Abstract:
A bedstead (100), comprising: a first bed rod (1), a second bed rod (2), and a foldable mechanism (3). The foldable mechanism comprises an operation part (31), an engagement part (32), an engagement position-returning member (33), and an adjustment part (34). A first end of the operation part is rotatably connected to the first bed rod. A second end of the operation part is rotatably connected to the second bed rod. The engagement part is movably provided on the operation part between an engaging position and a separating position. When in the engaging position, the engagement part is engaged with the first bed rod. When in the separating position, the engagement part is separated from the first bed rod. The engagement position-returning member is connected between the engagement part and the operation part to constantly drive the engagement part to move toward the engaging position. The adjustment part comprises an adjusting surface (3411) contacting the engagement part. When the adjustment part slides, the adjusting surface structure drives the movement of the engagement part between the engaging position and the separating position. The foldable mechanism of the bedstead is simple. When in use, the bedstead has high safety, and when not in use, the bedstead can be folded to save space.
