[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: A strengthened inner lining type foam packing box, including a foam packing box 1, an outer cover 4 is covered on the top opening of the foam packing box 1, an inner lining 2 is installed inside the foam packing box 1, and an inner cover 3 is covered on the top of the inner lining 2;

[0023] One top plate 7 is installed on each of the front and rear sides of the inner lining 2, and one side plate 6 is installed on each of the left and right sides of the inner lining 2. The inner cover 3 is located in the foam packing box 1. The bottom of the inner lining 2 is in contact with the top of the support column 5, and the bottom of the support column 5 is adhesively bonded to the inner wall of the foam packing box 1. The inner lining 2 is made of foam material, the inner cover 3 and the support column 5 are made of flexible rubber material, and the inner lining 2 is installed inside the foam packing box 1 in a suspended state through the bottom of the support column 5;

[0024] When the foam packing boxes 1 are stacked and squeezed from above and below, at this time, the inner cover 3 and the support column 5 will deform, and thus the squeezing force received can be reduced.

[0025] Preferably: A central hole 201 is opened in the inner lining 2 in the front-back direction, and three side holes 202 are opened in the inner lining 2 in the left-right direction. A central rod 701 is inserted into the central hole 201, and a reinforcement rod 601 is inserted into each of the side holes 202. Three through holes 702 are opened on the central rod 701, and each reinforcement rod 601 is respectively installed in the side hole 202 through a through hole 702 on the central rod 701.

[0026] During specific use, during installation, first insert the central rod 701 into the central hole 201. After the central rod 701 completely enters the inner part of the central hole 201, at this time, the two ends of the central rod 701 are on the same horizontal plane as the outer walls on both sides of the inner lining 2, and the three through holes 702 on the central rod 701 are respectively communicated with a side hole 202;

[0027] At this time, the reinforcing rod 601 is installed through the side hole 202 and the through hole 702 into the inner liner 2. After the above operations are completed, the inner liner 2 is installed into the foam packaging box 1. After the inner liner 2 is installed in place, the side plates 6 and the top plate 7 are installed in the gap between the inner liner 2 and the inner wall of the foam packaging box 1;

[0028] After installation, the two side plates 6 are respectively in contact with one end of the reinforcing rod 601, and the two top plates 7 are respectively in contact with the ends of a center rod 701;

[0029] When in use, the article is placed inside the placing opening on the inner liner 2, and then the inner cover 3 and the outer cover 4 are successively covered. When multiple groups of foam packaging boxes 1 are arranged and stacked in sequence, the surroundings and the top of the foam packaging box 1 will be squeezed due to factors such as jolting and extrusion during transportation. In this way, the side plates 6 and the top plate 7 will also be squeezed synchronously. At this time, the reinforcing rod 601 and the center rod 701 will bear the transmitted squeezing force, thereby protecting the inner liner 2 and the foam packaging box 1.
