Description

Adjustable hinge with bearing Technical Field The utility model belongs to the field of building hardware, and particularly relates to an adjustable hinge with a bearing. Background Hinges are devices used for connection or rotation whereby a door, cover or other swinging member may be rotated to open or close, typically consisting of a pair of metal leaf bushings pinned together. At present, a hinge conventionally used in the market generally consists of two hinge plates, a pin shaft and a gasket, and the hinge is arranged on a door and window sash and a door and window frame through screws. However, for heavy doors and windows with larger door and window wings, the conventional hinge structure can cause the door and window wings to sink and incline to land due to gravity after long-time use, so that normal use cannot be continued. In addition, the existing hinges are fixedly connected and cannot be adjusted after production is completed, so that certain requirements are met on production precision and installation precision of products, such as doors and windows, using the hinges and the hinges, fault tolerance is low, and once dimensional deviation occurs, the hinges need to be detached and installed again, and installation efficiency and installation quality are affected. Therefore, the Chinese patent publication No. CN216076749U discloses a high-bearing adjustable hinge, which can adjust the distance between a second hinge and a vertical adjusting seat by rotating a vertical adjusting bolt to realize up-and-down fine adjustment, and can adjust the swinging angle of an eccentric shaft sleeve by rotating a horizontal adjusting bolt to realize left-and-right fine adjustment so as to solve the problems. However, after the hinge structure is used for a long time, the rotating part of the hinge structure is easy to be blocked due to the lack of lubricating oil, so that the use experience is affected, the service life is shortened, and the hinge structure is particularly obviously affected when being applied to scenes such as heavy doors and windows which are easily affected by friction factors, so that frequent maintenance is required, and the maintenance cost is high.
