Abstract

电控窗帘机,是通变压器及二极管将民用交流电变为直流电,也可用电池驱动直流电机,电机使蜗轮蜗杆转动,蜗轮侧面有一绕线辊,绕线辊与滑轮上缠有拉线,拉线由拉簧张紧,由正反向开关控制拉线的运动方向,使挂在横杆上的窗帘布张开与合拢。

Description

属生活日用品窗帘机类。
现有的电动窗帘机,是通过电机驱动一个带正反向螺纹的螺杆转动,使挂在横杆上的窗帘布张开与合拢,螺杆比较难于加工及运输。
本实用新型的目的是,设计出一种线拉式的电控窗帘机。
图1是本实用新型的结构示意图,图2是电路图。
窗帘布通过金属环挂在横杆2上,横杆下面一侧固定一滑轮1,另一侧有一由电机6驱动的蜗轮蜗杆付5,蜗轮一侧有一绕线辊,绕线辊与滑轮1相对应缠绕一拉线3,拉线3通过拉簧4拉紧,窗帘布的内侧两边固定在上下拉线3上。窗帘下侧墙上固定有电控部分,其上面的变压器9及整流二极管,将民用的交流220伏电变为直流6伏电源,供电机6转动,电源开关7控制电路的接通,正反向开关8控制电机6的正反转动,以达张开与合拢窗帘的目的。在电控部分中还有一个与电机联接的插座10,当停电时或无电地区,可采用电池驱动电机。

Claims (2)
