Abstract: A water drain assembly includes an embedding ring and a seal washer, such that when a force is applied to press onto a water drain body, the deformation of hooks disposed at a lower edge of the embedding ring latches the edge of a drain through hole to abut the water drain body and fix the water drain body in position, and a rubber seal ring and a pressing member are installed into an internal hole of the water drain body, and a jam-on member is pressed into the internal hole of the water drain body, so as to press the pressing member down to a predetermined position to deform the seal ring, and achieve a tight pressing relation with a drainage pipe inserted therein to achieve a seal waterproof relation between the drainage pipe and the water drain body, and complete the overall installation of the water drain.

Abstract: A water discharge pipe and drain head assembly structure that, by means of a matched drain head inner diameter bore, seal ring shape, and clamp ring, enables the utilization of a simple stomp operated, additionally fabricated, foot-driven component which is sleeved into the inner diameter bore of the drain head to shove down the clamp ring a predetermined distance and thereby compress and deform the seal ring such that a tightly sealed contact is established against a water discharge pipe inserted through them. The arrangement effectively affords optimal watertight anti-seepage efficacy between the water discharge pipe and the drain head, fully solving the numerous problems and shortcomings of the conventional threaded-type mounting ring.
