Description

Square precision article packaging carton easy to take and place

Technical Field

The utility model relates to the field of precise article packaging, in particular to a square precise article packaging carton which is easy to take and place.

Background

As is well known, in some industrial equipment, household appliances, communication equipment, medical equipment, even aviation and navigation industries in modern society, many of the industrial equipment, household appliances, communication equipment, medical equipment, even aviation and navigation industries need to use precise parts, after the precise parts are produced, the precise parts are often transported to other places for processing, assembling or using, and special packaging protection devices are needed for transporting the precise parts so as to ensure that the precise parts cannot be damaged in the transportation process.

However, some precise articles often need to be transported and carried to a working site in a long distance, and if the packages are improper, the precise articles are easy to damage due to vibration, collision, extrusion and the like in the process of transportation and carrying. In addition, some square precise articles are not regular in appearance due to the requirement of the mounting structure, and are packaged in a manner of lining, foam or a backing plate in a traditional packaging paper box, so that the stress on all parts of the periphery of a packaged product is difficult to be uniform, the whole bearing strength is insufficient, and the parts are easy to be damaged during long-distance logistics transportation and folding due to the fact that the parts are suspended or stressed greatly.

In order to solve the above problems, when the conventional square precise articles are transported and packaged, EPE pearl wool is generally wrapped around the precise articles, and fillers (such as newspaper, foam or small clothes) are also put between the precise articles and an outer box, so that the precise instruments cannot shake in the box, and cover plate foam blocks are put in the box again. The packaging mode obviously increases the packaging cost, is easy to cause undegradable white pollution, and is deviated from the concept of energy conservation and environmental protection advocated by the state. In addition, the packing protection of the square precision articles in the market is that the inner liners are arranged in the outer boxes to support, but the adopted inner liners are of fixed structures, so that people can take out the square precision articles in actual application conveniently, sometimes even the inner liners are damaged, and the damaged inner liners cannot be repeatedly packed for use when the square precision articles meet the requirement of the scene for adjustment and replacement, thereby bringing inconvenience to users.

In view of the above, the present inventors have made intensive studies to solve the above-mentioned drawbacks of the prior art.
