Abstract

自动关门装置是一种全新的建筑用的自动关闭门窗的装置。该装置结构简单，仅由一根与地面固定的带有人字形螺旋槽的心轴，通过钢珠与其组成螺旋付的浮动活塞，通过法兰盘固定到门窗上的外筒，在推(拉)门过程中蓄能，提供关门力的弹簧，堵盖等十几个另件组成。重量轻，仅为性能相同的地弹簧的1/10重，因而成本可大大降低，在翼扇上使用本装置可以实现里外开门，自动关门，关门时可加阻尼，开门至90°后可以停门，在高层建筑的窗扇上使用本装置还可解决擦玻璃难的问题。

Description

自动关门装置是一种建筑用的自动关闭门窗的装置。
通常所使用的关门装置有单管或双管弹簧合页或地弹簧（亦称地龙）以及液压阻尼合页，但结构都很复杂，重量很重（如地弹簧重量为9－10公斤），因而成本也较高（如地弹簧从几十元至几百元）。
本实用新型的目的是要提供一种重量轻（大约为地弹簧重量的1／10）结构简单（只十几个另件）因而成本可大大降低的一种全新装置。
该实用新型是这样实现的：主要部件是一根与地面固定的心轴，其上开有两道可供钢珠滚动的人字形滑槽，它与浮动活塞通过钢珠组成螺旋付。当钢珠在人字形部位，即门窗翼扇向内或向外开启角度不到90°时，依靠弹簧力翼扇可自动关闭；而当翼扇不须关闭时，即翼扇开至90°时，此时钢珠滑到人字形槽末端的水平段，翼扇失去自动关闭的作用，便停止运动。如开启一段时间，须关闭时，可将翼扇略微推动一下，使钢珠滑过人字形槽的平直段，进入人字形槽内，即可重新恢复自动关闭功能。
本实用新型的具体结构由以下的实施例及其附图给出。
附图1是本装置的结构原理图。
附图2是心轴滑槽的展开图。
该装置包括一根与地面固定的心轴6，外筒1，浮动活塞2，弹簧5，堵盖7组成。外筒通过法兰盘8与门窗的翼扇固定，心轴上有两道供钢珠3滑动的人字形螺旋槽，该槽的两端各有一平直段，以便钢珠在此段时，即翼扇开至90°时，失去自动关闭作用，处于停止状态。槽内有两粒钢珠，通过钢珠与浮动活塞组成螺旋付，钢珠是由浮动活塞上的孔及其内的柱销4限位。浮动活塞的两个平面与对称固定在外筒的滑块9相配合，以使外筒随翼扇的转动变为浮动活塞的上下平动，从而压缩了弹簧5，当推（拉）门的力消失后，压缩了的弹簧推着浮动活塞恢复原位，从而带动外筒旋转，翼扇便自动关上。当门不须关闭，即翼扇开至90°时，此时钢珠滑到人字形槽末端的平直段，翼扇失去自动关闭的作用，便停止运动；如须关闭，只须略微推动一下翼扇即可恢复自动关闭的功能。根据翼扇的重量及关门速度要求可设计不同弹力的弹簧相配套，以及采用心轴与堵盖间增加调整垫片方法调正弹簧预紧力，以达到不同关闭速度的要求。
为了进一步提高本装置的性能，可设计成带阻尼式的。其方法是将配合部分增加密封措施，在外筒内注满液压油。由于浮动活塞的存在将外筒分隔成两个油腔，在浮动活塞上开锥形单向阻尼孔。这样，当浮动活塞向下运动时，即门在推开的过程中油孔全开，不增加开门推力；当推门的力消失，门在压缩弹簧力的作用下复位过程中，浮动活塞上的阻尼孔关闭，上腔中的液压油缓慢地流至下腔中，以减轻关门时的冲击，实现阻尼作用，从而更符合人们的需要。
该装置结构小巧，可直接装在木门或空腹金属门内，也可装在高层建筑的窗扇上，以解决高层建筑擦玻璃难的问题。
