Abstract
The invention discloses a folding support mechanism, a folding bed stand and a folding seat bracket. The folding support mechanism comprises a pin joint rack which includes two connecting rods in pin joint; the folding support mechanism further comprises a support bar; the two connecting rods are slidably connected with a sliding seat respectively, two ends of the support bar are rotatably connected with the sliding seats of the two connecting rods respectively, and maximum rotation unfolding angles of the support bar relative to the two connecting rods are no more than 90 DEG. According to the invention, since the maximum rotation unfolding angles of the support bar relative to the two connecting rods are no more than 90 DEG, the support bar is rotary relative to the two sliding seats; thus, the phenomenon of deadlocking is avoided, it is guaranteed that the support bar moves to a position where the support bar abuts against the two connecting rods so as to maintain unfolding, and the following beneficial effects are obtained: a) unfolding can be maintained by only using one support bar, so the advantages of saving of materials, low cost and light weight are obtained; b) demands for unfolding and folding can be satisfied at the same time; c) unfolding and folding are convenient and smooth, and the folding support mechanism has a long service life; and d) strength of the connecting rods are not influenced.
