Fig. 9 introduces the dynamic of the power plate (32) for being used to promote key tongue (1) switch lock that is driven in this lock by key axle (15) Make principle.In plan 9a, (15) are key axle, and (29) are power piece, and there is pointed bossy body its lower right side, and (28) are power plate (32) bossy body on turns out body.When key drives key axle (15) up time direction to rotate, (29) rotation is driven, when thereon Pointed bossy body rotate to (28) place and continue rotation when, promote bossy body (28) move right.In plan 9b, (30) are Power plate (32) protrudes above body, and (31) are power piece, and its upper left side is just like figure concave surface, when driving its axle (15) up time by key When direction rotates, when the inclined-plane part of (31) moves to bossy body (30) place, bossy body (30) can be moved right to (31) Inclined-plane bottom point, can promote upon return (30) to left movement return.Fig. 9 c are power piece (29) and (31) and power plate (32) Constitutional diagram is Fig. 9 a, the figure of b overlook direction.(32) it is power plate, (33) are groove, and the arm (2) of key tongue is stretched into the groove To drive key tongue.Fig. 9 d are the stereogram of power plate (32), and hole (45) are the track of the stretching body (42) of key axis blocking body (40) Hole.

The action that Figure 10 introduces the power plate (38) for push the spring (4) driven in this lock by key axle (15) is former Reason.In Figure 10 a, when key axle (15) drives up time direction to rotate by key, when the inclined-plane of power piece (35) lower right side is moved through After bossy body (34), lose and stop that bossy body (34) can move right.Upon return, the inclined-plane and propulsion power piece (38) Body (34) is protruded above to return to left movement.In Figure 10 b, (37) are the bossy body on power plate (38), and (36) are power piece, similarly When key drives key axle up time direction to rotate, when the chamfered portion of the upper left side on power piece (36) moves to bossy body (37) place and continue rotation when, promote (37) move right, (37) and can moves to left return upon return.Figure 10 c be Figure 10 a, b with Power plate (38) constitutional diagram, it is the figure of plan 10a, b overlook direction, (39) are groove.Figure 10 d are that power plate (38) is three-dimensional Figure.This figure is described as：Rotating key by up time direction drives key axle to rotate, and by power piece (35), (36), makes power Plate (38) moves right, and when key returns again to, promotes and returns again.(107) contact is to be introduced in warning circuit in Figure 10 b.

Figure 11 is this lock key axle bumper plate (40) main top view.In master map plate (41) left end to it is oblique go out (dotted line part), Expression can have two ways, i.e.,：Plate (41) can be it is straight or have a certain radian or bending.In figure to Upper stretching bossy body (42), lock from Fig. 8 on side panel (27) and stretched out in hole (26), the right cylinder upper and lower ends are respectively protruding into solid It is scheduled in the hole (22) on panel (27) and (19) Nei.

Figure 12 is one group of spring leaf (43), and it act as extruding lock blade, and being allowed to can not slidably, and each blade is corresponding A piece of spring leaf.

Figure 13 is this lock simple view, to shut state.In front view, only draw key and promote key axle, promote leaf Piece switch lock part, power plate of key tongue (1) and spring leaf (4) etc. is promoted not draw, they simply draw in a top view.This figure In only draw the relations such as connection between each major part, per partial interior, connection, control etc. can refer to the introduction in every part figure. Dotted line keyhole is unlocking bottom point in figure, and C points are to start to promote (32) to move to right lockset position of coupler in this figure, and A, B point are Figure 18 introductions. It can be seen that this lock there are 8 blades (7), orbits controlling is made by the panel (132) at both ends respectively, they are by spring leaf (43) Upward direction extruding can not horizontally slip.(2) on key tongue (1) are promoted by the power plate (32) of Fig. 9 introductions, so that key tongue (1) off and on is locked.Power plate (38) the push the spring piece (4) introduced from Figure 10 is to left movement, to promote each blade (7) to the left Move to motion bottom point, decontroled when moving right each blade (7) and at a distance from.Keyhole (12) oblique upper left side, is pushed away Dynamic plate (14) oblique upper right side, each baffle plate (41) on key axle bumper plate (40) stretch into (each phase in each self-corresponding annular groove Between adjacent ring (13)), and left end is maintained upward elastic force by spring effect.(44) it is circular jump ring, it is following with fixation Each part.Power plate (32) is in left summit in figure, and groove (33) is driven on key tongue (2), key tongue (1) is in summit on track, Shut state.Power plate (38) is in the left summit of its track, and groove (39) drives spring leaf (4) to be promoted all to left summit Blade (7) to the left summit of its track.The elastic force of spring leaf (4) is more than the elastic force of spring leaf (43).

This lock-switch lock principle be：The unlocking groove (8) of each blade forms one group in lock.As in Figure 13 top views from It is upper and the set of locations of lower blade groove (8) turns into a, b, c, d, e, a, b, c or 1,2,3,4,5,1,2,3 in Fig. 3, only by institute Some unlocking grooves (8) align with key tongue, and key tongue could enter groove (8) drawback lock.If there is the unlocking groove of a blade The position of key tongue (1) is not at, then the blade will prevent key tonguing from entering groove unlocking；If have a blade do not move right to Few A-B length, then section A-B will prevent key tongue from moving downward on the blade.Because section A-B than B-I section is higher by some, institute So that it will prevent key tongue from being in contact with the B-I sections on other blades, and also other blades cannot be detected, so only All blades of this lock are promoted to the right together, are only possible to the unlocking action into next step.

The switch lock process of this lock is described below：It is a, b, c, d, e, a, b, c in Fig. 3 from top to bottom to set this lock blade Or be 1,2,3,4,5,1,2,3, then key is as shown in Figure 4.Insert a key into keyhole, now key moves for air transport, Setting is now to shut bottom point, unlocking initial point.Up time direction rotates key, then pushing plate (14) promote all blade together to Right motion, after pushing plate crosses horizontal level, each blade rebounds to the left under elastic force effect, and key continues to rotate, and works as leaf Piece is moved to after the position shown in Fig. 3 e, and the tooth (11) of key promotes each self-corresponding blade to move right again, promotes simultaneously Pushing plate (38) also moves right (see Figure 10), prior to or just when key rotates to horizontal level, makes spring leaf (4) to motion Right bottom point, and fixed with leaf abscission, each blade by spring leaf (43).Key continues to rotate, and pushing plate (14) and key are Promote key axle bumper plate (40) inverse time direction rotate and cross, after baffle plate (40) returns again to, key continue rotation to C points with Afterwards, then pushing plate (32) moves right (Fig. 9), key tongue is rotated into unlocking groove (8) drawback lock along axle up time direction.So When only key axis blocking body is in vertex position on Fig. 9 middle orbits, its block body (42) enters the transverse direction of its orbit hole (45) upper end Orbital position, unlocking power plate can just move to right unlocking, and now key axis blocking body (41) all blocks key axle annular groove, institute So that key hole site now is fully disconnected with each blade.(if key axis blocking body is not at vertex position in figure, its block body (42) then in the vertical hole in the hole (45) of power plate (32), to prevent unlocking power plate (32) from moving to right unlocking).Key followed by It is continuous to rotate to lock bottom opening pecked line key hole site.This lock unlocking key rotates less than 360 °.When key return is shut, key is inverse Shi Fangxiang is gone back to, and is first promoted unlocking power plate (32) to return and is shut, then proceedes to rotation and eventually return to origin, each blade moves to left It is no longer tired to state for the inverse process of above-mentioned unlocking process to bottom point.

