Fig. 9 introduce in this lock driven by key axle (15) for promoting the operating principle of power plate (32) of key tongue (1) switch lock.In plan view 9a, (15) are key axle, and (29) are power sheet, and there is pointed bossy body its lower right side, and (28) are for the bossy body on power plate (32) or turn out body.In the time that key drives key axle (15) up time direction rotation, drive (29) rotation, in the time that the pointed bossy body on it rotates to (28) and locates and continue to rotate, promote bossy body (28) and move right.In plan view 9b, (30) be the upper bossy body of power plate (32), (31) be power sheet, its upper left side is just like figure concave surface, when driven its axle (15) up time direction rotation by key, in the time that the inclined-plane part of (31) moves to bossy body (30) and locates, bossy body (30) can move right to point at the bottom of the inclined-plane of (31), can promote (30) and return to left movement in the time returning.Fig. 9 c is power sheet (29) and (31) and power plate (32) constitutional diagram, is the figure that overlooks direction of Fig. 9 a, b.(32) be power plate, (33) are groove, and the arm (2) of key tongue stretches in this groove to drive key tongue.Fig. 9 d is the stereogram of power plate (32), the orbit hole that stretches out body (42) that hole (45) are key axis blocking body (40).

Figure 10 introduce in this lock driven by key axle (15) for promoting the operating principle of power plate (38) of spring (4).In Figure 10 a, when key axle (15) drives up time direction rotation by key, after the inclined-plane of power sheet (35) lower right side moved bossy body (34), lose and stop that bossy body (34) can move right.In the time returning, this inclined-plane again upper bossy body (34) of propulsion power sheet (38) returns to left movement.In Figure 10 b, (37) be the bossy body on power plate (38), (36) be power sheet, when should key driving key axle up time direction rotation, in the time that the chamfered portion of the upper left side on power sheet (36) moves to bossy body (37) and locates and continue to rotate, promote (37) and move right, in the time returning, (37) can move to left and return again.Figure 10 c is Figure 10 a, b and power plate (38) constitutional diagram, is the figure that overlooks direction of plan view 10a, b, and (39) are groove.Figure 10 d is power plate (38) stereogram.This figure introduces and is: drive the rotation of key axle by up time direction rotation key, by power sheet (35), (36), power plate (38) is moved right, when key returns, promote again to return again.In Figure 10 b, (107) contact is to introduce in warning circuit.

Figure 11 is the main top view of this lock key axle bumper plate (40).Plate in master map (41) left end goes out (dotted line part) to declivity, and expression can have two kinds of modes, that is: plate (41) can be straight, can be also that have a certain radian or bending.In figure, protrude upward bossy body (42), from Fig. 8, lock in the upper hole (26) of side panel (27) and stretch out, cylinder upper and lower two ends in the right are stretched into respectively in the hole (22) being fixed on panel (27) and (19).

Figure 12 is one group of spring leaf (43), and it act as extruding lock blade, makes it to be free to slide the corresponding a slice spring leaf of each blade.

Figure 13 is this lock simple view, for closing lock status.In front view, only draw key and promote key axle, promote leaf switch latching segment, the power plates of promotion key tongue (1) and spring leaf (4) etc. are not drawn, and they simply draw in top view.In this figure, only draw the relations such as the connection between each major part, every partial interior connection, control etc. can be with reference to the introductions in every part figure.In figure, dotted line keyhole is lock bottom opening point, and C point is for starting to promote (32) lockset position of coupler that moves to right in this figure, and A, B point is Figure 18 introduction.As seen from the figure, this lock has 8 blades (7), does track control respectively by the panel (132) at two ends, and they can not be horizontally slipped by the extruding of spring leaf (43) upward direction.(2) that the power plate (32) of being introduced by Fig. 9 promotes on key tongue (1) are located, so that strong tongue (1) closes or unblanks.The power plate (38) of being introduced by Figure 10 promotes spring leaf (4) to left movement, moves to motion end point left to promote each blade (7), decontrols each blade (7) and leave certain distance while moving right.The oblique upper left side of keyhole (12), the oblique upper right side of slurcam (14), each baffle plate (41) on key axle bumper plate (40) stretches in each self-corresponding cannelure (between each adjacent ring (13)), and makes left end maintain elastic force upwards by spring action.(44) be circular jump ring, to fix each below.Figure medium power plate (32) is in left summit, and groove (33) drives on key tongue (2), makes strong tongue (1) summit on track, closes lock status.Power plate (38) is in the left summit of its track, and groove (39) drives spring leaf (4) to left summit, promotes all blades (7) to the left summit of its track.The elastic force of spring leaf (4) is greater than the elastic force of spring leaf (43).

The principle of this lock-switch lock is: one group of the groove of unblanking (8) of each blade composition in lock.As in Figure 13 top view from top to bottom the set of locations of blade groove (8) become a, b, c, d, e, a, b, the c or 1,2,3,4,5,1,2,3 in Fig. 3, only have all grooves of unblanking (8) and key tongue are aligned, key tongue just can enter groove (8) drawback lock.If there is the not position in key tongue (1) of groove of unblanking of a blade, this blade enters groove by the tonguing of prevention key and unblanks; If there is a blade not move right at least length of A-B, on this blade, A-B section moves downward prevention key tongue.Because A-B section exceeds some than B-I section, so it,, by stoping key tongue to contact with the B-I section on other blade, also just can not be surveyed other blade, so only have, all blades of this lock are promoted together to the unlocking action that just may enter next step to the right.

Introduce the switch lock process of this lock below: set this lock blade from top to bottom for a, b, c, d, e, a, b, c in Fig. 3 or be called 1,2,3,4,5,1,2,3, key is for as shown in Figure 4.Key is inserted in keyhole, and now key is that air transport is moving, sets now for shutting end point, the initial point of unblanking.Up time direction rotation key, slurcam (14) promotes all blades and moves right together, after slurcam is crossed horizontal level, each blade rebounds left under elastic force effect, key continues rotation, when blade movement is to the position shown in Fig. 3 e, the tooth (11) of key promotes each self-corresponding blade again and moves right, promote slurcam (38) simultaneously and also move right (seeing Figure 10), before key rotates to horizontal level or in, make spring leaf (4) to the point of the right end that moves, and and leaf abscission, each blade is fixing by spring leaf (43).Key continues rotation, slurcam (14) and key have all promoted key axle bumper plate (40) inverse time direction rotation and have crossed, after baffle plate (40) returns again, key continues to rotate to C point, slurcam (32) moves right (Fig. 9) again, makes key tongue enter the groove of unblanking (8) drawback lock along axle up time direction rotation.So only have key axis blocking body on Fig. 9 middle orbit when vertex position, its block body (42) enters the cross track position of its orbit hole (45) upper end, the power plate of unblanking just can move to right and unblank, now key axis blocking body (41) all blocks key axle cannelure, so keyhole position now disconnects completely with each blade.(if key axis blocking body is vertex position in figure not, and its block body (42) is positioned at the vertical hole in the hole (45) of power plate (32), unblanks to stop the power plate of unblanking (32) to move to right).Key continues to rotate to lock bottom opening pecked line keyhole position again.The unblank key rotation of this lock is less than 360 °.Key returns while shutting, and key inverse time direction goes back to, and the power plate (32) that first promotes to unblank returns and shuts, and then continues rotation and is finally back to initial point, and each blade moves to left to end point, is the inverse process of the above-mentioned process of unblanking, no longer tired stating.

