The invention relates to a spontaneous ignition point test device in a high-pressure oxygen-rich environment. The spontaneous ignition point test device comprises an explosive vessel, a heating system, a vessel mounting and sealing protection device module, a pressure release device module, a high-pressure oxygen supply system and a pressure and temperature signal measuring and displaying module, wherein the heating system is arranged in the explosive vessel; the explosive vessel is arranged in the vessel mounting and sealing protection device module; the pressure release device module and the high-pressure oxygen supply system are respectively connected with the explosive vessel through the vessel mounting and sealing protection device module; and the pressure and temperature signal measuring and displaying module is connected with the explosive vessel. Compared with the prior art, the spontaneous ignition point test device disclosed by the invention can be used for measuring in real time, recording pressure and temperature information in the device and analyzing a spontaneous ignition point of a material to be tested under different oxygen-rich concentrations and pressures, and has the advantages of simple structure, convenience in mounting, high test efficiency, comprehensive data and the like.

The invention discloses a clothing test assist device which comprises a machine body, a handle is fixedly arranged on the right side face of the machine body, an operation cavity penetrating front and back is formed in the handle, a first hydraulic cavity is formed in the machine body, hydraulic oil is arranged in the first hydraulic cavity, and a first piston is connected in the first hydraulic cavity in a left-right sliding mode. The right side surface of the hydraulic cavity I is internally provided with a through hole I which rightwards penetrates into the operation cavity. The device is small and exquisite in shape and convenient to carry, so that the device is suitable for real-time assault inspection, and the detection result tends to be real. The toughness and the stretching limit of the clothes can be detected, the quality of the clothes can be more visually determined through the detection item, the ignition point of the clothes can be measured, and the purity of materials used by the clothes can be preliminarily determined through the detection item; during ignition point detection, only a small piece of cloth separated from the whole clothing is ignited, and fire safety is guaranteed.
