If it still rings, it is recommended to find a manufacturer or seller to deal with it.

Anonymous users2024-01-23Most of the current security doors are new hinges (hinges), find some cooking oil or engine oil to point into the point, and then if the anti-lock is not on, it is a little deformed, you can see if the door plug is the kind that has up and down, if it is, then when locking the door, you can lock it with one hand on the upper door plug, this kind of thing is very common!
If it is three hinges, install the upper and lower hinges first, try to open and close well, and then install the middle hinge! If there is an abnormal noise, give the hinge some oil!!
I guess you're talking about loud doors when they close, right? It's very simple, go buy some leather strips (glue strips, glue, go back and stick to the place where the door frame fits the door leaf, and make sure it doesn't ring again!)

First of all, determine whether the hinges are ringing, or the door is rubbing the door frame! The general situation is the problem of the hinge (hinge) there, the door has been used for too long, and it is an old anti-theft door! It should be a dark hinge, try it with the oil on the tractor, if there is a bearing in it, it may be that the bearing is broken, this is difficult to replace!
1. Under normal circumstances, the anti-theft door hinge rings, and the grease can be directly applied to the hinge gap, which will slowly penetrate into the hinge. The rattling sound can be relieved, and the wax needs to be reapplied every six months. >>>More
