Embodiment Construction

[0015] A quick release method for an aircraft engine compartment door and a latch lock according to the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for any limitation on the present invention.

[0016] Embodiments of the present invention: when adopting the quick release method of a kind of aircraft engine compartment door of the present invention to implement, as figure 1 and figure 2 As shown, the method is to open the lock by pressing the trigger, the bottom plate rotates under the action of the bottom plate torsion spring, and the connecting rod hinged on the bottom plate pulls the latch to retract, so as to quickly open the hatch; by pressing the bottom plate, the elastic force of the bottom plate torsion spring is overcome The base plate is reversely rotated, and the connecting rod hinged on the base plate pushes the latch to protrude, and at the same time, the l...

Abstract

The invention discloses a rapid demounting method for cabin door of aeroengine and a latch lock. The method comprises steps of: pressing a trigger to open the lock, a bottom plate rotating under effect of a bottom plate torsional spring, a connecting rod hinged on the bottom plate pulling the pin to retract to open the cabin door rapidly; pressing the bottom plate to overcome the torsional elasticforce of the bottom plate to rotate the bottom plate inversely, the connecting rod hinged on the bottom plate pushing the pin to extend, meanwhile the lock being hanged on a lock hanging scroll to lock the cabin door rapidly. The invention can satisfy requirement of rapidly opening and closing the cabin door of the airplane, which is convenient to maintain the airplane and improves maintaining efficiency of the airplane as well as reduces time of rapidly opening and closing the cabin door of the airplane. The latch lock of the invention mounted to the airplane is aligned with skin of the surface of the airplane, which does not affect aeroperformance of the airplane.

Description

technical field [0001] The invention relates to a quick release method and a latch lock for a cabin door, in particular to a quick release method and a latch lock for an aircraft engine cabin door. Background technique [0002] In order to meet the needs of high-efficiency operation of the aircraft, it is required that the maintenance time of the aircraft should meet the requirements of rapidity. However, it is not very convenient to open and reliably close the engine compartment door on the aircraft at present, and the time required for aircraft maintenance is relatively long. In addition, in order to realize the inspection and maintenance of equipment, systems and important components in the machine, there should be a good accessibility space. The hatch on the airframe is required to be as large as possible. In order to shorten the auxiliary time of maintenance work, the hatch is required to be quickly disassembled; in order to ensure the safety and reliability of the str...
