Description

Technical Field

[0001] This utility model relates to the field of aircraft parts packaging technology, and in particular to a high-pressure-resistant packaging box based on aircraft parts. Background Technology

[0002] For high-pressure-resistant packaging used in the transportation of aircraft parts, its core function is to resist the stacking pressure, vibration and impact and environmental erosion during transportation through rigid support and cushioning protection, so as to ensure the precision of the parts. It generally includes an outer frame, a cushioning liner and a protective layer.

[0003] A search revealed Chinese patent application number 201720104014.7, which discloses a transportation device for aircraft production. The device includes a transport box with a storage mechanism fixedly installed inside. This storage mechanism includes springs, a support plate, connecting telescopic rods, shock absorbers, airbags, automatic valves, air pumps, sliders, and chutes. This invention utilizes a system where several springs are positioned at the bottom of the transport box, a support plate at the top of the springs, connecting telescopic rods at the bottom of the support plate, shock absorbers at the bottom of the support plate, an airbag at the top of the transport box, an automatic valve at the top of the airbag, an air pump at the top of the automatic valve, sliders at both ends of the support plate, and chutes at both ends of the transport box. The sliders move within the chutes, allowing aircraft parts to be placed inside the transport box. The springs and shock absorbers provide shock absorption, preventing damage to the aircraft parts during turbulence. However, due to the irregular shape of the parts, they may be damaged during transportation. Although the aforementioned patent can fix the parts by filling the inside of the transport box with the airbag at the top, the airbag requires a large pressure to keep the parts fixed when it inflates. Since the parts themselves have different shapes, such as turbine blades, hydraulic components, and sensors, a single airbag is difficult to adapt to different parts when fixing them. It is easy to damage the parts when over-pressured and cause unstable fixing when under-pressured, which affects the safety of the parts during transportation.

[0004] Therefore, there is an urgent need to solve the above problems by using high-pressure-resistant packaging boxes based on aircraft parts. Utility Model Content
