Water pump shaft with connecting mechanism

Abstract

The utility model relates to the technical field of water pump shafts, and particularly discloses a water pump shaft with a connecting mechanism, which comprises a water pump, the connecting assembly is arranged on the surface of the water pump shaft, an embedded connection mode is adopted in the connecting assembly, the situation that when the water pump shaft rotates, torque force is too large, and consequently bolts and nuts are loosened or broken can be prevented, the connecting assembly comprises a first flange plate, and a first threaded hole is formed in the surface of the first flange plate; a rubber pad is slidably connected to the surface of the first flange plate, a second threaded hole is formed in the surface of the rubber pad, a plurality of first trapezoidal blocks are fixedly connected to the surface of the water pump shaft, a first trapezoidal groove is formed between every two adjacent trapezoidal blocks, a cross-shaped groove is formed in the surface of the water pump shaft, and the four ends of the cross-shaped groove are in an arc shape. The embedded connecting assembly can effectively resist torque force and prevent the axis of the water pump shaft from deflecting, so that normal operation of the water pump is ensured.
