Novel diaphragm pump

The utility model discloses a novel diaphragm pump, including main part and landing leg, both sides all are provided with the air chamber about the inner chamber of main part, the department installsthe diaphragm, two in the middle of the inside wall of air chamber install the transmission shaft between the diaphragm, input port and delivery outlet have been seted up respectively to the left andright sides wall of main part. This novel design benefit facilitates the use, through change the piece, down the landing leg cooperation of moving, adjust the landing leg use, can make the diaphragm pump subaerial at the environment of difference, can both steadily place, play the effect of shock attenuation buffering through the second spring, reduce vibrations and lead to the fact the harm to the diaphragm pump, cooperation through first spring, dog, through -hole isotructure is used, and when preventing that the pump internal pressure is too big, the outlet pipe is burst and the work that influences by water pressur
