Abstract
The utility model discloses a high-pressure air pump with two pistons and three tubes. The high-pressure air pump with two pistons and three tubes is characterized in that two air pumps which are respectively formed by an air tube 3 and a piston 4 are arranged in parallel on a base 6; an air storage chamber of each air pump is respectively communicated with an air storage tank 7; a check valve 8 is respectively arranged on a passageway of each air pump; any piston rod 2 can be randomly spun out from a handle 9 as a single-piston air pump. The utility model has the advantages of high inflating speed, high inflating pressure and labor saving; the high-pressure air pump with two pistons and three tubes can inflate with one tube or two tubes. The high-pressure air pump with two pistons and three tubes can be used for inflating small and middle type automobiles, various motorcycles, walking tractors and various non-motor vehicles.
Description
The utility model is a kind of double-piston three pipe high-pressure pumps.
Existing pump generally is single tube or two-tube single piston tube, and its deficiency is that inner gas pressure is low, and aeration speed is slow, can only be the non power driven vehicle service, and can not be vehicle services such as small and medium-sized car, motorcycle, hand tractor.
The purpose of this utility model just provides a kind of inner gas pressure height, and aeration speed is fast, can be the double-piston three pipe high-pressure pumps of vehicle services such as small and medium-sized car, all kinds of motorcycle, hand tractor.
Solution of the present utility model is such: on the basis of former two-tube single piston tube, increase by a cover piston tube again, two piston tubes are installed on the base 6 side by side, the gas storage chamber of each piston tube communicates with gas holder 7 respectively, on passage separately, respectively be provided with a safety check 8, like this, two piston tubes can be divided into two independent inflators uses basically.The piston rod 2 of two piston tubes is connected with handgrip 9, mentions and press 9, two piston tubes of handgrip and work simultaneously, aeration speed is more fast again than single piston tube.And handgrip 9 is a detachable type with being connected of piston rod 2, when filling the large car tire pressure when big, with two-tube wheel is charged to certain air pressure earlier, and when manpower did not prop up, detachably following arbitrary piston rod 2 easily inflated with single piston tube.The volume of gas holder 7 is got optimum value, can solve the phenomenon that manpower does not prop up when filling the large car tire.
The utility model has the advantages that: aeration speed is fast, but single tube is inflated and can two-tubely inflate, and inner gas pressure height, laborsaving can be used for the inflation of small and medium-sized car, all kinds of motorcycle, hand tractor and various non power driven vehicles.
Below by accompanying drawing an embodiment is described
Accompanying drawing 1 is a structural representation
Accompanying drawing 2 is that A is to schematic representation
Accompanying drawing 3 is base vertical views
The utility model is to be made of base 6, piston 4, safety check 8, gas holder 7, piston rod 2, handgrip 9, tracheae 3, the inflator that two tracheaes 3 and piston 4 constitute respectively is installed on the base 6 side by side, the gas storage chamber of each inflator communicates with gas holder 7 by the passage of opening in base 6 respectively, on passage separately, respectively be provided with safety check 8, safety check 8 is arranged on base 6 and gas holder 7 connection places, the gas of gas storage chamber can be flowed in the gas holder 7, and the gas in the gas holder 7 can not pass back in the gas storage chamber.
Two piston rods 2 that are connected with piston 4 are connected with handgrip 9, and piston rod 2 is with being threaded, with nut 1 locking with handgrip 9.When needing single piston tube to use, unclamp the locking nut 1 on arbitrary limit, piston rod 2 is screwed out from handgrip 9, just can be used as single piston tube and use,, seal ring 5 is installed on the piston 4 to increase inflation pressure.
Claims (3)
1, a kind of double-piston three pipe high-pressure pumps, be to constitute by base 6, piston 4, safety check 8, gas holder 7, piston rod 2, handgrip 9, tracheae 3, it is characterized in that two inflators that are made of respectively tracheae 3 and piston 4 are installed on the base 6 side by side, each inflator communicates with gas holder 7, respectively is provided with safety check 8 on passage separately.
2, double-piston three pipe high-pressure pumps according to claim 1 is characterized in that two piston rods 2 that are connected with piston 4 are connected with handgrip 9, can take away arbitrary piston rod 2 from handgrip 9.
3, double-piston three pipe high-pressure pumps according to claim 2 is characterized in that the passage that gas storage chamber communicates with gas holder 7 is out on base 6, and safety check 8 is arranged on base 6 and gas holder 7 joints.
