[0033] A pair of buffer mounting plates 101 are respectively arranged at both sides of the mounting cavity 100, a plurality of partition plates 102 are arranged between the pair of buffer mounting plates 101, and connecting plates 103 are respectively arranged at both ends of the partition plates 102, and the connecting plates 103 at both ends of the partition plates 102 are respectively connected to the pair of buffer mounting plates 101 through detachable bolts 104;

[0034] A pair of buffer mounting plates 101 are each provided with a plurality of rows of first threaded connection holes 105, and a plurality of second threaded connection holes 106 that are matched with the first threaded connection holes 105 are provided on the connecting plate 103. The detachable bolts 104 pass through the first threaded connection holes 105 and the second threaded connection holes 106, and are threadedly connected with the first threaded connection holes 105 and the second threaded connection holes 106.

[0035] like Figure 3 to Figure 4 As shown, when the utility model is in use, the second threaded connection holes 106 on the connecting plates 103 at both ends of the dividing plate can be matched with the first threaded connection holes 105 on a pair of buffer mounting plates 101, so that the dividing plate can be installed at different positions on the buffer mounting plate 101, so that the space between the pair of buffer mounting plates 101 can be divided into spaces of different sizes by the dividing plate 102, which is conducive to the protection of different goods. The connecting plate 103 is connected to the buffer mounting plate 101 with a detachable bolt 104, which can facilitate the disassembly of the dividing plate 102 and the adjustment of the position of the dividing plate. The provision of a plurality of dividing plates 102 can realize the division of the space between a pair of buffer mounting plates 101 into multiple spaces, which is convenient for adapting to the size of the goods. It solves the problem that the internal space of the current cargo protection device for logistics cannot be adjusted when in use, and cannot be applied to the transportation of a variety of goods.

[0036] Due to the instability of the logistics transportation process, the logistics transportation process may encounter bumps caused by various situations. In order to provide a certain buffering and protective effect on the goods during the bumps, this embodiment is modified on the basis of the above embodiment. The difference from the above embodiment is that the buffer mounting plate 101 is slidably arranged on both sides of the protection box body 10, and a pair of plug-in parts 107 are provided on one side of the buffer mounting plate 101.

At the same time, it also solves the problem of the protective box body 10 tipping over or tilting due to the collision of the goods with the inner wall of the protective box body 10. Since the buffer airbag 111 has a certain elasticity, when it is not subjected to external force, the buffer airbag 111 is reset and then drives the buffer mounting plate 101 to reset.
