Plugging structure for antenna mounting screw hole outside aircraft body

In order to solve the problems in the prior art that subsequent disassembly is difficult and glue is difficult to clean since a deep hole is blocked by glue after an antenna is mounted in the antenna mounting screw hole outside an airplane body, the embodiment of the utility model provides a plugging structure for the antenna mounting screw hole outside the airplane body, which comprises the deep hole, a deep hole end face in the deep hole is provided with a screw hole; the mounting screw is used for being in threaded connection with a machine body after penetrating through the screw hole of the antenna; the plug is used for being detachably connected with the deep hole in a sealed mode through the sealing ring so that the installation screw can be sealed and plugged in the deep hole. According to the embodiment of the utility model, the deep hole, the mounting screw and the plug are detachably and hermetically connected with the deep hole through the sealing ring, so that the mounting screw is hermetically p
