Description

发动机门和闩锁组件
背景技术
现代的航空器可包括具有压力减轻系统的发动机。例如，突然的压力升高可在发动机的机舱隔室中发生，且这可导致该隔室中的应力，该应力可导致机舱构件的故障或机舱的不可接受的变形。因此，发动机通常特征在于用于压力减轻以防止对机舱构件的损坏的一些器件。
发明内容
在一个方面中，本发明涉及一种用于门的闩锁组件，该门枢转地安装至周围结构，以用于在打开位置与关闭位置之间枢转移动，该闩锁组件包括：闩锁保持件，其由门和结构中的一者承载，且具有位于撞击件承座(strike seat)内的可移除的撞击件；闩锁，其由门和结构中的另一者承载，且具有锁扣(catch)，该锁扣构造为接合该撞击件；和线缆，其具有固连至门和结构中的该另一者的第一部分、和承载该撞击件的第二部分。撞击件位于撞击件承座内且锁扣将接合该撞击件且将门闩锁在关闭位置中，从而确保线缆在门与该结构之间的联接。
附图说明
在图中：
图1是根据本发明实施例的门和闩锁组件的仰视图，其中门处于关闭位置。
图2是处于打开位置的图1的门的立体图。
图3A和3B例示出图1的闩锁组件的部分的立体图。
图4是在销安装在图1的闩锁组件的撞击件承座中之前的销的部分立体图。
图5A-5D是处于关闭位置的图1的门的视图。
图6A-6B是处于打开位置且作用为压力减轻门的图1的门的视图。
具体实施方式
图1例示用于门12的闩锁组件10，门22枢转地安装于周围结构14。将理解的是，门12可以以任何合适的方式枢转地安装于任何合适的周围结构，包括通过使用铰链16。例如，门12可枢转地安装于航空器发动机的机舱18的形成周围结构14的一部分。在此种实例中，门12可提供去往油罐的通路，且可枢转90°至完全打开位置，以便使用者可在发动机上具有去往油罐的通路。门12可枢转地安装，以用于在图1所示的关闭位置与图2所示的打开位置之间枢转移动。
图3A例示了闩锁保持件20，其可形成闩锁组件10的一部分且可由门12和周围结构14中的一者承载。闩锁保持件20的撞击件承座22可形成，以固持撞击件24(图3B)，该撞击件24可以可移除地接收在撞击件承座22中。在例示的示例中，闩锁保持件20与周围结构14可操作地联接。闩锁保持件20及其撞击件承座22可以以任何适合的方式形成。例如，撞击件承座22可包括用于接收撞击件24的钩26。在例示的示例中，撞击件承座22已示为包括一对间隔的钩26。钩26定向为使得各钩26与从关闭位置到打开位置的门12的枢转方向不对准地敞开。
图3B例示了闩锁30，其可形成闩锁组件10的另一部分且可由门12和周围结构14中的另一者承载。在例示的示例中，闩锁30由门12承载。锁扣32包括在闩锁30中，且构造为接合撞击件24。锁扣32可以是能够接合且固持撞击件24的任何适合的锁扣。
线缆34具有第一部分36，该第一部分36也固连至门12和周围结构14中的该另一者，且在例示的示例中与门12联接。线缆34的第二部分38承载闩锁组件10的撞击件24。撞击件24可采取任何合适的形式，包括撞击件24可包括销44。构想线缆34的第二部分38可具有第一和第二间隔的绳股(strand)40和42，其中销44跨过该第一和第二间隔的绳股40和42。如所例示的，第一和第二间隔的绳股40和42可延伸线缆34的长度，且第一和第二间隔的绳股40和42中的各个具有连接至销44的第二端和连接至门12的第一端。更具体而言，与第一部分36对应的第一和第二间隔的绳股40和42的第一端连接至门12的内表面。
当开始关闭门12时，如图4所示，使用者可将撞击件24放置到撞击件承座22中。当撞击件24位于撞击件承座22内时，使用者可关上门，这使锁扣32移动以接合撞击件24且将门12闩锁在关闭位置中，如图5A中所示的。如果撞击件24未由闩锁保持件20固持，则闩锁组件10不可被锁紧。这确保使用者必须将线缆34联接在门12与周围结构14之间，以便闩锁该门。图5B和5C示出了由闩锁保持件20固持的撞击件24和接合该撞击件24的锁扣的附加视图。而且，撞击件承座22的钩26可定向为使得销44与锁扣32的接触将销44压入撞击件承座22中，如在图5D中更清楚地看到的。
在销44已由撞击件承座22固持，且门12已大概关闭时，门12可移动至打开位置，且可作用为压力减轻门。如图6A中例示的，当门12移动至打开位置时，闩锁保持件20固持销44。图6B例示出当门12移动至打开位置时，钩26继续固持撞击件24。以此方式，闩锁组件10可能能够在闩锁位置与释放位置之间操作，在该闩锁位置处，门12被保持在关闭位置中，在该释放位置处，门12可枢转至打开位置。
上述实施例提供了多种益处，包括这些实施例确保线缆在门与结构之间的联接，使得当门作用为压力减轻门时，该线缆可限制门的打开角度，且保证在压力减轻过程期间不会发生任何损坏。在现代的航空器中，存在维护人员忘记加载门的压力减轻功能的潜在风险，且上述实施例可防止此种失察，因为这些实施例确保线缆连接在门与结构之间。
在尚未描述的范围内，各种实施例的不同特征和结构可以根据需要与彼此组合地使用。一个特征可能未在所有实施例中例示不意味着认为其不可这样，而是出于描述的简洁而做的。因此，不同实施例的各种特征可根据需要来混合和匹配，以形成新的实施例，不管新的实施例是否得到了清楚的描述。在本文中描述的特征的所有组合或排列由本公开覆盖。
本书面说明使用示例以公开本发明，包括最佳实施方式，并且还使任何本领域技术人员能够实践本发明，包括制造并且使用任何设备或系统并且实行任何合并的方法。本发明的可取得专利的范围由权利要求限定，并且可包含本领域人员想到的其他实例。如果这种其他实例具有不与权利要求的文字语言不同的结构元件，或如果它们包括与权利要求的文字语言无显著差别的等同结构元件，则它们意图在权利要求的范围内。
