Also can adopt a kind of one to wear the flat key of fin and the lockhole that is complementary with it, the position that key inserts lockhole is designed to several fins, be groove therebetween, every fin is processed into wavy, the height of crest is all identical, the trough degree of depth is all consistent, and crest, wave trough position are corresponding with marble hole and determine at random, when crest and crest or trough and wave trough position vertical when adjacent its interlude become straight line.Compare with laminar perforate key, can reduce the associated components that the pellet group is fallen, the move mode of pellet group is become by jack-up by the whereabouts.
The below is elaborated to various piece function of the present utility model and operating principle:
1. key is rectangle thin slice (thickness 0.5mm, close with the wallpaper blade, width 27mm, active length 32mm, total length 55mm, have certain rigidity and toughness), design is selected 12 position perforates at random by 24 regularly arranged positions first in the above, the number of combinations in this half hole is 270.4 ten thousand (to consider from the probability angle, same total positional number, the number of combinations of opening the half hole is maximum, and namely size of key is maximum.Be subject to the factor affecting such as overall dimension and processing capacity, total positional number is not suitable for choosing excessive).
Key piece is contained in the protective sleeve, and the side of protective sleeve has slotted hole, in-built button, and button is fixedly connected with key piece, and contacts with a steel wire, and the hand push button can make key piece eject or spring into.
2. lock core is by 6 parallel being formed by stacking of steel plate, and the hole sealing plate (7) and the superposed slide plate of unblanking (10) that wherein are positioned at the bottom are displaceable members, and the diameter of the steel ball in its thickness and all marble holes is identical, is 3mm.All the other 4 block plates maintain static.All have 24 marble holes on every block plate, aperture 3.2mm, the position is identical with key.After all steel plate stacks, can form 24 marble holes (static lower) that communicate up and down, hole depth 35mm.Pack into altogether in each marble hole 7 pellets and 1 spring, these 7 pellets are comprised of 5 steel balls and 2 cylinder-shaped marbles (length of top is 6mm, and the length of below is 7.5mm).Because the order of packing into of steel ball and cylinder-shaped marble is by position of opening design on the key piece, as shown in Figure 1, totally 12 groups of pellet group A (16), corresponding key piece the hole site arranged; Totally 12 groups of pellet group B (15), corresponding key piece without the hole site, so after the pellet group moves a certain distance by designing requirement, always be steel ball in the hole sealing plate (7), and highly concordant, so can move reciprocatingly; And just there will be two kinds of situations in the marble hole of the slide plate of unblanking (10): a kind of is that key is correct, is steel ball in its each hole, and highly concordant, so can move reciprocatingly; Another kind of situation is that key is incorrect, then has at least a cylinder-shaped marble (all the other are steel ball) can stay in the marble hole, and the slide plate of unblanking (10) can not be moved, unlatching and the locking principle of Here it is the utility model lockset.
3. lockhole (5) is positioned at the upper surface of nethermost steel plate A (4), and shape and key coupling are the narrow slit (high 0.6mm, wide 27.1mm) of a horizontal direction.Because the pellet group is packed into by vertical direction, thus narrow slit so that various unlocking tool be difficult to play a role.Do not have other small component near lockhole of the present utility model (5) and the lockhole (5) simultaneously, only steel ball possesses again anti-drilling function, and ability of resisting destruction is strong.The lockhole entrance is designed to bell mouth shape, cooperates the oblique angle of key piece front end, is convenient to key and inserts.
This kind lockhole, key structure and shape are the most obvious surface of the utility model and relatively more crucial technology.
4. key only inserts or extracts out, does not rotate, and this is the most obvious method of operating and characteristics that the utility model is different from conventional lock.The process of unblanking is to insert first key, then relies on the rotary handle an angle of 90 degrees to finish.Lockset is opened back handle and is automatically reset, and extracts key out again.The process of specifically unblanking and principle are as follows:
The utility model is provided with a cam (24).After inserting key, rotate by rotary handle band moving cam.Cam begins to rotate the 40 degree angle processes from starting point, utilize its outstanding position to promote one by one sequentially 3 forks and swing, fork more successively in the pushing lock cylinder each associated components move.Concrete sequence of movement and process are:
1. fork A (34) overcomes top spring (35) thrust and makes the pellet supporting plate (3) below the lock core move down 2.4mm, and effect is to allow the whole whereabouts 2.4mm of pellet group corresponding to hole site be arranged on the key piece.Can not fall without the pellet group of hole site above it on the key piece, but make pellet group above it 0.5mm that rises overally because of the insertion of key on the contrary.
