[0023] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0024] Please see Figures 1-5 As shown, the multifunctional plastic packaging box of this utility model includes a box body 1, a storage box 2 is provided inside the box body 1, a limiting plate 4 is provided on the lower end face of the storage box 2, a limiting groove 11 is provided at both ends of the limiting plate 4, a limiting rod 10 is provided inside the limiting groove 11, one end of the limiting rod 10 is installed on the storage box 2, a driving component is provided between the limiting plate 4 and the storage box 2, a sliding groove 3 is provided on the inner wall of the box body 1 at the corresponding position of the limiting plate 4, a through hole is provided on one side of the box body 1 of the storage box 2, an elastic component is provided on one side of the box body 1, and a limiting component is provided on the other side of the box body 1.

[0025] like Figure 4 As shown, the drive assembly includes a drive rod 5, which is slidably mounted on the storage box 2. A spring 6 is sleeved on the drive rod 5. One end of the spring 6 is fixedly connected to the limiting plate 4, and the other end of the spring 6 is fixedly connected to the storage box 2. By controlling the movement of the drive rod 5, the drive rod 5 drives the limiting plate 4 to move accordingly. While the limiting plate 4 is moving, it compresses and stores force on the spring 6. The release force of the spring 6 pushes the limiting plate 4 to reset, and the limiting plate 4 drives the drive rod 5 to reset accordingly.

[0026] In this embodiment, the drive assembly also includes a rotating shaft 7, which is rotatably mounted on the storage box 2. A gear 8 is mounted on the rotating shaft 7, and a rack 9 is meshed on one side of the gear 8. One end of the rack 9 is mounted on the drive rod 5. The rack 9 is slidably disposed with the storage box 2. The operator drives the rotating shaft 7 to rotate, which in turn drives the gear 8 to rotate. The gear 8 drives the internally meshed rack 9 to move, and the rack 9 drives the drive rod 5 to move synchronously.

[0027] Combination Figure 2 , Figure 3 As shown, the elastic component includes a second spring 14 and a push plate 13. The push plate 13 is disposed between the storage box 2 and the housing 1, and the second spring 14 is disposed between the push plate 13 and the housing 1. A telescopic rod is provided inside the second spring 14. The two ends of the telescopic rod are fixedly connected to the push plate 13 and the housing 1, respectively. The telescopic rod restricts the movement direction and position of the push plate 13, thereby improving the stability of the push plate 13 during operation.

[0028] like Figure 1 , Figure 3 As shown, the limiting component includes a baffle 12, which is rotatably mounted on the housing 1. The side of the baffle 12 that is inserted into the storage box 2 is chamfered. The baffle 12 restricts the position of the storage box 2, thereby preventing the storage box 2 from moving directly out of the through hole.

[0029] like Figure 5 As shown, a triangular block 15 is installed on the lower end face of the storage box 2. The triangular block 15 is located on the side close to the push plate 13. The triangular block 15 and the push plate 13 are slidably arranged. When the storage box 2 is placed into the box 1 and descends, the storage box 2 drives the push plate 13 to move through the triangular block 15. The push plate 13 drives the spring 14 to compress and store force.

[0030] Looking back Figure 2 As shown, a cover plate 16 is provided on the top of the storage box 2. The cover plate 16 is snapped into the storage box 2. When an item is placed in the storage box 2, the cover plate 16 is snapped into the storage box 2 to prevent the item from exceeding the storage space of the storage box 2 and affecting the subsequent removal of the storage box 2 from the side.

[0031] The implementation principle is as follows: When the storage box 2 needs to be placed into the box 1, the rotating shaft 7 is driven to rotate, which drives the gear 8 to rotate. The gear 8 drives the rack 9 to move, and the rack 9 drives the limiting plate 4 to move and retract through the driving rod 5. At the same time, the limiting plate 4 pushes the spring 6 to compress. Then, the storage box 2 is placed into the box 1 and moved to the preset position. Then, the operator releases the rotating shaft 7 and pushes the limiting plate 4 to move under the action of the rotating shaft 7, which cooperates with the slide 3 to restrict the storage box 2. When the storage box 2 needs to be removed from one side, the operator drives the baffle 12 to rotate to release the restriction on the storage box 2. Under the cooperation between the push plate 13 and the spring 14, one end of the storage box 2 is pushed out of the through hole. Then, the operator can directly remove the storage box 2.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
