Adjustment method of door gap of security door:
Inner door
Close the door first and look at the gap around the door leaf from the inside. As you said, the gap on the hinge side is large. Just adjust the gap. If there is no gap around, it is the reason for installation or manufacturer.
Outside door
The method is as follows:
When there is a gap between the door crack of the security door, first check the reason why the door is tight. Open the door and shake the door frame hard to see if the expansion screw between the door frame and the wall is loose. If it is loose, it is difficult to repair. If there is no problem between the door frame and the wall, you can adjust the hinge. Method 1: loosen the five Winkle of the hinge basically, and then turn the eccentric screw in the middle to the gap you think is appropriate. If you think the gap between them is not enough, just plug something between the door panel and the door frame. After adjusting it, pull it out. Try a few more times to adjust it. Finally, tighten the screws. Method 2: Concealed hinges has 5 screws. The door has been used for a long time and is a little drooping. Squeezing the lower door frame makes a creaking sound. You need to adjust the hinge and push the lower part of the door out a little.

2. Adjust the hinge below. The hinge above does not need to be moved. Loosen 4 winkle with inner hexagon, and then loosen the big nut with a wrench. In the middle of the big nut is an eccentric screw. You can adjust the open crotch distance of the hinge by gently rotating it with a word screwdriver.
3. Then lock 4 Winkle and try to close the door. If it feels suitable for several times, lock the middle nut and tighten all screws further.
The following are some standard references for clearance:
1. The gap between the door crack of the security door is: the standard stipulates that "the gap between the door leaf and the hinge side of the door frame should not be greater than 2mm, and the gap between the opening side of the door and the door frame faying surface should not be greater than 3mm in the closing state." Then: It is common that the width of the door frame minus the width of the door leaf should not be greater than 2+3=5mm. Mother-son type the width of the security door frame minus the width of the female door leaf and the width of the sub door leaf should not be greater than 2+3 + 7mm.
2. The actual data measured by the installation workers of the manufacturer are: the width of the door frame is 1066mm, the width of the female door leaf (748) and the width of the sub door leaf (300) is 1048mm. Mother-son type the width of the security door frame minus the width of the female door leaf and the width of the sub door leaf is 1066-1048=18mm, the actual gap is larger than the gap specified in the Standard:(18-7)/7=157%.
