It is necessary to install the door lock when decorating, and the door lock must be installed carefully. If the installation size is calculated incorrectly and the installation size is inappropriate, the most serious consequence is to replace the whole door. The quality of the door lock is very important. If the door lock is broken during installation, it will be difficult to replace it later. These must be paid attention to when installing the door. There are many detailed rules for installing door locks. Let's talk about the precautions for installing door locks.

1. When you buy a door lock, you will attach an opening diagram and precautions for unlocking. Please read the door lock carefully before installing it.

The thickness of the door body where the door lock needs to be installed is normally 4-5.5 cm, and the width of the internal solid part in the door frame area is greater than 1 1 cm. If there is a door lock with hollow structure in this range, it will not be installed, so you should also pay attention to these when customizing the door.

Before installation, check whether the accessories of the door lock are complete, and try whether it can be unlocked normally and smoothly with each matching key.

2. When installing the door lock, first make an opening on the door body, and the size of the opening should be measured strictly according to the size of the opening diagram.

The positioning of the opening should also be carried out according to the standard of the opening diagram. If the opening is too small, the door lock is not easy to install. If the electronic lock with circuit board is forcibly installed at a small opening, it will easily lead to the deformation of the circuit board, and the door lock will not work normally after installation.

If the opening is too big, the lock body part of the door lock cannot completely cover the hole position, and the appearance will be unsightly.

3. The most important thing to pay attention to when installing the door lock is that the door lock should be consistent with the opening direction of the door. After the lock cylinder hole is opened, the lock cylinder should be inserted into the hole to check whether the size is appropriate. When installing the lock core, the tightness between the lock core and the hole must be kept at a natural level.

When installing the lock core, adjust the position, press the inclined tongue in and release it, so that the inclined tongue can be ejected smoothly. After checking that there is no problem, tighten the screw to fix the lock cylinder.

4. After the lock cylinder is installed, fix the door lock on the lock cylinder. When installing the door lock, do not use a wet cloth to remove the dust in the lock, otherwise it will easily rust the lock.

Install the front panel and the rear panel of the door lock, and ensure that the door lock handle hole of the front panel is aligned with the square shaft and the lock cylinder hole. The door lock handle of the rear panel is aligned with the square steel, and the small square steel is aligned with the lock cylinder hole.

Check whether the door lock handle is used smoothly after installation. Whether the indoor rotary button can be used normally and rotated to the normal position.

Precautions for door lock installation In addition to the above, when installing a door lock, you must pay attention to the opening direction of the door, whether it is outward or inward, and the direction of the handle should be correct. Generally, the handle of the back door of an indoor door will touch the wall, so it is best to install a door suction to prevent damage to the wall.
