AI Technical Summary

Technical Problem

When existing linear motors are used in the vertical direction, if the power is suddenly cut off, the magnetic shaft will fall out of the motor body due to gravity, causing damage to the components and affecting their service life.

Method used

The system employs components such as telescopic rods, springs, sliders, movable plates, and limiting posts. When the magnetism disappears, the spring rebounds and pushes the connecting plate to move. The limiting posts are embedded in the limiting grooves to prevent the magnetic shaft from falling off. When maintenance is required, the support plate can be quickly separated and installed by rotating the screw sleeve and threaded post.

Benefits of technology

It effectively prevents the magnetic shaft from falling due to gravity when the power is off, extends its service life, simplifies the maintenance process, and reduces the difficulty of maintenance.
