The invention relates to a protective plate hook with a graphite nano self-lubricating material, which is characterized by comprising a plate hook main body, the plate hook main body is formed by sequentially connecting a connecting end, a transition section and a hook-shaped end part into a whole from top to bottom, and the connecting end, the transition section and the hook-shaped end part are all in a plate shape; the connecting end is round, a connecting hole is formed in the center of the connecting end, and the connecting device is characterized in that a shaft sleeve is detachably installed in the connecting hole of the connecting end, an arc-shaped groove is formed in a groove of the hook-shaped end part, the arc-shaped groove is detachably connected with a hook core bearing protection plate, and the hook core bearing protection plate is connected with the shaft sleeve. The shaft sleeve and the hook core bearing protection plate are respectively provided with a self-lubricating structure. By means of the self-lubricating structure, the plate hook center bearing protection plate and the surface of the shaft hole shaft sleeve not only have good protection performance, but also have a good self-lubricating function, and friction heating can be effectively reduced.
