A pump structure easily and quickly connectable with an air cushion or a bladder. The pump structure includes a flexible main body defining a cavity. The main body is compressible and decompressible to reciprocally contract and expand the cavity for pumping a fluid. A one-way valve is mounted on a wall of the cavity, permitting external fluid to one-way flow into the cavity. A check valve and an output tube are connected with the main body. A conduit with a deflation valve is disposed on the flexible main body and communicates with the output tube to form a deflation passage. The output tube is selectively easily connectable with an air cushion or a bladder, whereby the fluid can be pumped from the cavity through the output tube into the air cushion or the bladder.