In this lock blade, be provided with the vacation groove of unblanking, its object is upset effect, and when the false groove of a certain blade is during in key tongue (1) position, the blade having is in true and false while unblanking between groove, and this vacation groove has the effect of the doubtful groove of unblanking.

Figure 14 is a kind of profile stereogram of the padlock of applying this technology.Due to this lock construction complexity, can not be as present padlock, from the assembling of lock body lateral opening hole or maintenance, more will be in order to ensure its anti-damage performance, so, this lock is packed in the box of shaping, install removable upper cover additional and keep in repair.(46) be lock shell, the keyhole on shell is still (12), and (47) are lock bridge, and (48) for locking cover plate, and cover plate (48) is connected firmly waterproof with lock box, drench with rain etc.(49) be screw, it is in the crossbeam of unblanking (left side) side, and (32) are the power plate of unblanking, and in this lock, controls lock bridge (47) switch lock by it.(50) be transverse plate, when its right-hand member is stuck in crossbeam bottom, right side, switch lock, crossbeam stretches out in the track of retraction, after stoping crossbeam to be unblanked, deviate from, after unblanking, left side crossbeam stretches out, and takes out screw (49) from its Kong Zhongke, and now transverse plate (50) is returned to the left by elastic force and detaches right side crossbeam, now, crossbeam can take off.After taking off crossbeam, the upper cover plate of lock just can take off, lock cap can be extracted (as mode figure) out from a side, also can be directly to depress and cover from top, cover plate now, on lock bridge, pasting upper cover of lock place and should establish bossy body, so that can not take off after shutting, in a word, only after unblanking, take off crossbeam and just can take off upper cover plate.If perforate from the side as existing padlock mode, also can make it to unblank to go to keep in repair again, but its safe fastness declines.

Figure 15 is U-shape lock stereogram.When for the existing U-shape lock such as electric motor car, motorcycle of picture, lock body shown in whole Figure 14 can be packed into lower transverse beam (136) inside of lock from limit, left side, unlock plate (32) is resembled Figure 19 and stretches out to the left (80), by the left side of its keyed lock bridge (137), also be the screw (49) as Figure 14, after unblanking, take off screw (135) and take out lock again, now screw (135) is fixed wtih the left side side plate (138) of lock.

This lock unblanks to move right for power plate (32), make key tonguing enter to unblank in groove (8), can make above-mentioned lock promote (32) upper any point, same, the upper any point of slurcam (32) all can be used as lock application.In fact the switch lock dead bolt that the power plate of this lock (32) is left and right directions, key tongue (1), (3) switch lock dead bolt for moving up and down.In the present embodiment (Figure 14,15), the power plate of unblanking (32) is locked in the groove (139) of establishing on lock bridge (47), (137) as existing lock.Also can be the switch lock crossbeam that promotes again, controls existing lock by unlock plate (32).

Figure 16 introduces the method that a kind of lock is connected with large dead bolt.When this lock is for safety cabinet, security door, car door etc. local time, need to install additional by the large dead bolt of this lock control and carry out control gate.In Figure 16, this locking key tongue stretches out body (3) as diagram shape, and (51) are for controlling the block body of large dead bolt, the elastic force that it keeps up, also can be as figure (19), it stretches out transverse plate left, in the middle of plate, establishes axle (82), and axle two ends are fixed in lock panel, make it to become a lever, like this, block body (51) is one, it and left end symmetry, in the time being damaged power, he can not move downward voluntarily like this.(52) be large dead bolt, (54), for stretching out body downwards, this large dead bolt is in closing lock status, and the dotted line on right side stretches out body (54) and represents to unblank the later position of stretching out body (54).(53) slurcam for being fixedly connected with key axle, other other part as locks such as blades does not draw.Here only introduce a kind of method for unlocking that is driven the large dead bolt of controlling by key axle.Its operating principle is as follows: while unblanking, key up time direction rotation, (key bit (11) and plate (14) promote the everythings such as blade to drive slurcam (53) rotation, as aforementioned), the final power plate (32) that promotes to unblank moves right, key tongue (1) is moved downward, enter the groove of unblanking (8) drawback lock, the body (3) that stretches out that is this figure moves downward, pull plate (51) moves downward, retreat and unblank and no longer hinder large dead bolt (52), set the now upper right side of slurcam (53) and just move to the left side of stretching out body (54), key continues rotation, making plate (53) promote large dead bolt stretches out body (54) and moves to right and unblank to dotted line position in figure.Key returns while shutting, the power plate (32) that first promotes to unblank moves to left and returns, making to stretch out body (3) moves upward and shuts, then, in the time that the upper left side of power plate (53) moves to the right edge of bossy body on large dead bolt (54) (right edge of the dotted line bossy body (54) of unblanking later), promoting bossy body (54) drives large dead bolt (52) to move to left, when final key is back to initial point, large dead bolt (52) is crossed block body (51), moved upward by elastic force effect block body (51) and block large dead bolt, so far, switch lock has moved.In the manner, the final stage of unblanking in key turns promotes large dead bolt (52) and unblanks, and returns to the final stage shutting promote again large dead bolt (52) and shut at key.Different from aforementioned lock, this lock key promotes again large dead bolt switch lock, should reserve the corresponding anglec of rotation, makes (29) promote in advance (32) and moves to right and unblank, and then key continues rotation again and promotes large dead bolt and retreat the lock that opens the door.

Figure 17 is a constitutional diagram, in closing lock status, is also to introduce a kind of mode that promotes large dead bolt switch gate, and the object of the manner is, when key returns and shuts after opening large dead bolt, first promotes large dead bolt and returns and shut.In Figure 17 a, large dead bolt is (56), and its body that stretches out is downwards (55).Push body (57) is fixedly connected with key axle (15), while unblanking, key rotarily drives push body (57) rotation, when its rotation is to stretching out body (55) when left side, set now (32) moved to right promote key tongue (1) (3) move downward, enter groove (8) drawback lock, then, while driving continuation rotation by key, promote large lock (56) and move to right and unblank to dotted line position, key returns to close and is locked to position in figure and shuts.In Figure 17 b, (58) also stretch out body for large dead bolt, and (59) are push body, it is fixedly connected with key axle, this figure is in closing lock status, and while now stretching out the upper A-B section of body (58) and push body (59) rotation, the circular arc that its tip becomes coincides.In the time that key rotation is unblanked, while driving push body (59) to rotate to B point, setting now key promotes (32) and moves to right, key tongue (1), (3) move down and unblank, key continues rotation and departs from A-B section, to being large dead bolt lock bottom opening point when position in figure, large dead bolt (56) stretches out body (58) and is arranged in figure dotted line position after being promoted to unblank by push body (57) in Figure 17 a.When key returns while shutting, first (59) promote to stretch out on large dead bolt (56) vertical section of BC on body (58), large dead bolt is moved to left to be shut, when to position shown in figure, close and be locked to end point, key continues rotation, and push body (59) moves along B-A section, and sets at this moment and promote (32) and move to left and shut, then, key continues rotation until initial point.Figure 17 c is the constitutional diagram of Figure 17 a, b.In this switch lock mode, large dead bolt is all controlled in the push body (57) and (59) that are driven by key axle, and they are not in same track.

