What is the structure of an umbrella?

The structure of the umbrella includes four parts: the umbrella handle, the umbrella rib, the umbrella surface, and the umbrella cover. The umbrella handle is the backbone of the umbrella, supporting the whole umbrella. It is mainly made of wood, bamboo, metal, and other materials. The umbrella rib supports the entire umbrella surface. The umbrella cover is the most important part of the umbrella, which bears the responsibility of covering the rain. It is made of plastic cloth, oilcloth, silk cloth, and durable nylon cloth. At the same time, put the umbrella into the umbrella cover when entering and leaving the bus and shopping malls, which can reduce the dripping of the water to the ground and play the role of a civilized umbrella. The latest design structure is that the umbrella cover and the umbrella are self-contained, which can prevent the loss of the umbrella cover.
