The positioning structure 3 is used to linearly move the hinge leaf 21 along the first direction Y or the second direction X to adjust the relative position of the door frame 11 and the door 12.

The specific use of the positioning structure 3 is as follows: as shown in fig. 3 and 8, the lower locking screw 42 of the lower positioning assembly 32 is loosened by a screwdriver or other tools, so that the lower sliding platform 321 can move linearly along the first direction Y by the cooperation of the lower locking screw 42 and the lower long guide hole 322, and after the displacement adjustment in the first direction Y is completed, the lower locking screw 42 is locked again to lock the lower sliding platform 321 on the door frame 11, so that the lower sliding platform 321 cannot move. Then, the lower fixing screw 46 of the lower positioning assembly 32 is loosened to enable the lower slider 325 to slide in the lower chute 323 along the second direction X, and then the lower adjusting screw 44 is rotated to adjust the displacement distance of the lower slider 325. since the lower combining bolt 324 is assembled on the lower slider 325, the displacement distance of the lower combining bolt 324 is equally adjusted, after the displacement adjustment in the second direction X is completed, the lower fixing screw 46 is re-locked to disable the lower slider 325 from moving, and thus the lower combining bolt 324 cannot move linearly along the second direction X. In this way, the relative positions of the door frame 11 and the door 12 can be adjusted because the hinge leaf 21 is clamped by the lower coupling bolt 324 and the hinge axis connecting plate 22 is fixedly connected to the hinge leaf 21 and the door 12 side, respectively. The adjustment of the upper positioning element 31 is the same as that of the lower positioning element 32, and therefore, the detailed description thereof is omitted.

In summary, in order to make the present invention more advanced and practical, the features of the present invention are described as follows:

1. the hidden hinge structure with special design is used as the main component for combining the door frame and the door leaf.

2. The hinge structure is arranged in the containing groove of the door frame, and is fixedly connected with the hinge fixing part of the hinge leaf by the hinge fixing part of the hinge axis connecting plate and fixedly connected with the door leaf fixing part of the hinge axis connecting plate at one side of the door leaf to form a specially designed rotating axis, so that the turning radius of opening and closing the door leaf can be shortened, and the gap between doors can be effectively reduced.

3. One side of the door leaf is combined with the arc-shaped strip (hinge leaf) by using the L-shaped strip (hinge axis connecting plate), and the L-shaped strip can be customized along with the thickness of the door leaf, so that the weight of the door leaf is effectively borne.

4. The upper combining bolt of the upper positioning assembly and the lower combining bolt of the lower positioning assembly respectively adopt a ball bearing and a thrust bearing, and through the design of the bearing and the steel ball, the rotating friction force of the hinge leaf is effectively reduced, the force for opening and closing the door leaf is effectively reduced, and the silencing effect during closing is achieved.

5. When the door is closed, the hinge structure is different from the traditional hinge structure, and the problem that the axis is exposed is solved.

6. The relative position of the door leaf and the door frame can be adjusted through the positioning structure, the gap between the door leaf and the door frame is reduced, light transmission can be prevented, and peeping can be avoided.

7. The axis of the hinge leaf of the hinge structure is arranged in the containing groove of the door frame, so that when the door leaf is opened, the door leaf is parallel to the door frame, and the door leaf can not be collided when a wheelchair or a sickbed or other articles pass through the door. The door frame can improve the problem that the door leaf protrudes out of the door frame when the door is opened generally, so that people or articles are easy to collide with the door leaf when passing, and damage or injury is caused.

8. The relative position of door leaf and door frame can be adjusted through location structure, make the hinge leaf drive the door leaf along first direction Y displacement (can be regarded as the back-and-forth movement), or along second direction X displacement (can be regarded as moving about, move towards the door lock side or towards hinge side promptly), with the relative position of adjustment door leaf and door frame, and the produced position deviation of correction door body when the installation, because the door body has the deviation when the installation, for example the door leaf hangs down, or the closure between door frame and the door leaf is not good.

9. The hinge structure is matched with the positioning structure, and can still be adjusted through the positioning structure after the hinge structure is installed, so that the repairing time and cost can be reduced.
