Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.

As shown in Figure 1: adjustment dish 3 is mainly used in and active combination disk 8 matches, and its centre bore 4 is enclosed within on the lock core 2, rotates together with lock core 2.In addition, also have a breach 5 on the adjustment dish 3, along with the rotation of adjustment dish, initiatively the

projection

14 or 24 on the active pellet shot from a

slingshot

12 or 13 in the combination disk 8 can pass this

breach.Projection

14 and 24 both can be in the top (claiming that initiatively pellet shot from a slingshot is positioned at upper limit position this moment) of breach, also can be in the below (claiming that initiatively pellet shot from a slingshot is positioned at the lower position this moment) of breach.As Fig. 1, when unlocking condition, the below that projection 14 is positioned at breach 5 i.e. the inside of adjustment dish, 24 outsides that are positioned at the adjustment dish of projection.In addition, the side of centre bore 4 has an aperture, and a pellet shot from a slingshot 6 that connects together with spring is housed in the hole, initiatively pellet shot from a

slingshot

12 and 13 move up and down by pellet shot from a slingshot 6 and decide.In addition, also have a block 7 on the adjustment dish 3, after lock core revolves and turns around, this block 7 promote flange 15 on combination disk 8 initiatively cross interlock sheet 20 revolve turn around after, blocked by the interlock sheet again, stop the initiatively continuation rotation of combination disk.

Initiatively combination disk 8 is another main open and close controlling mechanisms except that the adjustment dish, and small one and large one two centre bores are arranged, and big centre bore 9 is enclosed within on the adjustment dish 3, and lock core 2 extends in the little centre bore 10.Spring 11 and active pellet shot from a

slingshot

12 and 13 are equipped with in space between the side of big centre bore 9 and active combination disk 8, and spring 11 is positioned at the top in space and is connected with the active pellet shot from a slingshot.Initiatively pellet shot from a slingshot divides large and small two kinds, and shape is similar to " L " shape, on it is long-armed a projection is arranged respectively, the just big initiatively height of the little active pellet shot from a slingshot 13 of aspect ratio of the galianconism of pellet shot from a slingshot 12.When the projection 14 of active pellet shot from a slingshot 12 is in breach 5 belows, initiatively the galianconism of pellet shot from a slingshot 12 is all in the active combination disk, when projection 14 is in breach 5 tops, its galianconism part is in the active combination disk, another part promotes driven pellet shot from a slingshot 17 and puts in the driven combination disk, so initiatively the galianconism of pellet shot from a slingshot 12 is stuck within two combination disk, initiatively pellet shot from a slingshot 12 is in clamped condition, the active combination disk can't be rotated, equally, when initiatively the projection 24 of pellet shot from a slingshot 13 was in breach 5 belows, along with the whereabouts of active pellet shot from a slingshot 13, the driven pellet shot from a slingshot 17 that is in contact with it put in the belled position of active combination disk and driven combination disk, the long-armed part of driven pellet shot from a slingshot 17 is in driven combination disk, another part is in the active combination disk, and driven pellet shot from a slingshot 17 is in clamped condition, and the active combination disk can't be rotated.

Driven combination disk 16 also is main open and close controlling mechanism, works with the active combination disk, and structure is with initiatively combination disk is similar, and it is enclosed within on the active combination disk.The number of the driven pellet shot from a slingshot 17 on the driven combination disk 16 is with initiatively pellet shot from a slingshot is identical, and form also is similar to " L " shape, but the size of driven pellet shot from a slingshot is the same.The galianconism of driven pellet shot from a slingshot 17 contacts with the upper surface of the galianconism of pellet shot from a slingshot initiatively, passes through the spring 18 that connect, moves up and down with the active pellet shot from a slingshot.

For getting rid of foreign matter in the lockhole, lockhole penetrates lock core.One passage 19 that is connected with lockhole is arranged in the centre of active combination disk, for safety, also fix a removable hollow device near the lock body of passage 19, foreign matter can be fallen into this device through passage in the lockhole.As shown in Figure 2: interlock sheet 20 is one the slide plate of curved groove to be arranged, and two steady pins are arranged in the groove, is fixed on the lock body, and interlock sheet 20 horizontally slips by flange 15, rises to hinder a lock core and make unnecessary rotary action.

Initiatively pellet shot from a slingshot promotes pellet shot from a slingshot 6 by key and moves up and down, and pushes away before the key, move on the pellet shot from a slingshot 6, and the key post-tensioning, pellet shot from a slingshot 6 glides.For this reason, the lock core upper surface has an elongate slots, and outer tapered end inner surface is fixed a pin, and lock core and key can front and back pulling one segment distances like this.

Big pellet shot from a slingshot on the active combination disk, the number of little pellet shot from a slingshot and sequence of positions thereof are arbitrarily, but have only the big pellet shot from a slingshot of working as to be in the lower position, and the active combination disk is rotated smoothly, reach the purpose of unblanking.No matter be the big pellet shot from a slingshot or the driven pellet shot from a slingshot of submissile contact, as long as there is one to be in clamped condition, initiatively combination disk just can not be rotated.

The utility model can be on active combination disk and driven combination disk 4 of symmetric arrays initiatively pellet shot from a slingshot and driven pellet shot from a slingshot, initiatively pellet shot from a slingshot is two big two little, it is---greatly---little---little that sequence of positions be big.When blocking, big initiatively pellet shot from a slingshot is positioned at upper limit position, and little active pellet shot from a slingshot is positioned at the lower position, when pellet shot from a slingshot 6 faces big active pellet shot from a slingshot 12, the key post-tensioning, pellet shot from a slingshot 6 is glided, and initiatively pellet shot from a slingshot 12 drops down onto the lower position simultaneously, lock core Rotate 180 °, at this moment, pellet shot from a slingshot 6 faces little active pellet shot from a slingshot 13, pushes away before the key pellet shot from a slingshot 6 is risen, and promoting initiatively, pellet shot from a slingshot 13 rises to upper limit position.During 90 ° of lock core revolutions, preceding pushing away or the post-tensioning key can be adjusted the initiatively upper-lower position of pellet shot from a slingshot, makes big active pellet shot from a slingshot be in the lower position, and little active pellet shot from a slingshot is in upper limit position, just can unblank.After lock core turned over a circle, the flange 15 that the block 7 on the adjustment dish promotes on the active combination disk was crossed interlock sheet 20, revolved the back flange 15 that turns around again and was blocked by interlock sheet 20.Initiatively in the combination disk rotary course, the sheet 21 that pulls out on it is stirred the driver blade 22 of dead bolt rotating mechanism and is made dead bolt 23 open and close lock.
