Description

Technical Field

[0001] The utility model belongs to the technical field of compression-resistant composite paper pallets, and in particular relates to a compression-resistant composite paper pallet. Background Art

[0002] Compression-resistant composite paper pallet is a kind of pallet for logistics transportation made of paper material. It is mainly made of multiple layers of paper through lamination and pressing processes. It has the advantages of strong load-bearing capacity, environmental protection, recyclability and low cost.

[0003] The design of the compression-resistant composite paper pallet enables it to bear a certain weight of goods and has good stability and durability during use. Its structure usually includes a panel and a support foot. The panel is used to carry the goods, while the support foot is used to support the structure of the entire paper pallet.

[0004] For example, a Chinese patent with publication number CN217416471 U discloses a compression-resistant composite paper pallet, including paperboard, the bottom of which is fixedly connected with a support block, the number of which is nine, and the nine support blocks are evenly distributed at equal intervals, the bottom of the support block is provided with a connecting plate, the number of which is three, and the three connecting plates are evenly distributed at equal intervals, the top of the connecting plate is fixedly connected to the bottom of the support block, the top of the paperboard is fixedly connected with a reinforcing plate, the surfaces of the reinforcing plate and the paperboard are fixedly connected with a covering plate, the top of the covering plate is fixedly connected with a grid plate, and the top of the grid plate is fixedly connected with a top plate. The utility model is used in conjunction with paperboard, support blocks, connecting plates, reinforcing plates, covering plates, grid plates and top plates, so as to have the advantage of good compression resistance, and solve the problem that the traditional paper pallet has a relatively simple structure, poor compression resistance, and is prone to deformation when carrying objects with excessive weight, which easily leads to poor bearing effect.

[0005] The above patent has the following problems:

[0006] This patent has some disadvantages when in use, such as: when the above-mentioned compression-resistant composite paper pallet is placed on the ground for use, because its supporting feet are also made of compression-resistant composite paper, when the supporting feet of the compression-resistant composite paper pallet encounters a wet ground, the supporting feet of the compression-resistant composite paper pallet will absorb moisture on the ground, causing its fiber structure to expand and deform, causing the strength of the supporting feet to drop significantly, and it may no longer be able to effectively support heavy objects. In view of this, we propose a compression-resistant composite paper pallet. Utility Model Content

By setting the first slide groove and the first slider, it is ensured that the first slider can slide in the first slide groove. By setting the limiting component, when the first slider slides to a suitable position along the first slide groove to the outside world, the first slider will be affected by the limiting component and be fixed to the outside world and cannot move.

[0023] In the above technical solution, further, one end of the rotating rod is fixedly connected to an anti-sliding block.

[0024] In this technical solution, it is ensured that when one end of the rotating rod contacts the ground, the friction between the entire device and the ground can be increased to prevent the entire device from sliding.

[0025] In the above technical solution, further, the other end of the sliding rod is in a rectangular structure.

[0030] The compression-resistant composite paper pallet ensures that the reinforcement plate can be fixed in the installation groove by the provided installation groove and the reinforcement plate, and plays a reinforcing role on the supporting foot. The provided first slide groove and the first slider ensure that the first slider can slide in the first slide groove. Through the provided limit assembly, when the first slider slides to a suitable position toward the outside along the first slide groove, the first slider will be affected by the limit assembly and be fixed to the outside and cannot move. Through the provided second slide groove and the second slider, the second slider can be ensured to slide in the second slide groove. Through the provided extrusion block, the fourth slide groove and the slide rod, the slide rod can be ensured to drive the extrusion block to move in the second slide groove along the fourth slide groove. Through the provided driving assembly, the user can drive multiple slide rods to move through the driving assembly, which solves the problem that when the supporting foot of the compression-resistant composite paper pallet encounters a wet ground, the supporting foot of the compression-resistant composite paper pallet will absorb moisture on the ground, causing its fiber structure to swell and deform, which significantly reduces the strength of the supporting foot and may no longer be able to effectively support heavy objects.
