The invention relates to a pull-stop type sunshade curtain. The pull-stop type sunshade curtain comprises a frame assembly, a sliding rail, curtain cloth, a sunshade curtain cross beam, a scroll, a sliding block and a roller mechanism, the roller mechanism comprises a winding roller, a torsion spring, a torsion spring fixing block, a winding roller group and a pull wire; the direction of the sunshade curtain scroll force is changed through a pull wire and a roller; force balance is achieved on the sliding block, the sliding block can stop at any position on the sliding rail, the effect that the sunshade curtain can stop immediately after being pulled is achieved, the structure is simple, mounting and dismounting are convenient, only system friction force between the sunshade curtain sliding block and the sliding rail and torsion of the torsion spring need to be overcome when the sunshade curtain is opened, and operation is convenient. Reel force is achieved through pre-tightening of the torsion spring (acting of the torsion spring), the sunshade curtain is opened and closed through pushing force with different hand feelings by changing different pre-tightening states of the torsionspring, namely adjusting the magnitude of operating force, and meanwhile the reel force is changed, so that the sunshade curtain can achieve different tightening or gentle display modes.

    本发明涉及一种即拉即停式遮阳帘。一种即拉即停式遮阳帘,包括框架总成、滑轨、帘布、遮阳帘横梁、卷轴、滑块和滚轮机构,滚轮机构包括绕线滚轮、扭簧、扭簧固定块、绕线滚轮组和拉线,遮阳帘卷轴力通过拉线和滚轮改变力的方向,在滑块上达到力的平衡,实现滑块在滑轨上的任意位置停止,即实现遮阳帘即拉即停的效果,结构简单,安装与拆卸方便,开启遮阳帘只需要克服遮阳帘滑块与滑轨的的系统摩擦力以及扭簧扭力,操作方便;卷轴力通过扭簧的预紧来实现(扭簧做功),通过改变扭簧预紧的不同状态,即通过调整操作力的大小,实现通过不同手感的推动力来开启和关闭遮阳帘,同时改变了卷轴力,使遮阳帘可以实现绷紧或者平缓的不同展现方式。
