Abstract

The invention relates to an inserted core lock for a door, in particular to an inserted core idle lock. A technology of overlapping an upper lock core and a lower lock core and a lock marble with a groove are utilized, a method for clamping a mobile fork with a marble groove into an upper notch of the lock marble with the groove is longitudinally utilized, and the technical scheme that a V-shaped groove or a curved annular groove are formed in the lower lock core to push the mobile fork is adopted, so that the tail part of the upper lock core is combined with the contact surface of a rotation propeller embedded in the lower lock core hole groove to meet the condition that a movable key shaft is driven to be embedded with the lower lock core and a back lock core in a lock tongue while the upper lock core and the lower lock core are relatively rotated so as to fulfill the aim of unlocking; and when the lock is opened in a violence mode, the mobile fork cannot move because the notch in the lock marble with the groove between the upper lock core and the lower lock is not on the same straight line, so that the upper lock core and the lower lock cannot be relatively rotated, and the rotation propeller cannot be shifted; and moreover, the movable key shaft cannot be rotated along with the lower lock core because the movable key shaft cannot be clamped into the lower lock core; and therefore, the idle phenomenon that the lock core rotates and the lock tongue does not rotate occurs.

Description

A kind of lock pin idle running lock

Technical field:

The present invention relates to a kind of door furniture lockset, particularly a kind of lock pin idle running lock of security door use.

Background technology:

What present door lock (lock pin lock) generally used all is common lock pin lock; Its antitheft theory mainly reaches by the direction of motion (like snake-shaped blade lock core, unsteady pellet shot from a slingshot) that increases marble amount and change pellet shot from a slingshot; Also have some to reach by increasing the moving tooth difficulty in addition, like inside and outside pellet shot from a slingshot, oblique pellet shot from a slingshot, band groove pellet shot from a slingshot etc., these technological appearance have increased much the difficulty of skilled unlocking really; But it then is powerless using hard violence unlocking tool in the face of the thief; Many locksets are all opened by violent tool like this, because the thief can not spend a lot of times to remove to do technical opening, what they were particular about is quick, simple and direct.To this situation, first generation idle running lock has appearred in the market, and the anti-technical unlocking of this idle running lock and anti-violence are opened and have all been reached good effect.For example at " a kind of idle-run spring lock " of on September 30th, 2007 application, the patent No. is 200710035852.4 invention, this disclosure of the Invention a kind of idle-run spring lock; Lock core and rear lock core before comprising, and preceding lock core the locking side column groove vertically is set, this deckle post or the like is set in the locking side column groove simultaneously; This lockset design is more reasonable; Meet mechanically operated method, we can know when key inserts from motion, and the groove on the pellet shot from a slingshot just in time aligns with the locking side column groove; At this moment under the pressure reduction of both sides spring; The spring that elastic force is big pushes the pellet shot from a slingshot breach side bumper piece on the locking side column groove on the pellet shot from a slingshot and produces displacement, and the locking side column groove before the sliding pin on the rear lock core snaps in along chute on the lock core becomes one it, and key just can drive rear lock core and unblank; Key counter-rotating during locking is when rear lock core meets obstructions (the restriction breach that is rear lock core here), because an inclined-plane (also can on the chute mouth of rear lock core) is arranged on the sliding pin; This inclined-plane is by the locking side column groove roof pressure of preceding lock core; Make its top pressure spring and retreat, chute is pushed up back original position when retreating into the key return, (slightly to surpass certain angle), and locking side column return under the little spring promotion of elastic force; Groove on it is just in time corresponding with the lock pellet shot from a slingshot, and the lock pellet shot from a slingshot can return when key is extracted.Can find out that from above-mentioned operating principle the pressure reduction of spring requires very highly during its work, and spring is all very tiny; Locking side column is to lean on tiny spring to promote, and all can stop the locking side column motion as tiny dust, the sticking entering lock cores of transferring such as greasy dirt etc., so this is to cause the malfunctioning first cause of not opening of idle running lock at present; This kind lock can only be on the unidirectional inclined-plane that has in addition; Only turn at one and work, its working range can only be in a circle, oppositely can only be unloaded; Otherwise the meeting locking, so be not suitable for door lock (because door lock will rotate more than two circles and load is arranged).Above this patent of invention described be that locking side column is axially-movable, also having the invention of several similar approach in addition also mainly is this principle of utilization, its function is consistent with above-mentioned patent.The know-why that equally also has some idle running to lock is utilized locking side column, and radial motion makes it produce displacement and drives the dead bolt rotation along the axle center; They are to utilize the pellet shot from a slingshot or the blade of band V-arrangement skewed slot when key promotes, to produce displacement; When all pellets shot from a slingshot or the V-arrangement skewed slot all align on the blade during at straight line; Locking side column just can snap in v-depression and form displacement under very tiny spring compressing; The middle ring that connects dead bolt so just can be connected as a single entity because of moving in the locking side column with lock core, thereby key just can be opened lockset.This kind lockset is owing to be to lean on the lock core spring to push pellet shot from a slingshot to make its inclined-plane with locking side column jack-up, so the lock core spring can not be too thin, too thin then pushes up motionless locking side column; Too hard then key plug is difficulty very all; Simultaneously the stage clip on the locking side column can not be too hard, too hard pellet shot from a slingshot then push up motionless it, too soft words have locking side column such as some greasy dirts just not come out on the top; We do common lockset and existing idle running lockset once relatively finding out; Common lockset is that the power of utilizing key to insert pushes pellet shot from a slingshot, and this power can be very big, so the lockset reliable operation.The idle running lock of prior art then is after key inserts, after being conformed to according to profile of tooth by spring for the second time, to produce thrust again to promote conditions such as locking side column; The size of thrust has nothing to do with the size that hand is exerted oneself so for the second time; But depend on the pressure of spring or even the pressure differential between the spring; Its thrust is difficult to guarantee (present in addition idle running lock inner components is many, part is too little, complex structure, transmission progression many) with regard to the influence that receives a lot of resistance factors like this; So malfunctioning rate height is locked in present idle running, the fault rate height has not just been minded yet.

