With the rapid development of technology, spring's figure is everywhere, playing an irreplaceable role in all walks of life.How to use the properties of the spring itself according to local conditions will be today's small talk about the content.
Spring measuring function
We know that, within the elastic limit, the extension (or contraction) of the stretching spring, compression spring, torsion spring, bending spring, spring and spiral spring is proportional to the force.A spring scale is made from the property of a spring.
Spring compression function
Observing various electrical switches, it is found that one of the two contacts of the switch must have a spring in the head to ensure that the two heads are in close contact and conduct well.If the contact is not good, the resistance at the contact will increase, the heat generated by the current passing through will increase, and the metal at the contact will melt in a serious case.The two metal posts of the bayonet lamp holder are spring loaded for good contact.As for the central metal piece of the screw lamp holder and the metal piece of all sockets are reeds, which function to keep the two sides in close contact to keep the same good.When magnetic tape, there is a phosphor bronze reed, using its bending deformation produced by the elastic to make the magnetic head close to the tape.There is a long coiled spring in the stapler which ACTS on the one hand as the top pin, and on the other hand as the front pin is pushed out, the back pin can be sent to the front of the stapler to be pushed out comfortably, so that each pin can be automatically pushed to the front until all the pins are pushed out.In addition, like the clip that clip clothes, ballpoint pen, the clip on the pen cover are all clamped on clothes by the function of spring pressing.
Spring reset function
The spring deforms under the action of an external force.Many tools and equipment are reset by the property of spring.For example, in many buildings the door hinges are loaded with reset springs that automatically reset the door when people come in and out.People also made use of this function automatic umbrella, automatic pencil and other supplies, very convenient.In addition, a variety of buttons and buttons are also necessary reset spring.
Spring-driven function
Mechanical clocks, clockwork toys are all driven by a tight spring.When the spring is tightened, the spring produces bending deformation and stores a certain elastic potential energy.After release, the elastic potential energy changes to kinetic energy, which drives the rotation through the transmission device.
Spring buffering function
A spring is arranged between the frame and the wheels of a locomotive vehicle, which USES the spring's elasticity to slow down the jolting of the vehicle.
Spring vibration sound function
When air flows through the holes in the harmonica and accordion, it hits the reeds and the reeds vibrate.
