Locking Mechanism of Cabin Door and Its Alarm System

Abstract

The invention provides a locking mechanism of a cabin door and an alarming system of the locking mechanism of the cabin door and relates to the technical field of rotorcrafts. The locking mechanism of the cabin door and the alarming mechanism of the locking mechanism of the cabin door solve the technical problems that a locking mechanism of the cabin door is inconvenient to open and close and cannot remind people that whether the door is locked well or not, then flight danger is caused. The locking mechanism of the cabin door comprises a locking seat and a hooking connection piece. The locking seat is fixedly arranged on a cabin body. The hooking connection piece is movably connected to the cabin door. The locking seat comprises an installation seat and a clamping lock column. The hooking connection piece comprises a door inner handle, a hook, a door outer handle and a connecting shaft. A trigger portion is arranged on the hook. The locking mechanism of the cabin door further comprises the alarming system. The alarming system comprises a trigger switch, an electronic alarm and a control unit. When the hook is clamped to the clamping lock column, the trigger portion is in contact with and in connection with the trigger switch and used for switching off the electronic alarm. The locking mechanism of the cabin door and the alarming mechanism of the locking mechanism of the cabin door have the advantages of being simple in structure, tight in clamping, good in clamping effect and convenient to operate. The alarming system can remind people whether the cabin door is locked well or not and lower the flight risk.

Description

technical field [0001] The invention relates to the technical field of rotorcraft equipment, in particular to a locking mechanism and an alarm system for a hatch that can be used on a rotorcraft to quickly open or lock a hatch and give an alarm when the hatch is not locked. Background technique [0002] A gyroplane is a rotorcraft that uses the relative air flow to blow the rotor to rotate to generate lift. Its forward force is directly provided by the propeller driven by the engine. It is an aircraft between a helicopter and an airplane. It is equipped with a rotor and fixed wing surfaces. It has the characteristics of short take-off and landing distance, low-speed and low-altitude flight, simple and lightweight, and easy to conceal. [0003] The flight characteristics of the rotorcraft determine that the weight of the rotorcraft must be very light, so the cabin of the rotorcraft is not large and can only accommodate one or two people, and the cabin door is very close to t...
