Small quick-release waterproof cabin door

Abstract

The invention discloses a small quick-release waterproof cabin door which comprises a cabin door body and a fixing part, a groove is formed in the fixing part, a sliding block is arranged in the groove, one end of the sliding block is connected with the cabin door body, a hook lock is arranged between the cabin door body and the fixing part, and a sealing ring is arranged in the periphery of the cabin door body. The sealing ring is of tubular hollow rubber and has high elasticity, after the cabin door is closed, the edge of the fixing part has certain extrusion force on the sealing ring, the hollow rubber is pressed to deform and is tightly attached to the fixing part, rainwater can enter position outside of the sealing ring but cannot cross the sealing ring, the rainwater flows downwards along the outside of the sealing ring of the cabin door, and is finallydischarged out of the equipment cabin through a lower opening frame of the cabin door; By means a boss, the pressure intensity of the cabin door and the fixing part on the sealing ring can be better increased, the deformation amount of the sealing ring is larger, the sealing performance is better. According to the invention, the structure is simple, operation is easy, the weight is light, opening and locking are rapid and convenient, the cabin door pressing force is large, the reliability is high, maintenance is convenient, and the waterproof performance is high.

Description

Technical field [0001] The present invention belongs to the field of aircraft mechanism design, and specific relates to a small fast-moving waterproofing. Background technique [0002] As the efficiency of the aircraft uses, the time and the number of time required for the aircraft and the number of mechanical personnel have been given higher requirements. For equipment cabins that need to be maintained frequently, local staff can quickly open and close the door, open the door, not separated from the plane, usually have electronic devices or engine accessories in the equipment cabin, do not have in flight and parking Rainwater enters the equipment cabin, so a higher waterproof requirement for fast-moving cabins. The existing equipment hatch is usually used with a hinge, a C-shaped support as a rotating member, and is compressed with a tab or a top-pressed fast unload lock, a strut or an air spring or the like as a support for the opening state of the hatch. . In order to meet the...

AI Technical Summary

Problems solved by technology

The waterproof performance of the hinged hatch is difficult to meet, and additional waterproof measures need to be added, and the hinge can only be arranged on the straight section of the fuselage, which has great limitations; in order to ensure the opening of the hatch, the crank arm needs to be If it is bigger, it will take up a lot of space inside the aircraft
