Projector suspension device

Abstract

A projector suspension device includes a casing and a suspension mechanism. The casing defines a space for accommodating an optical projection engine, and the casing has a trough extending into an inside of the casing. The suspension mechanism includes a fixed rod and a movable rod, and the fixed rod is disposed inside and fixed to the casing. One end of the movable rod is connected to the fixed rod, and another end of the movable rod is fixed to a stationary object. The movable rod is slidably coupled to the fixed rod and slides relative to the fixed rod so as to be stored inside the trough or to stick out from the trough.
