Abstract

A marble lock comprises a lock cylinder and a lock sleeve, wherein one group of marbles is installed in a marble hole on the upper portion of the lock cylinder, the marble lock is characterized in a moveable elongated slot which is corresponding to the arbitrary marble of the group is arranged aside on the arbitrary marble, a cavity is arranged in the lock cylinder, one ends of a group of steel pieces are fixed in the cavity of the lock cylinder and are hinged on the position of an angle which is close to the lock sleeve, the other ends are inserted in the moveable elongated slot, the number of the steel pieces is equal to that of the marbles, the shape of the marbles is a stepladder-shape with wide an upper portion and a narrow lower portion, narrow heads of the marbles enter the lock cylinder and are contacted with the steel pieces, the diameter of the lower openings of marble holes are less that the upper ends of the marbles, which are matched with the narrow heads of the marbles, wide heads remain in the marble holes of the lock cylinder, and the lengths are different. The key of the marble lock of the utility model has square teeth which are concave and convex on the key shaft, each concave-convex represents a tooth, the concave-convex portions of the key are corresponding to the marbles, each tooth of the key is inserted on a round shaft, the shaft end has a tine or a hole, and each key is at least provided with two long teeth. The marble lock solves the problems of small variety, less number of teeth and the poor safety of key teeth which are matched with the marble lock,.

Description

Cylinder lock and the key that is used with cylinder lock

(1) technical field

The utility model relates to a kind of cylinder lock.

(2) background technology

The key great majority of the cylinder lock coupling of using at present all are pointed tooths, and this key bit changes little, and the number of teeth is few, poor stability.

(3) summary of the invention

The height that the purpose of this utility model provides a kind of tooth changes greatly, and the number of teeth is many, the cylinder lock that security performance is high.

The purpose of this utility model is realized by following mode:

Cylinder lock, comprise lock core and lock tube, lock core top has one group of pellet shot from a slingshot to be contained in the pellet shot from a slingshot intraocular, it is characterized in that all there is a corresponding with it microscler loose slot on described this any one next door of group pellet shot from a slingshot, a cavity is arranged in the lock core, one group of steel disc one end is fixed in the lock core cavity, angle place hinge near lock tube connects, and the other end is inserted in the microscler loose slot, and steel disc quantity equates with marble amount, it is stepped that pellet shot from a slingshot is shaped as upper coarse and lower fine cylinder, the thin head of pellet shot from a slingshot puts in the lock core and contacts with steel disc, and the lower port diameter of pellet shot from a slingshot eye is less than the upper end of pellet shot from a slingshot, is complementary with thin of pellet shot from a slingshot, thick head is stayed the lock core marble intraocular, and is different in size.

The key side of the being tooth of the utility model cylinder lock, tooth differs for convex-concave on the key axle, each concavo-convex tooth of all representing, concavo-convex position on the key is corresponding with pellet shot from a slingshot, each tooth of key is set on the circular shaft, spindle nose band point or band eye, and every key is wanted two long teeth at least.

The utility model has the advantages that: because the tooth of square teeth key changes greatly, the number of teeth is many, so the safety of lock improves greatly when using, with 10 teeth keys is example, general key tooth depth is 5-6mm, facewidth 4mm, and each height of tooth changes at 0.4-0.5mm, per tooth height change minimum has 10 times, and one group of different key has 1,000,000,000 at least; Special key tooth depth 10mm or make the double cog key, one group of key can have 10,000,000,000,000 at least, has so just stopped the phenomenon that a key is driven a plurality of locks.

Fig. 3 is a steel disc shape schematic diagram.

(5) specific embodiment

Embodiment:

With reference to accompanying drawing 1, the utility model cylinder lock, comprise lock core and lock tube, lock core top is one group of pellet shot from a slingshot, it is characterized in that all there is a corresponding with it microscler loose slot 2 on described these group pellet shot from a slingshot 3 any one next doors, a cavity 7 is arranged in the lock core 10, pin-and-hole 14 is arranged on the steel disc 8, one group of steel disc 8 one end is fixed on angle 9 places of the cavity 7 interior close lock tubes 12 on the lock core 10 with pin, the other end is inserted in the microscler loose slot 2, the effect of loose slot 2 is that each steel disc and corresponding with it pellet shot from a slingshot are fixed on the same line, prevents dislocation, and the minimum point of control steel disc 8 and the strong point of key rotation lock core when unblanking; The quantity of steel disc 8 equates that with pellet shot from a slingshot 3 quantity this end width of steel disc 8 steady pins is identical with key bit, and middle part and key bit contact portion width are less than the key bit width, and steel disc stretches into its width of part of loose slot less than the middle part width; It is stepped that pellet shot from a slingshot 3 is shaped as upper coarse and lower fine cylinder, the thin head of pellet shot from a slingshot 3 puts in the lock core and contacts with steel disc 8, the diameter of the end opening 6 of pellet shot from a slingshot eye is less than the upper end of pellet shot from a slingshot 3 on the lock core, be complementary with the thin head of pellet shot from a slingshot 3, the thick head of pellet shot from a slingshot is stayed the lock core marble intraocular, different in size, cooperate with last pellet shot from a slingshot 4 and spring 5 unblank, locking.

The key side of the being tooth of the utility model cylinder lock, side's tooth 13 differs for convex-concave on the key axle, each concavo-convex tooth of all representing, concavo-convex position on the key is corresponding with pellet shot from a slingshot, each tooth of key is set on the circular shaft, and spindle nose band point or band eye guarantee the accuracy of key at the key intraocular, every key is wanted two long teeth at least, and long tooth is done and unblanked or the power of locking supports.

During use, key is inserted key eye 1 key, key bit clockwise rotates along steel disc 8, drive steel disc 8 simultaneously and upwards rotate around bearing pin, jack-up pellet shot from a slingshot 3 is when the position of key turns to loose slot 2, pellet shot from a slingshot has also arrived lockset position of coupler, continues to twist key rotation lock core 10, and lock is opened; Change counterclockwise with key during locking, the position that key bit forwards the key eye to is rotated further, and lock core is forwarded to locked position of coupler 11.

Design majority of the present utility model is used for built-in lock, unblanks also can rotate lock tube, and method is that lock core is fixed, and when key pushes pellet shot from a slingshot to lockset position of coupler, rotates lock tube with external handle, can connect dead bolt around the security door etc. around the lock tube.
