Abstract

The utility model relates to a bicycle pump. The sprocket wheel of a bicycle is connected with the flywheel of the input shaft of a gearbox by chain transmission. The output shaft of the gearbox is the mandrel of a pump, or is connected with a piston pump through a crank wheel. The exit end of the pump is connected with a supercharging jar. The flywheel of the input shaft of the gearbox is driven to rotate by a chain plate which is driven to rotate by stepping pedals. When speeded up, the rotation speed is output from the output shaft to drive the pump to work. The bicycle and the pump are matched to be used, so the utility model makes no use of electricity and other fuels, has the advantages of suitable power capacity, simple structure, light weight, convenient and flexible installation, move and use, is suitable for fields which are far away from residential areas and unfixed places which do not have sufficient water source and have to move frequently.

Description

Pump of bicycle

The utility model provides a kind of and steps on people's power-driven pump that bicycle pedal is used as power to pedal.

At present, its power of Chang Yong water pump has electricity, motor, artificial etc.For there is not place fixing and that do not have sufficient water source, need frequently move away from village, non-transformer, wilderness,, bring many inconvenience to the user by electricity or engine-driven water pump.Manual pumps such as various plunger pump, though easy to use, the continuous rating deficiency, labor intensity is big, and using effect is not good.

The purpose of this utility model be to overcome the deficiencies in the prior art and a kind of installation be provided, move, flexible and convenient to use, suitable power, high working efficiency, manual driven Pump of bicycle applied widely.

Design of the present utility model is: to step on bicycle foot-operated by stepping on, and the flywheel that chain drives on the gearbox input shaft that moves through of chain drum is rotated, and after the gearbox speedup, output shaft drives pump operation.The technical solution of the utility model is: the sprocket wheel of bicycle and the flywheel chain of gearbox input shaft are in transmission connection, output shaft of gear-box is the water pump axle, or output shaft of gear-box is connected with reciprocating pump by crankwheel, and water pump, reciprocating pump outlet end can be connected with booster jar, to improve lift.

The method of implementing is: between bicycle axis and front-wheel, one gearbox is set, one bicycle front-wheel fixed base and middle shaft fixing support are arranged on the gearbox, in order to bicycle axis and gearbox are located, in gearbox input shaft outer end one flywheel is installed, is made flywheel and chain drum on same straight line, drive and remove the bicycle chain baffle plate, chain is turned linked on the flywheel of gearbox input outer end, make bicycle chain drum and output shaft form transmission joint by flywheel.Gearbox one side has water pump, and the output shaft of gearbox is the water pump axle, or crank disc that plays wheel action of output shaft of gear-box outer end connection, and the piston rod that drives reciprocating pump by connecting rod is reciprocating, with the driven plunger pump.Water pump, reciprocating pump outlet end can be connected with booster jar, to improve lift.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial enlarged drawing of Fig. 1;

Fig. 3 is the utility model embodiment 2 a structural representation;

Fig. 4 is the utility model embodiment 3 a structural representation.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Among Fig. 1, outside the speedup casing 15 front-wheel fixed base 2 and middle shaft fixing support 16 are arranged,, speedup casing and bicycle middle shaft seat are fixed in order to stationary bicycle.Blockchain wheel 3 is connected with flywheel 5 chain-driven of gearbox input shaft 6 outer ends, and input shaft 6 is connected with output shaft 8 gear transmissions through axis 7, and the axle of water pump 9 is made in output shaft 8 outer ends, and rotating speed increases progressively through three grades, exports driving water pumps 9 from output shaft 8 and works and move.Pump outlet tube 11 connects cylindrical booster jar 12 to improve lift.10 is pump intake.

Among Fig. 2, flywheel 5 is installed on input shaft 6 outer ends of speedup box 15, is in transmission connection by the chain drum on chain and the bicycle middle shaft.Axle shaft 8 is gone into axle 6 gear transmissions by axis 7 and axle and is connected, and forms system-wide three grades of speedups, and the impeller 13 of water pump 9 is installed on the outer end of output shaft 8.Pedal the pedal per second once, the rotating speed of water pump promptly reaches per minute 1600 to be changeed, and produces enough big centrifugal force and realizes drawing water, and pump discharge 11 is connected with cylindrical booster jar 12, reaches the purpose that improves lift.14 is seal ring.The about 6t/h of this discharge of pump, lift 3～10m inhales journey 1～2m.

Among Fig. 3,1 is the bicycle front-wheel, and 2 is the front-wheel fixed base, 3 bicycle chainwheels, 4 pedals, 5 flywheels, 6 input shafts, 8 output shafts, 9 water pumps, 10 water intakes, 11 exit of pump, 12 booster jars.

Chain drum 3 is connected with flywheel 5 chain-driven, big belt wheel on the input shaft 6 is in transmission connection by the small pulley on angle band and the output shaft 8, big belt wheel on the output shaft 8 is in transmission connection by angle band and the small pulley that is installed on water pump axle outer end, forms system-wide three grades of speedups.Pedal the pedal per second once, making pump rotary speed reach per minute 1600 changes, and realizes drawing water.

Among Fig. 4,1 is the bicycle front-wheel, and 2 is the front-wheel fixed base, and 3 is bicycle chainwheel, 4 pedals, 5 flywheels, 6 input shafts, 8 output shafts, the outer end of output shaft 8 connects the crank disc 17 of the wheel effect of taking off, the piston rod 19 that drives bidirectional piston pump 21 by connecting rod 18 is reciprocating, and the to-and-fro motion of crankwheel connecting rod 18 promptly drives the bidirectional piston pump and makes two-way pump water, and its pump water yield is greater than centrifugal pump.Under the more high-lift situation of need, the piston delivery side of pump can connect a booster jar to improve lift.

The utility model has the advantage of, bicycle and water pump are used that not electricity consumption and other fuel are applicable in place fixing away from wilderness, the nothing in residential area and that do not have sufficient water source, need frequently move. The utility model is simple in structure, in light weight, install, move and easy to use and flexible, and applied widely, suitable power can reduce labour intensity, increases work efficiency, and is applicable to farmland covered by contract, the orchard in rural area, the pumping irrigation in vegetable plot.
