Description

发明名称：一种拉链链齿以及具有该拉链链齿的拉链
技术领域
[0001] 本实用新型涉及拉链技术领域， 特别是涉及一种具有多个齿头的拉链链齿。
背景技术
[0002] 现有技术的拉链结构普遍采用一种 P型拉链， 即在拉链链齿的前端边缘处设置 斜角齿头， 并在与其对应的另一面设置一个对应的齿槽， 拉链的左右链齿由于 拉头的移动， 带动斜角齿头的导出导入以完成拉链的幵合动作， 为了最大程度 的提高齿头与对接的齿槽的扣合力， 则尽可能增大齿头的尺寸， 使齿头的基座 尺寸与拉链的厚度基本一致， 但是， 这种设计使链齿与链齿之间的扣合只形成 一个咬合点， 拉链拉合后只形成一条扣合线， 当拉链受到左右方向较大外力的 撕扯， 尤其是被尖锐的硬物正面撞击吋， 带多面斜口的齿头的咬合点就会较容 易顺着斜口的方向连续脱幵， 最终使拉链爆幵， 降低了拉链的可靠性。
[0003] 另外， 现有技术的拉链链齿的上下表面多为对称的平面设计， 拉链的上下表面 与拉头的内腔壁的接触面积较大， 当拉头拉动链齿咬合的过程中， 拉链的上下 表面与拉头的内腔壁易产生摩擦， 由于无数次的拉合， 会在链齿表面形成划痕 ， 影响拉链的美观， 也会对拉头造成一定程度的磨损。

[0005] 为解决上述技术问题， 本实用新型所采用的技术方案是：
[0006] 一种拉链链齿， 包括链齿本体， 所述链齿本体包括第一啮合面和第二啮合面， 其特征在于所述第一啮合面上设置有至少两个齿头， 所述第二啮合面上设置有 分别与第一啮合面上的齿头相对应配合的至少两个齿槽； 所述链齿本体上还设 置有贯穿第一啮合面及第二啮合面的幵口槽。

本发明的实施方式
[0023] 下面结合附图对本实用新型做以下详细说明。
[0024] 如图 1所示， 本实用新型一个实施例提供的拉链链齿， 包括链齿本体 1， 所述链 齿本体 1包括第一啮合面 11和第二啮合面 12， 其特征在于所述第一啮合面 11上设 置有第一齿头 21及第二齿头 22， 所述第二啮合面 12上设置有分别与第一齿头 21 及第二齿头 22相对应配合的第一齿槽 23及第二齿槽 24; 所述链齿本体 1上还设置 有贯穿第一啮合面 11及第二啮合面 12的幵口槽 3。
[0025] 所述第一啮合面 11平行于所述第二啮合面 12且与第二啮合面 12形状相同； 所述 第一啮合面 11由弧边 13与弦边 14相连接而形成， 所述第二啮合面 12由弧边 15与 弦边 16相连接而形成， 所述弧边 13及弧边 15在所述幵口槽 3处断幵。 由所述弧边 13及弧边 15在垂直于第一啮合面 11与第二啮合面 12的方向上形成一个圆弧形侧 壁， 所述圆弧形侧壁与拉头内腔表面的接触面积较小， 减少链齿与拉头间的摩 擦， 提高拉链的顺滑度。
[0026] 所述弧边 13与弦边 14的连接具有过渡倒角， 所述弧边 15与弦边 16的连接具有过 渡倒角， 则减少拉头内腔侧壁对拉链链齿的磨损。
[0027] 所述第一齿头 21与第二齿头 22的尺寸相同， 所述第一齿槽 23与第二齿槽 24的尺 寸相同， 能够保证拉链在拉合过程中第一齿头 21和第一齿槽 23、 第二齿头 22和 第二齿槽 24啮合动作的一致。
[0028] 如图 2所示， 所述第一齿头 21及第二齿头 22为凸起于齿身一个侧面的梯形体， 优选地， 梯形体为圆角梯形体。 与现有技术的斜角齿头相比， 梯形齿头的啮合 更加稳固， 不易沿斜角的方向滑出；
[0029] 另外， 第一齿头 21及第二齿头 22分别设置， 在使用过程中， 第一齿头 21及第二 齿头 22的相互影响较小， 即使因为过大的外力而可能使其中的一个齿头脱离啮 合， 也不会导致另外一个齿头也同样脱离啮合。
[0030] 如图 3所示， 所述第一齿头 21及第二齿头 22与所述第一啮合面 11的弧线 13及弦 线 14之间具有间隔， 与弧线 13的距离为 a， 与弦线 14的距离为 b， 则使得齿头与齿 槽的啮合位置未在链齿的边缘处， 当拉链受到左右方向的拉扯吋， 与 P型链齿相 比， 本实用新型的链齿的啮合更稳固。
[0031] 所述第一齿头 21及第二齿头 22的长度 c小于拉链的厚度 d， 优选的， 齿头的长度 c小于拉链的厚度 d的 1/2， 应当意识到， 作为替换的方案， 可以在拉链的厚度方 向上设置多个齿头， 通过多点啮合增大拉链链齿之间的啮合强度， 提高拉链的 可靠性。
[0032] 所述幵口槽 3的截面为 "Ω"形、 "C"形或弧度大于 180ο的弧形。
[0033] 所述链齿固定在拉链的两个链带上， 两链带上的链齿对接连接， 则第一齿头 21 与对接的链齿的第一齿槽相互啮合， 第二齿头 22与对接的链齿的第二齿槽相互 啮合 （参考图 4) 。 链齿上采用两个齿头， 使得拉链拉合后形成了一个框架式的 啮合结构， 拉链能够承受较大的外力而不易爆幵。
[0034] 如图 5所示， 本实用新型实施例还提供了一种拉链， 该拉链采用如上所述的拉 链链齿。
[0035] 本实施例中， 多个齿头采用在连续的冲压模具下成型。
[0036] 上述实施例是以拉链链齿上具有两个齿头为例进行的详细说明， 可以作为本实 用新型的一种优选方式， 但本实用新型的实施方式并不为上述实施例所限定。
