end is all very small.And in racing lock, by distinguish chip push away the task of password breach sometimes (such as when running into technical opening) come by marble spring.Marble spring pushed open by the password breach on interior pellet distinguish chip time, except needing to overcome the frictional force of some parts, also will by distinguishing that chip and clutch bolt compress the spring that another should have larger elastic force.The reliability of tapered end can be affected so too.In addition, this patent distinguishes chip to hold, and also has open to run through elongated slot in the one or both sides of lock core, causes the bulk strength of lock core to be destroyed.

The difference of chip of distinguishing of above-mentioned two patents is: atomic lock distinguish chip distinguish that code and return are radial motions, except time it distinguishes chip except unblanking, remaining all directly push away interior pellet by return spring if having time, the return spring most times away from interior pellet is all be in relative relaxation state; Racing lock distinguish chip distinguish that code and return are axially-movables, except time it distinguishes chip except unblanking, remaining be all pressed on interior pellet if having time, to distinguish that the spring most times that chip presses to interior pellet is all be in impaction state, it is disadvantageous that spring most times is all in impaction state for application life of tapered end.In order to describe convenient and clear concept, the present invention different distinguishes that the chip operating principle different according to it define and be called for short as follows by above-mentioned two kinds: title atomic lock distinguish that chip is that radial direction is often opened (leaving interior pellet) formula and distinguished chip; What claim racing lock distinguishes that chip is that axial normal pressure (being pressed on interior pellet) formula distinguishes chip.The longitudinal direction being so also convenient to propose with the present invention is open in usual distinguishes with axially open in usual, chip distinguishes that chip distinguishes.

Similar to the design principle of above-mentioned two patents also has other patents.Difference is: for interior pellet, and the former is referred to as inserted sheet, pellet, and the latter is referred to as hinge or blade.Inserted sheet, hinge are after lock core is rotated in fact, all stay in lock core, their roles are also all identical with interior pellet, therefore all can regard the equivalent of interior pellet as, convenient in order to describe, in the present invention interior pellet and equivalent thereof are all called interior pellet.That is, the interior pellet alleged by the present invention comprises its all equivalent.

In order to show technical field involved in the present invention more accurately, also be in order to following describe simple, understand, numerous cylinder lock (comprise hinge lock and relate to the technical scheme of cylinder lock and hinge lock) examination is divided into a key tapered end and secondary key lock head by the present invention.By the tapered end being made it to rotate by the direct pinning lock core of inside and outside pellet, namely served as the tapered end of lock core pin by pellet, be classified as a key tapered end; Convert the key of key to another kind of key by containing, then rely on this key (by distinguishing chip) to control lock core pin or/and the tapered end of clutch bolt (comprising their equivalent), be classified as secondary key lock head.Also can distinguish with or without the breach (comprising its equivalent, groove, notch, pit, hole etc. as various shape) as password with on interior pellet, without being then classified as a key tapered end; Have, be classified as secondary key lock head.

Summary of the invention

Task of the present invention is, provides that a kind of (part) is rationally distributed, the technical scheme of secondary key lock head that the bulk strength of reliability and lock core is improved.Then pass through preferably, make this technical scheme more reasonable.Again through improving a step by a step, make to distinguish that chip and interior pellet completely no longer bear the strength of unblanking by force in tapered end, thus reduce and distinguish chip and the impaired possibility of password breach, improve the reliability of tapered end further.And then tapered end can also be made to possess anti-function of opening by force.In addition, present invention also offers the scheme that this secondary key lock head can be made when constancy of volume to possess larger size of key.Finally, pellet (being called for short variable pellet) in the position that present invention also offers for its password breach of secondary key lock head can change.

Technical scheme provided by the invention is such: distinguishing in secondary key lock head is designed to longitudinal direction by chip, and (so-called is longitudinally to be different from radial direction, why be not called axis, be because it except comprise with the axial direction of the axis being parallel of lock core except, also comprise not parallel with the axis of lock core or not bery parallel oblique) move open in usually distinguish chip (for the ease of describing, below the open in usual of lengthwise movement being distinguished that chip comprises its equivalent and distinguishes chip referred to as longitudinally open in usual).Adopt the longitudinally tapered end distinguishing chip scheme open in usual, owing to distinguishing that the scope of activities of chip increases, also just make to be controlled by its lock core pin or the range of movement increase of clutch bolt, therefore improve the reliability of tapered end; Adopt the longitudinally tapered end distinguishing chip scheme open in usual, both can distinguish that the lock core pin of chip was arranged on the place away from pellet region by being controlled by, thus the situation that in lock core, part placement is short is improved, it also avoid the shortcoming needing to be removed to compress other spring by marble spring.Adopt the longitudinally tapered end distinguishing chip scheme open in usual, when inserting pellet in key adjustment, distinguishing that chip leaves interior pellet, the fault because interior pellet is made password breach not put in place by distinguishing chip to choke more can not occur.

