Abstract

The invention relates to an electronic lock cylinder comprising a lock body (1 and 2), one or two lock cylinder rotor blocks (3) and a plunger latch body (4). A circuit board (5) in the lock body is not provided with a power source, and a key is used for supplying power to the circuit board. Lock cylinder rotors of the lock cylinder rotor blocks and connecting push rods (16) are of a structure that the lock cylinder rotors are engaged with the connecting push rods and can slide relative to the connecting push rods. The plunger latch body is provided with a fan-toothed shaft (20) driven by a motor (19), the two ends of the fan-toothed shaft are provided with blocking plates (21). During unlocking, if a user uses an unauthenticated key, a circuit in a lock is not actuated, the plunger latch blocking plates (21) block the connecting push rods (16) at the moment, and rotation of the key can only make the lock cylinder rotors and the connecting push rods idle and cannot drive a plunger latch to open the lock; and when the user uses an authenticated key, the circuit in the lock actuates the motor, the blocking plates (21) are partially opened by an angle, the connecting push rods (16) are engaged with connecting plates (22) under the action of return springs (17), and the plunger latch can be rotated by the key to open the lock. When the key is pulled out, the lock cylinder rotor blocks are pushed out by return springs (15), the blocking plates (21) return to the axis position under the action of the return springs, and the lock return to the locked state.
