[Abstract]Objective： Developing one systematized, rapidly-varied, and general type of stretcher test fixture. Methods： Basing on the existing situation of the stretcher testing, series of stretcher standards and common testing methods are learned, as the main design idea. Results： The design scheme of universal stretcher test fixture is formed. Conclusion： The design balances a variety of test project requirements, and it meets the test requirements well.

Handling tools transporting the wounded is wounded war injuries can receive timely treatment are the key. Currently, there are all kinds of transportation tools casualty stretchers, harnesses, skateboards and puller, etc., which is the main stretcher handling tools. Stretcher with a rescue wounded convenient, fast and efficient features. Today stretcher diverse species, its rapid development, huge usage. However, in case of problems often occur stretcher wounded in order to ensure the success rate of wounded must do quality control stretcher.

1 stretcher and detect the status quo

Domestic common types are common stretcher stretcher, folding stretcher, vacuum stretcher, floating stretcher and shovel stretcher. Universal stretcher structure includes stretcher surface, stretcher bars, legs, steel crossbars, the wounded and the strap handles and other parts. The survey found that there is no uniform national testing standards stretcher, stretcher existing test items not sound detection instruments stretcher no uniform standards, mostly based on existing conditions to perform simple checks, can not achieve scientific The system of testing. Therefore, the design one for most of the stretcher and set a variety of common test items in one test-bed stretcher, the stretcher is the development and use of urgent needs.

2 stretcher generic detection project and technical indicators

Universal stretcher testing station design, focusing on a stretcher universal test project. By combing stretcher standards, summed up the basic size stretcher, carrying capacity, handle disengagement force and the opening force strut core test items.
