AI Technical Summary
Technical Problem
目前，速差器通过挂钩装置与人员或者货物相连接，现有的挂钩装置中会设置指示器，在指示器上会设置一个指示件，通过观测改指示件的位置变化来判定挂钩装置的使用情况，但是具客户反映，实际使用时产品的使用效果欠佳，挂钩装置起到的提醒效果不佳
Benefits of technology
[0005]采用上述技术方案的优点：当指示器未发生轴向窜动时，此时第一指示部处于可视状态而同时第二指示部处于遮挡状态，使用者目测到第一指示部便可明确速差器使用状态良好，当指示器发生轴向窜动后，此时的第一指示部处于遮挡状态而同时第二指示部处于可视状态，使用者目测到第二指示部便可明确速差器已发生损坏，也就是说，本方案的指示器具备两个位置状态可视化的功能，能保证使用人员对速差器状态进行精准判定，通过设置防脱连接结构，使得指示器和挂钩座的连接更可靠，通过采用钩环部和旋转挂钩的配合设计，实现了旋转挂钩与连接组件可拆卸更换的目的，在速差器损坏后，无需全部更换，降低了使用成本，因此本产品具有结构合理、使用更安全也更可靠、使用效果更佳、且能对使用状态起醒目提醒的效果。