Figure 18 is that this lock is applied to a kind of method of attachment on security door.For simple floor map.

Figure 19 is the three-dimensional exploded view of interior outer lock part part in Figure 18.(67) be the large dead bolt of security door, (15) are key axle, and (71) and (78) are push body, and they are fixedly connected with key axle.(72) be drawback lock tongue, (76) are its axle and handle (in door), (74) with (75) for to be fixedly connected with and to stretch out body with (76).(69) be the bossy body of bar (73) lower end.Inverse time direction rotation handle (76) when Men Neikai, makes push body (75) promote interior dead bolt (72) bottom righthand side, interior dead bolt (72) is moved to right and unblank to open the door.In this lock, large dead bolt (67) shuts, drive push body (60) up time directions (outdoors) rotation by handle above (door inside and outside establish coaxial handle) (61), promote the upper bossy body (62) of large dead bolt (67), large dead bolt is moved to left close to be locked to this figure position, close lock status, then handle returns to the origin position as figure under its elastic force effect.According to the switch lock mode of existing security door, interior dead bolt (72) locates to close lock status always, and upper inferior multi-faceted connecting rod, the dead bolt of large dead bolt (67) connection door are only locked whenever necessary.In the time that large dead bolt has not been locked, when Men Neikai, only need rotating handles (76) to open internal lock, and must open the lock with the key outdoors time, while opening the lock with the key, carry out the bossy body (70) of catch bar (73) by the slurcam (71) being fixedly connected with key axle and locate, make bar (73) driven rod (74), (75), and dead bolt (72) the interior dead bolt that moves to right out in final promotion.Simultaneously key rotation unblank (having inside and outside door), by the slurcam (78) being fixedly connected with key axle (15), what promote large dead bolt stretches out body (68), large dead bolt is moved to right and unblank to dotted line position in figure.The mode of push body in this figure (78), identical with push body (57) in Figure 17 a, just promote large dead bolt and move to right and unblank.

Process while simply introducing this lock external-open below, key is inserted in keyhole (12), clockwise direction rotates key, move to right and unblank when key axle promotes (32) (by the A → B in Figure 13), key tongue (1), (3) move downward, drive stopper body (77) move downward and depart from large dead bolt (67) afterwards, set now push body (78) and move to stretching out on the left of body (68) of large dead bolt (67), and promote large dead bolt (67) move to right and unblank (by the B point in Figure 13 to dotted line keyhole position) along with being rotated further of key, meanwhile, the bossy body (70) of push body (71) catch bar (73) is located, bar (73) is moved upward, finally make interior dead bolt (72) also move right and unblank, after opening the door, return to again key to initial point and transfer to key, so far this lock-switch lock process completes (promoting blade etc. as introduced in front lock), now stopper body (77) is positioned at the below of large dead bolt (67), door is by interior dead bolt (72) keyed.In the time locking again large dead bolt (67), need up time direction swing handle (61), finally make (60) to promote large dead bolt and shut and cross stopper body (77) to end point to left movement, block body (77) moves upward and by locked large dead bolt (67) under elastic force effect.The bossy body (69) of this figure king-rod (73) bottom, in the time that bar (73) moves upward, body (74) is stretched out in drive, make interior dead bolt (72) the interior dead bolt that moves to right out, rotate internal lock tongue handle (76) in door time, bar (73) is motionless.

In safe-guard door lock requires, external lock can be with same key unlocking, is to promote large dead bolt (67) by push body (78) to move to right and unblank by being loaded on lock in door, need not promote drawback lock tongue (72).Figure 19 is the three-dimensional exploded view (just simply draw, and track etc. fixing with door, lock box etc. is connected with existing lock side formula) of the inside and outside lock body part of Figure 18.Stopper body (77) and large dead bolt (67) are that inside and outside two locks share, door the inside and the outdoors push body of the lock of face (78), all after the slurcam of unblanking (32) the promotion key tongue (1) of each self-locking is unblanked, (68) that promote large dead bolt (67) are located, and make large dead bolt move right and unblank.The lock front of introducing is in the past all direction outdoors, the key of the lock of Men Neimen outside now, blade, each slurcams etc. will remain on same position, like this, just by the key direction of insertion of door inner face lock, by changing into by top and inserting from below insertion as top view in Figure 13, and the slurcam on top (32), etc. (38) parts are contained in below, the power arm of corresponding key tongue and stretch out body (2), (3), the power arm of spring leaf (4) etc. also changes towards below, each blade order is corresponding adjustment also, taking inside and outside door, use same key unlocking as standard.The direction of rotation of key unlocking sees to be also counterclockwise rotation in door.

Figure 19 is the stereo decomposing sketch of lock core body box (79) part of the lock shown in Figure 18.By lock box plate, the lock for interior external-open is connected as a single entity, two key tongues stretch out body (3) and stretch out lock box cover plate, and top exploded view is shown in its connection.Stretching out body (3) and can pulling block body (77) to unblank of interior external lock, non-interference.Right-hand member on the power plate of unblanking (32) of face lock stretches out body (80) outdoors, stopping that the bossy body (81) of establishing on bar (73) locates, making it not move to right while unblanking and can not move upward and open interior dead bolt (72) at plate (32).The rotation of slurcam (78) and (71) half, through larger, has reserved swing-around trajectory space on lock box.

In this lock, external lock is the same with existing safe-guard door lock, interior external lock alignment, and keyhole axle (15) is relative, and key tongue stretches out body (3) and also locates same position.All stretch in the groove of stopper plate (77), unblank can pull stopper plate (77) downwards, the groove lower-upper length of stopper plate (77) is larger, shut in key tongue (1), (3), after the stretching out body (3) and move upward of key tongue (1), can not promote (77) and move upward.

Figure 20 is the stereo decomposing schematic diagram of controlling button (83) part that large dead bolt (67) shuts in Figure 18.On large dead bolt (67), establish groove (66), left end is established inclined-plane (63), establish groove (85) at the upper side of key body (64), (84) be latch plate, its two ends are respectively by the two post controls up and down that are fixed in lock panel, the centre position of this latch plate is stretched in groove (85), with the position of flexible fastening button.The downside of key body (64) is established bossy body (65), and its limit, left side BC section is as figure inclined-plane, and place, its bottom surface AD limit right side of face is also the inclined-plane as figure.AB section on bossy body (65) stretches in the groove (66) on large dead bolt (67), can not move right and shut to control large dead bolt (due to this figure be in door, see lock side to, therefore large dead bolt shuts direction and Figure 18 opposite direction).The lower end (can be also upper end) of key body (64) can be moved to the right a little, and maintains elastic force left.The operating principle of this figure is such, according to the custom of existing security door, large dead bolt (67) is not shut sometimes, because of in this lock, control handle (61) that large dead bolt (67) shuts for door coaxially inside and outside, so this just requires control handle at will not rotate.The AB section of setting bossy body (65) in this figure stretches in the groove (66) of large dead bolt (67), for unlocking condition, in the time that needs are shut large dead bolt (67), first (83) push button in door, make the inclined-plane on the BC section limit on bossy body (65), limit, left side along groove (66) moves downward, the lower end of key body (64) is moved to right, after block body (65) is crossed large dead bolt (67), moved to left by elastic force effect key body (64) lower end returns, enter the bottom surface on limit, large dead bolt groove (66) left side, button can not upwards return again, but spring (84) makes it have the elastic force upwards returning, now, large dead bolt (67) loses and stops, can move right and shut.It in door, is inverse time direction, be outdoors up time direction swing handle (61), make push body (60) promote bossy body on large dead bolt (62), large dead bolt (67) is moved to right to be shut, closing to end point, set the bossy body (65) of having crossed stopper body (77) and button (83), stopper body (77) moves upward and shuts, button (83) loses and stops, under spring (84) effect, move upward and rebound, set the now height on the bottom surface of bossy body (65) (place, AD limit face) the right, on the left tip of large dead bolt ramp body (63).In the time unblanking, large dead bolt (67) returns under key drives, the inclined-plane (63) of large dead bolt promotes the lower surface of (65), button (83) is moved upward, large dead bolt is unblanked back after initial point, set the limit, left side of the groove (66) of large dead bolt (67), just cross the limit, left side of bossy body (65), it is place, AB limit face, under the effect of spring (84), button rebounds downwards again, the now AB section place face on the limit, left side of bossy body (65), be blocked in again the limit, left side of the groove (66) of large dead bolt, make it and can not move to right to shut, now the inside and outside handle (61) of door all can not at will rotate.

