Similarly, the second buffer mechanism 11 increases the buffering and shock-absorbing function of the upper surface of the box body 1, thereby achieving the effect of buffering and shock-absorbing the upper and lower sides of the article.

[0023] Specifically, the cushioning airbag 4 is a circular sleeve structure, and a 3 mm gap is left between the front side walls of the cushioning airbag 4 .

[0024] In this embodiment, the buffer airbag 4 increases the buffering and shock-absorbing function of the inner walls around the box body 1, and the gap meets the scaling requirements of the inner diameter of the buffer airbag 4.

[0025] Specifically, the exhaust mechanism 5 includes an exhaust pipe 501 and a push-on exhaust valve 502 . The exhaust pipe 501 is installed on the lower surface of the cushioning airbag 4 . The lower surface of the exhaust pipe 501 is fixedly mounted with a push-on exhaust valve 502 . The push-on exhaust valve 502 is installed on the lower surface of the partition 2 .

[0026] In this embodiment, the press exhaust valve 502 is pressed, and the gas in the cushion airbag 4 flows out through the exhaust pipe 501 and is discharged by pressing the exhaust valve 502, so that the inner diameter of the cushion airbag 4 increases.

[0033] During use, according to the diameter of the fragile goods to be packaged, the bottom cover 7 is opened to allow the exhaust mechanism 5 and the inflation mechanism 6 to leak out, and the exhaust valve 502 in the exhaust mechanism 5 is pressed, and the gas in the cushioning airbag 4 flows out through the exhaust pipe 501, and is discharged by pressing the exhaust valve 502, so that the inner diameter of the cushioning airbag 4 becomes larger, or the inflatable airbag component 602 in the inflation mechanism 6 is repeatedly pressed, and the inflatable airbag component 602 allows external gas to flow into the cushioning airbag 4 through the air inlet pipe 601, so that the inner diameter of the cushioning airbag 4 becomes smaller, so that the inner diameter of the cushioning airbag 4 matches the fragile goods. After the adjustment is completed, the bottom cover 7 is threadedly installed on the lower surface of the box body 1, and the fragile goods are inserted into the cushioning airbag 4. At the same time, the lower surface of the fragile goods is placed on the upper surface of the first buffer mechanism 3, and then the top cover 8 is threadedly installed on the upper surface of the box body 1, and the circle in the adjustment mechanism 9 is adjusted.

The lower surface of the second buffer mechanism 11 is tightly fitted with the upper surface of the fragile item to achieve the effect of limiting the upper and lower positions. The shock-absorbing rubber pad 301 and the air cushion 302 in the first buffer mechanism 3 and the second buffer mechanism 11 have better buffering and shock-absorbing functions, that is, the buffering and shock-absorbing functions of the upper and lower surfaces of the box body 1 are increased, and the items are wrapped from all sides and the upper and lower sides, and the buffering and shock-absorbing functions of the packaging box are increased. It makes the items not easily bumped and damaged, so that the packaging box can meet the packaging needs of items of various specifications, better wrap the items tightly, and is highly practical.
