AI Technical Summary

Technical Problem

Existing cable fixing devices are prone to variations in the compressive force between the cable and the clamping mechanism when subjected to tensile stress. This can cause the cable to easily detach, making it impossible to effectively secure the cable end and affecting the strength testing results.

Method used

The system employs a combination of a winding rod, a through hole, an adjusting screw, and a clamping block. The winding rod is fixed to the cable by winding it around. The friction between the cable and the winding rod, combined with the adjusting screw, drives the clamping block to rise and fall. The clamping block and the winding rod are connected by a snap-fit ​​groove and a cover plate, which limits the winding rod. The arc-shaped structure design secures the cable winding rod, ensuring it does not rotate. The arc-shaped through groove and the screw allow for limiting and fine-tuning of the fixed base. The mounting bolt and the pressure spring provide a buffer function.

Benefits of technology

It improves the fixation effect of the cable end, prevents the cable from loosening, enhances the consistency between the cable and the direction of the tensile force, and improves the accuracy and reliability of strength testing.
