Description

Mechanical lock

Technical field

The present invention relates to lockset manufacturing technology field, especially one has lock body and lock core, with key operated mechanical lock.

Background technology

Lock is a kind ofly widely used in antitheft and secret instrument, and a kind of replacement being locked into another kind of more advanced lock, all experienced by the century-old time in history.From the marble mechanical lock of the cylindrical lock pin of American L Yale in 1848 invention so far, technique has been 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 lock industry, people make great efforts to create electronic lock, smart lock, coded lock etc., and these locks involve great expense, and have gone bad and not easily repair, and ordinary people can not accept.So, people are still optimized the lock of L Yale invention, but also just novel, complicated aspect takes time, to such an extent as to the key technology of the lock core of major part and lock body can not get upgrading, overlength lock core is developed into from short lock core, two or more lock core is increased to from a lock core, namely in the circle hole shape lock core hole of lock core body, the internal cylinder being provided with keyhole is installed in it, the marble hole of through keyhole and internal cylinder lateral surface is provided with in internal cylinder, be provided with in lock core body and the marble hole of internal cylinder marble hole one to one, in internal cylinder and each marble hole docked of lock core body, two cylinder-shaped marbles are all installed, and a spring acted on pellet is installed in the marble hole of outer lock core, time in the keyhole of institute's bitting insertion internal cylinder, arranging the different tooth of height on the key is just in time driven on the face, hole that internal cylinder and lock core body engage by the outer end of the pellet in keyhole, internal cylinder can be rotated relative to lock core body drives lockset to unblank, when internal cylinder is exited in institute's bitting or illegal key inserts in internal cylinder keyhole, due to the effect of the spring in marble hole, make two pellets in each marble hole mating face can not 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 to 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, manufactures complicated, cause cost high, it is difficult to keep in repair.

Summary of the invention

Problem to be solved by this invention is to provide 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 solution adopted in the present invention is: comprise lock body and be provided with keyhole lock core, described lock core is contained in the slideway of described lock body, described lock core is a hollow cylinder, a barrier is provided with in the axial direction in the middle part of this lock core, described lock core inner chamber is divided into symmetrical halves by this barrier, described barrier is provided with even number bar lock pin slideway, this lock pin slideway with the mid point of described barrier length direction for basic point is symmetrical arranged to described barrier two ends, described lock pin slideway is built with lock pin, described lock body is provided with many latch channels docked 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 latch channels with the described slideway central point of described lock body for basic point is symmetrical arranged, described lock pin is in " ten " font, and the horizontal edge of described lock pin stretches out from described barrier both sides, described lock core stage casing its outer be set with a gear, this gear is contained in the gear grooved that described lock body is provided with, and described gear engages with gear bar, and the gear cylindrical void that these gear bar two ends are provided with from described lock body both sides stretches out.

In technique scheme, scheme is more specifically: have a described lock pin to be provided with bending edge bottom it, 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 matched with described draw-in groove.

Further: described lock pin is when its one end moves to concordant with an external port of its 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: between described lock core external end head edge and described lock body, to be crimped with location snap ring; Described lock core wherein on one side described inner chamber be keyhole outdoors, the another port of this keyhole is outdoors provided with envelope block; Inner chamber described in another side is keyhole in door, and the another port of this interior keyhole is provided with envelope block.

Owing to adopting technique scheme, the present invention compared with prior art, has following beneficial effect:

1, because lock core is a hollow cylinder, a barrier is provided with in the axial direction in the middle part of this lock core, described lock core inner chamber is divided into symmetrical halves by this barrier, the two halves cavity be divided into be respectively outdoors with the keyhole in door, and lock pin slideway is symmetrical arranged, latch channels is symmetrical arranged, lock pin horizontal edge high degree of symmetry arrange, a lock core one can be realized key door external door drawback lock, lock component are few, cost is low, and lock core is not allowed perishable, and antitheft performance is strong.

2, because every bar latch channels of this mechanical lock is an elongated slot in axial direction arranged, can move forward and backward in slideway after lock core is sealed, add the difficulty of pirate of the open, antitheft performance is stronger.

3, this mechanical lock can not need spring, and this allows illegal theft cannot obtain the feel of provoking lock pin, therefore can stop completely to adopt unlocking tool to the technology unlocking of this lock.

4, lock core is having the direction of latch channels can be sealed with lock body, and not needing to forward a direction initialization to could be sealed.
