Abstract
A collapsible structure for baby strollers includes a main frame including two first support rods, each first support rod having an engaging member which includes a protrusion, and a connection part which includes a first hook. Two handles are pivotally connected to the two engaging members respectively, and the two handles are provided with two locking units. Each locking unit includes a first connection member extending through a pull member, a second connection member extending through a restriction member and a third connection member extending through a positioning hole of each handle to be contacted with a resilient member located in a space in each locking unit. The restriction member includes a recess operatively engaged with the protrusion when unfolding the stroller, and a second hook securely engaged with the first hook when the stroller is folded.
