Detailed description of the invention
At Fig. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, in 13, the utility model relates to a kind of lock & key technical field, more specifically to a kind of blade lock pin and key, comprise: lock body 1, sealing bolt 2, spring 3, lock pearl 4, side column 5, installing hole 6, thumb wheel 7, side column groove 8 in lock gall, side column groove 9 in lock body, inclined-plane, lock gall keyhole front end 10, push away post 11, slide block 12, collar 13, leaf spring 14, blade 15, lock gall 16 and key 17, the lock gall vane hole of this device is built with three blades, be provided with three groups of tartars on the key, the key back side is provided with two straight-line grooves, the front end of lock gall keyhole is provided with inclined-plane, breach blade playing locking action is U-shaped, with the vane hole of lock gall existing on market built with two blades and on blade breach be the lock core ratio of V-type, theftproof performance is good.
The utility model compares with common blade lock core, has the following advantages:
A. overlap not open: key 17 has three groups of independently tartars, teeth form shape is ever-changing, and the shape of key 17 is also different with the key of existing lockset, use the lock core of the key cover not format device of other factory key or an other lock.
B. dial not open: in lock gall 16, be provided with multiple vane hole 16-3, each vane hole 16-3 is built with three blades, protruding 16-2 is provided with in keyhole, lateral clearance on each blade 15 and between the projection that acts on of key 17 is less, and due to the stop of the protruding 16-2 in key 17 hole, remaining space is very little, unlocking tool is difficult to action in lock core, even if insert unlocking tool to stir certain sheet blade in lock gall 16, also another sheet or another several blades can be driven, lobus sinister sheet 15-1 and lobus dexter sheet 15-3 is U-shaped with breach I 15-4 of side column effect, namely the angle of limit I 15-4-1 and limit II 15-4-2 is 90 degree, the angle of limit II 15-4-2 and limit III 15-4-3 is 90 degree, gap width on blade is just slightly larger than the width of side column 5, as long as blade breach does not have complete matching, side column does not just fall, lock core just can not be opened, so operation technique method for unlocking dials the lock core of not format device.
C. turn round not open: in lock gall 16, lock gall keyhole 16-1 cross section is M shape, after filling blade 15, the remaining space in the lock gall keyhole 16-1 of lock gall 16 is very little, the very thin tool that goes into operation by force can only be inserted, firmly twisting go into operation by force tool time, instrument is twisted off, and turns round the lock core of not format device.
D. prize not open: inclined-plane 10 is processed in the keyhole front end of lock gall 16, make picklock can not find effective fulcrum, use picklock to prize the lock core of not format device.
E. bore not open, inclined-plane 10 is processed in the keyhole front end of lock gall 16, and the drill bit of electric drill is difficult to boring on inclined-plane, bores and then slips in keyhole, bores less than position crucial in lock core, so bore the lock core of not format device.
Lock core operating principle: when inserting the key 17 of this lock core from one end of lock core, tartar on key 17 promotes blade 15 and moves, after key 17 is inserted into enable possition, breach alignment in this end lock gall 16 on whole blade 15, form a straight trough, in the lock gall that side column 5 all enters lock gall 16 under the pressure of spring 3 and lock pearl 4 in side column groove 8, lock gall 16 can rotate, and lock core is opened, when outwards transfering to key 17, curved groove on key 17 drags the protruding 15-7 with key contact on Leaf, make Leaf 15-2 action, on Leaf 15-2, limit IV 15-6-1 of breach II 15-6 is by side column 5 jack-up, because at the bottom of the tooth of key left tartar 17-1 and right tartar 17-3,17-4 is wider, front vane 15-1 and rear blade 15-3 does not move, until after the complete jack-up of side column 5, front vane 15-1 and rear blade 15-3 is the action by the thrust of key 17 upper left tartar 17-1 and right tartar 17-3, side column 5 lived by frame, prevent side column 5 from falling after rise, in the lock body of the part insertion lock body 1 of side column 5 in side column groove 9, lock gall 16 can not rotate, lock core locks.
Certain above-mentioned explanation is not limitation of the utility model; the utility model is also not limited only to above-mentioned citing; the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also belong to protection domain of the present utility model.
