Abstract
A lock includes a combination code device, a pin, and at least one fixing unit. The combination code device has a plurality of code input units. When the code combination of the code input units is different from a preset combination, the lock is in a locked state, so the pin is engaged with the combination code device and cannot be moved or rotated. When the code combination of the code input units is the same as the preset combination, the lock is in an unlocked state, so the pin can be moved or rotated. When the fixing unit is at a first position, the code combination of the code input units can be changed; when it is at a second position, it fixes at least one code input unit, and at least part of the code combination of the code input units can not be changed.
Claims24
A lock comprising:
- a combination code device having a plurality of code input units, wherein when a code combination of the code input units is different from a preset combination, the lock is in a locked state, and when the code combination of the code input units is the same as the preset combination, the lock is in a unlocked state;
- a pin, wherein the pin is engaged with the combination code device and is non-moveable or non-rotatable when the lock is in the locked state, and the pin is moveable or rotatable when the lock is in the unlocked state;
- and
- at least a fixing unit moving between a first position and a second position;
- wherein, the code combination of the code input units is changeable when the fixing unit is at the first position, the fixing unit fixes at least one of the code input units and at least part of the code combination of the code input units is unchangeable when the fixing unit is at the second position, and the pin and the fixing unit are relatively linked.
A lock comprising:
- a pin;
- a combination code device having a plurality of code input units, wherein when a code combination of the code input units is different from a preset combination, the lock is in a locked state, and when the code combination of the code input units is the same as the preset combination, the lock is in an unlocked state;
- and
- at least a fixing unit fixed to the code input unit and relatively linked with the code input unit;
- wherein, in the locked state, when applying a force to move out the pin, the pin is engaged with the fixing unit, and the code combination of the code input units is unchangeable.
