Lock.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram for locking pearl；
Fig. 3 is the structural decomposition diagram of the utility model.
Specific implementation mode
Referring to figs. 1 to Fig. 3, a kind of lock core, including lock housing 1, the lock housing 1 has the mounting hole 7 being axially arranged, described
Rotation is provided with lock gall 2 in mounting hole 7, and 2 axial direction of the lock gall is equipped with keyhole 3, towards the key on the lock gall 2
The side in hole 3 is provided with the lock hole of bead 4, is equipped in the lock hole of bead 4 and locks pearl 5, and the lock pearl 5 is by towards the keyhole 3
It cryptography unit 6 and is constituted back to the groove 9 of stirring of the keyhole 3, it is radially movable to be also equipped with one on the lock gall 2
Strip 10, the lock gall 2, which is provided with, holds the opening 8 that the strip 10 passes through, and the madial wall of the lock housing 1 is provided with a bayonet
11, it stirs in groove 9 described in the insertion of the side of the strip 10, the other side is embedded in the bayonet 11, the bottom in the lock hole of bead 4
Clamping is equipped with the first spring 12 between portion and the lock pearl 5, is clamped between the lock gall 2 and the strip 10 and is equipped with second
Spring 13 is additionally provided with trace bar 14 outstanding on the lock gall 2 towards the side of the keyhole 3, this lock core when in use,
Due to the first spring 12 elastic force act on, lock pearl 5 move up block strip 10 side make its be embedded in described in stir groove 9
In, strip 10 is stuck at this time, and the track groove of the accommodating trace bar 14, Yi Jiyu are provided with the matched key of the lock core
The adaptable secret key slot of cryptography unit 6, after key is inserted into the keyhole 3, lock pearl 5 loosens, since the elastic force of second spring 13 is made
With pushing the other side of strip 10 to be embedded in the bayonet 11, key is rotated at this time, lock housing 1 can be driven to rotate together, entirely
Lock core structure is complicated, and pick-proof effect is good.
In the present embodiment in addition to the lock housing 1 and the outer remaining parts of lock gall 2 are symmetrically located at both sides, preferably balance
Torque so that the lock core is more secured, extends physical life.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic
