Corrugated board with double-layer damping structure

Abstract

The utility model relates to the technical field of packing material, concretely to a corrugated board with double -layer shock -absorbing structure, including two shock -absorbing components of symmetrical arrangement two shock -absorbing components between being equipped with a sponge pad, two ends of the sponge pad are flush with the two ends of shock -absorbing component respectively, and shock -absorbing component includes main plate body, the one side of main plate body close to sponge pad is equipped with parallel first connecting plate and second connecting plate, and the sponge pad is fixed between two first connecting plates. The utility model through symmetrical arrangement two shock -absorbing components and adding sponge pad in the middle, formed the double -layer shock -absorbing system of " wave board combination + sponge pad". The wave crest wave trough of first wave board and second wave board is fixed in alignment, and cooperates the corrugated board between two, constructs multilayer wave -shaped buffer structure, can pass through wave -shaped change dispersion external impact force.