False unlocking groove is provided with this lock blade, its purpose acts on for upset, when the false groove of a certain blade is in key tongue (1) during position, that is, when the blade that has is between true and false unlocking groove, the false groove has the effect of doubtful unlocking groove.

Figure 14 is a kind of profile stereogram of padlock using this technology.Because this lock construction is complicated, it is impossible to as present Padlock is the same, from lock body lateral opening hole assemble or repair, more will in order to ensure its anti-damage performance, so, by this lock loading In the box of shaping, removable upper lid maintenance is installed additional.(46) it is lock shell, the keyhole on shell is still (12), and (47) are lock Beam, (48) to lock cover plate, cover plate (48) is connected with lock box answers firm waterproof, drenches with rain.(49) it is screw, its horizontal stroke in unlocking Beam (left side) side, (32) are unlocking power plate, and lock bridge (47) switch lock is controlled by it in this lock.(50) it is transverse plate, its Crossbeam is stretched out in the track retracted when right-hand member is stuck in right side crossbeam bottom, switch lock, to prevent crossbeam from deviating from after unlocking, is being unlocked After, left side beams stretch out, and screw (49) are can be taken off from its hole, now transverse plate (50) is returned and departed to the left by elastic force Go out right side crossbeam, now, crossbeam can be removed.After removing crossbeam, the upper cover plate of lock can just be removed, and lock cap can be from side Extract (mode in such as figure) out or directly depress and cover from top, now, should be set at upper cover of lock on lock bridge convex Go out body, so that cover plate can not be removed after shutting, in a word, crossbeam is only removed after unlocking can just remove upper cover plate.If picture Existing padlock mode is the same from lateral opening hole, be allowed to unlock row maintenance again also can, but its securely property declines.

Figure 15 is U-shape lock stereogram., can be by whole Figure 14 when for as U-shape locks such as existing electric car, motorcycles The sill (136) that shown lock body loads lock from left side is internal, and unlocking plate (32) is stretched out to the left as Figure 19 (80), by the left side of its keyed lock bridge (137), and as Figure 14 screw (49), screw (135) is removed after unlocking Lock is further taken out, now the left side side plate (138) of screw (135) fixed lock.

This lock is unlocked to be moved right for power plate (32), key tonguing is entered in groove of unlocking (8), can be promoted above-mentioned lock (32) any point on, equally, any point can all be used as lock application in pushing plate (32).The actually power plate (32) of this lock For the switch lock dead bolt of left and right directions, key tongue (1), (3) are the switch lock dead bolt to move up and down.In the present embodiment (Figure 14,15), Unlocking power plate (32) locks lock bridge (47), in the groove (139) set on (137) as existing lock.Can also be by unlocking Plate (32) promotes, controlled the switch lock beams of existing lock again.

Figure 16 introduces a kind of and locks the method being connected with big dead bolt.When this is locked for safety cabinet, antitheft door, car door and other places , it is necessary to install the big dead bolt by this lock control additional to control door when square.This locking key tongue stretches out body (3) such as diagram shape, (51) in Figure 16 To control the block body of big dead bolt, elastic force that it keeps up or as figure (19), it stretches out transverse plate to the left, Axle (82) is set among plate, axle both ends are fixed in lock panel, make a lever, and so, block body (51) is one, it with it is left End is symmetrical, and so when by destructive power, he will not voluntarily move downward.(52) it is big dead bolt, (54), should to extend downwardly from body Big dead bolt is in the state that shuts, and the dotted line on right side stretches out the position that body (54) represents the later stretching body (54) of unlocking.(53) it is The pushing plate being fixedly connected with key axle, other of other such as blade locks do not draw.Here one kind is only introduced by key Axle drives the method for unlocking of the big dead bolt of control.Its operation principle is as follows：During unlocking, key up time direction rotates, and drives and promotes Plate (53) rotation (key bit (11) and plate (14) promote the everythings such as blade, such as foregoing), it is final to promote unlocking power plate (32) move right, move downward key tongue (1), into unlocking groove (8) drawback lock, i.e. the stretching body (3) of this figure is transported downwards Dynamic, pull plate (51) moves downward, and no longer hinders big dead bolt (52) to retreat and unlock, and sets the upper right side of now pushing plate (53) The left side for stretching out body (54) is just moved to, key continues to rotate, and makes plate (53) promote big dead bolt to stretch out body (54) and moves to right unlocking The dotted line position into figure.When key return is shut, first promote unlocking power plate (32) to move to left return, stretching body (3) is transported upwards It is dynamic to shut, then, when the upper left side of power plate (53) is moved to when big dead bolt protrudes above the right edge of body (54) (after unlocking Dotted line bossy body (54) right edge), promote bossy body (54) to drive big dead bolt (52) to move to left, when final key is back to original Point, big dead bolt (52) cross block body (51), are moved upwards by elastic force effect block body (51) and block big dead bolt, so far, switch Lock action is completed.In the manner, promote big dead bolt (52) to unlock in the final stage that key turns are unlocked, return and shut in key Final stage promote big dead bolt (52) to shut again.Unlike foregoing lock, this lock key promotes big dead bolt switch lock again, should The corresponding anglec of rotation is reserved, makes (29) to promote (32) to move to right unlocking in advance, after then key is further continued for the big dead bolt of rotation forces Back out door lock.

Figure 17 is a constitutional diagram, in the state that shuts, and introduces a kind of mode for promoting big dead bolt switch gate, the manner Purpose be, when key after opening big dead bolt is returned and shut, to promote big dead bolt to return first and shut.In Figure 17 a, big dead bolt is (56), its body that extends downwardly from is (55).Body (57) is promoted to be fixedly connected with key axle (15), key rotates drive and pushed away during unlocking Kinetoplast (57) rotates, and when it, which rotates, extremely stretches out on the left of body (55), now (32) have moved to right promotion key tongue (1) (3) downwards for setting Motion, has been enter into groove (8) drawback lock, then, when continuing rotation by key drive, promotes big lock (56) to move to right and unlocks to dotted line Position, key return shut into figure position and shut.In Figure 17 b, (58) also stretch out body for big dead bolt, and (59) are promotion body, It is fixedly connected with key axle, and this figure is in and shuts state, when now stretching out section A-B on body (58) and promoting body (59) rotation, Circular arc formed by its tip coincides.When key rotation is unlocked, when driving promotion body (59) rotation to B points, now key is set Spoon has promoted (32) to move to right, and key tongue (1), (3) have moved down unlocking, and key continues rotation and departed from section A-B, the position into figure Shi Wei great dead bolt unlocking bottom points, after big dead bolt (56) in Figure 17 a by promoting body (57) to promote unlocking, stretch out body (58) and be located in figure Dotted line position.When key, which returns, to be shut, (59) promote the BC vertical sections stretched out on big dead bolt (56) on body (58) first, make big Dead bolt, which moves to left, to be shut, and is shut when to position shown in figure to bottom point, and key continues to rotate, and promotes body (59) to be moved along B-A sections, And setting promotion (32) at this moment is moved to left and shut, then, key continues rotation until origin.Figure 17 c are Figure 17 a, b combination Figure.The promotion body (57) and (59) driven in this switch lock mode by key axle all controls big dead bolt, and they are not at same rail Road.

