Working Principle
The lock adopts stable mechanical linkage structure to complete locking and unlocking operation:
-
Installation
-
The main lock body with integrated cylinder is fixed on cabinet frame by rear mounting screws.
-
Matching locking bolt is installed on the corresponding door panel.
-
-
Locking Process
-
Close the door and let the locking bolt enter the lock body groove.
-
Press the top pivoting latch down to clamp the locking bolt and complete preliminary closing.
-
Insert and turn the key, the internal bolt extends to lock the pivoting latch firmly, preventing prying and opening.
-
-
Unlocking Process
-
Turn the key reversely to retract the internal locking bolt.
-
Lift the pivoting latch to release the bolt, then open the door smoothly.
-
Operation Feature: The integrated cylinder directly locks the load-bearing latch. One-piece structure provides much better anti-pry and anti-theft performance than separate hasp and padlock solutions.
