[0001] This utility model relates to the field of hinge equipment technology, specifically a hardware buffer hinge for furniture. Background Technology

[0002] In the field of furniture hardware, hinges, as the core component connecting door panels and cabinets, play a crucial role in the user experience. Early traditional hinges only met basic opening and closing functions and lacked cushioning design. When the door panel closed, it was prone to violent collisions with the cabinet, which not only generated noise but also accelerated wear and tear on the door panel and cabinet, shortening the lifespan of the furniture. As users' requirements for furniture comfort and quality have increased, cushioning hinges have gradually become more popular. However, existing cushioning hinges still have many shortcomings: the damping structure of some products lacks precise limiting, resulting in excessive displacement of the damping components during the cushioning process and a decrease in cushioning performance. To address these issues, the inventor has proposed a furniture hardware cushioning hinge to solve these problems. Utility Model Content

[0019] 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 protection scope of the present utility model.

[0020] Example: Figure 1-4As shown, this utility model provides a technical solution: a hardware buffer hinge for furniture, including a fixed base 1, a connector 11 at one end of the fixed base 1, a shell 12 movably sleeved on the top of the connector 11, a base plate 13 movably snapped onto the bottom of the connector 11, symmetrically distributed insertion holes 14 at one end of the fixed base 1, a pin 15 movably inserted into the inner side of the insertion hole 14, a movable outer arm 16 rotatably connected to the bottom of the pin 15, a first inner arm 17 rotatably connected to the top of the pin 15, a first connecting groove 18 at one end of the first inner arm 17, a first connecting shaft 19 movably inserted into the inner side of the first connecting groove 18, one end of the movable outer arm 16 movably sleeved on the outer side of the first connecting shaft 19, a second connecting groove 20 at one end of the first inner arm 17, and a first connecting shaft 19 movably inserted into the inner side of the second connecting groove 20. The second shaft 21 has a second inner arm 22 movably sleeved on its outer side. A third shaft 23 is movably inserted into one end of the second inner arm 22. A third inner arm 24 is movably sleeved on the outer side of the third shaft 23. A fourth shaft 25 is movably inserted into the middle of the third inner arm 24. One end of the connecting piece 11 is connected to the fourth shaft 25. A third groove 26 is provided at one end of the third inner arm 24. A rotating connecting piece 27 is movably inserted into the inner side of the third groove 26. A piston rod 28 is movably connected to the outer side of the rotating connecting piece 27. A damping cylinder 29 is movably installed on the inner side of the connecting piece 11. One end of the piston rod 28 is movably connected to the damping cylinder 29. A fourth groove 30 is provided at one end of the connecting piece 11. A fifth shaft 31 is movably inserted into the inner side of the fourth groove 30. A rear connecting piece 32 is connected to the outer side of the fifth shaft 31.

[0021] By adopting the above technical solution, the movement range of the damping cylinder 29 is precisely limited by the movement of the limiting post 33 within the limiting groove 34, preventing damage to the damping structure due to excessive displacement during the buffering process, and ensuring that the buffering and shock absorption effect is stable and reliable each time it is closed. If the buffering effect needs to be adjusted, the damping effect can be adjusted.

[0022] A limit post 33 is movably installed at one end of the damping cylinder 29, and a limit groove 34 is opened at one end of the connector 11. The two ends of the limit post 33 are movably locked inside the limit groove 34.

[0023] By adopting the above technical solution, the movement range of the auxiliary damping cylinder 29 is controlled by setting the limit post 33 to move in the limit groove 34.

[0024] The top of the connector 11 is provided with a groove 35, and an adjusting screw 36 is movably installed on the inner side of the groove 35.

[0025] By adopting the above technical solution, the adjusting screw 36 can be finely adjusted by sliding in the slide groove 35, which effectively improves the alignment and gap uniformity and ensures the effect of use.

[0026] The top of the outer casing 12 is movably abutted against a positioning screw 37, one end of which is threaded onto the top of the connector 11.

[0027] By adopting the above technical solution, the housing 12 and the connector 11 are reinforced by setting the positioning screw 37.

[0028] A rear spring 38 is installed on the outer side of the fifth connecting shaft 31, and a front spring 39 is installed on the inner side of the movable outer arm 16.

[0029] By adopting the above technical solution, energy is stored or released during the opening and closing of the door panel through the action of the rear spring 38 and the front spring 39, which not only assists the movement of the door panel, but also avoids the movement jamming caused by simple damping, making the closing process smoother and more stable.

[0030] A hook block 40 is fixedly installed at one end of the connector 11, and a hook groove 41 is opened at one end of the base plate 13. One end of the hook block 40 is movably engaged with the inside of the hook groove 41.

[0031] By adopting the above technical solution, the base plate 13 is assembled and fixed by hooking the hook block 40 into the hook groove 41.

[0032] The top of the outer casing 12 is provided with a protective cover 42, and the bottom of the protective cover 42 is fixedly installed with symmetrically distributed elastic pieces 43. The top of the outer casing 12 is provided with a notch 44, and one end of the elastic piece 43 is movably engaged with the inside of the notch 44.

[0033] By adopting the above technical solution, the protective cover 42 helps to prevent rust on the positioning screw 37, and the elastic piece 43 is inserted into the groove 44 to help fix the protective cover 42.

[0034] Working principle: The mounting base 1 is fixed to the cabinet via the insertion hole 14 and the pin 15. The base plate 13 is engaged with the hook block 40 and the hook groove 41 to form a stable foundation. The outer shell 12 is reinforced by the positioning screw 37. The protective cover 42, together with the elastic sheet 43, protects the components and prevents rust from affecting the buffering performance. When the door is closed, the external force drives the rear connecting piece 32, which drives the third inner arm 24 via the fifth connecting shaft 31. Through the rotating connecting piece 27, the piston rod 28 moves towards the damping cylinder 29. At this time, the damping medium (such as hydraulic oil) in the damping cylinder 29 is squeezed by the piston rod 28 and forced to pass through the throttling channel, generating strong damping resistance, which significantly slows down the movement speed of the piston rod 28, directly reducing the closing rate of the door and realizing the core buffering and shock absorption.

[0035] Subsequently, the front spring 39 and rear spring 38 release elastic potential energy when the door panel is closed, which works in conjunction with the damping force of the damping cylinder 29: the spring force assists the door panel to move smoothly, avoiding movement jamming caused by a single damping force, making the door panel closing process both slow and smooth, further enhancing the buffering and shock absorption performance. The limiting post 33 moves within the limiting groove 34, precisely limiting the movement range of the damping cylinder 29, preventing damage to the damping structure due to excessive displacement during the buffering process, and ensuring that the buffering and shock absorption effect is stable and reliable each time it is closed. If the buffering effect needs to be adjusted, the hinge structure can be finely adjusted by sliding the adjusting screw 36 within the slide groove 35, so that the damping components and springs and other buffering components match the door panel more precisely, optimizing the adaptability of buffering and shock absorption, and ensuring the user experience.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
