Description

Technical Field

[0001] The utility model belongs to the technical field of hinges, and particularly relates to a hydraulic hinge. Background Art

[0002] In modern architecture and mechanical equipment, hinges, as key components for connecting two objects (such as doors and door frames), their stability and durability are crucial for the normal operation of the equipment. Traditional hinges mainly achieve the opening and closing functions of objects through mechanical structures. However, in occasions of high-frequency use, these traditional hinges often encounter some technical problems during the opening and closing process.

[0003] First of all, many traditional hinges are prone to the problem of unsmooth opening and closing during long-term use. This is mainly caused by the friction of the hinge and the wear of the fittings, resulting in uneven forces when the door or other components are opened and closed, thereby causing impacts and noises. This unsmooth opening and closing not only affects the user experience but also may accelerate the damage of the equipment and shorten the service life of the equipment.

[0004] Secondly, traditional hinges have deficiencies in the stability of the hydraulic system. Hydraulic hinges are widely used in scenarios where the opening and closing speed and force need to be adjusted, such as car doors, high-end furniture, etc. However, traditional hydraulic hinges often have leakage and mixing problems in the design of the hydraulic system. These problems not only affect the stability of the hydraulic system but also lead to a decrease in the efficiency of the hydraulic oil, thereby affecting the use effect of the hinge.

[0005] In addition, in the design of hydraulic hinges, the mechanisms for adjusting the flow rate of hydraulic oil and the return function are often not delicate enough. This means that users cannot accurately control the opening and closing speed, or the hinge cannot effectively return after opening and closing, thus affecting the normal operation and use comfort of the equipment.

[0006] In view of this, overcoming the above-mentioned defects of the existing technology is an urgent problem to be solved in this technical field. Content of the Utility Model

Detailed implementation manner

[0022] As Figures 1 to 5 shown, a hinge includes a first hinge plate 10 and a second hinge plate 20. Among them, the first hinge plate 10 and the second hinge plate 20 are hinged to each other, and a hydraulic assembly 30 is provided between the first hinge plate 10 and the second hinge plate 20, thus forming the present hinge.

[0023] In specific implementation, the hydraulic assembly 30 includes a guiding bushing 31. An inner part of the guiding bushing 31 is provided with a wick member 32. One end of the wick member 32 is provided with a wick mounting portion 321. An inner part of the wick mounting portion 321 is provided with a gear oil ring 322. A front part of the gear oil ring 322 is provided with an oil ring rubber seal 323. A rear part of the gear oil ring 322 is provided with a retaining ring 324. An outer side of the wick mounting portion 321 is provided with a wick rubber seal 325. When in use, the wick rubber seal 325 and the oil ring rubber seal 323 respectively seal the internal and external oil fluids of the hydraulic system, preventing leakage and mixing. The gear oil ring 322 controls the flow of the oil fluid through its structure, adjusting the moving speed and force of the hydraulic cylinder. The retaining ring 324 limits the movement range of the gear oil ring 322, ensuring the stability and reliability of the hydraulic system. The hydraulic assembly 30 can effectively control the opening and closing speed of the hinge, making the door or other components more stable when opening and closing, reducing the impact caused by unstable opening and closing, and prolonging the service life of the equipment and the door.

[0024] The front edge of the guiding bushing 31 is provided with a pin moving groove 311. A positioning pin 326 is inserted through the front part of the wick member 32, and the positioning pin 326 is connected in the pin moving groove 311. The front part of the guiding bushing 31 is provided with a shaft core sleeve 33, and the shaft core sleeve 33 is threadedly connected to the guiding bushing 31. The front part of the wick member 32 is connected with a top pin member 327, and a thrust block 328 is arranged at the front part of the top pin member 327. A thrust spring 331 is arranged inside the shaft core sleeve 33, and the thrust block 328 abuts against the thrust spring 331. During use, the wick member 32 can move in the guiding bushing 31. At the same time, the positioning pin 326 can move along the pin moving groove 311, so that the wick member 32 sequentially pushes the top pin member 327 and the thrust block 328 to push the thrust spring 331, ensuring the smooth closing of the hinge.

[0025] A return member 329 is sleeved outside the wick member 32, and a return spring 34 is arranged between the return member 329 and the guiding bushing 31. Through the return spring 34, the wick member 32 can be pushed to return, improving the operation comfort of the user.

[0026] A guiding cap 35 is arranged at one end of the guiding bushing 31. A speed control rod connecting member 351 is connected to the middle of the guiding cap 35. An oil wick speed control rod 36 is connected to the middle of the wick member 32, and the rear end of the oil wick speed control rod 36 is connected in the speed control rod connecting member 351. During use, through the connection between the oil wick speed control rod 36 and the speed control rod connecting member 351, the user is allowed to adjust the movement speed of the wick member 32. Changing the setting of the speed control rod can adjust the flow rate of the hydraulic oil, thereby controlling the opening and closing speed of the hinge.

[0027] The end of the shaft core sleeve 33 is connected with a decorative connecting member 37, and a decorative cover 371 is connected to the decorative connecting member 37, thereby preventing the components inside the shaft core sleeve 33 from leaking out and making the whole more beautiful.

[0028] A connecting kit 38 is sleeved outside the connection part of the guiding bushing 31 and the shaft core sleeve 33, and pressure bearings 381 are respectively arranged at both ends of the connecting kit 38. During use, the design of the connecting kit 38 and the pressure bearings 381 enhances the connection stability between the guiding bushing 31 and the shaft core sleeve 33, preventing unstable operation caused by connection looseness, and effectively reducing the wear caused by friction through the pressure bearings 381, thereby prolonging the service life of the components and reducing the maintenance requirements.

[0029] An adjusting screw member 372 is connected inside the decorative connecting member 37. During use, the adjusting screw member 372 is used to adjust the force of opening and closing the door, which is convenient to use.

[0030] In summary, an oil core component 32 is installed inside the guiding bushing 31. One end of the oil core component 32 is provided with an oil core installation part 321. Inside the oil core installation part 321, there is a gear oil passing ring 322. In front of the gear oil passing ring 322, there is an oil passing ring rubber seal 323. Behind the gear oil passing ring 322, there is a stop ring 324. Outside the oil core installation part 321, there is an oil core rubber seal 325. The hinge of the present utility model prevents leakage and mixing, ensures the stability and reliability of the hydraulic system, makes the door or other components more stable when opening and closing, reduces the impact caused by unstable opening and closing, and extends the service life of the equipment and the door.
