Technical Field

The invention belongs to the technical field of locks, and particularly relates to a blade lock core.

Background

The principle of the blade lock is that the teeth with different widths on the key are utilized to prop against and align the blades with different positions in the lock core, so that the lock core is rotated and opened. If two key tartar of this kind of lock differ little, can cause joint department relatively weak between inner bag and the outer courage, can drive the inner bag through twisting the key by force and rotate and realize unblanking, consequently this kind of blade lock prevent violence unblanking ability not enough.

Disclosure of Invention

The invention aims to solve the technical problem of providing a blade lock with strong violence-proof unlocking capacity.

The invention is realized by the following technical scheme:

a blade lock core comprises a lock inner container, a lock outer container, blades and lock pins, wherein the blades are movably arranged on the lock inner container, the lock inner container is fixedly arranged in the lock outer container, a hole groove for a key to insert and can rotate 360 degrees is formed in the lock inner container, blade grooves for the key to pass through and can rotate 360 degrees are formed in the blades, the lock pins can be movably connected to the lock outer container along the axis of the lock pins, a locking edge is arranged on one side of each blade, an unlocking groove is formed in each locking edge, protruding blocks are formed on two sides of each unlocking groove, clamping grooves for the protruding blocks on two sides of each unlocking groove to be clamped into are formed in each lock pin, and the lock pins are in a locking state when the protruding blocks of one or more blades are clamped into; when the convex blocks of all the blades are separated from the clamping grooves of the lock pin, the lock pin is in an axially movable state, and unlocking is realized.

Preferably, one side of the lock liner is provided with a side groove for the lock pin to be partially embedded, at least part of one side of the lock pin with the clamping groove is positioned in the side groove of the lock liner, and when a correct key is inserted, the unlocking grooves of all the blades on the lock liner are in a superposed state with the side groove on the liner, so that the lock pin can move on the side groove.

Preferably, the clamping grooves are a plurality of long grooves, and the direction of the long grooves is consistent with the moving direction of the blades.

Preferably, the key insertion lock inner container part is a stepped cylinder.

Preferably, the front end of the key is in a conical structure.

Preferably, the inner container is provided with a blade spring which pushes the blade towards the center of the lock inner container.

Preferably, the outer container is provided with a latch spring for urging the latch outward.

Preferably, the lock pin is provided with a bulge which is convexly arranged towards one side, and the bulge extends into the spring groove of the lock outer container to compress the spring.

Preferably, the lock further comprises a cover, the cover is connected to the lock outer container, a hole groove for inserting a key is formed in the cover, and a hole groove for ejecting the lock pin is further formed in the cover.

The invention has the beneficial effects that: according to the invention, the inner container of the lock and the blade groove are both provided with the key which can be inserted and can rotate 360 degrees, and the key can rotate 360 degrees after being inserted no matter whether the key is matched or not, and the lock can be unlocked only by ejecting the lock pin after the matched key is inserted, because the movable force of the lock pin is ejected by the lock pin spring, the lock pin can not be ejected as long as a projection on the blade has a certain point (such as 0.3mm projection) and is clamped in the clamping groove of the lock pin, so that the unlocking difficulty of the lock technology is extremely high, meanwhile, the idle running is realized between the key and the lock core, the key cannot be forcibly unlocked by turning the key violently, and the violence-preventing unlocking capability of the. The invention has no place to borrow force to form idle running after other round keys or tools are inserted; the key is round, the key can be inserted in different directions and angles, the lock cylinder and the key can be unlocked without rotating, and unlocking is more convenient and faster.
