Anonymous users2024-01-24Most of the current security doors are new hinges (hinges), find some cooking oil or engine oil to point in, and then if the anti-lock is not on, it is a little deformed, you can see if the door plug is up and down, if it is.
Then when you lock the door, you can lock it with one hand and hold the upper door plug, and this kind of thing is very common!

It should be that the hinge part is astringent, and adding some lubricating oil to the transmission part of the lotus leaf should not ring.
Let's take a look at what the sound is, if it is a hinge, you can use some lubricating oil, it is also possible that there is something dirty inside, you can wash it with water first, and it may be that the rubber strip is loose, if the hinge is loose, the door leaf is small, and it is possible to squeeze into the rubber strip, there will be a sound, if it is the tongue of the lock, do not use lubricating oil, you can use pencil foam, the effect is very good, you can try.
Look at the door by yourself, and tighten it when the screws are loose. I'm looking for a master who repairs the door.,I hope it can help you.。。
If it is an abnormal noise from the door shaft, it is enough to add some lubricating oil. If you don't have lube, go to a children's toy store, there is a place that sells electric toy cars, and there are small tubes of lube that are sold.
Is there a shortage of oil, add some lubricating oil to the door pivot and try it.
