AI Technical Summary
Traditional constant temperature water baths lack effective mechanical control, resulting in cumbersome and laborious experimental operations. They also cannot quickly connect and disconnect experimental equipment, and cannot meet the needs of adjusting the position and height of equipment under different experimental conditions, thus affecting experimental efficiency and convenience.
A mechanical lifting device for an integrated constant temperature water bath used for Soxhlet extraction was designed. It adopts a transmission structure of worm gear, worm wheel, gear and rack, combined with lifting plate and clamping mechanism. The condenser tube, extraction tube and receiving bottle can be quickly positioned and moved by rotating the handle outside the adjustment box. The clamping mechanism adopts a snap-on connection design of fixed clamping plate and movable clamping plate to avoid damage to the equipment.
This has improved the convenience and efficiency of experimental operations, allowed for flexible adjustment of the position and height of the equipment, reduced experimental errors, extended the service life of the equipment, and improved the accuracy and repeatability of experimental results.
