一种非圆管型大道速滑冰刀。冰刀是滑冰运动中重要的装备，根据使用项目的不同，分为速滑冰刀，花样冰刀和冰球冰刀，根据项目特点的不同上述三种冰刀的刀体设计也不同，由此可以看出刀体的外形设计对运动项目本身起到了决定性的作用。一种非圆管型大道速滑冰刀在满足传统圆管型大道速滑结构技术要求的前提下，通过更为合理的结构设计，提升了刀体的整体抗扭能力同时达到了轻量化的目标。

The utility model relates to a non-circular tube type speed skating skate. Ice skates are important equipment in ice skating. They can be divided into speed skating ice skates, figure ice skates and hockey ice skates according to different items. According to the different characteristics of the project, the blade design of the above three ice skates is also different. It can be seen that the shape design of the blade plays a decisive role in the sports project itself. On the premise of meeting the technical requirements of the traditional circular road speed skating structure, a non-circular road speed skating skate improves the overall torsional resistance of the blade body and achieves the goal of lightweight through more reasonable structural design.
