This product has a continuous structural surface. When the expansion body expands, the upper diameter decreases and the lower diameter increases. The back bolt expansion body changes from a cylindrical surface to a conical surface, with an equal surface area. The radius of the conical surface of the expansion body is equal to the radius of the conical surface of the stone bottom hole, and the two surfaces form a concentric meshing state without stress. Due to the concentric conical surface meshing between the expansion body of the back bolt and the bottom cutting hole of the stone, the meshing area is correspondingly increased. In similar products, under the same stress conditions, the meshing pressure is reduced, effectively improving the load capacity of the stone and the back bolt.
Irregular back bolts can be customized according to the design
