Description

一种拉链齿及拉链 技术领域
本申请涉及拉链技术领域，特别涉及一种拉链齿及拉链。
 背景技术
随着近年来拉链应用的越来越广泛，各种结构设计的拉链层出不穷，其中塑钢拉链因其在外观和结构设计上相较于金属拉链和尼龙拉链具有更大的改变空间，而且塑钢拉链拥有材料成本较低的优势，因此塑钢拉链在拉链应用中逐渐成为流行的趋势。但是现有的塑钢拉链整体摩擦阻力大，导致拉链使用时的顺滑度较差。
 技术问题
本申请实施例提供一种拉链齿及拉链，解决了现有的塑钢拉链使用时顺滑度较差的问题。
 技术解决方案
第一方面，提供了一种拉链齿，所述拉链齿沿齿宽方向的至少一侧表面为弧面，所述弧面沿所述拉链齿的齿厚方向弯曲。
根据本申请实施例提供的拉链齿，将拉链齿沿齿宽方向的至少一侧表面设置为弧面，且弧面沿所述拉链齿的齿厚方向弯曲，这样可以使拉链齿接触拉头内腔的表面为弧面，减少摩擦面积，使拉链使用时顺滑度更好。
在一种可能的设计中，所述拉链齿的最大厚度小于所述拉链齿宽度的60%。
在一种可能的设计中，所述弧面与所述拉链齿沿齿厚方向的至少一侧表面的连接处形成有第一台阶。
在一种可能的设计中，沿所述拉链齿齿高方向，位于所述拉链齿的齿根端的端面与所述弧面的连接处形成有第二台阶。
在一种可能的设计中，所述拉链齿的齿根处具有沿齿厚方向贯穿所述拉链齿的布带咬合槽；
所述第一台阶具有垂直于所述拉链齿齿宽方向的第一台阶面，所述第二台阶具有垂直于所述拉链齿齿宽方向的第二台阶面；
所述布带咬合槽正面分别与第一台阶面和所述第二台阶面不相切。
在一种可能的设计中，所述拉链齿包括齿身以及位于所述齿身上的齿头，所述齿身沿齿高方向的最大高度大于所述布带咬合槽沿齿高方向的最大槽深度。
在一种可能的设计中，所述拉链齿为塑钢材料。
第二方面，提供了一种拉链，包括两片链带，所述链带上设有一列如上述的拉链齿；
锁紧件，所述锁紧件分别设于所述链带两端；
拉头，所述拉头分别夹持两片所述链带上的所述拉链齿，通过拉襻滑行使两片所述链带上的所述拉链齿互相啮合或分开。
在一种可能的设计中，所述链带上的一列所述拉链齿沿齿厚方向错位交叠排列。
 有益效果
本发明实现的有益效果是：将拉链齿沿齿宽方向的至少一侧表面设置为沿所述拉链齿的齿厚方向弯曲的弧面，这样可以使拉链在使用时拉链齿与拉头内腔接触的面积变小，有效减少摩擦，提高了拉链使用的顺滑度；此外，在拉链齿上设置第一台阶可以使弧面在拉链齿的齿厚方向上投影的长度小于拉链齿的齿厚，同时台阶又能在视觉上突出弧面，这样就可以在视觉上减小拉链齿的齿厚，形成拉链齿细长的外观形状；在拉链齿上设置第二台阶可以使沿拉链齿齿高方向，位于拉链齿的齿根端的端面外形更加美观；此外，对拉链齿厚度和宽度的设置使得拉链齿形成细长的外观，不仅外形美观，还可以减小拉链齿使用的摩擦阻力；此外，对拉链齿齿身和布带咬合槽的位置距离的设置使得拉链齿具有足够的咬合体积，布带咬合能力更好。

 本发明的实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，在本申请的描述中，“至少一个”的含义是一个或一个以上，除非另有明确具体的限定。
还需说明的是，本申请实施例中以同一附图标记表示同一组成部分或同一零部件，对于本申请实施例中相同的零部件，图中可能仅以其中一个零件或部件为例标注了附图标记，应理解的是，对于其他相同的零件或部件，附图标记同样适用。
本申请实施例提供一种拉链齿及拉链，解决了现有的塑钢拉链使用时顺滑度较差的问题。
如图1所示，本申请实施例提供的拉链齿沿齿宽方向的至少一侧表面为弧面10，弧面10沿拉链齿的齿厚方向弯曲。
根据本申请实施例提供的拉链齿，将拉链齿沿齿宽方向的至少一侧表面设置为弧面10，且弧面10沿所述拉链齿的齿厚方向弯曲，这样可以使拉链齿接触拉头内腔的表面为弧面10，减少摩擦面积，使拉链使用时顺滑度更好。
