The utility model discloses a diaphragm assembly of a pneumatic diaphragm pump, which comprises a diaphragm, one side of the diaphragm is provided with a threaded connecting rod, the threaded connecting rod is connected with the diaphragm through a fastening mechanism, and the outer ring of the diaphragm is fixedly connected with a convex ring. The diaphragm assembly has the beneficial effects that through the fastening mechanism arranged on the threaded connecting rod, the diaphragm can be elastically pressed through the pressing assembly, the situation that the diaphragm is excessively extruded to be damaged, and consequently the physical performance is reduced can be avoided while the connecting sealing performance is guaranteed, and through the arranged convex ring, when the diaphragm and the pump body are assembled, the diaphragm is not prone to being damaged; a traditional screw fixing and positioning mode is omitted, the diaphragm is prevented from loosening through limitation of the convex ring, force