Figure 21 is connected control plane schematic diagram with time delay clock and warning circuit for this lock.

Figure 22 is that time delay clock connects the three-dimensional exploded view of controlling part, for Figure 21 overlooks direction.In figure, (15) are key axle, (79) be this lock body, (97) be time delay clock, (100), (104) are slurcam, (86), (103) are pushing piece, pushing piece (86) promotes push body (87), (100), and pushing piece (103) promotes (88), (104), and the mode that promotes to connect is Fig. 9,10 form.This illustrated object is to implement unlocking action when this lock (can only be located at face lock outdoors), that is: key is rotated, but in the situation that lock does not leave, this time delay clock can pin certain hour by this dead bolt, within this time, do not allow again to unblank, can continue to maintain the time of this locking if again unblank.Tool the manner is: in the upper end of the keyhole axle (15) of side chain (Figure 13 top view direction) outdoors, establish again the pushing piece (86) and (103) that are fixedly connected with keyhole axle, stretch out push body (being pass lock status in figure) in the lower-left side of pushing piece (86).(87) are stretched out in slurcam (100) left side downwards, and its right-hand member (seeing Figure 22 exploded view) has turning (89), and its tip is pointed, and it has the elastic force of left-hand.(90) for its right-hand member stretches out plate, promote the upper end (96) of time delay clock (97) power arm by this plate, (101) are the line shaft of time delay clock (97).Control panel (92) left end is fixed by the axle being fixed on lock box plate, right-hand member stretches out bossy body (95) downwards, it stretches in hole (98) from time delay clock, right-hand member protrudes upward block body (93) and (94), locate to align in block body (93) and turning (89), block body (94) moves upward and can enter the re-entrant angle (91) of establishing on stopper body (77) or dead bolt (3) and locate (only in the time closing lock status).This diagram operating principle, course of action is: in the time unblanking, up time direction rotation key, drive pushing piece (86) rotation, in the time rotating to the stretching out body (87) and locate of slurcam (100), promote (87) and stretch out plate, power plate (100) is moved right, its right-hand member promotes time delay clock arm rotation (propulsion power plate (104) is to left movement simultaneously), thereby (95) of the slurcam promotion control panel in time delay clock are located, block body (93) and (94) are moved upward, set now turning (89) locate to cross block body (93) so, (93) can only slightly move upward and contact with turning (89) left side soffit, and maintain elastic force upwards, set now, block body (94) not yet enters the corner establishing on stopper body (77) or dead bolt (3), key continues rotation, make after time delay clock power arm turns an angle, push body (86) with stretch out body (87) depart from, slurcam (104) is to left summit, slurcam (100) rebounds, time delay clock is started working and is returned voluntarily.Key continues rotation, set when lock internal key tongue (1) unblank after (as in Figure 13 by A to B point), making power sheet (103) promote to stretch out body (88) on slurcam (104) locates to move right again, the right-hand member of slurcam (104) connects the power arm (102) of time delay clock axle lower end, in the time moving to lock bottom opening point, propulsion power plate (104) is to point of the right end, time delay clock also returns to initial point, control panel (92) is under elastic force effect, and right-hand member moves downward and returns.While shutting, key returns, and in the time that push body (86) rotation turns back in the stretching out body (87) and locate of initial point, promotes to stretch out body (87) and moves upward, and stretches out body (87) until return to initial point thereby cross.In the time that key is not opened lock, now, because key bit promotes each blade, can not make the vaned groove of unblanking align with key tongue (1), therefore can not promoting key tongue (1), power plate (32) unblanks.So, only return to reopening.In the time that key returns, (87) stretching out body is subject to elastic force or promotes again to stretch out body (87) by push body (86) to return, after its turning (89) locate to move through block body (93) left, block body (93) loses and stops and move upward, make block body (94) extend into stopper body (77) or dead bolt (3) turning (91) thus in stop its (Figure 21 direction) motion downwards and unblank, key continues rotation promotion (87) and moves upward and cross (87) until return to initial point, want now again to unblank, the time delay clock such as only have to return to initial point, control volume (92) moves downward again, make block body (94) stretch out the turning of stopper body (77) or key tongue (3).If again unblank during this period, key rotation moves right push body (86) promotion push body (100), make its turning (89) locate to move right and pass through from the downside of block body (93), and time delay clock axle upper end power arm is pushed into again to point of the right end, equal to have lengthened delay time.This key of unblanking can not be unblanked right, locates because block body (94) stretches into (91), stopping stopper body decline unblank.

1., the time delay clock utmost point that is circuit the connected mode of this lock and warning circuit is:, its wiring is connected with (99) on time delay clock, lock body or door body are as another utmost point, in the time that slurcam (100) promotes the rotation of time delay clock arm, inner contact chip contacts with stopper body (95), sounds the alarm until time delay clock returns to initial point.2., stopper body (77) or the turning (91) of stretching out body (3) are located as a utmost point (with (77) or (3) insulation), connect warning circuit, using lock body, door body as another utmost point, in the time that lock does not leave slurcam (100) and returns, when entering in the turning of (77) or (3), connects stopper body (94) circuit, send chimes of doom, also be to continue to time delay clock to return to initial point, which is for rotating key unlocking, but lock just warning when not opening key and returning.

The connected mode of the warning circuit of this lock, also can be: 1., in Figure 10 b upside of (38) upper bossy body (37), on the swing-around trajectory in power sheet (36) outside, connect a utmost point contact (107) of warning circuit, this contact is fixing by the insulation of lock box plate, another utmost point of lock body or Men Tiwei, in the time unblanking, (36) power sheet rotation, in the time that its inclined-plane, upper left side moves to contact (107) and locates, two are extremely connected and sound the alarm, until key returns, power plate (36) and contact (107) are departed from.2., contact (107) are fixedly connected with power plate (32), like this, when key rotation is unblanked, after power sheet (36) and contact (107) being connected send warning, if (32) move to right and unblank, be with movable contact (107) disconnection that moves to right, chimes of doom stops.When returning while shutting, the power plate of unblanking returns again and connects, and chimes of doom sounds again, until power sheet (36) rotation departs from contact (107), rings two very short sound in which in the time opening and shut.If this lock is not opened to report to the police and is continued to key and return to power sheet (36) and depart from contact (107).

