Claims

[Scope of utility model registration request]

It consists of a rod having a plurality of protrusions and a plurality of rotating rings into which the rod is inserted, and by placing each rotating ring in a predetermined position, the recesses in each rotating ring match the protrusions of the rod. In a combination lock in which the rod can move forward and backward, the rotary ring is divided into an inner ring and an outer ring, and the inner ring is provided with a recess corresponding to the protrusion of the rod, and the outer periphery is provided with an even number of spherical shapes. The inner circumference of the outer ring has a continuous groove and a spherical chain-shaped circumferential groove in which a spherical concave portion into which the spherical convexity is fitted is continuous. When the protrusion of the rod is aligned with the recess of the inner ring, only the outer ring rotates and the unlocking number and code of each rotating ring can be changed, and the rod is slid in the unlocked state. The combination lock is characterized in that the recess of the inner ring and the protrusion of the rod are disengaged from each other, allowing the combination ring to rotate idly and lock the lock.
