Description

Technical Field

[0001] The utility model relates to the technical field of carton support auxiliary equipment, in particular to an internal support structure for preventing carton deformation. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers is also different. Even so, cartons cannot avoid a shortcoming, which is too fragile and easy to deform, resulting in deformation during logistics transportation or long-term storage, so that the internal items are damaged. For this, China Patent discloses a carton reinforcement for anti-deformation support of the carton with the authorization announcement number CN215044595U, which solves the problems existing in the use of existing cartons. It can ensure the strength of the carton when transporting items or storing items for a long time, prevent deformation and damage to the items, and adjust the size of the reinforcement according to the size of the carton. However, there are still some shortcomings. The device adjusts the size by rotating the adjustment rod 100. When one of the adjustment rods 100 is adjusted, the adjustment rod 100 adjacent to or parallel to it is prone to bending and deformation, which affects the support strength. Therefore, at least two parallel adjustment rods need to be adjusted at the same time. However, it is inconvenient to operate and cannot be adjusted quickly during simultaneous adjustment, and the efficiency is not high. Utility Model Content
