Abstract
A child play enclosure frame, comprising: a plurality of vertical rods respectively provided with upper frame corner joints and lower frame corner joints, an upper frame. When the child play enclosure frame is in the unfolded position, the lower frame structure is stable. When the upper center set performs an upward relative motion relative to the lower center set, the triangular mechanism and the four-linkage mechanism deform simultaneously, which may force the plurality of vertical rods to remain upright or remain in a state of being approximately upright and synchronously drawing together towards the center, which forces the entire play enclosure frame to fold and collapse.