Figure 18 is a kind of connection method that this lock is applied on antitheft door.For simple floor map.

Figure 19 is the three-dimensional exploded view of interior outer lock part part in Figure 18.(67) it is the big dead bolt of antitheft door, (15) are key axle, (71) and (78) is promote body, and they are fixedly connected with key axle.(72) it is drawback lock tongue, (76) are its axle and handle (door It is interior), (74) and (75) are to be fixedly connected with stretching body with (76).(69) it is the bossy body of bar (73) lower end.Inverse time side during Men Neikai To rotating handles (76), make dead bolt (72) bottom righthand side in promotion body (75) promotion, interior dead bolt (72) is moved to right unlocking and open the door.This lock In big dead bolt (67) shut, driven by handle (door is inside and outside to set same axle handle) (61) above and promote body (60) up time direction (door Rotate outside), promote big dead bolt (67) to protrude above body (62), move to left big dead bolt and shut to this figure position, that is, shut state, then Handle returns to such as figure origin position under the effect of its elastic force.According to the switch lock mode of existing antitheft door, interior dead bolt (72) one Straight place shuts state, and big dead bolt (67) connects upper inferior multi-faceted connecting rod, the dead bolt of door, only locks whenever necessary.When big lock During unlocked of tongue, during Men Neikai, only need rotating handles (76) to open internal lock, and must be opened the lock with the key when outdoors, use key When spoon is unlocked, by the pushing plate (71) that is fixedly connected with key axle come bossy body (70) place of catch bar (73), make bar (73) Driven rod (74), (75), and finally promote interior dead bolt (72) to move to right out interior dead bolt.Key rotation simultaneously is unlocked (inside and outside door all Have), by the pushing plate (78) being fixedly connected with key axle (15), the stretching body (68) of big dead bolt is promoted, moves to right big dead bolt The dotted line position into figure and unlock.The mode of body (78) is promoted in this figure, with promoting body (57) identical in Figure 17 a, is simply promoted Big dead bolt moves to right unlocking.

Process during this lock external-open is following is a brief introduction of, is inserted a key into keyhole (12), rotationally clockwise key Spoon, when key axle promotes (32) to move to right unlocking (by A → B in Figure 13), key tongue (1), (3) move downward, and drive stopper body (77) move downward after departing from big dead bolt (67), setting now promotes body (78) to move to the stretching body of big dead bolt (67) (68) left side, and promote big dead bolt (67) to move to right unlocking (by the B points in Figure 13 to dotted line key with being rotated further for key Hole site), at the same time, bossy body (70) place of body (71) catch bar (73) is promoted, bar (73) is moved upwards, finally made interior Dead bolt (72) also moves right unlocking, and key to origin is returned again to after opening the door and transfers to key, so far this lock-switch lock process is complete Into (promoting blade etc. as introduced in preceding lock), now stopper body (77) is located at the lower section of big dead bolt (67), and door is by interior dead bolt (72) keyed.When locking big dead bolt (67) again, up time direction swing handle (61) is needed, finally makes (60) to promote big dead bolt to transport to the left Dynamic to shut to bottom point and cross stopper body (77), block body (77) moves and locks big dead bolt (67) upwards under elastic force effect Extremely.The bossy body (69) of bar (73) bottom in this figure, when bar (73) moves upwards, drive and stretch out body (74), make interior dead bolt (72) interior dead bolt is moved to right out, in door internal rotation during dead bolt handle (76), bar (73) is motionless.

External lock can be by promotion body (78) by loaded on the lock in door with same key unlocking in safe-guard door lock requirement Big dead bolt (67) is promoted to move to right unlocking, without promoting drawback lock tongue (72).Figure 19 is the vertical of Figure 18 inside and outside lock body part Body exploded view (is simply simply drawn, be connected with fixations and track etc. such as door, lock boxes in a manner of existing lock).Stopper body (77) and big Dead bolt (67) is that inside and outside two locks share, and with the promotion body (78) of the lock in face outdoors inside door, is all pushed away in the unlocking of each self-locking After dynamic plate (32) promotes key tongue (1) unlocking, (68) place of big dead bolt (67) is promoted, big dead bolt is moved right and is unlocked.With The lock front of preceding introduction is all direction outdoors, and the key of the lock outside present door inside door, blade, each pushing plate etc. will be maintained at same One position, so, the key direction of insertion for just locking door inner face, it is changed to by the insertion from below of top view in such as Figure 13 by top Insertion, and the part such as the pushing plate (32) on top, (38) be mounted in lower section, the power arm and stretching body (2) of corresponding key tongue, (3), Power arm of spring leaf (4) etc. also changes downward, and each blade order also accordingly adjusts, same key unlocking to be used inside and outside door For standard.The direction of rotation of key unlocking sees also be counterclockwise rotates out of door.

Figure 19 is the stereo decomposing sketch of lock core body box (79) part of the lock shown in Figure 18.It will be used for by lock box plate inside and outside The lock opened is connected as a single entity, and two key tongues stretch out body (3) and stretch out lock box cover plate, and it, which is connected, sees top exploded view.The stretching of interior external lock Body (3) can pull block body (77) to unlock, non-interference.The right-hand member on the unlocking power plate (32) of face lock stretches out body outdoors (80) bossy body (81) place set on bar (73), is block, it is opened when plate (32) does not move to right unlocking from moving upwards Interior dead bolt (72).The rotation of pushing plate (78) and (71) half leaves swing-around trajectory space through larger on lock box.

External lock is as existing safe-guard door lock in this lock, and interior external lock alignment, relatively, key tongue stretches out body to key hole axle (15) (3) same position is also located.All stretch into the groove of stopper plate (77), so that stopper plate (77) unlocking, stopper plate can be pulled downward on (77) groove lower-upper length is larger, is shut, after the upward motion of the stretching body of key tongue (1) (3) in key tongue (1), (3), will not (77) are promoted to move upwards.

