Description

Four pipes, three piston gas cylinder aerogenesis apparatus

Technical field

The utility model relates to a kind of inflator device, and particularly a kind of hand is played the improvement with the Pedal inflator aerogenesis apparatus.

Background technique

For the ease of bicycle, motorcycle, the tyre inflation of vehicles such as tricycle, Patent Office of the People's Republic of China discloses a kind of novel pump on April 22nd, 1998, the patent No. is 96240985.5, its structure is that the inner barrel that an end has outer piston is set in a big slightly outer cylinder body, a piston is arranged in the inner barrel, air-guide standpipe passes the intercommunicating pore on the outer piston, one end is fixed on the upper base of outer cylinder body, the other end is connected with intercommunicating pore on the inner carrier, air-guide standpipe has pore near an end of upper base, the upper base of outer cylinder body is provided with one-way valve, and the other end of inner barrel sets out valve.When being characterized in utilizing the pump of this structure, inside and outside cylindrical shell is inflated through outlet nozzle after lower chambers is converged by inside and outside piston while aerogenesis, and gas production is big, efficient is high; Its deficiency is: the one, and the pressurized gas of the generation of last inner chamber enters lower inner cavity by air-guide standpipe, increases the resistance to motion of inner carrier; The 3rd, as long as there is a piston to leak air, just can't use; The 3rd, there is not air-storage chamber, feel is heavier relatively.

Summary of the invention

For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provide a kind of rational in infrastructure, feel is light, gas production is big, three four pipes, three piston gas cylinder aerogenesis apparatus that piston is inflated simultaneously.The technological scheme that its technical problem that solves the utility model adopts comprises outer cylinder body, inner barrel, outer piston, connecting base, outer one-way valve, the bottom of inner barrel is fixed on the connecting base, outer piston is fixed on the inner barrel top, outer cylinder body is enclosed within on the inner barrel, outer one-way valve is arranged on the outer piston, its import communicates with upper chamber, be provided with two piston barrels that are connected as a single entity in the described inner barrel, being respectively equipped with piston in two piston barrels reaches and the fixing piston rod of piston, piston rod passes the top that outer piston is fixed on outer cylinder body, be respectively equipped with one-way valve on the connecting base corresponding with two piston barrels, the import of one-way valve communicates with lower chambers, outlet links to each other with air flue on the connecting base, cavity between inner barrel and two piston barrels constitutes the air storage interlayer, the outlet of outer one-way valve links to each other with the air storage interlayer, and the air storage interlayer is communicated with air flue on the connecting base.

In order to guarantee motion sealing between outer piston and the piston rod, prevent upper chamber's gas leakage, described outer piston is provided with the seal ring that cooperates with piston rod.

For the ease of air inlet, the joint of described inner barrel and piston barrel is provided with inlet hole.

Cooperate for the ease of inside and outside cylindrical shell, the bottom of described outer cylinder body is fixed with bottom.

After adopting said structure, outer cylinder body and outer piston combination and two piston barrels and two inner carriers make up three inflators that work alone respectively, inflate respectively by outer one-way valve and two one-way valves, the gas that is produced can be stored in the air storage interlayer of double-layer barrel, the air storage interlayer plays the effect of high pressure gas bag, closing three is one, has the characteristic of triple gas cylinders, and one of them blow-by of piston can not have influence on two pistons works in addition; Have rational in infrastructure, advantages such as feel is light, gas production is big, triple inflation, long service life.
