Description

A kind of aerated tube

The utility model relates to a kind of inflator pump.

At present, manually inflator pump is commonly two kinds of leather cup formula, storage pot types, and working life is short, greasy dirt is more unhygienic, and easily make dirty hand and clothing are also very disagreeable during dismounting, greasy dirt enters and easily causes corrosion in the tire during inflation, influences the working life of tire, and what have changes leather cup into piston, though prolong working life to some extent, but still need to refuel, the problem that greasy dirt brings is not resolved, and encapsulation is poor, have the gas backstreaming phenomenon to take place, the inflation effect is low, wastes time and energy.

The purpose of this utility model provides a kind of reasonable in design, long service life, and encapsulation is strong, good charging, the reliable inflator pump of health.

For solving above-mentioned task, the solution that the utility model adopts is: inflator is made up of inside and outside two inflators, outer inflator and handle are connected to a fixed, handle is streamlined, outer inflator lower end is provided with outer cover, interior inflator top is provided with piston, bottom and base are connected to a fixed, the propelling that lifts by handle moves up and down outer inflator, and gas storage is finished by interior inflator, and base is provided with transverse conduit, one end is provided with tapping screw, the other end is connected with inipple, the band of gas, valve cock in turn, and the band of gas is folded on the handle, and base bottom one side is provided with foot-operated.

The solution that the utility model also adopts is: inside and outside inflator is made with metallic material; Also can be provided with the centre lathe type special fixture on the valve cock.

The utility model has following advantage compared to existing technology:

1, reasonable in design, good reliability, long service life.

2, sealing is strong, and good charging prevents gas backstreaming, and is time saving and energy saving.

3, applied widely, because inflation pressure is big, not only is applicable to manpower bicycle, tricycle Tyre inflating, and also can uses that only need join gets final product with the centre lathe type special fixture to cycle tyre, agricultural tricycle tire, automobile tire.

4, health is clean, need not refuel during use, thereby can greasy dirt hand and clothing, easy accessibility, nonhygroscopic, non-corrosive does not corrode tire yet, keeping easy to store.

5, adopt aluminum alloy material to make outer inflator, thus little, aesthetic in appearance, easy to carry from heavy and light, volume.

Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail:

Fig. 1 is the plan view of inflator pump;

Fig. 2 is a sectional view shown in Figure 1.

As Fig. 1, shown in Figure 2, it includes interior inflator 10, outer inflator 11, handle 1, base 2, foot-operated 3, inipple 4, clamp folder 5, the band of gas 6, band of gas folder 7, valve cock 8, piston 9, interior inflator 10 usefulness seamless steel pipe materials are made, outer inflator 11 usefulness aluminum alloy material are made, outer inflator 11 tops and handle 1 are fixedly connected, handle 1 is streamlined, outer inflator 11 bottoms are provided with outer cover 12, interior inflator 10 tops are provided with piston 9, piston 9 tops are provided with annular groove 13 with outer inflator 11 inwall adjacent portions, following annular groove 14, annular groove 13 up and down, be respectively equipped with O-ring seals 15 on 14,16, be provided with valve body 17 in the middle of the top of piston 9, be equipped with circular groove 18 outside the top of valve body 17, which is provided with seal ring 19, be provided with spool 20 in the middle of the valve body 17, interior inflator 10 bottoms are fixed on the base 2, base 2 middle parts are provided with transverse conduit 21, transverse conduit 21 1 ends are provided with tapping screw 22, tapping screw 22 is provided with seal ring 23, transverse conduit 21 middle parts communicate with interior inflator 10, transverse conduit 21 the other ends vertically are connected with inipple 4, inipple 4 is connected with the band of gas 6 in turn, valve cock 8, and the inipple 4 and the band of gas 6 are folded firmly by clamping folder 5, band of gas folder 7 is located on the handle 1, base 2 bottoms one side is provided with foot-operated 3, being provided with hole clipping by the base both sides links to each other with foot-operated 3, also be provided with the centre lathe type special fixture on the valve cock 8, be used for motorcycle, motor tricycle, automobile tyre inflation.
