Iron Lid Technology Analysis and Advantages

Spiral Rolled Iron Lid: Curved rolling resembling the texture of螺蛳shells

Iron cover simple machinery is a variation of the inclined plane. The spiral on the surface of a cylinder, resembling the spiral on a snail shell, is called the male spiral, while the spiral inside an object's hole is called the female spiral. When the male and female spirals are paired, rotating one allows both to move along the spiral. The tighter the threads, the larger the spiral diameter, the less effort required.

The Advantages of Iron Lids:

Enhance the robustness of drums/box drums.

The iron lid makes the entire drum more aesthetically pleasing, generous, and beautiful.

The base features a concave design, and the iron lid allows for secure stacking of barrels, ensuring stability and evenness. Additionally, the base maintains a certain distance from the ground, preventing moisture and wear during transportation.