Figure 23 is the connected mode of warning circuit in a kind of lock, if pushing piece in Figure 10 b (36) is a utmost point, contact (109) is connected with plate (108), slurcam (108) right-hand member is dynamically connected with the power plate (32) of unblanking, it upwards establishes bossy body (111), left end is stuck in the downside of lever body (110) axle lower end bossy body (112), its left end has elastic force upwards, lever body (110) has inverse time direction elastic force, it in figure, is the point of the right end of lower end, bossy body (111) is arranged in the soffit (or separately establishing pushing piece) of Figure 10 b pushing piece (36), contact (109) can be wider flexible contact, connect to determine flexibly warning circuit the angle stopping, its operating principle is such, in the time that key drives the rotation of power sheet (36) up time to unblank, in the time that touching contact (109), connects on the inclined-plane of upper left hand hay cutter warning circuit, if key is correctly unblanked, (32) drive slurcam (108) to move to right, contact (109) and pushing piece (36) are departed from and disconnecting circuit, plate (108) moves right, its left tip and lever bossy body (112) depart from, its left end moves upward under elastic force effect, when driving, key returns while shutting, power plate (32) drives plate (108) to return to left movement, its left end stretches into the upper end of bossy body (112), key continues rotation and returns, the right lower end surface of pushing piece (36) promotes again bossy body (111), make the left end of plate (108) move downward promotion bossy body (112) to left movement and cross bossy body (112), lever body (110) (112) returns again afterwards, bossy body (112) is the top of the left end in plate (108) again, now pushing piece (36) departs from contact (109).If the process of unblanking above-mentioned key is incorrect, unblank power plate (32) and (108) do not move to right, warning circuit can not disconnect, and warning circuit connects until key returns, and contact (109) and pushing piece (36) are departed from.

Figure 24 is the floor map for the lock on car door, only represents the position of each part.

Figure 25 is the three-dimensional exploded view of Figure 24.This lock-switch lock side formula is as existing automobile door lock, inside and outside setting this lock, there is lock, inside and outside have handle arbitrarily to pull open dead bolt, door inner side is provided with the latch that blocks large dead bolt, and can pull open this latch while opening the lock with the key, different from safe-guard door lock is, and this is locked large dead bolt and is provided with and shuts spring, make it all the time in closing lock status, so just establish one and shut button (115), make its block body (114) stop the track that shuts of stopper body (117), shut and on button (115), have bossy body (120), its shape, function is similar to the bossy body (63) of Figure 20.Separately establish the button (113) that a control shuts button, its function, effect are as the button of Figure 20 (83), and groove is (122), block body (121).The inside and outside handle (123) with establishing of door, in the time that up time direction pulls out handle outdoors, drive is stretched out body (124) and is promoted the upper turning (125) of large dead bolt (118) and locate, promoting large dead bolt (118) moves right and unblanks to open the door, shake hands afterwards to return under elastic force effect, large dead bolt (118) also returns under spring action.(127) be a button, its right-hand member acting as by controlling lever (126) moves downward, the left end of lever is moved upward and stretch into the rear end of large dead bolt (118), unblank to stop it to move right, on key tongue (3), establish turning (128), establish groove (119) at the lower-left end of lever (126), turning (128) is stretched in this groove, in the time that unblanking to move downward, key tongue (3) pulls stopper body (117), also pull groove (119) to move downward together to depart from large dead bolt (118) track of unblanking that moves to right by this turning (128).(129) be the body that stretches out on large dead bolt (118), (130) body that stretches out for being fixedly connected with key axle, they resemble (55) and (57) in Figure 17 a, at the tongue of unblanking (1) afterwards, key continues rotation, make push body (130) promote to stretch out body (129), large dead bolt (118) is moved to right and unblank.This figure is that large dead bolt (118) closes lock status, for direction outdoors, shut button (115) for inside and outside same, be located at outdoors for inwardly pressing button, it in door, is the inner end that inwardly pulls button, block body (114) is positioned at the turning (116) of stopper body (117) to be located, and shuts to stop stopper body (117) right-hand member to move upward.The operating principle of this lock, course of action are such, and this lock is not shut at ordinary times, can pull at any time inside and outside handle (123), large dead bolt (118) is moved to right and unblank to open the door.Push button downwards (127), promotion lever (126) left upper end stretches into large dead bolt rear end and backs out thereafter lock to stop, and now, handle (123) is ineffective, upwards pulls button (127) can decontrol large dead bolt.

In the time that needs are locked this lock, first the control that is located at an inner side being shut to button (113) presses downwards, make its block body (121) enter the soffit (with reference to Figure 20) of the upper block body (120) of button (115), make block body (121) no longer stop (120), then (outdoors) press inwards button (115), make (114) run off the turning (116) on stopper body (117), stopper body (117) moves upward and keeps off the rear portion at large dead bolt (118) under elastic force effect, the inner surface of block body (114) in (117), and there is the elastic force returning, button (113) upwards pops into position again, so far this lock has shut.In the time unblanking, insert key, up time direction (outdoors) rotation, make key tongue (1) move downward unblank (before in this lock, stating), stretching out body (3) moves downward, and pull block body (117) move downward and unblank (if when now button (127) is also positioned at the lower position closing, also together its left end is left behind, button (127) is resetted), button (115) pops into position under elastic force effect, keeping off again at turning (116) locates, then be rotated further key, make push body (130) promote again to stretch out on large dead bolt body (129), dead bolt (118) is moved right unblank to open the door that (also can no longer make key promote large dead bolt (118) unblanks, unblank and just make key promote stopper body (117), large dead bolt is still opened the door by inside and outside handle (123)), then key returns, large dead bolt stretches out again under spring action, key tongue (1), (3) upwards return again, key is until return to terminal.

Because automobile high-speed motion vibrations are larger, for preventing because of vibrations or shutting unintentionally this lock, the bossy body of button (113) (121) can be changed into the shape as drawn figure (131), the bossy body (120) of button (115) is stuck in groove (131) at ordinary times, now button (113) can not be pressed downwards, setting the upper end of button (113) can inwardly slightly move, like this in the time shutting, must first promote button (113) inwardly moves, make bossy body (120) deviate from groove (131), and then push button downwards (113), after making block body (131) cross bossy body (120) soffit, be subject to the upper end of elastic force effect button (113) outwards to move and return, be stuck in the soffit of bossy body (120), after shutting button (115) inwardly motion shut, button (113) upwards rebounds again, finally after stopper body (117) is unblanked, button (115) returns, block body (120) enters again in groove (131).After the upper end of button (113) is made as and can be inwardly moved, button (113) can pressed, after its block body (121) or (131) enter the soffit of bossy body (120), inward direction promotes button (113) again, makes its above-mentioned action of returning to disappear.In Figure 20, in like manner also can change this figure mode during for security door into.

