AI Technical Summary

Technical Problem

Existing plastic packaging boxes cannot effectively resist collisions, drops, or compression during transportation, resulting in the breakage of fragile items, misalignment of precision instrument parts, damage to items caused by shaking and friction under vibration, and their compressive strength depends on the wall thickness. They are also prone to denting and cracking when stacked or squeezed by heavy objects, thus shortening their service life.

Method used

The plastic packaging box features a protective frame, reinforcing columns, and a multi-layered structure. The protective frame absorbs impact through locking blocks and return springs, while the reinforcing columns disperse external forces through reinforcing blocks and guide grooves. The multi-layered structure provides cushioning performance, and anti-slip pads and adjustable partitions enhance compressive strength and stability.

Benefits of technology

It effectively reduces the damage rate of goods during transportation, enhances the pressure resistance of the box, prevents the deformation of goods, and extends the service life.

Abstract

This utility model discloses a plastic packaging box with a protective structure, relating to the technical field of plastic packaging boxes. It includes a box body, a lid movably connected to the top of the box body, corner guards fixedly connected to the chamfered corners of the box body, protective frames installed between the corner guards, protective rods symmetrically fixed at equal intervals inside the protective frames, fixing components installed inside the corner guards, partitions movably connected inside the box body, and handle grooves on both sides of the box body. Anti-slip mats are glued inside the handle grooves, with anti-slip textures on the surface of the mats, and the mats are made of soft rubber. This utility model, employing the above structure, can effectively absorb impact and vibration during transportation, reducing problems such as breakage of fragile items and loosening of precision instrument parts, significantly reducing the damage rate of goods, and enhancing the box's pressure resistance, preventing deformation of goods due to stacking and compression.
