AutoTwist Lock

grabcad

The automatic locking system works similarly to a retractable ballpoint pen mechanism but is modified for its purpose. By pushing the upper side down, the blue-colored locking lever rotates 90 degrees based on its previous position, enabling locking and unlocking alternation. The locking concept can also be realized with different rotation angles, such as 120 degrees, providing two locked positions and one unlocked for translocation. This mechanism requires no additional steps; simply place the upper container onto the lower one to lock, or move them together to unlock automatically. To lock again, lift slightly and place the upper container back on the lower one. The material is tool steel, manufactured through milling or casting+milling.
