Description

The vehicle self-filler

The utility model relates to a kind of self-filler that is fixed on the vehicle.

Bicycle is the topmost vehicle of China town dweller, and on and off duty or student goes to school and be unable to do without it, is a kind of green traffic instrument, for alleviating environmental protection pressure, in many developed countries, is also promoting it as the body-building or the instrument of riding instead of walk.Present bike tyre all adopts inflatable inner tube to be equipped with the antifriction cover tire and forms, and the new inner tube of a tyre is protected the gas time about a week, promptly need often give tonifying Qi for used tire, otherwise can influence the life-span of vehicle corresponding component, and increase resistance.Seen on the market inflatable appliance has artificial Floor Pump and the automatic inflatable appliance of pneumatics pump now, the former has become the apparatus of herbal, every day is by bike the time, all to check the air pressure of tire, on the way poked or leaked gas if run into tire, need to shift car onto maintenance point and handle, both bothered also time-consuming.The material of bicycle charging-self type pump-up device was once disclosed in patent gazette, its main composition is a little inflator, the air extractor duct of inflator docks with the air inlet valve of tire, the piston of inflator joins through connecting rod and gravity pendulum, collect this and pick up power, wheel one circle, gravity pendulum are just finished the stroke that swings, and promote piston and finish air-breathing and process compression exhaust.This apparatus structure is simple, and is easy for installation, only need be fixed on the tire spoke to get final product.Weak point is that the power that picks up of gravity pendulum is limited, the inflator insufficient pressure, and inflation slowly and is not fully filled, and when then wheel travelled in addition, inflatable appliance was also wasted the life-span of consumable accessorys such as piston all the time in work.

The purpose of this utility model is that design is a kind ofly directly picked up wheel power by gear structure, the vehicle self-filler that inflator air pressure is high.

Task of the present utility model is finished like this, the vehicle self-filler that comprises a small-sized inflator, the base that it is characterized in that inflator is fixed on the vehicle wheel wheel, the inflator base is provided with a rotating shaft, one end of rotating shaft is fixed with a flying disc, one end of connecting rod is socketed on the inflator piston, the other end is enclosed within on the protruding axle of flying disc, protruding axle is away from the flying disc axle center, and the other end of rotating shaft is fixed with a big gear wheel, be positioned on the wheel wheel by bearing with its ingear miniature gears, miniature gears has a control panel, and the control latch is fixed on the vehicle frame.When vehicle in motion, its gas filled device integral body is being followed wheel and is being rolled together, each parts does not all do relative motion, and can not produce unnecessary abrasion yet; When needing inflation, will control latch and pin control panel, and make miniature gears and vehicle frame form relative motionless one, the wheel that rolls this moment drives inflator and rotates, force big gear wheel around pinion rotation, and drive piston motion, finish air-breathing and the compression exhaust action by connecting rod.

The utility model adopts gear structure to pick up power, have and transmit reliably, and moment is big, and the compressed gas air pressure height that produces in the inflator improves gas filed efficient and fullness degree, satisfies the pressure requirement of tire substantially; And be provided with the control latch, prolong the service life of gas filled device greatly.

Below in conjunction with concrete legend the utility model is described further:

Fig. 1 is the utility model generalized section

Fig. 2 is the utility model running condition figure

With reference to Fig. 1, the main body of vehicle self-filler comprises a small-sized inflator 1, the base 11 that it is characterized in that inflator is fixed on the vehicle wheel wheel 2, inflator base 11 is provided with a rotating shaft 3, one end of rotating shaft 3 is fixed with a flying disc 31, one end of connecting rod 4 is socketed on the inflator piston 12, the other end is enclosed within on the protruding axle 33 of flying disc 31, and protruding axle 33 is away from the flying disc axle center, and the other end of rotating shaft 3 is fixed with a big gear wheel 32, be positioned on the wheel wheel 2 by bearing with its ingear miniature gears 5, miniature gears 5 has a control panel 51, and control latch 52 is fixed on the vehicle frame, and the diameter of control panel 51 is big than miniature gears 5, increase the arm of force, the braking force when reducing control.In order to alleviate the influence of when inflation to driving vehicle, inflator 1 is a gas cylinder, be provided with admission port 15 in the piston chamber on the gas cylinder 1, deposit 13 of air chambers with high pressure and be provided with pressure valve 17, be provided with a connector that docks with tyre valve core 14 at the air extractor duct place of gas cylinder 1, connector 14 is provided with limiting valve 16, in order to avoid the too high inner tube of a tyre that makes of gas cylinder inflation pressure breaks.What be communicated with the inflator air extractor duct in the connector 14 is a check valve 18, check valve 18 is existing general-duty inner tube valve cores among the figure, also promptly have in the side on the spool of air extractor duct and form by a rubber sleeve, the sidewall of connector 14 is provided with a limiting valve 16, and limiting valve is provided with an adjusting pressuring knob 19, can adjust the inflation pressure of inflator according to the withstand voltage parameter of the different inner tubes of a tyre.

The above-mentioned flying disc of mentioning 31 that is fixed in the rotating shaft can be a crank, can reach the purpose of transferring power equally.

With reference to Fig. 2, for the utility model is installed in scheme drawing on the bicycle, connector 14 on the stingy tube of the gas filled device air extractor duct docks with the valve 61 of tire 6, the inflator partial fixing is in the centre of car wheel both sides spoke during installation, intermeshing big miniature gears is installed in the spoke outside, control latch 52 is regularly on the vehicle frame 7, and control latch 52 causes operation when being convenient to inflate on the handlebar 8 by tightrope.