The figure that draws of lower left represents that stopper body (117) can change into from the side of large dead bolt and locks, locking key tongue (1), (3) move downward and unblank, pull the right-hand member of stopper body (117) to move right by inclined-plane etc., retreat the track of unblanking so that it departs from large dead bolt (118), the lock such as aforesaid security door in like manner also can be like this.

This lock Fig. 2 reed (4) of being hit by a bullet also can separate as spring leaf (43), makes the corresponding blade of each spring leaf.Yin Ben lock cannot technology unlocking, so, should be by digital the group record corresponding key bit of every lock, like this after key loss, as long as this group numeral is provided, again copy key, as key in Fig. 4 can be organized as: 1,2,3,4,5,1,2,3 or the mode such as a, b, c, d, e, a, b, c or other letter, numeral, symbol.This lock can form according to safety requirements the lock of different level of securitys, in less demanding lock, the block body in Figure 11 (40) can be gone to disappear.Ring (13) in Fig. 5 between each blade (7) also can go to disappear, if now there is block body (40), block body (40) can be changed into a whole plate.

In this lock, can the bossy body (28) on the power plate of unblanking (32) of Fig. 9 be changed into flexible, like this, in the time having larger destructive power on keyhole, can make key rotate to lock bottom opening point, but the power plate of unblanking (32) does not move to right and unblank.In Fig. 6, in (105), Fig. 7, (106) are the bossy body fixing with locking cover plate interlock, make the assembling of this lock can adopt modular mode.

Because this lock pin is built-in, so, can be at heavy metal plate or its dope layers such as the inner side such as lock box leadings, make it the comprehensive detection that stops the groove (8) to blade such as X ray completely and unblank.

Slurcam in this lock (14), in the time unblanking, first promoting each blade by it moves right to the effect of end point and is: while unblanking, all blades are shifted onto to point of the right end at every turn, can be detected the groove (8) of blade locate in case long-time after using.The track of each in this lock, fixing, connection etc. are not introduced, and are as the criterion in modes such as existing lock or machineries.In this lock Figure 13 top view, pushing piece (29) and (31) are all right on or below slurcam (32) respectively, as long as promoting (32), (29) move to right, (31) can promote (32) and move to left and return just, slurcam (38) is also like this.In this lock Figure 13, move right the again distance of A-B in Fig. 3 of blade (7), its groove (8) just aligns and can unblank with key tongue (1), the namely figure of a in Fig. 3, b figure is again the distance of mobile BC, and c figure adds CD more successively, and d figure adds DE again, e figure adds again EF again, and the vaned groove of institute (8) all aligns with key tongue (1).

This lock is in the time being used for safe-guard door lock, and with the lock shown in Figure 13, the key rotation angle of unblanking to promote to unblank is different.In Figure 13 front view, dotted line keyhole is lock bottom opening point position, and C point is for starting to promote power plate (32) starting point of unblanking that moves to right of unblanking.In the time need to promoting large dead bolt again by key for security door, safety cabinet etc., can establish A point for starting the move to right position of key point tongue (1) of slurcam (32), unblank to end point for key tongue (1) to B point, be to promote large dead bolt to unblank to dotted line keyhole position by B, it is as reclinate in figure left side that block body (40) now can change into, so that ahead of time keyhole now and blade are disconnected.

The keyhole of lock is generally straight up now, can be by downward-sloping the lock body right-hand member for the lock on security door in Figure 18, so that keyhole straight up, by key tongue (1) in the three-dimensional exploded view of Figure 18 stretch out body (3), still turn to stopper body (77) and unblank.Because the rotation of this lock key and leaf abscission and turn to after just unblank, so groove on the key can go to disappear.For the later trouble of the key that prevents loss, can be by the information of key bit, if the key of Fig. 4 is a, b, c, d, e, a, b, c, or the letter that can represent above-mentioned information such as 1,2,3,4,5,1,2,3, the numbering such as model of the symbol such as digital or well-regulated Chinese character and lock is given user together with key, like this, after losing key, above-mentioned information is provided, just can copy easily key.

When connection warning circuit in this lock, can be to add the modes such as vibration, light simultaneously.Also can be connected to other convenient other position of controlling and checking simultaneously, or the switch connecting as circuit such as startup shooting, phone, mobile phones.In this lock Figure 13, there are 8 blades, the same with existing lock, can there be as requested the different numbers of blade and difference number.

Above introduced lock can only anti-technology unlocking, introduces the method that prevents powerful picking lock core and the function of automatically changing key below again.

Figure 26 is for the promotion unlock key tongue switch lock that driven by key axle (15) and promote each blade and return the three-dimensional exploded view of part, and in figure, left side leads to the plan view of each counterpart.This figure is the improvement technology of Fig. 9 and Figure 10 part, and key axle can rotate arbitrarily, can be with reference to the introduction of figure 9,10.In aforesaid lock, set initial point and the stop of key revolution switch lock, in Fig. 9,10 each for shut end point, the initial point of unblanking, in Fig. 9, key axle can not rotate by another mistake clockwise.The lock that described Figure 26 introduces now, also change the top of the most advanced and sophisticated bossy body on pushing piece in Fig. 9 (29) right side into as below inclined-plane, also change below the left groove of pushing piece (31) into inclined-plane, like this, key band moving axis (15) just can rotate freely to any direction, thereby promotes to unblank power plate (32) side-to-side movement.In like manner the limit on the pushing piece in Figure 10 (36) right side is also changed into oblique, make key drive pushing piece (35) (36) also can rotate arbitrarily, thereby slurcam (38) side-to-side movement.When there being the HHT higher high tensile twisting key axle that exceedes general key intensity, and key bit not to time, unlock key tongue can not enter the groove drawback lock of unblanking.Now, the power plate of unblanking (149) can be to left movement, and key can be rotated arbitrarily.In addition in Figure 26, also change the flexure strip (4) that promotes each blade in Fig. 2 and return reset into plate (177), it is as diagram shape that the power arm (2) of unlock key tongue (1) in Fig. 1 is changed towards below, the power plate (32) of unblanking changes (149) shape in Figure 26 into, between its vertical bossy body (147) and the power arm of unlock key tongue (151), be connected by spring, like this, when to left movement, pull unlock key tongue (151) to unblank by spring at the power plate of unblanking (147), in the time moving right, move right and shut by the power arm of bossy body (148) promotion unlock key tongue (151).After figure Leaf return spring sheet changes plate into, it is different that pushing piece (142) and (144) are also introduced from Figure 10.The top is the bolt plate (140) of outer connection, located by key axle, stretched in its right ports (141) by unlock key tongue (151), and driving plate to move to realize switch lock, this mode can be used (sometimes only locking a side) in many examples.In fact in the lock that Figure 26 introduces, only has unlock key tonguing this kind of mode that enters to unblank to unblank in groove, the body that stretches out that in this figure can be also unlock key tongue turns out as dead bolt or for plate (140) is by the fixed axis location of unlock key tongue (151), be not connected with key axle, now, if key axle place has destructive power to make shaft distortion, damage and also can not unblank.Below is lock interior plate (153), and it act as (27) in Fig. 8.All parts of top stretch into axle (15) upper end successively, and are fixed by elastic circlip topmost, and the concrete course of action of this figure is together explained after having explained other principle.

