Abstract

This utility model discloses a pressure-resistant and fold-resistant corrugated cardboard structure, including a board body with a groove and a through hole penetrating the board body. A vertical plate is engaged with the groove, and a fixing rod with the through hole is fixed on the vertical plate. The fixing rod is threadedly connected to a collar, and a limiting member is provided on the board body to limit the collar. In this utility model, the through rod is slidably connected to arc-shaped groove one and arc-shaped groove two, and the through hole extends into the corresponding hole on the collar. The locking block at the end of the through rod engages with locking groove one and locking groove two. At this time, the locking block is fixed to the board body and the vertical plate as a whole. The vertical plate can increase the pressure resistance and fold-resistant capacity of the board body, thereby preventing the board body from being damaged under force.
