<p>An upper and lower sleeve connecting mechanism of a water inlet valve is provided, including an upper sleeve (100), a lower sleeve (200) and a fastening ring (300). The lower end part of the upper sleeve (100) is provided with a plurality of vertical grooves (111) leading to the lower end face of the upper sleeve (100). A supporting bar (160) is formed between each two adjacent vertical grooves (111). A bulge (120) and a convex rib (130) are arranged at an interval on the lower end face of at least one supporting bar (160). Upper and lower annular flanges (140, 150) are arranged at an interval on the periphery of the lower end part of said upper sleeve (100). The upper end part of said lower sleeve (200) is sleeved into the lower end part of the upper sleeve (100). Said fastening ring (300) is rotatably sleeved on the periphery of the upper sleeve (100) and is clamped between the upper and lower annular flanges (140, 150). A barb (310) is convexly arranged on the lower end face of the fastening ring (300). The barb (310) is controlled to rotate between a loosening position matching with a vertical groove (111) and a locking position between the bulge (120) and the convex rib (130) by rotating the fastening ring (300) relative to the upper sleeve (100). Said upper and lower sleeve connecting mechanism of the water inlet valve has the following advantages: not only makes the adjust of the positions of the upper sleeve and the lower sleeve easy and convenient, but also ensures the upper sleeve and the lower sleeve won't axially shift when falling down or being vibrated.</p> |
