Hardware spring

Hardware spring also known as metal spring. It's a mechanical part that USES elasticity to work. The main helical spring, coil spring, stainless steel spring, shaped spring.

Function is introduced

Press function

Observe all sorts of electric equipment switch to be able to discover, in the two contacts of the switch, have a head to install spring necessarily, in order to assure two head to contact closely, it is to conduct good. If the contact is not good, the resistance at the contact will increase, the heat generated by the current will increase, and the metal at the contact will melt in severe cases. The two metal posts of the bayonet lamp holder are also equipped with springs for good contact; As for the central metal sheet of the screw cap and all the sockets, the metal sheet is reeds, whose function is to keep both sides in close contact to keep them in good condition. When a magnetic tape has a phosphorous bronze reed, the head is in close contact with the tape, using the force produced by its bending. In the stapler there is a long coil spring its role on the one hand is the top nail, on the other hand, when the front of the nail is pushed out, can be sent back to the front of the nail to prepare comfortable push out, in this way, can automatically push a nail to the front, until the nail all pushed out. Many machines feed automatically. In addition, clips such as those on clothing clips, ballpoint pens, and pen covers are clamped onto clothing using the spring's compression function.

Drive function

Mechanical clocks, clockwork toys are driven by the winding up. When the spring is tightened the spring produces a bending deformation, storage of a certain elastic potential energy. After release, the elastic potential energy turns into kinetic energy, which is driven by the transmission device.

Reset function

Spring deformation under the action of external force, remove the external force, the spring can return to the state. Many tools and equipment are using the spring property to restore position. For example, many buildings have reset springs on the hinges of their doors that automatically reset when people go in and out. People also use this function made into automatic umbrella, automatic pencil and other supplies, very convenient. In addition, a variety of buttons and keys also necessary reset spring.

The buffer function

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

Measurement functions

We know that the extension (or contraction) of the spring is proportional to the external force within the elastic limit. Spring using this property made of spring balance.

Vibration and sound function

When air flows through the reed holes in the harmonica or accordion, the reeds are struck and the reeds vibrate to produce a sound.
