塞拉平移内倒门窗上的门窗扇下部连接装置
本技术涉及一种建筑物门窗上的的装置,尤其是一种塞拉平移内倒门窗上的下部连接装置。
技术介绍
目前,塞拉平移内倒门窗上的门窗扇下部连接装置有两种形式,一种是通过连接件、轴承直接固定在门窗扇上,支撑平移时的门窗扇重量。另一种是门窗扇在连接件、轴承上加装调整轴,虽能调整门窗扇与门窗框之间的间隙,但这种调整轴只能锁紧活动支臂,门窗扇与轴之间无法锁紧。当门窗扇滑动过程中发生撞击时,门窗扇与轴就发生错位。由于门窗加工过程中会存在加工误差,推门窗扇下部连接装置无法调节和锁紧,将导致门窗使用不顺畅,使用效果较差。
技术实现思路
本技术所要解决的技术问题是,提供一种塞拉平移门窗滑行门窗扇连接装置,以提高使用效果。本技术是这样实现的:塞拉平移内倒门窗上的门窗扇下部连接装置,它有连接座体,连接座上面纵向安装有螺杆轴,螺杆轴的下部有外螺纹、上部为连接轴头,连接座体内横向安装有紧固杆,紧固杆内端面为与螺杆轴外圆相对应的弧形凹槽,紧固杆的上侧面有V形凹槽,V形凹槽上方的连接座体上纵向安装有旋紧螺杆,旋紧螺杆的内端呈半球形或锥形,旋紧螺杆的外端有第一转动工具接头结构,旋紧螺杆的轴线与螺杆轴的间距小于V形凹槽最低点与螺杆轴的间距,螺杆轴的有外螺纹部位的直径大于连接轴头部位的直径,螺杆轴的上端有第二转动工具接头结构。所述的连接座体为连接角码。所述的第一转动工具接头结构、第二转动工具接头结构为转动工具插槽或转动工具插头。采用上述结构的门窗扇下部连接装置,结构合理 ...
