Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a buffer hinge. Background Technology

[0002] Hinges, also known as hinges, are mechanical devices used to connect two solid objects and allow relative rotation between them. Currently, most cabinets use two-stage damping hinges, which employ a damper and spring to form a damping structure. This damping structure provides a soft closing effect when the door is closed, preventing damage to the door. However, because the door panel is relatively unresponsive when the door is opened more than 45°, it can hover at any position. Therefore, when the door is opened with greater force, the door panel will impact the cabinet, causing damage to the door panel, cabinet, or hinge. Furthermore, the door panel should be installed at its maximum opening angle, so any wobbling at this angle can easily lead to installation errors.

[0003] The technical problem to be solved by this application is: to design a buffer hinge that can buffer and position the cabinet door when it is opened to its maximum extent, thereby preventing the cabinet door from impacting the cabinet body with great force when it is opened to its maximum angle. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a buffer hinge that can buffer and position the cabinet door when it is opened to its maximum extent, thereby preventing the cabinet door from impacting the cabinet body with great force when it is opened to its maximum angle.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a buffer hinge, including a hinge cup 1 and a hinge arm 2 that is pulsatorically connected to the hinge cup 1. A stacked plate assembly 3 is provided between the hinge cup 1 and the hinge arm 2 for mutual connection. A U-shaped nail 10 is provided on the hinge cup 1 and mounted thereon. The stacked plate assembly 3 and the U-shaped nail 10 are rotatably connected. The hinge cup 1 also has a cover plate 11 that rotatably engages with it. First limiting holes 12 and second limiting holes 13 are provided on both sides of the hinge cup 1. The U-shaped nail 10 has a first connecting part 101 and a second connecting part 101. The first connecting part 101 of the U-shaped nail 10 is limited and engaged with the first limiting holes 12 on both sides of the hinge cup 1, and the second connecting part 102 of the U-shaped nail 10 is limited and engaged with the second limiting holes 13 on both sides of the hinge cup 1. A first connecting hole 111 and a second connecting hole 112 are correspondingly provided on both sides of the cover plate 11. The first connecting hole 111 of the cover plate 11 is rotatably connected to the first connecting part 101 of the U-shaped nail 10. Hinge holes 20 are correspondingly provided on both sides of the hinge arm 2. A limiting pin 21 is provided between the two sides of the cover plate 11. The second connecting hole 112 of the cover plate 11 is rotatably connected to the limiting pin 21. The cover plate 11 has a first side wing 113 and a second side wing 114 on both sides. The first connecting hole 111 is provided on the first side wing 113 and the second connecting hole 112 is provided on the second side wing 114. A protrusion 110 is also provided on the first side wing 113 of the cover plate 11. The protrusion 110 is located at one end of the first side wing 113 near the second connecting part 102 of the U-shaped pin 10. When the hinge cup 1 and the hinge arm 2 are opened to the maximum angle, which is equivalent to the cabinet door and the cabinet body being opened to the maximum angle, the protrusion 110 on the first side wing 113 of the cover plate 11 and the second connecting part 102 of the U-shaped nail 10 make a limiting contact, thereby generating a buffering friction force to buffer and position the cabinet door, thereby buffering the cabinet door and slowing down the opening speed of the cabinet door, avoiding the noise caused by a strong impact, and also preventing the door panel from being damaged by a strong impact between the cabinet door and the cabinet body.

[0020] One end of the stacked plate assembly 3 is rotatably connected to the second connecting part 102 of the U-shaped nail 10, and the other end of the stacked plate assembly 3 is connected to the hinge arm 2. A mounting base 22 is also provided below the hinge arm 2 and connected thereto. The mounting base 22 is equipped with a hydraulic assembly, which includes a hydraulic cylinder 23 connected to the mounting base 22. The driving end of the hydraulic cylinder 23 is provided with a triangular connector 4 that is connected to it for transmission. One end of the triangular connector 4 is rotatably connected to one end of the stacked plate assembly 3. When the cabinet door is opened, as the angle between the hinge cup 1 and the hinge arm 2 increases, the stacked plate assembly 3 will drive the triangular connector 4 to move, thereby causing the triangular connector 4 to pull the driving end of the hydraulic cylinder 23, thereby generating a buffering force to buffer the cabinet door, thus preventing the cabinet door from hitting the cabinet body due to excessive speed when it is opened.

[0021] The working principle of this utility model is as follows: The hinge cup 1 is provided with a cover plate 11 that rotates with it. The cover plate 11 is provided with a protrusion 110. When the hinge cup 1 and the hinge arm 2 are opened to the maximum angle, the protrusion 110 and the U-shaped nail 10 make a limiting contact. By providing protrusions 110 on both sides of the cover plate 11, when the hinge cup 1 and the hinge arm 2 are opened to the maximum angle, which is equivalent to the cabinet door and the cabinet body being opened to the maximum angle, the protrusion 110 on the cover plate 11 can make a limiting contact with the U-shaped nail 10, thereby generating a buffer friction force, which can buffer the cabinet door and slow down the opening speed of the cabinet door, thereby preventing the cabinet door and the cabinet body from having a strong impact and damaging the door panel.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
