Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and more particularly to a switchable buffer hinge structure. Background Technology

[0002] Hinges, as the core hardware accessories connecting furniture doors and cabinets, are widely used in various scenarios such as wardrobes, cabinets, and bookcases.

[0003] Traditional hinges are divided into two types: hinges without cushioning and hinges with cushioning. Furniture door hinges without cushioning produce a loud slamming sound when the door closes. Although hinges with cushioning can avoid the noise of the door hitting the cabinet when it closes quickly, in actual use, users usually only choose one type of hinge: either a hinge with cushioning or one without. This fails to meet the different needs of different scenarios and is difficult to adapt to diverse user preferences. Therefore, existing hinges need further improvement. Utility Model Content

[0023] Example: Figure 1-12 As shown, the switchable buffer hinge structure includes a hinge cup 1, a hinge arm 2, a pin 3, and a damper 4. The hinge cup 1 and the hinge arm 2 are rotatably connected via the pin 3. The damper 4 is mounted on the side wall of the hinge cup 1. It also includes a slider 5 and a switching element 6 with a protrusion 61. The slider 5 is slidably mounted within the cavity 10 of the hinge cup 1. The outer rocker arm 21 of the hinge arm 2 is provided with a groove 22. The switching element 6 is slidably connected to the outer rocker arm 21 through the engagement of the protrusion 61 and the groove 22. When the switching element is in the first position of the groove, the hinge rotates in the closing direction, and the switching element causes the slider to slide downwards, generating a buffer. Impact force; when the switching element is in the second position of the slide, the hinge rotates in the closing direction, and the switching element does not drive the slide plate to slide, thus generating no cushioning force; by setting the switching element, the hinge can switch between cushioned and uncushioned modes. The switching method of the cushioning mode is simple and easy to operate. Users can switch the cushioning mode to adapt to different usage scenarios and meet the needs of different users. For furniture manufacturers, there is no need to stock two types of hinges separately, which simplifies the supply chain management and production inventory process. For users, there is no need to predict long-term needs in advance when purchasing, and the trouble of replacing hinges due to changes in needs later is avoided, which is conducive to improving the user experience.

[0024] The bump is slightly higher than the top surface of the slide, making it easier for the user to push the bump to switch the buffer mode.

[0025] The slide plate 5 has a first protrusion 51 on one side, which corresponds to the first position of the slide groove. The switching member 6 has a hook 62 corresponding to the first protrusion 51. When the hinge rotates in the closing direction, the outer rocker arm of the hinge arm drives the switching member to rotate, so that the hook of the switching member pushes the first protrusion, thereby causing the slide plate to slide downward.

[0026] The outer rocker arm 21 has a protrusion 23 at one end facing the slide plate 5. When the hinge rotates in the opening direction, the protrusion on the outer rocker arm pushes the slide plate up to the initial position, preparing for the next closing.

[0027] The slider 5 is provided with a second protrusion 52 corresponding to the protrusion 23. The provision of the second protrusion increases the contact area between the protrusion of the outer rocker arm and the slider, which is beneficial to improving the stability of the slider being reset by the protrusion pushing the second protrusion.

[0028] The system also includes a spring 7. A first connecting post 53 is provided on one side of the slider 5, and a second connecting post 11 is provided on the wall of the cavity 10 of the hinge cup 1. One end of the spring 7 is sleeved on the first connecting post 53, and the other end of the spring 7 is sleeved on the second connecting post 11. The spring pushes the slider to move away from the outer rocker arm. The spring is provided to assist the slider in resetting.

[0029] The slider 5 is provided with a guide groove 54, and the hinge cup 1 is provided with a positioning post 12 corresponding to the guide groove 54. The positioning post 12 is located in the guide groove 54. The cooperation between the guide groove and the positioning post can limit the sliding path of the slider in the hinge cup cavity, which is beneficial to improving the stability of the slider when sliding in the hinge cup cavity.

[0030] The device also includes a limiting piece 8, which has a limiting point 81. The hinge cup 1 has a positioning hole 13 corresponding to the guide groove 54. The limiting point 81 is assembled in the positioning hole 13. The setting of the limiting piece further improves the stability of the connection between the slide and the hinge cup and can improve the smoothness of the slide when it slides in the hinge cup cavity.

[0031] The limiting piece 8 has a downward-facing side with a block 82 that matches the guide groove 54. The block 82 is assembled in the guide groove 54, and the limiting point 81 is located on the block 82. The block makes the limiting piece more securely assembled in the guide groove, which can improve the stability of the limiting piece in the hinge cup cavity.

[0032] The downward-facing side of the limiting piece 8 is attached to or nearly attached to the sliding piece 5.

[0033] Among them, a protrusion 55 is provided on one or both sides of the slider 5. The side of the protrusion 55 near the guide groove 54 is attached to or nearly attached to the side of the limiting piece 8, which helps to improve the stability of the slider when sliding in the hinge cup cavity.

[0034] The slider 5 is provided with a clearance part 56 to make way for the protrusion 61. The clearance part makes way for the protrusion to prevent the protrusion and slider from interfering with each other when the hinge is closed, thus preventing it from closing completely.

[0035] The device also includes a fixing frame 9. The side wall of the hinge cup 1 is provided with a through hole 14. The spindle 41 of the damper 4 is inserted into the through hole 14. The other end of the damper 4 is connected to the side wall of the hinge cup 1 through the fixing frame 9. The damper is fixed in a simple way, which is convenient for assembly during production and can reduce the production cost of the hinge.

[0036] The fixed frame 9 has mounting holes 91 on both sides. The side wall of the hinge cup 1 is provided with a connecting post 15 corresponding to one side of the fixed frame 9. The connecting post 15 is inserted into the mounting hole 91 on one side of the fixed frame 9. The damper 4 is provided with a connecting part at one end away from the spindle. The connecting part is inserted into the mounting hole 91 on the other side of the fixed frame 9. The fixed frame is approximately L-shaped. The damper is fixed in a simple way, which is convenient for assembly during production and can reduce the production cost of the hinge.

[0037] The slide plate 5 is provided with a first protrusion 57, and the first connecting post 53 is located on the protrusion 57. The provision of the first protrusion can improve the stability of the first connecting post connected to the slide plate.

[0038] The slide 5 is provided with a second protrusion 58, which is corresponding to the spindle of the damper. When the hinge rotates in the closing direction, the slide is pushed downward, and the second protrusion on the slide pushes the spindle of the damper into the damper. The damper generates a damping force, which reacts on the slide and is transmitted to the hinge through the linkage mechanism, thereby slowing down the closing speed of the door and achieving a buffering effect.

[0039] The first connecting column is formed by stamping from one side of the first protrusion to the other side, which facilitates production.

[0040] The second connecting post and / or positioning post and / or connecting post are formed by stamping from one side of the hinge cup to the other side, which facilitates production.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
