AI Technical Summary

Technical Problem

Existing telescopic lifting devices are not securely fixed after length adjustment, are complicated and time-consuming to operate, and pose safety hazards, especially affecting production efficiency and safety in high-frequency and high-intensity working environments.

Method used

It adopts a plug-in structure of plug rod and fixed sleeve, combined with a locking system of card slot and card block. The sliding connection of strip groove and positioning bar prevents rotational misalignment. The linkage design of slider and push block provides simple and intuitive operation. Push spring provides continuous and stable elastic support for push block. The top block in the movable hole and compression spring combine to form an automatic pop-out mechanism. The limiting mechanism constructs a double insurance system to prevent accidental unlocking through the combination design of limiting sleeve and connecting sleeve.

Benefits of technology

It achieves stepless adjustment of the lifting robotic arm, ensuring accurate positioning and easy operation, improving work efficiency and safety, and is particularly suitable for high-frequency adjustment and high-intensity work environments, while reducing maintenance costs.
