Abstract

The utility model relates to a high pressure portable air cylinder, which belongs to a non-variable volume pump. The utility model comprises a cylinder body, a spring, a one-way valve, a spacing ring, a rubber bowl and a piston. The utility model is characterized in that one end of a connecting lever is connected with the piston, and the other end of the connecting lever is connected to the middle part of a handle. The connecting lever can relatively rotate with the piston and can also relatively rotate with the handle. A lock shaft which is fixed on the top end of the cylinder body passes through the top end of the handle, and the handle can rotate around a pin shaft. The cylinder body is provided with a slot where the handle is pressed down. The utility model has the advantages of simple structure, and easy portability, and convenient use. The volume is about one half of the volume of the original air cylinder, and the utility model can be carried and used at any time. The high pressure structure is adopted, and the pulling and the pressing of the handle are convenient.

Description

High pressure portable air pump

The utility model relates to a kind of high pressure Miniature inflater, belongs to a kind of non-varactor pump.

The present inflator that uses is large-scale, carries inconvenience, when cycling on the way leaks gas, can't inflate, and brings very big inconvenience to people; Chinese patent CN2073046U has announced a kind of " Miniature inflater ", adopts the piston perisporium to offer piston ring, and the labour through hole is opened at the middle part, and one-way valve is set, and its shortcoming is: complex structure, use inconvenient.

The high pressure Miniature inflater that provides a kind of volume little, easy to carry, simple in structure, easy to use is provided the purpose of this utility model.

In order to achieve the above object, the utility model adopts following technological scheme: a kind of high pressure Miniature inflater, and it comprises cylindrical shell, spring, one-way valve, spacer ring, rubber cup and piston is characterized in that: bar one end connects piston, and the other end is connected in the middle part of handle; All can rotate relatively between bar and the piston, bar and handle; The bearing pin that is fixed on the cylinder top passes from the top of handle, and handle can rotate around bearing pin; Have the groove of depressing for handle on the cylindrical shell.Therefrom air inlet after groove long enough to piston is come by handle, bar band.When the handle pull-up, bar drives piston and moves, and gas enters from groove, and when handle was depressed, bar promoted the piston reverses direction motion, blocks groove and the gas that enters is pressed into high-pressure chamber and enters tire by one-way valve.

The utility model compared with prior art has following advantage:

1, simple in structure, volume has only about 1/2 of original inflator, can carry, and uses at any time;

2, easy to use, adopt high voltage structures, the handle pull-up is depressed conveniently.

Fig. 1 is the utility model structural representation;

Fig. 2 is the plan view of Fig. 1.

The utility model is described in further detail below in conjunction with embodiment:

The utility model is by cylindrical shell (5), end cap (1) and spring formations such as (2), the end of cylindrical shell (5) is provided with the end cap (1) that can give vent to anger, spring (2) one ends withstand on the cylindrical shell (5) by end cap (1), the other end withstands one-way valve (3), spacer ring (4) is fixed on the cylindrical shell (5), an aperture is established in the centre, block by one-way valve (3), piston (7) is located at the middle part of cylindrical shell (5), be fixedly connected with rubber cup (6) by terminal, piston (7) by head portion have one the projection be connected with bar (8), the other end of bar (8) is connected in the middle part of handle (9); All can rotate mutually between bar (8) and piston (7), bar (8) and the handle (9); The bearing pin (10) that is fixed on cylindrical shell (5) top passes from the top of handle (9), and handle (9) can rotate around bearing pin (10); Have the groove of depressing for handle (9) (11) on the cylindrical shell (5).The utility model optimum implementation is: cylindrical shell (5) length overall 285mm, and wide 39mm, the long 125mm of groove (11), the long 55mm of spring, other position is relative set then.

The air inlet function of the utility model groove (11) also can adopt and drive pore into replace on cylindrical shell (5).

Claims

1, a kind of high pressure Miniature inflater, it comprises cylindrical shell, spring, one-way valve, spacer ring, rubber cup and piston is characterized in that: bar (8) one ends connect piston (7), and the other end is connected in the middle part of handle (9); All can rotate relatively between bar (8) and the piston (7), bar (8) and handle (9); The bearing pin (10) that is fixed on cylindrical shell (5) top passes from the top of handle (9), and handle (9) can rotate around bearing pin (10); Have the groove of depressing for handle (9) (11) on the cylindrical shell (5).

2, high pressure Miniature inflater according to claim 1 is characterized in that: therefrom air inlet after groove (11) long enough to piston (7) is come by handle, bar (8) band.
