Abstract
A protective cover for a keyhole of a lock includes a cap and a pair of shutters. The cap has a crown and a skirt. The crown defines a central through-hole and a pair of radial slots at opposite sides of the central through-hole. The skirt is intended to be connected to the lock rotatably around the keyhole. The shutters each have a first end and a second end, with the first ends pivoted on the lock diametrically about the keyhole, and the second ends formed with respective stubs movable in the slots of the cap. Additionally, the shutters are configured to close the central through-hole of the crown when the cap is turned in a direction relative to the lock and to open the central through-hole of the crown when the cap is turned in an opposite direction relative to the lock.
