[0021] Reference Figure 1 , Figure 3 , Figure 6 Positioning components are provided at the four corners of the packaging box 1. Each positioning component includes a fixing sleeve 2. An arc-shaped groove is formed at each of the four corners of the packaging box 1, and the fixing sleeve 2 is fixedly connected to each of the four corners. The fixing sleeve 2 supports and protects the four corners of the packaging box 1, and provides an installation base for the positioning post 7 and the positioning groove 8. The bottom of the fixing sleeve 2 is fixedly connected to the positioning post 7, which cooperates with the positioning groove 8 of the lower packaging box 1 to achieve precise positioning during stacking. The top of the fixing sleeve 2 has a positioning groove 8, which is used to engage with the positioning post of the upper packaging box 1. 7. To ensure stacking stability, the bottom of the fixing sleeve 2 is fixedly connected to a positioning post 7. The top and bottom of the positioning post 7 are fixedly connected to rubber rings 4 respectively. The rubber rings 4 play a role in buffering and anti-slip, reducing hard contact between the positioning post 7 and the positioning groove 8, preventing wear, and increasing friction. The bottom of the positioning post 7 is set with a slope, and the inner wall of the positioning groove 8 is set with a slope. The bottom of the positioning post 7 is adapted to the inner wall of the positioning groove 8. The slope design makes it easy for the positioning post 7 to be inserted into the positioning groove 8, and at the same time, it automatically corrects the position during the stacking process to ensure the stability of the packaging box 1.
[0022] Reference Figure 4 , Figure 5The snap-fit assembly includes a handle 6, the back of which is fixedly connected to the front of the inner box 5. The handle 6 provides a force point for the operator to operate the snap-fit assembly by pulling the handle 6. The inner side of the handle 6 contacts a pinch plate 10, which is used to control the extension and retraction of the insertion rod 17 by pinching. The inner wall of the handle 6 has a groove 15, which provides a sliding track for the slider 14, ensuring that the slider 14 can slide smoothly along a predetermined path. The slider 14 is fixedly connected to both sides of the pinch plate 10, and the slider 14 slides against the inner wall of the groove 15. The slider 14 slides within the groove 15, transmitting the motion of the pinch plate 10 to the pull rope 12. The pull rope 12 is fixedly connected to the back of the pinch plate 10. The end of the pull rope 12 extends through the front of the inner box 5 and is fixedly connected to the insertion rod 17. The pull rope 12 transmits the motion of the pinch plate 10 to the insertion rod 17 and controls the extension and retraction of the insertion rod 17. The inner wall of the inner box 5 is rotatably connected to a pulley 13. The surface of the pull rope 12 contacts the surface of the pulley 13. The pulley 13 changes the direction of movement of the pull rope 12, reducing the friction of the pull rope 12 during movement.
[0023] Reference Figure 4 , Figure 5 The inner box 5 has movable slots on both sides, which provide sliding space for the insertion rod 17 and restrict its movement direction. The surface of the insertion rod 17 is slidably connected to the inner wall of the movable slot. The insertion rod 17 is used to insert into the slot to fix the inner box 5, or to pull out of the slot to release the inner box 5. One end of the insertion rod 17 is elastically connected to the inner wall of the movable slot through a spring B16. The spring B16 provides elastic support for the insertion rod 17, allowing it to automatically return to its original position. One end of the spring B16 is fixedly connected to the inner wall of the movable slot. The other end of 16 is fixedly connected to the end of the insert rod 17. Slots are provided on the inside of both sides of the packaging box 1. The slots are used to cooperate with the insert rod 17 to fix the inner box 5. The other end of the insert rod 17 abuts against the inner wall of the slot. The front of the pinch plate 10 is elastically connected to the inner wall of the handle 6 through the spring A11. The spring A11 provides elastic support for the pinch plate 10, so that the pinch plate 10 can automatically return to its original position. One end of the spring A11 is fixedly connected to the front of the pinch plate 10, and the other end of the spring A11 is fixedly connected to the inner wall of the handle 6.
[0024] Working principle: Place packaging box 1 on top of another packaging box 1, align the positioning pin 7 with the positioning groove 8 of the lower packaging box 1, and gently lower packaging box 1. The positioning pin 7 and the positioning groove 8 cooperate to complete the positioning. The inclined surface at the bottom of the positioning pin 7 fits against the inclined surface of the inner wall of the positioning groove 8 to ensure the stability and accuracy of stacking. Place the inner box 5 inside the packaging box 1. The movable grooves on both sides of the inner box 5 are aligned with the slots on both sides of the packaging box 1. At this time, the insertion rod 17 is extended under the action of spring B16 and inserted into the slot to fix the inner box 5 inside the packaging box 1.
[0025] When it is necessary to remove a certain inner box 5 from the stacked packaging boxes 1 for random inspection, first pinch the pinch plate 10. The pinch plate 10 slides in the slide groove 15 through the slider 14, which drives the pull rope 12 to move. The pull rope 12 pulls the insertion rod 17 to overcome the elastic force of the spring B16, so that the insertion rod 17 is pulled out from the slot. At this time, the inner box 5 is separated from the packaging box 1, and the inner box 5 can be easily taken out for inspection.
[0026] After the sampling inspection is completed, put the inner box 5 back into the packaging box 1, ensuring that the movable groove is aligned with the slot. Release the pinch plate 10, the spring B16 releases its elastic potential energy, pushes the plug rod 17 back into the slot, fixes the inner box 5 inside the packaging box 1, and restores the integrity of the packaging box 1. When the packaging box 1 needs to be moved, remove the handle 3 from the storage slot 18, hold the handle 3 to move it, and after moving it, put the handle 3 back into the storage slot 18 to keep the appearance of the packaging box 1 clean.
