Anti-fracture nut assembly

The anti-fracture nut assembly comprises a nut body and a screw rod, the screw rod is installed in the nut body, threads are arranged on the outer wall of the screw rod in a reinforcing mode, the screw rod is connected with the internal threads of the nut body through the threads, a blocking device is installed below the nut body, and the blocking device is connected with the nut body. And a connecting device is mounted above the blocking device. According to the anti-fracture nut assembly, the base plate and the nut body can be sequentially installed on the screw rod, the flange can support the nut body through the base plate, meanwhile, the flange is connected with the nut body in a welded mode so that the anti-fracture purpose can be achieved, and then a trapezoidal plate drives a baffle to move through an L-shaped plate and the like; in this way, the baffle can abut against the screw, and therefore the nut body, the screw and the like can be prevented from loosening. 本实用新型公开了一种防断裂螺母组件，包括螺母本体和螺杆，所述螺母本体的内部安
