Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a battery-powered portable explosion-proof gas detection terminal. Background Art

[0002] A gas detector, also known as a gas detector, is an instrument tool for detecting gas leakage concentration, including portable and handheld gas detectors.

[0003] Most of the existing portable gas detectors have their detector bodies connected to a fixed structure. By fixing the fixed structure to the user's belt or chest in advance, the gas detector is naturally fixed to the corresponding position. However, during use, when disassembling the detector, the corresponding fixed structure needs to be removed together. After using the detector, the fixed structure needs to be worn on the user again, which is quite troublesome. At the same time, the user is in motion when carrying the detector. The existing detector body has poor shock resistance, and the detector is easily damaged during exercise. Utility Model Content
