Abstract

The utility model discloses a cushioning structure of a single wall corrugated fiberboard lined in a packing case, which comprises a single wall corrugated fiberboard body in a rectangular shape; creases are arranged on the single wall corrugated fiberboard to divide the single wall corrugated fiberboard into a base fiberboard and side fiberboards on both sides, then the creases of the side fiberboards on the both sides are displayed towards the base fiberboard so as to form two parallel hollow rectangular columns with cross sections at different height, the parallel hollow rectangular columns are fixed on the base fiberboard by using the matching between the clipping tongues of the side fiberboards and the first clipping hole of the base fiberboard, between a second clipping hole of a side wing fiberboard and the clipping walls of the side fiberboards as well as between the first bayonet of the side wing fiberboard and the second bayonets of the side fiberboards, and the supporting of the side wing fiberboard to the inner walls of the two hollow rectangular columns is also utilized. The cushioning structure of the single wall corrugated fiberboard is both environment-friendly and cost-saving and has the advantages of simple and easy operation and convenient and reliable forming.

Description

Be lining in the buffering structure of single corrugated board of packing chest in a kind of

Technical field

The utility model relates to the buffer structure that is lining in packing chest in a kind of, particularly relates to the buffer structure that is converted into by single wall corrugated board that is lining in packing chest in a kind of.

Background technology

Along with the fast development of Chinese national economy and the significantly raising of living standards of the people; possessing the various electric equipment products that difference in functionality is arranged also constantly enters in people's the life; because electric equipment products; precision instruments etc. are for impact; vibrations etc. are very responsive; therefore; in the circulation process of electric equipment products; usually electric equipment products to be contained in the packing chest; so that transportation; storage; impact in order to guarantee that electric equipment products are exempted to recruit in circulation process; mechanical loads such as vibration are damaged; particularly in loading and unloading operation; avoid electric equipment products because throwing; stacking collapses; lifting comes off; actions such as the unexpected startup of loading machine and too urgent lifting and cause impact to product; vibration; usually in circulation process, exempt to recruit impact with the protection electric equipment products at packing chest inner liner buffer structure; mechanical loads such as vibration are damaged.Traditional buffer structure generally is to adopt expanded material to be made; make such as adopting polystyrene foam (EPS-Expanded Polystyrene) or polyethylene foams (EPE-ExpandedPolyethylene) or polyethylene foamed copolymer padded coamings such as (EPC-Expanded Polyethylene Copolymer); these materials will progressively be replaced by the environmental protection padded coaming because not environmental protection and recovery are difficult.Paper wood is exactly a kind of environment-friendly type padded coaming that is applied to the packing chest liner recently, the available technology adopting paper wood is made buffer structure and is normally adopted upright the forming of cardboard group more than two or two, like this, not only make the cost height of cardboard, and group complexity consuming time especially when founding into buffer structure, therefore a kind of technology of making buffer structure with single cardboard is just arisen at the historic moment, adopt single cardboard can save packing turnover transport space and expense, the Chinese patent publication number be CN1836985A's " corrugation level buffer structure " be exactly a kind of single cardboard buffer structure, this buffer structure comprises in the rectangle cardboard and by the outward extending side cardboard in four limits of cardboard in the rectangle, the side cardboard of four sides is respectively to curls inward cardboard and fix by ear type tabs in rectangle, its complex structure, and take sheet material, combination operation gets up to waste time and energy, be not suitable for use in the packing of smallclothes product and parts, cause unnecessary cost waste easily.

The utility model content
