I believe everyone knows that springs are indispensable in daily life. Let's introduce the tension spring. The tension spring belongs to the coil spring, which can also be called tension spring, tension spring, spiral tension spring, etc. Everyone has different names. This spring is indispensable in our daily life. It is a coil spring bearing axial tension. What is different from the compression spring is that the compression spring is a coil spring bearing axial pressure. Generally speaking, all the materials selected for the tension spring are made of circular section materials, The difference from the compression spring design is that there are two "hooks" on both sides. When there is no axial tension, all the coils are in this closed state. Let's solve what is the tension spring and its application field.
    Tension spring occupies a core position in the global market, ranging from small medical and health devices to mechanical braking springs in the field. The use of tension spring stipulates all kinds of pull rings and hooks you can specify. The close contact between adjacent spring rings causes the initial tension, which is beneficial to controlling load and stiffness. It is widely used in national defense and security, marine, electronic computers, electronic devices, automobiles Plastic mould, medicine, biochemistry, aerospace, railway transportation, nuclear power, wind power, thermal power, engineering machinery, mining machinery, construction machinery, elevator and other industries.