2. no matter whether pellet falls, and in upper each marble hole of hole sealing plate (7) steel ball is arranged all the time, and diameter of the steel ball is identical with hole sealing plate thickness, highly concordant, so hole sealing plate (7) is easy to move reciprocatingly.It is 3.2mm that fork B (33) makes the mobile aperture of hole sealing plate (7) distance, causes all marble holes of its top to be sealed, and no longer communicates up and down, and the technical opening lockset is without possibility.This is key technology of the present utility model, plays a key effect aspect the technical opening preventing.
All pellets of static lower (not inserting key) lockhole top are the line of demarcation of each steel plate 0.6mm that all sinks relatively, namely is equivalent to the keyhole height.After key inserts, the pellet of the top at the key atresia place 0.5mm that rises overally.The whole whereabouts 2.4mm of the pellet at the porose place of key in the process of unblanking.This and common lockset decide displacement and the size of key obvious differences of pellet take numerical value such as 0.1mm, 0.2mm as differential preparation key, be the basic feature of the utility model technology, also are the main causes that can take the sealing of hole mode simultaneously.
When 3. key is correct, in each hole of the slide plate (10) of then unblanking after pellet falls to finishing a steel ball is arranged all also, and diameter of the steel ball is identical with the slide plate thickness of unblanking, highly concordant, so the slide plate of unblanking can move.In this case, to push away spring (19) slide plate (10) that promotes to unblank by one mobile for fork C (20).When key is incorrect, fall behind under the pellet group, have at least 1 cylinder-shaped marble (long 6mm) and stay in the slide plate of unblanking (10) hole, it can not be moved, and fork C only can compress it and unblank to push away spring (19) between the slide plate.
4. the slide plate (10) of unblanking is connected with a stoping block (18), but the two level of synchronization moves.When key is correct; stoping block (18) can move 4mm along the soffit of protecting beam (21) along with the slide plate of unblanking (10); and allow open position make the outstanding position operation of cam (24) without hindrance and can be rotated further 50 degree angles, and then drive other transmission mechanism and finish and unblank.When key was incorrect, unblank slide plate and stoping block all can not move, and stoped cam (24) to be rotated further, and namely can not open lockset.
Cam (24) can drive relevant transmission mechanism and finish follow-up unlocking action in 50 degree angle rotation processes subsequently.
5. for preventing that powerful turning handle from causing lockset destroyed, be provided with collision bead (30) and the torsional moment protective device of protecting spring (31) to form between cam (24) and the camshaft (27).When torsional moment was excessive, collision bead (30) was lifted, camshaft (27) idle running, and lockset can not be opened.
6. in the process of unblanking of rotatable handle an angle of 90 degrees, master latch and dead bolt all are pulled.Reset rear master latch of handle keeps transfixion, and dead bolt can eject under the spring tension effect.If close to the doorstep (not doing other actions) this moment, dead bolt can lock door and only have the dead bolt locking again.The equal return of slide plate (10), hole sealing plate (7) and pellet supporting plate (3) owing to unblank is so must could again open lockset with key outdoors.Can promote dead bolt at Men Nei pushes away and turns round (17) unlock deadbolt.
7. can under any circumstance realize unblanking or locking by rotation swing handle (28) in the door, the people that this function can prevent from being locked within doors can not open lockset.
8. the process of locking outdoors is without key, and reverse rotation handle 50 degree angles can be finished, and then handle automatically resets.
