The specific embodiment
As shown in the figure: lock core 5 is arranged in lock housing 1, axial lockhole 11 is arranged in lock core 5, shell hole radially is set on lock housing 1 and lock core 5, place roller 6 and spring 19 in the shell hole, utilizing latch 15 hinged locking plates 8 down under the location on the lock core 5, latch 13 hinged upper collets 7 on the correspondence position utilization location of lock housing 1, position corresponding to upper collet 7 on lock core 5 is provided with annular groove 9, the one side of the driving lever 20 on an end that has a spring 19 at least and the upper collet 7 contacts, have at least a roller 6 to contact with the another side of driving lever 20, the opposite side of upper collet 7 is a draw-in groove 21, on the locking plate 8 buckle 22 that can snap in this draw-in groove 21 is being set down, opposite side at following locking plate 8 is provided with block 23, connection base plate 4 below lock housing 1, and between base plate 4 and lock housing 1, lower gasket 2 is set, 3, position corresponding to shell hole on base plate 4 is provided with chute 26, the slide block 24 that placement can be stirred by block 23 in chute 26, outer end at slide block 24 and chute 26 is provided with the contact that can be in contact with one another respectively, in the contact of chute 26 and any position of lock housing 1 or base plate 4 draw lead respectively and be connected with alarm 18.
During use, key 17 is inserted in the lockhole 11, and the four edges on the key 17 is inserted in the corresponding groove respectively, in the process of inserting, tooth on the key 17 reaches two rollers 6, following locking plate 7,8 progressively eject lock core 5, when key 17 moves down when putting in place, key 17 forces roller 6 to withstand upper collet 7 and reaches locking plate 8 down, driving lever 20 on the upper collet 7 is embedded in the annular groove 9, the draw-in groove 21 that buckle 22 on the following locking plate 8 embeds on the upper collet 7, the push rod 25 of the other end just in time is positioned at the inner edge of Upper gasket 7 on the following locking plate 8, at this moment just can key 17, and drive lock core 5 and rotate together.If in opening process, error is arranged slightly, so, driving lever 20 on the upper collet 7 just can't enter in the annular groove 9, be stuck in the shell hole, lock core 5 can't be rotated, the buckle 22 on the following locking plate 8 also can't snap in the draw-in groove 21 on the upper collet 7, and the block on the following locking plate 8 23 can promote slide block 24 and move in chute 26, contact on the slide block 24 is contacted with being arranged at base plate 4 upper contacts, circuit turn-on at this moment, alarm 18 sends chimes of doom, lock is lockable, can't unblank, so this device has extraordinary theftproof performance, at ordinary times, slide block 24 is under the effect of spring 27, and the contact on contact on the slide block and the chute 26 is separated from each other.
On lock core 5, utilize dead bolt Fixed latches 14 to connect dead bolt.So that dead bolt and lock core are linked together, when rotational lock core, drive dead bolt and rotate, lock is opened the most at last.The transverse shape of lockhole 11 is cross, so that adopt cross key 17, thus improve the theftproof performance of lock.
Chute on the inner edge setting of Upper gasket 2 and the 26 corresponding grooves 28 of the chute on the base plate 4, the inner edge setting of lower gasket 3 and base plate 4 is 26 corresponding, but the locating slot 29 narrower than the width of chute 26 so that locking plate slides in groove.
Originally be locked in when opening, must adopt private key, the cross section of this key 17 is cross, on 4 limits of cross key tooth is set respectively, and the afterbody of key 17 is a handle 16, so that pinch key with hand, at the head of key 17, the distance on the end on every limit and key top is all inequality, and the head of these different distance has also constituted tooth on the key, during use, cross key is inserted in the cross lockhole.Screw hole and the screw of among the figure 12 for being used for lower gasket on the lock housing 12,3 and base plate 4 are linked together.
When this lock can't be opened, can utilize specific process to carry out technical opening by the manufacturer of lock.
