一种竞技类速滑冰刀，属于滑动运动器械技术领域，本发明解决了解决传统 CLAP 式 速度滑冰冰刀的转轴部分稳定性较差，冰刀重量较重，形变能力较弱，不能适应速度滑冰 技术升级后对装备的需求，造成了持冰时间短，影响了竞技成绩的问题。技术要点：刀管 采用“T”型刀管，刀管的刀带部分为弧线型设计，刀带上两侧对称分布有凹坑；刀桥和刀 管的前端通过上刀桥连接部、下刀桥连接部和钢轴建立连接，刀桥和刀管的后端通过尼龙 座与锥形通孔倒刺紧密配合建立连接，缓冲墩的底面与刀管相抵，弹簧连接在后弹簧连接 座和前弹簧连接座之间。本发明更好地贴合冰面，增加持冰时间，提高能量转化效果，减 少运动员的能量损失，保持运动员在整个运动过程中不降速。

A competitive speed skating skate belongs to the technical field of sliding sports equipment. The invention solves the problem of poor stability of the rotating shaft of the traditional CLAP speed skating skate, heavy weight of the skate, weak deformation ability, unable to meet the equipment requirements after the speed skating technology upgrade, resulting in short ice holding time and affecting the competitive performance. Technical points: the tool tube adopts "T" type tool tube, the tool belt part of the tool tube is of arc design, and there are pits symmetrically distributed on both sides of the tool belt; The front end of the knife bridge and the knife tube is connected by the upper knife bridge connection part, the lower knife bridge connection part and the steel shaft. The rear end of the knife bridge and the knife tube is connected by the nylon seat and the taper through hole barbed closely. The bottom surface of the buffer pier is against the knife tube. The spring is connected between the rear spring connection seat and the front spring connection seat. The invention can better fit the ice surface, increase the ice holding time, improve the energy conversion effect, reduce the energy loss of athletes, and keep the athletes from slowing down during the whole movement process.