I am at " a kind of idle-run lock head of axial advance " of application on November 25th, 2008; Application number is 200810203300.4; This disclosure of the Invention a kind of use the lock pin idle-run lock head, this idle running lock has used the trough of belt pellet shot from a slingshot all to be put in place on the top by key, when the groove between wherein is straight line; Thereby be stuck in the pushing ram that the slide plate that has pellet shot from a slingshot hole groove between pellet shot from a slingshot just can travel forward through the groove on the pellet shot from a slingshot front end and snap in dead bolt, screw key drives dead bolt again and rotates and accomplish and unblank then.Can know from the technical scheme of this patent, the control knob when unblanking on the screw key handle or directly push control knob and push axial push rod again with finger, axially push rod advances dead bolt through the buffering stage clip with pushing ram again; At this moment screw key just can drive pushing ram and together rotates and lock is opened; Otherwise, if key not to only can cause on the pellet shot from a slingshot groove and the groove on the slide plate not point-blank, just slide plate can not be pushed because of the groove that can't snap on the pellet shot from a slingshot like this; Extrapolability just can be cushioned stage clip and absorb; So pushing ram can not be pushed into dead bolt, lock also just can't be opened, but at this moment key still can rotate.Though not going out the heart in design, this lockset carries; Reached the requirement of idle running lock; But its shortcoming is to use inconvenience; Particularly also need to rotate control knob or push control knob with hand, especially incompatibility old man and child use because people's common practice insert the direct the sort of custom that just can unblank of key." a kind of device of the lock that dallies " that I applied for again on November 28th, 2008; Application number is 200810202868.4; This disclosure of the Invention a kind of very simple idle running lock, this technology can only need to increase several parts with various common locks on the basis that does not change original structure just can upgrade to the idle running lock, the appearance of this technology can increase substantially the anti-stubborn sled function of present various theftproof locks; Though it can use on doors such as common safe-guard door lock, villa door lock; But because of volume is difficult to be applied on the mortise door lock greatly, because the space of lock pin lock is limited, and three layers on middle level also have inner core,, shell locked in the common idle running of this idle running picture lock; And between lock ring and shell, must install damping unit additional, so should technology be difficult to be applied on the mortise door lock.