9. for the specific function that key technology of the present utility model is namely utilized the mobile aperture of hole sealing plate (7) distance, the marble hole that seals its top prevents the technical opening lockset, also can realize unblanking and the purpose of anti-technology unlocking with other several lock core structures:
1. the key of this scheme is constant.The unblank steel plate D (11) of slide plate (10) and the top unites two into one, be equivalent to the slide plate of unblanking is deleted, substitute the slide plate (10) of unblanking with steel plate D (11) topmost, and stoping block (18) is connected on the steel plate D (11), every group of pellet reduces by 1 steel ball simultaneously.When key was correct, steel plate D (11) overlapped with the contact surface of each relevant pellet with the contact surface of below steel plate C (9), and then steel plate D (11) can move horizontally and realize to unblank by the upper surface along steel plate C (9) in the slideway of oneself.When key is incorrect, has at least a cylinder-shaped marble and stay on the contact surface, stop steel plate D (11) mobile, namely can not open lockset.
2. the key of this scheme is constant.Hole sealing plate (7) and the slide plate of unblanking (10) one or both of reduce thickness simultaneously to 0.5mm, namely become the thin slice arm-tie (be the sealing of hole arm-tie, the arm-tie of unblanking, thicker resistance is larger), correspondingly adjust thin slice arm-tie upper and lower steel plate distance and reduce the steel ball quantity of each pellet group.Move by cam, fork or other parts pulling thin slice arm-tie when unblanking, and then drive stoping block (18) (or other types of devices) moves and finishes unlocking action.
When key is correct, the pellet height and position of thin slice arm-tie below flush with the upper surface of steel plate at place or a little less than upper surface (because pellet can not continue movement downwards, exceeding upper surface of steel plate can hinder the thin slice arm-tie and move), and the pellet of thin slice arm-tie top can be made a concession by the against the force of the spring retraction, the thin slice arm-tie can be pulled and realize unblanking.The pulling of same dependence external force resetted when the thin slice arm-tie returned.
When key was incorrect, the sealing of hole arm-tie was still removable, stayed in the arm-tie hole of unblanking and to stop it to move but have at least a cylinder-shaped marble, so can not open lockset.
This scheme and the maximum difference of former scheme be relevant pellet not with thin slice arm-tie transverse shifting, be that thin slice arm-tie (comprising sealing of hole arm-tie and the arm-tie of unblanking) passes through between the pellet.The type of drive of thin slice arm-tie is to be pulled, because of the move mode that promotes the thin slice arm-tie its stressed unreasonable, flexural strength is inadequate, so should change position, shape and the swing mode of each fork.
3. as shown in Figure 3, the key of this scheme changes.The wide 20.4mm of key, thick 4mm, length is constant.In the same side of key, the working position that inserts lockhole is designed to 4 fins, is groove therebetween.The another side of key is the plane.Be processed into wavyly on every fin, corresponding 6 positions of each crest, trough are namely designed 24 positions on the key altogether, 24 marble holes above corresponding.The height of crest is identical (3mm is with respect to trough the lowest point height) all, and the trough degree of depth is consistent (the trough bosom flushes with flute surfaces) all.Lockhole is positioned at the soffit of steel plate B (6) (thickness increase), shape and key coupling.Each pellet group forms by 6 steel balls and 1 cylinder-shaped marble.The nethermost steel plate A of lock core (4) deletes, and each pellet group all drops on the pellet supporting plate (3), and pellet supporting plate (3) no longer moves up and down, and but is fixed on the lock body on the contrary, plays and supports and position-limiting action.After this kind key inserts, the pellet height that the is in trough 1mm that all raises, the pellet that the is in crest 4mm that all raises, and the pellet group number that is on the crest is 12 (this kind situation is that crest, wave trough position are determined at random because number of combinations is maximum equally).Be steel ball and highly concordant, removable in hole sealing plate (7) hole this moment.When key was correct, the slide plate of unblanking (10) also was steel ball and highly concordant, removable in the hole, so can open lockset.When key was incorrect, hole sealing plate (7) was still removable, but had 1 cylinder-shaped marble at least in the slide plate of unblanking (10) hole and can not move, and namely can not open lockset.
