一种冰刀快速更换结构 技术领域
本发明涉及冰刀技术领域，特别涉及一种冰刀快速更换结构。
背景技术
体育运动是全民健身的重要项目，滑冰项目是冰上体育运动主要项目之一。运动员在冰上滑冰时以高超技术和优美的舞姿，展现出体育运动的靓丽风采，为体育运动增添了令人耀眼的光彩。
冰刀使用过程中出现了缺口或者使用时间比较长了就要及时更换，否则在滑冰时用不上力是非常危险的，很容易摔倒的；现在的溜冰鞋更换冰刀非常麻烦，对于一些紧急情况(如比赛时)需要快速更换冰刀时，而不能将冰刀快速安装在溜冰鞋的刀架上，进而会影响更换的效率，有时会造成更大的影响，且多数时候使用者更换冰刀的时候为单手操作的较多，现有的技术中单手操作的结构通常并不容易做到方便快速，且更换冰刀的机构很多时候处于暴露状态，在激烈的滑行过程中十分容易碰到外物造成误解锁，给使用者容易造成很大的安全隐患。
故此，现有的冰刀更换结构需要进一步改善。
发明内容
本发明的目的是为了提供一种结构简单，更换方便、快速且安全的冰刀快速更换结构。
为实现上述目的，本发明提供如下技术方案：一种冰刀快速更换结构，包括有：刀架，所述刀架具有前置支撑壳、后置支撑壳与连通于该前置支撑壳和该后置支撑壳下方用于安装刀片的安装槽；限位部，所述限位部设置在安装槽的后端位置处，用于固定刀片的后端部；旋转卡勾，所述旋转卡勾铰接在所述前置支撑壳内，用于固定刀片的前端部；至少一个弹性压紧装置，所述弹性压紧装置设置在所述前置支撑壳内，用于使所述旋转卡勾保持锁定刀片；解锁部件，所述解锁部件设置在所述前置支撑壳内，所述解锁部件一端顶压在旋转卡勾上部后侧面，用于顶压旋转卡勾使其与刀片脱离解锁，另一端延伸并穿出前置支撑壳外侧；保险部件，所述保险部件设置在所述前置支撑壳上并与解锁部件连接，用于限制解 锁部件的移动。
进一步地，还包括有快速弹出装置，所述快速弹出装置包括有设置在所述前置支撑壳内且下方开口的导向圆槽，在所述导向圆槽内上下滑动有弹出圆柱与使所述弹出圆柱保持向下弹动的第一弹簧，所述弹出圆柱下端与刀片前端上侧相抵。
进一步地，所述限位部包括有贯穿设置在安装槽后端部的通孔，在所述通孔内插设有与刀片后端的U形凹槽配合的固定轴。
更进一步地，所述固定轴为铆钉。
进一步地，所述弹性压紧装置为扭簧，所述扭簧套设在旋转卡勾的铰接轴上。
进一步地，在所述旋转卡勾上端设有止旋块。
进一步地，所述解锁部件包括有设置在前置支撑壳内的限位滑槽，在所述限位滑槽内前后滑动有驱动顶块，所述驱动顶块前端与止旋块的后侧相抵，在所述前置支撑壳后侧前后滑动有解锁横杆，所述解锁横杆前端与驱动顶块后端相抵。
进一步地，所述解锁横杆后端延伸至前置支撑壳的后侧并设有推钮，在所述前置支撑壳外侧设有推钮置放槽，所述推钮活动设置在推钮置放槽内。
进一步地，所述保险部件包括有设置在推钮上端的轨道槽，在所述轨道槽内上下滑动设有保险卡块，在所述推钮置放槽上侧设有限位缺槽，在所述轨道槽与保险卡块之间连接有能使保险卡块保持伸进限位缺槽内的第二弹簧。

具体实施方式
