As shown in fig. 1 to 4, the present embodiment provides a partition door, which includes a door frame and a door body 1 rotatably connected to the door frame. The bottom of the door body 1 is provided with a first accommodating groove, and a first inner core 2 is fixedly arranged in the first accommodating groove. Correspondingly, the bottom of the door support is fixedly provided with a second inner core 3, and part of the second inner core 3 extends into the first accommodating groove and is matched with the first inner core 2.

Specifically, the first core 2 is provided with a first inclined surface 21, and the first inclined surface 21 is convexly provided with a first convex portion 22 and concavely provided with a first concave portion 23. The second core 3 is provided with a second inclined surface 31 corresponding to the first inclined surface 21. The second inclined surface 31 is provided with a second convex portion 32 and a second concave portion 33.

Under the action of gravity of the door body 1, the first inclined surface 21 is matched with the second inclined surface 31, meanwhile, the first convex part 22 on the first inclined surface 21 is clamped and abutted in the second concave part 33 on the second inclined surface 31, and the second convex part 32 on the second inclined surface 31 is clamped and abutted in the first concave part 23 on the first inclined surface 21, so that the first inner core 2 is fixed on the second inner core 3, and the door body 1 can be closed on the door bracket.

When the door body 1 is opened by external force rotation, the door body 1 drives the first inner core 2 to rotate, the first inclined surface 21 of the first inner core 2 rotates relative to the second inclined surface 31 of the second inner core 3, meanwhile, the first inner core 2 moves upwards, the first convex part 22 is separated from the second concave part 33, and the second convex part 32 is separated from the first concave part 23.

After removing external force, under the action of gravity of door body 1, door body 1 antiport resets, and first convex part 22 blocks again and supports in second concave part 33, and second convex part 32 blocks again and supports in first concave part 23, realizes the automatic closure of door body 1, and the use is laborsaving convenient, improves user and uses experience. The first inner core 2 is arranged in the first accommodating groove, and the second inner core 3 extends into the first accommodating groove to be matched with the first inner core 2, so that the hidden installation of the hinge structure is realized, and the attractiveness of the whole partition door is improved.

In the present embodiment, the first convex portion 22 and the second convex portion 32 have curved contour surfaces, and the first concave portion 23 and the second concave portion 33 have curved bottom surfaces. The first convex portion 22 has a contour surface continuous with the bottom surface of the first concave portion 23 via a transition surface. The profile surface of the second convex part 32 is connected with the bottom surface of the second concave part 33 through a transition curved surface, so that the rotating resistance of the first inner core 2 relative to the second inner core 3 is reduced, the external force required by opening the door is reduced, meanwhile, the abrasion between the first inner core 2 and the second inner core 3 is reduced, and the service life of the partition door is prolonged.

When the door body 1 is closed, the first convex portion 22 of the first inner core 2 is clamped and abutted against the second concave portion 33 of the second inner core 3, and the second convex portion 32 of the second inner core 3 is clamped and abutted against the first concave portion 23 of the first inner core 2. The door body 1 is driven to rotate, the door body 1 drives the first inner core 2 to rotate, the inclined surface of the first inner core 2 rotates along the second inclined surface 31 of the second inner core 3, meanwhile, the first inner core 2 and the door body 1 move upwards relative to the second inner core 3, and the first convex part 22 is separated from the second concave part 33 and rotates upwards along the second inclined surface 31. When the first projection 22 rotates to abut against the second projection 32, the door body 1 rotates to its maximum rotation angle. After that, the external force is removed, the door body 1 rotates in the direction under the action of the gravity of the door body 1, and meanwhile, the door body 1 and the first inner core 2 are downward relative to the second inner core 3 until the first convex portion 22 is re-clamped in the second concave portion 33, and the door body 1 is automatically closed.
