Abstract

The utility model relates to a self-inflation apparatus for a bicycle, which is a mechanism used for the self-inflation of rubber wheel vehicles such as bicycles, motorcycles, motor cars, etc., during the running process. The utility model adopts an on-off pin 23, an eccentric groove plate 15 and a strip-shaped guiding groove 32 on an air cylinder 12 to replace the swivel motion of a wheel 33 with the reciprocating rectilinear motion of a shifting pin 3, and the inflation is realized by that the shifting pin 3 drives the piston 2 and the bowl-shaped sealing ring 29. The utility model can inflate the wheels of a bicycle when the bicycle runs, and has the advantages of trouble saving, reliable operation, no burst caused by excessive pressure, fast inflation speed, etc.

Description

Self-inflation apparatus for bicycle

The utility model is a kind of self-inflating machine that is used for bicycle (rubber-tired carts such as automobile, motor bike).

As everyone knows, the bicycle inflation is all carried out with inflator or air compressor air accumulator under dead ship condition, and can't carry out in operational process.Thereby to often worry about effort for this reason, especially meet and fall just trouble more of gas in the way.

The purpose of this utility model is to overcome the bicycle gas filed disadvantage of must stopping, and makes it just can realize self-inflating easily in operational process.

Scheme of the present utility model is to adopt on-of pin and eccentric frid to convert the gyroscopic movement of wheel the linear reciprocating motion of finger to, and realize by its finger driving double acting or single-lift micro pump.

Illustrated below in conjunction with drawings and Examples:

Fig. 1 is bicycle self-inflating machine scheme drawing (micro pump is a double acting, installs in wheel secant direction);

Fig. 2 is the C-C cut-away view of Fig. 1;

1 is housing screw; 2 is piston; 3 is finger; 4 is micro pump; 5 is attaching parts; 6 is wheel hub; 7 is car bumper; 8 is spoke; 9 is airtight core; 10 is safety valve; 11 is tracheae; 12 is cylinder; 13 is the garden spider disc; 14 is eccentric slot; 15 is eccentric frid; 16 is axle sleeve; 17 is lining; 18 is baffle plate; 19 is interior bearing cap shim; 20 is axletree; 21 is nut; 22 is the outer pad of adjusting; 23 is on-of pin; 24 is spring; 25 is shrinkage pool; 26 are the cover that rolls; 27 is vehicle frame; 28 is attaching parts; 29 is bowl ring; 30 is spoke; 31 is air cylinder cover; 32 are the bar shaped guide groove; 33 is wheel.

Eccentric frid (15) is a garden plate, has an endoporus and axle sleeve (16) to be bearing fit in non-central place; Ring eccentric groove (14) is arranged, as the tracks of the finger (3) and the cover (26) that rolls in the periphery of right flank; The middle part is provided with shrinkage pool (25), in order to socket joint on-of pin (23).

Finger (3) is a little axle, and right-hand member is excessive with hole, horizontal garden on the piston (2) and cooperates, and left end overlaps (26) and is running-fit with rolling.

Little shape inflator (4) is made up of piston (2), bowl ring (29), cylinder (12), airtight core (9), tracheae (11), divides double acting and single-lift.Respectively there are a bowl ring (29) and an airtight core (9) in the double acting two ends, and inflation all can be realized in two ends; Single-lift, only at one end be provided with a bowl ring (29) and an airtight core (9), have only an end to realize inflation.

Little shape inflator (4) can be fixed on spoke (30) and the wheel hub (6) by attaching parts (28), (5) along the radial direction or the secant direction dual mode of wheel.

Piston (2) is exactly a minor axis.For double acting, central authorities are provided with hole, horizontal garden, and with socket joint finger (3), each fixes a bowl ring (29) by housing screw (1) at two ends; For single-lift, the hole, horizontal garden of socket joint finger (3) is positioned at an end, and the other end is fixed a bowl ring (29) by housing screw (1).

Cylinder (12) is an inner wall smooth garden tube, and it is interior in order to piston (2) and bowl ring (29) to be installed.For single-lift, end sealing, an end is uncovered.Closed end communicates with valve inside (9), has axial bar shaped guide groove (32) on the sidewall of opening end, does reciprocating linear motion within it for finger (3); For double acting, an end seals, and communicates with airtight core (9), and the other end and air cylinder cover (31) are tightly connected, and axially bar shaped guide groove (32) is opened in central part.

On-of pin (23) is a "T"-shaped minor axis, is placed in the through hole on the vehicle frame (27), and left end is enclosed within the spring (24).

When bicycle in operational process, when needing inflation, can pull the leverage (not shown), compression spring (24), on-of pin (23) is inserted in the shrinkage pool (25) of eccentric frid (15), and eccentric frid (15) is braked, and is relative static with vehicle frame (27).Thereby just under the qualification of the axial bar shaped guide groove (32) on eccentric frid (15) and the cylinder (12), it is reciprocating in cylinder (12) to drive piston (2) and bowl ring (29) for finger (3).When piston (2) when deviating from the motion of certain end valve inside (9) direction, the B space of this end of cylinder (12) forms vacuum, atmosphere just forces the elasticity lip of bowl ring (29) to shrink, and and form small annular space between cylinder (12) inwall, and enter this B space thus; When treating piston (2) counter motion, this compressed air in B space just forces the elasticity lip and cylinder (12) the inwall driving fit of bowl ring (29).Continuation with its motion, the air pressure in this B space raises gradually, when treating that its pressure reaches a certain numerical value, just backing down this airtight core (9) enters in tracheae (11) and the tire, and so forth endlessly, air is pressed into tracheae (11) and tire one after another, and to satisfaction or setting pressure, safety valve (10) begins the pressure release take-off until Tyre inflating.At this moment, pull leverage, the shrinkage pool (25) that makes on-of pin (23) break away from eccentric frid (15), eccentric frid (15) just rotate with wheel (33), and piston (2) stops crank motion, and charge operation promptly stops ending.

The utility model has the advantages that bicycle is just inflatable in operational process.And use reliable; Life-span is long; Easy to operate, laborsaving; Can superpressure not blow out; Aeration speed is fast.Be applicable to the bicycle of various models.

Using bicycle for various, desire adopts the utility model, as long as on axletree (20), install the axle sleeve (16) that an endoporus with eccentric frid (15) is the bearing fit state, again thereon, and with attaching parts (28), (5) spoke (30) or the wheel hub (6) that micro pump (4) is fixed on wheel (33) upward got final product eccentric frid (15) dress.

For cycle manufacturer, desire adopts the utility model, can earlier former spoke (8) be strengthened, change system into garden spider disc (13), and go up corresponding to the position of the axial bar shaped guide groove of cylinder (12) at its garden spider disc (13) and to leave bar-shaped trough in parallel, back and forth free for finger (3).Simultaneously spoke (30) is shortened, is installed on the edge of garden spider disc (13).Adopt as mentioned above with bicycle adopt of the present utility model processing method handled get final product thereafter.
