依借上述技术方案，本发明所提供的按键结构装配安装到键盘上之后，在使用过程中，所述键帽受到使用者向下的压力，压动所述主轴向下运动，而所述端台随之向下运动过程中改变了端起所述端点凸台的状态，所述副轴不受所述端点的支撑后在重力作用下或者在弹性器件弹压之下向下运动压迫所述导电膜的连接点，完成导通的任务，此时，所述主轴继续向下运行剩余空行程，之后在主弹簧的作用下进行复位，而所述主轴的端台到达所述端点凸台下方之时将所述端点凸台抬起推动所述副轴复位，所述副轴的导通点离开所述导电膜断开连通，使所述端台恢复为端起所述端点凸台状态。本技术方案具有以下有益效果，具有机械键盘手感，所述主轴空行程带来好的手感；所述主轴下压的同时所述副轴被放松即刻导通导电膜，而所述主轴仍然继续下压，灵敏度大大提高；本技术方案所使用的元件采用塑胶材料，相对于其他机械键盘的金属元件按钮具有成本低的优势，同时，现有技术中的机械键盘通常采用 PCB 板，将按键元件焊接到 PCB 板上，所以无法使用价廉的 PET 导电膜，而本发明的技术方案可以轻松使用价廉的 PET 导电膜，致使成本大幅降低。 依借本发明所提供的按键结构，上述组装方法也能大幅降低组装键盘时所产生的人工成本，减少了在 PCB 板上的焊接环节，配件组装方便快捷。

 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一，
参照图 1 和图 2 所示，本实施例提供一种按键结构， 包括键帽 10 ，主轴 20 ，上盖 30 ，主弹簧 90 ，下盖 80 ，导电膜 70 ，副轴 50 ，其中，所述下盖 80 具有支撑板 81 ，所述支撑板 81 上方铺设所述导电膜 70 ，所述下盖 80 的支撑板 81 和导电膜 70 以及上盖 30 均设有可供所述主轴 20 穿过的通孔，所述上盖 30 的通孔只可供所述主轴 20 上半部穿过，所述主弹簧 90 下端设于所述下盖 80 内，上部套装于所述主轴 20 内，所述主轴 20 上方与所述键帽 10 下表面相连接，所述上盖 30 所设通孔的相对另一端下方设有副轴 50 ，所述副轴 50 正对其下方的导电膜 70 的连接点，所述连接点是受到压力时使导电膜 70 中的电路产生连接发出电信号的一个部位，所述主轴 20 下方设有端台 21 ，所述副轴 50 侧边设有端点凸台 51 ，所述端台 21 设于所述端点凸台 51 下方，非工作时呈端起所述端点凸台 51 状态，所述副轴 50 与所述上盖 30 之间设有弹性元件，本实施例采用副弹簧 40 作为弹性元件，也可以采用弹片等弹性元件作为弹性元件，以此起到向下压动所述副轴 50 的作用，当然了，如果单纯利用副轴 50 的自然重力进行下压也是可以实现导通的，所述副弹簧 40 弹力小于主弹簧 90 ，所以主弹簧 90 在静止状态时的向上弹力可以完全抵消掉所述副弹簧 40 向下的弹力以及所述副轴 50 本身的重力之和，另外，为了保证副轴 50 在上下运行时不发生偏斜，特在所述上盖 30 下方设有一可供所述副轴 50 置入的滑动槽 60 ，所述滑动槽 60 呈吊篮式固定在所述上盖 30 下表面。
依借上述技术方案，本发明所提供的按键结构装配安装到键盘上之后，在使用过程中，所述键帽 10 受到使用者向下的压力，压动所述主轴 20 向下运动，而所述端台 21 随之向下运动过程中改变了端起所述端点凸台 51 的状态，放松了对所述端点凸台 51 的支撑力，所述副轴 50 不受所述端台 21 的支撑后在重力作用下或者在副弹簧 40 的弹压之下向下运动压迫所述导电膜 70 的连接点，完成导通的任务，此时，所述主轴 20 继续向下运行剩余空行程，之后在主弹簧 90 的作用下进行复位，而所述主轴 20 的端台 21 到达所述端点凸台 51 下方之时将所述端点凸台 51 抬起推动所述副轴 50 复位，所述副轴 50 的导通点 52 离开所述导电膜 70 断开连通，使所述端台 21 恢复为端起所述端点凸台 51 状态。本技术方案具有以下有益效果，具有机械键盘手感，所述主轴 20 空行程带来好的手感；所述主轴 20 下压的同时所述副轴 50 被放松即刻导通所述导电膜 70 ，而所述主轴 20 仍然继续下压，灵敏度大大提高；本技术方案所使用的元件采用塑胶材料，相对于其他机械键盘的金属元件按钮具有成本低的优势，同时，现有技术中的机械键盘通常采用 PCB 板，将按键元件焊接到 PCB 板上，所以无法使用价廉的 PET 导电膜，而本发明的技术方案可以轻松使用价廉的 PET 导电膜，致使成本大幅降低。
实施例二，

所述主轴 20 内设有第一弹簧固定圆环 22 ，所述下盖 80 内设有可与所述第一弹簧固定圆环 22 相配合的第一固定柱 82 ，所述滑动槽 33 内设有第二弹簧固定圆环 34 ，所述副轴 50 内设有可与所述第二弹簧固定圆环 34 相配合的第二固定柱 54 ，装配完成后，可以充分防止主弹簧 90 和副弹簧 40 在规定路径内伸缩，防止扭曲。
本实施例所提供的端点凸台 51 呈双耳凸出状，所述端台 21 呈双叉状，如此设计的作用主要是可以平稳端起和放松副轴 50 ，两个受力点可以使副轴 50 在上下运动过程中可以更加顺畅稳定。
本实施例另外还提供了一种 机械键盘，其包括面壳、按键、底板，所述的按键为上述的按键结构，所述的按键设于所述面壳与所述底板之间。
