Abstract

一种窗锁,由锁体、锁钩、锁扣组成,其原理是利用斜面的运动使锁钩转动,达到锁钩扣紧或松开锁扣的目的。其特征有一斜面结构的转臂6,斜面与锁钩4尾部端面接触,锁钩4安装在弹簧轴2上,并能转动,转臂转动,斜面随之而动,使锁钩绕弹簧轴2转动,锁钩就扣紧或脱离锁扣。

Description

窗  锁
窗锁是一种建筑用锁具,它由锁体、锁勾、锁扣组成。
现有窗锁种类很多,其目的都是使活动窗扣紧在窗框。现在通常使用的有二大类:一类像门插那样结构的插销式窗锁;另一类是锁勾式的半自动窗锁。插销式窗锁关窗时插锁不能自动扣住窗框,需要手帮助才能使插销扣紧窗框,所以不便于使用。自动窗锁关窗时可使锁勾自动扣紧窗框不再需要手的帮助,但现有自动窗锁的结构较复杂,零部件较多。
本实用新型“窗锁”目的是设计一种结构较简单,使用方便的“窗锁”。
“窗锁”的方案是减少开锁勾的力的传递零部件,零部件减少,结构就会简单,同时亦减少运动的阻力,开锁的力也就降低了。
窗锁的结构特征是有一斜面结构的转臂6。它绕轴7转动,该斜面与锁勾4尾部端面接触,斜面9的运动使锁勾绕弹簧轴2转动,使锁勾紧扣或松开锁扣,达到开关窗的功能。
本窗锁结构简单,开关方便省力。
现以一实施例阐明“窗锁”的结构特征。

图5是窗锁零件转臂主视图
图6是窗锁零件转臂俯视图
图7是窗锁零件转臂左视图
图8是窗锁零件锁扣主视图
图9是窗锁零件锁扣俯视图
窗锁(图1、2、3、4)由锁体1、弹簧轴2、扭簧3、锁勾4、拉簧5、转臂6、锁扣8组成。转臂(图5、6)只有斜面9,它绕轴7转动,斜面9与锁勾尾部端面接触(图4、5、6、7),锁勾装在弹簧轴2上,并能转动,当转臂转动时,斜面随之运动,在扭簧3的力和斜面9的力作用下,锁勾绕弹簧轴2转动,从而扣紧或脱离锁扣8(图8、9)
使用时,锁扣装在窗框上,锁体固定在活动窗上,开窗时,拔动转臂尾端(图3),使转臂转动,锁勾脱离锁扣,便可推动窗门;关窗时,只需往锁扣方向推窗门,锁勾碰撞锁扣后转动并进入扣紧状态。
本例窗锁简单、可靠、省力。
