The knob lock of the present invention includes a knob, a first driving unit disposed on the knob, a driving barrel, a second driving unit, a lock unit, and a lock core. When the lock core is in a locked state, the driving barrel is restricted from rotating by the lock core, and the knob rotates alone with respect to the driving barrel. When the lock core is in an unlocked state, the restriction to the rotation of the driving barrel by the lock core is removed, the first driving unit applies a driving force on the second driving unit when the knob rotates, and the driving force rotates the driving barrel to make the lock unit rotate together.

A control unit 1 for the lock of a safe having a front housing part 4 and a rear h housing part 3. A controller 6 is integrated in the control unit 1 that, when a correct combination is entered in the keypad 5, moves a module through a motor 11 in the number of turns corresponding with this combination. The module has a transmission board 8 integrated in the housing 2 of the control unit 1 and a bolt 9 for actuating the safe's lock.

A lock is provided, the lock having: a lock mechanism having a first member and a second member, the first member and the second member each being slidably mounted to a housing of the combination lock, wherein the first member is capable of movement between a first position and a second position and the second member is capable of movement between a first position and a second position and wherein movement of the first member from the first position to the second position causes the second member to move from the first position to the second position; a bolt configured for movement between a locking position and an unlocking position, the bolt preventing the second member from moving from the second position to the first position when the bolt is in the locking position.

An apparatus includes a lock assembly configured to be selectively coupled to a selectively-movable lock member of a mortise-cylinder housing of a mortise cylinder. The lock assembly includes visible symbols configured to be selectively movable. This is done in such a way that the visible symbols, in use, urge the selectively-movable lock member of the mortise-cylinder housing of the mortise cylinder to move from a locked state to an unlocked state.

A combination lock structure for simple password retrieval is provided. An inner sleeve is formed with a V-shaped groove. A clamping plate is provided with a V-shaped angle corresponding to the V-shaped groove. A hasp plate is provided with a hasp. A cylindrical flange of the inner sleeve is formed with a hasp groove for engagement of the hasp. A lower end of the hasp plate is provided with a convex point. A lock cylinder is formed with a protrusion corresponding to the convex point. When the lock cylinder is turned to an unlocked position, the protrusion urges the convex point to move upward and the hasp is moved upward so that the hasp is pressed against the cylindrical flange. When the hasp is engaged in the hasp groove, the V-shaped angle is engaged in the V-shaped groove.
