Anonymous users2024-01-22The lock needs to be lubricated and maintained frequently, otherwise it will be difficult to open, rust, or even screw the key, or the internal lock block will be stuck and cannot be opened.
Most of the well-known lock factories such as Escola use fully synthetic lock lubricants from Hotolube or Kluber. Fully synthetic base oil production, clear and transparent, colorless and odorless. It is resistant to low temperature and does not contaminate with dust.
Tao is full of 30 ml needle-nosed small oil bottles, drop a few drops, easy to use. The maintenance interval is six months.
Mineral oil should not be used because it is highly viscous and tends to get dirty. It is also not suitable to use pencil end or black graphite lubrication, which cannot lubricate the internal parts, and there will be heavy metal and color pollution.

The deadbolt and the lock plate of the door frame are rubbed between Fankai, you can knock on the lock tab, it is very simple to judge, after closing, do not use the key to regret the lock, live in the inner side of the house, push the door hard, if there is no shaking and gap, that is, the gap state is too small, the lock tongue is too small, add some oil, and then the lock plate knocks.
It must be that the screws of the door master were not tightened when the door was installed, which caused the door to sag now, and the lock did not match the lock point box. That's why it's so hard to open the door. I suggest that you still find the store when you bought the store before, and ask the master in the store to come back to the door to debug.
Draw a candle or pencil lead powder on the deadtongue and it will be smooth.
It's hard to buy, so you might as well go to the market and buy a doorbell board so that you can do it yourself.
How can the anti-theft door press the glass, it's a cat's eye, right?
