Description
Technical field
The present invention relates to a kind of mechanical anti-theft lock, be specifically related to a kind of baffle type mechanical anti-theft lock.
Background technology
Mechanical lock is generally by formations such as lock core, transmission mechanism and dead bolts (bolt).Lock core is critical component, includes pellet group.Action and the movement range of pellet are determined by key, only run into correct key, and pellet just can move to tram, and lock core just can rotate or other form motion, and then drives transmission mechanism to complete unlocking action.As driving force, screw key is main type of drive.Because pellet and transmission mechanism exist, necessarily contact, technical opening lockset often utilizes this contact and in conjunction with special special tool, pellet or other associated components moved to be needed position, finally lock is opened.
Common spring (or blade etc.) lock differential less, theoretical size of key is larger.But differential too small, can be because factors such as having fit clearance and mismachining tolerance makes actual available key amount not reach theoretical value.
In order to improve the protection level of theftproof lock, Most designers all makes lock core internal structure complicated as possible, and it is novel unique to strive, strengthens size of key.But it is high that general precision requires, and manufacture difficulty and cost are also high, and may cause mechanical strength to reduce, thus have also select special quality material to promote anti-damage ability.The anti-technical opening ability of lockset also having is stronger, but unlock operation process is more loaded down with trivial details.
Summary of the invention
The object of the invention is to: a kind of baffle type mechanical anti-theft lock is provided, and is achieved as follows target:
1. adopt narrow slit type lockhole, make various unlocking tools be difficult to play a role;
2. near lockhole and lockhole, only have steel ball, there is no other small component, anti-drilling, destruction-proof function is strong;
3. by hole sealing device, in time marble hole is sealed, blocks the contact between upper and lower pellet in centre, to preventing that technology unlocking from playing a key effect.
4. pure frame for movement, simple to operate, and low cost is easily manufactured.
The present invention adopts following technical scheme:
A baffle type mechanical anti-theft lock, comprises lock core and lockhole, it is characterized in that: the steel plate that lock core has marble hole by multi-disc is formed by stacking, each marble hole up/down perforation that is arranged in parallel, and vertical with the narrow slit type lockhole of horizontal direction; Lockhole (5) is positioned at the upper surface of nethermost steel plate, the hole sealing plate (7) and the superposed slide plate of unblanking (10) that are wherein positioned at bottom are displaceable members, movably hole sealing plate (7) marble hole footpath distance of transverse shifting when unblanking, seals, blocks the engagement and outreach between upper and lower pellet by marble hole in centre.
Further, on every block plate, all have 24 marble holes, after steel plate stack, form 24 marble holes that communicate up and down.
Further, pack altogether 7 pellets and 1 spring in each marble hole into, these 7 pellets are comprised of 5 steel balls and 2 cylinder-shaped marbles; Wherein pellet group A (16) is totally 12 groups, totally 12 groups of pellet group B (15).
Further, the steel plate (11) of the slide plate of unblanking (10) and the top can be integrally combined structure, in the process of unblanking along with below whole slip of contact surface of steel plate (9).
Further, hole sealing plate (7) and the slide plate of unblanking (10) one or both of all can reduce thickness and become laminar arm-tie, it only passes through when pulled between pellet, the pellet in its hole is transverse shifting thereupon not.
The present invention also comprises a kind of key of baffle type mechanical anti-theft lock.
Specifically: each marble hole is arranged in parallel, and vertical with lockhole place plane; In all pellet groups, the pellet stroke of a part of pellet group all identical, be a fixed range (A), the pellet stroke of another part pellet group also all identical, be another fixed range (B), and A is greater than B.When the quantity of this two parts pellet group respectively accounts for a half (when pellet group adds up to even number, as follows), maximum by the number of combinations of the pellet group of A or B distance moving, size of key is maximum; The hole that when key is laminar, the position of corresponding marble hole is opened pellet group sum half (or other quantity) at random in the above, pellet can pass through from its hole, and presses A distance moving.The pellet group that position of opening is not corresponding is because of the insertion rising B distance of key; During not perforate of key, can utilize " tartar " height difference above it to make the displacement of each pellet group be respectively A or B; The principle of unblanking is: when key is correct, in its hole of the slide plate of unblanking (10) in lock core, the pellet of (or adjacent) can not stop it to move, and can realize and unblanking.When key is incorrect, the pellet that at least has another kind of length in its hole of the slide plate of unblanking (10) stops it to move, and can not realize and unblanking; Key only inserts or extracts out, does not rotate, and the process of unblanking is that after insertion key, the action by other mechanism completes.
