At present, there are more and more large-scale outdoor clocks. You may not have such a big experience in your daily life. However, during the Spring Festival, especially during the countdown to the New Year, many people will gather at the bronze bells. Wait for the bell to ring. But I don’t know if you have noticed such a thing. Large outdoor clocks can be divided into two needles and three needles. The large outdoor clocks you encounter in your daily life are usually two needles, but why are most outdoor clocks Is it two stitches? Let me take a look together below.
The so-called two-handed outdoor clock is actually the kind of clock without a second hand. The expressive function of the second hand in the clock is very lacking. Except for the timing requirements, other times are used very little at that time, and it will also appear at the whole hour. To tell the time, this causes the second hand to play a more subtle role.
The main reason why those large outdoor bronze clocks do not have a second hand has not been clearly expressed until now. But according to most people, the clock hand of an outdoor clock spends a lot of kinetic energy every time it goes around, and the role of the second hand in a large clock is not very prominent, and you don’t know it in your daily life. Pay attention to the value of the second hand, in order to save costs, the second hand is subtracted.
In addition, there will be a little friction during the operation of the three clock hands. This kind of friction will damage the outdoor clock to a certain extent, and the maintenance of the outdoor clock is very difficult. In order to reduce maintenance times, thus subtracting the second hand.
