Embodiment
Please referring to shown in Fig. 1,2,3, inflator of the present utility model includes:
Two ends are respectively equipped with opening 11,12 and inside is the body 10 of hollow;
Columned push rod pressure meter 30, be provided with most scales 31 that show the pressure size thereon, be provided with relative projection 32 with respect to L shaped groove 21 places on it, pressure meter 30 downsides are provided with short slot 33, near pressure meter 30 downsides annular groove 34 is set, in a check valve 35, one Returnning springs 36 wherein are set, it is arranged between the inwall of pressure meter 30 outsides and body 10;
Hollow shape gas tube 40 with suitable length penetrates in the pressure meter 30, and gas tube 40 downsides are fixedly arranged on opening 11 places of body 10, gas tube 40 outside sheathed sleeve pipes 401, one spring 41 is sheathed on gas tube 40 and sleeve pipe 401 outsides, and its upside and pressure meter 30 downsides are fixed;
Check valve connecting rod 42 is fixed at gas tube 40 upsides, and its inside has the aperture 43 of upper and lower perforation, and ring is established annular groove 44 on it, and annular groove 44 inside are provided with a check valve 45;
The valve chock 50 of T-shaped section is fixedly arranged on pressure meter 30 upsides, is provided with in-line groove 52 in the upper surface of valve chock 50, and this in-line groove 52 can make itself and pressure meter 30 rotate in the lump by tool using;
As Fig. 2, shown in Figure 3, the utility model is when using, inflator of the present utility model can be arranged at and be inflated thing 70 inside, capping 20 is fixedly set in respectively with body 10 upsides and is inflated thing 70 inside, valve chock 50 just is arranged at and is inflated on the thing 70, when using, can stretch into in-line groove 52 places that are provided with on the valve chock 50 by instrument, rotate valve chock 50 again and make push rod pressure meter 30 interlock in the lump, and can make the projection 32 that is provided with on the push rod pressure meter 30 break away from the L shaped groove 21 of capping 20 inboards (as Fig. 1, shown in Figure 4), since be inflated thing 70 gas inside, can be via gas tube 40,42 conductings of check valve connecting rod are located to the space between chock 60 downsides and the pressure meter 30;
When being inflated thing 70 gas inside pressure greater than the spring power of Returnning spring 36, can make push rod pressure meter 30 with respect to body 10, capping 20 be inflated thing 70 slightly towards extrapolation (as Fig. 5, shown in Figure 6), because push rod pressure meter 30 is provided with the scale 31 that shows the pressure size, can show and be inflated scale 31 places of thing 70 gas inside pressure in pressure meter 30, the people is understood be inflated thing 70 gas inside pressure sizes with when for referencial use, so that decision will to charge into the amount of gas many or few to being inflated thing 70, when charging into gas to being inflated thing 70, only push rod pressure meter 30 constantly need be pushed away with respect to body 10, pulling is done, be used as the action that pushes away, can make gas by pressure meter 30 downsides through spring 41, gas tube 40 outsides, check valve 45 enters aperture 43 places of check valve connecting rod 42 inside up, charge into through gas tube 40 again and be inflated thing 70 inside, when being used as the action of drawing, can make extraneous air through capping 20, pressure meter 30 outsides, short slot 33, check valve 35 enters the place, space between pressure meter 30 downsides and the body 10, the utility model constantly charges into and is inflated thing 70 inside so that be inflated the gas of thing 70 outsides, so can provide suitable aeration to being inflated thing 70.
As Fig. 7, shown in Figure 8, major part is same as Fig. 1, structure shown in Figure 2, the utility model also can be made into independent pattern, be inflated thing inside but not be arranged at, its difference is in: the body 10 in the utility model also can be provided with screw thread 13 in its place, end, and this screw thread 13 can screw togather mutually for the screw section 81 that is provided with on a ball pin 80, uses for being used as pump, equally, can reach being inflated the purpose that thing 70 is suitably inflated.
Therefore, via above explanation as can be known, the utility model have at least as after advantage;
Because the aerating device in the utility model is provided with push-down pressure gauge 30, this pressure gauge 30 can show Be inflated thing 70 internal gas pressure sizes, so that inflation is used, when inflation, this aerating device can To inflate being inflated thing 70; This aerating device also can be made into independent pattern, in its end ball pin 80 is set, The inflator that also can be used as being inflated thing 70 inflation uses, and have can be to being inflated so the utility model possesses Thing inflation with show the dual-use function that is inflated thing internal gas pressure size, also have easy to use excellent The point.