Summary of the invention:

The objective of the invention is to release a kind of idle-run lock pin that can be applied on the mortise door lock; It has been used upper and lower one group of lock core and when key conforms to, can rotate each other and drive miscellaneous part and produce a kind of new technology than the great displacement; It is except can be as the normal unlatching of common door lock; Can also receive twist the sled violence when opening lock core can with violent tool with then lock but can not be opened; It can well defend to prize at present the special criminal trend that adopts the violence picking lock of deathwatch thief, plays an important role for protecting the people and national wealth safety.

Vertically have on the said upper lock core 2 and move fork pockets or shift fork hole slot; Lock spring 21 and trough of belt lock pellet shot from a slingshot (or trough of belt lock blade) 16 (seeing Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14) are housed in the pellet shot from a slingshot hole radially; Wherein Figure 11, Figure 12 are atom lock core type; Figure 13, Figure 14 are trough of belt lock blade; Have through hole (form of structure that has also has straight trough in through hole) in the middle of the following lock core 6 and have the keyway 20 (seeing Fig. 2, Figure 15, shown in Figure 16) that supplies draw key axle 10 to snap in dead bolt 11 contact positions; Following lock core 6 has V-arrangement or arc groove (as shown in Figure 7) with the end face contact position of upper lock core 2; Perhaps descend lock core 6 near having curve annular groove (seeing Figure 15, Figure 16) on circle or the cylindrical in upper lock core 2 ends; Have on the shift fork 3 pellet shot from a slingshot groove and active card upper lock core 2 vertically move in the groove or the shift fork hole slot in (seeing Fig. 1, Fig. 6, Fig. 7, Figure 11, Figure 12); Shift fork 3 offsets (seeing Figure 11, shown in Figure 13) through spring 4 and V-arrangement or circular groove on the following lock core 6 or directly and the curve annular groove on the following lock core 6 be nested (seeing Figure 15, Figure 16); Offseting through spring 4 is to consider behind return, can shift fork 3 be compressed into v-depression (seeing shown in Figure 17), and direct and curve annular groove is nested and then can saves spring 4, because the shift fork 3 that is stuck in the curve annular groove can be driven displacement back and forth by cell wall; Come pivot bush unit through pin, annular groove or snap ring, annular groove or pin, groove between upper lock core 2 and the following lock core 6, the upper left corner among Figure 11 is the socket mode of pin, annular groove, and other types are omitted.This section technical characterictic mainly is following several sections, the one, and upper lock core 2 parts, every have trough of belt to lock can implementing of lock cylinder, can be as the lock core part in the present embodiment like snakelike tank lock core, interior external-compression type atomic lock core, blade lock core etc.; The 2nd, the needs that have in the intermediate throughholes of following lock core 6 have straight trough (if any rotatable propeller 8 and rotatable propeller 8 be to do in relative rotation with upper lock core 2 afterbodys); (like draw key axle 10 is directly to flexibly connect through connector 17 and shift fork 3 and descend the straight trough of need not opening that has in the intermediate throughholes of lock core 6; Or there is not rotatable propeller 8 in the structure; Or rotatable propeller 8 is done in relative rotation with following lock core 6 again through non-circular cylinder cover card and rotatable propeller 8 with upper lock core 2 afterbodys), all given explanation in the specific embodiment; The 3rd, the v-depression on shift fork 3 and the following lock core 6 offsets, and this structure is to push shift fork 3 towards a direction motion through the inclined-plane that makes on the V-type groove that relatively rotates between upper lock core 2 and the following lock core 6, and backhaul is then accomplished by spring 4; When shift fork 3 employings are stuck in down in the curve annular groove on the lock core 6; The end face of annular groove two sides can advance shift fork 3 towards two direction motions; Thereby can omit spring 4; Also having a kind of is that shift fork 3 adopts the form of colluding to be stuck in down on the reverse cam surface of lock core 6 in the image pattern 18, and this is the bad technology of a kind of change, need not as far as possible; The 4th, the pivot bush unit between upper lock core 2 and the following lock core 6, the general method of pin and annular groove that adopts is relatively good, because snap ring, annular groove must be relevant with shell 7, can increase many frictional force like this, to being unblanked to make troubles; And the combination of locked groove relatively is fit to common lockset, because be monolateral stressed.This section adopted technical purpose that above-mentioned technological means mainly reaches in the lock core of upper and lower stack through trough of belt upper lock core 2 in lock coincideing of tartar on pellet shot from a slingshot 16 and the key 1 make upper lock core 2 can and following lock core 6 between the rotation (about 90 ° of this Rios) of a relative angle can be arranged; And when the groove on the tartar of key 1 and the trough of belt lock pellet shot from a slingshot does not match (when violence is opened), can not relatively rotate because of stopping just of shift fork 3 between upper lock core 2 and the following lock core 6.

