Drain plug linkage device

摘要

A drain plug linkage device (100) comprises a pull rod assembly (10) including a pull rod (1) and a link rod (2) operatively connected with each other; a lever member (3); and an engagement mechanism (6). One of the link rod (2) and the lever member (3) comprises a plurality of through-holes (21) and has the engagement mechanism (6) slidably mounted thereon, and the other one of the link rod (2) and the lever member (3) is configured to be inserted through one of the through-holes (21) and includes a plurality of axially-spaced circumferential ridges (32) and recesses (33) defined between the circumferential ridges (32). The engagement mechanism (6) is configured, when sliding into a position of engaging with the recess (33), to prevent the other one of the link rod (2) and the lever member (3) from being axially displaced with respect to the through-hole (21).
