Description

一种具有凸起的铜拉头 技术领域
本发明涉及拉链领域，尤其是指一种具有凸起的铜拉头。
背景技术
现有的铜拉头大多由拉头本体、弹片和拉片组成，其对弹片的质量要求较高，只要弹片一变形，整个铜拉头便宣告坏损，因此，铜拉头设计的重中之重便是避免弹片在使用中变形，而现有的铜拉头均难以有效解决这个问题。
中国发明专利一种具有锁定装置的拉链滑扣(授权公告号CN1165252C)，它包括：一设置在滑扣本体的上板的后部上的突伸件和一设置的棘爪孔；一设置在导柱的前表面内且带有一被啮合部的凹槽：一板簧，它呈倒U字形形状，并且包括一位于其一端的锁定棘爪和一位于其另一端且具有一啮合部的下垂件，一啮合用舌件设置在一中心基片内从而使其自所述中心基片上延伸出来而呈一种曲形状态；一设置在所述锁定棘爪附近并且与所述后突伸件自由地、可移动地啮合的钩合孔；与所述被啮合部相啮合的所述下垂件的所述啮合部：以及一带有拉襻的凸轮部的枢轴，它设置在所述后突伸件和所述啮合用舌件之间；所述拉链滑扣的特征在于：一接触部藉助一突伸件或一通孔形成在上板的前部上；所述啮合用舌件安装在上板上，从而使其能始终与所述接触部形成滑动接触。该专利中，拉动该拉片时，拉片会直接作用在板簧，长期使用，极易损坏。
中国发明专利一种用于拉链的带有锁定装置的拉头(授权公告号CN1268249C)，其公开了板状弹簧安装在本体上,其锁定爪从其一端弯曲并且弹簧部从另一端与锁定爪相同的方向弯曲。板状弹簧的弹簧部固定在本体的导柱的前端,使得弯曲部暴露在导柱。拉攀安装在本体与板状弹簧之间。一凸 轮被设置在拉攀的轴的底表面。当拉攀放置在本体的前侧时,在通孔的边与弯曲部之间形成一间隙,防止板状弹簧塑性变形。但是该专利也仅能解决拉攀放置在本体的前侧时防止板状弹簧塑性变形，而拉攀的使用过程中依然需要不断对板状弹簧施加作用力，依然会加快板状弹簧的耗损速度。
中国发明专利一种带有自动止动器的拉链滑块(授权公告号CN1301675C)，公开了其能够容纳一个在滑块的一个引导柱的前表面中的簧片的一个下垂件。在滑块的主体中，一个上片和一个下片通过引导柱互相连接，并且引导柱的前表面设有一个在一个垂直方向上连续开口的凹槽部分。通过弯曲位于上片的顶面上的自动止动机构的簧片的一端形成的下垂件接合并位于凹槽部分中，凹槽部分的底端设有一个向前突出的突出部分。突出部分位于下垂件的下面，以便保护下垂件的前端，并且突出部分的形状防止一个尖锐物体插在下垂件与突出部分之间，因此保护滑块，防止意外损坏。但是该专利也仅能避免尖锐物体插在下垂件与突出部分之间而保护滑块，而无法有效解决弹片在长期使用中变形的问题。

实施例一
参照图1、图2。一种具有凸起的铜拉头，包括拉头本体1、弹片2和拉片3，拉头本体1包括上翼板11、下翼板12以及连接该上翼板11前端与下翼板12前端的导柱13，拉片3由拉动部31和旋转部32组成，上翼板11的后部具有一凸块4，其中，
上翼板11的中部具有一向上凸出于该上翼板11上表面的凸层5；
弹片2的前侧21铆接于导柱13上，后侧22开设有第一通孔23，并通过该第一通孔23可活动地扣压于凸块4外侧；
旋转部32在竖直方向上位于弹片2与上翼板11之间、在水平方向上位于凸块4与凸层5之间，朝前拉动拉动部31时，该旋转部32能够抵触于凸层5的外侧壁上。
通过设置凸层5，使得拉片3转动时其旋转部32能够直接抵触于凸层5的外侧壁上，而不需要对弹片2施压，因此可以有效地防止弹片2塑性变形，提高拉链的使用寿命。
参照图1、图2。具体的，拉片3翻转至与上翼板11上表面相互平行时，旋转部32在竖直方向上分别与弹片2、上翼板11相抵触，在水平方向上分别与凸块4、凸层5相抵触。通过设置旋转部32在水平方向上与凸块4、凸层5相抵触，使得本拉头不使用时，拉片能够稳定地夹设在弹片与上翼板之间而不会轻易震动，一来提高了拉链整体的美观度，二来也提高了拉链的使用寿命。
参照图1、图2。具体的，凸块4呈7字型，其上端41朝后延伸穿过第一通孔23用于勾住弹片2以对其活动进行限位、下端42朝前呈斜向下的角度延伸至与上翼板11上端连接。通过设置7字型凸块的下端朝前呈斜向下的角度延伸，使得其与旋转部32相接触的一面具有斜度，并且两者之间形成的夹角为30～45°，从而给旋转部32的转动提供一个过渡的效果，进而使拉片的转动更加平滑。
