Electronic lock where using a signal from the key and having an anti tamper mechanism

摘要

An electronic locking system (10) comprises a cylinder (14) housed within and rotatable with respect to a shell (16). At least one of the key (18) and the cylinder (14) is capable of generating a signal. An electrically powered locking mechanism is housed within the cylinder (14) and includes a lock member (12) movable between an open position and a locked position. The lock member (12) in the locked position interferes with the rotation of the cylinder (14) with respect to the shell. The cylinder (14) further includes an interfering member (90), movable between an interfering and non- interfering position, which resists movement of the locking member (12) when it is in the interfering position. In addition, an anti-tamper mechanism selectively resists movement of the lock member in response to longitudinal movement of the cylinder.
