AI Technical Summary

Technical Problem

When installing or removing the high-strength springs of the hanging device of a drum washing machine, there is a lot of resistance during the stretching process, and it is quite difficult for workers to stretch and hang the springs by hand.

Method used

The spring has mounting blocks at both ends. Through the connection structure and telescopic structure, the spring is stretched by the screw and threaded sleeve. The reaction force after the spring is stretched is borne by the screw and threaded sleeve. The rotation range of the rotating block is limited by the sliding groove and sliding column, and the friction is increased by the rubber pad to maintain stability.

Benefits of technology

The reduced resistance when stretching the spring ensures the rotating block remains in the correct position, simplifies the installation and disassembly process, and improves the ease and stability of operation.
