Locking core with irregular thick locking piece

The invention relates to a lock core with irregular thick locking pieces, in particular to a locking piece arranged by at least two different thickness specifications, which is arranged in the core body, which can greatly increase the number of arrangement of safety passwords. Reduce the repetition probability of the same unlocking password, and increase the difficulty of the thief to detect the safe unlocking position of each locking piece, in order to improve the effectiveness of the anti-theft security.

The lock body currently used has a lock core structure, which generally has a body, a core is mounted on the body, and a lock bolt is arranged between the core body and the body, and a lock is interlocked by a correct key. The plug is such that the core and the body are unfastened, and can be freely rotated in the body to be in an unlocked state.

In the early locks, the lock bolts are in the form of a plurality of pairs of lock beads, which are respectively radially disposed between the body and the core body, and the pairs of lock beads are moved to the intersection of the body and the core body by the correct key. Surface, and unfasten the body and the core body, if the core can be rotated by interlocking the correct key, and the lock is in a locked state; however, the lock core in the form of a lock bead, the thief can apply a rotation to the core In the case of the force, the lock can be easily unlocked by the tools one by one, and therefore, the lock of the type has a very weak anti-theft effect.

For this reason, the creator of this case has previously revealed a lock core structure and applied to the bureau for approval of a new type of patent [Announcement No. 088732], which is structured as shown in the first figure. The main body (101), the core body (102), the lock bolt (103) and the plurality of locking pieces (104), wherein the core body (102) is installed in the body (101), and is usually the lock bolt ( 103) snapping with the body (101) [as shown in the second figure], unable to rotate freely, when inserting a correct key (K) into each of the locking pieces (104), the lock can be made by rotating The unlocking pockets (104a) of the piece (104) are respectively aligned with the locking bolt (103), as shown in the third figure, and the locking bolt (103) is slid into the unlocking pocket of each of the locking pieces (104). (104a), that is, hidden in the core (102), the core (102) is unfastened from the body (101), and when the core (102) is rotated, as shown in the fourth figure, The paddles (104b) protruding from at least one of the locking pieces (104) are linked to rotate the core (102) to perform an unlocking operation. In the above structure, since the unlocking pocket (104a) can be distributed within 360 degrees of the circumference of the locking piece (104), and a part of the locking piece (104) can rotate in the body (10), the thief detection is greatly increased. The difficulty of unlocking the positive position, the anti-theft security effect, the older lock bead lock core, is more excellent.

However, when the thief tries to open the above-mentioned lock, the lock piece (104) is usually dialed or manipulated by tools, and the thief's own experience or the assistance of the electronic device can detect the pair of lock pieces (104). The correct position of the unlocking, under the condition of patience and time, the above-mentioned lock can still be opened, the main reason is that each of the locking pieces (104) arranged in the core (102) is the same. The thickness of the thief can easily obtain the conventional locks on the market, and the thickness of each lock piece (104) is known from the conventional locks purchased, so that the tool can be used every time for theft. A distance equal to the thickness of the locking piece is fed, and exactly the position of each piece of locking piece (104) is correctly aligned, and each piece of locking piece (104) is properly fiddled to unlock the locking piece.
