Detailed description of the invention
Embodiment one:
Shown in composition graphs 1 and Fig. 2, the lock core that the present embodiment provides, comprises lock core shell 1, turns core 2, clutch-plate 3, clutch-plate spring 4, iron core 5, iron core spring 6, lock pin 7, lock pin spring 8 and location jump ring 9.
As shown in Figure 1, turn core 2 and be installed in rotation in the inner chamber 101 of lock core shell 1, lock core shell 1 upper-center offers keyhole 102, and location jump ring 9 limits and turns core 2 axial location in lock core shell 1.Turning core 2 lower end is lockset switching controlling part 201, and lockset switching controlling part 201 stretches out the lower end of lock core shell 1, unblocks to lockset for turning when core 2 rotates.Turn core 2 sidewall longitudinally to offer four clutch-plate chutes, 202, four clutch-plates 3 and can be arranged at longitudinal sliding respectively in clutch-plate chute 202.Four clutch-plate chute 202 lower ends are provided with shutoff pin 203, four clutch-plate springs 4 and are installed in bottom in four clutch-plate chutes 202 respectively, and shutoff pin 203 is supported in clutch-plate spring 4 lower end, and clutch-plate 3 is supported in upper end.
Clutch-plate 3 arranged outside has two grooves 301, lock core shell 1 inwall is provided with and can be the ring rib 103 that described groove 301 provides rotation guiding, ring rib 103 is provided with the middle fracture 1031 (shown in composition graphs 2) for clutch-plate 3 longitudinal sliding motion, the position offered of middle fracture 1031 is corresponding with the position turned when core 2 and clutch-plate 3 are in blocking.Shown in composition graphs 3, when unlock key 100 inserts keyhole 102, the unblock tooth 111 of unlock key 100 promotes clutch-plate 3 downwards, when clutch-plate 3 longitudinal sliding motion is to ring rib 103 sustained height with lock core shell 1 inwall of upper recess thereof groove 301, turn core 2 and clutch-plate 3 can annularly rotate by raised line 103; When extracting unlock key, clutch-plate spring 4 is clutch-plate 3 upwardly, when clutch-plate 3 longitudinal sliding motion to upper recess thereof groove 301 misplaces with the ring rib 103 of lock core shell 1 inwall, turns core 2 and clutch-plate 3 cannot annularly rotate by raised line 103.
Continue see Fig. 1, the position turning the corresponding keyhole 102 in core 2 top longitudinally offers iron core hole 204, and iron core 5 can be assemblied in iron core hole 204 with longitudinal sliding, and iron core 5 supported downwards by iron core spring 6.Lockpin hole 205 is laterally offered in side, lower end, iron core hole 204, and lock pin 7 can laterally fit slidably in lockpin hole 205, and lock pin spring 8 outwards supports lock pin 7.Lock core shell 1 inwall side offers lock pin draw-in groove 104, and lock pin 7 embeds in lock pin draw-in groove 104 or is separated with it.Shown in composition graphs 3, unlock key 100 has permanent magnet, during unblock, the active force that iron core 5 overcomes iron core spring 6 is picked up, in iron core hole 204, the space retreated for lock pin 7 is vacated in lower end, lock pin 7 is retracted by the active force overcoming lock pin spring 8 during lock core shell 1 inner wall pressure, turns core 2 and clutch-plate 3 can annularly rotate by raised line 103; During locking, lock pin 7 stretches out by the active force of lock pin spring 8 and embeds in the lock pin draw-in groove 104 of lock core shell 1 inwall, iron core 5 moves to lower end in iron core hole 204 under the effect of iron core spring 6 simultaneously, block the space that lock pin 7 retreats, now turn core 2 and clutch-plate 3 cannot annularly rotate by raised line 103.
Therefore the magnetic control lock core of above-mentioned gradable unblock has two ore control function, one is by clutch-plate 3 matching mechanism with ring rib 103, and two is the matching mechanism of lock pin 7 and lock pin draw-in groove 104.In addition, can realize classification unblock, namely different keys by arranging plural groove 301 on clutch-plate 3, its distance promoting clutch-plate 3 length travel is different, as long as make certain groove 301 on clutch-plate 3 and ring rib 103 contraposition, just can unblock.And, the number of the clutch-plate 3 in the present embodiment is at least one, Duo Geshi, and the position of the groove 301 that each clutch-plate 3 is arranged can be the same or different, time different, can be mated by the depth of the corresponding unblock tooth 111 arranging unlock key 100.Multiple ring rib 103 can certainly be set, then the position of groove 301 on respective design clutch-plate 3, as long as institute fluted 301 all can contrapositions ring rib 103, just can unblock, the theftproof performance of lock core can be improved like this.
Embodiment two:
Embodiment two is with the difference of embodiment one: two grooves of clutch-plate arranged outside are substituted by two projections, and the ring rib that lock core shell inwall is arranged is substituted by cannelure, arranges the longitudinal guide groove crossing with cannelure at lock core shell inwall simultaneously.The position offered of longitudinal guide groove is corresponding with the position turned when core and clutch-plate are in blocking.Longitudinal guide groove for the protruding longitudinal sliding motion of clutch-plate arranged outside, when the projection that cannelure is used for clutch-plate arranged outside is positioned at this height, annularly groove rotation.
Above-described embodiment is only fully open and unrestricted the present invention, and the present invention of every foundation innovates purport and replaces and increase and decrease without creative work and obtainable equivalence techniques feature, all should belong to covering scope of the present invention.
