Heavy-duty concealed hinges are often used in heavy-duty revolving doors such as sealed doors and fire doors. They need to have strong support strength to ensure the normal rotation and opening and closing of the revolving door.
[0003] During the use of the existing hinge, due to the small contact area of the hinge joint and the heavy load-bearing factor, the hinge structure is very easy to wear, deform or make abnormal noises, and finally the door leaf connected to it sags and shakes.

DETAILED DESCRIPTION
[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] In this embodiment, refer to Figure 1-Figure 4 A high-stability load-bearing hinge structure is specifically implemented, including an auxiliary load-bearing mechanism and two sets of first hinges 1 and second hinges 2, wherein the two sets of first hinges 1 and second hinges 2 are respectively arranged at the upper and lower ends of the door leaf 9.
[0020] In actual use, the first hinge 1 and the second hinge 2 are respectively connected to the door frame 8 and the door leaf 9, and one end of the first hinge 1 and the second hinge 2 are hinged to each other, and the auxiliary load-bearing mechanism is arranged on one side of the second hinge 2, and the auxiliary load-bearing mechanism includes a ball structure 3 fixed to the lower end of the door leaf 9 and a supporting plate 4 for supporting the ball structure 3.
[0021] The utility model provides an auxiliary load-bearing mechanism, and the ball structure 3 cooperates with the support plate 4 to effectively increase the load-bearing capacity of the hinge, reduce the wear, deformation or abnormal noise of the hinge due to excessive load-bearing, and improve the service life and stability of the hinge.
[0022] The ball structure 3 includes a limit housing 3A and a support ball 3B rotatably disposed in the limit housing 3A, wherein the support ball 3B is rotatably disposed in the limit housing 3A, and one end of the support ball 3B protrudes from the limit housing 3A. The limit housing 3A is fixedly mounted on the lower end of the door leaf 9 by screws.
[0023] Furthermore, a vibration-damping gasket is arranged between the limit shell 3A and the door leaf 9, which is used to increase the stability of the installation and use of the ball structure 3, effectively reduce the vibration and noise generated by the door leaf 9 during the rotation process, and improve the vibration-damping performance and use comfort of the hinge.
[0024] Furthermore, the second hinge 2 is provided with a bearing portion 201 extending outward, and a plurality of threaded holes are evenly arranged on the bearing portion 201, and the bearing portion 201 is used to increase the contact area with the door leaf 9 and reduce the sagging of the door leaf 9. At the same time, the provision of the threaded holes also facilitates the maintenance and replacement of the hinge, and improves the practicality and convenience of the hinge.
[0025] Furthermore, the carrying portion 201 is arranged in a rectangular or L-shape.
[0026] Furthermore, the first hinge 1 is provided with a bearing 6 for cooperating with the second hinge 2. The provision of the bearing 6 makes the hinge rotate more steadily and smoothly, avoids problems such as jamming and shaking of the door leaf 9 during rotation, and improves the rotation performance and stability of the hinge.
[0027] Furthermore, a travel stopper 7 for limiting the rotation angle of the second hinge 2 is provided on one side of the first hinge 1 .
