The base is arranged on the covering cap, the lock body is rotatably connected to the base, the elastic piece is used for enabling the lock body to rotate and lock, and the manual unlocking assembly is used for unlocking through manual operation of a user, so that when the air pressure in an aircraft cabin is too large, the air pressure acting on the covering cap can overcome the elastic force of the elastic piece; the covering cap drives the lock seat to move, the lock body rotates, and therefore the covering cap can be automatically opened for pressure relief. In addition, the manual unlocking assembly can be manually unlocked by a user, so that the same covering cap can be used as a pressure relief covering cap and a maintenance covering cap, and the structure of the cabin body can be simpler. Particularly, the lock body of the pressure relief lock is in a hook shape, an unlocking piece containing groove is formed in the inner side of the lock body, and the manual unlocking assembly is contained on the inner side of the lock body and in the unlocking piece containing groove, so that the pressure relief lock is small in overall size, small in space proportion in an aircraft cabin, capable of being well suitable for various cabin environments of various types and wider in application range.

    本发明提供一种包括设置在口盖上的基座、可转动地连接在基座上的锁体、用于使锁体转动锁止的弹性件、以及用于供用户手动操作开锁的手动开锁组件,因此在飞机舱体内气压过大时,作用在口盖上的气压能够克服弹性件的弹性力,使得口盖带动锁座移动、锁体转动,从而能够自动打开口盖进行泄压。此外,手动开锁组件也可供用户手动地进行开锁,使得同一个口盖可作为泄压口盖以及检修用口盖,可使得舱体结构更为精简。特别地,该泄压锁的锁体呈钩状,内侧有开锁件容置槽,手动开锁组件容纳在锁体内侧以及该开锁件容置槽内,因此本发明的泄压锁整体尺寸小,在飞机舱体中空间占比小,可很好地适用于多种机型的多种舱体环境,适用范围更广。
