[0002] Fire test equipment is a device used to evaluate the fire resistance of materials, products, or components under fire conditions. It is typically used to test a material's combustion characteristics, smoke production, toxicity release, and other indicators to determine its reaction to a fire and its impact on fire spread. Fire test equipment typically consists of a fire source, a test specimen holder, monitoring instruments, and an exhaust system. It can simulate different fire scenarios, such as small fire sources, large fire sources, or direct contact with combustible materials. Fire testing of materials allows for the evaluation and comparison of their fire resistance performance, providing a reference for fire protection design and material selection in fields such as construction, transportation, electrical, and electronics.

[0003] The fire extinguishing equipment used in some fire test devices may be disposable, meaning it becomes unusable after use during the test. This requires frequent replacement of fire extinguishing equipment during the test, increasing costs and wasting resources. The fire extinguishing agent may not be recovered or refilled, resulting in a large amount of wasted fire extinguishing agent during the test, increasing the burden on the environment. Therefore, we sought to design a fire test device with a novel structure to address this problem. Utility Model Content

A test combustion rack is movably installed on the upper side of the test bench 130 through the perforated plate. A storage cavity is provided inside the test bench 130. The setting of the perforated plate facilitates the installation of the test combustion rack and can also guide the falling fire extinguishing materials so that they can smoothly and slowly enter the storage cavity for storage.

[0029] The driving member 230 includes a heat-insulating shell and a driving motor. The driving motor is installed inside the heat-insulating shell and is connected to the upper end of the shaft 220 through a coupling.