下面结合附图说明和具体实施方式对本发明作进一步描述：如图1至5所示的一种冰刀快速更换结构，包括有刀架1，所述刀架1具有对应前脚掌位置的前置支撑壳3和设置在对应后脚掌位置的后置支撑壳4以及形成于该前置支撑壳3和后置支撑壳4下方，并与该前置支撑壳3和后置支撑壳4均相互连通且用于安装刀片2(刀片2指传统意义上的冰刀)的安装槽5；限位部6用于固定刀片2的后端部，所述限位部6设置在对应后脚掌位置的安装槽5内的位置处；旋转卡勾62用于固定刀片2的前端部，该旋转卡勾62铰接在所述前置支撑壳3内；旋转卡勾62底部具有一能与冰刀上的勾体进行配合的卡勾，其位于铰接轴的上方具有一凸出部分即止旋块63，该旋转卡勾62整体由前向后看的截面为一十字形(请参见图4)；至少一个弹性压紧装置64用于使所述旋转卡勾62能保持锁定刀片2的状态，所述弹性压紧装置64设置在所述前置支撑壳3内；解锁部件7，所述解锁部件7设置在所述前置支撑壳3内，所述解锁部件7一端顶压在十字形旋转卡勾62位于铰接轴上端凸出的止旋块63后侧面，用于顶压旋转卡勾62使其能与刀片2脱离解锁，另一端延伸并穿出前置支撑壳3壁面外侧，该解 锁部件7的延伸方向与冰刀长度方向一致；保险部件9用于限制解锁部件7的移动，所述保险部件9设置在所述前置支撑壳3上并与解锁部件7滑动连接，该保险部件锁定时，其一部分本体将处于紧贴所述前置支撑壳3外壁面，解锁后与所述前置支撑壳3外壁面脱离。
如图2至4中所示，本发明中还包括有能将刀片2弹出的快速弹出装置，所述快速弹出装置包括有设置在所述前置支撑壳3内且下方开口的导向圆槽91，在所述导向圆槽91内上下滑动有弹出圆柱92与使所述弹出圆柱92保持向下弹动的第一弹簧93，所述弹出圆柱92下端与刀片2前端上侧相抵，当旋转卡勾62与刀片上的固定卡勾10脱离时，通过第二弹簧93的弹力，使弹出圆柱92弹出，从而将刀片2前端弹出安装槽5，方便拆出刀片2，提高更换刀片的效率。
参见图2至图3所示，所述限位部6包括有贯穿设置在安装槽5后端部(即：对应后置支撑壳4下方位置)的通孔21，在所述通孔21内插设有能与刀片2后端的U形凹槽11配合的固定轴22，所述固定轴22优选为铆钉，通过铆压方式安装固定轴22，结构简单，安装方便，将刀片2的后部U形凹槽11斜向卡入安装槽5内固定轴22上，翻转刀片2前端，并按压刀片2前端使其***安装槽5内，进而挤压旋转卡勾62底部的卡勾一侧，使旋转卡勾62产生翻转后，继续按压压刀片2前端使其本体上的勾体越过旋转卡勾62底部的卡勾，此时旋转卡勾62复位将底部的卡勾卡入刀片2前端的勾体上，进而固定，其中旋转卡勾62底部的卡勾与刀片2前端的勾体接触面均设有斜面以及圆弧倒角，方便相互挤压位移，其具体形状结合附图理解。
本发明中所述弹性压紧装置64为扭簧，所述扭簧套设在旋转卡勾62的铰接轴上，扭簧一端锚点在旋转卡勾62上，另一端锚点则置于前置支撑壳内壁上；当使用者将刀片2伸进前置支撑壳3内时，刀片2上的固定卡勾10撞击旋转卡勾62的斜面部分，并克服了扭簧的扭力，从而允许固定卡勾10卡进旋转卡勾62内，再由扭簧的力将其固定卡勾10锁定。
本发明中所述解锁部件7包括有设置在前置支撑壳3内的限位滑槽65，在所述限位滑槽65内前后滑动设有驱动顶块66，所述驱动顶块66前端与止旋块63的后侧相抵，在所述前置支撑壳3后侧前后滑动有解锁横杆8，所述解锁横杆8前端与驱动顶块66后端相抵，驱动顶块66与解锁横杆8可以为分体设置，也 