Glove operation box with wide pressure range

The invention discloses a glove operation box with a wide pressure range, which belongs to the field of material and chemical synthesis and comprises a sealing glove, a closed outer shell, a vacuum inner shell, a pressure sensor, a vacuum sensor, a vacuum pump, a protective gas cylinder, a gas valve and a fixed support column. The sealing silica gel gloves are installed on the two symmetrical side faces of the closed shell. The vacuum inner shell is installed in the closed outer shell and connected to a vacuum pump and a vacuum pressure gauge on the outer side through a feed-through pipeline, and meanwhile, a gas valve is in gas communication with the closed outer shell. The closed shell is connected with a gas cylinder, protective gas can be injected into the glove operation box through the gas cylinder, and the pressure is displayed in real time through an external pressure meter. Through the design, the vacuum inner shell used for operation has a pressure environment with a wide range from positive pressur
