ABSTRACT:
A bottom bracket of a playpen includes a support seat, and a rotation seat. The support seat includes two covers, a slide, a locking rod, a drive rod, an elastic member, a pull handle, and a pull strap. The rotation seat includes two pivot members and a limit plate. Thus, the user only needs to pull the pull strap upward so to fold the bottom bracket, so that the bottom bracket is folded easily and rapidly, thereby facilitating the user folding the bottom bracket. In addition, each of the two pivot members is locked by the locking rod exactly when the bottom bracket is expanded, thereby preventing the pivot members from being pivoted unintentionally, so that the bottom bracket is positioned rigidly and stably without detachment.
