The invention relates to a traction device for a zipper. The traction device comprises a traction cable and a traction device, wherein the traction cable is connected with a zipper head of the zipper; a guide element for guiding the traction cable to adjust the orientation of the traction cable; and a winding device for winding the pulling cable to pull the zipper head. The pulling device is configured in such a way that during the pulling process, by means of the guide element, a portion of the pulling cable located between the zipper head and the guide element is oriented substantially parallel to a section of a zipper extension path through which the zipper head is about to travel, or an orientation deviation between the two is less than a predetermined value. By means of the guide element, the traction device of the present disclosure can adaptively adjust the orientation of the traction cable according to the orientation change of each section of the zipper extension path of the zipper. This not only helps the zipper to be easily zipped up, but also can prevent the zipper from being damaged at a position where the orientation of the zipper extension path changes.
本公开涉及一种用于拉链的牵引装置,包括:用于与拉链的拉链头连接的牵引线缆;用于引导牵引线缆以调整牵引线缆的取向的引导元件;和用于卷绕牵引线缆以牵引拉链头的卷绕设备。牵引装置构造成在牵引过程中借助于所述引导元件使所述牵引线缆的位于所述拉链头和引导元件之间的部分与所述拉链头即将行进通过的拉链延伸路径的区段处于基本平行的取向、或者使二者之间的取向偏差小于预定值。借助于引导元件,本公开的牵引装置可以根据拉链的拉链延伸路径的各区段的取向变化来适应性地调整牵引线缆的取向。这不仅有助于拉链被容易地拉上,而且还能够防止在拉链延伸路径的取向发生改变的位置处损伤拉链。
