采用上述技术方案，第二拉头的底部设有插入部，在第一拉头和第二拉头相互靠近过程中，第二拉头底部的插入部作用锁定块并使得锁定板绕铰接处克服驱动件的力旋转进而使得插入部卡入锁定组件中，完成第一拉头和第二拉头之间的锁定。
通过在拉链位于第二拉头远离第一拉头的一侧的端部设置解锁机构，将第一拉头和第二拉头的锁定联合体拉动到解锁机构处，解锁机构上的解锁块插入锁定块的上端并使得锁定块跟随锁定板绕转轴旋转并解除对插入部的限位，此时即可完成解锁。
在插入部上设置向第一拉头的尾端方向延伸的第一限位台阶，在锁定板组件的锁定块上设置第二限位台阶，当第一限位台阶与第二限位台阶相对设置时候(即插入部在插入部容纳区内靠近锁定块或者与锁定块相贴时)，插入部上的第一限位台阶是能够阻止锁定板旋转进而阻止解锁块进行开锁，因此即便了解到要采用将第一拉头和第二拉头的锁定结合体移动到靠近隐藏在拉链内侧的解锁块处才能进行解锁，但是具体的解锁方法不对也仍然无法开锁，进一步提高解锁的隐蔽性。
采用本发明中所保护的解锁方法，拉动第一拉头进而带动与第一拉头锁定的第二拉头移动到解锁块处并触碰解锁块，然后拉动第一拉头远离第二拉头即可实现双头拉链机构的解锁。全程只需要拉动同一个拉头，解锁方便快捷。

具体实施方式
下面结合附图和具体实施例，对本发明进行说明。
如图1-8所示，一种双头拉链机构，包括拉链1、设在拉链1上的第一拉头2、设在拉链1上的第二拉头3以及解锁结构25。
第一拉头2的底部设有锁定组件，锁定组件包括设在第一拉头2底部 的锁定罩4、铰接在锁定罩4中的锁定板5、设在锁定板5靠近第二拉头3一端的锁定块6以及使锁定块6保持在锁定位的驱动件，锁定板5通过转轴7与锁定罩4铰接。锁定罩4靠近第二拉头3一端设置有第一插孔8，锁定块6设置在第一插孔8处，驱动件作用锁定板5并使锁定块6封挡在第一插孔8处。
如图7所示，锁定板5包括第一板体9、设在第一板体9靠近第一插孔8一端的两个间隔设置的第二板体10，两个第二板体10之间形成插入部容纳区11，锁定块6设置在第二板体10远离第一板体9一端并连接两第二板体10的端部。
第二拉头3的底部设有插入部12，插入部12设在第二拉头3靠近第一拉头2一端，插入部12包括设在第二拉头3底部的第一插接板13以及设在第一插接板13底部的第二插接板14，第一插接板13、第二插接板14以及第二拉头3的底板形成工字型件，第一插孔8上方设有开口槽，
开口槽的两侧分别形成用于卡入工字型件两侧的卡板15。在第一拉头2和第二拉头3相互靠近过程中，插入部12作用锁定块6并使得锁定板5绕铰接处克服驱动件的力旋转进而使得插入部12通过第一插孔8卡入锁定组件中。
解锁结构设在拉链1位于第二拉头3远离第一拉头2的一侧的端部，解锁结构25包括固定块16和向拉链1延伸方向一侧凸出设置的解锁块17，固定块16设置在拉链1的端部，解锁块17设置在固定块16的侧面，解锁块17为解锁板，解锁板的伸出端的底部设有向伸出端喔并向上倾斜设置的驱动壁18，解锁板插入锁定块6的上端并使得锁定块6跟随锁定板5绕转轴7旋转并解除对插入部12的限位。
另外，为了进一步增加锁定以及解锁的可靠性，锁定块6靠近第二拉头3一端的上部设置有用于与解锁块17以及插入部12相互作用的导向圆弧19。
驱动件包括两种实施方式：
实施例一：
如图5、6所示，驱动件为设于锁定板5的上方的用于吸取锁定板5的磁铁20，磁铁20固定在第一拉头2的底部，磁铁20位于转轴7靠近锁定块6一侧。通过磁铁20的吸附力，使得锁定块6封挡在第一插孔8处。
实施例二：
如图8所示，驱动件为设在锁定罩4中的弹性件，弹性件为压缩弹簧21，压缩弹簧21设在转轴7靠近锁定块6一侧，压缩弹簧21设置在锁定罩4的底部内壁与锁定板5之间，锁定罩4的底部设有安装柱22，压缩弹簧21套设在安装柱22上，锁定板5上对应安装柱22的位置设置有避让孔。另外，弹性件可以设置成扭簧，扭簧套设在转轴7上。
采用上述技术方案，第二拉头3的底部设有插入部12，在第一拉头2和第二拉头3相互靠近过程中，第二拉头3底部的插入部12作用锁定块6并使得锁定板5绕铰接处克服驱动件的力旋转进而使得锁定块6卡置插入部12，完成第一拉头2和第二拉头3之间的锁定。
通过在拉链1位于第二拉头3远离第一拉头2的一侧的端部设置解锁结构25，将第一拉头2和第二拉头3的锁定联合体拉动到解锁结构25处，解锁结构25上的解锁块17插入锁定块6的上端并使得锁定块6跟随锁定板5绕转轴7旋转并解除对插入部12的限位，此时即可完成解锁。
