Fireproof door closing device
The invention discloses a fireproof door closing device. The fireproof door closing device comprises a telescopic mechanism and a telescopic limiting mechanism. The telescopic mechanism comprises a first sliding rod and a second sliding rod which can slide relatively. A clamping piece is arranged on the first sliding rod. The end, away from the clamping piece, of the first sliding rod is a first installation end of the door closing device. An installation groove used for installing the telescopic limiting mechanism is arranged at one end of the second sliding rod. The other end of the second sliding rod is a second installation end of the door closing device. The second installation end is provided with a connecting piece. The telescopic limiting mechanism comprises an installation frame arranged in the installation groove. A first supporting block and a second supporting block are arranged between the installation frame and the second sliding rod. An electromagnetic assembly, a resetrelease part and an elastic part are arranged in the installation frame. The fireproof door closing device is simple in mechanical structure, convenient to implement, small in number of overall components, easy to assemble, high in production efficiency, capable of adapting to fireproof doors with larger door weight ranges, good in use effect and convenient to popularize and use, and the comprehensive cost of production, assembly, testing and the like is reduced.
本发明公开了一种防火门闭门装置,包括伸缩机构和伸缩限位机构,伸缩机构包括能够相对滑动的第一滑竿和第二滑竿,第一滑竿上设置有卡合件,第一滑竿远离卡合件的一端为闭门装置的第一安装端,第二滑竿的一端设置有用于安装伸缩限位机构的安装槽,第二滑竿的另一端为闭门装置的第二安装端,所述第二安装端上设置有连接件;伸缩限位机构包括设置在安装槽内的安装架,安装架与第二滑竿之间设置有第一支撑块和第二支撑块,安装架内设置有电磁组件、复位释放件和弹性部件。本发明机械结构简单,实现方便,整体组成部件少,组装简单,降低了其生产、组装和测试等综合成本,生产效率高,能适应更大门重范围的防火门,使用效果好,便于推广使用。
