Description

Technical Field

[0001] The utility model relates to the field of anti-deformation of corrugated paperboards, in particular to an anti-deformation structure of corrugated paperboards. Background Art

[0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and a layer of boxboard paper. It has good elasticity and extensibility and is mainly used to make cartons, carton sandwiches and other packaging materials for fragile goods. The corrugated corrugations of the corrugated cardboard are like connected arched doors, arranged in a row and supporting each other to form a triangular structure. It has good mechanical strength and can withstand a certain amount of pressure from a plane. It is elastic and has a good cushioning effect. It can be made into pads or containers of various shapes and sizes as needed. It is simpler and faster than plastic cushioning materials. It is less affected by temperature, has good light-shielding properties, does not deteriorate under light, and is generally less affected by humidity. However, it is not suitable for long-term use in an environment with high humidity, which will affect its strength.

[0003] After corrugated cardboard is made into cartons, it is easy to deform due to external forces. Therefore, when packaging the materials, it cannot provide good protection for the materials. At the same time, it is inconvenient to adjust the internal loading space, which affects the scope of use.

[0004] Therefore, it is necessary to propose a corrugated cardboard anti-deformation structure to solve the above problems. Utility Model Content

It is said that a movable groove 6 is opened, and limiting grooves 7 are symmetrically opened on the front and back sides of the inner cavity of the movable groove 6. Springs 9 are symmetrically fixedly connected to the center of the opposite sides of the front and back adjustment components 10. Fitting blocks 11 are symmetrically fixedly connected to the center of the opposite sides of the front and back adjustment components 10. The front and back fitting blocks 11 are symmetrically rotatably connected to the opposite sides of the front and back fitting blocks 11. The adjusting component 10 is movably connected in the inner cavity of the movable groove 6, the fitting block 11 is movably connected in the inner cavity of the limiting groove 7, and the roller 12 is fitted on the inner wall of the limiting groove 7. Movable grooves are symmetrically opened in the center of the left and right sides of the partition 15, and limiting rods 14 are fixedly connected to the inner cavity of the movable groove. Movable blocks 13 are symmetrically fixedly connected to the center of the opposite sides of the left and right adjustment components 10. The movable blocks 13 are movably connected to the inner cavity of the movable groove and are sleeved on the outer wall of the limiting rod 14.

[0025] The inner corrugated cardboard 2 can support the outer corrugated cardboard 1. The first and second corrugated columns 3 and 4 can support the inner corrugated cardboard 2, preventing overall deformation during use.

When in use, the position of the partition 15 is adjusted according to the loading requirements, and the partition 15 is moved up and down, so that the adjustment component 10 can move in the inner cavity of the movable groove 6. The adjustment component 10 will simultaneously drive the fitting block 11 and the roller 12 to move in the inner cavity of the limiting groove 7. After the partition 15 stops moving, the spring 9 will bounce the front and back adjustment components 10 to the opposite sides, so that the fitting block 11 can drive the roller 12 to fit tightly in the inner cavity of the limiting groove 7, thereby completing the positioning of the partition 15.
