How to deal with the prompt that the security door is not closed properly

1. If the lock core of the security door has been damaged, it is mainly because it has been hit by gravity at ordinary times, or it has shifted loosely. We just need to tighten the lock cylinder. Of course, if the lock core has been seriously damaged, we can only replace the new lock core, remove the old lock core and install it in place, and basically close the security door.

2. If the security door has been deformed, it means that the hinge of the security door has been loosened, and the door cannot be closed if the door batten is uneven. First of all, we need to clean the hinges or hinges of the security door. Because of the long time, dust will accumulate on it, or some sundries will fall on it, which will also affect the effect of closing the door. You can also drop lubricating oil on the hinge to lubricate it.

3. If the security door is deformed, it will not open and close smoothly. You can tighten the expansion screws on both sides of the door frame and then widen the space between the door frames. Most of the deformation is because the screws at the hinge are loose. As long as the door is lifted and the screws are tightened, the problem of deformation can be solved.
