How to draw an antique clock?
First we draw two circles, a big circle and a small circle. Then we draw the fixed angle of the clock on the outside of the big circle and draw the bell ears on it. Then draw 3, 6, 9, 12 hours in the circle. Then we draw an hour hand and a minute hand in the middle. Finally, we color the finished clock, so that the clock is finished.
First of all, the explanation of the clock
Clock, wine vessel, also a kind of wine vessel, prevailed in Han Dynasty. Xu Shen said in Shuo Wen Jie Zi: "Clock, wine vessel. From Jin Zhongsheng. " In ancient times, there was a saying that "Yao and Shun had a thousand bells", and later "Zhong" was also connected with "Zhong".
The clock is shaped like a bottle, with a bulging belly and a thin neck, but it is bigger than the bottle. Mainly used for holding wine or storing grain. As an ancient unit of capacity, "Zhong" can hold six sticks and four buckets, usually "ten pots and one bell". Mencius said, "What's the use of ten thousand minutes for me?" To show that ill-gotten wealth is like dirt.
Second, the structure and function
A clock is a tool for measuring and displaying time. The diameter of the movement is generally greater than 50mm and the thickness is generally greater than12 mm. It is usually used in a certain position. Some modern small clocks and watches are also equipped with a watch core and a bell shell.
The development of clocks has experienced thousands of years of history (see the history of clock technology). With the continuous expansion of the scope of use, modern clocks and watches have more functions and more types. Generally, it can be classified according to vibration principle, energy and structural characteristics and main uses, and is often named by several classification methods.