Two contact surfaces of the afterbody of said upper lock core 2 and rotatable propeller 8 be one group complementary and one of them have the concavo-convex body (like Fig. 1, Figure 13, shown in Figure 15) on inclined-plane; Because the object of two concavo-convex complementations can also can separate because of the top is opposing mutually when relatively rotating because of concavo-convex mutual embedding snaps in when relatively rotating simultaneously; Perhaps two contact surfaces of the afterbody of upper lock core 2 and rotatable propeller 8 are one group and can inhale the magnet 19 (as shown in Figure 3) of scolding mutually, because in the arrangement of N, the S utmost point, can make adhesive and repulsion each other between the two through one group of magnet 19 through changing polarity; Perhaps two contact surfaces of the afterbody of upper lock core 2 and rotatable propeller 8 are one group of helicoid (like Figure 19, shown in Figure 20); Through relatively rotating between upper lock core 2 and the following lock core 6, the screw rod 22 that is fixed on upper lock core 2 afterbodys just drives the rotatable propeller 8 of inlay card in following lock core 6 hole slots and just can move forward and backward; Perhaps two contact surfaces of the afterbody of upper lock core 2 and rotatable propeller 8 are curve annular groove and pin (shown in figure 21), and pin promotion rotatable propeller 8 when rotating that rotation upper lock core 2 just can make its tail end be stuck in the rotatable propeller 8 hole inner curve annular grooves is done axial displacement in the hole slot of following lock core 6; Rotatable propeller 8 active card are embedded in down in the hole slot of lock core 6.This section technical scheme all is that upper lock core 2 makes rotatable propeller 8 in the hole slot of following lock core 6, do axial displacement through the arbitrary scheme in four above-mentioned technical schemes in rotation; Have in the hole slot of lock core 6 down in this programme and supply the straight trough that rotatable propeller 8 can only axially-movable; Rotatable propeller 8 is pressed in the just displacement back and forth in dead bolt 11 of draw key axle 10 on the rotatable propeller 8 by stage clip 9 when axially moving, distinguish and can distinguish embeddings mutually with following lock core 6 and the keyway 20 on the rear lock core 13 thereby can reach draw key axle 10.

The hole of said down lock core 6 inboard with rotatable propeller 8 contact end face be one group of complementation and one of them have the concavo-convex body (shown in figure 22) on inclined-plane; Perhaps descend the inboard contact surface in hole of lock core 6 to be one group and can inhale the magnet 19 of scolding mutually with rotatable propeller 8; Perhaps descending the inboard contact surface with rotatable propeller 8 in hole of lock core 6 is one group of helicoid; Perhaps descending the inboard contact surface with rotatable propeller 8 in hole of lock core 6 is curve annular groove and pin (shown in figure 23); Rotatable propeller 8 is actively set on the non-circular cylinder of upper lock core 2 afterbodys.This section four technical schemes and top technical scheme have just in time been changed individual part; Both originally, changed non-circular cylinder moving linearly at present, and that is to say and be originally that making rotatable propeller 8 in relative rotation with upper lock core 2 afterbodys changes in the circular hole with following lock core 6 at present and relatively rotating along upper lock core 2 afterbodys along the rotatable propeller 8 of lock core 6 hole slot moving linearlies down; This technical pattern with the technical pattern of epimere and this section is different to be caused; But its final result is the same with purpose; Exactly through relatively rotating and make inlay card do axially-movable along lock core between upper lock core 2 and the following lock core 6, be close to rotatable propeller 8 and do axially-movable thereby can drive draw key axle 10 at the rotatable propeller 8 in the following lock core 6 through the arbitrary scheme in above-mentioned four schemes.

