What Are Torsion Springs?

Torsion springs are helical springs that work by twisting their ends to apply rotational force or torque. В отличие от пружин сжатия или растяжения, torsion springs operate in an angular motion, making them ideal for applications requiring rotational energy.

Ключевые особенности:

• Материал: Typically made of durable materials like stainless steel, углеродистая сталь, or alloy steel.
• Дизайн: Ends are either straight, hooked, or bent to fit the lock mechanism.
• Compact: Small size with high energy efficiency.
• Универсальный: Can be designed for both clockwise and counterclockwise operation.

Role of Torsion Springs in Door Locks

Torsion springs in door locks control the rotational movement of lock components, ensuring smooth operation and reliable performance. Commonly, they are used in mechanisms like:

• Засовы: Assists in retracting or extending the bolt.
• Latch Locks: Provides consistent torque for the latch.
• Кулачковые замки: Enables precise movement of the locking cam.
• Умные замки: Ensures return-to-neutral position for enhanced functionality.
