Description

一种拉头及一种拉链
本申请要求于2018年06月15日提交中国专利局、申请号为201810620521.5、发明名称为“一种拉头及一种拉链”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及服饰用品技术领域，更具体地说，涉及一种拉头，还涉及一种包括上述拉头的拉链。
背景技术
拉链是用于服装上的一种辅料，拉链又是由拉头、布带、链牙、方块插销等基本组成，而拉头不仅影响拉链开合的功能性作用，还影响外观、使用便捷性等，因此拉头的结构设计影响至关重要。常见的拉头分为很多种，例如普通拉头、导轨式拉头、火车式拉头以及弹簧式拉头。
弹簧回弹式拉头的基本组成分为拉体01、保险、拉片02，图1为现有技术中拉头的示意图，弹簧头拉片02如图1状态时是处“锁住”状态-即拉头无法轻易上下移动，拉片02处于竖立状态(即拉体01与拉片02成直角、图二)此时即“解锁状态”，图2为现有技术中拉链的解锁状态示意图，即拉头可以顺畅进行滑动。但是目前普遍存在已经完成拉链合链后，拉头处于图二的状态且不会主动倾倒，这种情况会使拉链失锁，拉链失去锁合力后衣服会滑落，给运动带来了很大的不便，体验感不好。目前市面上这种弹簧拉头的改进只在拉片02上进行改动，改进的方式是在拉片02上添加回型的挡块，当拉片02在快拉到与拉体01成直角状态的时候挡块会与拉体01的上底板接触从而回弹，缺点是这种设计在拉片02正好与拉体01成直角的时候会卡在那里不会弹回来。
发明内容
有鉴于此，本发明的第一个目的在于提供一种拉头，以解决拉链在合链后、拉头无法自动回弹进而导致拉链失锁的问题，本发明的第二个目的 是提供一种包括拉头的拉锁。
为了达到上述第一个目的，本发明提供如下技术方案：
一种拉头，包括拉片、拉体和保险，所述拉体上设有上底板和下底板，所述上底板上设有对应设置的后铆体组和前铆体组，所述后铆体组和所述前铆体组形成安装腔，所述拉片包括水平部和与所述水平部连接的侧柱，所述拉片的水平部设于所述安装腔内且可沿所述水平部的自身轴线旋转，所述保险分别与所述拉体和所述拉片连接以能够实现锁止，所述拉片旋转至与所述前铆体组接触时，所述前铆体组与所述拉片的侧柱接触以阻隔所述拉片的翻转。
优选地，所述水平部的内端面设有第一凸起部，所述第一凸起部的上表面至所述上底板间的距离大于所述安装腔内所述前铆体组的上端面至所述上底板间的距离。
优选地，所述保险靠近所述前铆体组的一侧设有用于阻隔所述拉片旋转的阻挡块，所述水平部上设有与所述阻挡块配合的第二凸起部。
优选地，所述阻挡块沿所述保险的轴向方向设置。
优选地，所述阻挡块与所述保险一体式设置。
本发明提供的拉头，包括拉片、拉体和保险，所述拉体上设有上底板和下底板，所述上底板上设有对应设置的后铆体组和前铆体组，所述后铆体组和所述前铆体组形成安装腔，所述拉片包括水平部和与所述水平部连接的侧柱，所述拉片的水平部设于所述安装腔内且可沿所述水平部的自身轴线旋转，所述保险分别与所述拉体和所述拉片连接以能够实现锁止，所述拉片旋转至与所述前铆体组接触时，所述前铆体组与所述拉片的侧柱接触以阻隔所述拉片的翻转。
应用本发明提供的拉头，拉片旋转过后铆体组旋转至与前铆体组接触时，前铆体组与拉片的侧柱接触，前铆体组通过阻挡侧柱进而阻隔拉片的旋转路径，且由于前铆体组对旋转的拉片施力，使得拉片以水平部为旋转轴线回弹至拉头后端，保险下锁从而锁住拉链，使得拉链固定在相应的位置，实现拉片的回弹。
为了达到上述第二个目的，本发明还提供了一种拉链，该拉链包括布 带、链牙和方块插销，该拉链还包括上述任一种拉头，由于上述的拉头具有上述技术效果，具有该拉头的拉链也应具有相应的技术效果。
附图说明

具体实施方式
本发明实施例公开了一种拉头，以解决拉链在合链后、拉头无法自动回弹进而导致拉链失锁的问题。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图3-图8，图3为本发明实施例中的拉头的结构示意图；图4为本发明实施例中的拉片回弹结构示意图；图5为本发明实施例中的拉片的结构示意图；图6为本发明实施例中的保险的结构示意图；图7为本发明实施例中的第二凸起部的结构示意图；图8为本发明实施例中的保险的安装剖视图。
