Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and specifically relates to a concealed connecting hinge. Background Art

[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. A hinge can be composed of movable components or foldable materials. Hinges are more commonly installed on cabinets. Classified by material, they are mainly divided into stainless steel hinges and iron hinges. To provide people with a better experience, hydraulic hinges (also known as damping hinges) have emerged. Their characteristic is to provide a buffering function when the cabinet door is closed, minimizing the noise generated by the collision between the cabinet door and the cabinet body when the door is closed. They are mainly used for cabinet doors and wardrobe doors, and generally require a board thickness of 18 - 20 mm. Classified by material, they can be divided into galvanized iron and zinc alloy. Classified by performance, they can be divided into two types: those that require drilling holes and those that do not. The ones that do not require drilling holes are what we call bridge hinges. A bridge hinge looks like a bridge, so it is commonly called a bridge hinge. Its characteristic is that it does not require drilling holes in the door panel and is not restricted by the style. The specifications are: small size, medium size, and large size. Those that require drilling holes are the spring hinges commonly used on cabinet doors, etc. Their characteristics are: the door panel must be drilled, the style of the door is restricted by the hinge, the door will not be blown open after being closed, and there is no need to install various catches. The specifications are: 26, 35. Among them, there are detachable directional hinges and non-detachable non-directional hinges.

[0003] The application number is CN201520700922.3, which discloses a super-load bearing concealed hinge and a window frame structure with this hinge. One end of a thick load-bearing support rod is rotatably connected to a window frame fixing seat, and the other end is rotatably connected to one end of a window sash fixing seat. The other end of the window sash fixing seat is rotatably connected to one end of a diagonal load-bearing support rod. The middle part of the diagonal load-bearing support rod is rotatably connected to one end of a thin load-bearing support rod. The other end of the thin load-bearing support rod is rotatably connected to the window frame fixing seat. A limit sliding column is arranged at the other end of the diagonal load-bearing support rod, and a limit sliding track matching with the limit sliding column is arranged on the window frame fixing seat. The limit sliding column at the other end of the diagonal load-bearing support rod can be slidably limited in the limit sliding track. In the super-load bearing concealed hinge of the utility model, the thick load-bearing support rod, the window frame fixing seat, the window sash fixing seat, the diagonal load-bearing support rod, and the thin load-bearing support rod are connected to each other in a staggered manner, realizing that the thickness of the thick load-bearing support rod is 5 mm - 20 mm, the thickness of the thin load-bearing support rod is 2 mm - 15 mm, and the load-bearing capacity reaches 120 kg; the structure is simple and very practical.

[0004] Although the above utility model is connected to each other in a staggered manner through thick support rods, window frame fixing seats, window sash fixing seats, load-bearing inclined pull rods and thin load-bearing support rods, the thickness of the thick load-bearing support rod is 5 mm - 20 mm, the thickness of the thin load-bearing support rod is 2 mm - 15 mm, and the load-bearing capacity reaches 120 kg; the structure is simple and very practical, but the disadvantage is that when the device is used, after a long period of use, it is very easy to generate noises caused by rusting and other conditions, and the situation of unsmooth opening occurs.

[0005] Therefore, it is necessary to add a four-component fixing plate to the device, which can not only reinforce and fix at multiple angles when using the device, but also provide a certain lubricating effect during fixation, so as to avoid a series of influences such as noises caused by rusting during multiple uses and unsmooth use.
