Abstract

The present invention relates to a kind of roller shutter structure which can be retracted or set free up and down. It includes a support, a curtain and draw line. The upside of the curtain is fixed on the support. The drawing end of draw line passes through a limited slip machine fixed on the support. The another end of draw line strides to another end of the curtain from the underpart of the curtain, and it is connected with a cone. The slender end of the cone is embedded in a through hole of a fastener fixed on the support, and the thick end of the cone is clipped at the end of the through hole. An open slot is provided on the fastener along the lateral margin of the through hole and connected with the through hole. Location end of the draw line is connected with the cone, and the draw line is located by the cone and the fastener. When the outside force on the draw line exceeds 3 KGs, the cone can be automatically off with the fastener due to expanding of the through hole. Its structure is simple and secure.

Description

一种卷帘结构 技术领域： 本发明涉及日常生活用品技术领域， 特指一种可上下收卷的卷帘结 构。 背景技术： 窗帘作为一种曰常生活用品， 由于其具有调节室内光线强度、 美化室 内环境等许多功能， 目前广泛应用于家庭、 学校及办公室等场所。 尤其是 可上下收卷的卷帘， 更是深受人们的青睐。 上下收卷的卷帘是通过跨设于 窗帘两侧的收放拉线收放来实现窗帘的收卷叠合或下垂展开，在实际使用 时只需拉动收放拉线的拉伸端， 以致包夹窗帘的部分收放拉线的长度缩 短， 使窗帘由下端自动向上收卷的目的。 但是当前人们使用的卷帘其收放 拉线有一端固定连接在支架上，另一端穿设于止滑机构后延伸出外便于使 用者操作。 由于收放拉线设置于窗帘的两侧且为悬空式， 这样不管窗帘是 收卷或垂放，连接窗帘的部分收放拉线均成为一环套式，有时会套扣于人， 尤其是套扣小孩时则会造成无法预见的事故， 缺乏安全保障。 发明内容： 本发明的目的在于提供一种收放拉线受一定外力作用时可自动脱开， 安全性更好的卷帘结构。 本发明是通过如下技术方案实现的：收放拉线的拉伸端穿设于一固设 在支架上的止滑机构， 其另一端由窗帘的下端跨设至窗帘的另一侧， 并连 接一锥形体， 该锥形体的小端嵌入固设在支架上的扣体之通孔内， 而锥形 体大端卡于通孔的端部， 同时扣体上、 沿通孔侧缘开设有与通孔连通的开 口槽， 该开口槽位于通孔的正前侧， 且竖直设置。 所述锥形体的大端表面为球弧面，而锥形体的小端上设有系接收放拉 线的连接孔； 所述扣体为一塑胶成型体， 通孔之卡接锥形体大端的端部为 内凹；！犬。 本发明的收放拉线其定位端连接有锥形体，通过锥形体与扣体配合定 位收放拉线， 同时在一定外力作用于收放拉线时， 锥形体又可由扣体上安 全解扣， 其结构简单， 安全性好。 附图说明： 附图 1为本发明的结构示意图； 附图 2为本发明之扣体及锥形体的立体示意图； 附图 3为本发明的使用状态示意图。 具体实施方式： 见附图 1、 2、 3， 本发明包括有支架 1、 窗帘 2及收放拉线 3, 窗帘 2 上端固设于支架 1上，收放拉线 3的拉伸端穿设于一固设在支架 1上的止 滑机构， L :拉线 3的另一端由窗帘 2的下端跨设至窗帘 2的另一侧， 并 连接一锥形体 4。 锥形体 4的大端表面为球弧面， 而锥形体 4的小端上设 有系接 拉线 3的连接孔 41， 锥形体 4的小端嵌入固设在支架 1上的 扣体 5之通孔 51 内， 而锥形体 4大端卡于通孔 51的端部。 扣体 5为一塑 胶成型体， 通孔 51之卡接锥形体 4大端的端部为内凹状， 同时扣体 5上、 通孔 51正前侧沿通孔 51的方向竖直开设有与通孔 51连通的开口槽 52。 使用时， 拉动收放拉线 3的拉伸端， 以致夹设在窗帘 2两侧的部分收 放拉线 3的长度缩短， 窗帘 2下端在收放拉线 3的作用下自动向上收卷， 窗帘 2收卷到适当位置时再由止滑机构将收放拉线 3锁止即可。当悬空于 窗帘 2两侧的收放拉线 3套扣住其它物体而受到外来作用力作用时，连接 收放拉线 3一端的锥形体 4也相应受力逼压撑开扣体 5之通孔 51， 而扣 体 5之通孔 51 由开口槽 52往两侧胀开，以致锥形体 4的大端也可穿过通 孔 51下滑而脱开扣体 5的卡持， 收放拉线 3的相应端也即脱开定位， 收 放拉线 3环套解除而放开套扣物体， 避免意外事故发生， 尤其是避免了由 于小孩玩耍而被收放拉线 3悬扣住的危险发生。 本发明结构简单， 实用性强， 还可适用于其它上下收合式窗帘， 如百 叶窗帘、 罗马帘等。 Technical field of rolling shutter structure: The present invention relates to the technical field of daily necessities, in particular to a rolling shutter structure capable of being rolled up and down. BACKGROUND OF THE INVENTION Curtains, as a daily necessities, are widely used in homes, schools, offices and other places because they have many functions such as adjusting indoor light intensity and beautifying the indoor environment. Roller blinds that can be rolled up and down are especially popular. Rolling up and down the curtain is achieved by folding and retracting the retractable pull wires on both sides of the curtain to achieve the folding or folding of the curtain. In actual use, it is only necessary to pull the stretched end of the retractable pull wire so that the bag is clamped. The length of the part of the curtain retractable cable is shortened, so that the curtain is automatically rolled up from the lower end. However, at present, one end of a retractable pulling wire used by people is fixedly connected to a bracket, and the other end extends through the anti-sliding mechanism and extends out to facilitate user operation. Because the retractable pull cords are arranged on both sides of the curtain and are suspended, so whether the curtain is rolled or draped, the retractable pull cords that connect the curtains become a loop-type, sometimes it will be buckled on people, especially the buckle Children can cause unforeseen accidents and lack safety. SUMMARY OF THE INVENTION The object of the present invention is to provide a roller blind structure which can be automatically disengaged when subjected