If angle simple from lock head structure and that lock core is easy to process is considered, the open in usual of axially-movable is adopted to distinguish the scheme of chip more reasonable (for the ease of describing, below the open in usual of axially-movable being distinguished that chip comprises its equivalent and distinguishes chip referred to as axially open in usual).And, distinguish that chip distinguishes that the driving force of code obtains from pearl lock core pin according to the principle of angled-lift splits due to axially open in usual, simultaneously, axially open in usual distinguish that chip also control pearl lock core pin can whole retraction lock cores, the gradient on the inclined-plane that therefore can contact with pearl lock core pin by adjustment while designing (refer to) set the stressed degree distinguishing chip, thus stressed (being subject to distinguishing chip pressure) degree of the interior pellet of setting (can referring to Fig. 8 and Fig. 9 for ease of understanding).This also just means can obtain the power that larger (using pearl lock core pin) locks lock core when interior pellet bears less power, thus further increases the reliability of tapered end.

In addition, open run through elongated slot owing to not needing to arrange in the one or both sides of lock core, thus the bulk strength of lock core is improved.

Further improvement of these options is such, arranges respectively to be used for drive and to distinguish that the drive unit and being controlled by of chip (distinguishing code or/and return) distinguishes that the tapered end of chip opens control member (device) in tapered end.And described drive unit is driven indirectly by spring (wrap various draw together elastomeric objects) and distinguishes that chip distinguishes code.Described drive unit comprises being twisted the angled-lift splits drive unit (such as with pearl lock core pin drive distinguish the device that chip is such) that obtains power (action/process) from lock core and inserting from key the key obtaining power (action/process) and inserts drive unit.(for ease of describing, these two kinds of drive unit letters are called twisting drive unit and slotting spoon drive unit by the present invention).Described tapered end open control member (device) comprise can the pinning lock core rigidity lock core pin that makes it to rotate or/and be used for connecting the clutch bolt of lock core and other link (described link accuses the part/part/device of the no unlatching of lockmaking prodigiosin, the handsetting gear etc. as in the plectrum in door lock, the lock bolt in padlock, lock).Described rigidity lock core pin, comprises radial movable rigidity lock core pin and axially movable rigidity lock core pin; Described clutch bolt comprises push style clutch bolt and pulling type clutch bolt.

The concrete structure (or structure) of above-mentioned slotting spoon drive unit is such, part/the part/device (convenient in order to describe, the present invention is called slotting spoon actuator) be responsible for the strength that key inserts to convert to and driven and distinguish the power of chip is provided with in lock core.Inserting spoon actuator can be the projection/bending part distinguished on chip; Also can be an independently part, as: slip yoke/sliding shoe or the slide block/cylinder/steel ball utilizing inclined plane principle to arrange or the sliding piece/poke rod/slide block utilizing lever principle to arrange; The part combination that can also be made up of different part, as can reverse driving slide block combination.Insert spoon drive unit also comprise with slotting spoon actuator with the use of a kind of special key.With normal key unlike, all had at this on the key special, all pellet anchor point and specially be extended for pellet position line (convenient in order to describe, this key claim letter for line teeth key by the present invention.Position key bit being used for locate interior pellet is called pellet anchor point or pellet position line, just convenient, directly perceived in order to describe.No matter be normal key or line teeth key in fact, its position being used for locating interior pellet is not point or line, but slight plane, this plane just on line teeth key is longer.Because the precision of the size of key, the instrument processing key bit, processing is different, the differentiation therefore for normal key and line teeth key is difficult to quantize.The difference of line teeth key and normal key more should be considered from following feature/function).The feature of line teeth key is: when line teeth key is inserted lock core to certain degree of depth, and the front end of each bar pellet position line holds interior pellet corresponding with it respectively, and now in each, the height of pellet is adjusted to position; But key can also continue to insert.Continue to insert at key, until put in place in the process of (can not continue to insert), in each, pellet is held by pellet position line corresponding with it all the time, and remains original high and low position.The specific function of line teeth key is: behind internal pellet adjustment location, in the process can also inserted, when the high and low position of pellet is constant within keeping, distinguishes chip, made it to distinguish a yard process by slotting spoon actuator driving in the continuation of key.In fact, this has also said the operating principle of slotting spoon drive unit simultaneously.

