Abstract

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.
