Mechanical Combination Door Lock
Product Introduction:
A mechanical combination door lock is a type of lock that unlocks the door through a mechanical structure and a combination of numbers. Its main feature is that it can be opened by a set combination of numbers without using a key. Combination locks are usually made up of multiple rotating wheels or gears, each with different numbers or symbols, and the user needs to adjust these wheels with the correct combination to unlock the door lock.
- Rotary lock: Each wheel is engraved with numbers, and the user rotates and adjusts the wheel to unlock it in a specific order and combination.
- Latch combination lock: The lock is opened and closed by setting different positions of the latch.
- Dial combination lock: Similar to the rotary wheel lock, but requires more precise dialing and setting.
The advantages of this type of door lock include that it is not easy to copy and has no electronic components, so it is not easily affected by battery or circuit problems. However, the disadvantage is that if the combination number is lost or forgotten, it will become very difficult to unlock.
Mechanical combination locks are widely used in safes, suitcases, filing cabinets, and access control systems that require high security.
