Problems solved by technology

[0002] In the past, the cockpit doors of agricultural and forestry aircrafts were: front-turning type—similar to the side opening of a car, which is greatly affected by the side wind load and limited field of vision; Good, but not convenient enough to board the plane and the door poses a safety hazard to the boarding crew
The traditional cabin door frame adopts hard polyurethane foam filled structure, which has poor sightlines, and its sealing is in the form of aviation sponge rubber plate, which has an unsatisfactory sealing effect

Embodiment Construction

[0023] Such as figure 1 , 2 As shown, the structural form of the door is: including the door frame 2 and the door glass 3 inside the door frame, the door frame 2 is a welded part of the aluminum panel 22 and the hat profile skeleton 21 . Such as figure 2 As shown, the hatch frame 21 is welded by a cap profile straight section 211 and a cap profile U-shaped section 212, and two insert rod supports 213 and a lock shaft support for latch rod installation are welded on the hatch frame 21. A corner box 214 used, and two second handle connecting pieces 215 used for fixing the cabin door switch, the second handle connecting piece 215 connects the second handle 6 (as Figure 9 shown). The hatch glass 3 is a non-shattering safety aviation plexiglass with a thickness of 3 mm. The door frame 2 on the lower edge of the hatch door is provided with two hinges 5, which are connected to the steel frame 17 of the fuselage through the two hinges 5, and the door frame 2 on the left side of ...

Abstract

The invention provides a glass compartment door structure of an agriculture and forestry plane. The glass compartment door structure comprises a door frame and compartment door glass arranged in the door frame, and is characterized in that the door frame is a welded piece formed by welding an aluminum panel and a cap type profile frame; a compartment door frame is formed by welding a cap profile straight section and a cap profile U-shaped section; the compartment door glass and the door frame are screwed with each other through battens after being overlapped; rubber plates 0.5 mm in thickness are respectively adhered to two sides, which are in contact with the door frame, of the compartment door glass; screw connection holes are formed in the compartment door glass; rubber linings are mounted on screws during connection; the surrounding of the door frame is covered with tubular rubber sealing profiles; an antitheft lock is arranged at the upper side of the door frame; an antitheft lock seat is mounted on a steel structure of a plane body. The glass compartment door structure is high in buffering property, high in durability, convenient to turn over and favorable for boarding.

Description

technical field [0001] The invention relates to a glass cabin door structure of an agricultural and forestry aircraft, which belongs to the technical field of aircraft cabin doors. Background technique [0002] In the past, the cockpit doors of agricultural and forestry aircraft were in the following forms: front-turning type - similar to the side opening of a car, which is greatly affected by the side wind load and the field of vision is limited; up-turning type - its airtightness and appearance quality are better Good, but not convenient enough to board the plane and the door is a safety hazard for the boarding crew. The traditional cabin door frame adopts a hard polyurethane foam filled structure, which has poor sightlines, and its sealing is in the form of an aviation sponge rubber plate, which has an unsatisfactory sealing effect. However, the downward-turning glass hatch structure has a wide field of vision and is convenient for the driver to work. The sealing form is...
