What Are Torsion Springs?

Torsion springs are helical springs that work by twisting their ends to apply rotational force or torque. Unlike compression or extension springs, torsion springs operate in an angular motion, making them ideal for applications requiring rotational energy.

คุณสมบัติที่สำคัญ:

• วัสดุ: Typically made of durable materials like stainless steel, เหล็กกล้าคาร์บอน, or alloy steel.
• ออกแบบ: Ends are either straight, hooked, or bent to fit the lock mechanism.
• Compact: Small size with high energy efficiency.
• Versatile: 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:

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