一种双向月牙锁
本技术涉及一种门窗锁,特别涉及一种双向月牙锁。
技术介绍
月牙锁广泛用于塑钢铝合金推拉窗上。推拉窗的开启和关闭的五金件就是月牙锁。因其形状像月牙,故行内人称之为月牙锁。月牙锁不但起到开启关闭的作用,在一定程度上也起到防盗的功能。现有技术的月牙锁一般采用螺丝安装,其螺丝裸露在外面,影响门锁整体视觉效果,而采用其他方式安装,则存在着安装不牢固的问题。
技术实现思路
为了解决现有技术的问题,本技术提供了一种双向月牙锁,它结构简单,安装底座的螺丝孔能被旋转的上盖盖住,便于安装且美观大方。本技术所采用的技术方案如下:一种双向月牙锁,其特征在于:它包括一个空心转轴,月牙锁片、压簧、上盖、底座和垫片从上到下依次叠加套装在空心转轴上,其中,月牙锁片与空心转轴固定连接并随空心转轴同步旋转,上盖被压簧压紧在底座上,上盖和底座可绕空心转轴360度旋转,底座上设有两个往门窗上安装的螺钉孔,空心转轴上端有圆顶,圆顶左右两侧设有卡槽,手柄的前端有扣在圆顶上的端帽,端帽的内侧有与卡槽相对应的两个卡条,穿过空心转轴的螺丝与端帽中心的螺纹孔相连接,在螺丝上安装的弹簧将端帽弹性地扣在圆顶上并由相互嵌套的卡槽和卡条限位。进一步,在底座的上面设有环形定位凸条,上盖下面的外沿扣在凸条的外侧。本技术提供的技术方案带来的有益效果是:1)在底座上面设有由压簧压紧的上盖,上盖可绕空心转轴360度旋转,在安装时,旋转上盖露出螺钉孔把本技术固定在门窗边框上,安装好了之后旋转上盖使其扣在底座上,螺钉孔被盖住,浑然一体,美观大方,安装也很方便,进一步,在底座的上面设有环形定位凸条,上盖下面的外沿扣在凸 ...