The afterbody of said upper lock core 2 is enclosed within down in the intermediate throughholes of lock core 6 and at afterbody and following lock core 6 afterbodys and forms conplane end face; Upper lock core 2 or down lock core 6 have v-depression or A shape raised line on the plane having at least on the same plane of afterbody, on the end face of draw key axle 10 and this plane contact the bar shaped raised line or a groove (like Fig. 4, Figure 24, shown in Figure 25) that can snap in above-mentioned plane groove or raised line is arranged; Perhaps have groove or raised line on upper lock core 2 and the following lock core 6 rear-end conplane end faces, on the end face of draw key axle 10 and this plane contact the A shape raised line or a v-depression that can snap in above-mentioned plane groove or raised line is arranged; Above-mentioned two kinds of schemes are that groove and raised line are carried out the technology replacement; In fact no matter which face is groove or raised line; As long as a groove or raised line are wherein arranged is V-arrangement or A shape raised line; So just can make upper lock core 2 and following lock core 6 when rotating, rely on the inclined-plane of V-arrangement or A shape that another concavo-convex body is ejected, thereby make draw key axle 10 when upper lock core 2 and following lock core 6 are relatively rotating, rely on this technical scheme of tail end that it is moved axially in the hole slot of dead bolt 11; The groove that has separately on upper lock core 2 and the following lock core 6 rear-end planar ends just can form a complete plane (like Figure 24, Figure 25, Figure 26, shown in Figure 27) that does not have breach when intersecting (or near vertical) position; The raised line that perhaps is provided with separately on upper lock core 2 and the following lock core 6 rear-end planar ends can form a plane (like Figure 26, shown in Figure 27) when intersecting (or near vertical) position; As can be seen from Figure 4; Inside and outside all have groove on the planar end of the upper lock core that is nested 2 and following lock core 6; Wherein have V-shaped groove on the upper lock core 2 (circle promptly); When the groove on the inside and outside circle intersects (like Figure 26, shown in Figure 27); Because of the projection on the V-shaped groove limit on the upper lock core 2 has just in time remedied the sunk part of time lock core 6 upper grooves, so this moment, whole plane became a complete plane that does not have breach, the raised line on the draw key axle 10 also just can't snap in this plane of being made up of inside and outside circle (although above fluted); Draw key axle 10 also just can't produce displacement; When its groove mouth all overlaps after the groove on the inside and outside circle is rotating to an angle (like Figure 28, shown in Figure 29); At this moment see from the groove side that whole plane overlaps inside and outside a groove is arranged; At this moment the raised line on the draw key axle 10 also just can snap in this groove and be subjected to displacement under the promotion of stage clip 9, thus play with draw key axle 10 by the keyway 20 on original and the rear lock core 13 mutually embedding then become and following lock core 6 on keyway 20 mutual embeddings.This section best of breed is that the afterbody of upper lock core 2 has v-depression, and the afterbody of following lock core 6 has square groove, and the contact end face of draw key axle 10 is provided with bar shaped rectangle raised line.This section technical scheme is different with the technical scheme of front, and this scheme has been saved rotatable propeller 8, can make the length of lock core do forr a short time; This section technical purpose is identical with the purpose of several sections of fronts; All be through relatively rotating between upper lock core 2 and the following lock core 6 and drive draw key axle 10 moving axially in dead bolt 11, thereby reach the purpose of unblanking through the arbitrary scheme in the above-mentioned several kinds of technical schemes.

