How do the springs inside the lock body work together?

1. Spring-Driven Reciprocating Movement of the Lock Bolt

When the user rotates the lock handle or enters the password, the main spring (or tension spring) inside is compressed or released, generating a forward or backward thrust that causes the lock bolt to slide quickly within the lock body, locking or unlocking.
2. Dual-Spring Structure Improves Prying Resistance

Modern disc brake locks often use a "dual resistance" design, adding an auxiliary spring to the main spring. These two springs share the external force, distributing the shear stress during prying and significantly improving pry resistance.
3. Spring-Catch Interaction

After the spring's travel is complete, a catch or retaining block secures the lock bolt in a pre-set position, preventing it from accidentally releasing due to spring rebound and ensuring the lock body remains secure even under load.
4. Spring-Loss Prevention

To prevent the spring from falling during assembly or use, a circular platform or groove is incorporated into the lock body to hold the spring in place, ensuring it remains in a controlled position and improving overall reliability.

How does the DiscBrakeLock guarantee security?
1. Hardened Steel and Drill-Resistant Construction

The lock body is constructed of hardened steel with a bright chrome or nickel plating finish, providing exceptional resistance to drilling and impact damage, preventing direct tool damage to the lock cylinder.
2. Tamper-Resistant Cylinder and Dual Locking Mechanism

It features a dual-resistance anti-theft cylinder with a main and auxiliary spring working together, along with a tamper-resistant locking plate and lock block, providing multi-point locking and significantly enhancing anti-pry and anti-shear performance.
3. Weather-Resistant Coating and Rust-Resistant Treatment

The disc brake lock is coated with a weather-resistant and rust-resistant coating to withstand harsh environments like rain and salt spray, maintaining its mechanical strength and cosmetic integrity through long-term use.
4. OEM-Level Quality Control System

Our production process adheres to international quality management systems such as ISO9001. We undergo rigorous strength, corrosion resistance, and functional testing before shipment to ensure that every lock meets global security standards.
