Clocks have always been one of the products of Chinese people.Since the founding of New China, the state has invested a large amount of capital to develop the watch industry, which has enabled the industry to develop rapidly. Since then, Chinas reform and opening up and economic global development have brought prosperity to the Chinese watch industry.So what are the clock categories in the market?What is the working principle of watch?Lets take a look!
What are the categories of clocks and watches
There are two types of modern watches: mechanical power and electricity.
Mechanical clock
The mechanical watch is a type of gear operation with the power of the release of the energy to release the energy as the power of the heavy hammer or spring.
Electronic clock
Electronic clocks are a modern power that appears in modern times. LCD displays digital and quartz pointer.
Watching work principle
The scope of the clocks has a wide range of applications, and there are many varieties, which can be classified according to the principle of vibration, structure and use characteristics.According to the vibration principle, it can be divided into clocks that use lower -frequency mechanical vibrations, such as clocks, waging clocks, etc.; Use of high -frequency electromagnetic oscillations and quartz oscillating clocks, such as stepping electric clocks, quartz clocks, etc.; According to structural characteristicsIt can be divided into mechanical watches such as mechanical alarm clocks, automatic, calendar, dual calendar, and spring;Yin fork electronic clock, pointer, and digital display quartz electronic clocks.
Structure form of clocks
The mechanical watch has a variety of structural forms, but its working principles are basically the same. They are composed of the original movement system, transmission system, escapement speed device, pointer system, and upper needle system.
The mechanical watch uses the clockwork as the original movement system of the power, and the transmission system composed of gears to promote the escapement speedr; then the escapement speedr will be used to control the speed of the transmission system;At the same time as the speedor, the pointer mechanism is also driven, the speed of the transmission system is controlled by the escapement speed, so the pointer can indicate the time on the dial in accordance with a certain rule;Machine.
In addition, there are some additional institutions that can increase the functions of clocks, such as automatic upper -bar institutions, calendar (dual calendar) institutions, time of time, moon phase instructions, and measurement time institutions.
