"Then:

It is not uncommon to see the width of the door frame minus the width of the door leaf should not be greater than 2 + 3 = 5mm. The width of the door frame of the mother-child anti-theft door minus the width of the mother door leaf and the width of the child door leaf should not be greater than 2+3+7mm.

2.The actual data measured by the installers of the manufacturer is: the width of the door frame is 1066mm, the width of the mother door leaf (748) and the width of the sub-door leaf (300) is 1048mm.

The width of the door frame of the mother-child security door minus the width of the mother door leaf and the width of the sub-door leaf is 1066-1048 = 18mm, and the actual clearance is larger than the gap specified in the standard: (18-7) 7 = 157%.

How to adjust this, what is the function of the two screws?

The functions of these two groups of good megalead screws are: 1. It plays the role of connecting the two hinges together. It can also be used to separate the two.

2. Locate the door leaf to prevent the door leaf from sagging for a long time. It is also possible to ** the gap between the door leaf and the door frame.

The pro hinge adjustment method has been sent to you too.

You can refer to it.

You can use a sealing strip or adjust the keyhole metal plate of the door frame.

It may be caused by the excessive gap between the deadbolt and the door frame, in this case, you can buy some sealing strips and stick them around the security door, and there will generally be no clanging sound.

If the deadbolt position is incorrectly cut, or the reserved position is too large, it will also cause noise, just adjust the position of the keyhole metal plate on the door frame to the appropriate condition.

Because the door is opened and closed with too much force, the rubber strip cracks, or the sealant is aging and hardening, resulting in leakage of the wind, at this time, the windproof rubber strip can be replaced and filled, and the rubber strip can be used to fill another layer after the filling is completed, so that the problem of air leakage of the anti-theft door can be basically solved.

Because the hinge is used for a long time, it will loosen and deform and sink, which will eventually lead to the door gap becoming larger.

How to increase sound insulation if the door is not tight:

1. A layer of soundproof board is wrapped outside the door panel, mineral wool sound-absorbing board can be used, other soundproof materials can also be used, and you can also go to the decoration store to consult. If you don't think it's okay to install soundproofing materials on one side, you can wrap soundproofing imitation panels and sponges on both sides.

2. Sealing of door cracks. Fill the gap of the door with sponge or other soundproofing materials, and put a little more soundproofing layer on the door panel to make the door and door frame fit tightly.

3. In this way, your door can achieve a better sound insulation effect, which is much more comfortable than wearing earplugs. Of course, it is recommended that you go to a nearby decoration store to inquire, inquire clearly, buy the materials yourself, find someone or do it yourself.

Please be clear what the hinge is. There are many varieties of hinges. It's best to have pictures if you don't understand.
