Abstract

The utility model provides an automatic tyre inflating pump mounted on a bicycle, which is provided with a shell with a close over. A reciprocating plunger inflator is arranged in the shell. The utility model has the novel points that the inflator is driven by a driving mechanism composed of a stationary gear which is arranged on a wheel shaft, a drive gear which is engaged with the stationary gear and a drive shaft which is integrally connected with the drive gear, and is sheathed on a crankshaft. The automatic inflation is realized by an inflating control mechanism composed of an air bag and a continuous wane mechanism. The rider does not need to use the present inflator. Even when the tyre is stuck to leak air, the inner air pressure can be temporarily maintained, and the bicycle does not need to be instantly stopped for repairing.

Description

Automatic tyre inflating pump mounted on bicycle

The utility model provides a kind of inflating pump mounted on bicycle pump that is installed on the bicycle quick.

Now bicycle inflate be to use the Floor Pump that separates with bicycle when stopping with manually inflating.After not having Floor Pump or tire to be stabbed at one's side, the cyclist can be absorbed in the border of embarrassment, has to that car is pushed into repair location and handles.

The purpose of this utility model just provides a kind of inflating pump mounted on bicycle pump that is installed on the bicycle quick, makes the cyclist avoid above-mentioned hardship.

For achieving the above object, the utility model design plan is: a kind of bicycle inflating pump mounted on bicycle pump, and it has a housing that has capping that is installed on the wheel Decorative drum; In the housing by an inflation pump of forming by bent axle, connecting rod, plunger, cylinder, air inlet valve and charge valve, special feature of the present utility model it also have one by be installed on fixed gear wheel on the bicycle shaft, and fixed gear wheel ingear transmission gear and one that fuse with transmission gear and be sleeved on driver train and ventilating control mechanism that the transmission shaft on the bent axle is formed.

Make specific description below in conjunction with embodiment of the present utility model and accompanying drawing thereof.

Fig. 1 is the structure cutaway view of present embodiment.

Fig. 2 is the plan structure cutaway view that removes capping among Fig. 1.

Fig. 3 is seesaw among Fig. 2, U type frame, shift fork connection structure schematic detail view.

Fig. 4 is a present embodiment running condition scheme drawing.

As Fig. 1, Fig. 2, bicycle inflating pump mounted on bicycle pump shown in Figure 3, have a housing 19 that has capping 14, housing 19 has one in order to be installed in the erecting frame 30 on the wheel Decorative drum (claiming the axletree skin again).Housing 19 is interior by an inflation pump of being made up of bent axle 18, connecting rod 17, plunger 20, cylinder 22, air inlet valve 21 and charge valve 2.The novel part of present embodiment be also have one by be installed on fixed gear wheel 13 on the bicycle shaft, that fuse and be sleeved on driver train and ventilating control mechanism that the transmission shaft 15 on the bent axle 18 is formed with fixed gear wheel 13 ingear transmission gears 12 and one and transmission gear 12.

The concrete scheme of ventilating control mechanism of present embodiment is to be provided with a plenum chamber 26 that is connected with cylinder 22 through charge valve 2 before cylinder 22.Ventilating control mechanism is continuous seesaw form, by an airbag 23 that is connected with plenum chamber 26; An airbag briquetting 25 that is positioned at airbag 23 tops; One one end has bearing pin 24 to be connected with airbag briquetting 25, and there is the seesaw 5 that a fulcrum is 7 that be connected with a column on bearing pin 6 and the housing 19, the other end is provided with open slot 8 at the middle part; One one end has convex column 9 to stretch in the open slot 8 of seesaw 5, and the other end is the U type frame 10 of two jaws; Front end by two be used to stir the jaw of transmission shaft 15, the rear end of stretching between 10 two jaws of U type frame is made up of the shift fork 11 of a groove 33.Run through two jaws of U type frame 10 and the rear end of shift fork 11 is connected to shift fork 11 and U type frame 10 on the support 16 of housing 19 with a bearing pin 27, in an end of bearing pin 27 spring 32 that U type frame 10 is resetted is housed, other has a pipe link 28 that is with pressure spring 29, the one end inserts the bottom of U type frame 10, its other end stretches in the groove 33 of shift fork 11 rear ends, and with bearing pin 31 its both sides with groove 33 is connected.

Plenum chamber 26 has an air-filled pore 34 to communicate with tracheae 1, and tracheae 1 joins with the tire valve inside.Fig. 4 illustrates the running condition of present embodiment.When bicycle was walked, whole Floor Pump rotated with wheel.Transmission gear 12 rotates around fixed gear wheel 13, does simultaneously to rotate the inflation pump work that makes from the bent axle 18 of transferring by transmission shaft 15 drive inflation pumps.Inflation pump is pressed into tire and airbag 23 simultaneously with gas.When reaching, tyre pressure sets when requiring, airbag 23 swells, jack-up airbag the briquetting 25 and open slot 8 that drives seesaw 5 is depressed the convex column 9 on the U type frame 10 downwards, the bottom of U type frame 10 moves downward, by the effect of pipe link 28, make the rear end perk of shift fork 11, two jaws of the front end of shift fork 11 press transmission shaft 15 downwards, drive transmission gear 12 and break away from fixed gear wheel 13 downwards, this moment, pump stopped to inflate.When tire reduces because of the air pressure that loses heart and during less than the air pressure in the airbag 23, gas in the airbag 23 goes because of draught head can be injected in the tire voluntarily, airbag dwindles because of losing gas for 23 this moments, and this ventilating control mechanism can make and above-mentioned opposite motion, and Floor Pump is returned to the state of inflating again.

Set that air pressure can be by being provided with airbag pressing plate 25 cooresponding positions in the capping 14 one by pressure regulating screw 4 and be pressed in the pressure regulating device that the pressure spring 3 on the airbag briquetting 25 formed and realize.

Bicycle wheels is all loaded onto this charging-self type pump, and the cyclist needn't re-use present Floor Pump.Stabbed gas leakage and also can temporarily be kept the tire internal gas pressure even run into tire, do not needed the repairing of stopping at once.