Most preferred embodiment one of the present invention sees for details as follows: as shown in Figure 1; Said lock pin idle running lock mainly is made up of key 1, upper lock core 2, following lock core 6, shell 7, draw key axle 10, dead bolt 11, rear lock core 13, lock pellet shot from a slingshot 14, snap ring 15, lock spring 21; Upper lock core 2 is movably arranged in the preceding lockhole of shell 7 with following lock core 6; Rear lock core 13 is movably arranged in the back lockhole of shell 7; Lock pellet shot from a slingshot 14 is housed in the rear lock core 13; Be provided with draw key axle 10 in the hole slot of dead bolt 11 and itself be installed in down lock core 6 and rear lock core 13 between; Snap ring 15 is stuck in that (or on upper lock core 2) is characterized in that on the rear lock core 13 upper and lower lock cores 6: preceding lock core is by upper lock core 2, lock core 6, shift fork 3, trough of belt lock pellet shot from a slingshot 16 and lock spring 21 constitute down, and draw key axle 10 contacts with rotatable propeller 8 in being embedded in down lock core 6 hole slots through stage clip 9 or one group of same sex magnet 19, and rotatable propeller 8 contacts with the afterbody of upper lock core 2; Damping unit 12 is installed on the dead bolt 11, has on the end face of following lock core 6 or the periphery and damping unit 12 corresponding damping holes; Vertically have on the said upper lock core 2 and move fork pockets or shift fork hole slot; Lock spring 21 and trough of belt lock pellet shot from a slingshot 16 (or trough of belt lock blade) (like Figure 13, shown in Figure 14) are housed in the pellet shot from a slingshot hole radially, also can select crescent lock core (being commonly called as the gold-idea lock core) (like Figure 11, shown in Figure 12) for use; Have through hole in the middle of the following lock core 6 and have the keyway 20 that supplies draw key axle 10 to snap in dead bolt 11 contact positions; The end face contact position of following lock core 6 and upper lock core 2 has the groove of V-arrangement or circular arc; Have on the shift fork 3 pellet shot from a slingshot groove and active card upper lock core 2 vertically move in the fork pockets or the shift fork hole slot in; Shift fork 3 offsets through the v-depression on spring 4 and the following lock core 6; Come pivot bush unit (like Figure 11, Figure 18, Figure 24, shown in Figure 25) through pin, annular groove between upper lock core 2 and the following lock core 6; Shift fork block 5 promptly snaps in upper lock core 2 and combines together with upper lock core 2 in the present embodiment after shift fork 3 is packed into, so can be regarded as upper lock core 2 (embodiment that has can remove shift fork block 5); Two contact surfaces of the afterbody of said upper lock core 2 and rotatable propeller 8 are one group of complementary concavo-convex body that has the inclined-plane (can need only one of them part and have the inclined-plane); Here the afterbody that is upper lock core 2 is a clinohedral), rotatable propeller 8 active card are embedded in down the hole slot interior (the hole slot here is to have straight trough in the hole) of lock core 6.During operate as normal; Insert first wife's key 1; Notch on all troughs of belt lock pellets shot from a slingshot 16 just can be lined up a straight trough (like Fig. 8, Fig. 9, shown in Figure 10), just key 1 its upper lock core 2 can and then rotate because the damping hole on the lock core 6 is stuck on the pellet shot from a slingshot of damping unit 12 down; Following lock core 6 just can not rotate; And the rotation of upper lock core 2 will make the V-arrangement end face that is stuck in lock core 6 end faces under shift fork 3 edges of moving in the fork pockets move, and when moving to the V-shaped groove inclined-plane, shift fork 3 just can move fork pockets in V-arrangement pushed lower edge and do axial displacement; And the pellet shot from a slingshot groove mouth block on the shift fork 3 is just in time corresponding with the breach on the trough of belt lock pellet shot from a slingshot 16; Shift fork 3 is at the notch that when the V-shaped groove inclined-plane moves, just can snap in gradually on the trough of belt lock pellet shot from a slingshot 16 with not stopping like this, upper lock core 2 forward to motionless till (promptly running into alignment pin), at this moment upper lock core 2 and following lock core 6 just turn over maximum angle (90 °); In the relatively rotating of upper lock core 2 and following lock core 6, can find out that from Figure 30 upper lock core 2 afterbodys and rotatable propeller 8 also change at occurrence positions; Before upper lock core 2 does not rotate; The concave surface of rotatable propeller 8 does not snap in the convex surface (at this moment these two male and fomale(M&F)s are 90 ° of intersection location states) of the afterbody of upper lock core 2; Also keyway 20 embedding mutually on the left side and the rear lock core 13 of key above the draw key axle 10 is rotated rear lock core 13 this moment and just can be driven dead bolts 11 with commentaries on classics through draw key axle 10; After upper lock core 2 rotates about 90 ° (shown in figure 31); The convex surface of upper lock core 2 tail ends is also with changeing; And be embedded in down in lock core 6 hole slots rotatable propeller 8 because of following lock core 6 is blocked by damping unit 12 can not be with changeing, the convex surface of upper lock core 2 tail ends just can go to the groove of rotatable propeller 8 like this, rotatable propeller 8 just can be in draw key axle 10 be pushed rotatable propeller 8 to upper lock core 2 under the promotion of stage clip 9; Groove on rotatable propeller 8 snaps in the convex surface of upper lock core 2 tail ends; Bigger displacement has also just taken place in draw key axle 10, because down lock core 6 is moving so far in above-mentioned action, the key on the draw key axle 10 interior with being stuck in dead bolt 11 keyways of the keyway 20 on it is just in time corresponding; Draw key axle 10 also just can be promoted to snap in down in the keyway 20 of lock core 6 by stage clip 9 smoothly like a cork; Owing to upper lock core 2 with the above-mentioned rotation of following lock core 6 in gone to the limit (promptly being blocked when being about 90 °) by pin, at this moment be rotated further key 1 and just can make down lock core 6 and upper lock core 2 with changeing, identical movement key axle 10 since also from originally with rear lock core 13 mutually embedding be transformed into and following lock core 6 phase embeddings; 13 pairs of draw key axles 10 of rear lock core no longer play restriction; The following lock core 6 of institute just can drive draw key axle 10 with changeing when rotating, equally also just dead bolt 11 is also together driven and turn over, thereby accomplish the process of unblanking.

