The invention discloses a one-key linkage backrest folding mechanism, and relates to the technical field of folding cart equipment. The mechanism comprises stroller front wheels, stroller rear wheels,a front wheel connecting rod, a rear wheel connecting rod, a first push rod, a second push rod, a first linkage supporting rod, a supporting backrest and a backrest locking piece. During the half-folding of whole equipment, a user only needs to unlock the locking of the whole equipment; then the first push rod is pushed to be bent; therefore, the second push rod, the front wheel connecting rod, the first linkage supporting rod and the second linkage supporting rod are folded towards the position of the rear wheel connecting rod at the same time. Under the pulling of a driving supporting rod,a first transmission steel cable drives the backrest locking piece to be released, at the moment, the supporting backrest is in a loose state and rotates towards the position of the rear wheel connecting rod under the pulling of the first transmission steel cable, and therefore, the whole trolley can be folded in one step.

    本发明公开了一键联动收靠背机构,涉及折叠推车设备技术领域。包括推车前轮、推车后轮、前轮连接杆、后轮连接杆、第一推杆、第二推杆、第一连动支撑杆、支撑靠背和靠背锁止件,设备整体进行对折时,使用者只需要打开设备整体的锁止,然后推动第一推杆进行弯折,从而使第二推杆、前轮连接杆、第一连动支撑杆以及第二连动支撑杆同时朝向后轮连接杆的位置进行折叠,并且在驱动支撑杆的拉动下使第一传动钢索驱动靠背锁止件进行释放,此时支撑靠背处于松弛状态,并且在第一传动钢索的拉动下向后轮连接杆的位置进行旋转,从而实现了一步便能对手推车整体进行折叠。
