Abstract

The utility model discloses a safety lock and special-shaped key matched with safety lock. The safety lock is composed of a lock body and a safety cover, wherein a through keyhole is arranged on the safety cover, and a positioning hole and a hollow cavity which is convenient for a key head of the special-shaped key to rotate around an axial cord of the positioning hole in the lock body are arranged on the lock body. The special-shaped key comprises a key handle ring, the key head, a positioning column and a connecting plate, wherein one end of the positioning column is fixedly connected with the key handle ring, the key head is connected on the positioning column through the connecting plate, and the whole special-shaped key is in an 'h' shape. The special-shaped key can be inserted from the keyhole on the safety cover, and when the key head of the special-shaped key is rotated to a position which is positively opposite to the keyhole, the key head can be inserted into the keyhole on a lock pin to open the lock. The safety cover can shield the lock pin, a 'master key' can not be inserted into the lock pin, thereby the lock can not be unlocked, the difficulty of unlocking the lock through adopting other abnormal measures is also increased, and the safety level of the lock is increased.
