Technical Field

[0001] The utility model relates to the field of special gas cabinets, in particular to a special gas cabinet with a gas leakage detection function. Background Art

[0002] A special gas cabinet is a device designed for the supply of flammable, explosive, corrosive, toxic and other dangerous gases. A special gas cabinet is a device used to supply special gases and is widely used in industries such as semiconductors, electronics, liquid crystals, photovoltaics and solar cells.

[0003] Existing special gas cabinets with gas leakage detection function mostly use fixed holding rings to fix the gas tanks when installing them inside the gas cabinet. This method has poor adaptability to gas tanks of different sizes and shapes. When gas tanks of different specifications need to be replaced, the entire fixing device may need to be replaced, which increases the difficulty and cost of operation. Moreover, this fixing method generally requires further fixing by tightening bolts or by binding straps. This operation method is not only inefficient, but may also cause loose fixing or damage to the gas tank due to human factors such as improper operation or negligence. Therefore, when designing a special gas cabinet with a gas leakage detection function, it is necessary to provide a novel stabilizing mechanism, which can adapt the gas tank at any time when fixing the gas tank, and can more stably fix the gas tank, thereby improving the overall practicality. Utility Model Content
