[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0021] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0022] Reference Figure 1-4 A combination hinge includes a symmetrical first left hinge 1 and a first right hinge 2, and a symmetrical second left hinge 3 and a second right hinge 4. The first left hinge 1 and the first right hinge 2 are installed at the bottom or top of the door frame when in use, and the second left hinge 3 and the second right hinge 4 are installed on the side of the door frame when in use. Through different combination methods, it can be installed in a variety of occasions, greatly improving the scope of application.

[0023] Both the first left hinge 1 and the first right hinge 2 include a first fixed seat 10. A first rotating seat 5 is rotatably mounted on the first fixed seat 10. A first rotating shaft 6 is provided on the first fixed seat 10. The first rotating seat 5 is provided with a first through hole 7 corresponding to the first rotating shaft 6. The first rotating shaft 6 passes through the first through hole 7. A first limiting ring 8 is provided on the first rotating shaft 6. The first rotating seat 5 is provided with a first mounting hole 9 corresponding to the first limiting ring 8. A first limiting pin is installed in the first mounting hole 9. The end of the first limiting pin is inserted into the first limiting ring 8.

[0024] Both the second left hinge 3 and the second right hinge 4 include a second fixed seat 11. A second rotating seat 12 is rotatably mounted on the second fixed seat 11. The second fixed seat 11 includes a fixed part 13 and a connecting part 14 (used to adjust the door gap size, which is prior art) that moves in the front-back direction of the fixed part 13. The second rotating seat 12 is rotatably mounted on the connecting part 14. A second rotating shaft 15 is provided on the connecting part 14. The second rotating seat 12 is provided with a second through hole 16 corresponding to the second rotating shaft 15. The second rotating shaft 15 passes through the second through hole 16. A second limiting ring 17 is provided on the second rotating shaft 15. The second rotating seat 12 is provided with a second mounting hole 18 corresponding to the second limiting ring 17. A second limiting pin is installed in the second mounting hole 18. The end of the second limiting pin is inserted into the second limiting ring 17.

[0025] The hinge's fixed seat and rotating seat are fixed by a pin, which is simple in structure and easy to install.

[0026] The center lines of the first rotating shaft 6 and the second rotating shaft 15 are on the same straight line, with a high degree of concentricity, so there will be no abnormal noise when opening and closing the door, as is the case with conventional products on the market.

[0027] Method 1 is as follows: use the first left hinge 1 as the bottom hinge and the first right hinge 2 as the top hinge. In this method, the two first fixed seats 10 are installed at the top and bottom of the door frame, respectively, while the first rotating seat 5 is installed on the side of the door. This method is suitable for situations where the gap between the door and the door frame is small. Depending on the direction of opening the door, the positions of the first left hinge 1 and the first right hinge 2 can be replaced.

[0028] Method 2 is as follows: use the second left hinge 3 as the upper side hinge and the second right hinge 4 as the lower side hinge. In this method, the two second fixed seats 11 are installed on the side of the door frame, and the second rotating seat 12 is installed on the side of the door. Similarly, depending on the opening direction, the positions of the second left hinge 3 and the second right hinge 4 can be replaced.

[0029] Method 3 is as follows: the first left hinge 1 is used as the bottom hinge, and the second left hinge 3 is used as the top side hinge. In this method, the first fixed seat 10 is installed at the bottom of the door frame, the first rotating seat 5 is installed on the side of the door, the second fixed seat 11 is installed on the side of the door frame, and the second rotating seat 12 is installed on the side of the door. This method is suitable for doors with a certain weight. The first left hinge 1 provides support and improves the overall support effect of the hinge. Similarly, depending on the opening direction, the positions of the first left hinge 1, the first right hinge 2, the second left hinge 3, and the second right hinge 4 can be replaced.

[0030] When in use, this product has corresponding receiving cavities on the door and door frame. After the hinges are installed, they are hidden inside and not exposed, which improves the overall appearance of the door.

[0031] This product is made using precision casting technology, which gives it excellent load-bearing capacity and prevents sagging issues common in other products on the market.
