Box-instrument integration multi-level cushion packaging storage and transportation box

Abstract

The invention relates to a box-instrument integration multi-level cushion packaging storage and transportation box, which comprises an outer box and an internal cushioning mechanism and is characterized in that the outer box consists of two box covers, a box body and a base, wherein the box covers are connected with the box body by hinges and are fixed with the box body by lock catches, a rubber absorber is arranged between the bottom of the box body and the base, the bottom of the box body and the base are respectively connected with the two ends of the rubber absorber through bolts, and the packaging storage and transportation box is composed of the base, the rubber absorber, the box body, eight spherical steel wire rope springs and a hydraulic damper and is in a form of five-level cushion. The packaging storage and transportation box has the beneficial effects that the packaging storage and transportation box provides the five-level cushion protection, an enough cushion space can be supplied for a precise instrument under the air-drop environment so that the bottom-collision damage is avoided, and the packaging storage and transportation box can realize effective cushion protection for the precise instrument with a brittle value less than 15G. The box covers, the box body and the base form an operation platform, the instrument is arranged on an instrument fixing frame, and the instrument is not necessarily taken out for work, and therefore the box-instrument integration is realized.

Description

technical field [0001] The invention belongs to a storage and transportation box, in particular to a multi-level buffer packaging storage and transportation box which is mainly used for buffering and protecting precision instruments in an airdrop environment. Background technique [0002] At present, during emergency rescue in war or non-war military operations (such as earthquakes, floods, etc.), airdrops are often used to transport materials to their destinations. The instrument equipment adopts the comprehensive buffer method of thickened cushioning liner, and a thick cushioning liner is filled between the instrument equipment and the outer box to form a pattern of large outer box and small instrument. At the moment when the airdrop hits the ground, due to the large impact force, it exceeds the damage boundary of the instrument and equipment. For some brittle values, it is 30G (G is the brittle value, which is the maximum acceleration that a specific product can withstand...

AI Technical Summary

Problems solved by technology

Since the above two structures adopt a single-stage vibration isolation method, the space for buffer vibration isolation is limited. In the simulated airdrop test (free fall from a height of 2.5m, landing speed of 7m / s), the instrument with a brittleness value less than 25G cannot be used. adequate protection
