[0005] Preferably, the first O-ring is located on the inner side of the mounting block, and the surface of the first O-ring is tightly fitted to the inner side wall of the mounting block.
[0006] Preferably, a gasket is provided between the top end of the mounting block and the bottom end of the shell, and the bottom end of the gasket is tightly fitted with the surface of the second O-ring.
[0007] Preferably, a water inlet hole is provided at the bottom end of the mounting block.
[0008] Preferably, a spray arm is fixedly connected to the side of the shell, and two groups of the spray arms are provided.
[0009] Beneficial Effects
[0010] The utility model provides a water-leakage-proof rotating spray arm structure for a bottle washing machine. Compared with the prior art, it has the following beneficial effects:
[0011] 1. The anti-leakage rotating spray arm structure of the bottle washing machine is provided with a mounting block, a first O-ring, a second O-ring, a gasket, a latch and a cotter pin. When water is taken in by the equipment, water enters the fixed shaft from the water inlet hole at the bottom of the mounting block and then enters the spray arm. The water outlet power holes opened opposite to each other at both ends of the spray arm push the spray arm to rotate, driving the drain holes on the spray arm to perform rinsing. The sealing of the gap is strengthened by the first O-ring and the second O-ring. The integrity of the fixed shaft and the mounting block is strengthened by the latch and the cotter pin, so that serious water leakage at the connection during rotation can be avoided and the rotation can be basically maintained in one plane.
