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 scope of protection of the present utility model.

[0025] Please see Figures 1-6As shown, an adjustable damping push door hinge includes a first hinge body 1; a second hinge body 2 is provided on the left side of the first hinge body 1, and a damping adjustment mechanism is provided between the first hinge body 1 and the second hinge body 2.

[0026] The damping adjustment mechanism includes a rotating plate 10, which is disposed between the first hinge body 1 and the second hinge body 2. The rotating plate 10 is also provided with resistance blocks 11 at both ends. The outer side of the resistance block 11 is fixedly connected to the first fixed block 12. The first fixed block 12 is fixedly connected to the first fixed seat 13. One end of the push rod 14 is sleeved on the outer side of the first fixed seat 13, and the push rod 14 is rotatably connected to the first fixed seat 13. The other end of the push rod 14 is sleeved on the outer side of the second fixed seat 15, and the push rod 14 is rotatably connected to the second fixed seat 15. The inner wall of the push rod 14 is circular.

[0027] When in operation, the moving disk 16 moves, which will drive the second fixed seat 15 to move synchronously. The second fixed seat 15 applies a pushing force to the push rod 14, causing the push rod 14 to rotate along the inside of the second fixed seat 15. At the same time, when the push rod 14 rotates, it also rotates along the inside of the first fixed seat 13, and pushes the first fixed seat 13 and the first fixed block 12 to move outward.

[0028] Furthermore, the top of the second fixed seat 15 is fixedly connected to the bottom of the movable disk 16. The movable disk 16 is sleeved on the outside of the threaded rod 17, and the movable disk 16 is slidably connected to the threaded rod 17. The bottom of the threaded rod 17 is fixedly connected to the top of the rotating plate 10, and the top of the threaded rod 17 is fixedly connected to the bottom of the limiting block 18. The limiting block 18 is a circular design.

[0029] During operation, the movable disk 16 moves along the outside of the threaded rod 17, and the limiting block 18 is used to limit the position of the rotating disk 21.

[0030] Furthermore, the top of the movable disk 16 is fixedly connected to the bottom of the sleeve block 19, the bottom of the rotating block 20 is sleeved inside the sleeve block 19, and the rotating block 20 is rotatably connected to the sleeve block 19. The inner wall of the sleeve block 19 is circular.

[0031] When the rotating disk 21 rotates, it drives the rotating block 20 to rotate along the inside of the sleeve block 19.

[0032] Furthermore, the top end of the rotating block 20 is fixedly connected to the bottom end of the rotating disk 21, the rotating disk 21 is sleeved on the outside of the threaded rod 17, and the rotating disk 21 is threadedly connected to the threaded rod 17.

[0033] During operation, the rotating block 20 rotates and moves along the outside of the threaded rod 17 towards the position of the rotating plate 10.

[0034] Furthermore, one end of the resistance block 11 is fixedly connected to one end of the moving guide rod 22, the rotating plate 10 is provided with a guide groove 23, the other end of the moving guide rod 22 is inserted into the guide groove 23, and the moving guide rod 22 is slidably connected to the guide groove 23. The moving guide rod 22 is a circular rod design, and the front and rear ends of the top of the hinge second body 2 are also fixedly connected with resistance plates 24.

[0035] During operation, the first fixed block 12 moves outward, which in turn moves the resistance block 11 toward the resistance plate 24 and abuts against it. When the resistance block 11 and the resistance plate 24 are in close contact, the resistance is greater. At the same time, when the resistance block 11 moves, it drives the moving guide rod 22 to move along the inside of the guide groove 23.

[0036] Furthermore, the right side of the second hinge body 2 is fixedly connected to the fixed rod 25, the left side of the rotating plate 10 is sleeved on the outside of the fixed rod 25, and the rotating plate 10 is rotatably connected to the fixed rod 25. The right side of the rotating plate 10 is sleeved on the left side of the first hinge body 1, and the rotating plate 10 is rotatably connected to the first hinge body 1.

[0037] During operation, the second hinge body 2 rotates, causing the rotating plate 10 to rotate along the fixed rod 25 and the outer side of the first hinge body 1.

[0038] Working principle: When damping needs to be increased, the rotating disk 21 is rotated first. When the rotating disk 21 rotates, it drives the rotating block 20 to rotate along the inside of the sleeve block 19. When the rotating block 20 rotates, it will move along the outside of the threaded rod 17 towards the position of the rotating plate 10, and at the same time drive the moving disk 16 to move along the outside of the threaded rod 17. The limiting block 18 is used to limit the position of the rotating disk 21. At the same time, when the moving disk 16 moves, it will drive the second fixed seat 15 to move synchronously. The second fixed seat 15 applies a pushing force to the push rod 14, causing the push rod 14 to move along the inside of the second fixed seat 15. As the push rod 14 rotates, it also rotates along the inside of the first fixed seat 13, pushing the first fixed seat 13 and the first fixed block 12 to move outward. When the first fixed block 12 moves outward, it simultaneously drives the resistance block 11 to move towards the position of the resistance plate 24 and abut against it. When the resistance block 11 and the resistance plate 24 are in close contact, the resistance is greater. At the same time, when the resistance block 11 moves, it drives the moving guide rod 22 to move along the inside of the guide groove 23. And when the second body 2 of the hinge rotates, it drives the rotating plate 10 to rotate along the outside of the fixed rod 25 and the first body 1 of the hinge.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
