[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As shown in the attached figures, this utility model discloses a hinged door rotating structure, including a door leaf 1 and a door frame 2. The door leaf 1 has a side post 11 on one side, and the side post 11 is rotatably connected to the door frame 2 through a rotating structure. The rotating structure includes a first axle pin 101, a second axle pin 102, an annular portion 104, and a bushing 103. The first axle pin 101 and the annular portion 104 are respectively disposed at the upper and lower ends of the side post 11. Referring to the figure, the first axle pin 101 protrudes from the upper end of the side post 11, and the annular portion 104 is disposed inside the lower end of the side post 11. The door frame 2 includes a top beam 21 and a bottom beam 22. The bushing 103 is disposed inside the top beam 21 and is rotatably connected to the first axle pin 101. The second axle pin 102 is disposed on the upper side of the bottom beam 22 and is rotatably connected to the annular portion 104. The top beam 21 has an inverted U-shaped cross-section with a downward-facing groove, and the bushing 103 is disposed in the groove.

[0024] This utility model discloses a swing door rotating structure. By setting a side post 11 on one side of the door leaf 1, and setting a first axle pin 101 and an annular part 104 at both ends of the side post 11, the first axle pin 101 is hidden in the top beam 21 and is rotatably connected to the bushing 103 of the top beam 21. The second axle pin 102 of the bottom beam 22 is rotatably set inside the annular part 104, thereby realizing the swing opening of the door leaf 1 relative to the door frame 2. At the same time, the rotating structure is hidden in the door frame 2 and the side post 11 of the door leaf 1, which enhances the aesthetics of the swing door and better protects the rotating structure.

[0025] Specifically, the upper end of the side post 11 is provided with an upper seal 13 and a lower seal 14, respectively. Both the upper seal 13 and the lower seal 14 are fixedly connected to the side post 11. Specifically, the side post 11 has a cavity. The upper cover plate 131 and the lower cover plate 141 are provided with plugs 142 on the side facing the cavity. The plugs 142 are inserted into the cavity to realize the installation of the upper seal 13 / lower seal 14 and the side post 11. Screws or glue can be used for further fixing. In addition, it should be noted that one side of the side post 11 is provided with an installation groove for installing the door panel 12. The door panel 12 can be made of materials such as glass or wood. The upper seal 13 includes an upper cover plate 131, and the first shaft pin 101 is disposed on the upper side of the upper cover plate 131. The lower seal 14 includes a lower cover plate 141, and the annular portion 104 is disposed on the upper side of the lower cover plate 141. When the side post 11 and the lower seal 14 are connected, the annular portion 104 is located inside the side post 11. The lower cover plate 141 is provided with a through hole 1040 corresponding to the annular portion 104. The through hole 1040 is used for the second shaft pin 102 to extend to the upper part of the lower cover plate 141.

[0026] Specifically, the first pin 101, the second pin 102, the bushing 103, and the annular portion 104 are all arranged on the same axis to ensure that the rotation center of the side post 11 remains vertical.

[0027] Specifically, the first axle pin 101 and the bushing 103 are respectively provided with a sector-shaped protrusion 111 and a sector-shaped protrusion 112 on their facing sides. The sector-shaped protrusion 111 and the sector-shaped protrusion 112 are symmetrically arranged about the axis of the first axle pin 101 and are arranged along the length of the door leaf 1. The sector-shaped protrusion 111 and the sector-shaped protrusion 112 limit the opening angle of the door leaf 1, preventing the door leaf 1 from colliding with the door frame 2 if it is opened too wide, and also providing protection. The rotating structure has a rounded central angle for both sector-shaped protrusion 111 (a) and sector-shaped protrusion 112 (b). When the door leaf 1 opens outwards, the first pivot pin 101 rotates, meaning sector-shaped protrusion 111 (a) rotates until it stops against sector-shaped protrusion 112 (b). This is the maximum outward opening angle. When the door leaf 1 opens inwards, the first pivot pin 101 rotates in the opposite direction, meaning the other side of sector-shaped protrusion 111 (a) abuts against sector-shaped protrusion 112 (b). This is the maximum inward opening angle. By limiting the opening angle, the door leaf 1 is prevented from colliding, thus protecting it.

[0028] Specifically, the top beam 21 is equipped with an upper connector 23, the bottom beam 22 is equipped with a lower connector 24, the bushing 103 is located on the lower side of the upper connector 23, and the second pin 102 is located on the upper side of the lower connector 24. Both the upper connector 23 and the lower connector 24 are provided with snap-fit ​​grooves 240. The top beam 21 and the bottom beam 22 are respectively snapped into the corresponding snap-fit ​​grooves 240. The upper connector 23 / lower connector 24 are installed on the top beam 21 and the bottom beam 22 through the snap-fit ​​grooves 240, thereby fixing the upper connector 23 and the lower connector 24. The second pin 102 and the bushing 103 act as fixed ends when the door leaf 1 rotates. The bushing 103 is located at the bottom of the snap-fit ​​groove 240 of the upper connector 23, and the other snap-fit ​​groove 240 is located on the lower side of the lower connector 24.

[0029] As shown in the figure, the door frame 2 includes a frame post 203. The frame post 203 contacts the side of the door leaf 1 away from the side post 11. The frame post 203 and the side post 11 have the same shape. In order to achieve a visual effect of left and right symmetry, a frame post 203 with the same shape as the side post 11 is set on one side of the door frame 2. The frame post 203 and the side post 11 can adopt the shape of Roman columns as shown in the figure. Further extending, as shown in the figure, the hinged door can also have a fixed door panel 12 set on one or both sides of the door leaf 1.

[0030] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