Through the tapered end of above-mentioned further improvement, distinguish that chip distinguishes code because its drive unit is driven indirectly by spring, therefore distinguishing in yard process, if the password breach on interior pellet is failed and is distinguished that chip aligns, when distinguishing that chip can not move on (entering password breach), described spring just can be compressed (or stretching), the strength of unblanking so by force would not be applied to be distinguished on chip, interior pellet also just need not bear the strength of unblanking by force, thus reduce and distinguish chip and the impaired possibility of password breach, and then improve the reliability of tapered end.For adopting the tapered end of lock core pin, owing to no longer to need by lock core pin, to distinguishing that chip provides power, therefore can to adopt rigidity lock core pin, so also further increase the reliability of tapered end.For the tapered end adopting clutch bolt, because lock core can only be dallied when twisting by force, therefore tapered end has also just possessed anti-function of opening by force.Certainly, also in same tapered end, rigidity lock core pin and clutch bolt can be adopted simultaneously.

In addition, the invention allows for a kind of combined lock core pin be made up of pearl lock core pin and cushion block, its operating principle is such, when tapered end is in the lock state, pearl lock core pin (effect due to spring) is positioned at latched position, thereunder have a cushion block, cushion block blocks pearl lock core pin with the entity of lock core for backing, makes it lock core of can not retracting.Cushion block is by distinguishing that chip drives.When unblanking, distinguish chip (complete distinguish yard action while) cushion block is removed, pearl lock core pin is regracting lock core both.Because the pearl lock core pin in this combined lock core pin can be withstood by cushion block brute force, the locking therefore for lock core is comparatively reliable, and therefore the present invention is also classified as rigidity lock core pin.

In order to reduce the mutual opening rate of tapered end, will size of key be improved, increasing the quantity of pellet.In order to increase the quantity of pellet when the size of tapered end is constant, need the density improving pellet, namely reduce the distance between pellet.But in existing cylinder lock, the arrangement of pellet is all axial, when inserting key, all interior pellets all will lean on (by the key axially inserted), and key bit relies on inclined plane principle jack-up one by one, therefore necessary distance must be kept between two pellet anchor points that the front and back of key are adjacent, to ensure a having intermediate incline between two teeth.Owing to must keep necessary distance between two pellet anchor points that the front and back of key are adjacent, therefore corresponding with it interior pellet also just must keep necessary distance.So just limit the size of key of tapered end.The scheme that secondary key lock head can be made when constancy of volume to possess larger size of key provided by the invention is such: change pellet in lock core into radial direction (namely laterally) arrangement by axially-aligned.Just do not need between pellet like this to keep necessary distance in same row, can one be close to one, even can more than one interior pellet be set in a marble hole.In the lock core of general axially-aligned 6 ~ 8 interior pellets, the interior pellet of 2 ~ 4 row's arranged radiallys can be arranged, so just can the number of pellet at double and even in the raising of several times, thus drastically increase the size of key of tapered end.Certainly, if only place a horizontally-arranged interior pellet, so just when not reducing or reduce size of key less, the length of lock core can be reduced widely.

What be necessary explanation is, the said radial direction of the present invention or be transversely arrangedly just different from axially-aligned, it can also develop into (it also comprises in other words) V-arrangement, U-shaped, W shape, stairstepping, oblique and other non axial arrangement (for the ease of understanding, can referring to Figure 26,27).

The tapered end adopting slotting spoon drive unit provided by the invention to make in conjunction with clutch bolt and positioning ball, can be used in and need in pinpoint lockset (being such as provided with the antitheft door lockset of interior outside tapered end) simultaneously.

Be described further below in conjunction with drawings and Examples.

