Bed frame structure

Abstract

The bed frame structure, including leg posts and beams. An upper part of each leg post has connection wing plates. Each connection wing plate is quickly assembled/disassembled with an end portion of a respective beam through at least one quick-connect assembly. Each quick-connect assembly has a quick-connect hole and a quick-connect fastener on a respective connection wing plate and the corresponding end portion of the respective beam. No tools are required assembly. Users can achieve connection of a leg post and a beam manually through a corresponding pair of quick-connect hole and quick-connect fastener, such that assembly of the bed frame is easy and effort-saving.