Lock core comprises a movably hole sealing plate (7), its in the process of unblanking marble hole footpath of transverse shifting distance (when lock core is designed to when cylindrical, hole sealing device just becomes tubular, and rotatable), all marble holes are sealed in centre, block the engagement and outreach between upper and lower pellet, and the movement of hole sealing plate (7) must carry out before the slide plate of unblanking (10) is mobile, this order is immutable.
Pellet group can be divided into more than 3 groups or 3 groups, and every group of pellet stroke is all identical, and adopts and not to be with hole key, its " tartar " highly to only have 3 or with 3 above level altitudes.Size of key increase because of its lockset, can reduce pellet group number and then simplified structure.
The unblank steel plate (11) of slide plate (10) and the top can be integrally combined structure, and in the process of unblanking together with holdout device along with below whole slip of contact surface of steel plate (9).
Hole sealing plate (7) and the slide plate of unblanking (10) one or the two all can reduce thickness and become laminar arm-tie, and it is only passing through when pulled between pellet, and the pellet in its hole is transverse shifting thereupon not.
Also can adopt a kind of one to wear the flat key of fin and the lockhole matching 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 longitudinal when adjacent its interlude become straight line.With laminar perforate key, compare, can reduce the associated components that pellet group is fallen, the move mode of pellet group is become by jack-up by whereabouts.
Below various piece function of the present invention and operating principle are elaborated:
1. key is rectangle thin slice (thickness 0.5mm, close with wallpaper blade, width 27mm, active length 32mm, total length 55mm, there is certain rigidity and toughness), first design, by 24 regularly arranged positions, is selected 12 position perforates at random in the above, the number of combinations in this half hole is 270.4 ten thousand (from probability angle, to consider, same total positional number, the number of combinations of opening half hole is maximum, and size of key is maximum.Be subject to the factor impacts such as overall dimension and processing capacity, total positional number is not suitable for choosing excessive).
Key piece is contained in 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 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 are wherein positioned at bottom are displaceable members, and its thickness is identical with the diameter of the steel ball in all marble holes, is 3mm.All the other 4 block plates maintain static.On every block plate, all have 24 marble holes, aperture 3.2mm, position is identical with key.After all steel plate stacks, can form 24 marble holes (under static state) that communicate up and down, hole depth 35mm.In each marble hole, pack altogether 7 pellets and 1 spring into, 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).Due to steel ball and cylinder-shaped marble pack order into by position of opening design on key piece, as shown in Figure 1, totally 12 groups of pellet group A (16), corresponding key piece have a hole site; Totally 12 groups of pellet group B (15), corresponding key piece without hole site, therefore after pellet group moves a certain distance by designing requirement, in hole sealing plate (7), be always steel ball, and highly concordant, therefore 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, therefore can move reciprocatingly; Another kind of situation is that key is incorrect, has at least a cylinder-shaped marble (all the other are steel ball) can stay in marble hole, and the slide plate (10) that makes to unblank can not move, unlatching and the locking principle of Here it is lockset of the present invention.
3. lockhole (5) is positioned at the upper surface of nethermost steel plate A (4), and shape is mated with key, is the narrow slit (high 0.6mm, wide 27.1mm) of a horizontal direction.Because pellet group packs into by vertical direction, therefore narrow slit makes various unlocking tools be difficult to play a role.Near lockhole of the present invention (5) and lockhole (5), there is no other small component, only steel ball possesses again anti-drilling function simultaneously, and ability of resisting destruction is strong.Lockhole entrance is designed to bell mouth shape, coordinates the oblique angle of key piece front end, is convenient to key and inserts.
This kind of lockhole, key structure and shape are the most obvious surface of the present invention and more crucial technology.
4. key only inserts or extracts out, does not rotate, and this is the most obvious method of operating and feature that the present invention is different from conventional lock.The process of unblanking is first to insert key, then relies on rotary handle an angle of 90 degrees to complete.Lockset is opened back handle and is automatically reset, then extracts key out.The process of specifically unblanking and principle are as follows:
The present invention is provided with a cam (24).Insert after key, by rotary handle band moving cam, rotate.Cam starts to rotate 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 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 lock core move down 2.4mm, and effect is to allow on key piece have the whole whereabouts 2.4mm of pellet group corresponding to hole site.On key piece, without hole site, the pellet group above it can not fall, contrary but because the insertion of key makes pellet group above it 0.5mm that rises overally.
