Abstract

The utility model relates to a combined cylinder type efficient inflator, which is mainly composed of a mother inflator 1, a son inflator 2, an air storing tank 3, a base 4, and an eduction pipe 10. The utility model has the advantages of time saving and labor saving for inflating. The combined cylinder type efficient inflator can be used for inflating for bicycles, and can also be used for inflating tyres of motorcycles, automobiles, etc.

Description

Primary and secondary barrel-type efficient pump

Be used for all kinds of pumps or title manpower inflator at present to inflations such as tires, the shortcoming that exists tolerance and air pressure not to take into account simultaneously during use, promptly under the situation of using identical downforce, though the tolerance that the big pump of each barrel dliameter extrudes is bigger, the air pressure that provides is lower.Otherwise though that the little pump of barrel dliameter presses down the air pressure of acquisition is bigger at every turn, the tolerance that provides is less.When using above-mentioned pump to inflations such as tires, particularly all bigger to the gentle pressure request of tolerance, during as tyre inflation such as motorcycle and automobiles if select the big pump of barrel dliameter, though the initial stage aeration speed is very fast, but finally be difficult to obtain required air pressure, though,, have the shortcoming that wastes time and energy because each tolerance that extrudes is less if select the little pump of barrel dliameter can obtain required air pressure.

The purpose of this utility model provides a kind of time saving and energy saving primary and secondary barrel-type efficient pump that is suitable for inflations such as all kinds of tires of inflating.

Technical solution of the present utility model is: the inflator of two (or more than two) each tool pistons that barrel dliameter is different is serially connected by Non-return air valve, to replace the inflator part of existing monotubular formula pump.Below further narration in an embodiment.

Technique effect of the present utility model is: it is time saving and energy saving to inflate, and is applicable to different all kinds of as tyre inflation such as bicycle, motorcycle and automobiles of the gentle pressure request of tolerance.

Figure of description is the utility model example structure schematic representation.

Embodiment: as shown in the figure, mother-qi tube 1, sub-inflator 2, gas holder 3, being separately fixed on the base 4 of pressure gauge 6 and air valve 9 minutes, the barrel dliameter of mother-qi tube 1 is greater than the barrel dliameter of sub-inflator 2, the suction port of sub-inflator 2 communicates by the air outlet of Non-return air valve 7 with mother-qi tube 1, the suction port of gas holder 3 communicates by the air outlet of Non-return air valve 8 with sub-inflator 2, the air outlet of gas holder 3 communicates with an end of pressure gauge 6 and air valve 9 respectively, the other end of air valve 9 links to each other with an end of steam outlet pipe 10, the other end of steam outlet pipe 10 be connected to successively rotating chew connect 11 and cassette chew and connect 12, cassette is chewed and is connect 12 and can screw on or screw off according to use condition, between mother-qi tube 1 and sub-inflator 2, also be provided with and reinforce cover 5, but also be respectively equipped with the handle chain 13 and the chain hook 14 of siding stopping inflator 2 handle height on the handle of reinforcing cover 5 and sub-inflator 2.

Present embodiment is owing to tool pressure gauge 6 and air valve 9, so it also can be used as the container pressure-bearing and the seepage testing apparatus uses.