When the key tooth flower that inserts not to the time when opening (violence takes place); Its shift fork 3 that moves in the fork pockets also can move along the V-shaped groove on following lock core 6 end faces when upper lock core 2 took place to change together with instrument in strong stubborn process; Its shift fork 3 just can be by inclined-plane jack-up when shift fork 3 moves to the inclined-plane of v-depression; And at this moment the breach on the troughs of belt lock pellet shot from a slingshot in the upper lock core 2 because of key tooth flower not to just can be interlaced separately; And the breach on all troughs of belt locks pellet shot from a slingshot 16 not with shift fork 3 on the pellet shot from a slingshot groove corresponding; Shift fork 3 breach that the pellet shot from a slingshot groove on it can't be locked on the pellet shot from a slingshot 16 from trough of belt when moving passes through like this, but pellet shot from a slingshot groove mouth all has been stuck in other positions (like Fig. 5, Fig. 6, shown in Figure 7) of trough of belt lock pellet shot from a slingshot 16; So shift fork 3 also just can't continue to move; And upper lock core 2 is rotated further under the drive of violent tool; Move the v-depression that shift fork 3 heads in the fork pockets just can block down lock core 6 like this on the upper lock core 2 and partly drive down lock core 6 rotations; Because draw key axle inlay card 10 this moment is in the keyway 20 of dead bolt 11 and rear lock core 13; Dead bolt 11 can not rotate; And almost do not relatively rotate between lock core 6 and the upper lock core 2 down, according to the narration of front, the groove mouth on the rotatable propeller 8 in the following lock core 6 because of with the mutual vertical convex surface that can't snap onto upper lock core 2 afterbodys of the convex surface of upper lock core 2 afterbodys in; Draw key axle 10 also just can't snap in down the keyway of lock core 6 and can only remain on original position; So dead bolt 11, rotates that lock core 6 down can make down just that lock core 6 will overcome when torsion increases that damping unit 12 produces because draw key axle 10 still is stuck in the keyway 20 of rear lock core 13 stopping resistance and together with upper lock core 2 with commentaries on classics, so and also just can not rotate because of inlay card situation dead bolt 11 not taking place with the draw key axle 10 of dead bolt 11 with following lock core 6 with embedding; Lockset also just can't be opened, the above-mentioned working condition of technical scheme of the present invention when opened by violence that be.
