Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a portable packaging box. Background Art

[0002] With the continuous development of Internet technology, e-commerce shopping is becoming more and more popular among people, and more and more large and small items are bought online. After that, the express company will package the items and transport them to the hands of the buyers.

[0003] For example, a Chinese patent discloses: a convenient plastic packaging box, patent number: CN214241941 U, which can save time during the transportation of the packaging box by setting a pulley, and can accommodate the second pressure plate, the fixing rod and the first pressure plate by setting the packaging box. By cooperating with the packaging box, the box cover, the switch, the first pressure plate and the second pressure plate, objects can be placed in the box to fix the objects. Even if a collision occurs during transportation, the objects will not be damaged. By setting a switch to open and close the packaging box and the box cover, the objects can be stored, which solves the problem that small objects are easily damaged in the packaging box, difficult to transport, and increase transportation costs.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: when multiple packaging boxes are transported together as mentioned above, the bottom wheel hubs of the above packaging boxes cannot be retracted during transportation, and thus they are difficult to stack. Multiple transportations may be required, increasing the cost of transportation. If stacking is forced, the packaging boxes on the upper layer may shake when passing through bumpy roads during transportation, causing damage to the items inside. Utility Model Content

[0017] (III) Beneficial effects

[0018] 1. By rotating the threaded rod counterclockwise, the threaded rod drives the slider to move from back to front, the slider drives the I-shaped rod to move from back to front, the I-shaped rod slides out of the torsion spring, and the packaging box is placed on top of other packaging boxes. The wheel hub slides in the sliding groove, causing the connecting rod to flip from both sides to the middle, and the connecting rod drives the rotating rod to rotate from both sides to the middle. The rotation of the rotating rod causes the torsion spring to be twisted, so that the wheel hub is stuck on the top of the top plate, and the two packaging boxes can be stacked together firmly, thereby achieving the function of easy stacking.

[0019] Second, by pressing the connecting block from right to left, the connecting block forces the second spring rod to contract, and the connecting block is retracted into the installation frame. The installation frame is pressed again, and the installation frame causes the first spring rod to contract. When the installation frame passes through the inside of the return block, the top plate can be separated from the right side plate, and the top plate can be turned counterclockwise, and then the side plates can be turned from the middle to both sides, so that the entire packaging box can be quickly unfolded, ensuring the convenience of taking large and heavy objects, greatly facilitating the unpacking of large and heavy objects, thereby achieving the function of quickly unpacking large and heavy objects.

[0026] The embodiment of the present application provides a convenient packaging box, which effectively solves the problem that when multiple packaging boxes are transported together, the bottom wheel hub of the packaging box cannot be recovered and is difficult to stack. It may need to be transported multiple times, which increases the transportation cost. If stacking is forced, the packaging box on the upper layer may shake when passing through bumpy sections during transportation, causing damage to the items inside. By rotating the threaded rod counterclockwise, the threaded rod drives the slider to move from back to front, and the slider drives the I-shaped rod to move from back to front, the I-shaped rod slides out of the torsion spring, and the packaging box is placed on top of the other packaging boxes. The wheel hub slides in the sliding groove, causing the connecting rod to flip from both sides to the middle, and the connecting rod drives the rotating rod to move from both sides to the middle. The rotation of the rotating rod causes the torsion spring to be twisted under force, so that the wheel hub is stuck on the top of the top plate, and the two packaging boxes can be stacked together firmly, thereby achieving the function of easy stacking; then, by pressing the connecting block from right to left, the connecting block causes the second spring rod to be contracted under force, and the connecting block is retracted into the installation frame; the installation frame is pressed again, and the installation frame causes the first spring rod to contract; when the installation frame passes through the return block, the top plate can be separated from the right side plate, the top plate can be turned over counterclockwise, and then the side plates can be turned over from the middle to both sides, so that the entire packaging box can be quickly unfolded, ensuring the convenience of taking out large and heavy objects, greatly facilitating the unpacking of large and heavy objects, thereby achieving the function of quick unpacking of large and heavy objects.

[0030] A rotating rod 22 is rotatably installed inside the base 21, a torsion spring 23 is sleeved on the rotating rod 22, an end of the torsion spring 23 away from the rotating rod 22 is fixedly installed with the base 21, an end of the torsion spring 23 away from the base 21 is fixedly installed with the rotating rod 22, a connecting rod 24 is fixedly installed on the side wall of the rotating rod 22, a hub 25 is rotatably installed inside the connecting rod 24, an I-shaped rod 26 is slidably installed inside the rotating rod 22, a slider 27 is fixedly installed on the side wall of the I-shaped rod 26, a threaded rod 28 is threadedly installed inside the slider 27, a knob 29 is fixedly installed on the end of the threaded rod 28 away from the base 21, and a knob 29 is fixedly installed on the end of the threaded rod 28 away from the knob 29 The end is rotatably installed with the base 21, and the threaded rod 28 is rotated counterclockwise, and the threaded rod 28 drives the slider 27 to move from back to front, and the slider 27 drives the I-shaped rod 26 to move from back to front, and the I-shaped rod 26 slides out of the torsion spring 23, and the packaging box is placed on top of other packaging boxes. The hub 25 slides in the sliding groove 31, so that the connecting rod 24 flips from both sides to the middle, and the connecting rod 24 drives the rotating rod 22 to rotate from both sides to the middle. The rotation of the rotating rod 22 causes the torsion spring 23 to be twisted by force, so that the hub 25 is stuck on the top of the top plate 13, and the two packaging boxes can be stacked together firmly, thereby achieving the function of easy stacking.

[0031] A sliding groove 31 is provided on the top of the top plate 13, and when the wheel hub 25 is clamped inside the top plate 13, it is convenient to clamp the two packaging boxes.

[0032] In view of the problems existing in the prior art, the utility model provides a convenient packaging box, by rotating the threaded rod 28 counterclockwise, the threaded rod 28 drives the slider 27 to move from the back to the front, the slider 27 drives the I-shaped rod 26 to move from the back to the front, the I-shaped rod 26 slides out of the torsion spring 23, the packaging box is placed on top of other packaging boxes, the hub 25 slides in the sliding groove 31, the connecting rod 24 flips from both sides to the middle, the connecting rod 24 drives the rotating rod 22 to rotate from both sides to the middle, the rotating rod 22 rotates to force the torsion spring 23 to twist, so that the hub 25 is stuck on the top of the top plate 13, and two packaging boxes can be stacked stably.
