Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, a hardware packaging carton is provided, including a hollow box body 1 and a top cover 2 that covers the top of the hollow box body 1. The inner cavity of the hollow box body 1 is provided with a cutter structure 3, which can divide the inner cavity of the hollow box body 1 into several cavities for placing hardware parts. It also includes a first layer plate 21 and a second layer plate 11. The first layer plate 21 is located on the top of the top cover 2 and has positioning protrusions 22 at both ends. The second layer plate 11 is located at the bottom of the hollow box body and has positioning recesses 12 corresponding to the positioning protrusions 22. Specifically, in this embodiment, 36 hollow boxes 1 are provided and stacked on a pallet 4 in a 3*3*4 pattern. The first layer plate 21 is used to increase the support strength of the top cover 2, and the second layer plate 11 is used to increase the support strength of the bottom of the hollow box 1. This can increase the stacking height to a certain extent. In addition, the positioning protrusions 22 and positioning recesses 12 raised in the vertical direction reduce the interval between each row of boxes, which can improve the neatness of the stacking.

[0032] In one embodiment of this utility model, such as Figure 4 As shown, the first layered board 21 includes three layers of first corrugated cardboard 23. The three layers of first corrugated cardboard 23 are stacked vertically and fixed with glue. The bottom layer of first corrugated cardboard 23 is fixed to the top of the top cover 2 with glue. The two ends of the remaining two layers of first corrugated cardboard 23 are respectively provided with first notches 231. The two first notches 231 are spliced ​​to form an assembly groove. The bottom of the positioning protrusion 22 is fixed in the assembly groove, and the top is exposed outside the assembly groove. Specifically, the assembly groove is rectangular and has an open outer end and a closed top end, which facilitates the assembly of the positioning protrusion 22. On the other hand, the concave assembly groove increases the contact area with the positioning protrusion 22 by utilizing a pair of sides, an inner side, and a bottom surface, which helps to improve the bonding stability of the positioning protrusion 22.

[0033] In one embodiment of this utility model, such as Figure 2As shown, the positioning protrusion 22 is right-angled and includes a connected horizontal section 221 and a vertical section 222. The horizontal section 221 is glued to the inner wall of the assembly groove, and the height of the vertical section 222 matches the depth of the positioning recess 12. Specifically, during stacking, the vertical section 222 of the right-angled positioning protrusion 22 is inserted into the upper positioning recess 12, which allows space to be reserved at the outer end of the positioning recess 12, thereby facilitating the separation of the stacked hollow box 1.

[0034] In one embodiment of this utility model, such as Figure 2 As shown, the length of the vertical segment 222 matches the length of the positioning recess 12, and its width is 0.3 to 0.6 times the width of the positioning recess 12. Specifically, the width of the vertical segment 222 is 0.5 times the width of the positioning recess 12, so as to reserve space at the outer end of the positioning recess 12. On the other hand, it avoids insufficient positioning performance due to the vertical segment 222 being too thin. In this embodiment, the positioning recess 12 is rectangular in shape and has open outer and bottom ends. When stacking, the inner end faces of a pair of vertical segments 222 act on the inner side surfaces of the positioning recess 12, thereby preventing adjacent boxes from shifting in the length direction. The pair of side surfaces of the vertical segments 222 act on the pair of side surfaces of the positioning recess 12, thereby preventing adjacent boxes from shifting in the width direction.

[0035] In one embodiment of this utility model, such as Figure 2 As shown, the inner side of the top end of the vertical segment 222 is provided with a chamfer facing the positioning recess 12. The chamfer facilitates the insertion of the vertical segments into the positioning recess 12 during stacking and reduces the possibility of the top end of the vertical segment 222 scratching the top edge of the positioning recess 12.

[0036] In one embodiment of this utility model, the positioning protrusion 22 is made of plastic material. Specifically, the positioning protrusion 22 is injection molded from PC material.

[0037] In one embodiment of this utility model, such as Figure 4 As shown, the second layer board 11 includes four layers of second corrugated cardboard 13. The four layers of second corrugated cardboard 13 are stacked vertically and fixed with glue. The top layer of second corrugated cardboard 13 is fixed to the bottom of the hollow box 1 with glue. The two ends of the remaining three layers of second corrugated cardboard 13 are respectively provided with second notches 131. The three second notches 131 are spliced ​​together to form the positioning recess 12. By using the stacked four layers of second corrugated cardboard 13, the depth of the positioning recess 12 in the vertical direction is increased, thereby increasing the contact surface with the vertical section 222 of the positioning protrusion 22, which is beneficial to improving the positioning effect of the box.

[0038] In one embodiment of this utility model, such as Figure 4 As shown, the knife-holding structure 3 includes a plurality of first knife-holdings 31 and two second knife-holdings 32. The plurality of first knife-holdings 31 are arranged at equal intervals in the inner cavity of the hollow housing 1. The two second knife-holdings 32 are respectively located at both ends of the plurality of first knife-holdings 31. The top of the plurality of second knife-holdings 32 has a first slot corresponding to each of the first knife-holdings 31, and the bottom of the plurality of second knife-holdings 32 has a second slot corresponding to each of the second knife-holdings 32. Specifically, there are a total of 10 first knife-holdings 31, which can create 9 spaces in the inner cavity of the hollow housing 1 for placing hardware parts.

[0039] In one embodiment of this utility model, such as Figure 1 As shown, it also includes a tray 4, on which several hollow boxes 1 are stacked. The bottom of the tray 4 is provided with support feet that abut against the external bearing surface. Hollow slots 14 are respectively provided at both ends of each hollow box 1. The hollow slots 14 provide a point of leverage for manual handling.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