在一种具体的实施方式中，本发明提供的拉头，包括拉片2、拉体1和保险9，拉体1上设有上底板5和下底板6，上底板5上设有对应设置的后铆体组4和前铆体组3，后铆体组4和前铆体组3形成安装腔，拉片2包括水平部和与水平部连接的侧柱，拉片2的水平部设于安装腔内且可沿水平部的自身轴线旋转，保险9分别与拉体1和拉片2连接以能够实现锁止，拉片2旋转至与前铆体组3接触时，前铆体组3与拉片2的侧柱接触以阻隔拉片2的翻转。
拉体1与上底板5和下底板6的连接方式可参考现有技术，上底板5上设有后铆体组4和前铆体组3，一般的，后铆体组4包括两个左铆体，同样的，前铆体组3包括两个右铆体，两个左铆体和两个右铆体对称设置，后铆体组4和前铆体组3形成安装腔，拉片2设置在安装腔中，其中，拉片2的水平部设置在安装腔中且可沿水平部轴线旋转，以实现拉片2的翻转，保险9与拉体1和拉片2的连接方式可参考现有技术，具体的，右铆体沿安装腔的轴向长度与拉片2的侧柱位置有关，其中，当拉片2旋转通过后铆体组4而旋转至前铆体组3时，拉片2的侧柱与右铆体接触，阻隔拉片2进行翻转。
在一种实施例中，拉头安装在衣服上，在不使用的情况下拉片2会倾倒在拉体1的后端侧，当使用拉片2时，需要将拉片2提起垂直于拉体1，当拉片2在拉倒与拉体1上底板5即将呈直角时，拉片2的侧柱与前铆体组3接触，从而使得拉片2不能在超过直角转动，在拉片2接近90度时能够倒倾回拉头后端，使得保险9重新下锁从而锁住拉链。
应用本发明提供的拉头，拉片2旋转过后铆体组4旋转至与前铆体组3接触时，前铆体组3与拉片2的侧柱接触，前铆体组3通过阻挡侧柱进而阻隔拉片2的旋转路径，且由于前铆体组3对旋转的拉片2施力，使得拉片2以水平部为旋转轴线回弹至拉头后端，保险9下锁从而锁住拉链，使得拉链固定在相应的位置，实现拉片2的回弹。
在一种实施例中，水平部的内端面设有第一凸起部7，第一凸起部7的上表面至上底板5间的距离大于安装腔内前铆体组3的上端面至上底板5间的距离。可以理解的是，第一凸起部7的上表面和安装腔内前铆体组3的上端面配合，第一凸起部7的上表面至上底板5间的距离大于前铆体组3的上端面至上底板5间的距离，相较于后铆体组4，可通过增加安装腔内前铆体组3的上端面部的厚度达到上述目的，其中，后铆体组4和前铆体组3形成的安装腔优选为矩形腔，当然，在其他实施例中，也可以设置为圆形腔，可根据实际需要进行设置，均在本发明的保护范围内，可以理解的是，加厚后的前铆体组3与上底板5间隙距离需大于拉片2的厚度，以保证拉片2可植入，在一种实施例中，通过在拉片2的两侧增加第一凸起部7，第一凸起部7的大小和位置与上底板5上铆体的位置相对应，当拉头安装在衣服上时拉动拉片2至一定位置后，拉片2在快旋转至直角位置时，第一凸起部7与安装腔内前铆体组3的上表面碰触，无法继续旋转，拉片2被弹回至拉头后端，同时保险9也会下锁从而锁住拉链，使得拉链固定在相应的位置，实现拉片2的回弹。
具体的，保险9靠近前铆体组3的一侧设有用于阻隔拉片2旋转的阻挡块10，水平部上设有与阻挡块10配合的第二凸起部8。阻挡块10可设置在保险9沿轴线的内侧下方，当拉片2竖起至与拉体1成一定角度(不超过90度)，阻挡块10与拉片2水平部中间的第二凸起部8接触，从而阻止拉片2向拉体1前端倒倾，使其倒倾至拉体1后端，保险9下锁从而锁住拉链实现衣服的固定。优选地，阻挡块10沿保险9的轴向方向设置，第二凸起部8的具体结构可根据实际需要进行设置，如凸起块等，凸起块可与拉片2一体式设置或者通过焊接等方式进行固定，可根据实际需要进行设置。更为优选的，阻挡块10与保险9一体式设置，以便于加工。
基于上述实施例中提供的拉头，本发明还提供了一种拉锁，包括布带、链牙和方块插销，该拉锁还包括上述实施例中任意一种拉头，由于该拉链采用了上述实施例中的拉头，所以该拉链的有益效果请参考上述实施例。
最后，还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定 要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