Embodiment one

Lock core outdoors in the present embodiment have employed axially slotting spoon drive unit and the pulling type clutch bolt distinguished chip and comprise line teeth key open in usual, and is provided with anti-misoperation apparatus; Door internal cylinder in the present embodiment have employed axially open in usually distinguishes chip and pearl lock core pin (this pearl lock core pin is also double makees drive unit---the axially twisting drive unit distinguishing chip open in usual); Lock core outdoors in the present embodiment and the interior pellet in door internal cylinder are arranged radially.

First referring to Fig. 1 and Fig. 2, in lock body 1, be respectively equipped with lock core 2 and door internal cylinder 2b outdoors, they are blocked by snap ring 3 and snap ring 3b respectively, make it to be drawn out of from lock body.At the middle part of lock body, be provided with plectrum 4 between lock core and door internal cylinder outdoors, plectrum 4, can rotate with side lock core for back shaft with the tail end of lock core and door internal cylinder outdoors.In plectrum 4, be provided with clutch bolt 5, clutch bolt 5 usually (when lock core is in the lock state outdoors) is positioned at an internal cylinder side, therefore plectrum 4 usually and door internal cylinder 2b link.

Locating hole 6 is provided with in lock core 2 outdoors, positioning ball 30 and control head 8 (this control head also can be a steel ball) is provided with in locating hole 6, gag lever post 7 is provided with between positioning ball 30 and control head 8, positioning ball 30 withstands in the positioning pit on lock body by retainer spring 31 at ordinary times, and lock core 2 is outdoors located.Interior pellet 10 is provided with in pellet passage 25, interior pellet 10 is provided with password breach 11 and camouflage breach 12, marble spring 28 is provided with in the spring channels 27 of almost lumping together with pellet passage 25, be provided with end cap of the spring 29 in the outer end of pellet passage 25, this plug can make three holes one.Pellet passage is exposed in the end of interior pellet 10 at ordinary times, is arranged in keyhole 9, and due to the effect of limit point 26, the part that all interior pellets expose all remains on unified height.As can be seen from the figure, lock core is provided with two rows totally 6 pellet passages of arranged radially, is provided with two interior pellets in each pellet passage, namely two rows totally 12 interior pellets.Slotting spoon actuator in the present embodiment be a kind of can reverse driving distinguish chip slide block combination, it comprises central slider 22 and turns to slide block 14, central slider 22 is arranged in the axial slideway 16 with lock pin coaxial, and axial slideway 16 is also return spring 24 and the spring channels distinguishing yard propelling spring 23 simultaneously; Turn to slide block 14 to be arranged in radial slideway 21, in radial slideway 21, be also provided with the locating piece 20 doubling as cushion block.Anti-drilling keyhole plug 15 is provided with after locating piece 20.With the distinguishing in chip chute 17 to be provided with and distinguish chip 13 of lock pin coaxial, distinguishing that chip 13 being provided with return hooks 32 and control hook 18, because return hooks 32 and distinguish the effect of yard propelling spring 23, distinguishing that chip 13 can follow central slider 22 closely and move forward and backward along the axis of lock core.Tapered end is in the lock state at ordinary times, and return spring 24 makes central slider 22 withstand locating piece 20, and what now follow central slider 22 movement closely distinguishes that chip 13 is in return state (position); Simultaneously due to the effect of central slider 22, turn to a part for slide block 14 to expose radial slideway and be arranged in keyhole 9.When unblanking, the key 33 of this lock is inserted keyhole by (referring to Fig. 6), this is a kind of line teeth key (can referring to Figure 25), when the end of key be about to touch turn to slide block 14 time, the front end of each bar pellet position line 34 on the key by each corresponding in pellet adjust to the right place, as can be seen from Figure 6, the password breach 11 of each interior pellet all with distinguish that chip 13 aligns, but now the insertion of key does not also put in place, if twist key at this moment, due to the effect of control head 8 and gag lever post 7, positioning ball 30 can not retraction lock core, so lock core 2 can not be rotated, so just effectively prevent faulty operation (therefore by positioning ball 30, namely the device that control head 8 and gag lever post 7 form is the positioner of lock core is also a kind of anti-misoperation apparatus, this device can also be reduced to the form as Fig. 5).After key insertion puts in place, (referring to Fig. 7) control head 8 just can stretch into limited pit 35 on the key, and go deep into radial slideway after being promoted by key end (relying on the principle on inclined-plane) owing to now turning to slide block 14, the principle on same dependence inclined-plane, slide block 14 is turned to promote central slider 22, by distinguishing that yard propelling spring 23 drives, central slider 22 distinguishes that chip 13 enters password breach 11, hook 18 clutch bolt 5 drawn in agreeing with mouth 19 and (can inferring from Fig. 1 of lock core 2 tail end outdoors with distinguishing control on chip, now plectrum 4 links with lock core 2 outdoors, and departed from the interlock with door internal cylinder 2b simultaneously), now twist key, positioning ball 30 can retraction lock core, lock core 2 also just can rotate, tapered end also just can be opened.If the key inserted when unblanking is not the key of this lock, password breach so in each on pellet would not simultaneously with distinguish that chip aligns, although central slider 22 still can be diverted slide block 14 and promote, but distinguish that clutch bolt 5 but can not be drawn in because distinguishing code to be obstructed by chip 13 and agree with mouth 19, so lock core 2 can only dally outdoors.Use instrument twist by force outdoors lock core 2 time, lock core 2 still can only dally outdoors, and lock core 2 also just to have possessed anti-function of opening by force so outdoors.Can find out that return spring 24 and distinguish that yard propelling spring 23 is arranged in same passage with the form of Internal and external cycle can not interfere with each other in order to ensure them and can make these two springs positive and reverse return each other in addition from Fig. 2, Fig. 6 and Fig. 7.

