The functions and applications of various springs

• Compression springs, referred to as compression springs, primarily serve the purpose of storing energy and then rebounding, with the direction of force opposite to that of the applied force. They can be used in pressure-related structures, such as buttons;
• Tension springs, also known as tension springs, primarily serve the purpose of storing energy and then rebounding, with the direction of force opposite to that of the applied force, which can be understood as exactly opposite to compression springs. They can be used in tension-related structures, such as force gauges;
• Twist springs, referred to as torsion springs, primarily also serve the purpose of storing energy and then rebounding, with the direction of force tangent to that of the applied force. They can be used in thrust-related structures, such as self-locking doors;
• Torsion springs can be used in thrust-related structures, primarily serve the purpose of storing energy and then rebounding, such as the positive and negative terminals of batteries;

Disc springs primarily serve the purpose of buffering and can be used in structures designed to lock against loosening. Due to the relative rarity of disc springs, their uses are extensive and they belong to commonly used items. They are mainly used in shock absorption, clamping, energy storage, and force measurement, among other aspects. There are many structural forms of springs, among which cylindrical helical compression springs are quite common.
