When the package liner shown in the embodiment is assembled into the state shown in fig. 22, the sixth crease 71 and the seventh crease 81 are processed by the virtual engraving process, so that the rigidity of the positions where the sixth crease 71 and the seventh crease 81 are located is reduced, the deformation resistance is weakened, and when the fourth side 5 and the fifth side 6 are folded, the first limiting portion 7 is driven to bend along the sixth crease 71, and the second limiting portion 8 is driven to bend along the seventh crease 81, so that the state shown in fig. 22 is finally formed.

As shown in fig. 22, the direction parallel to the lower edge of the fifth side surface 6 is the second direction, the direction parallel to the lower edge of the third side surface 3 is the first direction, and the direction perpendicular to the horizontal plane is the third direction. When the article positioning device is used, the article is inserted into the accommodating cavity opening, and the accommodating opening is attached to the surface of the article, so that the positioning effect on the article is generated in the third direction and the first direction. Meanwhile, the end part of the article is propped against the first limiting part 7 and the second limiting part 8, so that the effect of propping and positioning the article in the second direction is achieved, and the article is prevented from shaking in the transportation process. When the outer package of the article is impacted, the wall thickness of the outer package is thickened due to the fact that the first limiting portion 7 and the second limiting portion 8 are equivalent to the wall thickness of the outer package, and then the absorbing capacity of force is improved, so that impact force in the second direction is absorbed through the first limiting portion 7 and the second limiting portion 8, and damage to the article caused by external force is avoided.

Wherein in the third direction, the sixth plate 106, the seventh plate 107, the eighth plate 108 and the ninth plate 109 protrude outwardly with respect to the first plate 101, the fifth plate 105. The present embodiment makes the paper card easier when folded by providing the crease 31 and the third punching slit 32 on the corrugated board.

More specifically, as shown in fig. 24 to 26, the packing box liner formed by folding forms a T-shaped end face 110 in the third direction and the first direction, and the T-shaped end face 110 is perpendicular to the second direction. In use, the product 99 is inserted into the receiving opening, which engages the product surface to create a positioning effect on the article in the second direction and the first direction. The ends of the product 99 are respectively abutted against the sixth plate 106, the seventh plate 107, the eighth plate 108 and the ninth plate 109, an abutting and positioning effect is generated on the article in the third direction, the article is prevented from shaking in the transportation process, and when the outer package of the article is impacted, the positions of the punching openings 32 of the first plate 101 and the fifth plate 105 are equivalent to the wall thickness of the package lining, so that the force absorbing capacity is improved. Meanwhile, due to the fixing action of the sixth plate 106 and the ninth plate 109, the impact force in the first direction and the second direction can be avoided; in the third direction, since there is a cushioning supporting effect of the second plate 102 and the fourth plate 104, and there is a positioning effect of the seventh plate 107 and the eighth plate 108 at the same time, an impact force in the third direction can be avoided.

When the developing cartridge is loaded into the packing box disclosed in the present embodiment, the developing cartridge is first put into the lower casing 1, and the handle of the developing cartridge is placed between the two snap-in positioning units 12 on the third side wall of the lower casing 1, so that the handle is restrained by the two snap-in positioning units 12 in the first direction. At the same time, the clamping and positioning units 12 on the first side wall and the second side wall of the lower shell 1 clamp and position the left end and the right end of the developing box, and further prevent the developing box from displacing relative to the packaging box in the first direction. The snap positioning units 12 on the third and fourth side walls of the lower casing 1 clamp the front and rear ends of the developing cartridge, respectively, so that the developing cartridge is restrained in the second direction, preventing the developing cartridge from being displaced in the second direction relative to the packing box. When the developing cartridge receives an external force parallel to the first direction or the second direction, the engagement positioning unit 12 can be compressed to absorb the impact, preventing the developing cartridge from being damaged.

The buffer unit 14 on the bottom surface of the lower casing 1 supports the bottom surface of the developing cartridge, and when the developing cartridge is subjected to an external force parallel to the third direction, the buffer unit 14 can be compressed in the third direction to absorb the impact, preventing the developing cartridge from being damaged.

And simultaneously, the cambered surface on the positioning part 24 is attached to the surface profile of the developing cartridge, and the developing cartridge is limited in the third direction under the limit of the positioning part 24 and the buffer unit.

In the process of covering the upper casing 2 on the lower casing 1, the engaging protrusion 23 interferes with the engaging wall 13, and since the upper casing 2 and the lower casing 1 are made of paper, the upper casing 2 and the lower casing 1 have elasticity, and the engaging protrusion 23 and the engaging wall 13 are elastically deformed under the interference, so that the engaging protrusion 23 can squeeze out the engaging wall 13 and enter the lower concave portion 11. When the engaging protrusion 23 enters the lower concave portion 11, the engaging wall 13 and the engaging protrusion 23 do not interfere, and the elastic deformation disappears. The engagement wall 13 blocks the engagement protrusion 23 from leaving the lower recess 11, thereby completing the combination of the upper case 2 and the lower case 1. And prevents the upper case 2 from being separated from the lower case 1.