Referring to Fig. 8, in door internal cylinder 2b, be only provided with a row totally 6 interior pellets, in this row pellet arrange with corresponding one in lock core 2 outdoors in pellet identical, therefore door internal cylinder and outdoors lock core can share a key.Because door internal cylinder is only used to door to lock usually, in the door internal cylinder 2b of the present embodiment, therefore have employed comparatively simple pearl lock core pin scheme.At ordinary times due to the effect of return spring 36, distinguish that the pearl lock core pin 38 in pin-and-hole 37 can be withstood on latched position by the hypotenuse 39 on chip 13b, door internal cylinder 2b is also located thus.Simultaneously referring to Fig. 9, after the key inserting this lock, password breach on all interior pellets simultaneously with distinguish that chip aligns, twisting key, when lock core is twisted, pearl lock core pin 38 can move to lock core center, rely on inclined plane principle pearl lock core pin 38 to promote to distinguish that chip 13b distinguishes code and enters password breach simultaneously, because clutch bolt 5 usual (when lock core is in the lock state outdoors) is positioned at an internal cylinder side, the part of clutch bolt 5 is agreed with in mouthful 19b at door internal cylinder 2b tail end, therefore plectrum 4 (can see in FIG) now will follow an internal cylinder 2b rotation, tapered end also just can be opened (or locking).Obviously, when the key inserted is not the key of this lock, password breach would not simultaneously with distinguish that chip aligns, when twisting key, pearl lock core pin 38 is owing to being subject to the stop of the hypotenuse 39 distinguished on chip 13b and lock core of can not all retracting, and lock core also just can not be rotated.From Fig. 8 and Fig. 9, it can also be seen that (when designing/manufacturing) if change hypotenuse 39 or/and the gradient of pin-and-hole 37, just can change the stressed degree (referring to the degree of the pressure being subject to distinguishing chip) of interior pellet.

Embodiment two

Chip is distinguished in the camouflage that the present embodiment is provided with for the difficulty of opening that develops skill in lock core.Referring to Figure 10, camouflage is distinguished chip 13c and is distinguished that chip 13 is arranged in the chute 17c increased side by side, camouflage distinguishes that chip is provided with location hook 32c, distinguishing that the outer ring of yard propelling spring 23 is provided with the propelling spring 23c that chip is distinguished in camouflage, because the effect of the propelling spring 23c of chip is distinguished in location hook 32c and camouflage, it is movable along the axis of lock core that camouflage distinguishes that chip 13c can follow central slider 22 closely.As can be seen from the figure, when the key carrying out technical opening or insertion is not the key of this lock, distinguish that chip 13 and camouflage distinguish that chip 13c can be distinguished yard propelling spring 23 respectively and pretend to distinguish that the propelling spring 23c of chip pushes password breach to simultaneously, even if interior like this pellet is not arranged the tram that camouflage breach is also difficult to detect interior pellet (just), thus makes technical opening be difficult to carry out.Can not interfere with each other in order to ensure between spring, camouflage can be made to distinguish propelling spring 23c and the adjacent spring positive and reverse return each other of chip.
