Normally, the rotary cover 6 is located in the groove 53, the rotary cover 6 is located at the box sealing position, the box sealing device E is located at the box sealing state, and the box cover is closed on the box body B. When the box is required to be opened, the rotary cover 6 is rotated to enable the rotary cover 6 to be located at the box opening position, at the moment, the rotation angle of the rotary cover 6 is not smaller than 90 degrees, the rotary cover 6 drives the pushing block 7 to longitudinally move, and the pushing block 7 drives the first inserting buckle block 8 and the second inserting buckle block 9 to transversely move at the same time, so that the first inserting buckle 81 and the second inserting buckle 91 are respectively separated from the first buckling hole 31 and the second buckling hole 41. At the same time, the top post 72 abuts against the case cover and separates the case cover from the case body B, the first insert buckle 81 and the second insert buckle 91 are separated from and separated from the first buckle hole 31 and the second buckle hole 41, and are not buckled any more, so that the case sealing device E is in the case opening state, and the case opening process is completed.

When the case needs to be sealed, as long as the case cover is pressed down, the first eye-splice 81 is inserted into the first buckling hole 31 to be buckled and matched with the first buckling hole 31, the second eye-splice 91 is simultaneously inserted into the second buckling hole 41 to be buckled and matched with the second buckling hole 41, the case sealing device E is immediately in a case sealing state, and the packing case is sealed.

When the packing box is placed on the ground, under the dead weight effect of the packing box, the box sealing device E positioned on the box bottom cover D of the packing box can also seal the box bottom cover D with the box body B. Therefore, the packing box with the box sealing device is very suitable for unmanned automatic box sealing and meets the packing requirement of an automatic production line. When the box sealing device E is arranged on the box bottom cover D of the packing box A, the rotating cover 6 of the box sealing device E is arranged inside the box body B, and when the box bottom cover D needs to be opened, the rotating cover 6 needs to be rotated from the box body B to open the box bottom cover D.
