Anti-theft door maintenance method
1. When the key cannot be completely inserted into the lock hole when opening the door, if it is in winter, first check whether the key hole is frozen; In other seasons, check whether there are foreign objects in the keyhole.
2. When you hear the metal rubbing sound of the switch door, you can try dropping a little lubricating oil on the hinge of the security door. If it fails, you can find a professional repairman.
3. The burglar-proof door lock has become the most prone to problems on the burglar-proof door, so it is very necessary to maintain the lock. The main problem of the burglar-proof door lock is that it is very difficult to insert or remove the key after a period of use. In this case, you must not lubricate the door with oil. Using oil will make the door unable to open, which is counterproductive. You should grind the key with a pencil several times or blow it into the keyhole with pencil foam to lubricate the key.
4. When installing the security door, cement should be carefully filled to effectively combine the door frame with the wall, so that the door body and the door frame can be reasonably matched and used for a long time without worrying about deformation.
5. In severe cold areas, the problem of "wintering" the security door is also very important, because the indoor and outdoor temperature difference in severe cold areas is very large, so it is very easy for the lock core of the security door to get wet and then freeze when hot and cold water flows. To avoid this situation, before the arrival of winter, it is necessary to drop two drops of antifreeze engine oil in the lock core, and then use gasoline or diesel to clean it in winter. Do not use vegetable oil as lubricant for lock cylinder.
6. When the security door with the lock is closed, it is difficult to close the door with loud noise. The difficulty of closing the door with the lock is mainly due to the astringency of the lock tongue. If you grind some lead or soap on the inclined surface of the lock tongue, it will play a role in lubrication, and it will be much easier to close the door (if you use oil, you will accidentally stick to your clothes). Note that this method of security door deformation is invalid.
Maintenance method of anti-theft door
1. Door leaf maintenance: always wipe the dirt on the door leaf with a clean soft cloth, and pay attention to ensuring the dryness of the security door to avoid sun and rain. Composite plastic steel plate products should protect the composite plastic film to avoid cutting; Plastic-sprayed steel plate products avoid water or other dirt or corrosive substances that are difficult to remove, so as to prolong the service life of security doors. It is recommended not to tear off the protective film on the composite plastic board before the decoration is completed, or cover the plastic-sprayed board with a layer of film.
2. Door frame maintenance: The door frame of the security door is made of plastic-sprayed materials, and the maintenance method is the same as that of the plastic-sprayed door leaf. However, after installation, the gap between the door frame and the wall should be filled with cement as soon as possible to avoid losses caused by the destruction of expansion screws; Regularly remove the dust deposited in the bolt of the cannon lock below.
3, lock maintenance: regularly blow a little pencil lead powder into the lock core of the security door to ensure that the lock rotates freely; Regularly inject a little clean oil into the mechanical transmission of the cannon lock, and regularly wipe the lock handle or luxury handle with a soft cloth.
4. Maintenance of doorbell: Press the button lightly when using the doorbell, replace the battery when the power is insufficient, and take out the battery if you need to leave home for a long time.
5. Maintenance of door mirrors: Wipe them regularly with a soft cloth to avoid contamination by oil or corrosive substances, damp, high temperature or direct sunlight.
