A zipper head includes a lower ship plate and a upper ship plate; the lower ship plate is provided with chain teeth, and the upper end of the chain teeth is connected with a pull nose; a male tenon is arranged between the pull nose and the chain teeth; a female tenon fitted with a tenon is arranged on the upper ship plate; a positioning groove fitted with a pull nose is arranged at the end of the upper ship plate; when the male tenon is connected with the female tenon, the positioning groove is arranged. When the nose is clamped, a combined zipper head is formed between the dismounting plate and the boarding plate. The mortise and tenon on the upper and lower ship plates are connected by a mortise structure. The mortise is a wedge-shaped dovetail with a slightly wide head and narrow tail. The lower surface of the upper ship plate is provided with a wedge-shaped dovetail-shaped mother tenon of the same size as the mortise. The wedge-shaped dovetail and mother tenon with a wide end and a narrow end are compressed by a wedge after the combination. The combined part of the zipper head of the invention is more compact and firm. The zipper head of the invention has simple structure, is easy to install and replace, does not need to operate a special machine, and can be replaced manually directly, thus saving the time of installation and replacement.
【技术实现步骤摘要】
一种拉链头
本专利技术涉及一种皮具箱包用的拉链头。
技术介绍
皮具箱包是人们随身携带用于装置物品的常用工具。在长期使用的过程中,拉链反复开合与拉链头相互摩擦,会导致拉链头内腔磨损,间隙增大,而出现前拉后开和卡顿不畅。一旦拉链头损坏,箱包便无法使用。如果丢弃重新购买,既污染了环境又增加了经济负担。简单的处理办法是用钳子等工具捏夹拉链头,这种方法并没有解决根本问题。因为用钳子捏夹拉链头只是改变了拉链头内腔的高度,并没有改变拉链头内腔的宽度。拉链牙齿的咬合必须要靠拉链头内腔高度和宽度同时有相应精确的尺寸。如果用钳子捏夹拉链头过紧会卡坏拉链牙齿,过松仍会出现上述问题,人工的捏夹力度不好撑控。另一方面,拉链头大都釆用锌合金材质,比较脆,容易夹破。最好的办法是更换新的拉链头。现有的拉链头是一体成型的,而箱包拉链大多采用闭口结构缝合。要更换新的拉链头,必须先将拉链一端缝线拆开,装上新的拉链头后,再重新缝合拉链端部的缝线。这种更换拉链头的方法有很多弊端,如:拆线后无法按原来的线迹还原,影响美观;缝线颜色很难与箱包颜色适配,影响美观,没有专用机器无法更换,更换费时费力。
