AI Technical Summary
Technical Problem
然而，在实际使用过程中，尤其是在小吃摊、移动厨房等高频弯曲、频繁移动的环境中，现有燃气波纹软管的结构设计仍存在明显不足
Benefits of technology
本实用新型所提供的一种抗弯折燃气用波纹软管，将传统的直边外扣环改进为圆弧外扣环，圆弧外扣环的内侧壁采用圆弧过渡面设计，从根本上消除了传统扣环棱角的应力集中点，当波纹管体在频繁移动或弯曲时，弯曲应力通过该圆弧过渡面被转化为分布均匀的压应力，并平顺地传导至内部的被覆层和波纹管体，有效避免了应力在扣环边缘的聚集，解决了塑层因局部剪切力而开裂、脱落的技术难题，极大地提升了波纹管体在高频弯曲使用场景下的耐久性与可靠性；
