Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cardboard box technology, and in particular relates to a high-strength pressure-resistant cardboard box made of composite materials. Background Technology
[0002] Cardboard boxes, as the most common packaging containers, are widely used in logistics, warehousing, and product transportation. However, traditional corrugated cardboard boxes have significant limitations in terms of load-bearing capacity, compressive strength, and impact resistance. When used to package heavy products, precision instruments, or fragile items, ordinary cardboard boxes are prone to deformation, bulging, or even collapse when stacked or subjected to external pressure, leading to damage to the contents.
[0003] Therefore, there is an urgent need in this field for a packaging carton that possesses both high strength and pressure resistance, as well as flexible and stable internal space division. Utility Model Content
[0004] In view of the above-mentioned deficiencies of the prior art, this utility model proposes a high-strength, pressure-resistant cardboard box made of composite materials. The technical solution of this utility model includes: Bottom wall 1, side walls 2, and top sealing part 3; At least one surface of the side wall 2 is laminated with a mesh reinforcing liner 4, which is an industrial mesh fabric; The inner side of the side wall 2 is provided with a detachable three-dimensional support frame system, which includes at least one set of horizontal support units and vertical limiting units.
[0005] Preferably, the transverse support unit includes a first support rail 5 and a second support rail 6 arranged opposite to each other.
[0006] Preferably, a partition plate assembly 7 is slidably installed on the first bearing guide rail 5 and the second bearing guide rail 6. The partition plate assembly 7 includes a main partition plate 8 and an auxiliary support plate 9. The two sides of the main partition plate 8 are connected to the auxiliary support plate 9 through adjusting screws 10. The end of the adjusting screws 10 is provided with a locking component 11.
[0007] Preferably, the vertical limiting unit includes corner columns 12 and central reinforcing ribs 13, and the corner columns 12 and central reinforcing ribs 13 form a stable spatial truss structure through connecting fasteners.
[0008] Preferably, the corner column 12 has a buffer cavity inside, and the buffer cavity is filled with elastic buffer material.
[0009] Preferably, a support base 14 is detachably connected to the bottom wall 1, and a positioning flange 15 is provided around the support base 14, which forms an insertion fit with the bottom of the side wall 2.
[0010] Preferably, the mesh reinforcement liner 4 adopts a dense weave structure at the edges of the box and a sparse weave structure at the plane of the box, forming a gradient reinforcement distribution.
[0011] The beneficial effects of this utility model are: 1. By using industrial-grade mesh fabric as a reinforcing lining on the side wall surface, the overall tear resistance and burst resistance of the enclosure are greatly improved. In particular, the mesh reinforcing lining adopts a dense weave structure at the edges of the enclosure and a sparse weave structure in the plane, forming a scientific gradient reinforcement distribution. This provides stronger protection at key stress points while achieving optimized material configuration. 2. The detachable three-dimensional support frame system inside the box, through the cooperation of horizontal support units and vertical limiting units, forms a stable spatial truss structure that effectively resists pressure from all directions. The partition components can slide and expand via adjusting screws, flexibly adapting to contents of different sizes and shapes, achieving personalized partition protection, making the box multi-functional, and reducing the need for specialized packaging. 3. All components, such as the load-bearing base, partitions, and corner columns, are detachable. Damaged parts (such as a partition or column) can be replaced individually without discarding the entire carton, significantly reducing maintenance and operating costs and extending the overall product lifespan.
