In addition, for the purpose of simplifying the drawings, some conventional structures and components will be shown in a simple schematic manner in the drawings.

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 , the buffer structure of the door hinge of the present utility model includes a first mounting plate 1 and a second mounting plate 2. A connecting plate 3 is provided on the second mounting plate 2. A fixed pin 4 is provided between the connecting plate 3 and the first mounting plate 1. First baffles 5 and second baffles 6 are respectively provided on the first mounting plate 1 on both sides of the connecting plate 3.

An adjusting assembly is provided between the sliding plates 10 and the fixing frames 7. Damping pads are provided on the sliding plates 10, the first baffles 5 and the second baffles 6.

[0024] During the working process, as the relative rotation between the first mounting plate 1 and the second mounting plate 2 occurs, the connecting plate 3 rotates around the fixed pin 4. The connecting plate 3 drives the fixed frame 7 and the sliding plate 10 to move accordingly. When the sliding plate 10 is blocked by the first baffle 5 or the second baffle 6, it stops. At the same time, the damping pads on the sliding plate 10 come into contact with the corresponding damping pads on the first baffle 5 or the second baffle 6 and buffer, improving the comfort during the use of the device and avoiding impact damage.

[0025] As Figure 3 shown, the adjusting assembly includes a fixed plate 11. The fixed plate 11 is slidably installed inside the fixed frame 7. An adjusting rod 14 is provided on the fixed plate 11. The adjusting rod 14 is rotatably connected to the fixed plate 11. A threaded cylinder 15 is provided at one end of the fixed frame 7. The adjusting rod 14 is threadedly connected to the threaded cylinder 15. The staff drives the adjusting rod 14 to rotate through a screwdriver tool. The adjusting rod 14 rotates on the fixed plate 11. At the same time, the adjusting rod 14 moves on the adjusting rod 14, and at the same time pushes the fixed plate 11 to move accordingly, so as to adjust the position of the fixed plate 11.

[0026] Combined with Figure 3 、 Figure 4 shown, the adjusting assembly further includes a damping rod 12. One end of the damping rod 12 is fixedly connected to the sliding plate 10. The other end of the damping rod 12 passes through the fixed plate 11 and is fixedly connected to the fixed plate 11 through a U-shaped plate. A tension spring 13 is provided on the damping rod 12. One end of the tension spring 13 is fixedly connected to the damping rod 12. The other end of the tension spring 13 is fixedly connected to the sliding plate 10. When the fixed plate 11 moves, it drives the sliding plate 10 to move through the damping rod 12 and the tension spring 13, so as to adjust the position of the sliding plate 10. When the sliding plate 10 is blocked by the first baffle 5 or the second baffle 6, the damping rod 12 and the tension spring 13 cooperate with each other to make further buffering, thereby improving the stability of the device and reducing the impact damage to the device.

[0027] In a preferred embodiment, four damping rods 12 are provided. The four damping rods 12 are arranged at the four corners of the sliding plate 10, so that the sliding plate 10 is evenly stressed when being impacted. A bidirectional threaded rod 8 is provided on one side of the two fixed frames 7. The bidirectional threaded rod 8 is rotatably installed on the connecting plate 3. The two ends of the bidirectional threaded rod 8 are respectively threadedly connected to the corresponding fixed frames 7. The staff adjusts the rotation of the bidirectional threaded rod 8. The bidirectional threaded rod 8 drives the two fixed frames 7 to move relatively, so as to adjust the distance between the two fixed frames 7 and synchronously adjust the sliding plate 10, improving the convenience during use.

[0028] As Figure 2As shown in the figure, on the side of the two fixed frames 7 far away from the bidirectional threaded rod 8, there is a limit rod 9 installed on the connecting plate 3. The limit rod 9 is slidably arranged with the fixed frame 7. When the fixed frame 7 moves, it slides on the limit rod 9, and the position of the fixed frame 7 is restricted by the limit rod 9, so as to maintain the stability of the fixed frame 7 during the working process. The limit rod 9 and the bidirectional threaded rod 8 are horizontally arranged, and both the limit rod 9 and the bidirectional threaded rod 8 are respectively arranged in the middle of both sides of the fixed frame 7.
