Working principle:

the worker first installs the first page 110 to one of the door leaf and the door frame, and then installs the mount 100 to the other of the door leaf and the door frame.

Referring to fig. 4, when the vertical position of the door leaf needs to be adjusted, the second screw is loosened, at this time, the mounting seat 100 and the first connecting piece 130 can move relatively, then the door leaf is driven by external force to move along the length direction of the first waist hole 210, after the door leaf is adjusted to a proper position, the second screw is screwed, at this time, the mounting seat 100 and the first connecting piece 130 are relatively fixed, and the vertical position of the door leaf can be positioned.

Referring to fig. 5, when the left and right positions of the door leaf need to be adjusted, the locking screw 200 and the first screw 250 are loosened, at this time, the leaf 230 and the clamping plate 240 loosen the second connecting piece 140, so that the second connecting piece 140 and the second leaf 120 can move relatively, then the door leaf is driven by external force to move along the length direction of the second waist hole 220, after the door leaf is adjusted to a proper position, the first screw 250 and the locking screw 200 are tightened, at this time, the second leaf 120 and the second connecting piece 140 are fixed relatively, and the left and right positions of the door leaf can be positioned.

It should be explained that, after the locking screw 200 is loosened, since the second connection member 140 and the first connection member 130 are connected through the adjustment member 150, the adjustment member 150 locks the second connection member 140 and the first connection member 130, so long as no external force is applied to screw the adjustment member 150, and after the locking screw 200 is tightened again, the distance between the second connection member 140 and the first connection member 130 is not changed with respect to the distance before the locking screw 200 is loosened, thereby enabling the hinge to not change the front and rear positions of the door when adjusting the left and right positions of the door.

Referring to fig. 6, when the front and rear positions of the door leaf need to be adjusted, the locking screw 200 is loosened first, at this time, the second connecting piece 140 and the first connecting piece 130 can move relatively, and then the adjusting piece 150 is screwed by external force, so that the adjusting piece 150 drives the second connecting piece 140 and the first connecting piece 130 to be close to or far away from each other, and accordingly, the hinge drives the door leaf to move back and forth, after the door leaf is adjusted to a proper position, the locking screw 200 is screwed, at this time, the second connecting piece 140 and the first connecting piece 130 are relatively fixed, and the front and rear positions of the door leaf can be positioned.

After the position adjustment of the door leaf is completed, the cover 270 is covered on the accommodating cavity 260 of the mounting seat 100, so that the components in the accommodating cavity 260 are shielded by the cover 270, and the effect of beautifying the appearance is achieved.