Spring in each pellet group should not surpass following distance in theory from the limit travel of static state after be compacted: the Kong Zhongyi of the slide plate (10) of unblanking after all pellets are pushed to does not have cylinder-shaped marble, and the slide plate of then unblanking is removable, namely can not anti-theft unlocking tool.The displacement of pellet is the limit travel of marble spring at this moment
This programme calculates according to thickness (9mm), cylinder-shaped marble length (6mm) and the lockhole size of steel plate C (9), and the limit travel of spring reaches and is 10mm.But physical length is 9mm only under the spring static state, 4mm after the compacting, and range 5mm, impulse stroke 4mm is not so exist above-mentioned situation.
The advantage of this scheme is: reduced steel plate A (4), fork A (34), lower carriage (2) and top spring (35) that pellet is fallen; Key self mechanical strength is large, without protective sleeve; The rotatable handle angle reduces about 10 degree angles, and namely operational stroke shortens.Shortcoming is: key is larger, and it is convenient not to carry; Key manufacturing process relative complex; The height of lockhole strengthens (reaching 4mm), for the use of unlocking tool provides chance; The mechanical strength at lockhole and near position weakens relatively.But because the effect of hole sealing plate (7) is arranged, the function of anti-technical opening is still effective generally.So must be used with the function of hole sealing plate when adopting this scheme, otherwise anti-technical opening ability significantly reduces.
4. assembled scheme is about to above-mentioned each scheme Integrated using.
10. the position of keyhole only otherwise remembered that by despiteful people the utility model lockset just can antitheft.The user can be recorded in the shelter with the lockhole position, in order to the usefulness of preparation key.Such as key loss, also can reselect position of opening, the new key of configuration, and reload each pellet group (those possessing an ordinary skill in the pertinent arts all can operate), need not change a complete set of lockset.
11. for improving anti-damage ability, especially bore a hole, recycle the situation that certain instrument is stirred associated components in the lock and then opened lockset for the appropriate location at the outside steel plate of lock body (1), can be in lock body, near the locus of outside steel plate 3～5 Thin Rectangular steel discs of packing into, it is of a size of:
Long 90mm * high 105mm stamps out 2 circular holes and 1 rectangular opening above it.Wherein 2 circular holes and camshaft (27), fork axle (32) assembling, the large 1～3mm of comparable above-mentioned two shaft diameters in aperture.1 rectangular opening assembles the length in hole, the large 1～3mm of the same comparable protection beam cross dimensions of width with protection beam (21).
The stalloy that is not secured in a press that is superimposed has stronger anti-drilling function.This moment hole sealing plate (7), the slide plate of unblanking (10) corresponding adjustment of front end one side size (also can not adjust, with the dimension modifying of Thin Rectangular steel disc be: long 72mm * high 105mm, i.e. protected area minimizing).
The utility model effect

1. after inserting key, rotate by rotary handle band moving cam (24).Cam (24) begins to rotate the 40 degree angle processes from starting point, and the protuberance potential energy of cam (24) contacts and make one by one its swing successively with the end of fork A (34), fork B (33) and fork C (20).Wherein fork A (34) makes pellet supporting plate (3) move down 2.4mm, and the whole whereabouts 2.4mm of pellet group corresponding to hole site is arranged on the key piece.Can not fall without the pellet group of hole site above it on the key piece, on the contrary, because the insertion of key but makes pellet group above it 0.5mm that rises overally.
No matter 2. whether pellet falls, hole sealing plate (7) all has a steel ball in each hole all the time, and diameter of the steel ball is identical with hole sealing plate thickness, highly concordant, so hole sealing plate (7) can reciprocatingly move.Fork B (33) makes the mobile 3.2mm of hole sealing plate (7), seals the marble hole of its top, no longer communicates up and down, and the technical opening lockset is without possibility.This is key technology of the present utility model, is preventing that technical opening from playing a key effect.
When 3. key is correct, in each hole of the slide plate (10) of then unblanking after pellet falls to finishing a steel ball is arranged all also, and diameter of the steel ball is identical with the slide plate thickness of unblanking, highly concordant, so the slide plate of unblanking (10) can move.In this case, fork C (20) promotes to unblank the mobile 4mm of slide plate (10) by pushing away spring (19).When key is incorrect, fall behind under the pellet group, at least have 1 cylinder-shaped marble (long 6mm) and stay in the slide plate of unblanking (10) hole, stop the slide plate (10) of unblanking mobile, and fork C (20) only can compress and pushes away spring (19) between it and the slide plate of unblanking (10).
