The specific embodiment

Each parts detail of accompanying drawing is as follows: A001 is lock core body, and A002 is the epimere lock core, and A003 is the lock core Connection Card, and A004 is the lock core hypomere, and A005 is card, and A006 is bottom.

The utility model as shown in Figure 1 comprises key A007 and lock core A002, and lock core A002 is positioned in lock core body A001, and described lock core comprises upper lock core A002 and lower lock core A004, and the structure of epimere lock core A002 is as shown in accompanying drawing 6,7,8.

As shown in accompanying drawing 4 and accompanying drawing 5, described upper lock core A002 lower end is connected with the lock core Connection Card A003 along the slippage of lock core axis, and described lock core Connection Card A003 has the groove that matches with key, is driven by key when key inserts and rotates; Circumferencial direction at lock core Connection Card A003 has groove B, and there is fixture block A described upper lock core A002 lower end, moves down into when coordinating with fixture block A at the groove B of lock core Connection Card A003, and the groove B of lock core Connection Card A003 is stuck in fixture block A place, is in rotatable state; Described lower lock core A004 upper end has groove, described lock core Connection Card A003 lower end is card form, consist of the cooperation that moves up and down in the groove that under inserting, lock core A004 opens the upper end, the structure of lower lock core A004 is as shown in accompanying drawing 12,13,14, after key inserts, push lock core Connection Card A003 and move downward; The position of lock core section is provided with the pellet C that matches with lock core Connection Card A003 under lock core body A001 and lock core Connection Card A003 insert, and when lock core Connection Card A003 is in rotatable state, pushes pellet C at unlocking condition; Be provided with the spring that pushes lock core Connection Card A003 upward sliding between described lower lock core A004 and lock core Connection Card A003.

As shown in accompanying drawing 6,7,8, described upper lock core A002 axially has a groove D, when lock core Connection Card and groove D join, can only move up and down along groove, when moving to groove B when coordinating with fixture block A, just can be driven by key and rotate.

When key insertion lock core puts in place, the bullet groove of key side coordinates successfully with pellet, simultaneously, the length of key lower end will push lock core Connection Card A003, push pellet C by lock core Connection Card A003 and coordinate, only have both to coordinate successfully, could be rotated by key band movable lock core Connection Card A003, and then band movable lock core hypomere A004 rotation, realize unblanking.

In the present embodiment, described key is card form, and as shown in Figure 17, the one side has bullet groove, and opposite side has at least one card slot; Described lock core arranges at least one card A005, described card A005 has arc groove, card A005 plane of living in and key direction of insertion intersect, match with the position of key card film trap in the position of card A005 arc groove, as shown in accompanying drawing 15,16, when key insertion lock core put rotation in place, the arc groove that the card slot of key is stuck in card A005 rotated.Therefore, when unblanking, coordinate merit with pellet except satisfying, with the lock core Connection Card coordinates successfully, also must satisfy card slot one end and match successfully with card A005, just upper lock core is in rotary state, has the function of retrocession.