to a certain external force and has better safety. The present invention is achieved by the following technical solution: The stretched end of the retractable pull line is threaded through a non-slip mechanism fixed on the bracket, and the other end is straddled from the lower end of the curtain to the other side of the curtain and connected to a A cone, the small end of the cone is embedded in the through hole of the buckle fixed on the bracket, and the big end of the cone is clamped at the end of the through hole. At the same time, a communication is provided on the buckle along the side edge of the through hole. An open slot that communicates with the hole, the open slot is located directly in front of the through hole and is vertically arranged. The large end surface of the cone is a spherical arc surface, and the small end of the cone is provided with a connection hole for receiving a pull wire; the buckle is a plastic molded body, and the end of the through hole is connected to the end of the large end of the cone. The part is concave;! dog. The positioning end of the retractable cable of the present invention is connected with a cone, and the retractable cable is positioned through the cooperation of the cone and the buckle. At the same time, when a certain external force acts on the retractable cable, the cone can be safely released from the buckle. Simple and safe. Brief description of the drawings: Figure 1 is a schematic structural view of the present invention; Figure 2 is a schematic perspective view of a buckle body and a cone of the present invention; Figure 3 is a schematic view of a use state of the present invention. DETAILED DESCRIPTION: As shown in Figures 1, 2, and 3, the present invention includes a bracket 1, a curtain 2, and a retractable cable 3, the upper end of the curtain 2 is fixed on the bracket 1, and the stretched end of the retractable cable 3 is passed through a The anti-slip mechanism fixed on the bracket 1, L: the other end of the pull wire 3 is bridged from the lower end of the curtain 2 to the other side of the curtain 2, and is connected to a cone 4. The large end surface of the cone 4 is a spherical arc surface, and the small end of the cone 4 is provided with a connection hole 41 to which the pull wire 3 is connected. The small end of the cone 4 is embedded in the passage of the buckle 5 fixed on the bracket 1. Inside the hole 51, and the large end of the cone 4 is clamped to the end of the through hole 51. The buckle body 5 is a plastic molded body, and the end of the large end of the engaging cone 4 of the through hole 51 is concave. At the same time, the upper side of the buckle body 5 and the front side of the through hole 51 are vertically opened in the direction of the through hole 51. The opening 51 communicates with the hole 51. When in use, the stretched end of the retractable cable 3 is pulled, so that the length of the part of the retractable cable 3 clamped on both sides of the curtain 2 is shortened. The lower end of the curtain 2 is automatically rolled up by the retractable cable 3, and the curtain 2 is retracted When it is rolled into an appropriate position, the retracting and pulling wire 3 can be locked by the anti-slip mechanism. When 3 sets of retractable pull cords suspended on both sides of the curtain 2 buckle other objects and receive external force, the cone 4 connected to one end of the retractable pull cord 3 is also correspondingly forced to open the through hole 51 of the buckle 5 The through hole 51 of the buckle body 5 expands from the opening groove 52 to both sides, so that the large end of the tapered body 4 can also slide down through the through hole 51 to release the holding of the buckle body 5 and retract the corresponding wire 3 The end is also released and positioned, the retractable cable 3 loop is released and the buckle object is released to avoid accidents, especially the danger of being suspended by the retractable cable 3 due to children playing. The invention has a simple structure and strong practicability, and can also be applied to other up and down retractable curtains, such as jalousie, roman curtain, and the like.
