Description

推拉门窗锁
本实用新型属于推拉式门窗的关锁装置,特别适用于铝合金门窗上使用。
现有的铝合金门窗上使用的推拉式门窗锁,都为纵向往复运动式的结构,在锁体上设有可纵向往复运动的活动锁芯,例如中国专利ZL93217822.7,“推拉门窗保险锁”;中国专利ZL94204956.X,“推拉门窗锁”。该类锁结构比较简单,锁扣与锁钩(锁舌)碰撞时,碰撞冲击力的向下分力对活动锁芯产生力矩,向内分力冲击活动锁体(滑块),因而碰撞不灵活,容易损坏。
本实用新型的目的是提供一种碰撞灵活的推拉式门窗碰锁。
本实用新型的目的由如下技术方案来完成:包括锁体、滑块、锁舌、锁扣,该滑块在锁体上可往复上下移动,该锁体连接外锁壳和内锁壳,该外锁壳和内锁壳各设有拉手坑,锁体的侧向还连接固定板,在所述的内锁壳上设有旋纽,该旋纽与内凸轮连接,该内凸轮与所述滑块的坑洞配合,旋转旋纽推动滑块上下移动,在所述的外锁壳上设有锁芯,该锁芯连接外凸轮,该外凸轮与滑块的阶壁抵触配合,转动锁芯带动滑块向下移动,所述的锁舌设在滑块的边侧,在锁体上边侧设上导向孔并与锁舌配合,在锁体下边侧设下导向孔并与锁舌的根部配合,复位弹簧设在锁舌根部与锁体之间。
上述的锁体与外锁壳、内锁壳、固定板用螺钉固紧为一整体,锁体上的机构,如上导向孔、下导向孔,可转设在固定板,或外锁壳、内锁壳上,效果作用等同。
本实用新型因限位导向机构直接限位锁舌,使锁舌与锁扣碰撞时,碰撞作用力转化为使锁舌向下移动的分力,而向内冲击分力则直接由导向孔壁承受,并且避免了向下分力作用于锁舌产生的力矩,以致滑块及锁舌移动平稳,不会偏转,碰撞灵活,不易损坏。

图2为本实用新型实施例侧向剖视结构图
图3为本实用新型实施例外型图
图4为本实用新型实施例侧向外型图
下面结合附图进一步描述实施例:
锁体4两侧为内锁壳11和外锁壳12,滑块3在锁体4上可上下移动,内锁壳11和外锁壳12各设有拉手坑17。锁舌6安装在滑块3的侧边,在锁体4的侧向设有固定板10,两者经螺钉连接,固定板10为铁板冲压而成,上导向孔5正好由固定板的锁舌孔处料冲压成型。下导向孔9设在锁体4上。在内锁壳11的拉手坑部位设旋纽16,该旋纽经轴穿过内锁壳与内凸轮15联接。该内凸轮与滑块的坑洞2配合,旋转旋纽推动滑块上下移动。在外锁壳上设有锁芯14,锁芯14也联接外凸轮13,该外凸轮13与滑块上的阶壁1抵触配合,旋转锁芯,外凸轮推动滑块向下移动,锁舌脱开锁扣;再旋转锁芯,外凸轮脱开阶壁1,滑块在复位弹簧7作用下向上移动,回复原位。锁舌经上导向孔限位导向,锁舌根部经下导向孔9限位导向。锁舌根8外套有压缩弹簧7,位于下导向孔座上。锁扣18与锁舌碰撞配合。
