具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域的技术人员理解。
附图1-2示出了本发明的一种收放式窗帘，具体为一种收放式的罗马帘。参照附图1-2所示，收放式窗帘包括帘体100、带动帘体100收放的拉绳200、用于窗帘拉绳200收放的收放装置300、用于调节拉绳200可穿设在帘体100中的长度的调节装置400。拉绳200穿设在帘体100中，拉绳200的下端通过调节装置400和帘体100的下端部固定连接、上端部和收放装置300固定连接实现收放。
参照附图1-5所示，一种用于窗帘拉绳的调节装置400，包括固定连接在帘体下端的安装座1，安装座1上开设有用于供拉绳200穿过的第一穿绳孔，安装座1上设置有安装槽10，第一穿绳孔开设在安装座1的槽壁上。该调节装置400还包括用于卷绕固定拉绳200的卡止件2，卡止件2的中部贯通开设有用于供拉绳200穿过的绕绳孔20，卡止件2可脱离地卡设在安装槽10内，且安装槽10的槽壁和卡止件2之间具有容纳绕在卡止件2外表面上的拉绳200的间隙。
具体到本实施例中，安装座1包括片状的本体11、自本体11的下部向外延伸的一圈凸缘12、自本体11的上端向外弯折延伸的翻边13，本体11、凸缘12和翻边13一体成形。本体11的下端和帘体100的下端固定连接。凸缘12和位于凸缘12之间的本体11构成上述安装槽10，凸缘12的内壁即为安装槽10的侧壁，位于凸缘12之间的本体11的表面即为安装槽10的槽底。本体11自下至上依次开设有第一穿绳孔、第二穿绳孔110，第一穿绳孔对应安装槽10开设，即第一穿绳孔开设在安装槽10的槽底上。第二穿绳孔110位于第一穿绳孔正上方且二者的中心线相平行。翻边13上开设有第三穿绳孔130，第三穿绳孔130位于第二穿绳孔110及第一穿绳孔的正上方，三个穿绳孔线性排列。拉绳200自上至下依次穿过第三穿绳孔130、第二穿绳孔110、第三穿绳孔130后穿至安装槽10内。
卡止件2大体呈空心的圆台状。卡止件2的外表面包括相对的内底面21和外底面22、位于内底面21和外底面22之间的侧表面23，卡止件2的内表面则由上述绕绳孔20的孔壁201构成，绕绳孔20自内底面21至外底面22贯通卡止件2，绕绳孔20的中心线和卡止件2的中心线基本重合，且在卡止件2卡在安装槽10内时，绕绳孔20的中心线与安装槽10的中心线向平行或重合，拉绳200至少在卡止件2的外表面和内表面上绕设一圈。内底面21位于卡止件2的靠近安装槽10的底壁的一端上。
侧表面23自内底面21至外底面22以逐渐远离穿绳孔的中心线的方式倾斜延伸，即，卡止件2的侧表面23为斜面，便于将卡止件2卡入或脱离安装槽10。
绕绳孔20的孔壁201上等间隔开设有四个自内底面21至外底面22贯通孔壁201的线槽202，外底面22上也对应开设有四个自绕绳孔20的孔壁201至侧表面23贯通外底面22的线槽220，绕绳孔20的孔壁201上的各线槽202和对应的外底面22上的线槽220相接。拉绳200自第一穿绳孔穿出后进入绕绳孔20内，拉绳200沿绕绳孔20孔壁201上的其中一个线槽202绕至卡止件2外底面22上对应的线槽220并自卡止件2侧表面23、内底面21绕回至绕绳孔20内，然后拉绳200穿出绕绳孔20或自绕绳孔20孔壁201的另一线槽202重复上述步骤。
需要调节拉绳200的长度时，将卡止件2自安装槽10中拔出，调整绕绳位置，直至达到期望的拉绳200穿设长度后，将绕紧有拉绳200的卡止件2卡入安装槽10内，由于安装槽10对卡止件2及拉绳200的限位，使得拉绳200下端被固定，拉绳200保持设定好的长度。
