One、What are the models of copper hanging locks?
1、Leaf structure locking mechanism
These locks utilize variously shaped metal plates to create barriers, thereby achieving locking functionality.

2、Interlocking locking mechanism
Comprising a main lock and a secondary lock, the main and secondary locks are interlocked. Connecting the two secondary locks secures the main lock. The main lock can only be opened after both secondary locks are unlocked and removed.
3、Magnetic locking system
based on the principle of magnetic repulsion, the system utilizes a magnetic locking mechanism. A permanent magnet metal plate, identical to the key's magnet, is placed between the locking mechanism slot and the retaining pin. The key, which does not directly contact the retaining pin, is inserted smoothly into the locking mechanism slot, generating a strong repulsive force that easily opens the lock. Additionally, the system utilizes the principle of magnetic attraction to firmly hold the metal plates, enabling the lock to open with the help of a spring.
4、Spring-loaded locking mechanisms
This type of lock utilizes a cylindrical pin within the lock mechanism to create an obstruction, preventing the lock from turning and achieving a locking function. The pin structure is also a commonly used structure in locks. Some locks are constructed with multiple layers of metal sheets, giving a solid and robust impression, and are referred to as "multi-layered locks." However, these locks also utilize a pin structure, so they fall under the category of pin-type locks.
5、Number-coded lock system
Install a sliding mechanism on the lock body, where the holes and slots are connected, allowing for movement and rotation. The number plate and rotating mechanism are also connected. The rotating mechanism is equipped with tooth-like or cam-like metal blades that can rotate and move. once the number is dialed, the lock will automatically open. This type of lock does not require a key.
Two. How to distinguish the types of locks.
The lock model can be identified by its appearance, such as number-coded locks, which have a clearly visible number dial on the lock body. For other lock models, the appearance may be similar, in which case we can consult the seller to determine the specific model.
