[specific embodiment]

As shown in Figure 1, a kind of AB multifunctional vane lock, it comprises lock housing 1 and lock gall 2, lock gall 2 is provided with bumper bar lifting groove 6, be provided with bumper bar 61 in the bumper bar lifting groove 6, described lock gall is provided with vane hole 4, is provided with the vane group 30 that is comprised of multi-disc blade 3 in the vane hole 4, the upper end of described every blade 3 is provided with draw-in groove 32 on the blade that snaps in for bumper bar 61, and key band moving vane 3 transverse shiftings also make draw-in groove 32 on the blade of multi-disc blade 3 upper ends line up a groove 321 that can fall into for bumper bar.Described every blade 3 is provided with the blade endoporus 31 that interts for key, is provided with the blade fixture block 311 that cooperates with key in the described blade endoporus 31, and described lock gall 2 also is provided with the blade locking device 5 that the partial blade in the vane group 30 is carried out disposable locking.Blade locking device 5 can make above-mentioned partial blade be fixed on a permanent position, and makes draw-in groove 32 on the blade of above-mentioned partial blade line up a groove 321 that can fall into for bumper bar.The lock slots that communicates with vane hole 51 that the inboard that described blade locking device 5 is included in lock gall 2 has, be provided with the locking piece 52 that can in lock slots, move in the lock slots 51, be provided with disposable lock stator 53 between locking piece 52 and the lock housing 1, the lower end of above-mentioned partial blade is provided with the blade lock location 32 that cooperates with locking piece 52.

Such as Fig. 2, Fig. 3, shown in Figure 4, locking piece 52 comprises locking piece body 521, and the upper end of locking piece body 521 is provided with sticking department 522 and avoiding area 523, and the lower end of locking piece body 521 is provided with the ejection part 524 that cooperates with disposable lock stator 53.Sticking department 522 is boss 522A in the present embodiment, and avoiding area 523 is groove 523A; Ejection part 524 is lower protruding block 524A; Blade lock location 32 is blade low groove 32A.

The structure of sticking department 522 of the present utility model can also be to be a projection or push rod (not shown), and the blade lock location 32 of matching with it this moment is a shrinkage pool.

The structure of sticking department 522 of the present utility model can also be to be a groove (not shown), and the blade lock location 32 of matching with it this moment is a projection.

Lock core inboard in the lock housing of the present utility model also is provided with tail cover (not shown), and bumper bar 61 cooperates to realize unlocking action by a driving member (not shown) with the tail cover; Perhaps the tail cover is made integrative-structure with lock core of the present utility model.

Such as Fig. 1, Fig. 8, Fig. 9, Figure 10 shows, the phase-locked key that cooperates of a kind of and above-mentioned AB multifunctional vane, what the one side of the front end of described key 100 was provided with the locking piece 52 of dodging the blade locking device dodges position 101, dodging position 101 can be a concave station 101A, key to dodge the position 101 can also be a straight trough 101B, when key inserts the blade endoporus, concave station 101A can avoid locking piece 52, at this moment, partial blade is owing to be subject to the locking of the locking piece 52 of blade locking device 5, make draw-in groove 32 on the blade of blocked partial blade line up a groove 321 that can fall into for bumper bar, key can be with the movable lock core rotation to realize unblanking smoothly, the rear end of key 100 also is provided with normal key groove 102, other blade in normal key groove 102 and the vane group 30 forms, can be with the moving vane transverse shifting, and make draw-in groove 32 on the blade of its blade upper end line up a groove 321 that can fall into for bumper bar.

Wherein the length of locking piece 52 matches with the length of dodging position 101, that is to say that the length of locking piece 52 equals the length of concave station 101A, and the length of locking piece 52 equals the length of straight trough 101B.

The phase-locked B key that cooperates of a kind of and above-mentioned AB multifunctional vane, the one side of the front end of described B key 200 is provided with the unlocking structure 201 that the blade locking device is carried out release, and unlocking structure 201 can be a key 201A who cooperates with blade fixture block 311.Key 201A is the correct valid key groove of unblanking of this lock core.During at this moment with B key blade endoporus, key 201A and blade lock location 32 namely blade low groove 32A cooperates, drive blocked partial blade transverse shifting, promote the sticking department 522 of locking piece 52 behind the blocked partial blade transverse shifting, thereby ejection locking piece 52 moves down, and extruding disposable lock stator 53, make locking piece 52 and blocked partial blade remove clip, and making draw-in groove 32 on the blade of blocked partial blade line up a groove 321 that can fall into for bumper bar, key can be with the movable lock core rotation to realize unblanking smoothly.Disposable lock stator 53 is to adopt the material such as aluminium to laminate in the utility model, disposable lock stator 53 can't restore after being extruded and producing distortion, just ejection locking piece 52 is located 32 namely blade low groove 32A formation clips with the blade lock of partial blade lower end again, at this moment, because key does not have to arrange the key 201A that cooperates with blade fixture block 311, also just can't insert again in the partial blade that unlocks, also just make key can not drive draw-in groove 32 on the blade of partial blade and line up a groove 321 that can fall into for bumper bar, bumper bar can not fall into groove 321, also just can not realize unlocking action.
