Abstract
The utility model provides a high-pressure inflator, comprising a handle (1). The upper end of a piston rod (3) is installed on the handle. A leather cup (9) is arranged at the lower end of the piston rod in the outer shell of an inflator (7). A valve seat (12) is installed at the upper part of an outer shell of an air storage bag (10). A spring (15) is arranged below the valve seat. A spring (14) is installed on the spring seat. A valve is fixed on the spring. A U-shaped threaded rod (6) is installed between a base (18) and a nut (4) which passes through an upper pressing cover (5). The outer shell of an inflator (7) and the outer shell body of an air storage bag (10) are fixed together, and the outer shell of an inflator (7) and the outer shell body of an air storage bag (10) are positioned on the same axial cord. The utility model has the advantages of simple structure, compact structure, easy fabrication, force-saving inflation and long service life. The connecting points can not be damaged easily.
Description
The utility model provides a kind of inflator device toward bicycle tyre or the interior inflation of other article.
Present widely used inflator device (pump), a kind of is not to be with the air storage bag, simple in structure, long service life, but inflation effort; Another kind has the air storage bag, inflate laborsaving, but since air storage bag and inflator install side by side, therefore, complex structure, not compact, make difficultly, and the threaded connection place of air cylinder casing and base is easily damaged because of slide fastener.
The purpose of this utility model is that to provide a kind of inflation laborsaving, simple in structure, and each joint is not fragile, the gas cylinder of long service life.
The utility model is to realize like this, it includes the handle that is installed in stopper rod top, air cylinder casing is interior, the bottom of stopper rod is fixed with leather cup, the top of air storage ladle shell is equipped with valve seat, under the valve seat spring seat is arranged, and spring is housed on the spring seat, be fixed with valve on the spring, by nut the U-shaped screw rod is installed between base and upper press cover, air cylinder casing and air storage ladle shell are fixed together, and both are on same the axis.
Adopt the gas cylinder of said structure, owing to air storage ladle shell and air cylinder casing are fixed together and are on same the axis, make the overall structure of inflator simple, compact.Because its base only connects the air storage bag, therefore make simple.Owing to adopted the U-shaped screw rod to clamp, so each joint is not fragile.This gas cylinder had both overcome the shortcoming of not requiring great effort with the inflator inflation of air storage bag, had solved the flimsy problem in inflator threaded connection place of band air storage bag again.
Below in conjunction with description of drawings concrete structure of the present utility model.
Accompanying drawing is the schematic representation of the utility model structure.
As shown in drawings, on the gas cylinder of the utility model, handle (1) is arranged, stopper rod (3) upper end is fixed together with handle, air cylinder casing (7) is interior, the lower end of stopper rod is fixed with leather cup (9), air storage ladle shell (10) upper end is equipped with valve seat (12), spring seat (15) is arranged under the valve seat, spring (14) is arranged in the spring seat, be fixed with valve (13) on the spring, by nut (4) U-shaped screw rod (6) is installed between base (18) and upper press cover (5), air cylinder casing (7) is fixed together with air storage ladle shell (10), and is on same the axis.
Outside the stopper rod of upper press cover (5) top spring (2) can be arranged, can there be spring (8) the stopper rod outside of leather cup (9) top, with the protection leather cup.Between air cylinder casing (7) and valve seat (12), seal washer (11) can be arranged, between air storage ladle shell (10) and base (18), seal ring (16) can be arranged.On base (18), also be equipped with foot-operated (17).
When leather cup moved down inflation in inflator, valve (13) was washed open, and gas enters by the air storage bag and is inflated object; When leather cup moved up, valve was closed, and unnecessary gas is compressed in the air storage bag.When inflating once more, because the leather cup sectional area is far longer than the sectional area of valve, so the gas in the inflator can be compressed in the air storage bag very effortlessly, gas enters through the air storage bag and is inflated object.
Claims (1)
