DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0030] Embodiment:

[0031] With reference to Figures 1-6 , the multi-segment force hinge comprises a hinge body 1 and a hinge cup 2, the hinge body 1 is fixedly connected with a hinge inner part 6, the hinge inner part 6 is rotatably connected with a supporting arm 4, the hinge body 1 is connected with the hinge cup 2 through the supporting arm 4, and the multi-segment force hinge further comprises:

[0032] a hinge arm 3 rotatably connected to the hinge inner part 6;

[0033] a cam arm 1021 rotatably connected to the hinge inner part 6;

[0034] an arc rotating shaft 1032 rotatably connected to the hinge inner part 6;

[0035] a spring 103 fixedly connected to the arc rotating shaft 1032;

[0036] a spring head 1031 fixedly connected to the spring 103;

[0037] the cam arm 1021 abuts against the spring head 1031.

[0038] the hinge arm 3 is rotatably connected with a wear-resistant wheel 301, and the wear-resistant wheel 301 abuts against the cam arm 1021.

[0039] the hinge body 1 is rotatably connected with a vortex adjusting screw 5, the hinge inner part 6 is fixedly connected with a rack 105, and the vortex adjusting screw 5 is matched with the rack 105.

[0040] With reference to Figures 3-5 In use, the staff can adjust the hinge inner part 6 by rotating the vortex adjusting screw 5. When the vortex adjusting screw 5 is rotated, the rotation of the vortex adjusting screw 5 can drive the rack 105 to move forward and backward, thereby driving the hinge inner part 6 to move forward and backward, thereby completing the adjustment.

[0041] It should be noted that when the vortex adjusting screw 5 is not rotated, the vortex adjusting screw 5 has a locking effect on the rack 105 to ensure the stability of the hinge inner part 6.

[0042] The first rotating shaft 101 is rotatably connected to the hinge inner part 6, and the first rotating shaft 101 is fixedly connected to the hinge arm 3.

[0043] The second rotating shaft 102 is rotatably connected to the hinge inner part 6, and the second rotating shaft 102 is fixedly connected to the cam arm 1021.

[0045] With reference to Figures 1-6 In use, the hinge body 1 and the hinge cup 2 are installed on two bases that need to be rotated, such as a door and a door frame.

[0046] When the door needs to be rotated, the hinge cup 2 is rotated counterclockwise to the hinge body 1 with the hinge body 1 as a reference point, and at this time the hinge arm 3 is rotated clockwise around the first rotating shaft 101, so that the supporting arm 4 is rotated to be attached to the hinge cup 2.

[0047] When the hinge cup 2 is opened, the wear-resistant wheel 301 on the hinge arm 3 extrudes the cam arm 1021, and the cam arm 1021 extrudes the spring head 1031, at this time the spring head 1031 is rotated around the circular arc rotating shaft 1032, and at this time the spring 103 is compressed, and at the same time the hinge arm 3 is rotated, the hinge arm 3 abuts against the buffer damping 104, so that the hinge arm 3 is stably rotated.

[0048] When the hinge cup 2 is closed, the hinge arm 3 is reversely rotated, and the wear-resistant wheel 301 on the hinge arm 3 reversely rotates a certain angle to extrude the cam arm 1021, thereby releasing the limiting state of the cam arm 1021, at this time the spring 103 is released, the spring 103 drives the spring head 1031 to move, thereby pushing the cam arm 1021 to rotate around the second rotating shaft 102, the cam arm 1021 pushes the hinge arm 3 to rotate, thereby driving the hinge cup 2 to close.

[0049] Through the cam arm 1021 added in the device, when the hinged cup 2 is closed, the effect of soft buffering over-closing can be achieved, and through the cooperation of the worm adjusting screw 5 and the rack 105 arranged in the device, the cooperation precision between the hinged cup 2 and the hinge body 1 can be conveniently adjusted, the cooperation stability of the worm adjusting screw 5 and the rack 105 is higher, and the problem that the cam adjusting screw is prone to position deviation in the prior art is solved.