4. stoping block (18) is fixedly connected with the slide plate of unblanking (10), and can slide along protection beam (21) soffit, and protection beam (21) is fixed on the steel plate of lock box front and back.
When key is correct, stoping block (18) can be along with the slide plate of unblanking (10) together mobile 4mm, and allow open position make the outstanding position operation of cam (24) without hindrance and can be rotated further, and then drive mobile the finishing of driving lever (22), locking bolt arm-tie (13) and dead bolt arm-tie (12) and unblank.When key was incorrect, the slide plate of unblanking (10) all can not move with stoping block (18), stoped cam (24) to be rotated further, and namely can not open lockset.
7. be equipped with on the lateral location of cam (24) and stir pin (23), promote driving lever (22) swing by stirring pin (23) when cam turns to design attitude, and then make the mobile 30mm of locking bolt arm-tie (13) and finish corresponding unlatching of locking point.In addition, also can promote the mobile 12mm of dead bolt arm-tie (12) when stirring pin (23) in the final stage that cam rotates, finish dead bolt and open.
8. dead bolt push button (17) is fixedly connected with dead bolt arm-tie (12), and removable dead bolt push button (17) is realized the unlatching of dead bolt in doors.
9. in the process of unblanking of rotatable handle an angle of 90 degrees, master latch and dead bolt all are pulled.Reset rear master latch of handle keeps transfixion, and dead bolt can eject under the spring tension effect.Only have behind the door bolt lock regularly when closing, because the equal return of the slide plate of unblanking (10), hole sealing plate (7) and pellet supporting plate (3), so must could again open lockset with key outdoors.
10. swing handle (28) is fixed on the swing handle axle (29), the other end of swing handle (28) has slotted hole, hinged with the lower end bending part of driving lever (22) in it, mobile in order to promote back and forth locking bolt arm-tie (13), finish and lock within doors or unblank.Because the bidirectional swinging of driving lever (22) is all without hindrance, so can under any circumstance realize unblanking or locking by rotation swing handle (28) in the door, the people that this function can prevent from being locked within doors can not open lockset.
11. be provided with the torsional moment protective device that collision bead (30) and protection spring (31) form between cam (24) and the camshaft (27).When torsional moment was excessive, collision bead (30) was lifted, camshaft (27) idle running, and lockset can not be opened.Cam (24) is formed by connecting by 4 (every thick 3mm) stamping parts riveted joints and bolt; 2 middle inner circles have the wide opening of 6mm, are assembled into behind the cam in the formed square opening that (cross dimensions 6mm * 6mm) can place collision bead (30) and protect spring (31).
12. another position of cam (24) is equipped with latch-locking (25).Because after handle resets, the backward rotation of cam (24) is without hindrance, when from original position reverse rotation handle 50 degree angle, latch-locking (25) can oppositely promote driving lever (22) backswing and then promote locking bolt arm-tie (13) oppositely mobile (30mm) also to realize locking, and handle automatically resets afterwards.
13. reset tension spring (26) relies on it to the up and down pulling force of two points of cam (24), automatically resets after handle is rotated.
14. for the specific function that key technology of the present utility model is namely utilized the mobile aperture of hole sealing plate (7) distance, the marble hole that seals its top prevents the technical opening lockset, can use other several alternative structure:
1. this scheme key is constant.Substitute the slide plate (10) of unblanking with steel plate D (11) topmost, and stoping block (18) is connected on the steel plate D (11), every group of pellet reduces by 1 steel ball simultaneously.When key was correct, steel plate D (11) overlapped with the contact surface of each relevant pellet with the contact surface of below steel plate C (9), and then steel plate D (11) and stoping block (18) can move horizontally and realize to unblank in the slideway of oneself.When key is incorrect, has at least a cylinder-shaped marble and stay on the contact surface, stop steel plate D (11) mobile, namely can not open lockset.
