[0007] Preferably, the carton, vertical paperboard corner guard, horizontal paperboard corner guard and box mouth reinforcing frame are fixedly connected by mutual adhesion or sealing nails.

[0008] Preferably, the bottom of the horizontal paperboard corner guard and the vertical paperboard corner guard is located at the same horizontal plane, and the height of the horizontal plane corresponding to the bottom of the horizontal paperboard corner guard and the vertical paperboard corner guard is not lower than the height of the horizontal plane corresponding to the lower surface of the carton.

[0009] Preferably, the vertical height of the third overlapping connecting part is the same as the vertical height of the box opening reinforcing frame, and the top of the box opening reinforcing frame is located at the same horizontal plane as the top of the carton.

[0010] Preferably, the depth of the slot in the horizontal direction is not more than half the thickness of the box opening reinforcing frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model discloses a vertical paperboard corner guard, a horizontal paperboard corner guard and a box opening reinforcing frame are arranged on the positions corresponding to the twelve edges of the carton surface, and are arranged on the outside of the carton, which does not affect the internal dimensions of the carton, and strengthens the front-back direction, left-right direction and up-down direction of the carton, improves the compression strength of the carton, improves the compression resistance of stacking and clamping, is favorable to the storage and transportation of the loaded goods, is convenient to use, and solves the problem that the common corner reinforcing type carton only reinforces the edges of the positions corresponding to the four vertical edges of the carton, and the horizontal edges of the carton surface are not generally strengthened, which causes the carton to be easily deformed horizontally and the internal goods to be damaged when the carton is clamped and carried by the clamping vehicle.
