Security door maintenance tips

Regularly add a little lubricating grease to the mechanical rotating parts such as the hinge, lock tongue and latch of the anti-theft door to keep the lubrication and keep the flexible opening and closing of the anti-theft door and its locks. The tightness of the expansion bolts used in the installation of the door frame and the wall and door frame should be checked regularly to avoid potential safety hazards.

The screws on the hinges of the door body should be reinforced every three months to avoid the door sagging after the screws are loosened, so that it is difficult to open the door due to friction with the door frame. In addition, the screws on the lock plate and handle should be reinforced regularly, but never remove the lock without permission. Consumers are not professionals, and it is inevitable that there will be gaps, errors or poor coordination of parts after the lock is removed and then installed, which may directly lead to the failure of the safety door lock and other problems.

In addition, the pencil end lubrication should be added to the cylinder regularly to make the key insert and unplugging smoother, but it should not be lubricated with grease. If grease is dripped into the hole, it will mix with the iron filings caused by the key rubbing inside the cylinder, and the entire cylinder will be blocked within a month.

There may be several reasons why the security door at home cannot be locked:

1.There may be a key inserted in the keyhole on the inside of the door lock, resulting in the outer key not being inserted to the end, so the outer key cannot be rotated and the door cannot be opened.

2.There may be small pieces of advertising paper stuffed in the door lock, resulting in too tight door gaps, deformed door leaves, and so on.

At this time, you can find a flat screwdriver, pull the protruding screw through the crack of the door, and pull it back in.

3. If the lock is stuck with a foreign object, it is difficult to twist the handle or key open, if the door is opened outward, the door can be pulled inward; If the door is open inward, you can push the door outward with force, which reduces the jamming force and allows the door to be easily twisted.

The reason why the door lock won't open.

1. Someone in the door (such as children and the elderly) accidentally hit the safety bolt and will not open the safety bolt, causing the person outside to unlock the lock with a key, and the door cannot be opened because the door lock is hit with the safety bolt.

2. The user usually has the habit of lifting the safety bolt at home, and when opening the door, he forgot it for a while, so when he closed the door, he forced the door to close without shrinking.

3. It is due to the loosening of the safety bolt button in the door, and the force is too strong when closing the door, which shocks the safety bolt down, and the lock cylinder can be rotated with the original key, but the door cannot be opened.

4. The lock body is stuck by foreign objects or the lock body is damaged due to the quality of the lock body, and there is a situation that you can't get in and out.
