Abstract

本实用新型适用于135平视取景(傍轴取景)照机机。
主要技术是用链臂将照相机的镜头盖与快门锁连接起来。当镜头盖揭开并移动至不遮住镜头时,链臂跟随偏转20°—30°的夹角,带动快门锁旋纽顺时针方向旋转,锁卡自动解除,可按动快门拍照。反之,将镜头盖盖上,快门锁则自动锁住。实现照相机的防空拍功能。

Description

本装置适用于平视取景照相机(傍轴取景相机)。
平视取景相机的镜头盖不打开也可取景,也可按动快门拍照,因此,容易造成空拍。
本实用新型的目的是设制一种装置,能使镜头盖与快门锁联动。当镜头盖盖好时,快门按纽被锁住,不能拍照。镜头盖揭开后,快门锁被解除,可以按动快门拍照。
本实用新型采用的方法是用链臂连接镜头盖与快门锁。链臂一端将快门锁卡定,另一端与镜头盖相联。当镜头盖处在关闭位置时,链臂将快门锁锁定;当取下并移动镜头盖时,能带动链臂旋转快门锁旋纽,快门锁打开。
该装置应用于照相机防空拍,能充分利用胶卷,不错过拍摄机会,不会丢失镜头盖,有利于镜头保护。小巧的不锈钢或电镀链臂增加了相机的外形观感。
下面利用附图所示的实施例作进一步说明。
图1    是链臂前后弯曲形状图
图2    是链臂垂直向下形状图
图3    是被链臂联接的快门锁和镜头盖打开时的形状图
图4    是被链臂联接的快门锁和镜头盖关闭时的形状图
图4所示像机上的镜头盖在镜头上,链臂一端与镜头盖联接,另一端与快门锁[1]联接。链臂可前、后弯曲(如图1箭头所示),从而能取下镜头盖(如图3)。链臂在水平方向位移小(如图2箭头所示),当取下镜头盖并移动至不遮住镜头时,链臂偏转20°-30°的夹角;由于链臂上的锁销[2]锁住快门锁,可使快门锁[1]旋转,打开锁卡。
