The invention belongs to the technical field of design of aircraft cabin door opening keeping mechanisms, and particularly relates to an aircraft cabin door opening keeping mechanism which is characterized in that a torsion spring is used for keeping the position, when a cabin door is opened, the head of a lock hook is hooked into a lock groove by means of extrusion of a second support, automatic locking of the cabin door is achieved, and when the cabin door is closed, the head of the lock hook is locked. The control handle is used for controlling, the head of the lock hook is separated from the lock groove, the overall structure is simple, in the transmission mechanism, the idler wheel and the long round hole are used for transition, movement allowance is achieved, the requirement for machining and assembling precision can be lowered, interference to opening and closing of the cabin door is avoided, abrasion caused by long-term use of parts can be compensated, and the service life of the cabin door is prolonged. And the cabin door can be reliably locked at the opening position.
本申请属于飞机舱门打开保持机构设计技术领域，具体涉及一种飞机舱门打开保持机构，设计利用扭力弹簧进行位置保持，在舱门打开时，借助第二支座的挤压，使锁钩的头部钩到锁槽中，实现对舱门的自动锁定，在对舱门进行关闭时，以操纵手柄进行操纵，使锁钩的头部脱离锁槽，整体结构简单，且传动机构中，以滚轮、长圆孔进行过渡，具有活动裕量，可降低对加工及其装配的精度要求，避免对舱门的打开、关闭发生干涉，并能够补偿部件间长期使用发生的磨损，能够将舱门可靠的锁定在打开位置。
