[0002] A packaging box is a container used to package and protect goods. It also plays a role in promoting and selling products. Packaging boxes can be made of cardboard, plastic, metal and natural materials.

[0003] When packaging fragile items in existing packaging boxes, partitions are usually installed around the fragile items to limit the position of the fragile items in the packaging box to prevent the fragile items from constantly colliding with the inner wall of the packaging box and being damaged during transportation. However, when the volume and shape of the fragile items change, the partitions need to be taken out, and the fragile items need to be adjusted to a suitable position before the partitions are loaded again to ensure that the partitions can limit the items. Each time the volume and shape of the items change, the partitions need to be taken out and reloaded, which is inconvenient to use. Utility Model Content

[0027] Reference Figure 1A packaging box support structure includes a packaging box body 1, a first support member 2 is arranged in the packaging box body 1, and an inner side wall of the packaging box body 1 is provided with a mounting groove 3, both ends of the first support member 2 are slidably embedded in the mounting groove 3, and both ends of the first support member 2 are further provided with second support members 4, the second support member 4 can be detachably pressed against the inner side wall of the packaging box body 1, and one end is hinged to the first support member 2, and the other end is hinged to a third support member 5, the two third support members 5 extend to the middle of the first support member 2 and press against each other, so that two connected right-angled triangles can be formed on both sides of the commodity, wherein the first support member 2 and the second support member 4 are respectively pressed against the packaging box as right-angled sides The side and bottom surfaces of the main body 1, the third support member 5 is connected between the first support member 2 and the second support member 4 as a hypotenuse. At this time, the four triangles can form an internal support structure in the packaging box main body 1 to prevent the packaging box main body 1 from being deformed and collapsed due to extrusion during transportation. At the same time, since the two ends of the first support member 2 are embedded in the installation groove 3, the second support member 4 is hinged to the positions of the two ends of the first support member 2 outside the installation groove 3, the first support member 2 can only slide on the bottom surface of the packaging box main body 1, and the first support member 2 stands on the bottom surface of the packaging box main body 1 as a triangle, so that the triangle can stably maintain its supporting effect, and the goods can be stably clamped to prevent the goods from tipping over.

[0028] In a specific embodiment, when there is no product packaged or there is no need to limit the position of the product, the first support member 2, the second support member 4 and the third support member 5 are stacked together and stored at the inner corner of the packaging box body 1 to avoid them occupying more space in the packaging box, and the product can be directly placed on top of the first support member 2, the second support member 4 and the third support member 5. After the product is placed in the packaging box body 1, the first support member 2 is slid to make it abut against both sides of the product, and then the second support member 4 is rotated to make it abut against the inner wall of the packaging box body 1, and finally the third support member 5 is rotated toward the middle of the first support member 2 so that the two third support members 5 abut against each other. At this time, two connected triangles can be formed. After the triangle is formed, it is pressed toward the product to make it close to the side of the product to ensure that it can support the product.

[0029] A triangle is the simplest rigid structure. Unless the external force is large enough to destroy the structure, the triangle can maintain its shape when subjected to external force. When subjected to external force, the stress of the triangle will be evenly distributed to the three corners and three sides, which helps to disperse and balance the force, making the structure more stable. At the same time, the triangle has a strong ability to resist distortion and can avoid deformation when subjected to diagonal forces. Therefore, the triangle shape formed by the first support member 2, the second support member 4 and the third support member 5 can further enhance the support of the packaging box body 1.

[0030] Reference Figure 1 and Figure 2 An arc-shaped concave surface is provided in the middle of the first support member 2, and the two third support members 5 are against the lowest point of the arc-shaped concave surface. Under such a setting, the arc-shaped concave surface can not only play a guiding and positioning role, so that the third support member 5 can quickly abut against the middle of the first support member 2, and because the third support member 5 is located at the lowest point of the arc-shaped concave surface at this time, it is necessary to climb upward to escape from the arc-shaped concave surface. When the packaging boxes are stacked, the third support member 5 can only convert the force applied to it into a vertical downward force. Therefore, it is difficult for the third support member 5 to escape from the arc-shaped concave surface independently without human control. The arc-shaped concave surface can also play a limiting role.

[0031] In a specific embodiment, the first support member 2, the second support member 4 and the third support member 5 are all made of metal materials with certain elasticity and toughness, including but not limited to aluminum, so as to extend the service life of the first support member 2, the second support member 4 and the third support member 5, and reduce the probability of them being completely deformed or even broken due to long-term heavy pressure.

[0032] Reference Figure 1 and Figure 2 Two limit shafts 6 are penetrated in the arc-shaped concave surface of the first support member 2, and through holes 7 for the limit shafts 6 to pass through are opened at one end of the two third support members 5 facing the first support member 2. Under such an arrangement, when the third support members 5 are against the arc-shaped concave surface, the limit shafts 6 are inserted into the through holes 7 to further prevent the third support members 5 from independently detaching from the arc-shaped concave surface during transportation.

[0033] Reference Figure 1 and Figure 3 In order to better operate the limit shaft 6, a connecting piece 8 is fixed between the two limit shafts 6. Under this arrangement, the limit shaft 6 is penetrated with the connecting piece 8 as the force application point, which is convenient for the staff to directly control the two limit shafts 6 to penetrate the through holes 7, and at the same time, the volume of the components can be increased to prevent loss.

[0034] Reference Figure 1 The first support member 2 and the third support member 5 are located in the same plane in the longitudinal direction and are arranged on the side of the second support member 4 facing the product. In this arrangement, the first support member 2 and the third support member 5 are both in contact with the side of the product, which can further enhance their supporting effect on the product.

[0035] Reference Figure 1-Figure 3 , an embodiment of the utility model further provides a packaging box, comprising the packaging box supporting structure as described above.

[0036] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0037] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