可以为一体设置为一长条形部件，其中，解锁横杆8穿过前置支撑壳3外壁的一端上滑动安装保险部件9，安装时，刀片2沿固定轴22旋转，旋转卡勾62与固定卡勾10相碰撞的面均有斜面结构，当旋转卡勾62顶压到固定卡勾10时，并克服了扭簧的扭力，从而允许固定卡勾10卡进旋转卡勾62内，再由扭簧的力将其固定卡勾10锁定，进而实现固定锁紧功能；解锁时，通过驱动解锁横杆8顶动驱动顶块66，而驱动顶块66一端顶动止旋块63，从而使旋转卡勾62旋转与固定卡勾10脱离实现解锁；另外，首先止旋块63能起到限位旋转卡勾62的作用，防止旋转卡勾62因扭簧64的力使其旋转角度过大不能与固定卡勾10配合，其二能够通过驱动顶块66顶动止旋块63，从而带动旋转卡勾62旋转与固定卡勾脱离，实现解锁的作用。
本发明中所述解锁横杆8后端延伸至前置支撑壳3的后侧并设有推钮71，在所述前置支撑壳3外侧设有推钮置放槽72，所述推钮71活动设置在推钮置放槽72内，通过推钮71的设置，能够更加舒适、方便的驱动解锁横杆8移动。
本发明中所述保险部件9包括有对称设置在推钮71上端的轨道槽81，在所述轨道槽81内设有能上下滑动保险卡块82，在所述保险卡块82表面优选的设有多个防滑凸条，在所述推钮置放槽72上侧设有限位缺槽83，在所述轨道槽81与保险卡块82之间连接有能使保险卡块82保持伸进限位缺槽83内的第二弹簧84，解除保险时，将保险卡块82沿轨道槽81向下滑动，此时保险卡块82与限位缺槽83的壁面脱离，然后通过推动保险卡块82与推钮71一起往推钮置放槽72内移动，从而带动解锁横杆8顶动解锁部件7实现解锁，以这种方式，首先能起到锁定限位解锁横杆8的作用，同时能防止推钮71意外接触冰球球棍、冰球等外物而导致误解锁，进一步保障使用者的安全。
参见图2-4所示，在所述驱动顶块66前端与前置支撑壳3内壁之间连接有第三弹簧99，优选的，在止旋块63的两侧均设有第三弹簧99，能够让驱动顶块66保持有一个向后的力，使其驱动顶块66更加稳定的固定在限位滑槽65内，并能保障驱动顶块66的顺畅滑动。
为了能让刀片2更加稳定、牢固的安装于安装槽5内，参见图2或3所示，刀片2上的固定卡勾10与U形凹槽11大致呈对称设置，且靠近刀片2的中心位置处，进而能提升刀片2的承受力，延长刀片2的使用寿命，同时能保障刀片2 更加稳定牢固的安装在安装槽5内，保障使用者的安全。
为了进一步加强旋转卡勾62与固定卡勾10的固定强度，所述旋转卡勾62与止旋块63为一体成型的锌合金材质，锌合金具有所有合金的特新，重量轻、强度高、热传导性比钢铁低、耐腐蚀等。
本发明的具体工作原理：首先安装时，将U形凹槽11卡进固定轴22，后刀片2沿固定轴22旋转，使固定卡勾10伸入前置支撑壳3内并与旋转卡勾62配合，旋转卡勾62将固定卡勾10锁紧，进而通过限位部6与旋转卡勾62将刀片2牢牢的固定在安装槽5内；拆卸时，首先将保险卡块82沿轨道槽81向下按动，此时保险卡块82与限位缺槽83脱离，后通过带动保险卡块82与推钮71一起往推钮置放槽72内移动，从而带动解锁横杆8顶动驱动顶块66移动，驱动顶块66顶动止旋块63，从而带动旋转卡勾62旋转与固定卡勾10脱离，最后通过第一弹簧93的弹力，使弹出圆柱92弹出，从而将刀片2前端弹出安装槽5，实现解锁的作用；进而整套的安装与拆卸极其的方便快速，提升了刀片的更换速度。
以上显示和描述了本发明的基本原理和主要特征以及本发明的优点，本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
