The utility model is achieved in that a kind of bi-directional compression inflator, comprises base, inner barrel, outer cylinder body, handle, push rod, and the push rod that the bottom has lower piston is connected the handle bottom; Described outer cylinder body is connected on the handle, and the outer cylinder body top is provided with suction port; Inner barrel is placed in the outer cylinder body inboard, and inner barrel links to each other with base, and the inner barrel bottom is provided with the one-way valve that passes to the air outlet, surrounds the annular center air cavity between inner barrel and the push rod; The outer cylinder body bottom is socketed on the inner barrel outer wall by bottom is airtight, and the top that the outer cylinder body middle part is positioned at the inner barrel top is provided with upper piston, leaves the marmon clamp gas-bearing formation between outer cylinder body and the inner barrel; The inner barrel top is provided with opening, is communicated with annular central gas chamber and marmon clamp gas-bearing formation; The upper piston center is provided with the through hole identical with the push rod external diameter, the upper piston bottom surface links to each other with inner barrel, the upper piston external diameter is slightly less than the outer cylinder body internal diameter, have inwardly recessed draw-in groove in the upper piston periphery, be provided with slightly larger in diameter in the draw-in groove in the O of outer cylinder body internal diameter shape loose gland, have the gas-entered passageway that passes to the marmon clamp gas-bearing formation on the draw-in groove of seal ring below; Push rod passes the upper piston central through bore, the lower piston that push rod connects is arranged at the inner barrel inboard, the lower piston external diameter is slightly less than the inner barrel internal diameter, have inwardly recessed draw-in groove in the lower piston periphery, be provided with slightly larger in diameter in the draw-in groove in the O of inner barrel internal diameter shape loose gland, have the gas-entered passageway that passes to inner barrel on the draw-in groove of seal ring below.
Described upper piston is inboard to be provided with seal ring with the push rod joint.
Described outer cylinder body bottom and inner barrel joint are provided with seal ring.
Described O shape loose gland inboard is provided with spacing snap ring.
The utility model is because employing has double-deck cylindrical shell, can effectively utilize push rod institute's work in two processes of push-and-pull, O shape loose gland can be regulated and control the turnover of air-flow at each chamber effectively, and is simple and reasonable, laborsaving when using the utility model to inflate.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the push rod 13 that the bottom has lower piston 4 is connected handle 1 bottom, and outer cylinder body 3 is connected on the handle 1, and outer cylinder body 3 tops are provided with suction port 12; Inner barrel 5 is placed in outer cylinder body 3 inboards, and inner barrel links to each other with base 6, and the inner barrel bottom is provided with the one-way valve 8 that passes to air outlet 7, surrounds annular center air cavity 18 between inner barrel 5 and the push rod 13; Outer cylinder body 3 bottoms are by bottom 20 airtight being socketed on inner barrel 5 outer walls, and the top that the outer cylinder body middle part is positioned at the inner barrel top is provided with upper piston 2, leaves marmon clamp gas-bearing formation 14 between outer cylinder body and the inner barrel; The inner barrel top is provided with opening 19, is communicated with annular central gas chamber and marmon clamp gas-bearing formation; The upper piston center is provided with and the identical through hole of push rod 13 external diameters, the upper piston bottom surface links to each other with inner barrel, the upper piston external diameter is slightly less than the outer cylinder body internal diameter, have inwardly recessed draw-in groove 15 in the upper piston periphery, be provided with slightly larger in diameter in the draw-in groove 15 in the O of outer cylinder body internal diameter shape loose gland 9, have the gas-entered passageway 16 that passes to marmon clamp gas-bearing formation 14 on the draw-in groove of seal ring below; Push rod 13 passes the upper piston central through bore, the lower piston 4 that push rod connects is arranged at the inner barrel inboard, lower piston 4 external diameters are slightly less than the inner barrel internal diameter, have inwardly recessed draw-in groove 15 ' in the lower piston periphery, be provided with slightly larger in diameter in the draw-in groove 15 ' in the O of inner barrel internal diameter shape loose gland 9 ', have the gas-entered passageway 16 ' that passes to inner barrel pressure air cavity 17 on the draw-in groove of seal ring 9 ' below.Upper piston 2 inboards are provided with seal ring 10 with the push rod joint.Outer cylinder body bottom 20 is provided with seal ring 10 ' with the inner barrel joint.O shape loose gland 9 and 9 ' inboard are respectively equipped with spacing snap ring 11 and 11 '.
When making progress pull handle, outer cylinder body 3 moves upward thereupon, and the O shape loose gland 9 in the draw-in groove 15 of upper piston 2 is upwards taken up, and seals the gap between upper piston 2 and the marmon clamp gas-bearing formation 14, marmon clamp gas-bearing formation 14 volumes reduce thereupon, and air therebetween is pressed into annular center air cavity 18; Meanwhile, lower piston 4 is with moving on the push rod, downward relative displacement takes place in the O shape loose gland 9 ' in the draw-in groove 15 ' of lower piston 4, annular center air cavity 18 is communicated with inner barrel pressure air cavity 17, inner barrel pressure air cavity 17 volumes increase pressure and reduce, and the air in marmon clamp gas-bearing formation 14 and the annular center air cavity 18 is pressed into inner barrel pressure air cavity 17; When handle was finished to top offset, air compression was also finished for the first time.
