Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise; in addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Referring to the attached drawing 1, the wine packing box is that box bottom and box body are connected and are formed, box bottom and box body are connected with the riveting form after punching commonly used, the box bottom comprises bottom plate 10 and coupling frame 20, bottom plate 10 and coupling frame 20 often adopt and scribble the mode viscose of smearing the viscose on bottom plate 10 and connect, but because the wine weight of placing in the wine packing box is big, when using, the user is used to singlehanded and gets wine, the condition that bottom plate and coupling frame degum often appears, thereby lead to the wine to drop, consequently there is poor stability, the defect that joint strength is low in the bottom plate and the coupling frame viscose connection of box bottom.

As shown in fig. 2 and fig. 3, the embodiment of the present invention provides a bottom of a packing box, including a rectangular bottom plate 10 and a rectangular connecting frame 20, the bottom plate 10 and a boss 21 for connecting the box body is formed between the connecting frames 20, and further including a folding paperboard 30 adhered to the surfaces of the bottom plate 10 and the connecting frame 20, the folding paperboard 30 includes a connecting bottom 31 adapted to the bottom plate 10, and four connecting pieces 32 connected to four sides of the connecting bottom 31, the connecting pieces 32 include a boss portion 33 adapted to the boss 21 and a first connecting portion 34 connected to the boss portion 33, two corners of the outer end of the first connecting portion 34 have 45 ° chamfers, and the outer end of the first connecting portion 34 is connected to a second connecting portion 35.

In the folded paperboard 30 covering the bottom panel 10 and the connecting frame 20, the connecting portions of the connecting bottom 31 and the boss portion 33, the boss portion 33 and the first connecting portion 34, and the first connecting portion 34 and the second connecting portion 35 are positions where creases are generated, and the creases may be temporarily folded at the time of assembly or may be previously folded before assembly, according to the common knowledge in the field of packaging cartons; in the description of the present invention, the foldable cardboard 30 should be understood in a colloquial manner as a paper layer coated on the surface of the bottom plate 10 and the connecting frame 20, the foldable cardboard is not a cardboard characterized by having a sufficient thickness, and may be a cardboard having a considerable thickness or a thin paper sheet according to the thickness, and the outer paper layer functioning as fixing, decoration, etc. is included in the cardboard; and simultaneously, the utility model discloses in do not have specific restricted material to the folding cardboard of bottom plate, linking frame and bonding bottom plate and linking frame, its material can include art paper, carbon paper, cover paper etc..

In the above-mentioned scheme, through increasing folding cardboard 30 to through folding cardboard 30 bonding bottom plate 10 and linking frame 20, make the connection of bottom plate 10 and linking frame 20 change into the bonding of enclosing entirely by direct bonding, bonding strength is higher, makes bottom plate and linking frame form one whole, has improved the bulk strength of box bottom, has improved the reliability and the intensity of box bottom, has solved the box bottom and has appeared "falling the end" problem after being connected with the box body easily.

In a preferred embodiment, the two corners of the outer end of the boss portion 33 are chamfered at 45 °. The chamfer of the outer ends of the boss parts 33 enables the chamfer surfaces of the four boss parts 33 to form boss surfaces equivalent to the bosses 21 during bonding, so that the bonding of the bosses at the joint of the bottom plate 10 and the connecting frame 20 is smoother, and no overlapped step surface is generated, thereby facilitating the connection of the box body and the box bottom.

In a preferred embodiment, a pressing piece 36 is connected to each of the four sides of the second connecting portion 35, and the four pressing pieces 36 are connected to the same side of the second connecting portion 35. The effect of compressing tightly piece 36 is further strengthens joint strength, and when the equipment, clockwise or anticlockwise with this bond four second connecting portion 35 and compressing tightly piece 36 on the internal wall face of linking frame 20, during the bonding with compressing tightly piece 36 is compressed tightly by second connecting portion 35 and is regarded as the standard on the inner wall of linking frame 20, makes like this and forms horizontal interact between four independent second connecting portion 35, guarantees the joint strength, improves the bulk strength and the stability of bottom plate 10 and linking frame 20.

In a preferred embodiment, the width of the boss portion 33 is the same as the thickness of the base plate 10, the chamfered width of the boss portion 33 is the same as the width of the boss 21, and the chamfered width of the first connecting portion 34 is the same as the thickness of the wall plate of the connecting frame 20. When the sizes of all parts on the connecting sheet 32 are the same, the connecting sheet 32 is bonded to the bottom plate 10 and the connecting frame 20 to form a tight whole, the connecting strength is highest, the packaging effect is best, and particularly, the whole box bottom and the box body are convenient to connect at the later stage.