Figure 20 is the stereo decomposing schematic diagram of button (83) part for controlling big dead bolt (67) to shut in Figure 18.In big dead bolt (67) groove (66) is set on, left end sets inclined-plane (63), and groove (85) is set in the upper side of key body (64), and (84) are latch plate, Its both ends is controlled by two posts up and down being fixed in lock panel respectively, and the centre position of the latch plate is stretched into groove (85), with The position of flexible fastening button.The downside of key body (64) sets bossy body (65), and its left side BC sections are such as figure inclined-plane, under it Right side of face where the AD sides of bottom surface is also the inclined-plane such as figure.The groove (66) that AB sections on bossy body (65) are stretched on big dead bolt (67) It is interior, shut that (because this figure is that lock direction is seen in door, therefore big dead bolt shuts direction and Figure 18 to control big dead bolt to move right In the opposite direction).The lower end (can also be upper end) of key body (64) can somewhat move to the right, and maintain elastic force to the left.This The operation principle of figure is such, and according to the custom of existing antitheft door, big dead bolt (67) is not shut sometimes, because being controlled in this lock The handle (61) that big dead bolt (67) is shut is coaxial inside and outside door, so this requires control handle at will to rotate.In this figure The AB sections of setting bossy body (65) are stretched into the grooves (66) of big dead bolt (67), are unlocking condition, when needing big dead bolt (67) When shutting, push button (83) first in door, make the inclined-plane on the BC sections side on bossy body (65), along the left side of groove (66) Move downward, move to right the lower end of key body (64), after block body (65) more excessive dead bolt (67), key body is acted on by elastic force (64) lower end moves to left return, and into the bottom surface of big dead bolt groove (66) left side, button can not return up again, but spring (84) The elastic force returned up is made it have, now, big dead bolt (67) loses stop, can move right and shut.It is inverse in door Shi Fangxiang, it is being outdoors up time direction swing handle (61), is making promotion body (60) promote big dead bolt to protrude above body (62), make to lock greatly Tongue (67), which moves to right, to be shut, and after closing to bottom point, setting has passed past the bossy body (65) of stopper body (77) and button (83), stopper Motion is shut body (77) upwards, and button (83) loses stop, and motion is rebounded upwards under spring (84) effect, and setting is now protruded Height on the right of the bottom surface (face where AD sides) of body (65), on the left tip of big dead bolt ramp body (63).When opening During lock, big dead bolt (67) returns under key drive, and the inclined-plane (63) of big dead bolt promotes the lower surface of (65), make button (83) to Upper motion, after big dead bolt unlocking Aligning control, the left side of the groove (66) of big dead bolt (67) is set, goes just past bossy body (65) face where left side, i.e. AB sides, button rebounds downwards again in the presence of spring (84), now a left side for bossy body (65) Face where the AB sections of side, is blocked in the left side of the groove (66) of big dead bolt, is allowed to and can not move to right shut, now in door again Outer handle (61) can not be rotated at will.

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

Figure 22 is the three-dimensional exploded view of delay clock connection control part, is Figure 21 overlook directions.(15) are key axle in figure, (79) it is this lock body, (97) are delay clock, and (100), (104) are pushing plate, and (86), (103) promote piece (86) to push away to promote piece It is dynamic to promote body (87), (100), promote piece (103) to promote (88), (104), the mode for promoting connection is Fig. 9,10 form.This The purpose of diagram is to work as this lock (can only be located at face lock outdoors) to implement unlocking action, i.e.,：Key is rotated, but is locked not In the case of having out, this lock dead bolt can be pinned certain time by the delay clock, not allow to unlock again within the time, if again Unlock and then may proceed to maintain the time of the locking.Having the manner is：In the upper end of key hole axle (15) of side chain outdoors, (Figure 13 bows View direction), then the promotion piece (86) being fixedly connected with key hole axle and (103) are set, stretched out promoting the lower left side of piece (86) Promote body (being to shut state in figure).(87) are extended downwardly from the left of pushing plate (100), its right-hand member has turning (see Figure 22 exploded views) (89), its tip is pointed, and it has the elastic force of left-hand.(90) plate is stretched out for its right-hand member, promotes delay clock (97) dynamic by the plate The upper end (96) of the arm of force, (101) are the line shaft of delay clock (97).Control panel (92) left end is consolidated by the axle being fixed on lock box plate Fixed, right-hand member extends downwardly from bossy body (95), it from being stretched on delay clock in hole (98), right-hand member stretch out upwards block body (93) and (94), block body (93) is aligned with turning (89) place, and block body (94) is moved to enter on stopper body (77) or dead bolt (3) upwards and set Re-entrant angle (91) place (only when shutting state).This diagram operation principle, action process are：When unlocking, the rotation of up time direction Turn key, drive and promote piece (86) rotation, when rotating to stretching body (87) place of pushing plate (100), promote (87) to stretch out plate, Power plate (100) is moved right, its right-hand member promotes delay clock arm rotation (while propulsion power plate (104) to left movement), from And the pushing plate in delay clock is promoted (95) place of control panel, block body (93) and (94) is moved upwards, set now turning (89) place have passed past block body (93) so, (93) can only move slightly up to be contacted with lower surface on the left of turning (89), and is maintained Upward elastic force, now, block body (94) not yet enters on stopper body (77) or dead bolt (3) corner set for setting, and key continues Rotation, make after delay clock power arm turns an angle, to promote body (86) with stretching out body (87) to depart from, pushing plate (104) is extremely Left summit, pushing plate (100) are rebounded, and delay clock, which is started working, voluntarily to be returned.Key continues to rotate, and setting is when lock internal key tongue (1) (by A to B points in such as Figure 13) after unlocking, then power piece (103) is set to promote stretching body (88) place in pushing plate (104) to transport to the right It is dynamic, the power arm (102) of the right-hand member connection delay clock axle lower end of pushing plate (104), when moving to unlocking bottom point, propulsion power Plate (104) is to right bottom point, and delay clock also returns to origin, and for control panel (92) under elastic force effect, right-hand member moves downward return.Shut When, key return, when promote body (86) rotation return to be in origin stretching body (87) place when, promote stretch out body (87) to Upper motion, body (87) is stretched out until returning to origin so as to cross.When key is not opened lock, now, because key bit promotes respectively Blade, it is impossible to make the vaned unlocking groove of institute be alignd with key tongue (1), therefore power plate (32) can not promote key tongue (1) to unlock.Institute Only to return and reopen.When key returns, (87) stretch out body and promote stretching body (87) to return again by elastic force or by promotion body (86) Return, when its turning (89) place to left movement by block body (93) after, block body (93) lose stop upwards motion, make block body (94) It extend into the turning (91) of stopper body (77) or dead bolt (3) so as to prevent its (Figure 21 directions) motion downwards and unlocks, key Continue rotation forces (87) up and over (87) until returning to origin, want to unlock again now, only wait delay clock Origin is returned to, control volume (92) moves downward again, block body (94) is stretched out the turning of stopper body (77) or key tongue (3).In this phase Unlocked again in if, key rotation makes promotion body (86) promote body (100) to move right, and makes its turning (89) place from gear Moved right on the downside of body (93) by and delay clock axle upper end power arm being pushed into right bottom point, increasing delay in fact again Time.This is unlocked, and no matter key right all without unlocking, because block body (94) has stretched into (91) place, is block under stopper body Drop is unlocked.

The connected mode of this lock and warning circuit is：1., delay clock be circuit a pole, its wiring with delay clock on (99) Connection, lock body OR gate body is as another pole, when pushing plate (100) promotes the arm rotation of delay clock, interior contact piece and stopper body (95) contact, sound the alarm until delay clock returns to origin.2., by stopper body (77) or stretch out body (3) turning (91) place (insulated as a pole with (77) or (3)), connect warning circuit, using lock body, door body as another pole, when lock does not open pushing plate (100) when returning, stopper body (94) connects circuit when entering in the turning of (77) or (3), sends alarm, and continues to prolonging Clock returns to origin, and which is has rotated key unlocking, but lock is not opened when key returns and just alarmed.

The connected mode of the warning circuit of this lock or：1., (38) protrude above the upside of body (37) in figure 10b, A pole contact (107) of warning circuit is connected on the swing-around trajectory on the outside of power piece (36), the contact is insulated solid by lock box plate Fixed, lock body OR gate body is another pole, when unlocking, (36) power piece rotation, when its upper left side inclined-plane moves to contact (107) place When, two, which are extremely connected, sounds the alarm, and power plate (36) is departed from contact (107) until key returns.2., by contact (107) It is fixedly connected with power plate (32), so, is unlocked when key rotates, power piece (36) is connected with contact (107) and send alarm Afterwards, if (32) move to right unlocking, band movable contact (107) moves to right disconnection, and alarm stops.When return is shut, unlocking power Plate is returned and is again coupled to, and alarm sounds again, until power piece (36) rotation departs from contact (107), in which open with Two very short sound are rung when shutting.Alarm continues to return to power piece (36) and contact (107) disengaging to key if this lock is not opened.

