Description

TECHNICAL FIELD

[0001] The present application relates to the field of precision goods packaging, in particular to a square precision goods packaging carton easy to take and place. BACKGROUND

[0002] It is known that in modern society, some industrial equipment, household appliances, communication equipment, medical equipment and even aviation and navigation manufacturing industries need to use precision parts. After the production of precision parts, they often need to be transported to other places for processing, assembly or use. The transportation of precision parts needs to use special packaging protection devices to ensure that they will not be damaged during transportation.

[0003] However, some precision goods often need to be transported over long distances and moved to the work site. If not properly packaged, they are easy to be damaged due to vibration, collision, extrusion, etc. during transportation and handling. In addition, due to the installation structure, the appearance of some square precision goods is not very regular. If the traditional packaging carton is used, it is difficult to make the stress of each part of the packaged product uniform, and the overall pressure strength is not enough. Due to the local suspension or large stress, the local part is easy to be damaged during long-distance logistics transportation and handling.

[0004] To solve the above problems, when transporting and packaging the existing square precision goods, EPE pearl cotton is usually wrapped around the precision goods. Some also put fillers (such as newspapers, foam or small clothes) between the precision goods and the outer box to prevent the precision instruments from shaking in the box. Some also put cover foam blocks. This packaging method obviously not only increases the packaging cost, but also causes white pollution that cannot be degraded. In addition, some square precision goods on the market are packaged and protected by setting an inner liner in the outer box to support. However, the inner liner used is of fixed structure, which makes it inconvenient for people to take and place the square precision goods in actual application. Sometimes, the inner liner needs to be damaged to take out the square precision goods. The damaged inner liner cannot be reused for packaging if it needs to be replaced and adjusted on site, which brings inconvenience to the user.

[0005] Therefore, the present application is produced in view of the above-mentioned defects in the prior art. SUMMARY

[0006] To solve the above technical problems, we propose a square precision goods packaging carton easy to take and place.
