the design is a corrugated paper with pressure-resistant structure, including outer paper layer and corrugated interlayer, corrugated interlayer includes wave curve refill, first cylinder refill, second cylinder refill and third cylinder refill, wave curve refill is folded by the single face corrugated paper and is formed and the bending of dog-ear department is the arcuation, first cylinder refill, second cylinder refill and third cylinder refill are convoluteed by the single face corrugated paper and are formed, the arcuation turning and the outer paper layer of wave curve refill are pasted and are connected, first cylinder refill, second cylinder refill and third cylinder refill cup joint in the space of wave curve refill and outer paper layer.

Preferably, first cylinder refill is tangent with wave curve refill, outer paper layer, second cylinder refill is tangent with wave curve refill, outer paper layer, first cylinder refill, third cylinder refill is tangent with wave curve refill, first cylinder refill, second cylinder refill and third cylinder refill are pasted with contact point separately and are connected.

Preferably, a layer of glass fiber paper is clamped inside the outer paper layer.

Preferably, a paper scrap layer is arranged between the outer surfaces of the glass fiber paper and the outer paper layer in a clamping mode.

Preferably, the number of the second cylindrical paper cores is two.

Preferably, the number of the outer paper layers is two.

The utility model provides a corrugated paper that structure is withstand voltage, beneficial effect lies in: the corner of wave curve refill sets up to the arcuation, can bear bigger pressure, the cylinder refill has cup jointed in the space of wave curve refill and outer paper layer, and tangent mutually between each cylinder refill, can make the pressure that outer paper layer received when passing to the cylinder refill, with pressure dispersion to each cylinder refill on, dispersion pressure, it is more withstand voltage, and be equipped with glass fiber paper in the outer paper layer, make the power that receives on single position all can disperse and come, and the wastepaper layer of establishing in the outer paper layer, play the effect of shock attenuation and dispersion pressure. The utility model discloses in, tangent and the clamp of paper core has glass fiber paper through using a plurality of cylinders for on each cylinder paper core can be dispersed to outside single-point atress, more can withstand voltage, and simple structure is fit for promoting.