另外，在上述各方案的基础上，如图9-18所示，对技术方案进行了进一步的改进，具体如下：
第一项改进：
如图9-13以及图18所示，对第二拉头3的插入部12进行了改进，第二插接板14的尾端伸出到第一插接板13的尾端外侧并形成第一限位台阶30，第一限位台阶30的台阶面朝向第二拉头3一侧。锁定块6位于插入部容纳区11的一端设置有第二限位台阶31，第二限位台阶31的台阶 面朝向远离第一拉头2一侧，插入部容纳区11在拉链1延伸方向上的长度尺寸大于插入部12的长度尺寸，插入部12在插入部容纳区11中靠近锁定块6时，第一限位台阶30的台阶面与第二限位台阶31的台阶面相对设置并阻止锁定板5旋转。
采用该项改进的技术方案，在插入部12上设置向第一拉头2的尾端方向延伸的第一限位台阶30，在锁定板5组件的锁定块6上设置第二限位台阶31，当第一限位台阶30与第二限位台阶31相对设置时候(即插入部12在插入部容纳区11内靠近锁定块6或者与锁定块6相贴时)，插入部12上的第一限位台阶30是能够阻止锁定板5旋转进而阻止解锁块17进行开锁，因此即便了解到要采用将第一拉头2和第二拉头3的锁定结合体移动到靠近隐藏在拉链1内侧的解锁块17处才能进行解锁，但是具体的解锁方法不对也仍然无法开锁，进一步提高解锁的隐蔽性。
上述解锁方法为，将相互锁定后的第一拉头2和第二拉头3移动到解锁块17处，解锁块17作用锁定块6并使锁定块6绕转轴7旋转进而从第一插孔8处移开，在解锁块17作用锁定块6时，插入部12在插入部容纳区11中远离锁定块6进而使得插入部12上的第一限位台阶30远离锁定块6上的第二限位台阶31；待锁定块6移开第一插孔8处后，拉动第一拉头2远离第二拉头3进而实现双头拉链机构的解锁。
更加直观的解锁方法为：拉动第一拉头2进而带动与第一拉头2锁定的第二拉头3移动到解锁块17处并触碰解锁块17，然后拉动第一拉头2远离第二拉头3即可实现双头拉链机构的解锁。全程只需要拉动同一个拉头，解锁方便快捷。
第二项改进：
如图9所示，解锁机构设置在拉链1的内侧，解锁机构还包括固定板32，固定板32设置在靠近拉链1端部的位置，具体为固定板32通过缝线固定在箱包内侧靠近拉链1端部的位置，固定板32靠近拉链1的延伸方向一侧设置有避让第二拉头3的凹槽33，凹槽33靠近拉链1延伸方向一 端设置解锁块17，采用该种解锁机构，解锁机构不显露在拉链1的外侧，提高隐蔽性。
第三项改进：
如图11、16所示，锁定罩4采用分体式的结构，锁定罩4包括第一罩体34和第二罩体35，第一罩体34固设在第一拉头2上远离第二拉头3的一端，第二罩体35包括内罩体单元36和外罩体单元37，内罩体单元36插入到第一罩体34中，外罩体单元37伸出到第一罩体34的外侧并设置有第一插孔8，锁定板5铰接在第二罩体35内，驱动件设置在第二罩体35内。第一罩体34的内部设置有卡凸38，卡凸38上设置有引导斜壁39，内罩体单元36上对应于卡凸38设置有卡槽40，内罩体单元36远离外罩体单元37的端部设置有撬口41，通过撬口41撬动内罩体单元36进而使得卡凸38从卡槽40中移出。
锁定罩4采用分体式的结构，可以对第二罩体35进行方便快捷的拆卸，方便对与之连接的锁定板5、锁定块6等部件进行更换或者维修。
第四项改进：
如图15、17所示，双头拉链机构还包括上锁组件，上锁组件设置在锁定板5远离第二拉头3一侧且位于锁定罩4的内壁与锁定板5之间，上锁组件设置在转轴7靠近锁定块6的一侧，上锁组件包括能够横向移动的锁栓42，锁栓42的两端分别伸出到锁定罩4的外侧，锁栓42包括锁定段43和一解锁段44，锁定段43的外壁到锁定板5的距离小于解锁段44的外壁到锁定板5的距离，锁定段43横向移动到锁定板5与锁定罩4的内壁之间时，锁定段43阻止锁定板5克服驱动件的力绕转轴7移动。
采用该种上锁机构，能够透过箱包的外表面控制内部的锁栓42进行横向移动，当解锁段44移动到锁定板5与锁定罩4的内壁之间时，锁栓42不会对锁定板5的旋转进行干涉，当锁定段43移动到锁定板5与锁定罩4的内壁之间时，能够阻止锁定板5旋转，进而阻止锁定块6从第一插孔8处移开。
最后需要说明的是，如图14、15所示，驱动件还可以采用在转轴7远离锁定块6一侧设置压缩弹簧21或者弹性体45的形式，其也能起到驱动锁定块6封挡第一插孔的作用。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改、组合和变化。凡在本发明的精神和原理之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
