Description

TECHNICAL FIELD

[0001] The present application belongs to the field of logistics packaging, and particularly relates to a folding box structure. BACKGROUND

[0002] With the continuous improvement of economic development and living standards, online shopping has become a popular shopping method for the public. Correspondingly, the express industry has also entered a stage of relatively rapid development. Most of the existing express packaging boxes are paper box structures, which are generally used only once. Therefore, a large number of discarded packaging boxes are generated, causing great waste of resources.

[0003] In order to solve this problem, some logistics companies have begun to use shared express boxes made of PVC material and set binding blocks in the express boxes to facilitate the fixation of goods. This kind of express box can be reused multiple times, reducing resource waste and avoiding damage caused by sliding and collision of goods during transportation. However, the existing express box device is not flat even after folding, which greatly increases the storage space of the express box and causes inconvenience in storage.

[0004] The existing patent with application number 202022885507.3 discloses an express box for transportation, which comprises an express box body composed of an express box outer layer and an express box inner layer. The upper end of the express box body is provided with an express box cover, and the upper end of the express box cover is provided with a fixing groove. The bottom of the express box outer layer is provided with a fixing block, and the inner surface of the express box outer layer and the outer surface of the express box inner layer are connected with shock-absorbing springs. The inside of the express box inner layer is provided with a T-shaped sliding block sliding groove, and the inside of the T-shaped sliding block sliding groove is provided with a T-shaped sliding block. The upper end of the T-shaped sliding block is provided with a fixing strap. One side of the T-shaped sliding block is provided with a first tension bolt, and the other side is provided with a second tension bolt. The express box for transportation disclosed in the invention can well fix goods and has a good shock-absorbing effect on external collisions, avoiding damage to the goods.

[0005] However, this express box device still has the shortcomings of being not flat after folding and not compact in structure, and does not realize the functions of smooth and beautiful storage and opening for convenient storage. SUMMARY

[0006] To solve the above problems, the primary purpose of the present application is to provide a folding box with a small storage space after folding, which is smooth, compact and saves space.

[0007] The secondary purpose of the present application is to provide a folding box that can effectively improve the safety performance of the box.

[0008] Another purpose of the present application is to provide a folding box that is easy to fold and open.

[0009] The present application also aims to provide a folding box with stable structure.

[0010] To achieve the above-mentioned purposes, the technical solutions of the present application are as follows:

Due to the arrangement that the first extension is higher than the second extension, the folding of the side plate assembly can be more flat due to the height difference between the two extensions, and the space formed by the height difference and the containing cavity becomes the placement space of the folded side plate assembly. When the side plate assembly is completely overlapped with the placement space after folding, the folding efficiency is maximized. The above-mentioned structure can make the volume of the folded folding box small, smooth, compact and save space.

[0018] Further, the movable connection is a hinge structure. The hinge structure is a simple and effective structure among many movable connection structures.
