Title: ADJUSTABLE BABY MATTRESS
Abstract:
Disclosed is an adjustable baby mattress, comprising a bed frame (1), wherein a sunken chamber (11) recessed downwards is provided in the middle of the bed frame (1), and a bed board (2) capable of extending and deforming forwards and backwards is provided on an upper port of the sunken chamber (11); and a front and a rear end of the bed board (2) are respectively connected to the bed frame (1) via telescopic connecting rods (3), and an extending mechanism is provided on a bottom surface of the bed board (2). The mattress has a simple and rational structure, in which the bed board (2) is formed by successively joining a plurality of back plates (21, 22, 23) of equal width, the arc-shaped bottom surface of the bed board (2) cooperates with a transmission twisted rope (47), and a worm motor (41) drives a driving pulley (44) to tightly twist the transmission twisted rope (47), so that the bed board (2) is lifted up to extend and become flat; and the bed board (2) with an arc-surface structure is more suitable for the sleeping posture of an infant, and the bed board (2) can swing left and right on the bed frame (1) via the swing mechanism, thereby reducing the nursing time of the guardian and improving the user experience.
