摘　　要：针对普通钢丝螺套不具备防松功能,而锁紧型钢丝螺套又有安装拆卸不便等问题,运用TRIZ理论和方法,分析了普通钢丝螺套存在的技术冲突,根据冲突解决矩阵选择可用的发明原理,设计出内螺纹具有30°楔形斜面的防松型钢丝螺套。防松型钢丝螺套使用方便、操作简单,可部分替代锁紧型钢丝螺套,扩大了钢丝螺套的应用范围。General helicoil screw insert is lack of anti-loose ability, and the locking type has many problems such as mounting and dismounting inconveniently. The TRIZ theory and method are used in this paper to analyze the technical conflicts existing in helicoil screw insert. According to the conflict solving matrix, several available principles for invention are selecte, and then a new type of helicoil screw insert with 30° wedge slope is designed, which is anti-loose, convenient to use and easy to operate. The new designed anti-loose type can partially replace the locking type of helicoil screw insert, and lead to new application fields.
