description The utility model provides a knob lock assembly used for a centrifugal machine cover, which comprises a knob shaft (3) configured to penetrate into a centrifugal machine upper plate (5), and at least one part of the lower end of the knob shaft (3) is provided with a lead screw thread; the knob (1) is fixed with the upper end of the knob shaft (3); the lead screw nut (6) is in threaded fit with a lead screw at the lower end of the knob shaft (3), so that rotation of the knob shaft (3) causes the position of the knob shaft (3) in the vertical height to change, the side face of the upper end of the knob shaft (3) is provided with a conical profile, and the side, facing the knob shaft (3), of the knob (1) is provided with a conical hole, so that the knob shaft (3) and the knob (1) are matched through a conical surface. The knob lock assembly for the centrifugal machine cover can prevent loosening or slipping between the knob and the knob shaft, has low machining difficulty and machining cost, and can assist a use
