Patent ID: 8587647

Claim:
An imager assembly for a remote inspection device, comprising: an imager body having a male threaded portion; an accessory assembly, including: a tubular body portion having first internal female threads engaged with the male threaded portion of the imager body such that rotation of the tubular body portion axially translates the tubular body portion with respect to the imager body; and a mirror obliquely angled with respect to a longitudinal axis of the accessory assembly; and a threaded coupler positioned between the imager body and the tubular body portion having second internal female threads engaged with the male threaded portion such that the threaded coupler is selectively axially translated by rotation to a contact position where the threaded coupler contacts the tubular body portion, the contact position operating to bind the first and second internal female threads with the male threaded portion to prevent axial rotation of the tubular body portion and fix an orientation of the mirror.
