Along with the popularization range of corrugated box becomes wide, and the article of inside deposit is also more and more complicated, and weight is also more and more big, and present corrugated box bearing resistance to compression has not satisfied the current situation far away, and the broken hourglass phenomenon of the visible corrugated box everywhere needs follow corrugated box plate structure and sets out, promotes self structure bearing capacity.

Disclosure of Invention

Not enough more than, the utility model discloses the device provides a resistance to compression corrugated box.

The utility model discloses the technical scheme that its technical problem was solved to the device adopted is: the pressure-resistant corrugated case mainly comprises an upper case board, a wave flute, a middle clapboard and a lower case board, wherein the whole corrugated case board is of a double-layer structure consisting of the upper case board, the lower case board and the middle clapboard, the wave flute is arranged between the upper case board and the middle clapboard, the wave flute is also arranged between the lower case board and the middle clapboard, fixed mandrels are arranged in sinusoidal hole grooves of the wave flutes of the upper layer and the lower layer in a staggered manner, a heavy object is placed on the upper case board of the corrugated case board, the fixed mandrels are cylindrical, supporting mandrels are uniformly arranged inside the fixed mandrels, main arc grooves are arranged at the positions where the fixed mandrels are in stressed deformation contact with the inner side surfaces of the upper case board and the lower case board, middle arc grooves are arranged at the positions where the fixed mandrels are in stressed deformation contact with the inner side surfaces of the middle, that is, the trough of the wave corrugation contacting with the upper box plate corresponds to the crest of the wave corrugation contacting with the lower box plate.

The working principle is as follows: when the upper box plate is pressed by a heavy object, the upper box plate is pressed downwards to deform, at the moment, the main arc groove on the inner side of the upper box plate is in contact with the wave corrugation on the upper layer and the outer circular surface of the fixed core rod, the stress area is increased, the damage of stress concentration to the box body is reduced, the fixed core rod also sinks after being pressed, when the main arc groove is in contact with the middle arc groove on the middle partition plate, the stress reduction effect of the same principle is generated, the middle partition plate sinks according to the similar principle, similarly, the contact area is increased twice by the contact of the middle arc groove with the wave corrugation on the lower layer and the outer circular surface of the fixed core rod, the stress concentration is reduced, the pressure of the whole box body to the.

In order to further improve the pressure resistance of the corrugated case, the wave troughs of the wave corrugations on the two sides correspond to the wave crests, and the wave crests correspond to the wave troughs, so that the uniform dispersity of gravity is effectively improved, and the concentrated damage to the case body is reduced.

The utility model discloses the technical scheme who provides of device is useful: the fixed plug of cylinder has been installed in the design in wave flute crest trough position to add the support plug in inside and support the most supplementary support, increased the compressive strength of whole tank wall structure, the cooperation is the arc groove that sets up on boxboard contact end face, and the area of contact effectively increases after the compressive deformation, reduces stress concentration, and in addition wave flute sine trough crest corresponds in proper order, improves the dispersibility of power, and the secondary improves the compressive capacity of flute case.
