Description

Mechanical lock

Technical field

The utility model relates to lockset manufacturing technology field, and especially a kind of have lock body and a lock core, with key operated mechanical lock.

Background technology

Lock is a kind of antitheft and secret instrument that is widely used in, and the century-old time has all been experienced in a kind of replacement that is locked into the more advanced lock of another kind in history.From the marble mechanical lock of the cylindrical lock pin of American L Yale utility model in 1848 so far, technique was continued to use 165 years, but the broken lock of explosion-proof power and professional technique broken lock indifferent; In order to improve anti-theft feature and secret dynamics, in the lock industry, people make great efforts to have created electronic lock, smart lock, coded lock etc., and these locks involve great expense, and have gone bad difficult reparation, and the ordinary people can not accept.So, people are still optimized the lock of L Yale utility model, but also just novel, spend the time on the complicated aspect, to such an extent as to the lock core of major part and the key technology of lock body can not get upgrading, develop into the overlength lock core from short lock core, be increased to two with upper lock core from a lock core, namely in the circle hole shape lock core hole of lock core body, the internal cylinder that is provided with keyhole in it is installed, in internal cylinder, be provided with the marble hole that connects keyhole and internal cylinder lateral surface, in lock core body, be provided with and the marble hole of internal cylinder marble hole one to one, two cylinder-shaped marbles all are installed in the marble hole of internal cylinder and each docking of lock core body, and a spring that acts on the pellet is installed in the marble hole of outer lock core, when the institute bitting is inserted in the keyhole of internal cylinder, the different tooth of height is set on the key just in time the outer end of the pellet in the keyhole is driven on the hole face that internal cylinder and lock core body engage, internal cylinder can be rotated with respect to lock core body drive lockset and unblank; In the time of in internal cylinder or illegal key insertion internal cylinder keyhole are withdrawed from institute's bitting, because the effect of the spring in the marble hole, the mating face that makes two pellets in each marble hole just in time all align in the mating face of lock core body and internal cylinder, and cause at least one pellet to be stuck in this mating face and realize the sealed of lock core body and internal cylinder, the probability difficulty that cracks of lock although it is so increases, but such lock component are various, makes complicated, cause cost high, it is difficult to keep in repair.

The utility model content

Problem to be solved in the utility model provides the mechanical lock that a kind of antitheft performance is strong, component are few.

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.
