Ground opening and closing device for aircraft canopy

Abstract

The invention discloses a ground opening and closing device for an aircraft canopy, and belongs to the technical field of aeronautic equipment. The ground opening and closing device comprises a movable handle, a screw rod, a sleeve and a screw. The outer side face of a trigger nut is sleeved with a regular polygon through hole of the sleeve; the screw rod is sleeved with the sleeve; and the external thread section of the screw rod is in hole-shaft fit with the internal circumferential face in an annular limiting boss on the sleeve. The movable handle is fixed to a radial through hole of the guide section of the screw rod; the external thread section and the trigger nut are in threaded connection; and the external thread section of the screw rod and the trigger nut are screwed by rotating the movable handle. After the screw rod and the trigger nut are screwed, the screw penetrates through the sleeve to be tightly screwed on the outer circumferential face of the locking section of the screw rod, and therefore the screw rod and the sleeve are fixedly connected. The ground opening and closing device can guarantee that the aircraft canopy can be smoothly opened and closed on the ground, is simple in structure, portable, stable in performance and reliable in using, and can not damage other parts in an aircraft canopy body in the using process.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment, and in particular relates to a ground opening and closing device for an aircraft canopy. Background technique [0002] The aircraft canopy needs to be manually opened and closed during the repair process. This process needs to be completed with a control switch hidden inside the aircraft body that comes with the aircraft canopy. The switch is a trigger nut that drives the rest of the body to complete. During the repair process, the canopy can be opened and closed repeatedly according to the repair content and progress. [0003] The canopy canopy is manually opened and closed. The switch is located at the lower part of the rear end of the canopy and is built into a set of mechanisms inside the body. The opening form of this mechanism is that a trigger nut drives the other mechanisms to achieve the opening and closing of the canopy. Hidden inside the aircraft, it is difficult to accurat...

Problems solved by technology

[0003] The canopy canopy is manually opened and closed. The switch is located at the lower part of the rear end of the canopy and is built into a set of mechanisms inside the body. The opening form of this mechanism is that a trigger nut drives the other mechanisms to achieve the opening and closing of the canopy. Hidden in the interior of the aircraft, it is difficult to accurately dock and easily damage other internal parts of the mechanism when directly intervening in the screw to screw it in
