Description

TECHNICAL FIELD

[0001] The utility model relates to electronic product packaging technical field, especially inner to structure, desktop computer with full paper packing box of paperboard structure for desktop computer. BACKGROUND

[0002] For most electronic products, the buffering safety in the transportation process becomes one of the insurmountable difficulties in the product development process, and balancing between the packaging cost and the buffering safety is the biggest problem faced by the current product packaging. The existing packaging box generally comprises an outer box part and a buffering part inside it; the buffering part inside is mostly a tray structure provided with a profiling cavity; and for products with large volume or many components, the packaging method is mostly to disassemble the product components, that is, to disassemble some components convenient for installation and to package separately, mostly 2-piece or 3-piece, so as to reduce the risk in the transportation process. For example, in the transportation and storage process of a desktop computer, the display screen and the host are usually packaged separately, that is, the desktop computer components are disassembled into 2-piece; although the buffering safety of such transportation is high and can provide good protection for the product components, it increases the packaging cost and the transportation cost. If the product with many components is placed in the same packaging box, in order to prevent the collision between the components, one or more inner supports need to be used reasonably, and the inner support needs to play the role of buffering protection and limiting for the components supported thereby.

[0003] At present, the inner support is mostly made or combined of EVA, plastic or a paper card structure with complex molding; for example, in the transportation and storage process of a desktop computer, the traditional packaging method usually uses foam, plastic and other materials as the inner support of the outer box, which can effectively protect the product, but has certain disadvantages in environmental protection and resource utilization; secondly, these tray structures cannot be completely flattened, resulting in a large occupied space and further increasing the transportation cost; in addition, the paper card structure with complex molding needs to use a large amount of human resources in the production process, and the labor cost is relatively high, thereby further increasing the packaging cost of the product. However, the corrugated paper with simple molding has good effects of shockproof, impactproof and anti-static, and is pollution-free to the environment, so it is more conducive to the export of the products of the manufacturer and is widely used in the packaging of electronic products, electrical appliances, computers, mechanical parts, industrial instruments and the like. However, the simple corrugated paper has limited carrying capacity, and for electronic products such as desktop computers with many components and heavy weight, if all the components are packaged in the same packaging box, the structure of the inner support needs to be reasonably designed to meet the carrying demand. Therefore, it is urgent to develop a corrugated inner support for a desktop computer and a full-paper packaging box.
