The invention belongs to the field of hardware fittings and relates to a hinge facilitating lubricating oil charging and storage. The hinge comprises a mandrel (1) and two hinge plates (2), wherein the two hinge plates (2) are provided with mandrel sleeves and arranged on the mandrel (1) in a sleeving manner. Multiple axial oil storage grooves (3) are formed in the side face of the mandrel (1) in the axial direction. Each axial oil storage groove (3) is internally provided with an oil absorption strip matched with the corresponding groove. Radial oil storage grooves (4) are formed in the side face of the mandrel (1) in the radial direction. Each radial oil storage groove (4) is internally provided with an oil absorption ring matched with the corresponding groove. The axial oil storage grooves (3) and the radial oil storage grooves (4) are connected in a cross manner. Oil injection holes (5) are formed in the mandrel sleeves of the hinge plates (2). By means of the hinge, it can be convenient to charge lubricating oil to the hinge, and the lubricating oil can be stored, so that it is guaranteed that the hinge is lubricated for a long time; and trouble caused by frequent lubricating oil charging is reduced.
