The inflator comprises a first joint, a first air cylinder, a piston rod, a second joint and a second air cylinder, wherein the two joints can bear different objectives to be inflated respectively; a first chamber is formed between the first air cylinder and the piston rod; a second chamber is formed in the second air cylinder; the two chambers provide unequal air output for the two joints; and the two air cylinders move oppositely in a staggered mode.
Description
Technical field
The invention belongs to mechanical field, particularly a kind of pump that is applicable to different pressures and tolerance.
Background technique
Traditional pump is used in the inflation of bicycle tyre, because the tire needs is large-minded, therefore traditional pump is designing by the filling atm number.Bicycle had had the design of shock-damper for bicycle in order to pursue the comfort level that drives afterwards, and the population that drives at present bicycle is more and more, and the bicycle that therefore is provided with shock absorber is more and more common.The shock absorber of bicycle often is located at the front fork of bicycle, or other position of cycle frame, because shock absorber needs the inflation of high pressure and little tolerance, therefore traditional pump also can't be used in the filling shock absorber, because traditional pump can only beat low pressure and inflate quantity is excessive, the uncontrollable inflate quantity of the order person of inflating, and inapplicable problem is arranged.
With reference to No. the 5676529th, U.S. Patent number " COMPACT MANUAL AIR PUMP HAVING SELECTABLE HIGH VOLUME AND HIGH PRESSURE MODES ", it provides a kind of pump that can be applicable to the various inlet amount.This pump includes joint, outer tube, middle pipe, inner tube and cover piece, joint is arranged in an end of middle pipe, the sheathed middle pipe of outer tube and can be relatively in the pipe transverse shifting, be installed with inner tube in outer tube, and the end spiral shell of outer tube is provided with cover piece, and cover piece can selectivity sealing pump end.The operator is by gripping outer tube, make outer tube relative in manage to move and inflate operation.The operator screws tight cover piece, makes cover piece sealing outer tube end, and when operation was inflated in order, gas can enter middle pipe and joint via inner tube fully, and gas can not poured out from cover piece.At this moment, pump can the filling atm number, and is applicable to the object to be inflatable of low pressure.Operator's spiral shell pine cover piece makes cover piece and outer tube end form spacing, and when operation was inflated in order, portion gas can pour out via spacing, makes the little tolerance of pump filling, and is applicable to the object to be inflatable of high pressure.
In realizing process of the present invention, the inventor finds that there is following shortcoming at least in above-mentioned patent:
In outer tube whether the pump that above-mentioned patent provides utilizes the cover piece screw lock, reach sealing or open outer tube end, and further selectivity allows gas whether enter inner tube and middle pipe totally.This cover piece screw lock is in the design of outer tube, need to there be the existence of cover piece can reach the effect of sealing, and cover piece and outer tube end need to be formed with screw-thread fit, and this design that needs to increase cover piece and additional processing cover piece and outer tube end thread can increase processing cost;
in addition, the pump that prior art provides allows the person of inflating utilize voluntarily the mode of screw lock whether to control cover piece sealing outer tube end, when the person of inflating wants to inflate operation, the person of inflating must judge whether to screw tight or spiral shell pine cover piece voluntarily, when the person of inflating has forgotten to switch and when directly inflating operation, might use incorrect inflate quantity to inflate, just find mistake after the person's of inflating possible operation a period of time, the person of inflating need to adjust cover piece again can carry out the correct operation of inflating, moreover the pump that prior art provides also can't be used in shock absorber.
The pump that needs spiral shell hub cap spare that prior art provides, allow inflated operation many one program, when the person of inflating carries out bicycle race, such pump design also can't obtain favor, since the pressure that the person of inflating is free, and this pump that also needs to adjust the switching inflate quantity needs to improve really.
And the pump with switch that prior art provides is comparatively complicated by the internal structure of pump, when making machine shaping, exists the problem of cumulative limit, and further allows the yield of producing reduce, and can increase the expense of die sinking.And this design that needs switch has more increased the difficulty of operation, the person of inflating and left-hand seat immediately.
Summary of the invention
