Before, we have introduced you to the practical application of springs in life, so besides the practical application, what additional functions does the spring have?

Here, Zhuhai Xinlong Technology will introduce you one by one:

1. Measurement function

We know that within the elastic limit, the extension (or contraction) of the spring is proportional to the external force. Use the nature of the spring to make a spring balance.

2. Reset function

The spring is deformed under the action of external force, and after the external force is removed, the spring can be restored to its state. Many tools and equipment use the nature of springs to reset. For example, many building door hinges are equipped with return springs. After people enter and exit, the door will automatically reset. People also make use of this function to make automatic umbrellas, automatic pencils and other supplies, which is very convenient. In addition, various buttons and keys are also indispensable for return springs.

Three, drive function

Mechanical clocks and clockwork toys are driven by winding up the clockwork. When the mainspring is tightened, the mainspring is bent and deformed, storing a certain amount of elastic potential energy. After release, the elastic potential energy is transformed into kinetic energy, which is driven to rotate through the transmission device. In toy guns, starting guns and military guns, they also work with springs.

Four, buffer function

A spring is installed between the locomotive frame and the wheel, and the elasticity of the spring is used to slow down the bumps of the vehicle.

Five, voice function

When air flows from the reed hole in the harmonica or accordion, it impacts the reed and the reed vibrates to make a sound.

6. Squeeze function

Observing various electrical switches, you will find that one of the two contacts of the switch must be equipped with a spring to ensure that the two contacts are in close contact and are in good conduction. There is a long coil spring in the stapler. On the one hand, the function is to tighten the staples, and on the other hand, when the front staple is pushed out, the back staples can be sent to the front so that the staples can be pushed out comfortably. This will automatically push the nails to the front one by one until all the nails are pushed out.

In addition, clips such as clothes clips, ballpoint pens, and clips on the pen case are all clamped to the clothes by the pressing function of the spring.
