Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
The plug 1 of the aviation plug has a base connection end 11 connected to the base 2 as shown in fig. 2. Correspondingly, the base 2 includes a plug connection end 21 matching with the base connection end 11, and an end opposite to the plug connection end 21 is a body connection end 22. The body connection end 22 is used to make a connection with the body interface 5 at an external structure. As shown in fig. 3, the base 2 is a cylindrical structure and is sleeved with a circular mounting plate 23, and a circular sealing gasket 4 is sleeved on one side of the mounting plate 23 facing the body connecting end 22. The shape of the sealing gasket 4 is matched with the side surface of the mounting plate 23, the sealing gasket is made of rubber or polytetrafluoroethylene, and the sealing gasket 24 can be manufactured according to the shape of the actual mounting plate 23 and the application scene. In addition, the base 2 is externally fitted with a coupling flange 4 as shown in fig. 4. The connecting flange 4 is provided with a fixing collar 31 adapted to its outer surface facing the base 2.
