How to deal with a broken handle in the hardware accessories of doors and windows?

In our daily lives, I believe many people have encountered situations where the door and window tongue gets stuck or the handle cannot rotate. If we suddenly encounter such problems, we need to know the specific reason for not being able to open it, and then prescribe the right medicine. Below, the hardware manufacturer of Dongge doors and windows will analyze the reasons why the handle cannot be opened and provide solutions!

For situations where a malfunction cannot be opened and solutions:

1. There is a problem with the lock body, and it cannot rotate when the handle is pressed down. So the oblique tongue cannot rebound. The solution is to open the panel and check if the insertion rod is working properly. If it is, it can be determined that it is a lock body problem.

2. Another possibility is that the slanted tongue is stuck at the baffle, which is actually a problem with the lock body, but it can be repaired. Try using a screwdriver to remove it. If it doesn't work, then the only option is to replace the lock body.

3. There is also a third possibility, of course, which has a very low probability, which is that the lock cylinder has a problem. When twisted open, the lock cylinder cannot automatically return due to being too tight, causing the lock body to rotate and not rebound, and the inclined tongue cannot be extended. Try twisting the key a few more times to see if it works. The probability of this is very low, try the first two first.

The solution for rust locks in door and window hardware accessories that cannot be opened:

1. Cut some pencil lead powder or graphite powder with a pencil sharpener, inject it into the lock hole, and then insert the key into the lock hole and slowly rotate it to open the rust lock.

2. Immerse the silver in kerosene or gasoline, take it out and wipe off the oil after a while, then drop a few drops of sewing machine oil or vegetable oil into the lock hole, insert the key into the lock hole and slowly turn it, usually it can also open the rust lock.
