Shock absorption packaging box

Abstract

The invention discloses a shock absorption packaging box. The shock absorption packaging box comprises box bodies and a box cover. The box bodies include the inner box body and the outer box body. The lateral walls of the inner box body and the lateral walls of the outer box body are separated, and at least one lateral wall of the inner box body is an elastic plate capable of deforming in an arc shape and expanding outwards. The shock absorption packaging box further comprises an outward pulling part used for outwards pulling the elastic plate to deform the elastic plate. The shock absorption packaging box comprises an air spring which is arranged between the bottom wall of the inner box body and the bottom wall of the outer box body and used for shock absorption. The elastic plate needs to restore due to the elasticity, thereby forming certain squeezing force toward the inside of the box body to filled objects. The gaps among the objects are adjusted through the squeezing force, the objects are prevented from moving relatively, a whole is roughly formed, and therefore a stable placement effect is achieved, and collision and damage to the objects caused by relative movement of the objects are avoided. In addition, the air spring is arranged, so that longitudinally upward shock on the inner box body is absorbed. The shock absorption effect is good, and the objects are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a shockproof packaging box. Background technique [0002] Packaging boxes are generally used for the circulation of goods to facilitate the turnover of goods, and play a vital role in our lives. The packaging box has a certain storage space, and is often used to pack a variety of fragile or inconvenient foods or objects that are not easy to collide. When the items in the packaging box are filled, they can only rely on the squeeze between the items in the box to form stability. When the gap is relatively loose, shaking will occur, and in severe cases, it will cause damage to the item. The existing common method is to add anti-vibration filler. Although the process is not complicated, it is time-consuming and labor-intensive, which is not conducive to cost saving. [0003] Therefore, it is necessary to improve the existing packaging boxes so that there is a relatively stable squeezing for...
