Adjustable support for foldable bed frame

Abstract

An adjustable support for a foldable bed frame is provided, comprising an inner tubular bar with an inner hole, and an outer tubular bar slidably coupled to the inner tubular bar and having an outer hole corresponding to the inner hole. A locking mechanism inside the inner tubular bar includes a fixing pin inserted into the inner hole and an elastic member connected to the fixing pin, wherein the fixing pin protrudes outwardly to engage the outer hole and restrict sliding of the inner and outer tubular bars. A release mechanism includes a sleeve fixed to one end of the outer tubular bar, a through-hole in the sleeve aligned with the outer hole, and a locking screw threadably engaged with the through-hole to actuate the fixing pin, thereby selectively releasing the locking mechanism. The support enables secure locking when extended and easy unlocking with minimal force when folding the bed frame.