2. no matter whether pellet falls, and all have all the time a steel ball, 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 in upper each marble hole of hole sealing plate (7).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 technical opening lockset is without possibility.This is key technology of the present invention, plays a key effect preventing aspect technical opening.
All pellets of the lockhole that (do not insert key) under static state top are the line of demarcation of each steel plate 0.6mm that all sinks relatively, is equivalent to 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 be take the numerical value such as 0.1mm, 0.2mm as differential preparation key decides displacement and the size of key obvious differences of pellet, are the basic features of the technology of the present invention, are also the main causes that can take sealing of hole mode simultaneously.
The slide plate of unblanking when 3. key is correct, in each hole of the slide plate (10) of unblanking after pellet has fallen, also all have a steel ball, and diameter of the steel ball is identical with the slide plate thickness of unblanking, highly concordant, therefore can move.In this case, by one, to push away spring (19) slide plate (10) that promotes to unblank mobile for fork C (20).When key is incorrect, under pellet group, fall behind, at least have 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 slide plate.
4. the slide plate (10) of unblanking is connected with a stoping block (18), and the two can level of synchronization move.When key is correct; stoping block (18) can be along with the slide plate of unblanking (10) be along protecting the soffit of beam (21) to move 4mm; 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 to complete to unblank.When key is incorrect, unblank slide plate and stoping block all can not move, and stop cam (24) to be rotated further, and can not open lockset.
Cam (24), in 50 degree angle rotation processes subsequently, can drive relevant transmission mechanism to complete follow-up unlocking action.
5. for preventing that powerful turning handle from causing lockset destroyed, between cam (24) and camshaft (27), be provided with collision bead (30) and the torsional moment protective device of protecting spring (31) to form.When torsional moment is excessive, collision bead (30) is lifted, camshaft (27) idle running, and lockset can not be opened.
6. the unblanking in process of rotatable handle an angle of 90 degrees, master latch and dead bolt are all pulled.After handle resets, master latch keeps transfixion, and dead bolt can eject under spring tension effect.If now close, visit (not doing other actions), dead bolt can lock door and only have dead bolt locking again.Due to the equal return of the slide plate of unblanking (10), hole sealing plate (7) and pellet supporting plate (3), therefore must could again open lockset with key outdoors.At Men Nei, can promote dead bolt pushes away and turns round (17) unlock deadbolt.
7., can under any circumstance by rotation swing handle (28), be realized and be unblanked or lock, the people that this function can prevent from being locked within doors can not open lockset.
8. the process of locking is outdoors without key, and reverse rotation handle 50 degree angles can complete, and then handle automatically resets.
9. for the specific function that key technology of the present invention utilizes the mobile aperture of hole sealing plate (7) distance, the marble hole that seals its top prevents technical opening lockset, also can realize and unblanking and the object 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 to delete, with steel plate D (11) topmost, substitute the slide plate (10) of unblanking, and it is upper that stoping block (18) is connected to steel plate D (11), every group of pellet reduces by 1 steel ball simultaneously.When key is correct, steel plate D (11) overlaps with the contact surface of each relevant pellet to the contact surface of below steel plate C (9), and steel plate D (11) can move horizontally and realize and unblanking by the upper surface along steel plate C (9) in the slideway of oneself.When key is incorrect, at least has a cylinder-shaped marble and stay on contact surface, stop steel plate D (11) mobile, 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 to 0.5mm simultaneously, become thin slice arm-tie (be 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.While unblanking, by cam, fork or other parts, pull thin slice arm-tie to move, and then drive stoping block (18) (or other types of devices) to move and complete 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 thin slice arm-tie and move), and the pellet of thin slice arm-tie top can be made a concession by against the force of the spring retraction, make thin slice arm-tie can be pulled and realize and unblanking.When thin slice arm-tie returns, the same external force that relies on pulls reset.
When key is incorrect, sealing of hole arm-tie is still removable, stays in the arm-tie hole of unblanking and to stop it to move, therefore can not open lockset but at least have a cylinder-shaped marble.
