Abstract
This invention of a shield of keyhole includes: a lock core seat, a fixing seat, a shielding piece, a revolving block, a shell, and a magnetic key. The magnets inside the shell are braked in the groove around the revolving block to limit rotation of the revolving block, such that the shielding piece shades the hole of the lock core seat to obtain anti-thieving effect. The magnet on the inserting end of the magnetic key and the magnet of the shell are of the same magnetic pole and therefore offer easy unlocking mechanism. There are protection ring around the hole of the shielding piece to retard rust; and installation space is minimized for the holes of the lock core seat, fixing seat, shell, revolving block and shielding piece circle the same center.
