Abstract

本发明属于航空技术领域,涉及一种特别适用于随动小口盖设计。本发明主要由1.小口盖、2.合页、3.大口盖、4.密封胶条等构件组成。对于一些重要接头螺栓连接,尤其发动机短舱,旁边有大口盖,若加大口盖面积,影响接头传力,而接头上的螺栓连接无通路。单独开口盖,构件多、占空间及赔重量,设计一种小口盖仅合页和小口盖,利用大口盖,关闭时压住小口盖,使小口盖不能打开,需要时打开大口盖,小口盖也随之开启,节省了小口盖快卸锁及连接,也利用空间。

Description

一种随动小口盖
技术领域
本发明属于飞机结构设计技术领域,涉及飞机随动小口盖。
背景技术
对于一些重要接头螺栓连接,尤其发动机短舱,旁边有大口盖,若加大口盖面积,影响接头传力,而接头上的螺栓连接无通路,单独开口盖,构件多、占空间及赔重量,设计一种小口盖仅合页和小口盖,利用大口盖,关闭时压住小口盖,使小口盖不能打开,需要时打开大口盖,小口盖也随之开启,节省了小口盖快卸锁,也利用空间。
发明内容
本发明的目的是:提供一种在满足结构强度的前提下,结构简单,操作方便、传力特性好,重量轻的一种机头、机尾对接螺栓防松装置。
本发明的技术方案是:一种随动小口盖,其特征在于,包括合页(1)、口盖蒙皮(2)、密封胶条(4),其中,合页(1)一端固定在机体结构上,另一端与口盖蒙皮(2)连接,口盖蒙皮(2)一端与合页(1)固定连接,另一端为下陷台阶式结构,其上粘有密封胶条(4),与大口盖(3)搭接,大口盖(3)关闭时压住小口盖,使小口盖不能打开。
本发明的有益效果是:提供一种在满足结构强度刚度的前提下,结构简单、元件少、重量轻,操作方便的随动小口盖设计。能够实现借助大口盖开启小口盖,便于接头螺栓的安装与拆卸,一件多用,解决狭小空间螺栓的安装检测问题。
附图说明
图1为本发明一种随动小口盖设计示意图;
其中,合页(1)、口盖蒙皮(2)、大口盖(3)、密封胶条(4)。
具体实施方式
下面结合附图对本发明和实施方式做详细说明。
参见图1
本发明一种随动小口盖按下列步骤进行:
首先将装配好的小口盖连接在接头螺栓连接处。
对于一些重要接头螺栓连接,尤其发动机短舱,旁边有大口盖,若加大口盖面积,影响接头传力,而接头上的螺栓连接无通路,单独开口盖,构件多、占空间及赔重量,设计一种小口盖仅合页和小口盖,利用大口盖,关闭时压住小口盖,使小口盖不能打开,需要时打开大口盖,小口盖也随之开启,节省了小口盖快卸锁,也利用空间。最后利用大口盖关闭时将将小口盖固定。上下口框的设计保证外蒙皮齐平。
