Abstract
The utility model discloses a high-pressure inflator composed of an air storage tube, an inflating tube, a base, a valve seat connecting the air storage tube and the inflating tube, a piston, an inflating bar, a handle and an air-conveying tube assembly. The utility model is characterized in that the air storage tube and the inflating tube are arranged in the same axial line, and the valve seat connecting the air storage tube and the inflating tube is provided with a one-way ball-valve; besides, the piston has a double-lip opening. Compared with the existing inflator, the inflator has the lowered production-cost, the improved performance, and simple process.
Description
The utility model relates to a kind of novel high-pressure pump.
Now the gas cylinder of selling on the market all is air-storage chamber to be placed inflate the next door of chamber.The air-storage chamber of this inflator adopts rich enclosed construction.Need divide three to five processes by friction screw press more than 60 tons, compression molding, in addition, inflate chamber and the air-storage chamber of this inflator are arranged on the same base, make understructure bigger, and add and need use several special fixtures man-hour, therefore, this inflator manufacture difficulty is bigger, and cost is higher.And this inflator adopts the piston of single lip, the long-term use, and piston is quick-wearing very, can not use at last.
The purpose of this utility model is at above-mentioned deficiency, proposes a kind of novel high-pressure pump, reduces the manufacture difficulty and the cost of production of gas cylinder, and makes piston obtain prolonging working life.
Be described in detail technology contents of the present utility model below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model:
1 is foot-operated among the figure, the 2nd, and base, the 3rd, gas-storing pipe, the 4th, ball valve, the 5th, valve seat, the 6th, stifle, the 7th, piston, the 8th, air-inflating tube, the 9th, inflating rod, the 10th, pneumatic tube assembly, the 11st, cover, the 12nd, handle.
As shown in drawings, the utility model is by gas-storing pipe 3, air-inflating tube 8, base 2, and the valve seat 5 of connection gas-storing pipe 3 and air-inflating tube 8, piston 7, inflating rod 9, handle 12 and appendix assembly 10 form. Gas-storing pipe 3 and air-inflating tube 8 connect together by valve seat 5 on same axis, and gas-storing pipe 3 is positioned at the below of air-inflating tube 8. Appendix assembly 10 links to each other with valve seat, and the passage of a connection gas-storing pipe 3 and air-inflating tube 8 is arranged on the valve seat 5, and this passage is perpendicular "the" shape, is provided with a ball valve 4 in the middle of passage. Piston 7 is when pressing down, and check valve 4 is opened, when carrying on the piston 7, and closed check valve. Input pipe assembly 10 communicates with gas-storing pipe. Piston 7 is designed to the double-lip symmetric figure, by abrasive rubber hot-cast moulding, can use conversely another lip after an one lip one decreases.
Use principle of the present utility model is such:
Hold handle 12, with piston 7 to pressing down, build-up pressure in air-inflating tube 8, during pressure, ball valve 4 is backed down in pressure in it is a bit larger tham gas-storing pipe 3, air enters gas-storing pipe 3, enters bicycle inner tube by pneumatic tube assembly 10 then.When carrying on the piston 7, air-inflating tube 8 decompressions, ball valve is fallen into hermetically sealed can by deadweight, and the air in the air-storage chamber must not be refluxed.So, move in circles, very fast tire is filled with pressurized air.
The utlity model has following technical characterstic and using effect:
1, base 2 is centrosymmetric rotary work piece with valve seat 5, and its processing technology is very simple, need not special fixture at all, and materials also greatly reduce, so cost of production greatly reduces.
2, gas-storing pipe is the steel pipe of a list, only needs common machining to make, and does not need special device, produces investment so can significantly reduce, thereby saves cost of production.
3, replace the plane valve with ball valve, overcome because of plane valve back pressure makes greatly and inflated the fraud of effort, and unlatching and seal all reliable than the plane valve, thereby improved the performance of pump.
4, adopt lips mouth piston, replace single lip piston, make the life-span of piston prolong one times like this, also can increase the sealability of piston.
Claims (2)
1, a kind of high-pressure pump, it is made up of valve seat, piston, inflating rod, handle and the pneumatic tube assembly of gas-storing pipe, air-inflating tube, base, connection gas-storing pipe and air-inflating tube, it is characterized in that gas-storing pipe and air-inflating tube are on same axis, connect gas-storing pipe and air-inflating tube, valve seat is provided with a ball valve.
2, the high-pressure pump of narrating according to claim 1 is characterized in that piston is the lips mouth.
