How to install the spring of security door

The quality of security door is related to the safety of the whole family, and the quality of security door handle is very important in the quality of security door. How to install the spring of the security door handle? I have compiled some related materials for you today, hoping to help you.

The installation method of the anti-theft door handle spring is as follows

First, you should install small sleeves on two handles.

Second, you should aim a long iron piece on the inner handle at a small hole in the lock body.

Third, you should aim the square steel on the handle at the square hole on the handle.

Fourth, you should insert the external handle again, and finally you can screw it directly.

The most difficult thing is to align the square steel and the iron plate under the inner handle.

It's really easy to do these two things. By the way, there is a plastic cushion under the handle. You should put it on, too, lest you hurt the door.

Introduction of another method:

1. Insert a new handle and fasten the snap ring. At this point, it is basically completed. What is saved is to put it on the child. Put the handle back in its original position. It's good.

2. Be patient when installing, because there is a screw sleeve on the handle outside, and the screws must be aligned to be installed firmly. If you think it's expensive, you can find someone to help you hold the handle outside and install it slowly inside. Just aim at the last one and the other one will be easy to install.
