Abstract
The utility model relates to an inflating device for a bicycle. The utility model is designed in view of autoinflation and sensitivity indication at night for tire type manpower or electric single bicycle, such as 26, 28 bicycles, mountain bicycles, tricycles, etc. The utility model is mainly composed of a guide baffle plate and a miniature inflating cylinder, wherein, the guide baffle plate is fixed to a shaft. The miniature inflating cylinder is fixed to a hub. A connection handle slides in a guide groove through a slide shaft to drive a pull rod and a piston is driven by the pull rod and move up and down in the inflating cylinder. Thereby, the goal of autoinflation can be achieved. The utility model has the advantages of simple structure, convenient operation, convenient assembly and disassembly and low production cost.
Description
Technical field
The utility model relates to the bigger manpower of tire formulas such as bicycle, motorcycle, tricycle and wheel hub or the self-filler of motor bicycle.
Technical background
China is the big country that has bicycle, tricycle, and at present people inflate to bicycle, still utilizes stand, roadside pump or inflates at the family expenses pump.In addition, when going out, under the situation that generation bike tire becomes flat or blows out, can only push away and look for the people to repair, cause very big difficulty and inconvenience for the person of riding.
The content of model utility
The purpose of this utility model purport provides a kind of bicycle inflator.This device mainly is made up of guiding plate washer, small-sized inflator pump two-part, the guiding plate washer is fixed in the wheel hub in the heart, small-sized inflator pump upper end cap is with tightening up Fixation With Steel Wire at central shaft, lower end cap is fixed on the nut of air inlet nozzle both sides, when connection handle is made circular movement along the guiding groove on the guiding plate washer, drive inflator pump pull bar, piston pump, thereby reach the purpose of automatic inflation.
The purpose of this utility model can realize by following measure:
A kind of bicycle inflator is made up of guiding plate washer, small-sized inflator pump two-part.Guiding plate washer profile such as cam, inner side surface has the guiding groove along cam edge, and a radially big end slot is shallow, on the contrary a radially little end slot is dark.The guiding plate washer is installed on the antero posterior axis, is connected with male thread.Trailing wheel guiding plate washer is between shelf strut and wheel hub; Tighten up with steel wire between the upper end cap of small-sized inflator pump and the axle, sliding axle can slide along guiding groove in sleeve, and sleeve and lock link are for being threaded, and connection handle and pull bar pass inflator upper end cap pull bar drive piston by pin and move up and down in inflator; There is one section groove the sleeve upper end, and manually bolt drive sliding axle slides in the chamber within it.Lower end cap is fixed on the nut of air inlet nozzle both sides, and tightens up with threaded steel wire, and inflator lower end cap center hole is relative with valve.
The utility model compared with prior art, the positive benefit of generation is:
1, when vehicle tyre need be inflated, by manual screw the connection handle rotation is placed guiding groove, pull bar, piston are moved up and down at inflator, realize inflation purpose automatically.After inflation finishes, by manual screw connection handle is rotated, break away from guiding groove, and manual screw is hung on tightens up on the steel wire, solved driving tyre inflation problem easily, really accomplish with riding with filling.
2, trailing wheel installation inflator should be at non-chain end, and then the opposite side of front-wheel installation makes bicycle keep left and right sides balance.Make the person of riding not produce unbalance sensation.
3, guiding plate washer inside and outside side is coated with the safety reflecting material, plays driving and turns to indicative function, can avoid the driving at night owing to turn or traffic accident takes place during jaywalk.
4, the utility model operation, folding dress are conveniently, and be cheap, practical.

Embodiment
In conjunction with the accompanying drawings, the utility model is described in further detail again:
A kind of bicycle inflator is made up of guiding plate washer 1, small-sized inflator pump 12 2 parts.Guiding plate washer 1 profile such as cam, inner side surface has the guiding groove 3 along cam edge, and a radially big end slot is shallow, on the contrary a radially little end slot is dark.Guiding plate washer 1 is installed on the axle 2, and is threaded with axle 2, and trailing wheel guiding plate washer 1 is between shelf strut and wheel hub; The upper end cap 10 of small-sized inflator pump 12 and axle tighten up with steel wire 4 between 2, are added with semicircle rigidity pad on the axle sleeve, in case steel wire 4 damage axle sleeve when tightening up.Sliding axle 6 can slide along guiding groove 3 in sleeve 9, and connection handle 5 passes the upper end cap 10 of inflator 12 with pull bar 11 by pin, and drives piston 13 and move up and down in inflator 12; There is one section groove sleeve 9 upper ends, and manually bolt 7 drive sliding axles 6 slide in the chamber within it.Because the spring-back force of spring, and unlikely connection handle 5 disengagings tighten up steel wire, and lower end cap 16 is fixed on the nut of air inlet nozzle 14 both sides, and the air inlet nozzle upper end is added with seal ring in the time of fixedly, and tightening up inflator 12 with threaded steel wire, inflator lower end cap 16 center holes 15 are relative with valve on the wheel hub.
When wheel need be inflated, by manual screw 7 connection handle 5 is rotated, break away from guiding groove 2, sliding axle 6 slides along guiding groove 3, and drives connection handle 5 and pull bar 4, and piston 13 is moved up and down in inflator 12, gives tyre inflation.After inflation finishes, by manual screw 7 connection handle 5 is rotated, break away from guiding groove 3, and manual screw 7 is hung on tightens up on the steel wire, bicycle continues stroke.
