[0025] Example 2 The second embodiment of this utility model provides a packaging box that is easy to store. The stretching and folding mechanism includes a second movable connector 10. Two second movable connectors 10 are respectively fixedly connected to the front and rear ends of a fixed base plate 8. A second movable baffle 3 is provided at the upper end of the second movable connector 10. A second connector 18 is fixedly connected to the lower end of the second movable baffle 3. A first movable post 11 is provided inside the second movable connector 10. First through holes that cooperate with the first movable post 11 are opened on the left and right sides of the second movable connector 10. The second connector 18 and the second movable connector 10 are connected to each other. The first movable baffle 2 is movably connected via a first movable column 11. A baffle extension plate 4 is provided inside the second movable baffle 3. A first slide rail is fixedly connected to the front of the baffle extension plate 4. A positioning slot is provided on the inner side of the second movable baffle 3 to mate with the first slide rail on the baffle extension plate 4. Connecting rods 19 are fixedly connected to the left side of the second movable baffle 2 and the right side of the baffle extension plate 4, respectively. The connecting rods 19 are movably connected to the left and right sides of the first movable baffle 2. A locking mechanism is provided inside the baffle extension plate 4. The folding baffle mechanism includes a first movable connector 9 and two first movable connectors 9. The first movable connector 9 is fixedly connected to the left end of the fixed base plate 8 and the right end of the tension base plate 7, respectively. A second movable post 12 is provided inside the first movable connector 9, and a second through hole is opened inside the first movable connector 9 to cooperate with the second movable post 12. The second movable post 12 and the first movable connector 9 are movably connected through the second through hole. A first movable baffle 2 is provided on the top of the first movable connector 9, and a first connector 13 is fixedly connected to the bottom of the first movable baffle 2. The first connector 13 and the first movable connector 9 are movably connected through the second movable post 12. The cover plate tensioning mechanism includes a main... The main cover plate 1 covers the top edges of the first movable baffle 2 and the second movable baffle 3. The main cover plate 1 has a cover plate tension plate 5 inside, which is movably connected to the main cover plate 1. The bottom of the cover plate tension plate 5 is fixedly connected to a second slide rail. The main cover plate 1 has a first slide groove inside that cooperates with the second slide rail. The upper ends of the main cover plate 1 and the cover plate tension plate 5 have a movable slotted cover plate movable groove 6 that cooperates with the baffle tension plate 4. The bottom of the tension base plate 7 is provided with a third slide rail. The fixed base plate 8 has a second slide groove inside that cooperates with the third slide rail.

[0026] Specifically, the cover plate stretching mechanism, folding mechanism, and stretching-folding mechanism allow the user to open the packaging box by folding the second movable baffle 3. By adjusting the locking mechanism, the second movable baffle 3 is unlocked. Unlocking the second movable baffle 3 allows the packaging box to be stretched to the left and right. At the same time, the lengths of the fixed base plate 8 and the stretching base plate 7 can also be adjusted, and the length of the main cover plate 1 can also be adjusted appropriately. The design of the first slide rail and the slot effectively reduces the shaking of the baffle stretching plate 4 during stretching. The design of the second slide rail and the slide groove increases the stability of the cover stretching plate 5. The design of the third slide rail and the second slide groove increases the stability of the structure. When the user has unfolded the second movable baffle 3, the first movable baffle 2 is unfolded. The design of the second movable column 12 and the second movable connector 10 reduces friction during folding and improves the efficiency of space utilization.

[0027] Furthermore, when the user unfolds the packaging box, the second baffle is folded upwards. After the second baffle is folded, the first movable baffle 2 is folded, and the baffle extension plate 4 of the second movable baffle 3 is stretched. The stretched baffle extension plate 4 is locked by the locking mechanism. At the same time, the cover extension plate 5 on the main cover plate 1 and the extension bottom plate 7 on the bottom plate are adjusted and stretched to complete the unfolding of the packaging box. When the packaging box is retracted, the unlocking mechanism is unlocked. After unlocking, the stretched storage box is retracted and stretched back. The first movable baffle is folded downwards, and then the second movable baffle 3 is folded to complete the storage of the packaging box.

