ABSTRACT:
A protective device for an electronic lock includes a fixing plate mounted in a casing of an electronic lock and located behind an opening of the casing. The fixing plate includes a through-hole aligned with the opening. A protective cover is mounted to the fixing plate and movable between a shielding position shielding the through-hole of the fixing plate and the opening of the casing and a revealing position not shielding the through-hole of the fixing plate and the opening of the casing. The protective cover is drivable by a motor to move between the shielding position and the revealing position. A keypad is mounted to an outer side of the casing. A motor is activated to drive the protective cover when a pin code is input through the keypad.
