[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-5 As shown, a non-damped inward push door hinge includes a first hinge body 1; a second hinge body 2 is provided at the left end of the first hinge body 1; a door frame body 3 and a door body 4 are respectively provided at the front ends of the first hinge body 1 and the second hinge body 2; and a non-damped assembly mechanism is provided between the first hinge body 1 and the second hinge body 2.

[0025] The undamped assembly mechanism includes a first fixed rod 10, which is located inside the left side of the first hinge body 1 and is fixedly connected to the first hinge body 1. A rotating plate 11 is provided on the left side of the first hinge body 1. The upper and lower ends of one end of the rotating plate 11 are also fixedly connected to a first self-lubricating bushing 12. The first self-lubricating bushing 12 is sleeved on the outside of the first fixed rod 10 and is rotatably connected to the first fixed rod 10. The first fixed rod 10 is a circular rod design. The upper and lower ends of the other end of the rotating plate 11 are also fixedly connected to a second self-lubricating bushing 13. The second self-lubricating bushing 13 is sleeved on the outside of the second fixed rod 14 and is rotatably connected to the second fixed rod 14. The second fixed rod 14 is fixedly connected to the inner wall of the second hinge body 2 and is a circular rod design.

[0026] When in operation, the door body 4 opens, causing the second hinge body 2 to rotate. When the second hinge body 2 rotates, it causes the rotating plate 11 to rotate simultaneously, causing the first self-lubricating bushing 12 and the second self-lubricating bushing 13 to rotate along the outer side of the first fixed rod 10 and the outer side of the second fixed rod 14, respectively. During the friction process, the first self-lubricating bushing 12 and the second self-lubricating bushing 13 can actively release lubricating substances to form a friction-reducing layer, thereby replacing traditional grease lubrication to reduce damping.

[0027] Furthermore, the upper and lower ends of the rear ends of the first hinge body 1 and the second hinge body 2 are also fixedly connected to the fixing plates 15. The fixing plates 15 are inserted with fixing rods 16, and the fixing plates 15 are slidably connected to the fixing rods 16. One end of the fixing rods 16 is fixedly connected to the pull plate 17. The fixing rods 16 are designed as round rods.

[0028] During operation, the pull plates 17 at the rear ends of the first hinge body 1 and the second hinge body 2 are pressed towards the center simultaneously. When the pull plates 17 are pressed inward, they drive the fixed rod 16 to move along the inside of the fixed plate 15.

[0029] Furthermore, two sets of fixing blocks 18 are also fixedly connected to the upper and lower ends of the rear end of the door frame body 3 and the door body 4. The other end of the fixing rod 16 is inserted into the fixing block 18, and the fixing rod 16 is slidably connected to the fixing block 18. The inner wall of the fixing block 18 is circular.

[0030] During operation, the fixed insertion rod 16 will move outward along the inside of the fixed block 18 until it is completely disengaged.

[0031] Furthermore, the outer side of the fixed insertion rod 16 is fixedly connected to the stop block 19, and a return spring 20 is sleeved on the outer side of the fixed insertion rod 16. One end of the return spring 20 is fixedly connected to the fixed plate 15, and the other end of the return spring 20 is fixedly connected to the stop block 19.

[0032] During operation, the fixed insertion rod 16 moves, causing the stop block 19 to move synchronously. During the movement of the stop block 19, the return spring 20 will be compressed and contracted.

[0033] Furthermore, the upper and lower ends of the door frame body 3 and the door body 4 are also provided with positioning rods 21, and the door frame body 3 and the door body 4 are fixedly connected to the positioning rods 21 respectively. The first hinge body 1 and the second hinge body 2 are also sleeved on the outside of the positioning rods 21, and the first hinge body 1 and the second hinge body 2 are slidably connected to the positioning rods 21. The positioning rods 21 are designed as round rods.

[0034] During operation, the first hinge body 1 and the second hinge body 2 are pulled outward, causing them to move outward along the outside of the positioning rod 21 until they disengage from the internal positioning rod 21.

[0035] Furthermore, the rear end of the door frame body 3 is fixedly connected to the front end of the positioning block 22, the first hinge body 1 is inserted into the positioning block 22, and the first hinge body 1 is slidably connected to the positioning block 22. The rear end of the door body 4 is provided with a slot 23, the front end of the second hinge body 2 is inserted into the slot 23, and the second hinge body 2 is slidably connected to the slot 23.

[0036] During operation, as the first hinge body 1 and the second hinge body 2 are pulled outward, the right end of the first hinge body 1 will move outward along the inside of the positioning block 22, and the second hinge body 2 will move outward along the inside of the slot 23 until they are completely disengaged.

[0037] Working principle: When the door body 4 is opened during use, it drives the second hinge body 2 to rotate. When the second hinge body 2 rotates, it drives the rotating plate 11 to rotate the first self-lubricating bushing 12 and the second self-lubricating bushing 13 along the outer side of the first fixed rod 10 and the outer side of the second fixed rod 14, respectively. During the friction process, the first self-lubricating bushing 12 and the second self-lubricating bushing 13 can actively release lubricating substances to form a friction-reducing layer, thereby replacing the traditional grease lubrication to reduce damping.

[0038] When disassembly is required for later replacement, first press the pull plates 17 at the rear ends of the first hinge body 1 and the second hinge body 2 towards the center simultaneously. When the pull plates 17 are pressed inward, they drive the fixing rod 16 to move along the inside of the fixing plate 15. At the same time, the fixing rod 16 will move outward along the inside of the fixing block 18 until it is completely disengaged. Simultaneously, the movement of the fixing rod 16 drives the stop block 19 to move synchronously. During the movement of the stop block 19, it will compress the return spring 20 and retract it. Finally, when the fixing rod 16 is completely disengaged from the fixing plate 15... After the first hinge body 1 and the second hinge body 2 are placed inside the positioning block 18, the first hinge body 1 and the second hinge body 2 are pulled outwards, causing the first hinge body 1 and the second hinge body 2 to move outwards along the outside of the positioning rod 21 simultaneously, until the first hinge body 1 and the second hinge body 2 are respectively disengaged from the internal positioning rod 21. During the outward pulling of the first hinge body 1 and the second hinge body 2, the right end of the first hinge body 1 will move outwards along the inside of the positioning block 22, and the second hinge body 2 will move outwards along the inside of the slot 23, until they are completely disengaged.
