Abstract
The utility model relates to an inflating pump for a bicycle, which can be arranged between a castor and a rim to realize the inflation of the bicycle automatically in a traveling process. A cam is arranged on a mandrel in the castor of the bicycle, a plunger in a cylinder is pushed to be reciprocated, so that tyres can be inflated via an air outlet valve and a flexible pipe. The inflating pump has the advantages of simple and compact structure, fast inflation, low cost, and convenient assembly and disassembly. The utility model can realize automatic inflation by slightly refitting the castor of an existing bicycle.
Description
The utility model relates to a kind of inflation pump of bicycle, and it can be inflated to bicycle in advancing automatically.
Existing Floor Pump or inflation pump all need stop and inflate, and waste time and energy, and carry inconvenience.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of automatic pump-up device that is contained between bicycle castor and the rim is provided.
A kind of bicycle inflation pump comprises inlet, outlet, safety valve, flexible pipe and geometrical clamp, and the end that the axle in the castor is provided with cam, piston contacts with cam face under the effect of elastic component, and the column type cylinder links to each other with castor.Rotate around the cam axle by castor, drive piston and move back and forth, realize inflating automatically.
This inflation pump is simple in structure, small and exquisite, and mounting or dismounting are convenient, inflates soon, and cost is low.The castor of existing bicycle reequiped to be implemented in a little inflate automatically in advancing.This pump volume is little, and is easy to use, with after can pull down and carry with car.
Accompanying drawing is the structural representation of this inflation pump mode of operation.
Castor 5 internal diameters of ordinary bicycle are strengthened, and two side shaft holders 4 make small one and large one into, so that on axle 1, assemble cam 6, and the bullet bowl 3 of packing into then, steel ball 2 is promptly finished the repacking to castor.In the time of need inflating, cylinder 11 and castor 5 usefulness jam nuts 9 are tightened, and made the roller 8 of ladder column type piston 12 front ends pass aperture on the castor 5, with cam 6 surperficial contacts; The other end is communicated with the valve of tire 23 by flexible pipe 22, geometrical clamp 21.
The cross section of cylinder 11 can be stepped appearance (or column type), and big end is cam end, and small end communicates with the flexible pipe 22 of giving vent to anger.One side of cylinder body is provided with by steel ball 14, breather cheek valve 13 and steel ball 20 safety valves 18 that spring 15 is formed, and can adjust pressure (also can not establish full peace valve) through setting nut 19.Cylinder head and flexible pipe junction 17 are provided with unidirectional air outlet valve 16.Compression spring 10 is placed in internal diameter sudden change place of cylinder middle part, resets in order to piston 12.The roller 8 of piston nose is fixing by roller pin 7.The surface of other end piston is provided with oil groove.
