Abstract
Description
Technical Field
[0001] The utility model relates to a three-dimensional adjustable rotating arm hinge, which belongs to hardware products. Background Art
[0002] Hinges are a crucial component of door systems. Existing swing-arm hinges for security doors typically feature axially fixed gaskets and lack radial sleeves. When the hinge is under load, significant friction occurs between the swing arm and the gasket surface, and between the core shaft and the swing arm's axis hole. This can cause a squeaking noise over time. Furthermore, the recent market demand for high-end security doors has led to an increasing adoption of concealed hinges. Concealed hinges typically feature a swing-arm hinge with the pivot pin mounted in the door frame. Typically, the swing-arm box and door frame are welded together, preventing spatial adjustment and creating an unsuitable structure. Consequently, door leaf installation and commissioning are complex. This is particularly true for aluminum alloy door frames, where the swing-arm box cannot be welded to the door frame. Therefore, developing a three-dimensionally adjustable swing-arm hinge suitable for aluminum alloy door frames, capable of being disassembled, easy to assemble and commission, and easy and flexible to open without noise, while also being able to withstand heavy door leaves, is becoming increasingly important.
