Extension Spring

Tension springs (also called tension springs, referred to as tension springs) are helical springs that bear axial tension. Tension springs are generally made of round cross-section materials. When not under load, the coils of the tension spring are generally tight and there is no gap.

The working principle of the extension spring is just the opposite of that of the compression spring. The compression spring has a reverse effect when there is pressure, and the extension spring has a reverse effect when it is stretched. When the tension spring is pulled apart, the spring wants to pull back, which creates a force.

Extension springs can absorb and store energy. The difference between extension springs and compression springs is that under certain tension or no tension, this initial state determines the tightness of the extension spring. In this way, controlling the initial force can meet the unacceptable demand.

The two ends of the tension spring are fixed to other components at the time, and then when these components are separated, the tension spring has an effect, and the coils are close together to produce a strong tensile force. These components are connected together.

These spring coils are tightly connected together without tension. The closing of the spring includes hooks hanging on other components, as well as small holes and geometric interfaces. With these fixed on the components that need to be connected, it is not The problem is that when there is tension, it will provide a certain degree of resilience for these components.
