Integrated fire extinguishing group device

An embodiment of the utility model provides an integrated fire extinguishing group device, which relates to the field of oil discharge and nitrogen injection fire extinguishing, and comprises a transformer and an expansion tank arranged on one side of the upper end of the transformer, a fire-fighting cabinet is arranged on one side of the lower end of the transformer, and an operator can pull a handle to drive a cushion block to slide out of an inner cavity of an embedded groove when installing a nitrogen cylinder. An operator places a nitrogen cylinder at the upper end of the hollow round block and pushes a handle again to slide the cushion block into an inner cavity of an embedded groove, so that clamping mechanisms fixedly mounted at the upper end and the lower end of one side of the inner wall of a concave block are used for limiting and clamping the periphery of the outer wall of the nitrogen cylinder; through the arrangement, the mounting stability of the nitrogen cylinder is improved, an operator does
