Title:
INNER DIAMETER-ADJUSTABLE RING
Document Type and Number:
WIPO Patent Application WO/2017/171192
Kind Code:
A1
Abstract:
Disclosed is an inner diameter-adjustable ring. According to an embodiment, the inner diameter-adjustable ring includes a body part and an inner diameter forming part. The body part has a first moving passage therein. The inner diameter forming part has a second moving passage therein and moves along the first moving passage, and during movement, an outer surface of the inner diameter forming part is coupled to an inner surface of the body part that forms the first moving passage, so that the inner diameter of the ring is formed. The first moving passage connects one side and the other side of the body part, which face each other. The second moving passage connects one side and the other side of the inner diameter forming part, which face each other. The other side of the inner diameter forming part is introduced into the first moving passage from the one side of the body part, so that the inner diameter forming part moves along the first moving passage. The second moving passage forms the inner diameter of the ring. In this case, since a cross-sectional area of the first moving passage, which is formed in a direction from the one side of the body part to the other side of the body part, is not the same, a cross-sectional area of the second moving path changes while the inner diameter forming part moves along the first moving passage, and thus the inner diameter of the ring is adjusted.
