Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the utility model.
Embodiment 1：
As shown in Figures 1 to 5, the utility model discloses a kind of sealing ring chain, it includes multiple by inner plate 2, set
The chain link that cylinder 4 and special-shaped bearing pin 3 are formed, sleeve 4 is arranged with roller 5 on the cylinder between two relative inner plates 2, adjacent
Connected between chain link by different hole outer plate 1.The left and right ends of different hole outer plate 1 are provided with different hole 11, and special-shaped bearing pin 3 is located in
