Disclosed is a laminated lock cylinder, characterized in that the laminated lock cylinder comprises a lock cylinder sleeve (10), a plurality of laminations (30) and a plurality of sheet-shaped pins (20), wherein pin grooves (11) are symmetrically formed on an inner wall of the lock cylinder sleeve (10), the plurality of laminations (30) which are laminated in sequence and fixed as a whole are arranged in the lock cylinder sleeve (10) in an axial direction, and each lamination (30) is composed of two arch-shaped half laminations (31); the pins (20) are arranged between the two arch-shaped half laminations (31) respectively and are movable in the pin grooves (11) of the lock cylinder sleeve (10), and key holes (21) allowing a key to be inserted and protrusions (22) forming an unlocking password are arranged on the pins (20); after the plurality of laminations (30) and the pins (20) are superposed, the key holes (21) are aligned to form a lock hole, and when no key exists or the key which is not matched with the protrusions (22) is inserted into the lock holes, one end of the pins (20) are located in the pin grooves (11) to clamp the lock cylinder sleeve (10), such that the laminated lock cylinder cannot rotate; when the key matched with the protrusions (22) is inserted into the lock hole, the pins (20) are driven by the key to move in a radial direction, so that the pins (20) and the laminations (30) form a rotatable cylinder, and unlocking can be achieved by rotation. |
