Abstract

本旋钮式窗帘开闭器为一种门窗五金。它由开关盒、传动杆及左、右支架组成,开关为旋钮式。当手旋动旋钮后,通过齿轮的传动和增速,使窗帘迅速开闭。同时,本开闭器设有齿轮换档机构,使开关能分别对内层和外层窗帘实行开闭控制,使操作更为方便。本开闭器适用于家庭、办公室、宾馆等。

Description

旋钮式窗帘开闭器
本发明为门窗五金。
现有的窗帘开闭器的功能一般为单层开闭,且大都是传统的绳拉式开闭法,虽结构简单,但使用不便,电动窗帘需耗电能,不够经济,为此,设计了本装置。
图1是本实用新型一种具体结构的示意图。
图2是图1沿A-A线的剖视图。
图3是图1沿B-B线的剖视图。
旋钮式窗帘开闭器由开关盒(1)、传动杆(2)及支架(3)、(6)组成。旋转启动旋钮(13),旋钮的转动便通过开关盒内一对伞形齿轮(11)、(12)的转向和增速后带动传动杆,传动杆的转动又通过支架(3)上的一对圆柱齿轮(8)、(9)的增速后带动小齿轮上端的皮带轮。在皮带轮与滑轮(5)之间装有牵引绳(4),以牵引窗帘作开闭运动。在开关盒内,设有档位开关(10),提上档位开关,其后端的U形叉即把传动杆提上,使齿轮(8)与齿轮(7)啮合,以驱动内层窗帘开闭。拨下档位开关,传动杆被拉下,使齿轮(8)与(9)啮合,可驱动外层窗帘开闭。由于在传动过程中设有二级齿轮增速,所以旋钮只需转动一周左右,窗帘即可作全程开闭运动。
旋钮式窗帘开闭器结构紧凑,操作方便,可用于单层或双层窗帘开闭。
旋钮式窗帘开闭器除轴类零件采用金属外,其余都采用工程塑料注塑加工成型。本设计加工及装配工艺简单,容易实现,材料成本低,易于推广。
