[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-6The packaging box shown includes a packaging box body 1. A cabinet door 2 is provided on the side wall of the packaging box body 1, providing an opening for placing and removing a box 14. This facilitates the operator placing or removing the box 14 from the packaging box body 1. An ejector assembly is provided inside the packaging box body 1 to quickly eject and secure the box 14, improving the convenience of use and the efficiency of item retrieval. The ejector assembly includes a fixing frame 9 fixedly connected to the inner side wall of the packaging box body 1, which serves to install and support the ejector assembly. The related components provide installation space and a fixed base for components such as the limiting block 22 and the first spring 24. The limiting block 22 is slidably connected inside the fixed frame 9, and can slide within the fixed frame 9 to control the movement of the locking post 26, thereby realizing the locking and unlocking of the placement box 14. The first spring 24 is fixedly connected to the side wall of the limiting block 22, and the other end of the first spring 24 is fixedly connected to the inner side wall of the fixed frame 9. When the limiting block 22 is compressed by external force, the first spring 24 undergoes elastic deformation, storing elastic potential energy, which is released when the external force disappears. The elastic potential energy is released, pushing the limiting block 22 to reset. The first spring 24 acts as a buffer and reset mechanism. A limiting groove 23 is formed on the top of the limiting block 22. The limiting groove 23 is used to restrict the movement path of the locking post 26, allowing the locking post 26 to slide within the limiting groove 23, thus achieving engagement and disengagement with the placement box 14. A rotating rod 25 is rotatably connected to the inner side wall of the fixed frame 9. The rotating rod 25 can rotate around a fixed point, converting the linear motion of the limiting block 22 into the rotational motion of the locking post 26, thereby realizing the position change of the locking post 26. One end of the rotating rod 25 is fixedly connected to... There is a locking post 26, which slides inside the limiting groove 23. The locking post 26 is used to cooperate with the structure on the placement box 14 to realize the locking and fixing of the placement box 14. When the locking post 26 moves along the limiting groove 23 to the recess and locks in, the placement box 14 can be stably fixed in the packaging box body 1. The side wall of the limiting block 22 is fixedly connected to the linkage post 27, which passes through the fixing frame 9. The linkage post 27 is used to transmit the movement of the limiting block 22 to other components, realize the linkage between the components of the pop-out component, and thus control the pop-out and fixing process of the placement box 14.

[0020] Example 2: Reference Figure 1-6Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a connecting block 19 is fixedly connected to the bottom of the limiting block 22. The connecting block 19 is used to transmit the movement of the limiting block 22 and provides a basis for the movement transmission of components such as the first linkage rod 17. An inclined groove is provided on the side wall of the connecting block 19. The inclined groove is used to guide the movement of the second linkage rod 28. Through the special shape of the inclined groove, the linear movement of the second linkage rod 28 is converted into the deflection movement of the first linkage rod 17, realizing the linkage between components. A fixing rod 18 is fixedly connected to the bottom of the fixing frame 9. The fixing rod 18 provides a rotation fulcrum for the first linkage rod 17, ensuring that the first linkage rod 17 can rotate stably around one end. One end of the fixing rod 18 is rotatably connected to the first linkage rod 17. Used to transmit and convert the movement of the limiting block 22, driving the locking block 16 to move, realizing the locking and unlocking of the placement box 14. The side wall of the first linkage rod 17 is fixedly connected to the second linkage rod 28. The second linkage rod 28 slides in the inclined groove. By sliding in the inclined groove, the second linkage rod 28 associates the movement of the first linkage rod 17 with the movement of the connecting block 19, ensuring the coordination of the movement between the components. One end of the first linkage rod 17 is fixedly connected to the locking block 16. The locking block 16 is used to cooperate with the protrusion 15 on the placement box 14. When the locking block 16 and the protrusion 15 are engaged, the placement box 14 can be stably fixed in the packaging box body 1 to prevent the placement box 14 from shaking during transportation. The inner side wall of the packaging box body 1 is fixedly connected to the slide rail 6. The slide rail 6 is used to... The slider 5 provides a sliding track to ensure that the placement box 14 can slide smoothly inside the packaging box body 1, facilitating the placement and removal of the placement box 14. The slider 5 is slidably connected inside the slide rail 6, connecting the placement box 14 to the slide rail 6, allowing the placement box 14 to slide along the slide rail 6, and also distributing the weight of the placement box 14 to a certain extent. The placement box 14 is fixedly connected to the side wall of the slider 5. The placement box 14 is used to hold and protect items and is the core load-bearing component of the packaging box. The bottom of the placement box 14 is fixedly connected to a protrusion 15 that matches the locking block 16. The protrusion 15 cooperates with the locking block 16 to fix the placement box 14 inside the packaging box body 1, ensuring that the placement box 14 remains stable during transportation. A connecting shell is fixedly connected to the inner side wall of the packaging box body 1. 