Furthermore, the back of the plate body is a plane, and a diamond-shaped edge is arranged in the center of the plane.

By adopting the scheme, when the base angle is fixedly connected with the rail, the diamond-shaped edges play a role in anti-skidding stability.

Furthermore, the width of the rectangular convex edge is smaller than the width of the rectangular groove and the width of the limiting edge, and the width of the limiting edge is larger than the width of the rectangular groove.

Through adopting above-mentioned scheme, the resilience effect is better, and noise reduction effect is better.

Furthermore, the bottom corners are respectively located at the bottom corners of the two shorter sides of the plate body.

Through adopting above-mentioned scheme, sleeper rail supporting groove edge and backing plate base angle contact for reduce wearing and tearing, the consumption between backing plate and the sleeper.

Furthermore, the plate body is made of thermoplastic polyester elastomer material.

By adopting the scheme, the elasticity is good, the abrasion is small, and the service life is long.
