The invention belongs to the field of hardware fittings and relates to a hinge provided with oil storage grooves and facilitating lubricating oil filling. The hinge is composed of a central spindle (1) and two hinge plates (2) with shaft sleeves, and the central spindle (1) is sleeved with the hinge plates (2). A plurality of axial oil storage grooves (3) are formed in the side face of the central spindle (1) in the axial direction. One radial oil storage grooves (4) is formed in the side face of the central spindle (1) in the radial direction. The radial oil storage grooves (4) and the axial oil storage grooves (3) are connected in a crossed mode. An oil filling hole (5) is formed in the shaft sleeve of one hinge plate (2). The hinge provided with the oil storage grooves and facilitating lubricating oil filling facilitates filling of lubricating oil. Lubricating oil can be stored through the oil storage grooves to guarantee lasting lubrication of the hinge. The trouble caused by frequent lubricating oil filling is reduced.
