The utility model relates to the technical field of roll
meal heat preservation boxes, in particular to a roll
meal heat preservation box layered
locking mechanism which comprises a box body, a box cover body, a supporting bottom plate and two sets of bottom partition plates, the box cover body is rotatably installed at the upper end of the box body, the supporting bottom plate is fixedly installed on the outer wall of the bottom end of the box body. According to the layered
locking mechanism of the group
meal heat preservation box, the inner partition plate and the upper partition plate which are detachable are arranged in the box body, and structures such as the T-shaped inserting pieces and the limiting inserting strips are introduced, so that a flexible layered adjusting
assembly is formed, and rapid disassembly and
assembly and recombination can be conducted according to the heights and sizes of meal boxes of different specifications in group meal; according to the layered design, the limitation of a traditional fixed partition plate is broken through, flexible configuration of the space height is achieved, the internal volume
utilization rate is increased, the single heat preservation box is made to meet the stacking requirement of multiple meal boxes, the partition plate is designed to be detachable, and maintenance and cleaning of the box body are facilitated.