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 pellet.The type of drive of thin slice arm-tie is to be pulled, because of promote thin slice arm-tie move mode 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 of insertion lockhole is designed to 4 fins, be groove therebetween.The another side of key is plane.On every fin, be processed into wavyly, corresponding 6 positions of each crest, trough, design 24 positions on the key altogether, corresponding 24 marble holes above.The height of crest is identical (3mm, with respect to trough the lowest point height) all, and the trough degree of depth is consistent (trough bosom flushes with flute surfaces) all.Lockhole is positioned at the soffit of steel plate B (6) (thickness increase), and shape is mated with key.Each pellet group forms by 6 steel balls and 1 cylinder-shaped marble.The nethermost steel plate A of lock core (4) deletes, and it is upper that each pellet group all drops on pellet supporting plate (3), and pellet supporting plate (3) no longer moves up and down, and is but fixed on lock body on the contrary, plays and supports and position-limiting action.After this kind of key inserts, the 1mm that all raises of the pellet height in trough, the 4mm that all raises of the pellet in crest, and the pellet group number on crest is 12 (this kind of situation is that crest, wave trough position are determined at random because number of combinations is maximum equally).Now in hole sealing plate (7) hole, be steel ball and highly concordant, removable.When key is correct, the slide plate of unblanking (10) is also steel ball and highly concordant, removable in hole, therefore can open lockset.When key is incorrect, hole sealing plate (7) is still removable, but in the slide plate of unblanking (10) hole, has 1 cylinder-shaped marble at least and can not move, and can not open lockset.
Spring in each pellet group should not surpass following distance from static state in theory to the limit travel being compacted: unblank after the pushing to Kong Zhongyi of slide plate (10) of all pellets does not have cylinder-shaped marble, and the slide plate of unblanking is removable, can not anti-theft unlocking tool.Now the displacement of pellet is the limit travel of marble spring.
This programme calculates according to the thickness of steel plate C (9) (9mm), cylinder-shaped marble length (6mm) and lockhole size, and the limit travel of spring reaches for 10mm.But physical length is only 9mm under spring static state, 4mm after compacting, range 5mm,, therefore there is not above-mentioned situation in impulse stroke 4mm.
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; Rotatable handle angle reduces by approximately 10 degree angles, and 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 there being the effect of hole sealing plate (7), the function of anti-technical opening is still effective generally.So must be used in conjunction with the function of hole sealing plate while adopting this scheme, otherwise anti-technical opening ability significantly reduces.
4. assembled scheme, is about to above-mentioned each scheme Integrated using.
10. only otherwise remembered by despiteful people, lockset of the present invention just can antitheft in the position of keyhole.User can be recorded in shelter by lockhole position, in order to the use of preparation key.As key loss, also can reselect position of opening, configure new key, and reload each pellet group (those possessing an ordinary skill in the pertinent arts all can operate), do not need to change a complete set of lockset.
11. for improving anti-damage ability, especially for the Zuan Ge hole, appropriate location of the outside steel plate at lock body (1), recycle the situation that certain instrument is stirred associated components in lock and then opened lockset, can be in lock body, near the locus of outside steel plate, pack 3～5 Thin Rectangular steel discs 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 diameter in aperture.1 rectangular opening assembles with protection beam (21), the length in hole, the large 1～3mm of the same comparable protection beam cross dimensions of width.
The stalloy not being secured in a press being superimposed has stronger anti-drilling function.The now corresponding adjustment of front end one side size of hole sealing plate (7), the slide plate of unblanking (10) (can not adjust yet, by the dimension modifying of Thin Rectangular steel disc, be: long 72mm * high 105mm, protected area reduces).
Invention effect
1. lockhole of the present invention is a narrow slit, and space is very narrow, makes various unlocking tools be difficult to play a role.Simultaneously near lockhole and lockhole, there is no other small component except steel ball, the survivability such as anti-drilling is strong.
2. hole sealing plate of the present invention (7) moves an aperture distance, seals the marble hole of top, and unlocking tool has also lost effect, and this technology makes theftproof lock of the present invention have reliable anti-technical opening performance.
3. the actual available key amount of lockset of the present invention is identical with theoretical value.
4. the process operation of locking, unblank of the present invention is simple, widely applicable in various age bracket crowds.
5. key of the present invention changes position of opening and again prepares after key, can ressemble a whole set of lockset.
6. each component of the present invention are easy to processing and manufacturing, and stamping parts is more, and cost is low, are applicable to batch production.
7. lockset of the present invention, to environment no requirement (NR), can be used on above various security doors, safety cabinet, national treasury etc.

The specific embodiment
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, describe concrete structure and the operating principle of the baffle type mechanical anti-theft lock that the present invention proposes in detail.
1. lock box (1) is made by steel plate, before the thick 5mm of steel plate, after (an indoor side) thick 4mm of steel plate, the thick 3mm of surrounding steel plate.
