[0001] 本发明涉及一种拉链， 尤其涉及一种双层拉链。  [0001] The present invention relates to a zipper, and more particularly to a double zipper.
背景技术  Background technique
[0002] 现有技术领域中的拉链， 均是由单层的连续排布的拉链齿， 通过上方的牙头或 上下方的锥状牙头互相咬合而成的。 对牙头的要求及牙齿排布的紧密度要求非 常严格。 因为牙齿的牙头小或排布太疏松， 拉链会出现爆链 （左右牙齿非正常 分离） 。 而牙齿的牙头大了或高了， 牙齿的排布太紧密了， 拉链会卡住难拉甚 至拉不动。 更为重要的是， 因为现有技术领域中的拉链均为锥状牙头的单层扣 合结构， 致使其受到尖锐物件撞击或尖锥状 （例如一支圆珠笔） 的锐物刻意撬 幵吋， 就会轻易的被挠幵， 从而令拉链左右两排链齿分解， 即拉链就会爆幵而 失去锁合的功能。 此前网上广为流传的， 用一支圆珠笔即可轻易撬幵一个锁了 密码的行李箱就是这个道理。  [0002] The zippers in the prior art are all formed by a single layer of continuously arranged zipper teeth, which are engaged with each other by an upper tooth or a top and bottom tapered tooth. The requirements for the head and the tightness of the arrangement of the teeth are very strict. Because the teeth of the teeth are small or the arrangement is too loose, the zipper will explode (the left and right teeth are abnormally separated). The teeth of the teeth are big or tall, the teeth are too tightly arranged, and the zipper will get stuck and hard to pull. More importantly, because the zippers in the prior art are single-layer fastening structures of tapered teeth, they are deliberately sharpened by sharp objects or pointed cones (such as a ballpoint pen). , it will be easily scratched, so that the two rows of chain teeth on the left and right sides of the zipper will be decomposed, that is, the zipper will explode and lose the function of locking. Previously, it was widely circulated on the Internet. It is just a matter of using a ballpoint pen to easily lock a suitcase with a password.

[0035] 本发明提供一种双层拉链可包括多种生産形式： 第一种是通过连续冲压拉伸模 具， 将指定形状的扁线类形金属材料制作成单组牙齿的形状， 再结合一***的 表面去毛刺及表面光泽度处理 （或按需求电镀成所需的金属表层颜色， 然后通 过逐齿排植的方式， 排植在拉链带上。 第二种是可溶铸类金属作原料， 通过压 铸模具浇铸成单组牙齿的形状， 再经过表面祛毛刺、 研磨、 电镀表层颜色后， 通过逐齿的方式排植到拉链带上。 第三种是通过注塑模具内嵌的制作牙组形状 ， 并预留好拉链布带的送料模形， 将拉链带送入注塑模具内， 再一次性将多组 的牙齿溶注在拉链带上。 [0035] The present invention provides a double-layer zipper that can include a variety of production forms: The first is to form a flat-shaped metal material of a specified shape into a single set of teeth by a continuous punching and drawing die, and then combine one The surface deburring and surface gloss treatment of the system (or electroplating into the desired metal surface color as required, and then planted on the zipper tape by means of tooth-toothing. The second is the soluble cast metal as raw material. The shape of a single set of teeth is cast by a die-casting mold, and then the surface is burred, ground, and plated, and then placed on the zipper tape by tooth-by-tooth. The third type is a tooth set embedded in an injection mold. shape And reserve the feeding pattern of the zipper tape, feed the zipper tape into the injection mold, and then dissolve the multiple sets of teeth on the zipper tape at one time.
[0036] 本发明提供的双层拉链， 其扣合齿部带有对向不对称的两个带有扣合功能的结 构， 板块与扣合齿部以错位形式排布。 因板块只负责控制拉链的水平方向不会 发生错位， 所以板块则无须带有扣合结构。 位于一对拉链带两侧的两个扣合齿 部与两个板块形成扣合后， 拉链就会形成坚固的板块式扣合装置， 该拉合结构 是非常坚固可靠的， 不会像传统拉链在受到尖锐物件的撬动或整条拉链在强力 扭曲吋会産生爆牙的情况。 此外， 基于本发明中的拉链牙齿已非传统的单个细 长牙齿的形式， 而是板块式的结构理念， 令本发明的拉链牙齿间有间隔或无间 隔的设计， 而两层 （正、 反两面） 的可塑性更是无限多的， 使得日后的拉链可 以具备更多的设计原素 （包括文字、 图案及更多的组合构成的综合体） 。 再次 ， 本发明的生产创作工艺局限性很低， 可通过金属冲压拉伸而成， 又可通过金 属压铸方式铸造而成， 也可通过塑胶浇注方式注塑成形制造， 令本发明无论是 原材料的选取、 生产制造方式的取向也是自由度很大的。  [0036] The double-layer zipper provided by the present invention has a structure in which the engaging teeth have opposite abutting functions with a snapping function, and the plate and the engaging teeth are arranged in a dislocated form. Since the plate is only responsible for controlling the horizontal direction of the zipper, it will not be misaligned, so the plate does not need to have a fastening structure. The two snap-on teeth on the two sides of the pair of zipper straps form a snap-fit with the two slats, and the zipper forms a sturdy slab-like snap-fit that is very rugged and reliable, unlike traditional zippers. When a sharp object is shaken or the entire zipper is twisted strongly, a tooth may be generated. In addition, based on the fact that the zipper teeth of the present invention have been in the form of a non-traditional single elongated tooth, but a plate-like structural concept, the zipper teeth of the present invention have a spaced or non-spaced design, and two layers (positive and negative) The plasticity of the two sides is even more infinite, so that the zipper in the future can have more design elements (including a combination of words, patterns and more combinations). Thirdly, the production creation process of the invention has low limitation, can be formed by metal stamping, can be cast by metal die casting, or can be injection molded by plastic casting, so that the invention can be selected from raw materials. The orientation of the manufacturing method is also very liberal.
