SINK DRAIN HOLE STRUCTURE

摘要

A sink drain hole structure, which can be more securely connected with a drain by a connector without loosening. The sink drain hole structure includes a sink main body formed of a rigid wall and a drain hole integrally formed with the sink main body. The drain hole is defined with a horizontal reference axis and a vertical reference axis. The drain hole has an edge section in the direction of the horizontal reference axis for supporting and connecting with a drain (or a drain pipe), a connection section extending from the edge section in the direction of the vertical reference axis and a terminal section (or folding edge) extending from the connection section in the direction of the horizontal reference axis. The terminal section overlaps at least a part of the edge section to form a double-layered structure defining an elastic space.

1. A sink drain hole structure comprising a sink main body formed of a rigid wall and a drain hole integrally formed with the sink main body, the sink main body having a basin in communication with the drain hole, the drain hole being defined with a horizontal reference axis, a vertical reference axis and a central area, the drain hole having an edge section in the direction of the horizontal reference axis for supporting and connecting with a drain, a connection section extending from the edge section in the direction of the vertical reference axis and a terminal section extending from the connection section in the direction of the horizontal reference axis, the terminal section having a tail end, the terminal section overlapping at least a part of the edge section to form a double-layered structure defining an elastic space.