2. key is rectangle thin slice, thickness 0.5mm, and width 27mm, active length 32mm, total length 55mm, superincumbent working region is first designed by 24 regularly arranged positions, selects at random 12 position perforates, aperture 3.2mm.Laterally totally 6 arrange, pitch-row 6.4mm, adjacent two hole back gauges are 3.2mm.Longitudinally (lockhole depth direction) 4 arranged totally, pitch-row 5.2mm, and adjacent two hole back gauges are 2mm.Key piece is contained in protective sleeve, and the side of protective sleeve has slotted hole, in-built key button, and key button is fixedly connected with key piece, and contacts with steel wire, and hand push key button can make key piece eject or spring into.Consider the clearance issues of key piece and lockhole (5), the aperture of the key piece of actual processing is 3.3mm, but pitch-row is constant.
3. lock core is by steel plate A (4), steel plate B (6), hole sealing plate (7), steel plate C (9), the slide plate of unblanking (10) and steel plate D (11) totally 6 parallel being formed by stacking of steel plate, wherein be positioned at below hole sealing plate (7) and be positioned at above the slide plate of unblanking (10) be displaceable member, its thickness is identical with all diameter of the steel ball, is 3mm.In addition, return spring (8) has all been installed in the left side of hole sealing plate (7) and the slide plate of unblanking (10), the equal limited location pin in two ends.All the other 4 block plates are fixed on lock box (1).On every block plate, all have identically with key by 24 regularly arranged marble holes, aperture is 3.2mm.After all steel plate stacks, can form 24 marble holes (under static state) that communicate up and down, hole depth 35mm.In each marble hole, pack altogether 7 pellets and 1 spring into, 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).Steel ball and cylinder-shaped marble pack order into as shown in Figure 1, wherein pellet group A (16) is totally 12 groups, corresponding key piece have a hole site; Totally 12 groups of pellet group B (15), corresponding key piece without hole site.
When change pellet group A (16) or pellet group B (15) pack position into time, more corresponding change key position of opening can form another set of lockset, therefore lockset of the present invention can be ressembled when needed, need not a complete set ofly change.
4. lockhole (5) is positioned at the upper surface of nethermost steel plate A (4), and shape is mated with key, is the narrow slit of a horizontal direction, high 0.6mm, wide 27.1mm.Lockhole entrance is designed to bell mouth shape, is convenient to key and inserts.
5. lower carriage (2) is positioned at steel plate A (4) below, plays and supports and position-limiting action.There is opening on its right side, is convenient to assembling and the swing of fork A (34).Pellet supporting plate (3) is placed in lower carriage (2), can vertically move up and down, and stroke is 2.4mm, and when pellet supporting plate (3) falls, the dropping distance of pellet group is also 2.4mm.Under static state, pellet supporting plate (3) is passed through fork A (34) jack-up by top spring (35).
6. key of the present invention only inserts or extracts, and does not rotate.The process of unblanking is first to insert key, and then rotary handle an angle of 90 degrees can complete.Lockset is opened back handle and is automatically reset, and extracts key out, completes the overall process of unblanking.The principle of specifically unblanking is as follows:
1. insert after key, by rotary handle band moving cam (24), rotate.Cam (24) starts to rotate 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, has the whole whereabouts 2.4mm of pellet group corresponding to hole site on key piece.On key piece, without hole site, the pellet group above it can not fall, on the contrary, and 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 technical opening lockset is without possibility.This is key technology of the present invention, plays a key effect preventing on technical opening.
The slide plate of unblanking (10) when 3. key is correct, in each hole of the slide plate (10) of unblanking after pellet has fallen, also all have a steel ball, and diameter of the steel ball is identical with the slide plate thickness of unblanking, highly concordant, therefore 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, under pellet group, fall behind, 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 driving lever (22), locking bolt arm-tie (13) and dead bolt arm-tie (12) to move to unblank.When key is incorrect, the slide plate of unblanking (10) all can not move with stoping block (18), stops cam (24) to be rotated further, and can not open lockset.
7. in a lateral location of cam (24), be equipped with and stir pin (23), when cam turns to design attitude, by stirring pin (23), promote driving lever (22) swing, and then make the mobile 30mm of locking bolt arm-tie (13) and complete corresponding unlatching of locking point.In addition, when stirring the final stage of pin (23) in cam rotation, also can promote the mobile 12mm of dead bolt arm-tie (12), complete 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. the unblanking in process of rotatable handle an angle of 90 degrees, master latch and dead bolt are all pulled.After handle resets, master latch keeps transfixion, and dead bolt can eject under spring tension effect.When closing, only have behind the door bolt lock regularly, because the equal return of the slide plate of unblanking (10), hole sealing plate (7) and pellet supporting plate (3), therefore must could again open lockset with key outdoors.
