Description

Technical Field

[0001] This utility model relates to the field of foam box technology, specifically to an enhanced foam box structure. Background Technology

[0002] Foaming is the process of creating a microporous structure in plastics. Almost all thermosetting and thermoplastic plastics can be made into foamed plastics. In the foaming molding process or in foamed polymer materials, a honeycomb or porous structure is formed through the addition and reaction of physical or chemical foaming agents. The basic steps of foaming molding are the formation of bubble nuclei, the growth or expansion of bubble nuclei, and the stabilization of bubble nuclei. Under given temperature and pressure conditions, the solubility of gas decreases until it reaches saturation, allowing excess gas to be expelled and form bubbles, thus achieving nucleation. Foaming technology is widely used, and many boxes are filled with foaming technology, which effectively reduces structural weight and has good thermal insulation performance. However, the existing foamed box structure has low strength. If the box is stacked too high during transportation, it is easy to deform and break when subjected to external impact, thus reducing the service life of the box. Therefore, designing an enhanced foamed box is of high practicality. Utility Model Content

[0003] The purpose of this utility model is to provide an enhanced foamed box structure to solve the problems mentioned in the background art, such as the low strength of existing foamed box structures, the easy deformation of the box when stacked too high during transportation, and the easy breakage when subjected to external impact, thereby reducing the service life of the box.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an enhanced foamed box structure, comprising a box and a reinforcing structure;

[0005] The box consists of an inner liner and an outer shell. The top edge of the inner liner is connected to an L-shaped outer frame. The bottom of the connection end between the L-shaped outer frame and the inner liner is fixedly connected to the outer shell. The outer shell covers the outside of the inner liner. The end of the L-shaped outer frame away from the connection with the inner liner is covered on the top of the outer shell. The connection between the inner liner and the outer shell forms an inner cavity, which is filled with foam.

[0006] The reinforcing structure includes short grooves on both sides of the inner wall of the outer shell, a long groove in the middle of the two short grooves, the long groove extending to the bottom of the inner wall of the outer shell, reinforcing ribs formed on the outer wall of the outer shell at the short grooves and the long groove, and long grooves added at the four corners of the inner wall of the outer shell, the added long grooves forming reinforcing ribs at the four corners of the outer shell.

[0007] As a preferred embodiment of this utility model: the two diagonally connected parts of the L-shaped outer frame are provided with mounting grooves, and a pin is inserted inside the mounting grooves. The top two sides of the box are provided with split cover plates, and a connecting block is connected to the bottom of one side of the cover plate.
