[0002] As the name implies, a packaging box is a box used to package products. It can be classified by material, such as: paper box, iron box, wooden box, cloth box, leather box, acrylic box, corrugated packaging box, PVC box, etc. Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. However, after the products are packaged, the cartons used in life are stacked together for storage or transportation. Since the top of the carton is usually a simple flip stack of cardboard, when the top of the carton is subjected to pressure, it is easy to have local dents or deformation, which will seriously affect the appearance of the product packaging and easily cause the products placed inside the carton to be squeezed. For this reason, the present application proposes a packaging box with a pressure-resistant structure. Utility Model Content

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Depend on Figure 1-5The utility model includes a box body 1, which is a rectangular upper opening structure. A reversible first sealing plate 2 is fixedly installed on the top of both ends of the box body 1, and a reversible second sealing plate 3 is fixedly installed on the top of both sides of the box body 1. Support card plates 4 are fixedly installed on the bottom of both sides of the inner wall of the box body 1, and there is a gap between the lateral side plates of the two support card plates 4 and the inner wall of the box body 1. Connecting card plates 5 are fixedly installed at the middle positions of the two ends of the inner side of the first sealing plates 2 on both sides. When the first sealing plate 2 is flipped to a horizontal state, the connecting card plates 5 on both sides of the inner wall of the first sealing plate 2 can be inserted into the gap between the corresponding supporting card plates 4 and the inner wall of the box body 1. A supporting plate 6 is arranged at the opening at the top of the box body 1, and the two ends of the supporting plate 6 are vertical, and the vertical parts at both ends of the supporting plate 6 can be inserted into the gap between the two supporting card plates 4 and the inner wall of the box body 1.

[0020] like Figure 4 and Figure 5 As shown, a grid-like frame 7 is provided inside the two first sealing plates 2 and the two second sealing plates 3. The grid frame 7 inside the first sealing plates 2 and the two second sealing plates 3 can greatly improve the hardness of the first sealing plates 2 and the two second sealing plates 3, making them less likely to deform and providing a good compression resistance effect.

[0021] like Figure 1 and Figure 2 As shown, the lengths of the two first sealing plates 2 are each one-fourth of the length of the box body 1, and the widths of the two second sealing plates 3 are the same as the width of the box body 1, so that the two second sealing plates 3 on the top of the box body 1 can cover the tops of the two first sealing plates 2 in sequence, so that the two second sealing plates 3 will not be joined on the top of the box body 1, thereby preventing the second sealing plates 3 from sinking.

[0022] like Figure 1 As shown, the width of the support plate 6 is the same as the width of the box body 1, the length of the support plate 6 is greater than half of the length of the box body 1, and the width of the support plate 6 is less than the distance between the two connecting card plates 5 on the same side when the two first closing plates 2 are in a horizontal state. After the support plate 6 is inserted between the two support card plates 4, the support plate 6 can support the ends of the two first closing plates 2 away from the box body 1, and the connecting card plates 5 on the first closing plates 2 can be smoothly inserted into the corresponding supporting card plates 4, so that the two first closing plates 2 can stably maintain a horizontal state, thereby allowing the two first closing plates 2 to support the two second closing plates 3.

[0023] like Figure 1 and Figure 2 As shown, the tops of the two supporting plates 4 and the top of the box body 1 are located at the same water surface.

[0024] like Figure 4 and Figure 5As shown, the grid frame 7 is made of hard plastic material, and the area of ​​the grid frame 7 covers the entire first closing plate 2 and the second closing plate 3, so that the grid frame 7 has good hardness without increasing much weight.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