Figure 23 is the connected mode of warning circuit in a kind of lock, if it is a pole that piece (36) is promoted in Figure 10 b, contact (109) it is connected with plate (108), pushing plate (108) right-hand member and the dynamic connection of unlocking power plate (32), it sets bossy body (111) upwards, Left end is stuck in the downside of lever body (110) axle lower end bossy body (112), and its left end has upward elastic force, and lever body (110) has Inverse time direction elastic force, is the right bottom point of lower end in figure, and bossy body (111), which be located at, promotes the lower surface of piece (36) (or separately in Figure 10 b If promoting piece), contact (109) can be wider elastic contact, flexibly to determine that warning circuit connects the angle stopped, its Operation principle is such, when key drives the rotation of power piece (36) up time to unlock, when the contact of incline plane that upper left is cut up with a hay cutter to contact (109) warning circuit is connected when, if key is correctly unlocked, (32) drive pushing plate (108) move to right, make contact (109) with Promotion piece (36) departs from and disconnecting circuit, plate (108) move right, and its left tip departs from lever bossy body (112), its left end Moved upwards under elastic force effect, when key drives return to shut, power plate (32) drives plate (108) to be returned to left movement, Its left end stretches into the upper end of bossy body (112), and key continues rotation and returned, and promotes the right lower end surface of piece (36) to promote bossy body again (111), move downward the left end of plate (108) to promote bossy body (112) to left movement and cross bossy body (112), afterwards thick stick The body of rod (110) (112) returns again, and bossy body (112) above the left end in plate (108), now promotes piece (36) with touching again Piece (109) departs from.If above-mentioned unlocking process key is incorrect, unlocking power plate (32) and (108) do not move to right, then alarm electricity Road will not disconnect, and warning circuit connection makes contact (109) with promoting piece (36) to depart from until key return.

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

Figure 25 is Figure 24 three-dimensional exploded view.This lock-switch locks for example existing automobile door lock of mode, and setting inside and outside this lock has Lock, it is inside and outside to there is handle arbitrarily to pull open dead bolt, it can be pulled open when being provided with the latch for blocking big dead bolt on the inside of door, and opening the lock with the key The latch, the big dead bolt of this lock unlike safe-guard door lock are provided with and shut spring, it in state is shut, is thus set all the time One shuts button (115), makes what its block body (114) block stopper body (117) to shut track, shutting on button (115) has Bossy body (120), its shape, function are similar to Figure 20 bossy body (63).The button (113) that a control shuts button separately is set, Its function, effect such as Figure 20 button (83), groove is (122), block body (121).With the handle (123) set inside and outside door, work as door When outer up time direction pulls out handle, drive and stretch out turning (125) place on the big dead bolt (118) of body (124) promotion, promote big lock Tongue (118) moves right unlocking and opened the door, and shakes hands to return in the case where elastic force acts on afterwards, big dead bolt (118) is also returned under the action of the spring Return.(127) it is a button, it act as moving downward by the right-hand member of control lever (126), the left end of lever is moved upwards The rear end of big dead bolt (118) is stretched into, to prevent it from moving right unlocking, turning (128) is set on key tongue (3), in lever (126) Lower-left end set groove (119), turning (128) are stretched into the groove, when key tongue (3) unlock move downward when pull stopper body (117), also groove (119) is pulled to move downwardly together to depart from the rail that big dead bolt (118) moves to right unlocking by the turning (128) Road.(129) it is the stretching body on big dead bolt (118), (130) are the stretching body being fixedly connected with key axle, and they are just as Figure 17 a In (55) and (57), after unlocking tongue (1), key continues to rotate, and promotes promotion body (130) and stretches out body (129), makes big Dead bolt (118) moves to right unlocking.This figure is that big dead bolt (118) shuts state, and for direction outdoors, it is same for inside and outside to shut button (115) One, it is outdoors inside depresses button to be located at, and is the inside inner end for pulling button in door, and block body (114) is located at stopper body (117) turning (116) place, to prevent stopper body (117) right-hand member, motion is shut upwards.The operation principle of this lock, action process It is such, usually this lock is not shut, and can pull inside and outside handle (123) at any time, big dead bolt (118) is moved to right unlocking and is opened the door. Push button downwards (127), promote lever (126) left upper end to stretch into big dead bolt rear end to prevent to back out lock thereafter, now, handle (123) ineffective, big dead bolt can be decontroled by pulling up button (127).

When needing to lock on this lock, will first be located on the inside of control shut button (113) and press downwards, make its block body (121) enter the lower surface (with reference to figure 20) of block body (120) on button (115), block body (121) is no longer stopped (120), then (outdoors) depresses button (115) inwards, make (114) to run off the turning (116) on stopper body (117), stopper body (117) is in elastic force Moving and keep off at the rear portion of big dead bolt (118) upwards under effect, block body (114) is in the inner surface of (117), and with return Elastic force, button (113) and is popped into position upwards, and so far this lock shuts completion.When unlocking, key, up time direction (door are inserted Rotate outside), key tongue (1) is moved downward unlockings (with reference to being described before in this lock), stretching body (3) moves downward, and pulls block body (117) move downward and unlock (if now button (127) also is located at the lower position that close, also its left end is left behind together, Reset button (127)), button (115) pops into position under elastic force effect, keeps off again at turning (116) place, then proceedes to rotate Key, promotion body (130) is promoted again and body (129) is stretched out on big dead bolt, dead bolt (118) is moved right unlocking enabling and (also may be used No longer to make key promote big dead bolt (118) to unlock, and key is simply set to promote stopper body (117) to unlock, big dead bolt is still by interior Outer handle (123) is opened the door), then key returns, and big dead bolt stretches out again under the action of the spring, and key tongue (1), (3) return up again, Key is until return to terminal.

, can be by button (113) to prevent because shaking or shutting this lock unintentionally because automobile high-speed motion vibrations are larger Bossy body (121) is changed to such as the shape of extraction figure further groove (131), make the bossy body (120) of button (115) usually be stuck in groove (131) in, now button (113) can not be pressed downwards, and the upper end of setting button (113) inwardly can slightly move, and so shut When, it is necessary to first promote (113) inwardly to move, bossy body (120) is deviate from groove (131), then push button still further below (113), make after groove (131) crosses bossy body (120) lower surface, the upper end that button (113) is acted on by elastic force moves out Return, be stuck in the lower surface of bossy body (120), after shutting the inside motion of button (115) and shutting, button (113) upsprings again Return, finally after stopper body (117) unlocking, button (115) returns, and block body (120) enters in groove (131) again.By button (113) upper end is set to after can inwardly moving, and can press button (113), its block body (121) or groove (131) enter After the lower surface for entering bossy body (120), then inward direction promotes button (113), returns it to above-mentioned action of going to disappear.Figure 20 In be used to similarly can also be changed to this figure mode during antitheft door.

The extraction figure of lower left represents that stopper body (117) is readily modified as locking from the side of big dead bolt, locking key tongue (1), (3) Unlocking is moved downward, the right-hand member for pulling stopper body (117) by inclined-plane etc. moves right, after disengaging it from big dead bolt (118) Backing out the lock such as the track of lock, foregoing antitheft door similarly can also be such.

