Patent attributes
A chain plate structure includes a link plate body and a sleeve. The link plate body has an acting surface being provided with a first approach edge, two combining portions, and a limiting block located adjacent to the first approach edge. The limiting block has an altitude higher than an altitude of the acting surface. The sleeve is mounted on the link plate body and has a through hole whose maximum diameter is greater than a maximum diameter of a raised ring peripherally formed on the corresponding one of the combining portions. Therefore, when two of the link plate bodies are combined together, a first space is formed between the acting surfaces of the two aligned link plate bodies. The limiting block serves to limit the first space, while the sleeve is allowed to move on one of the combining portions so as to provide a second space.
