| description | The utility model belongs to the technical field of anchor bolts, and relates to a self-tangent mechanical anchor bolt. The expansion screw comprises a screw rod, a sleeve is movably sleeved outside the screw rod, two ends of the screw rod extend out of the sleeve, a locking mechanism is connected between the sleeve and the screw rod, the lower end of the sleeve is fixedly connected with an expansion mechanism, the lower end of the screw rod is fixedly connected with a hexagonal part, and the hexagonal part is located below the expansion mechanism. When the self-tangent type mechanical anchor bolt is used, the expansion mechanism is divided into six pieces which are tightly attached to the six edges of the hexagonal part, so that the key locking effect can be formed mutually, the anchoring effect is effectively improved, relative rotation of the hexagonal part and the expansion mechanism on the sleeve can be effectively avoided, and the use convenience of the self-tangent type mechanical anchor bolt is effect |
