Pressurizing prevention mechanism for aircraft pressurizing cabin
The invention belongs to the technical field of design of pressurization prevention mechanisms of aircraft pressurization cabins, and particularly relates to a pressurization prevention mechanism of an aircraft pressurization cabin, which is characterized in that a certain matching margin exists between a roller and a slotted hole in a pressure relief door lug after a cabin door is closed and a lock mechanism is locked; and the pressure relief door is opened by a certain angle through the elastic force of the first torsion spring and the second torsion spring and is gradually closed along with pressurization in the pressurization cabin, so that the requirement for machining and assembling precision is met, interference caused by machining and assembling errors is avoided, it is guaranteed that the locking mechanism can complete locking, installation and debugging are easy, and manufacturability is good.
本申请属于飞机增压舱增压预防机构设计技术领域，具体涉及一种飞机增压舱增压预防机构，其设计滚轮与泄压门耳片上长圆孔间，在舱门关闭，锁机构上锁后，具有一定的配合裕度，并利用第一扭力弹簧、第二扭力弹簧的弹性力使泄压门打开一定的角度，随着增压舱内增压逐渐关闭，以此对加工、装配精度的要求，避免由于加工、装配误差，导致的干涉，保证锁机构能够完成上锁，安装调试容易，工艺性较好。
