Carrycot

Abstract

A carrycot is provided, including: a surrounding frame; a chassis; a folding mechanism connected between the surrounding frame and the chassis; a locking member movably provided on the folding mechanism and having a detent position in which it locks the folding mechanism in an unfolded state and a release position in which it unlocks the folding mechanism in the unfolded state; and an unlocking mechanism including first and second operating members movably provided on the folding mechanism. The first operating member is configured to drive the locking member to move. When the second operating member is in a first position, it is in a movement path of the first operating member; and when the second operating member is in a second position, it is displaced from the movement path of the first operating member.
