[0036] Implementation Method 1

[0037] A lifting box for split doors, such as Figure 1 As shown, it includes an inner box 1, an outer box 2, and a box sleeve 3; wherein, the box sleeve 3 is covered on the top of the inner box 1; the outer box 2 is set on the outside of the inner box 1 and the box sleeve 3, and connecting cardboard 4 is set between the left and right sides of the outer box 2 and the box sleeve 3; the box sleeve 3 is also provided with a through hole 5 for the product to pass through.

[0038] The outer box 2 includes two box covers 20 symmetrically arranged on the left and right sides of the inner box 1 and the box sleeve 3, and the two box covers 20 have the same structure; Figure 2 As shown, the box cover 20 includes a box cover body 201, an upper cover body 202, a lower cover body 203 and two side cover bodies 204, wherein the upper cover body 202 is connected to the upper side of the box cover body 201 in the length direction; the lower cover body 203 is arranged on the lower side of the box cover body 201 in the length direction; and the side length of the box cover body 201 in the length direction is equal to the side length of the upper cover body 202 and the lower cover body 203 in the length direction; the two side cover bodies 204 are symmetrically arranged on the other two sides of the box cover body 201; at the same time, the side length of the upper cover body 202 in the width direction is greater than the side length of the lower cover body 203 in the width direction, and the upper and lower sides of the side cover body 204 are respectively connected to the upper cover body 202 and the lower cover body 203, so that the box cover 20 has a right-angled trapezoidal structure. The outer box 2 also includes a connecting plate 21, which is fixedly connected to the outer side of the bottom of the inner box 1. The lower cover 203 is connected to the connecting plate 21 on a side away from the lid body 201. A crease line is provided at the location where the lower cover 203 and the connecting plate 21 are connected, allowing the lower cover 203 to be folded along the crease line. This allows the inner box 1 to be moved up and down during the opening and closing of the lid 20 via the connecting plate 21. The inner side of the lid body 201 is connected to the box sleeve 3 via a connecting card 4, allowing the box sleeve 3 to be moved up and down simultaneously during the opening and closing of the lid 20. In other embodiments, the outer box 2 may not include the connecting plate 21; in this case, the side of the lower cover 203 away from the lid body 201 needs to be connected to the bottom of the inner box 1, and a crease line is provided at the location where the lower cover 203 connects to the bottom of the inner box 1, so that the lower cover 203 can be folded along the crease line, thereby achieving the effect of driving the inner box 1 to move up and down during the opening and closing of the lid 20. In this embodiment, the outer box 2 is folded from a single piece of cardboard; in other embodiments, the outer box 2 can also be made of multiple pieces of gray board that are covered with a coating layer and then folded.

[0039] The connecting cardboard 4 is folded from the same piece of cardboard, and, as Figure 3As shown, the connecting paperboard 4 includes a buffer plate 41 and two card plates 42. The buffer plate 41 is provided with a buffer fold. The two card plates 42 are symmetrically arranged on either side of the buffer plate 41 in the longitudinal direction. The lengths of the two card plates 42 in the longitudinal direction are the same as the lengths of the buffer plate 41, while the widths of the two card plates 42 can be the same or different. The two card plates 42 are provided with fold lines at the locations where they connect to the buffer plate 41, so that both card plates 42 can be folded along the fold lines. The buffer plate 41 can act as a buffer during the folding process of the two card plates 42, preventing the two card plates 42 from breaking due to excessive tension when directly connected. When the two lids 20 of the outer box 2 are unfolded to the left and right sides, the card plate 42 fixedly connected to the box cover body 201 is folded to the left and right sides together with the box cover body 201 and pulled the box cover 3 downward by the buffer plate 41 and the other card plate 42 fixedly connected to the box cover 3, and when the two lids 20 are in the fully opened state, the box cover 3 can be dropped to the lowest point.

[0040] like Figure 4 As shown, the box cover 3 includes a cardboard body 31, two side panels 33, and two side wings 33. The two side panels 32 are symmetrically arranged on either side of the cardboard body 31 in the length direction, and the two side wings 33 are symmetrically arranged on either side of the cardboard body 31 in the width direction. Crease lines are provided between the two side panels 32 and the cardboard body 31, and between the two side wings 33 and the cardboard body 31. The end surface of the clamping plate 42 fixedly connected to the box cover 3 is fixedly connected to the outer surface of the side panels 32. In addition, a through hole 5 is provided in the cardboard body 31. In this embodiment, the box cover 3 is formed by folding a single piece of cardboard; in other embodiments, the box cover 3 can also be formed by folding multiple pieces of gray board covered with a coating layer.

[0041] The inner box 1 comprises a bottom plate body 11, two side plates 12 and two side wings 13; Figure 5As shown, the two side panels 12 are symmetrically arranged on either side of the base body 11 in the longitudinal direction; the two side wings 13 are symmetrically arranged on either side of the base body 11 in the width direction; crease lines are provided between the two side panels 12 and the base body 11, and between the two side wings 13 and the base body 11. In this embodiment, the inner box 1 is folded from a single piece of cardboard; however, in other embodiments, the inner box 1 can also be formed by folding multiple pieces of gray board covered with a coating layer.

[0042] When the double-door lifting box is in use, the product is placed in the inner box 1; when the left and right box covers 20 are folded downward, the side of the lower cover body 203 away from the box cover body 201 pushes the inner box 1 upward through the connecting plate 21, so that the inner box 2 moves upward. At the same time, the box cover body 201 pulls the box cover 3 downward through the connecting cardboard 4; when the left and right box covers 20 are fully opened, the inner box 1 rises to the highest point and the box cover 3 drops to the lowest point. At this time, the product placed in the inner box 2 can be displayed; after the display is completed, the left and right box covers 20 are folded in the opposite direction. At this time, the inner box 1 descends as the box covers 20 are folded, and the box cover 3 ascends as the box covers 20 are folded, and the product is automatically retracted into the inner box 1.
