Abstract
A high pressure inflator comprises a handle, a piston pumping rod, a pressing buffer spring, a clamping plate, a cup piston and an inflator which are sequentially connected forming an upper inflating mechanism. The lower end of the inflator is provided with a two-stage pressure boost cartridge which is connected with a first stage and a second stage pressure boost cartridge and is connected with an one-way valve, the pressure boost cartridge is connected with the chassis of the inflator. The chassis of the inflator on one side of the pressure boost cartridge is provided with a connecting spout, a rubber pipe, an air cock clamp and a pedal rib. In the process of inflating, compressed air is inflated into the pressure boost cartridge through the one-way valve without reversed flow in the upper inflating mechanism, and as the air quantity is increased, the air pressure in the pressure boost cartridge is also increased gradually. The pressure spouted out of the air cock in the process of inflating is increased, and the resistant force and the downward pressure of the human body are decreased. The utility model is applicable to the inflation of a bicycle, a motorcycle, a tricycle, a wheel barrow and other pneumatic tires.
Description
Affiliated technical field
The utility model is a kind of high pressure pump that charging air inlet penetrates pressure that improves, and is used for the inflation of bicycle, motorcycle, tricycle, wheelbarrow and other small-sized carcass of being bullied.
Background technique
General pump is because the pressure of ejaculation valve is little, and when tyre inflation tolerance increased gradually, its resistance and the strength that presses down that needs of inflating also increased thereupon, and this just causes painstaking difficulty to the little person of power.
Summary of the invention
Downforce when inflating in order to improve the pressure that the pump valve penetrates, to alleviate human body, the utility model provides a kind of high pressure pump, and it can improve the pressure that valve penetrates when inflating.
The technical solution of the utility model is: the handle nut of pump handle central authorities is connected with piston inflating rod upper end, last pressure damping spring, being connected with wear-resistant sleeve increases the mouthpiece cover of working life and coaxality, on carry damping spring, set screw nut, pressing plate, leather bucket, plain cushion, gland nut, order is from the lower end attaching of piston inflating rod, pack in the upper end endoporus of one end of piston inflating rod leather cup by air-inflating tube, air-inflating tube upper end spins with mouthpiece cover, constitutes top and inflates mechanism.
The air-inflating tube lower end spout part and the top attaching of barrel-shaped tube of mechanism of inflating is good by one-way valve base, sealed rubber ring, valve seat, sphere open and close valve, switching valve body, the Returnning spring of an outer garden Zhou Yousi groove exhaust, the first order pressurization cylinder of the pressurization cylinder of the one-way valve that air valve connecting sleeve, the air inlet of order attaching formation do not reflux has the upper end portion on top to connect, lower end nozzle portion has the upper end portion on top to be connected with second level pressurization cylinder, and lower end nozzle portion and inflator base connect and compose bottom pressurized gas booster body.
By connection nipple, tighten up cover and be connected with rubber pipe one end, the rubber pipe the other end presss from both sides and is connected with tightening up cover, valve, the connection nipple lower end is put into and is sealed plain cushion and be connected, constitute gas transmission with the upper end of inflator base pore and connect the mouth pipe.The foot-operated muscle of U-shaped has been installed on the inflator base of connection nipple one side, and foot-operated muscle can rotate up and down.
By piston inflating rod, damping spring, mouthpiece cover, the air-inflating tube that leather bucket is housed on top, with first order pressurization cylinder, the second level pressurization cylinder of bottom and be installed in one-way valve in the pressurization cylinder, inflator base all from top to bottom attaching on an axis.
Top inflates the one-way valve base ventilation holes of air-flow in pressurization cylinder that mechanism's injection goes out when inflating, the valve seat pore is washed the sphere open and close valve that closure is sealed open, by the air vent that opens and closes valve body, the connecting sleeve pore enters in the pressurization cylinder, because one-way valve can only unidirectionally enter air-flow, all pressure effect and the atmospheric pressure after the air inlet owing to Returnning spring do not make the sphere open and close valve under the situation that no suction pressure is washed open when having air pressure in the two-step supercharging tube and air pressure is arranged, keep being close to closure with the valve seat pore, the gas that enters the two-step supercharging tube can not be refluxed, and the gas in the sealed rubber ring sealing two-step supercharging tube can not reflux through base ventilation holes from the gap of air valve connecting sleeve and one-way valve base.Because the gas that enters in the pressurization cylinder can not reflux, along with the increase of tolerance, the air pressure in the pressurization cylinder also increases step by step, has improved the pressure that penetrates valve, has reduced resistance and downforce when inflating.
The beneficial effects of the utility model are: smoothness simple for structure, the pressure height of ejaculation valve, the dynamics that has reduced resistance when human body is inflated and pressed down.
