The positioning posts 512, together with the first and second buckles 81 and 91, effectively enhance the drop resistance of the package A, preventing accidental opening after a fall. Therefore, the box sealing device E of the present invention also enhances the drop resistance of the package A.

[0036] A compression spring 14 is provided between the push block 7 and the buckle seat 5. Under the action of the compression spring 14, the push block 7 automatically returns to the initial box sealing position after being in the box opening position.

[0037] A limiting groove 62 and an avoidance step 63 are provided on the rotating cover 6. Figure 9 When the rotating cover 6 is in the unpacking position, the stopper groove 62 engages the wall of the groove 53, ensuring that the rotating cover 6 can rotate at least 90°. When the rotating cover 6 is in the sealing position, the clearance step 63 allows the rotating cover 6 to clear the sidewalls of the groove 53, allowing the rotating cover 6 to return to its initial sealing position. Furthermore, the provision of the clearance step 63 allows the rotating cover 6 to overlap the outer wall of the groove 53, preventing foreign matter from entering the gap between the rotating cover 6 and the groove 53 and obstructing the rotation of the rotating cover 6, thereby affecting the unpacking operation of the sealing device E.

[0038] A push post 72 for pushing open the box cover is also provided at the end of the push block 7. When the rotatable cover 6 is rotated to the box opening position, the push block 7 is also moved to the box opening position. The push post 72 extends from the buckle seat 5 and presses against the box cover, separating the box cover from the box body B. The first buckle 81 and the second buckle 91 are separated and disengaged from the first buckle hole 31 and the second buckle hole 41, respectively, and are no longer fastened. The box sealing device E is in the box opening state.

[0039] Under normal circumstances, the rotating cover 6 is located within the groove 53, in the sealing position, and the sealing device E is in the sealing state, closing the box lid on the box body B. When the box needs to be opened, the rotating cover 6 is rotated so that it is in the opening position. At this time, the rotating cover 6 is rotated through an angle of not less than 90°. The rotating cover 6 drives the push block 7 to move longitudinally, and the push block 7 drives the first and second buckle blocks 8 and 9 to move horizontally simultaneously, causing the first and second buckle blocks 81 and 91 to separate from the first and second buckle holes 31 and 41, respectively. At the same time, the top post 72 abuts against the box lid and separates it from the box body B. The first and second buckle blocks 81 and 91 are separated and disengaged from the first and second buckle holes 31 and 41, respectively, and are no longer engaged. The sealing device E is in the opening state, completing the unpacking process.

[0040] When the box needs to be sealed, just press the box cover so that the first buckle 81 is inserted into the first buckle hole 31 and snaps into engagement with the first buckle hole 31, and the second buckle 91 is simultaneously inserted into the second buckle hole 41 and snaps into engagement with the second buckle hole 41. The box sealing device E is immediately in the box sealing state, and the packaging box is sealed.

[0041] When the packaging box is placed on the ground, the sealing device E located on the bottom cover D of the packaging box can also seal the bottom cover D with the box body B under the action of the packaging box's own weight. Therefore, the packaging box equipped with the sealing device of the present invention is very suitable for unmanned automatic sealing and meets the packaging requirements of automated production lines. When the sealing device E of the present invention is installed on the bottom cover D of the packaging box A, the rotating cover 6 of the sealing device E is located inside the box body B. When the bottom cover D needs to be opened, the rotating cover 6 must be rotated from inside the box body B to open the bottom cover D. When the sealing device E of the present invention is installed on the top cover C of the packaging box A, the rotating cover 6 of the sealing device E is located outside the box body B. The top cover C of the packaging box A can be opened by rotating the rotating cover 6 downward to the opening position.

[0042] The packaging box sealing device of the present invention also allows the packaging box to be folded like a cardboard box, and after folding, it takes up minimal space and does not rebound. Figure 3 shown.
