Caterpillar track link structure

The utility model provides a caterpillar track chain track section structure which comprises a chain track section body, two rigid holes are symmetrically formed in the chain track section body in a penetrating mode, threaded grooves are vertically formed in the positions, corresponding to the positions of the two rigid holes, of the bottom of the chain track section body in a penetrating mode, and a groove vertical face is arranged on one side of an inner cavity of a limiting groove. And a groove inclined surface is arranged on the other side of the inner cavity of the limiting groove. According to the caterpillar track link section structure, the caterpillar track plate can be firmly fixed, and the caterpillar track link section structure can be used for carrying out anti-rotation treatment on a screw assembly used for fixing the fixed caterpillar track plate on the caterpillar track link section body through matched operation between the rotation limiting mechanism and the limiting groove; and the phenomen