可选的，拉链齿为塑钢材料。采用塑钢材料可以降低拉链齿的材料成本，而且本申请实施例的拉链齿结构采用塑钢材料更容易制造，制造难度小。
如图1所示，弧面10与拉链齿沿齿厚方向的至少一侧表面的连接处形成有第一台阶30。
通过以上设置，由于第一台阶30在拉链齿齿厚方向上具有一定的长度，因此弧面10在拉链齿齿厚方向上投影的长度小于拉链齿的齿厚，而且第一台阶30的设置会在视觉上将弧面10突出，这样可以在视觉上减小拉链齿的齿厚，使拉链齿具有细长的外观，更加美观。
需要说明的是，拉链齿的齿厚方向与拉链齿的齿宽方向垂直，拉链齿的齿高方向分别与拉链齿的齿厚方向和拉链齿的齿宽方向均垂直。
如图1所示，沿拉链齿齿高方向，位于拉链齿的齿根11端的端面与弧面10的连接处形成有第二台阶40。
通过以上设置，第二台阶40的设置使得沿拉链齿齿高方向，位于拉链齿的齿根11端的端面在视觉上更加美观。
如图1-3所示，所述拉链齿的齿根11处具有沿齿厚方向贯穿所述拉链齿的布带咬合槽20；第一台阶30具有垂直于拉链齿齿宽方向的第一台阶面31，第二台阶40具有垂直于拉链齿齿宽方向的第二台阶面41；布带咬合槽20正面分别与第一台阶面31和第二台阶面41不相切。
以上设置中，第一台阶面31和第二台阶面41均为水平面，布带咬合槽20正面分别与第一台阶面31和第二台阶面41不相切，可以避免布带咬合槽20的中心线外露而导致的拉链齿强力不足的隐患。
图2为拉链齿沿齿厚方向的截面图，当布带咬合槽20沿齿厚方向的截面为弧形时，且第一台阶面31和第二台阶面41位于同一平面，图2中的S1指弧面10垂直于拉链齿齿宽方向的切平面，S2指第一台阶30的第一台阶面31，图2中的L1指弧面10垂直于拉链齿齿宽方向的切平面与布带咬合槽20截面所在圆的圆心之间的距离，L2指第一台阶面31与布带咬合槽20截面所在圆的圆心之间的距离，即L1大于L2。
如图2-3所示，拉链齿的最大厚度小于拉链齿宽度的60%。通过以上设置，使得拉链齿形成细长的外观，不仅外形美观，还可以减小拉链齿使用的摩擦阻力。
图3为拉链齿具有弧面的一侧表面的示意图，图3中的L4指拉链齿的最大厚度，图2中的L3指拉链齿的宽度，即L4小于L3的60%。
如图2所示，拉链齿包括齿身100以及位于齿身100上的齿头200，齿身100沿齿高方向的最大高度大于布带咬合槽20沿齿高方向的最大槽深度。
通过以上设置，可以确保齿身100有足够大的体积，拉链齿有足够的咬合力咬合布带，也能避免布带咬合槽20的中心线外露而导致的拉链齿强力不足的隐患。
图2中的L5指布带咬合槽20截面所在圆的圆半径，即L2大于L5。
图2和图3中的L6指齿身100沿齿高方向的最大高度，图2中的L7指布带咬合槽20沿齿高方向的最大槽深度，即布带咬合槽20截面所在圆的圆直径，即L6大于L7。
如图4所示，本申请实施例提供的拉链包括两片链带，链带上设有一列如上述的拉链齿；锁紧件，锁紧件分别设于链带两端；拉头，拉头分别夹持两片链带上的拉链齿，通过拉襻滑行使两片链带上的拉链齿互相啮合或分开。
根据本申请实施例的拉链，具有上述拉链齿可以使拉链使用时顺滑度更好。
作为一种可选的实施方式，如图6所示，链带上的一列拉链齿沿齿厚方向不错位交叠排列。这样可以确保拉链齿沿齿宽方向的两侧齿头彼此的接触面积足够大，使得拉链齿沿齿宽方向的两侧齿头的结合力变强，拉链可以顺利使用。
作为另一种可选的实施方式，如图5所示，链带上的一列拉链齿沿齿厚方向错位交叠排列。
本申请的拉链齿在沿齿宽方向的两部分拉链齿为错位设置，由于拉链齿为细长型，因此拉链齿在排列时，为确保拉链齿的齿头能有效的齿合两部分拉链齿，并且防止两部分拉链齿因齿宽较窄，容易在上下弯折时相互错开而爆链，因此采用错位交叠的排列方式对拉链齿进行排列，这样在拉链使用时相邻的两个拉链齿就不会出现相互错开而爆链的情况了。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
