Description

Technical Field

[0001] The utility model relates to the technical field of hardware, in particular to an adjustable hinge with a lubrication structure. Background Art

[0002] Hardware hinges are components that connect doors and windows for opening and closing. Depending on their usage scenarios, load capacity, and opening and closing range, their specific design structures also vary greatly. Currently, many heavy-load hinges on the market are designed to be adjustable, mainly to meet the differences in slot accuracy during actual installation. This allows them to meet actual installation requirements when the hole position cannot be changed on site.

[0003] When this type of hinge is in use, in order to meet the needs of heavy loads, the door panel width is also large, and a large opening and closing range is required. Therefore, the hinge usually adopts a three-point support design. While the two parts of the hinge body rotate, its inner support leg slides on the opposite side to support and prevent the hinge from deforming. However, the current technical solution is to design a slide rail or a slide groove so that the support leg of the hinge slides in the slide groove. During use, in order to reduce noise and increase service life, it is usually necessary to add lubricating oil regularly. The effective lubrication time is short and frequent addition is required, which is more troublesome. For this purpose, an adjustable hinge with a lubrication structure is specially provided.
