Abstract
A portable inflator comprises a tube body, a piston rod, an air faucet and a handle, wherein, an inner tube body is arranged in an outer tube body; the inner tube body can slip in the outer tube body; the inner tube body is provided with an opening communicating the inner tube body with the outer tube body; the piston rod is arranged in the inner tube body; the piston rod can slip in the inner tube body; the ends of the inner tube body and the piston rod are respectively provided with a ring-shaped groove for placing a sealing ring; the other end of the piston rod is connected with the handle; the lower part of the outer tube body is connected with the air faucet; the conduits of the ring-shaped grooves at the ends of the inner tube body and the piston rod close to an air outlet are respectively provided with a gap. The inflator is high in air outlet pressure, which can inflate tires. The air faucet is a multipurpose air faucet, and the inflator is provided with a clamping part, which makes the inflator convenient to be carried.
Description
Technical field:
The utility model relates to a kind of inflatable tool, particularly a kind of inflator of the out using that is easy to carry.
Background technique:
At present, inflator generally is made of cylindrical shell, piston rod, valve, handle.Barrel diameter and length are all fixed, and make the higher air pressure of inflator output, need with long cylindrical shell, and longer inflator are not easy to go out to carry with car.Carry for conveniently going out, some Miniature inflaters occurred, its volume is small and exquisite, but the output pressure of Miniature inflater is lower, and the gas output of inflation cycle is very little each time, is unsuitable for tire is inflated.
Summary of the invention:
Carry inconvenient defective more greatly for solving existing inflator volume, the inventor proposes the bigger portable inflator of a kind of gas output.It comprises: cylindrical shell, piston rod, valve, handle; Be provided with inner barrel in the outer cylinder body, inner barrel can slippage in outer cylinder body, and inner barrel is provided with the perforate that inside and outside cylindrical shell is communicated with; Be provided with piston rod in the inner barrel, piston rod can slippage in inner barrel; The end of inner barrel and piston rod respectively is provided with the annular groove that is used to settle seal ring, and the other end of piston rod is connected with handle, and the outer cylinder body bottom links to each other with valve.During use, handle drives piston rod movement, and the gas of inner barrel is expressed in the outer cylinder body; Simultaneously, handle drives inner barrel, and the gas in the outer cylinder body is charged into tire.Because inflator is provided with two cylindrical shells of slippage relatively, make the exportable higher air pressure of inflator.After the use, handle is pressed onto the end, the volume of inflator is small and exquisite, is convenient to go out to carry.In the utility model, inner barrel and piston rod end annular groove have breach near the conduit of air outlet.When handle is pulled out, do not have sealing between seal ring and barrel; When handle presses down, between seal ring and barrel sealing intact, make inflator reliable operation, simple in structure.
In the utility model, valve preferably more uses valve, makes inflator to inflate cycle tyre, cycle tyre, ball etc.Inflator is preferably with fastener, and inflator is snapped in the fastener, and fastener is loaded on the bicycle, carries more convenient.
Description of drawings:
Fig. 1 is the utility model embodiment 1 handle schematic representation when pulling out.
Fig. 2 is the utility model embodiment 1 handle schematic representation when takeing in.
Fig. 3 is the utility model valve portion enlarged diagram.
Fig. 4 is the utility model inner barrel annular groove section enlarged diagram.
Fig. 5 is the utility model embodiment 2 schematic representation.
Embodiment:
Shown in Fig. 1-4, the inflator of present embodiment comprises: piston rod 1, valve 2, handle 3; Be provided with inner barrel 5 in the outer cylinder body 4, inner barrel 5 can slippage in outer cylinder body 4, and inner barrel is provided with the perforate 6 that inside and outside cylindrical shell is communicated with; Be provided with piston rod 1 in the inner barrel 5, piston rod 1 can slippage in inner barrel; The end of inner barrel and piston rod respectively is provided with the annular groove that is used to settle seal ring 7, and piston rod is connected with handle, and the outer cylinder body bottom links to each other with valve.During use, the exportable higher air pressure of inflator; After packing up, the volume of inflator is small and exquisite.Inner barrel and piston rod end annular groove have breach 8 near the conduit of air outlet.Make inflator structure simple.Inflator has figure of eight fastener 9, makes easy to carry.Valve is to use valve more, can be to cycle tyre, cycle tyre, the ball inflation.
Fig. 5 has provided the utility model embodiment 2.In the present embodiment, valve also is to use valve more, and handle has folding structure, and the fastener of inflator can directly be loaded on the bicycle.
Claims (4)