2. this scheme key is constant.Hole sealing plate and the slide plate one or both of of unblanking reduce thickness simultaneously to 0.5mm, thereby becoming the thin slice arm-tie (is sealing of hole arm-tie and the arm-tie of unblanking, its thicker resistance is larger), correspondingly adjust thin slice arm-tie upper and lower steel plate distance and reduce the steel ball quantity of each pellet group.Move by cam, fork and other parts pulling thin slice arm-tie when unblanking, and then drive stoping block (or other types of devices) moves and finishes unlocking action.
When key is correct, the pellet height and position of thin slice arm-tie below flush with the upper surface of steel plate of thin slice below or a little less than upper surface (because pellet can not continue movement downwards, exceeding upper surface of steel plate can hinder the thin slice arm-tie and move), and the pellet of thin slice arm-tie top can be made a concession by the against the force of the spring retraction, so the thin slice arm-tie can be pulled and realize unblanking.The pulling of same dependence external force resetted when the thin slice arm-tie returned.
When key was incorrect, the sealing of hole arm-tie was still removable, stayed in the arm-tie hole of unblanking and to stop it to move but have at least a cylinder-shaped marble, so can not open lockset.This scheme and the maximum difference of former scheme be relevant pellet not with thin slice arm-tie transverse shifting, but thin slice arm-tie (comprising sealing of hole arm-tie and the arm-tie of unblanking) passes through between the pellet.
3. as shown in Figure 3, this scheme adopts another kind of key.The wide 20.4mm of key, thick 4mm, length is constant.In the same side of key, the working position that inserts lockhole is designed to 4 fins, is groove therebetween.The another side of key is the plane.Be processed into wavyly on every fin, corresponding 6 positions of each crest, trough are namely designed 24 positions on the key altogether, 24 marble holes above corresponding.The height of crest is identical (3mm is with respect to trough the lowest point height) all, and the trough degree of depth is all consistent.The nethermost steel plate A of lock core (4) deletes, and each pellet group all drops on the pellet supporting plate (3), and pellet supporting plate (3) no longer moves up and down, and but is fixed on the lock body on the contrary, plays and supports and position-limiting action.Downside at steel plate B (6) (enlarged in thickness) has the lockhole that is complementary with key.After this kind key inserts, the pellet height that the is in trough 1mm that all raises.The pellet that the is in crest 4mm that all raises, and the pellet group number that is on the crest is 12.Be steel ball and highly concordant, removable in hole sealing plate (7) hole this moment.When key was correct, the slide plate of unblanking (10) also was steel ball and highly concordant, removable in the hole, so can open lockset.When key is incorrect, has 1 cylinder-shaped marble at least in the slide plate of unblanking (10) hole and can not move, namely can not open lockset.
In this programme, the thickness (9mm) of steel plate C (9), cylinder-shaped marble length (6mm), length 9mm under the pellet group medi-spring static state, impulse stroke 4mm, range 5mm after the compacting, limit travel 10mm namely can not open lockset with the method that pellet is all pushed to.
15. for improving anti-damage ability, near the locus of the outside steel plate 4 Thin Rectangular steel discs of packing into, it is of a size of in lock body:
Long 72mm * high 105mm stamps out 2 circular holes and 1 rectangular opening above it.Wherein 2 circular holes assemble with camshaft (27), fork axle (32) respectively, and 1 rectangular opening assembles with protection beam (21).
The stalloy that is not secured in a press that is superimposed has stronger anti-drilling function.
16, camshaft (27), the upper assembling of fork axle (32) pad are in order to regulate gap and spacing.
17, utilize moving back and forth of locking bolt arm-tie (13), its right-hand member can prolong and be connected to drive to be locked up and down on the transmission mechanism of a unlatching and locking, thereby realizes multi-point fastening.
Annotate: " highly the flushing " in the literary composition refers to the pellet height and position situation that falls behind under the pellet group at the porose place of key; The pellet group at key atresia place is because of the insertion rising 0.5mm of key, and the high 0.6mm of lockhole, the corresponding upper surface of steel plate of pellet aspect ratio hangs down 0.1mm, but does not affect the operational effect of each associated components, so also claim " highly flushing ".
