Nitrogen filling device for metal indium

The utility model relates to the technical field of metal indium nitrogen, and discloses a metal indium nitrogen filling device which comprises a device body, the top of the device body is fixedly connected with a filling assembly, the outside of the filling assembly is detachably connected with an assembly convenient to disassemble, and the assembly convenient to disassemble comprises a fixing frame. The sealing device has the advantages that the two second sealing blocks are placed outside the air inlet pipe, then the two first sealing blocks are placed outside the air conveying pipe and located at the tops of the two second sealing blocks, and therefore the connecting position between the air inlet pipe and the air conveying pipe is sealed through the first sealing blocks and the second sealing blocks; through the arrangement of the first sealing block and the second sealing block, the situation of gas leakage is not prone to occurring when metal indium nitrogen is poured, so that the pouring safety and po