10. swing handle (28) is fixed on 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), complete and lock within doors or unblank.Because the bidirectional swinging of driving lever (22) is all without hindrance, therefore can under any circumstance be realized and be unblanked or lock by rotation swing handle (28) in door, the people that this function can prevent from being locked within doors can not open lockset.
Between 11. cams (24) and camshaft (27), be provided with the torsional moment protective device that collision bead (30) and protection spring (31) form.When torsional moment is excessive, collision bead (30) is 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 after cam (cross dimensions 6mm * 6mm) in formed square opening and can place collision bead (30) and protect spring (31).
Another position of 12. cams (24) is equipped with latch-locking (25).Because after handle resets, rotating backward 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 promotes locking bolt arm-tie (13) oppositely mobile (30mm) and realize and locking, and handle automatically resets afterwards.
13. reset tension springs (26) rely on its pulling force of two points up and down to cam (24), can make to automatically reset after handle rotation.
14. for the specific function that key technology of the present invention utilizes the mobile aperture of hole sealing plate (7) distance, the marble hole that seals its top prevents technical opening lockset, can use other several alternative structure:
1. this scheme key is constant.With steel plate D (11) topmost, substitute the slide plate (10) of unblanking, and it is upper that stoping block (18) is connected to steel plate D (11), every group of pellet reduces by 1 steel ball simultaneously.When key is correct, steel plate D (11) overlaps with the contact surface of each relevant pellet to the contact surface of below steel plate C (9), and steel plate D (11) and stoping block (18) can move horizontally and realize and unblanking in the slideway of oneself.When key is incorrect, at least has a cylinder-shaped marble and stay on contact surface, stop steel plate D (11) mobile, 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 to 0.5mm simultaneously, thereby becoming 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.While unblanking, by cam, fork and other parts, pull thin slice arm-tie to move, and then drive stoping block (or other types of devices) to move and complete 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 thin slice arm-tie and move), and the pellet of thin slice arm-tie top can be made a concession by against the force of the spring retraction, therefore thin slice arm-tie can be pulled and realize and unblanking.When thin slice arm-tie returns, the same external force that relies on pulls reset.
When key is incorrect, sealing of hole arm-tie is still removable, stays in the arm-tie hole of unblanking and to stop it to move, therefore can not open lockset but at least have a cylinder-shaped marble.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 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 of insertion lockhole is designed to 4 fins, be groove therebetween.The another side of key is plane.On every fin, be processed into wavyly, corresponding 6 positions of each crest, trough, design 24 positions on the key altogether, corresponding 24 marble holes above.The height of crest is identical (3mm, 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 it is upper that each pellet group all drops on pellet supporting plate (3), and pellet supporting plate (3) no longer moves up and down, and is but fixed on lock body on the contrary, plays and supports and position-limiting action.Downside at steel plate B (6) (enlarged in thickness) has the lockhole matching with key.After this kind of key inserts, the 1mm that all raises of the pellet height in trough.Pellet in the crest 4mm that all raises, and the pellet group number on crest is 12.Now in hole sealing plate (7) hole, be steel ball and highly concordant, removable.When key is correct, the slide plate of unblanking (10) is also steel ball and highly concordant, removable in hole, therefore can open lockset.When key is incorrect, in the slide plate of unblanking (10) hole, has 1 cylinder-shaped marble at least and can not move, can not open lockset.
In this programme, the thickness (9mm) of steel plate C (9), cylinder-shaped marble length (6mm), length 9mm under pellet group medi-spring static state, impulse stroke 4mm, range 5mm after compacting, limit travel 10mm, can not open lockset by the method that pellet is all pushed to.
15. for improving anti-damage ability, and the locus near outside steel plate in lock body packs 4 Thin Rectangular steel discs into, and it is of a size of:
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 not being secured in a press being superimposed has stronger anti-drilling function.
16, camshaft (27), the upper assembling of fork axle (32) pad, in order to regulate gap spacing.
17, utilize moving back and forth of locking bolt arm-tie (13), its right-hand member can extend and be connected to drive to be locked on the transmission mechanism of a unlatching and locking up and down, thereby realizes multi-point fastening.
Note: " highly the flushing " in literary composition, refers to the pellet height and position situation falling 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 low 0.1mm of the corresponding upper surface of steel plate of pellet aspect ratio, but do not affect the operational effect of each associated components, therefore also claim " highly flushing ".
