Description

TECHNICAL FIELD

[0001] The utility model relates to paper box technical field, concretely to a multilayer paper box structure. BACKGROUND

[0002] As a common packaging material, paper boxes are usually used for wrapping goods and protecting articles, and are widely used in various industries. Paper boxes not only play a protective role in transportation and storage, but also enhance the aesthetic appearance and brand image in product display. The size of the paper box can be flexibly adjusted according to the specifications of the goods, and has become an indispensable part of the modern logistics industry. With the increasing requirements of logistics transportation, in order to enhance the container function and practical performance of the paper box, many large paper boxes gradually adopt a layered structure design to facilitate the rational separation of articles and improve space utilization.

[0003] The patent with publication number CN219728925U discloses a multilayer paper box structure, which includes a box body, a through slot is uniformly formed on the front side of the box body, a partition plate is inserted into the through slot, a cover plate is installed on the upper end of the box body, a fixing mechanism is installed on both sides of the box body, a T-shaped slot is formed on both sides of the inside of the box body, an insertion slot is formed on the inner wall of the side of the box body away from the through slot, a fixed block is connected to the four corner positions of the front side of the box body corresponding to the through slot, and a bolt is fixedly installed on the side of the fixed block away from the box body. The utility model is provided with a partition plate, a first clamping groove, a fixed block, a bolt and a rotating block, which are used in cooperation. When the staff needs to take out the partition plate, the rotating block is rotated to make the rotating block and the fixed block form a "I" shape, and the partition plate can be directly pulled out. The fixing mechanism is provided to facilitate the staff to install and dismount the cover plate, and the traditional method of using adhesive tape to cover the paper box is changed.

[0004] The above-mentioned prior art uses the cooperation of the partition plate, the first clamping groove, the fixed block, the bolt and the rotating block to facilitate the staff to dismount and take out the partition plate to some extent. However, in actual use, when the article placed on the bottommost partition plate needs to be taken out, the articles on the upper partition plates still need to be taken out one by one in order, and the partition plates need to be dismounted layer by layer until the bottommost partition plate is completely exposed before the required article can be obtained. This operation process is too complex, not only wasting time, but also increasing the inconvenience in use, especially in the scenario of needing to quickly take out goods. Therefore, the design of the prior art does not fully meet the actual needs, the operation efficiency is low, and there is room for improvement. In view of this, we propose a multilayer paper box structure. UTILITY MODEL CONTENTS
