A plastic pressure vessel structure includes a diaphragm mounted in a plastic outer barrel for dividing the plastic outer barrel into an upper chamber containing a liquid, and a lower chamber containing a pressurized gas, and a plastic inner barrel fully mounted in the lower chamber. In such a manner, the wall of the inner barrel and the wall of the lower chamber are overlapped with each other, such that capillary pores of the wall of the inner barrel and capillary pores of the wall of the lower chamber are arranged in a staggered manner, thereby reducing the capillary action, so as to provide a tight sealing effect in the lower chamber, thereby preventing the pressurized gas contained in the lower chamber from leaking outward, and thereby preventing the pressure contained in the lower chamber from being reduced.