参照图1、图2。具体的，凸层5的后侧壁51与顶壁52的连接处为一弧形面53。通过设置凸层的后侧壁与顶壁的连接处为一弧形面，使得拉片3转 动时，旋转部32是与平滑的弧角相抵触，由此能够避免出现旋转部转动时频繁接触尖锐的部位而受损的情况。
参照图1、图2。具体的，导柱13的前端开设有凹槽14，弹片2的前侧向下弯折并沉陷于凹槽14内与导柱13铆接在一起。
参照图1、图2。具体的，上翼板11后部与凸块4相对应的位置上开设有方孔15，弹片2的后端向下穿过方孔15并能够延伸至上翼板11与下翼板12之间。现有技术的上翼板均需冲压出两个方孔，本发明仅需冲压出一个，因此冲压模具成本将获得降低。
实施例二
参照图3、图4。一种具有凸起的防磨铜拉头，包括拉头本体6、弹片7和拉片8，拉头本体6包括上翼板61、下翼板62以及连接该上翼板61前端与下翼板62前端的导柱63，拉片8由拉动部81和旋转部82组成；上翼板61的后部具有一凸块9，上翼板61的中部具有一向上凸出于该上翼板61上表面的凸层10；弹片7的前侧71铆接于导柱63上，后侧72开设有第一通孔73，并通过该第一通孔73可活动地扣压于凸块9外侧；旋转部82在竖直方向上位于弹片7与上翼板61之间、在水平方向上位于凸块9与凸层10之间，朝前拉动拉动部81时，该旋转部82能够抵触于凸层10的外侧壁上，弹片7的中部开设有第二通孔74，并且该第二通孔74朝下正对凸层10。
通过设置凸层10，使得拉片8转动时其旋转部82能够直接抵触于凸层10的外侧壁上，而不需要对弹片7施压，因此可以有效地防止弹片7塑性变形，提高拉链的使用寿命。通过设置第二通孔74，使得当拉片8翻转至与上翼板61上表面相互平行时，凸层10原先作用于弹片7底部的部分会变为延伸至第二通孔74内，避免了凸层10与弹片7的直接接触，提高了拉链的使 用寿命。
参照图3、图4。具体的，拉片8翻转至与上翼板61上表面相互平行时，旋转部82在竖直方向上分别与弹片7、上翼板61相抵触，在水平方向上分别与凸块9、凸层10相抵触。通过设置旋转部82在水平方向上与凸块9、凸层10相抵触，使得本拉头不使用时，拉片能够稳定地夹设在弹片与上翼板之间而不会轻易震动，一来提高了拉链整体的美观度，二来也提高了拉链的使用寿命。
参照图3、图4。具体的，凸块9呈7字型，其上端91朝后延伸穿过第一通孔73用于勾住弹片7以对其活动进行限位、下端92朝前呈斜向下的角度延伸至与上翼板61上端连接。通过设置7字型凸块的下端朝前呈斜向下的角度延伸，使得其与旋转部82相接触的一面具有斜度，并且两者之间形成的夹角为30～45°，从而给旋转部82的转动提供一个过渡的效果，进而使拉片的转动更加平滑。
参照图3、图4。凸层10包括顶壁101与至少一个侧壁102，顶壁101的侧边通过弧形面103与侧壁的顶端平滑过渡连接；第二通孔74与顶壁101相适配，并且其内侧壁741与弧形面103上下相正对。本实施例中，凸层10及与其适配的第二通孔74呈均呈长方形。具体的为：凸层10包括方形顶壁101与四个侧壁102，方形顶壁101的四个侧边通过四个弧形面103与四个侧壁102的顶端一一平滑过渡连接；第二通孔74也呈方形，并且其四个内侧壁741与四个弧形面103一一上下相正对。通过设置第二通孔74的内侧壁741与弧形面103上下相正对，使得本实用新型在避免了凸层10与弹片7的直接接触的同时，还使得拉片8转动时，旋转部82是与平滑的弧角相抵触，由此能够避免出现旋转部转动时频繁接触尖锐的部位而受损的情况。此外，也可 设置凸层及与其适配的第二通孔呈三角形、半圆形、正方形、多边形等，在此便不再赘述。
参照图3、图4。具体的，导柱63的前端开设有凹槽64，弹片7的前侧向下弯折并沉陷于凹槽64内与导柱63铆接在一起。
参照图3、图4。具体的，上翼板61后部与凸块9相对应的位置上开设有方孔65，弹片7的后端向下穿过方孔65并能够延伸至上翼板61与下翼板62之间。现有技术的上翼板均需冲压出两个方孔，本实用新型仅需冲压出一个，因此冲压模具成本将获得降低。
上述仅为本发明的具体实施方式，但本发明的设计构思并不局限于此，凡利用此构思对本发明进行非实质性的改动，均应属于侵犯本发明保护范围的行为。
