Embodiment Construction
[0013] Referring to the accompanying drawings, an anti-corrosion sealing method for the interior of a flap of the present application includes an outer skin 1, an inner skin 2, a blind rivet 3, a sealant 4, a quick release lock 5, a rotating bracket 6, a reinforcing profile 7, a common Rivet 8.
[0014] In implementation, the inner skin 2 is provided with an annular reinforcing socket 10 , and the outer skin 1 and the inner skin 2 are fixedly connected to the mouth cover body of an integrated structure by means of rivets 8 on the outside of the annular reinforcing socket 10 . In order to seal the inner cavity of the reinforced socket to prevent rainwater from pouring into the corrosion mouth cover structure, the application is provided with a glue filling hole 9 on the top of the reinforcement socket 10 of the inner skin 2; liquid sealant is injected into the reinforcement socket 10 through the glue filling hole 9; After injecting the liquid sealant, turn the body of the mouth...

An anti-corrosion sealing method for an inner cavity of a mouth cover. The mouth cover contains an outer skin and an inner skin, the inner skin is provided with an annular reinforcing socket, and the outer skin and the inner skin pass through rivets on the outside of the annular reinforcing socket. The cover body is fixed and connected as an integral structure, and a glue filling hole is opened at the top of the inner skin reinforcement socket; liquid sealant is injected into the reinforcement socket through the glue filling hole; the posture of the mouth cover body is rotated to make the liquid sealant flow to the outside A sealant layer is formed in the interlayer cavity of the skin and the inner skin; after the liquid sealant is cured in the interlayer cavity of the outer skin and the inner skin to form a sealant layer, the glue filling hole can be closed.
Description
technical field [0001] The present application relates to an aircraft anti-corrosion design, in particular to a method for anti-corrosion sealing of a cavity inside a flap. Background technique [0002] The cover used on the aircraft is generally composed of inner skin, outer skin, reinforcing profiles, rotating brackets, and quick-release locks. The inner skin, the outer skin and the reinforcing profiles are fixedly connected to form the body of the cover; the base of the rotating bracket is fixed on the edge of the body of the cover, and the rotary joint is fixed on the body; the quick release lock is fixed on the other edges of the body of the cover, and the cover is fixed on the body superior. The existing technology and the existing problems are: the inner and outer skins are connected by rivets, so that the cavity between the inner skin reinforcement socket and the inner surface of the outer skin is not sealed, and during the use of the mouth cover, water or other cor...