Spring leaf (4) can also separate as spring leaf (43) in this lock Fig. 2, make the corresponding leaf of each spring leaf Piece.Yin Ben lock can not technology unlocking, so, should by every lock key bit corresponding to digital group record, so lost in key After mistake, as long as providing group numeral, can copy key again, as key can be organized as in Fig. 4：1st, 2,3,4,5,1,2,3 or A, the mode such as b, c, d, e, a, b, c or other letter, numeral, symbol.This lock can form different level of securitys according to safety requirements Lock, the block body (40) in Figure 11 can be gone to disappear in less demanding lock.Ring (13) in Fig. 5 between each blade (7) It can go to disappear, if now there is block body (40), block body (40) can be changed to one piece of whole plate.

Bossy body (28) on Fig. 9 unlocking power plate (32) can be changed to elasticity, so, when on keyhole in this lock When having larger destructive power, key can be made to rotate to unlocking bottom point, but unlocking power plate (32) does not move to right unlocking.In Fig. 6 (105), (106) are the bossy body that fixation is engaged with locking cover plate in Fig. 7, the assembling of this lock is used modular mode.

Because this lock pin is built-in, so, it can make in heavy metal plate or its dope layers such as leadings on the inside of lock box etc. Comprehensive prevent the detection to the groove (8) of blade such as X ray to unlock completely.

Pushing plate (14) in this lock, first being moved right when unlocking by its each blade of promotion to the effect of bottom point is：Every time All all blades are shifted onto right bottom point during unlocking, to prevent for a long time using groove (8) place that can detect blade later.This lock In the track of each part, fixation, connection etc. do not introduce, be defined in a manner of existing lock or machinery etc..In this lock Figure 13 top views, promote Piece (29) and (31) are all right on or below pushing plate (32) respectively, as long as (29) promote (32) to move to right, (31) can promote (32) return is moved to left just, pushing plate (38) is also such.In this lock Figure 13, blade (7) moves right the distance of A-B in Fig. 3 again, Its groove (8) just aligns with key tongue (1) and can unlocked, that is, a figures in Fig. 3, and b figures are the distance for moving BC again, and c schemes successively Again plus CD, d figure add DE again, and e figures add EF again again, then the vaned groove (8) of institute is all alignd with key tongue (1).

For this lock when for safe-guard door lock, with the lock shown in Figure 13, key rotation, which is unlocked, promotes unlocking angle different.Such as In Figure 13 front views, dotted line keyhole is unlocking bottom point position, and C points are to start to promote unlocking power plate (32) to move to right rising for unlocking Point.When needing to promote big dead bolt again by key for antitheft door, safety cabinet etc., A points can be set and moved to right to start pushing plate (32) The position of key point tongue (1), it is that key tongue (1) is unlocked to bottom point to B points, by B to dotted line key hole site to promote big dead bolt to unlock, Block body (40) now can be changed to as reclinate on the left of figure, so as to ahead of time disconnect keyhole now and blade.

The keyhole locked now is generally straight up, can be by the lock body right-hand member for the lock being used in Figure 18 on antitheft door Tilt down, so that keyhole is straight up, the stretching body (3) of key tongue (1) in Figure 18 three-dimensional exploded view is still turned to lock Block body (77) is unlocked.Because the rotation of this lock key and leaf abscission and turning to just is unlocked afterwards, groove on the key can be with Go to disappear.In order to prevent losing the later trouble of key, can by the information of key bit, as Fig. 4 key is a, b, c, d, e, a, b, C, or 1,2,3,4,5,1,2,3 etc. can represent the symbol such as letter, digital or well-regulated Chinese character of above- mentioned information and the model of lock Deng numbering, user is given together with key, so, after key is lost, there is provided above- mentioned information, just can easily copy Key.

Can be simultaneously plus the mode such as vibration, light during connection warning circuit in this lock.It can also be connected to simultaneously Its convenient other positions for controlling and checking, or as the switch for starting the connection of the circuits such as shooting, phone, mobile phone.This lock Figure 13 In have 8 blades, as existing lock, can there is the different numbers of blade and difference number as requested.

Lock described above can only anti-technology unlocking, introduce the method that prevents strength picking lock core again below and automatic change The function of key.

Figure 26 is the solid for promoting unlocking key tongue switch lock and promoting each blade to return to part driven by key axle (15) Exploded view, left side leads to the plan of each counterpart in figure.This figure is the improved technology of Fig. 9 and Figure 10 parts, and key axle can Arbitrarily to rotate, Fig. 9,10 introduction may be referred to.The initial point and stop of key rotary switch lock, figure are set in foregoing lock 9th, each part is shuts bottom point, unlocking initial point in 10, and key axle can not counterclockwise rotates again in Fig. 9.Described Figure 26 now The lock of introduction, the top that the sophisticated bossy body on the right side of piece (29) is promoted in Fig. 9 is also changed to the inclined-plane as following, piece will be promoted (31) the following of left groove is also changed to inclined-plane, and so, key band moving axis (15) just can rotate freely to any direction, so as to Promote unlocking power plate (32) side-to-side movement.Similarly the side on the right side of the promotion piece (36) in Figure 10 is also changed to oblique, makes key Drive and promote piece (35) (36) also can arbitrarily rotate, so as to pushing plate (38) side-to-side movement.When having more than general key intensity HHT higher high tensile twists key axle, and key bit not pair when, unlocking key tongue can not enter unlocking groove drawback lock.Now, unlocking power Plate (149) can be to left movement so that key can arbitrarily rotate.In other Figure 26, each blade will be promoted to return to what is resetted in Fig. 2 Flexure strip (4) is also changed to plate (177), and it is such as diagram shape downward that the power arm (2) of unlocking key tongue (1) in Fig. 1, which is changed, will be unlocked Power plate (32) is changed in Figure 26 (149) shape, between its vertical bossy body (147) and the power arm of unlocking key tongue (151) by Spring connect, so, unlocking power plate (147) when to left movement by spring pull unlocking key tongue (151) unlock, to Promote the power arm of unlocking key tongue (151) to move right by bossy body (148) during right motion to shut.Blade return spring piece in figure It is changed to after plate, promotes piece (142) and (144) the also difference with Figure 10 introductions.The top is the bolt plate (140) of outer connection, Positioned by key axle, stretched into by unlocking key tongue (151) in its right ports (141), and drive plate motion to realize switch lock, it is this Mode can be used (only lock side sometimes) in many examples.In the lock of actual figure 26 above introduction, only unlocking key tonguing enters Unlocked in unlocking groove a kind of this mode, can also be that the stretching body of unlocking key tongue turns out as dead bolt or is plate in this figure (140) positioned, be not connected with key axle, now, if thering is destructive power to become axle at key axle by the fixing axle of unlocking key tongue (151) Shape, damage will not also be unlocked.Bottom is lock interior plate (153), and it is act as such as (27) in Fig. 8.All parts of top Axle (15) upper end is stretched into successively, and is fixed in the top by elastic circlip, and the specific action process of this figure is explaining other originals Reason is together explained later.