[0028] The parameters in the above content are as follows: the diameter of the first movable column 11 is 5mm (tolerance f6: -0.025 / -0.041mm), the diameter of the first through hole is machined according to H7 tolerance (+0.025 / 0mm), and the fit clearance is 0.025mm~0.066mm to ensure smooth rotation without jamming; The length of the stretching base plate 7 is set to L (e.g., 100mm). Its maximum sliding stroke relative to the fixed base plate 8 is ≥1.5L (i.e. ≥150mm). Therefore, the ratio of the maximum stretching stroke to the length of the base plate is ≥1.5:1, which meets the expansion requirements. The thickness of the fastening plate 16 is t=2mm±0.05mm, and the corresponding slot distance of the fastening slotted group 15 is P= t+0.3mm±0.05mm (i.e. 2.3mm±0.05mm). The slight interference fit ensures zero wobble after insertion and improves locking stability. 300g / m² white cardboard (0.4mm±0.03mm thick) covered with a 15μm PE film (waterproof coating) or 0.5mm±0.05mm PET plastic sheet (15μm PE film on the surface) can be used, both of which meet the requirements for waterproofing and structural strength. Made of injection-grade POM (polyoxymethylene), with a coefficient of friction ≤0.2 and a temperature range of -20℃ to 60℃, it is suitable for both normal temperature and low temperature logistics scenarios, ensuring smooth stretching. Example 3 The third embodiment of this utility model provides a packaging box that is easy to store. The locking mechanism includes a fastening screw 14, which is movably connected to the baffle tension plate 4 inside the baffle tension plate 4. The second movable baffle 3 has a circular hole inside that matches the fastening screw 14. The bottom of the circular hole has an internal thread that matches the fastening screw 14. The bottom of the second movable baffle 3 has a movable slot. The bottom of the fastening screw 14 has a fastening pressure plate 16, which is movably connected to the baffle tension plate 4. The bottom of the fastening pressure plate 16 has a spring 17 that is fixedly connected to the baffle tension plate 4. The bottom of the inner side of the second movable baffle 3 has a fastening slot assembly 15 that matches the fastening pressure plate 16.

[0029] Specifically, a locking mechanism is provided. During use, the user rotates the fastening screw 14, which moves up and down due to the action of the internal and external threads. When the fastening screw 14 moves downward, it presses down on the fastening plate 16, causing the fastening plate 16 to be pressed into the fastening slotted assembly 15, thus locking the stretching and folding mechanism. When the fastening screw 14 moves upward, the fastening plate 16 moves upward through the action of the spring 17, disengaging from the fastening slotted assembly 15, thus unlocking the stretching and folding mechanism. The design of the locking mechanism increases the stability of the packaging box itself.

[0030] Furthermore, when in use, the user rotates the fastening screw 14 inside the baffle tension plate 4. Due to the internal thread inside the baffle tension plate 4, the screw moves up and down. As the fastening screw 14 moves downward, it squeezes the fastening pressure plate 16 into the fastening slot at the bottom of the second movable baffle 3. The mechanical engagement locks the baffle tension plate. As the screw moves upward, the fastening pressure plate 16 is pushed upward by the spring 17, thus unlocking the baffle.

[0031] The parameters in the above content are as follows: Fastening screw 14: Specification is M3×0.5mm, ABS injection molded screw (surface roughness Ra≤1.6μm) or stainless steel 304 screw can be selected, and there is no breakage or stripping failure when the torque is ≥0.8N・m; Working principle: When the user opens the packaging box, the second baffle is folded upwards. After the second baffle is folded, the first movable baffle 2 is folded. After both sets of baffles are folded, the stretching baffle and stretching plate of the second movable baffle 3 are stretched. At the same time, the cover stretching plate 5 on the main cover plate 1 and the stretching bottom plate 7 on the bottom plate are adjusted and stretched. After stretching is completed, the fastening screw 14 inside the baffle stretching plate 4 is rotated. Due to the action of the internal thread inside the baffle stretching plate 4, the screw moves up and down. The fastening screw 14 moves downwards, squeezing the fastening pressure plate 16 into the first... Within the fastening slot at the bottom of the second movable baffle 3, the baffle is locked in place by mechanical engagement. Simultaneously, the cover plate extension plate 5 on the main cover plate 1 and the extension base plate 7 on the base plate are adjusted and extended to unfold the packaging box. When the packaging box is retracted, the screw moves upward, and the fastening pressure plate 16 is pushed upward by the spring 17 to unlock it. The stretched storage box is then retracted. The first movable baffle is folded downward, and then the second movable baffle 3 is folded down to complete the storage of the packaging box.

[0032] Performance test standards: (1) Load-bearing test: When the packaging box is unfolded, a 10kg weight is placed in the center of the main cover plate 1. After 24 hours, the maximum deflection of the main cover plate 1 is ≤2mm, and there is no visible permanent deformation (such as bending or cracking), ensuring load-bearing stability.

[0033] Fatigue test: After the baffle tension plate 4 is stretched 5000 times at a stroke of 0-100mm and a frequency of 20 times / min, the slide rail has no cracks or plastic deformation, and the locking force of the fastening pressure plate 16 (initial locking force ≥50N) decreases by ≤10%, ensuring long-term reliability. Drop test: A 1kg simulated object (a homogeneous object with a density of 1g / cm³) was placed inside the box and dropped freely from a height of 1m in six directions (up, down, front, back, left, and right). After the test, the locking mechanism did not come loose, and the box body (cover, baffle, and bottom plate) did not crack, meeting the impact resistance requirements for logistics transportation.

[0034] In summary, through the cooperation of the main cover plate 1, the first movable baffle 2, the second movable baffle 3, the baffle tension plate 4, the cover plate tension plate 5, the tension base plate 7, the fixed base plate 8, the first movable connector 9, the second movable connector 10, the first movable column 11, the second movable column 12, the first connector 13, the fastening screw 14, the fastening slotted assembly 15, the fastening pressure plate 16, the spring 17, the second connector 18, and the connecting rod 19, the effects of flexible storage, convenient operation, structural stability, and high space utilization are achieved.
