[0027] Example

[0028] Reference Figure 1-Figure 6 The utility model provides a technical solution: a folding linkage packaging box, including a bottom box 1 and a packaging box assembly 3, the top cover 2 is rotatably installed on the bottom box 1, the packaging box assembly 3 includes a connecting belt 31, one end of the connecting belt 31 is fixedly installed on the inner wall of the bottom box 1, the other end of the connecting belt 31 is fixedly installed on the inner wall of the top cover 2, a protective plate 32 is rotatably installed inside the bottom box 1, one end of the protective plate 32 is fixedly installed with a lifting belt 321, a placement plate 33 is installed inside the bottom box 1, and the protective plate 32 is arranged above the placement plate 33.

[0029] In a preferred embodiment, a decoration 4 is installed on the outer surface of the protective plate 32, and the decoration 4 is arranged on the inner side of the top cover 2. In order to enhance the aesthetics of the device, the decoration 4 is installed on the protective plate 32. In actual use, when the top cover 2 is opened, the decoration 4 will be displayed in front of the eyes, thereby enhancing the sense of luxury and beauty and satisfying the use.

[0030] In a preferred embodiment, a groove 5 is provided on the upper surface of the bottom box 1, and the interior of the groove 5 is plugged with a placement plate 33, and a placement groove 6 is provided on the upper surface of the placement plate 33. In order to facilitate placing items into the interior of the bottom box 1, the device is provided with a groove 5 inside the bottom box 1, and a placement plate 33 is installed inside the groove 5, and a placement groove 6 is provided on the placement plate 33, and a sponge strip 7 is fixedly installed inside the placement groove 6. Two sponge strips 7 are provided and are installed inside the placement groove 6 in a vertical manner.

[0031] In a preferred embodiment, the decoration 4 includes a decorative plate 41, a rotating wheel 42, a torsion spring 43 and a pull rope 44. The bottom surface of the decorative plate 41 is fixed with a rotating wheel 42, and a torsion spring 43 is installed between the rotating wheel 42 and the protective plate 32. A through hole 45 is opened inside the protective plate 32. The free end of the pull rope 44 passes through the through hole 45 and is fixedly connected to the top cover 2. The other end of the pull rope 44 is connected to the rotating wheel 42. When in use, the top cover 2 is opened to drive the pull rope 44, and then the pull rope 44 will drive the rotating wheel 42 to rotate, thereby driving the decorative plate 41 to rotate, which can greatly improve the aesthetics. When the top cover 2 is closed, the torsion spring 43 will wrap the pull rope 44 around the side of the rotating wheel 42, so as to facilitate the normal driving of the decorative plate 41 to rotate next time.

[0032] In actual use, two sponge strips 7 are vertically installed inside the placement groove 6 to isolate four spaces, so that items can be placed in the corresponding spaces. Since the sponge strips 7 have a certain degree of softness, they can prevent the items from being squeezed and deformed to affect the appearance of the items, and can also protect the items for easy use.

[0033] In order to reduce the space occupied by the top cover 2 after it is unfolded and to connect it with the bottom box 1, two connecting belts 31 are set and evenly installed on the inner wall of the bottom box 1. One end of the two connecting belts 31 is fixedly connected to the inner wall of the top cover 2. After the top cover 2 is opened, the top cover 2 will not rotate excessively under the pull of the connecting belts 31, so that the top cover 2 and the bottom box 1 can be in a vertical state, reducing the space occupied.

[0034] In order to facilitate the protection of articles, the device has the top cover 2 rotatably connected to the bottom box 1 through the hinge 8, and the width of the top cover 2 is matched with the width of the bottom box 1, and the lifting belt 321 is arranged on the outside of the top cover 2, and the lifting belt 321 is used to pull the protective plate 32 to rotate. After placing the articles, the top cover 2 can be placed on the bottom box 1, and the top cover 2 and the bottom box 1 are completely fitted, which can protect the articles and prevent air impurities from the outside from entering the bottom box 1 and causing pollution to the articles. At the same time, the lifting belt 321 is arranged on the outside of the top cover 2, which is convenient for opening the protective plate 32 and driving the top cover 2 to open, so as to facilitate use.

[0035] Specifically, the working process or working principle of a folding linkage packaging box is as follows: most of the current packaging boxes are composed of a bottom box 1 and a top cover 2. Some of the top cover 2 and the bottom box 1 are provided with a snap connection, and some are provided with a rotating connection. By opening the top cover 2, the items can be placed inside the bottom box 1 to achieve storage of the items. However, in actual use, the packaging boxes will be squeezed during stacking or transportation, and the squeezing will easily cause the top cover 2 to deform and concave inward, which will squeeze the items, causing the items to break and deform, affecting the appearance. Therefore, this device is designed to solve this problem.

[0036] By using this device, objects can be protected from damage. When using this device to load objects, the top cover 2 is opened. The top cover 2 is formed into a whole with the bottom box 1 under the action of the connecting belt 31, and the top cover 2 can be limited under the pulling of the connecting belt 31 to prevent the top cover 2 from falling off and excessively unfolding to occupy space. Then the protective plate 32 is opened. This device connects the protective plate 32 to the bottom box 1 through a cloth strip, which can make the protective plate 32 rotate easily. After the protective plate 32 is opened, the placement plate 33 will be exposed, and the objects are placed in the space surrounded by the sponge strip 7 and snapped into the space. The sponge strip 7 is used to limit and protect the objects.

[0037] After the items are placed, the protective plate 32 is covered on top of the items, leaving a certain space between the top of the items and the protective plate 32, which effectively prevents the top cover 2 from squeezing the products when it is squeezed. The protective plate 32 can protect the items from damage, and finally the top cover 2 can be covered on the bottom box 1.
