AI Technical Summary

Technical Problem

In existing FIBC strength testing devices, the connecting piece between the positioning strip and the support rod is difficult to slide, which prevents the positioning strip from moving up and down, and in severe cases, renders the device unusable.

Method used

By using the pressing action of the pressure block and the positioning strip, and controlling the lifting and lowering of the first push rod through the first control component, the positioning strip can be reliably engaged and disengaged. Combined with the design of the limit barrel and the connecting piece, the positioning strip can be moved stably.

Benefits of technology

This extends the lifespan of the device, avoids situations where the positioning bar cannot move, and improves the reliability and efficiency of testing.
