- Lock Body Assembly: As the core component of bus lock systems, it incorporates precision structures such as lock bolts and cylinders, paired with anti-pry buckles to enable secure locking and safe unlocking of vehicle doors.
- Striker/Latch Plate Assembly: Mounted on the bus door frame, it engages precisely with the lock bolt of the lock body, ensuring stable door closure and preventing abnormal noise during vehicle operation.
- Internal & External Control Mechanism: Composed of interior and exterior door handles as well as connecting rod assemblies, it transmits mechanical force for door opening and closing, achieving silent and smooth door operation.
- Emergency Unlocking Device: A built-in independent structure that allows manual door opening in emergencies such as key loss or lock body failure, enhancing usage safety and emergency response capability.
- Sealing & Protective Components: Including dust covers and waterproof rubber sleeves, these parts isolate rainwater, dust and other corrosive substances, slowing down rusting and aging of internal lock components and adapting to various severe operating conditions.