8. The connecting shell 8 is used to install and protect components such as the second spring 13 and the first linkage disc 12, providing them with a stable working space. The second spring 13 is fixedly connected to the inner side wall of the connecting shell 8. When the placement box 14 is placed and fixed, the second spring 13 is compressed and undergoes elastic deformation, storing elastic potential energy. When the placement box 14 needs to be removed, the elastic potential energy is released, pushing the placement box 14 out. The other end of the second spring 13 is fixedly connected to the first linkage disc 12, which slides inside the connecting shell 8. The first linkage disc 12 is used to transmit the elastic force of the second spring 13, converting the elastic potential energy of the second spring 13 into the kinetic energy to push the placement box 14. A moving column 11 is fixedly connected to the side wall of the first linkage disc 12, and the moving column 11 penetrates the connecting shell 8.The movable column 11 is used to transmit the movement of the first linkage disk 12 to the placement box 14, thereby transmitting the elastic force of the second spring 13. A second linkage disk 10 is fixedly connected to the side wall of the movable column 11. The second linkage disk 10 is used to connect the movable column 11 and the placement box 14, ensuring that the movement of the movable column 11 can be effectively transmitted to the placement box 14. This application also discloses a packaging liner, including a hollow shell 4, which is fixedly installed on the inner side wall of the placement box 14. The hollow shell 4 is used to install components such as a bidirectional threaded rod 20 and a movable block 21, protecting these components from external interference and providing them with working space. The bidirectional threaded rod 20 is rotatably connected inside the hollow shell 4. The bidirectional threaded rod 20 drives the movable block 21 to move along its axial direction by rotating, thereby realizing the adjustment of the position of the elastic inner liner plate 3. The two ends of the bidirectional threaded rod 20 are threadedly connected to the movable block 21, which is used to convert the rotation of the bidirectional threaded rod 20 into linear motion. The elastic inner liner 3 is moved to clamp and fix the items. The side walls of the moving block 21 are all fixedly connected with the elastic inner liner 3. The elastic inner liner 3 is used to clamp and fix the items in the placement box 14. It adapts to items of different sizes through its own elastic deformation and provides a stable fixing effect. One end of the bidirectional threaded rod 20 is fixedly connected to the rotating handle 7. The rotating handle 7 is used to facilitate the operator to rotate the bidirectional threaded rod 20. The position of the elastic inner liner 3 can be adjusted by manual operation. One end of the rotating handle 7 passes through the placement box 14 and the empty shell 4, which is convenient for the operator to operate outside the placement box 14.

[0021] The working principle of this utility model is as follows: When using the box, first open the cabinet door 2 and press the placement box 14 inward. The placement box 14 abuts against the linkage column 27, and the first spring 24 is compressed by the limiting block 22. At this time, the rotating rod 25 rotates, causing the locking column 26 to move along the limiting groove 23 to the recess and engage. While the limiting block 22 moves, the connecting block 19 moves together. The second linkage rod 28 will deflect the first linkage rod 17 along the inclined groove inside the connecting block 19, causing the locking block 16 to engage with the protrusion 15, so that the placement box 14 remains stable inside the packaging box body 1. While the placement box 14 remains stable, it will... The second linkage plate 10 causes the moving column 11 to squeeze the second spring 13 through the first linkage plate 12, so that the second spring 13 is in a compressed state. When it is necessary to remove the placement box 14, simply squeeze the placement box 14 into the inside of the packaging box body 1 again. The locking column 26 disengages from the recess, and the protrusion 15 and the locking block 16 are no longer locked. The second spring 13 returns to its original state and pushes the placement box 14 out through the second linkage plate 10. The placement box 14 can be completely removed along the slide rail 6. By rotating the rotating handle 7, the double-threaded rod 20 is used to bring the elastic inner lining plates 3 on both sides closer together to fix and clamp the placed items, providing protection.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
