How does a cam lock work?
The following points should be paid attention to when using the tongue-turning lock:
(1) When opening and closing doors in peacetime, it is necessary to turn the lock tongue into the lock body and release the hand after closing the door. Avoid hitting the door lock with force at ordinary times, otherwise it will reduce the service life.
(2) In the process of using, if the key is not inserted smoothly, a little graphite powder can be added into the lock slot to make the key inserted smoothly. However, it should be noted that oil can not be added to the lock core groove to lubricate, otherwise the grease sticks to the marble spring, leading to the lock head can not be opened.
(3) In use, it is necessary to regularly check the fit clearance between the lock body and the locking plate, and the high and low fit between the lock tongue and the hole of the locking plate, so as to ensure the proper distance between the two. If the spacing is found to vary, the position of the hinge or locking plate on the lock door can be adjusted.