Figure 27 is the three-dimensional exploded view of introducing the knob (158) for promoting to change key.In figure, locking interior plate (153) is same plate with Figure 26 middle and lower part plate (153), two vertical plate in left side (154) are the track fixed head of plate (149) and (143), and the left end of plate (149) and (143) stretches in two vertical plate (154).Hole (155) is the axis hole of key axle (15).Lower right side groove (168) stretches out track body hole for unlock key tongue (151).Knob (158) is for changing the line shaft of key, the dual-side of its arc bossy body (161) is subject to the control of the vertical plate (162) fixing with plate (153), shown in figure, for counterclockwise rotating end point, it can be a bit larger tham 180 ° by up time direction rotation.Lower right side is revolving part (164), by its borehole jack on post (169), make its top-right bossy body tip stretch into indicating positions in the figure that arc bossy body (170) locates, it will stop knob (158) up time direction rotation like this, its groove that stretches out to the left plate is clamped the body (Figure 26 direction) that protrudes upward of unlock key tongue (151), like this, after unblanking, unlock key tongue to motion, driven rotary part (164) up time direction rotation, make it protrude upward body and move right disengaging (170), thereby knob (158) can rotate, and be set in arc bossy body (170) in the whole process that knob (158) rotates to end point and all will stop (164) to return.The right-hand member of post (160) is enclosed within and locks on the post that interior plate (153) is fixedly connected with, it is upper as on the bossy body of diagram shape (159) that left end leans against knob (158), and post has the elastic force of inward direction, it act as and makes the knob (158) can autorotation.After knob (158) up time rotates to end point, post (160) leans against again in the plane of bossy body (159) inner side, makes equally it can autorotation.The unblank right-hand member fluted (150) of power plate (149), the post as schemed between indicated bossy body (161) and (165) of knob stretches in groove (150).The lower part of knob (158) is cylinder, and cylinder (165) and the same diameter of (167) two part, part between part and (165) and (167) between arc body (161) and cylinder (165) is with straight warp, (165) part is fixing by the lock interior plate (153) as figure, (167) part of lower end is fixed (with reference to lock panel (19) in figure 6 by lock outer side panel, introduce with (19) in Figure 13), this illustrated operating principle is introduced later again.

Figure 28 is the plan view that knob (158) and this lock key axle (15), lock blade (171), (178), unlock key tongue (151), the blade of the replacing key introduced of Figure 27 returns to power plate (145), flexure strip (172) combination, for Figure 26 and Figure 27 look up the simple view of direction, it is the frontal of lock.In this figure, lock blade is divided into upper and lower two parts, upper part (178) has this lock downward tooth (174) of groove (173) and right side of unblanking, lower part is its powered part, right-hand member has tooth (175) upwards, right-hand member is fluted (176) to the right, and in Figure 27, on knob, the post (166) between (167) and (165) part stretches in the vaned groove of institute.Low order end is to promote the plate (177) that blade returns, and for two part blades are connected firmly, draws 3 teeth and be connected (can change) in this figure, and there are 7 teeth upper part lower right side.This lock unlock key tongue (151) lower end is pointed, and there are 4 teeth in the left side of the groove of unblanking (173), and there are 5 teeth on right side.In Figure 28 a, unlock key tongue (151) is positioned at the top of the 1st tooth in the groove of unblanking (173) right side, and 3, the left side tooth in 7 teeth of 3 connection teeths and upper parts of lower part blade (171) is connected mutually.When blade (171) by key promote to the right 1 tooth pitch from time, unlock key tongue (151) just can enter in the groove of unblanking (173) and unblank.In Figure 28 b, 3 teeth of lower part are connected mutually with 3 teeth on the right side of upper part, at this moment unlock key tongue (151) is positioned at the tooth top of low order end on upper part blade, when now blade is subject to key to promote the distance of 5 teeth to the right, unlock key tongue (151) can enter in the groove of unblanking (173) and unblank.In like manner Figure 28 a middle and upper part part (178) is often moved to the left 1 tooth, the groove of unblanking is also moved to the left 1 tooth, also must do more physical exercises the to the right again distance of 1 tooth of key just can make unlock key tongue (151) enter the groove of unblanking (173) drawback lock, has namely converted the corresponding key bit of this blade.Conversion between them realizes by rotation knob (158), in the time of the knob in Figure 27 (158) up time direction rotation, the less cylinder of diameter between cylinder (165) and (167) part, drive all blade (171) right-hand members to move downward (Figure 28 direction) and make the two disengaging, set rotation to be a bit larger tham the object of 180 ° be that (the door back side) is can be bright fresh from lock outside and find out that variation has occurred knob (158) upper end (Figure 27 direction) groove direction, become incline direction, (vertically for Figure 27 rotates front position, rotate to end point rear for oblique).When knob (158) inverse time direction is returned, two part blades are together engaged again.In one row's blade (in Figure 13 being 8), (178) part and (171) part of blade are engaged in different teeth, the number of teeth one-tenth certain combination of groove to unlock key tongue makes to unblank, and the tooth of key is while getting up with corresponding blades arrangement, make unblanking groove part under unlock key tongue and unblanking of all blades.

Introduce Figure 26 below, 27, the course of action of the switch lock of lock, replacing key described in 28: in each figure, each part is the initial point of unblanking, shuts end dotted state, wherein the A point of (142), (144), (146), (152) is initial point place, and key can rotate freely to any direction.In Figure 28, key up time direction rotation is the direction of unblanking, inverse time direction rotation can not unblank (prizing-proof lock core function).While unblanking, key is inserted in keyhole, up time direction (Figure 28) rotarily drives key axle (15) rotation (Figure 26,27 is inverse time direction), drive pushing piece (142), (144), (146), (152) to rotate together, wherein pushing piece (146), (152) do not promote power plate (149) motion of unblanking between A-B.Move in the process of A point position at the B of pushing piece (142) and (144) point, pushing piece (144) is decontroled, pushing piece (142) slurcam (143) moves right that (this plate is the same with plate in Figure 10 (38), all promoting each blade returns), make blade Returning plate inverse time direction (Figure 28 direction) rotation be separated from each blade certain distance (this distance should be greater than slurcam (14) and the longest key bit promotes the length that each blade moves to right), meanwhile slurcam (14) also promotes each blade and moves right to point of the right end.Key continues rotation, in the time that the C of pushing piece (142) and (144) point moves to separately A point position, pushing piece (142) relieving, pushing piece (144) again slurcam (143) are back to point of the left end, meanwhile, slurcam (14) also moves and detaches each blade.Then key continues rotation, make the D point on pushing piece (142) and (144) move to A point position separately, pushing piece (144) relieving therebetween, pushing piece (142) be extremely right summit of slurcam (143) again, meanwhile, each tooth of key also promotes each self-corresponding blade and moves right, and now key rotates to level.After this, move to no longer slurcam (143) motion in the process of A point position at the E of pushing piece (142), (144) point.After this, key continues rotation, and in the time that key moves to the B point position of Figure 28, the B point of pushing piece (146) and (152) also moves to the A point position separately in Figure 26.Key continues rotation again, make the C point of pushing piece (146) and (152) move to A point position, BC hypotenuse promotes to unblank, and to left movement, (power plate of unblanking (32) in this plate and Fig. 9 all promotes to unblank power plate (149), different is that plate (32) is for directly promoting the power arm (2) of unlock key tongue, and plate (149) is to pull unlock key tongue (151) to unblank by spring), pull unlock key tongue (151) up time direction (Figure 28) rotation by spring, make its right-hand member stretch out body downwards and enter the groove of unblanking (173) drawback lock.Key continues rotation, make the D point of pushing piece (146) and (152) to A point position, in the stage of C-D, plate (143) and (149) are all without motion, the object that designs larger angle is: owing to there is no the powerful terminal of key switch lock in this lock, just key forwards approximately phase mean place to and just unblanks, when for security door (Figure 18), this process is that push body (78) promotes the process that large dead bolt (67) is unblanked.Also can in A point position, this puts elastic body, be fixed on lock body, at the D of pushing piece (146) or (152) point, place establishes a V-type groove, in the time that D point place rotates to this elastic body position, this elastic body enters in above-mentioned V-type groove, by key bright fresh feel unblank, and don't can stop key continue rotation.So far this lock process of unblanking completes.Now, movable block body (164) is subject to the drive of left end unlock key tongue (151), up time direction (Figure 27) rotation, and its upper right side stretches out body and has stretched out outside the upper projecting surface (170) of knob (158)

