In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: comprise lock body and be provided with the keyhole lock core, described lock core is contained in the slideway of described lock body, described lock core is a hollow cylinder, this lock core middle part is provided with a barrier along axis direction, this barrier is divided into symmetrical halves with described lock core inner chamber, described barrier is provided with even number bar lock pin slideway, this lock pin slideway is symmetrical arranged to described barrier two ends take the mid point of described barrier length direction as basic point, in the described lock pin slideway lock pin is housed, described lock body is provided with many lock pin slots that dock with the external port of many lock pin slideways of this lock core when described lock core turns to latched position in described slideway, described lock pin slot is symmetrical arranged take the described slideway central point of described lock body as basic point; Described lock pin is " ten " font, and the horizontal edge of described lock pin stretches out from described barrier both sides; Its outer gear that is set with of described lock core stage casing, this gear are contained in the gear grooved that described lock body is provided with, and described gear meshes with the gear bar, and stretch out from the gear cylindrical void that described lock body both sides are provided with at these gear bar two ends.
In the technique scheme, scheme is more specifically: have its bottom of a described lock pin to be provided with bending edge, the bending edge of this lock pin is provided with Compress Spring, and the other end of this Compress Spring is crimped on the inwall end face of the described lock pin slideway relative with the bending edge of described lock pin.
Further: described inner ring gear is along gear shaft to being provided with draw-in groove, and described lock core external surface is provided with the fixture block that matches with described draw-in groove.
Further: described lock pin is when its end moves to when concordant with its external port of lock pin slideway, and its other end is just in time concordant with another external port of this lock pin slideway.
Further: described lock body which is provided with the gear hole of described gear.
Further: be crimped with the location snap ring between described lock core external end head edge and the described lock body; Described lock core wherein on one side described inner chamber be keyhole outdoors, this is provided with the envelope piece in another port of keyhole outdoors; The described inner chamber of another side is an interior keyhole, and the another port of this interior keyhole is provided with the envelope piece.
Because adopt technique scheme, the utility model compared with prior art has following beneficial effect:
1, because lock core is a hollow cylinder, this lock core middle part is provided with a barrier along axis direction, this barrier is divided into symmetrical halves with described lock core inner chamber, the two halves cavity that is divided into be respectively outdoors with door in keyhole, and the lock pin slideway is symmetrical arranged, the lock pin slot is symmetrical arranged, lock pin horizontal edge height is symmetrical arranged, and can realize that a lock core one is key door external door drawback lock, the lock component are few, cost is low, and lock core is not allowed perishable, and the antitheft performance is strong.
2, because every lock pin slot of this mechanical lock is an elongated slot that in axial direction arranges, can move forward and backward in slideway after lock core is sealed, increase the difficulty of pirate of the open, the antitheft performance is stronger.
3, this mechanical lock can not need spring, and this allows illegal theft can't obtain to provoke the feel of lock pin, therefore can stop fully to adopt unlocking tool to the technology unlocking of this lock.
4, lock core can be sealed with lock body in the direction that the lock pin slot is arranged, and not needing to forward to a direction initialization could be sealed.