Figure 27 is to introduce the three-dimensional exploded view for being used for promoting the knob (158) for changing key.In figure lock interior plate (153) with Figure 26 middle and lower parts plate (153) is same plate, and two, left side vertical plate (154) is the track fixed plate of plate (149) and (143), plate (149) stretched into the left end of (143) in two vertical plates (154).Hole (155) is the axis hole of key axle (15).Lower right side groove (168) track body hole is stretched out for unlocking key tongue (151).Knob (158) for change key line shaft, its arc bossy body (161) two sides are counterclockwise rotates bottom point shown in figure by the control of the vertical plate (162) fixed with plate (153), Its energy up time direction is rotated slightly larger than 180 °.Lower right side is revolving part (164), by its borehole jack on post (169), makes its upper right side Bossy body tip stretch into indicating positions in the figure at arc bossy body (170) place, so it will prevent knob (158) up time direction Rotation, it stretches out the groove of plate and clamps the upward stretching body (Figure 26 directions) of unlocking key tongue (151) to the left, so, when opening After lock, unlocking key tongue inwardly moves, drive revolving part (164) up time direction rotate, make its stretch out upwards body move right it is de- From (170), so as to which knob (158) can rotate, and it is set in arc during the entire process of knob (158) rotates to bottom point and protrudes Body (170) will all prevent (164) from returning.The right-hand member of post (160) is enclosed on the post being fixedly connected with lock interior plate (153), left end Lean against on knob (158) such as on the bossy body (159) of diagram shape, and post has the elastic force of inward direction, it act as making knob (158) will not autorotation.After knob (158) up time rotates to bottom point, post (160) leans against on the inside of bossy body (159) again Plane on, equally make it will not autorotation.The right-hand member of unlocking power plate (149) is fluted (150), and knob is as is noted in the figures Post between the bossy body (161) shown and (165) is stretched into groove (150).The lower part of knob (158) is cylinder, and cylinder (165) and (167) the two same diameters of part, the part between arc body (161) and cylinder (165) between (165) and (167) Part with straight warp, (165) partly by lock interior plate (153) fixation of such as figure, (167) of lower end are partly consolidated by lock outer side panel Fixed (with reference to lock panel (19) in figure 6, and (19) are introduced in Figure 13), the operating principle of this diagram is introduced again later.

Figure 28 be knob (158) and this lock key axle (15) of the replacing key of Figure 27 introductions, lock blade (171), (178), unlocking key tongue (151), blade return to power plate (145), the plan of flexure strip (172) combination, are Figure 26 and Figure 27 The simple view in direction is looked up, for the positive direction of lock.Lock blade is divided into two parts, upper part (178) up and down in this figure has The downward tooth (174) of this lock unlocking groove (173) and right side, lower part are its powered part, and right-hand member has upward tooth (175), right-hand member is fluted to the right (176), and the post (166) in Figure 27 on knob between (167) and (165) part stretches into all leaves In the groove of piece.Low order end, to make two part blades be connected firmly, draws 3 to promote the plate (177) that blade returns in this figure Tooth is connected (alterable), and there are 7 teeth upper part lower right side.This lock unlocking key tongue (151) lower end is pointed, unlocking groove (173) there are 4 teeth on the left of, right side there are 5 teeth.Unlocking key tongue (151) is located on the right side of unlocking groove (173) the 1st in Figure 28 a The top of tooth, 3, the left side tooth in 7 teeth of 3 tooth connections and upper part of lower part blade (171) are mutually connected.Work as leaf Piece (171) promoted to the right by key 1 tooth pitch from when, it is interior and unlock that unlocking key tongue (151) can just enter unlocking groove (173). In Figure 28 b, 3 teeth of lower part are mutually connected with 3 teeth on the right side of upper part, and at this moment unlocking key tongue (151) is located at On upper part blade above the tooth of low order end, now blade promoted to the right by key 5 teeth apart from when, unlocking key tongue (151) It can enter in unlocking groove (173) and unlock.Similarly Figure 28 a middle and upper parts part (178) is often moved to the left 1 tooth, then groove of unlocking Also it is moved to the left 1 tooth, must also the do more physical exercises to the right again distance of 1 tooth of key just can enter unlocking key tongue (151) to unlock Groove (173) drawback lock, that is, converted the key bit corresponding to the blade.Conversion between them is to pass through turn knob (158) realize, when knob (158) up time direction in Figure 27 rotates, the diameter between cylinder (165) and (167) part Less cylinder, driving all blades (171) right-hand member to move downward (Figure 28 directions) makes the two disengaging, and setting rotation is slightly larger than 180 ° of purpose is bright fresh to find out that knob (158) upper end (Figure 27 directions) groove direction is become from lock outside (the door back side) Change, become for incline direction, (vertically rotating front position for Figure 27, it is oblique to rotate to after bottom point).When knob (158) inverse time side To return, two part blades again it is engaged together.In one row's blade (in Figure 13 be 8), (178) of blade partly and (171) be partly engaged in different teeth so that the number of teeth of unlocking groove to unlocking key tongue into certain combination, and the tooth of key with When corresponding blades arrangement gets up, the unlocking groove part of all blades is set to be in the underface of unlocking key tongue and can unlock.

Figure 26, the switch lock of 27,28 locks, the action process for changing key is described below：It is partly respectively in each figure Unlocking initial point, bottom point state is shut, wherein (142), (144), (146), the A points of (152) is at origin, key can be to any Direction rotates freely.In Figure 28, key up time direction rotates to be unlocking direction, the inverse time direction rotate, will not unlock (pick-proof Lock core function).During unlocking, insert a key into keyhole, up time direction (Figure 28) rotation drives key axle (15) rotation (figure 26th, 27 be inverse time direction), drive and promote piece (142), (144), (146), (152) to rotate together, wherein piece (146) is promoted, (152) without promotion unlocking power plate (149) motion between A-B.A points are moved to promoting the B points of piece (142) and (144) During opening position, promote piece (144) to decontrol, promote piece (142) pushing plate (143) to move right (plate in the plate and Figure 10 (38) equally, all it is to promote each blade to return), blade Returning plate inverse time direction (Figure 28 directions) is rotationally disengaged out each blade Certain distance (length that the distance should be greater than pushing plate (14) and most long key bit promotes each blade to move to right), is at the same time pushed away Dynamic plate (14) also promotes each blade to move right to right bottom point.Key continues to rotate, when the C points fortune for promoting piece (142) and (144) When moving to respective A points opening position, promote piece (142) to decontrol, promote piece (144) and pushing plate (143) is back to left bottom point, with this Meanwhile pushing plate (14) is also moved and detaches each blade.Then key continues to rotate, and makes the D on promotion piece (142) and (144) Point moves to respective A points opening position, promotes piece (144) relieving, promotion piece (142) and pushing plate (143) extremely right summit therebetween, At the same time, each tooth of key also promotes each self-corresponding blade to move right, and now key is rotated to horizontality.This Afterwards, no longer pushing plate (143) is moved during the E points of promotion piece (142), (144) move to A point opening positions.Hereafter, key Spoon continues to rotate, and when key moves to Figure 28 B point opening positions, promotes the B points of piece (146) and (152) to also move into Figure 26 In respective A points position.Key is further continued for rotating, and promotion piece (146) and the C points of (152) is moved to A points position, BC is oblique Side promotes unlocking power plate (149), and to left movement, (plate is all to promote to unlock with the unlocking power plate (32) in Fig. 9, different Be that plate (32) is to push directly on the power arm (2) of unlocking key tongue, and plate (149) is to pull unlocking key tongue (151) by spring And unlock), unlocking key tongue (151) up time direction (Figure 28) rotation is pulled by spring, its right-hand member is extended downwardly from body entrance and opens Lock crossbeam (173) drawback lock.Key continues to rotate, and makes promotion piece (146) and the D points of (152) to A points position, in C-D stage In, plate (143) and (149) equal without motion, the purpose for designing larger angle are：It is strong due to there is no key switch to lock in this lock Power terminal, simply key go to about equal position and just unlock, when for antitheft door (Figure 18), the process for promote body (78) The process for promoting big dead bolt (67) to unlock.This elastomer can also be put in A points position, be fixed on lock body, promote piece (146) Or a V-type groove is set at the D points of (152), when being rotated at D points to the elastic body position, the elastomer enters above-mentioned V-groove In, by key it is bright it is fresh feel unlocked, without prevent key continue to rotate.So far this lock unlocking process is completed. Now, movable block body (164) is stretched out body by the drive of left end unlocking key tongue (151), up time direction (Figure 27) rotation, its upper right side Stretch out that knob (158) is convex to appear (170) outside

Introduce the action process for changing key again below：By can be seen that in Figure 27, the knob (158) of key is changed in lock The back side, now, (Figure 27 directions) turn knob (158) arrive bottom point clockwise, now can not be followed by by block body (162) stop Continuous rotation, in this process, block body post (160) inverse time direction is rotated, and knob (158) is rotated, and bottom is screwed into knob (158) After point, block body post (160) is kept off in the flat edge of back again, to prevent it from rotating automatically.

In Figure 28 knob (158) be the inverse time direction rotate, make (166) of small diameter partly in knob post (167) and (165) rotated to below by top under the drive of part, so as to also drive the right-hand member of each blade (171) part also to move downward One segment distance, make to depart from occlusion between the tooth (175) of blade (171) part and the tooth (174) of blade (178) part.Now, Unlocking key tongue (151) is engaged with unlocking groove (173), and (178) of blade can not partly move again.In above-mentioned replacing key After spoon knob (158) rotation, the cylinder part on its post between arc bossy body (161) and cylinder (165), such as cylinder Cylinder part between body (165) and (167), he also drives the right-hand member of unlocking push pedal (149) to move downward (Figure 28 side To), Figure 26 and 27 is inward direction, the power arm of promotion unlocking key tongue (151) is moved right the unlocking power plate shut (149) body protruding upward (148) on, also inwardly move and be separated from the tracks of unlocking key tongue (151) power arm, this Sample, unlocking key tongue (151) would not be promoted again when unlocking power plate (148) moves right again.

After the knob (158) that key is changed in rotation：First, it is further continued for rotating key, drives key axle (15) rotation, push away It is dynamic to promote piece (142), (144), (146), (152) to continue to rotate.Piece (142) and (144) is promoted to return such as origin position in figure Put, promote piece (142) to decontrol therebetween, promote piece (144) to promote blade return power plate (143) to return to left summit again, pull again Returning plate (177), which moves to left, to return back to top a little, promotes all blades (171) to return to left summit again therebetween.Promote piece (146) and (152) Also return to such as the origin position in figure, promote piece (152) to decontrol, promote piece (146) promote again unlocking power plate (149) move to right to Right summit, during which due to changing key knob (158) rotation so that unlocking power plate (149) inwardly motion (Figure 26 directions), make Bossy body (148) is promoted to stretch out the tracks of unlocking key tongue (151), unlocking key tongue (151) does not move, moreover, The knob of key is changed after rotation, the post (158) of large semi-circular protrudes above body (170) and also prevented in movable block body (164) Upper right side right side, direction rotates return when preventing it from another mistake, this allow for have rotated change key knob after, open Locking key tongue (151) will always be in unlocking condition.2nd, after above-mentioned unlocking, key can also return again to, until returning former Point, the process are the inverse process of above-mentioned unlocking process.

After key returns to origin, key is extracted, then the new key insertion keyhole that will be changed, revolve clockwise Turn on and be locked to bottom point, this process as above-mentioned unlocking process, except that, one, due to blade (171) and blade The tooth of (178) two part occlusions disengages, so key is to have promoted following (171) part.2nd, due to unlocking push pedal (149) body (148) is promoted also also not moved departing from the track of unlocking key tongue (151) power arm, unlocking key tongue (151) on, It is still within unlocking condition.It is above-mentioned again with new key unlocking to bottom point after, then knob (158) return of key will be changed To such as Figure 27 present positions, then Figure 26, all parts return to origin again in 27,28, and blade (171) and (178) two parts are stung again It is combined that (because new key bit is changed, the occlusion between the tooth (174) of blade and (175) is changed, its mesh Be to have reached after new key combines with blade (171) and (178) to be in unlocking condition).Unlocking power plate (149), which protrudes above, to be pushed away Kinetoplast (148) is also returned to the left side of unlocking key tongue (151) power arm.Then it is further continued for rotating key to shutting in origin such as figure Position or key is back to origin again, each action therebetween for unlocking action inverse process, so far, this lock replacing key Spoon action is completed.

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

Sequence number (156) is the track axis hole of unlocking key tongue (151) in Figure 27.(157) it is lock panel fixing hole.(163) it is Lock body fixing post hole.(132) it is lock side plate.

Figure 28 a, b are the two states with some, therefore without mark sequence number in b figures.

Figure 26, in 27,28, before unlocking power plate does not move to left unlocking, between the tooth of unlocking key tongue and blade (178) Still lock is the same as the aforementioned, there is certain gap between them, so as to be unable to technology detection, promote unlocking key tongue (151) to During lower motion, its tip blade that occlusion residence has first, it is allowed to move again, then, is further continued for unlocking action.In this lock As long as unlocking condition will not then be entered by having a blade not move to left.Actually this lock is three kinds of status locks, to promote piece (152) to be Example, key rotate, before its B point moves to A points for cannot unlocking condition, be unlocking when C points are moved at A points Process, D points move to A points as process after unlocking, and into figure, state is to shut state.

In this lock, the key tongue part unlocked into unlocking groove should be：Using unlocking key tongue rotary shaft as the center of circle, with the center of circle Some to key tongue for the circular arc of radius.

Figure 26,27,28 introduce the part blades of lock two between occlusion, reality in key need not change many times, this Sample, (171) part of blade only set a tooth, and (178) partly set two teeth, can by the bigger of the two design, occlusion it is deeper, It is more firm.

Figure 26,27,28 locks introduced, due to the unlocking groove unlocking one kind side for only having unlocking key tongue (151) to enter blade Formula, so, should be by Figure 14, the application mode of the padlock in 15, it is changed to pin right side, Figure 15 opening should be on right side.

Because antitheft door has inside and outside two locks, so, should be by above and below two knobs for changing key or left-right situs is in door The back side of lock, from behind the door in terms of face：The knob that face outdoors is locked is connected to face behind the door by gear, to change key respectively.

Due to this lock can not easily technology unlocking, for make after key is lost can be timely to client with renewing Key, client can be together given for simple name of object easy to remember etc. by the information of key bit or by the information setting, with Make client say tooth information or name in time with changing key.

This lock each part during for door, antitheft door in the way of dress should be existing door, to facilitate by dress.Such as Figure 18,19, Button (83) should be in 20：A button that can be removed separately is set, (83) are promoted by the button.
