Abstract
A link chain comprises a chain link including two shank portions and two arc portions connecting the two shank portions. The two shank portions and the two arc portions define an interior space of the first chain link; and a dividing element extends inwardly from an inside surface of one of the two shank portions and extends inwardly from the inside surface of the other shank portion. The dividing element divides the interior space into two movement spaces, and the dividing element has a centerline, and the centerline is not a straight line perpendicular to the shank.
