A buckle lock comprising: a casing including a central channel, a forward opening in communication with the channel, an intermediate tunnel in communication with the channel, and a rear chamber in communication with the channel through the tunnel, the chamber including a slot aligned with the tunnel and being in communication with the channel; a lever fitted on the channel and including two front bottom legs and a rear button on its top; a tumbler wheel assembly including a plurality of rotatable dials and a spring biased shaft passed through the dials, the shaft including a rear slope acting as a trigger; a sliding block disposed in the chamber and including a front wedge fitted in the tunnel and a transverse passage; a key turning assembly disposed in the chamber and including a keyhole and an inward protrusion having a cam section disposed in the passage; a cover fitted on the chamber; and a tongue including a rear tongue plate having a shoulder wherein in a closed position of the buckle lock, the tongue plate is inserted into the opening with the legs lockingly engaged with the shoulder; whereby turning the dials until a correct combination is shown will enable the shaft to move axially to disengage with the wedge for unlocking the lever such that pressing the button will disengage the legs with the shoulder and pulling the tongue out of the casing will unlock the buckle lock; and inserting a key into the keyhole to turn the key turning assembly about 180 degrees will move the sliding block rearward to partially dispose in the slot for disengaging the trigger with the wedge for unlocking the lever such that pressing the button will disengage the legs with the shoulder and pulling the tongue out of the casing will unlock the buckle lock.
