Foldable buffer packing box

Abstract

Most of freight wood boxes, plastic transfer boxes and metal containers cannot be folded, and are provided with no buffer structure; the first one causes high backhaul cost of empty boxes, and the latter one needs to add additional buffer piece cost for damageable goods; and according to the reactive force law, the average life of packing boxes is shortened through the transportation impact. The invention discloses a foldable buffer packing box; the mutual conversion of two states of formation and folding of the packing box is realized through series of hinges; through combined application ofsuch structures as side plate dowel pins, side plate hinges with deflected rotating shafts, bolts between separation plates and buffer support legs, the technical difficulty of lower connecting strength in movable connection of hinges compared with fixed connection is solved; the foldable packing box can be enough to bear such dynamic loads as vibration impact and stacking in the transportation process; the empty box transportation cost is reduced; meanwhile, the cost of goods buffer packing can be reduced through buffer support legs; and through avoided box internal space, the goods transportation cost can be reduced.

Description

Technical field [0001] The invention relates to the technical field of cargo transportation packaging, and relates to a foldable cushioning cargo transportation packaging box. Background technique [0002] Most of the wooden boxes, plastic turnover boxes, and metal containers used for cargo transportation packaging cannot be folded, and there is no buffer structure. Among them, the inability to fold empty containers consumes more road resources and increases transportation costs. Especially for parts supply chains similar to the automotive industry, the cost of returning empty containers for special container-type turnover boxes is very high; and the buffer structure is missing. It is not only necessary to add additional cushioning materials to many vulnerable goods for protection; according to the law of reaction force, the impact generated by cargo handling and uneven roads is not only applied to the goods through the bottom of the packing box, but also the goods are hamme...