Introduce again the course of action of changing key below: by finding out in Figure 27, change the knob (158) of key at the back side of lock, now, clockwise direction (Figure 27 direction) rotation knob (158) point on earth, stopped by block body (162) and can not continue again rotation, in this process, block body post (160) inverse time direction rotation, knob (158) can be rotated, after knob (158) is screwed into end point, block body post (160) keeps off again in the flat edge of back, to stop its automatic rotation.

Knob in Figure 28 (158) is inverse time direction rotation, (166) part of small diameter has been rotated to below by top under the drive of knob post (167) and (165) part, thereby also drive the right-hand member of each blade (171) part also to move downward a segment distance, make to depart from interlock between the tooth (175) of blade (171) part and the tooth (174) of blade (178) part.Now, unlock key tongue (151) is lived with the groove of unblanking (173) interlock, and (178) part of blade can not be moved again.After above-mentioned replacing key knob (158) rotation, cylinder part on its post between arc bossy body (161) and cylinder (165), as the cylinder part between cylinder (165) and (167), he also drives the right-hand member of the push pedal of unblanking (149) to move downward (Figure 28 direction), Figure 26 and 27 is inward direction, make the power arm that promotes unlock key tongue (151) move right the body protruding upward (148) on the power plate of unblanking (149) shutting, also inwardly motion and be separated from the tracks of unlock key tongue (151) power arm, like this, in the time that the power plate of unblanking (148) moves right again, just can not promote unlock key tongue (151) again.

Change the knob (158) of key in rotation after: one, continue again rotation key, drive key axle (15) rotation, promote pushing piece (142), (144), (146), (152) continuation rotation.Pushing piece (142) and (144) are all returned as origin position in figure, pushing piece (142) is decontroled therebetween, pushing piece (144) promotes again blade and return to power plate (143) and return to left summit, pull again Returning plate (177) to move to left and return back to top a little, promote all blades (171) therebetween and return to again left summit.Pushing piece (146) and (152) are also returned as the origin position in figure, pushing piece (152) is decontroled, pushing piece (146) power plate (149) that promotes again to unblank moves to right to right summit, during this time owing to changing key knob (158) rotation, inwardly motion (Figure 26 direction) of power plate (149) makes to unblank, make to promote bossy body (148) and stretched out the tracks of unlock key tongue (151), unlock key tongue (151) is motion not, and, after the knob of changing key is rotating, the upper bossy body (170) of post (158) of large semi-circular also stops the right side at the upper right side of movable block body (164), make its can not another mistake time direction rotation return, this just makes after having rotated replacing key knob, unlock key tongue (151) will be always in unlocking condition.Two, after above-mentioned unblanking, key also can return again, until return to initial point, this process is the inverse process of the above-mentioned process of unblanking.

After key returns to initial point, key is extracted, the new key that will change again inserts keyhole, clockwise direction rotation is unblanked to end point, this process is the same with the above-mentioned process of unblanking, difference is, one, because the tooth of blade (171) and blade (178) two part interlocks is thrown off, so key has just promoted (171) below partly.Two, the track that has also departed from unlock key tongue (151) power arm due to the upper push body (148) of the push pedal of unblanking (149), unlock key tongue (151) does not also move, still in unlocking condition.Above-mentioned again with new key unlocking to end point, again the knob (158) of changing key is back to the present position as Figure 27, Figure 26,27, in 28, all parts return to again initial point, blade (171) and (178) two parts are interlocked again (because variation has occurred new key bit, having there is variation in the interlock between tooth (174) and (175) of blade, its objective is and reached after new key and blade (171) and (178) combination in unlocking condition).The upper left side of protruding push body (148) and be also back to unlock key tongue (151) power arm of power plate (149) of unblanking.And then continue rotation key to shutting initial point as position in figure, and can be also to make again key be back to initial point, the inverse process that each action is unlocking action therebetween, so far, this lock is changed key action and is completed.

Key can rotate arbitrarily, unblanks with antitheft picking lock core, can automatically change the function of key.

Sequence number in Figure 27 (156) is the track axis hole of unlock key tongue (151).(157) be lock panel fixing hole.(163) be lock body fixed leg hole.(132) be lock side plate.

Figure 28 a, b are with a part of two states, therefore do not mark sequence number in b figure.

Figure 26, in 27,28, before the power plate of unblanking does not move to left and unblanks, still locking as the aforementioned between the tooth of unlock key tongue and blade (178), between them, there is certain gap, so that can not technology survey, in the time that promotion unlock key tongue (151) moves downward, its tip blade that first interlock residence has, make it to move again, then, then continue unlocking action.Can not enter unlocking condition as long as there is a blade not move to left in this lock.In fact this lock is three kinds of status locks, taking pushing piece (152) as example, rotates at key, before its B point moves to A point for cannot unlocking condition, in the time that C point moves to A point place, be the process of unblanking, D point moves to A point for process after unblanking, to state in figure for closing lock status.

In this lock, enter key tongue part that the groove of unblanking unblanks and should be: taking unlock key tongue turning cylinder as the center of circle, the some of the circular arc taking this center of circle to key tongue as radius.

Figure 26, the interlock between 27,28 lock of introducing two part blades, in reality, key does not need to change many times, like this, (171) part of blade is only established a tooth, and (178) part is established two teeth, can be by the two design larger, interlock darker, more firm.

Figure 26,27,28 locks of introducing, due to the groove of unblanking that only has unlock key tongue (151) to enter blade a kind of mode of unblanking, so, should be by Figure 14, the application mode of the padlock in 15, changes into and pins right side, and the opening of Figure 15 should be on right side.

Because security door has inside and outside two locks, so, should by two knobs changing key up and down or left and right be arranged in the back side of door lock, from face behind the door: the knob of face lock is outdoors linked to face behind the door by gear, to change respectively key.

Due to this lock technology unlocking easily, for make can to join and renew key to client timely after losing key, the name etc. that can by this information setting be maybe by the information of key bit simple object easy to remember is together given client, joins in time and changes key so that client says the information of tooth or name.

This lock for door, when security door each parts should be the mode of existing door by dress, to facilitate by dress.As Figure 18, button (83) should be in 19,20: separately establish a button that can take off, promote (83) by this button.
