Abstract
The invention provides a valve core pile. A shaft lever arranged in an air intake pile and connected with a tyre integrally is sleeved with a spring, the upper end of the shaft lever is provided with a piston, the exterior of the air intake pile is screwed with an inflated screw cap the top of which is provided with an inflation inlet, and the interior of the inflated screw cap is provided with a gasket sealed with the piston in the air intake pile. The valve core pile can completely block an air valve so as not to leak air after the tyre is inflated, and an inner core is quite convenient to assemble, disassemble and replace.
Description
Affiliated technical field
The present invention relates to the used inflation stake of a kind of tire, a kind of specifically valve inside pile.
Background technique
At present, the used valve inside pile of tire has multiple pattern, but all has easily gas leakage, dress folding and the inconvenient problem of inflation.
Summary of the invention
The invention provides a kind of valve inside pile, have dress, roll over and inflate all characteristics very easily, and use the back to be difficult for leaking gas.
The technical solution adopted in the present invention is: the air inlet stake on the tire is straight mouthful formula, the bottom is provided with a circle retaining bank, on the circle retaining bank axostylus axostyle is housed, be with spring outward, softer piston is equipped with in the upper end of axostylus axostyle, and the gas stake can be connected one with tire, be with the inflation nut outward, its top is an inflation inlet, is provided with a packing ring with the place of screwing, gas stake top in the inflation nut, is used for blocking not outwards gas leakage of inflation inlet with the piston driving fit of axostylus axostyle upper end.
The invention has the beneficial effects as follows: the air inlet stake be uncovered and with the inflation nut be that split screws, piston, the spring dress folding of being convenient to inner core is changed, the gas that the driving fit of its piston and packing ring can be blocked after the pressurization fully outwards leaks gas.
Description of drawings
Accompanying drawing is a structure cut-away view of the present invention.
Embodiment
Among the figure: be connected the air inlet stake 1 of one with tire 9, its lower end circle retaining bank 2, in the axostylus axostyle 3 of packing into, be inserted in spring 4 outward, piston 5 is withstood on top, inflation nut 7 screws in gas stakes 1, in the packing ring 6 and piston 5 driving fits of packing into, the upper end inflation inlet 8 of inflation nut 7.
During use, gas-filled pump revolves and blocks inflation inlet 8, inwardly inflation, air pressure pours the piston 5 that backs down with packing ring 6 driving fits, superheated steam enters tire 9, charge gas after, the spring 4 of axostylus axostyle 3 overcoats upspring top piston 5 again with the stifled firm tire 9 of packing ring driving fit in superheated steam.
Claims (1)
1, a kind of valve inside pile, it is characterized in that: circle retaining bank (2) can be arranged with air inlet stake (1) bottom that tire connects as one, in the axostylus axostyle (3) of outer casing spring (4) is housed, there is piston (5) on the top of axostylus axostyle (3), the outer inflation nut (7) that is rotary with of air inlet stake (4), its top is inflation inlet (8), in packing ring (6) is housed.
