In particular, the outer link plate, the inner link plate and the reinforcing link plate are all oblong.

In particular, the convex edge of the outer wall of the reinforcing ring is in circular arc transition.

Particularly, the cross section of the reinforcing rib is trapezoid, and the convex edge of the outer wall is in arc transition.

The beneficial effects of the utility model are as follows: according to the utility model, the strength of the chain is improved by arranging the reinforcing chain plate, the reinforcing ring, the wear-resistant layer and the reinforcing rib, so that the chain is not easy to wear and deform during use, the service life is greatly prolonged, and the working efficiency of the transmission equipment is not easy to influence.
