Use of anti-theft door locks and maintenance precautions
Civil hardware accessories have been used for a long time, and many problems are prone to occur. In particular, the anti-theft door lock, this high-load operation of the parts, the service life is long, it is inevitable that there will be some trouble. It is often found that the damage of the security door locks in some users and friends' homes is often caused by improper use or maintenance.
The following points should be noted in the installation, use and maintenance of the anti-theft door lock:
1. Read the instructions carefully before installing the lock. Pay special attention to the fact that only the end with the fuse can be removed, and the end of the key should never be removed.
2, the installation of the door lock and the distance between the security door can not be less than 80mm, otherwise the security door will be locked on the door of the door, can not close the security door, can not play the role of anti-theft.
3, try not to add any oil in the lock core, if you want to lubricate should be painted with graphite or pencil lead.
4, the security door lock tongue and the surrounding "world lock" rod. It is necessary to add motor oil motorcycles, automobile machinery oil, sewing machine oil, etc. within three months, especially in wet and rainy days. (Note that any vegetable oil, including arowana oil, etc., cannot be used. Because it contains vegetable gum, the human body can absorb it and the machinery can not absorb it. After the water in the oil is dry, the vegetable glue is left, and the viscosity increases, which makes the security door more inflexible. ).
5, newly renovated friends, should be attached to the security door around the protective layer such as newspapers, so as not to cause a large amount of dust caused by home adsorption on the security door bar to reduce the service life. And after the decoration is completed, check whether there are decoration residues in the surrounding of the door frame to remove the oil and add the oil.
6. Check the matching clearance between the lock body and the lock plate. The fit between the lock tongue and the lock plate hole is appropriate. The matching clearance between the door and the door frame is 1.5mm-2.5mm. If changes are found, adjust the position of the hinge or lock plate on the door. At the same time, pay attention to the shrinkage and thermal expansion caused by the weather (wet spring, dry in winter) to ensure the clearance between the door and the door frame, the lock body and the lock plate is reasonable, so as to ensure the smooth use of the lock.
7. Locking in the process of opening and closing the door on weekdays, it is best to hold the handle and screw the locking tongue into the lock body. After closing the door, let go of the hand, do not force the door, otherwise it will reduce the service life.
8. Do not wipe the lock body and handle with a damp cloth, because some metal locks will rust; alloy locks will wear away the coating and lose the aesthetic effect.
