Description

Technical Field

[0001] The invention relates to the technical field of maintenance tool storage, and in particular to a portable aircraft maintenance tool storage device. Background Art

[0002] Aircraft maintenance refers to the regular or irregular maintenance, inspection and repair of aircraft to ensure the safety, reliability and air performance of the aircraft, thereby ensuring the safety of passengers and crew members. When performing maintenance operations on aircraft, various maintenance tools are required. Machine maintenance tools include small maintenance tools such as rescue hoists, wheel jacks, wheel chocks, tool boxes and brake assemblies, and large maintenance tools such as machine jacks, towing rods, mobile flatbeds and fire extinguishers. Most of the tool storage devices in the prior art can only store small maintenance tools in a centralized manner, and there is no way to store and use large maintenance tools together. As a result, when the operator is performing maintenance on the aircraft, he needs to carry large maintenance tools many times, which is very inconvenient and greatly reduces the efficiency of the maintenance operation. To this end, we specially propose a convenient aircraft maintenance tool storage device. Summary of the invention
