Embodiment 1
[0030] A paper packing box with double buffer function, such as Figure 1-4 As shown, it includes a packing box 1, a first buffer plate 2, a first spring 3, a buffer mechanism 4 and a closing mechanism 5, and a first buffer plate 2 is slidably connected between the inner walls of the front and rear sides of the lower part of the packing box 1. The buffer plate 2 can buffer the articles. The first springs 3 are installed between the four corner positions of the lower side of the first buffer plate 2 and the four corner positions of the inner bottom wall of the packing box 1. A buffer plate 2 plays the role of buffer reset, the inner wall of the packing box 1 is connected with a buffer mechanism 4, which can buffer the articles, the upper side of the packing box 1 is connected with a closing mechanism 5, and the closing mechanism 5 can be used for the packing box 1. Play a protective role.

Embodiment 2
[0035] On the basis of Example 1, as figure 1 and Figure 5 As shown, it also includes a shock absorbing mechanism 6 that can shock the packaging box 1. The shock absorbing mechanism 6 includes a third buffer plate 61, a movable block 62, a third spring 63 and a first sliding rail 64. The packaging box 1 The four outer corners of the bottom are fixedly connected with movable blocks 62, and first sliding rails 64 are slidably connected to the movable blocks 62. The first sliding rails 64 can guide the movable blocks 62, and the four first sliding rails A third buffer plate 61 is connected between the lower side of the 64, the third buffer plate 61 can buffer the packing box 1, and a third spring 63 is connected between the lower side of the movable block 62 and the upper side of the third buffer plate 61. , the third springs 63 are all wound on the surface of the first slide rail 64 , and the third springs 63 can buffer and reset the movable block 62 .
