AI Technical Summary
Existing single-screw drive structures are difficult to achieve long-stroke lifting in confined spaces, and also suffer from inconvenience in carrying and large space occupation.
It adopts a multi-section transmission structure, utilizes a planetary reducer and a double-layer lead screw design, and uses a single-stage lead screw as the main drive rod. Combined with 40RC wear-resistant lead screw material and aluminum bronze lead screw nut, heat treatment and high-frequency adjustment processes are used to achieve efficient lifting of the lead screw, and the stroke is improved by the sliding connection of guide block and guide hole.
While ensuring load-bearing capacity and stability, it achieves efficient lifting of the lead screw, featuring small size, large load-bearing capacity, high reliability, and the ability to pause and self-lock at any position, solving the long stroke requirements of traditional lead screws in confined spaces.
