Problems solved by technology

When in use, it is necessary to use tools to open the screws or quick release bearing locks one by one, which reduces the quickness of use
At the same time, the waterproof glue makes the cover have a certain waterproof ability, but also increases the gap between the cover and the frame, making this gap the main channel for electromagnetic coupling

Embodiment Construction

[0016] As shown in the figure, the aircraft maintenance cover structure with electromagnetic protection function of the present invention includes an aircraft skin 9, a reinforced opening frame 6, a cover plate 1, a limit stopper 2, a dead bolt assembly 3 and a lock shaft 4, the The front of the cover plate 1 matches the skin of the theoretical shape of the aircraft. There is a countersunk lock hole 11 in the middle of the cover plate 1. There is a sunken L-shaped groove 12 on the back edge of the cover plate 1. In addition, a conductive rubber strip 8 is connected to the L-shaped groove. 12 matching, the limit stopper 2 is a groove-shaped part, riveted on the reverse side of the cover plate 1, the two sides of the limit stopper have limit flanges 21, and the center of the limit stopper 2 has a sunken hole 22. There is a conductive rubber ring 7 to match the sunken hole 22. The deadbolt assembly 3 is composed of a deadbolt 31 and a threaded bushing 32. There is a connecting hol...

Abstract

The invention discloses a covering cap structure for aircraft maintenance. The covering cap structure comprises an aircraft skin, a reinforced covering frame, a cover plate, a limiting check block, a lock tongue assembly and a lock shaft. A countersunk lock hole is formed in the middle of the cover plate, and a conductive rubber strip is matched with an L-shaped groove of the cover plate. A sunk hole is formed in the middle of the limiting check block, and a conductive rubber ring is matched with the sunk hole. The lock tongue assembly is composed of a lock tongue and a threaded bushing. The lock shaft is a self-locking screw and connects the cover plate with the lock tongue assembly. An inner hole of the reinforced covering frame is an inward-flanged flanging hole, and a sunk step matched with the L-shaped groove of the cover plate is formed between the flanging hole and the skin.

Description

technical field [0001] The invention belongs to the field of aircraft structure design, and relates to a maintenance cover for an aircraft with electromagnetic protection function. Background technique [0002] The access cover on the aircraft is used as a channel for equipment inspection, replacement and maintenance, which is related to the use and maintainability of the aircraft. The more flaps, the higher the opening rate of the aircraft, and the better the maintenance performance. However, the increasingly complex electromagnetic environment makes the gaps around the flaps become channels for electromagnetic waves to couple into the interior of the aircraft, which in turn affects the electronic equipment around the flaps. make an impact. Therefore, in the process of designing the cover, it is necessary to consider not only the quick release function of the cover, but also to ensure that the cover has an electromagnetic protection function. [0003] At present, the flap...
