Fig. 2 is the front view of the first blade in a kind of Lock capable of preventing from being opened by master key core of the utility model;
Fig. 3 is the front view of the 2nd blade in a kind of Lock capable of preventing from being opened by master key core of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the application's scheme is further described:
As shown in Figure 1 to Figure 3, a kind of Lock capable of preventing from being opened by master key core in the present embodiment, comprises lock housing 1, lock gall 2, the blade 3 being arranged on lock gall 2 and key 4, and lock housing 1 has offered open holes 11 in the axial direction, and lock gall 2 is arranged in the open holes 11 of lock housing 1; Lock gall 2 in axial direction offers the key hole 21 mated with key 4 and at least two blade cavities 22 being evenly distributed on surface, blade 3 is arranged in blade cavity 22, wherein blade comprises the first blade 31 and the 2nd blade 31, first blade 31 and symmetrical being arranged in blade cavity 22 of the 2nd blade 31 that are linked by spring 6.
Also being provided with horizontal pin 5 between lock gall 2 and lock housing 1, lock housing 1 inwall has axially offered the accommodating groove (not shown) of horizontal pin, and transverse pin slot 23 has in axial direction been offered on the surface of lock gall 2; Lock housing 1 is provided with two through holes 12, it is provided with in through hole 12 and the elasticity device 7 that horizontal pin 5 cooperatively interacts, elasticity device 7 comprises spring 72, is positioned at the fixed block 71 of spring 72 upper end and is positioned at the cylinder 73 of spring 72 times ends, fixed block 71 is fixed in through hole 12, spring 72 and cylinder 73 can be arranged in through hole 12 along what through hole axial direction due moved, the edge of the first blade the 31 and the 2 32 has a groove (314,324), groove (314,324) mates mutually with horizontal pin 5; When locking core locking state, a part for horizontal pin 5 is inside accommodating groove, another part is inside the transverse pin slot 23 of lock gall 2, in time rotating key 4, horizontal pin 5 contacts with cylinder 73 and applied thrust, cylinder 83 upwards moves thus unlocks, and in time needing lock upper lock core, cylinder 73 recovers original position under the elastic force effect of spring 72.
