Abstract
The utility model discloses a blade lock cylinder and a key. The lock cylinder comprises a lock body, a copper core, blades, springs and sheet lock rings. The copper core is directly installed in the lock body, the front end of the copper core is provided with a key hole, and the back end face of the copper core is provided with a protruding tooth. The peripheral wall of the copper core is provided with one or more through grooves in the axial direction, the springs and the blades are installed in the through grooves, and the side edges of the blades are provided with teeth. The corresponding position of the lock body is provided with one or more through grooves in the radial direction, the sheet lock rings are installed in the through grooves, and when the key is inserted and the functional teeth on the blades are flush with the sheet lock rings, the rotation of the lock cylinder is achieved. According to the blade lock cylinder and the key, the blades (sheet marbles) are arranged in the transverse circumference, a lock shaft cannot be rotated until the key is inserted and the deepest functional tooth on a locking plate is flush with the lock rings so that the unlocking purpose can be achieved, and the effective mutual unlocking rate of a lock can reach to more than one 400 millionth. According to the blade lock cylinder and the key, the mutual unlocking rate can be effectively reduced, the safety performance is enhanced, the technical unlocking is prevented, and the lock can be prevented from being forcefully unlocked and being invaded by foreign matter. An appropriate lengthening sleeve is selected according to the thickness of a door, the adaptability of the lock is improved, and the using range is enlarged.
Description
Technical field
The present invention relates to field of lockset, specifically a kind of blade lock core and key.
Background technology
Current blade lock core is to replace pellet with blade, when key inserts lock core keyhole, utilizes the blade longitudinal arranged in a straight line in tartar alignment lock core on the key, is rotated to realize open by key band movable lock core.Still there is potential safety hazard in this kind of blade lock core: may be substituted key insertion keyhole by unlocking tool and carry out violence unlatching; Because blade arranges separately and can freely stir, thereby easily stirred piecewise to test to crack, realize opening lock master; Mutual opening rate is higher etc.
Summary of the invention
The object of the invention is the property safety in order to ensure people, promote lock industry integral level, a kind of blade lock core and key are provided, solve common lock core and easily by unlocking tool violence unlatching, blade, arranged separately and easily crack opening lock master and higher etc. the problem of mutual opening rate of realizing.
The present invention's adopted technical scheme of dealing with problems is: a kind of blade lock core and key, described lock core includes lock body, the copper heart, blade, spring, sheet lock ring, described copper is felt at ease and is contained in lock body, and copper heart front end has keyhole, and copper heart rear end face is designed with double wedge; At copper heart perisporium, have vertically one or more groove, mounting spring and blade in groove, the side of blade is designed with tooth; In described lock body relevant position, radially have one or more groove, sheet lock ring is installed in groove, after inserting key, when the tooth on blade flushes with sheet lock ring, realize lock core and rotate.
Described copper heart perisporium has 4-8 bar groove vertically, at cross section along circumferential arrangement.
Tooth on described blade is designed to deep mixed multiple tooth shape, includes function tooth and empty tooth.
Described lock core front end is set with spreading cover through attaching nut.
And the phase-locked key of joining of aforementioned integral blade, described key leading portion end face has grooved tartar.
Know-why of the present invention is that lateral circumferential arranges blade (chip pellet), traditional locks is longitudinal circular pellet that arranges arranged in a straight line, traditional locks is after key inserts, upper and lower pellet flushes with inner core, and inner core rotates, and reaches the object of unblanking, and lock of the present invention inserts after key, after on locking plate, the darkest function tooth flushes with lock ring, lock shaft could rotate, and reaches purpose of opening.Blade and the mutual lock-in techniques of lock ring that the present invention adopts, when rotating lock shaft, blade is locked, design four groups during with blade, the mutual opening rate of lockset can be realized effective more than 1/400000000th, on every blade (pellet), establishing a plurality of empty teeth and function tooth (multi-disc pellet) carries out organic permutation and combination and reduces mutual opening rate, increase safety, effectively prevent technical opening; In the present invention, keyhole design seal closure, is blind hole, cannot insert the firm tool that goes into operation by force, has effectively avoided violence to open by force with foreign matter and has entered simultaneously; The present invention is also designed with spreading cover, can match suitable spreading cover according to the thickness of door, has improved compliance and the scope of application of lock.Its tartar of the key that the present invention matches is arranged on key leading portion end face, increases difficulty of processing, is difficult for imitated.
