Abstract
The utility model belongs to an air charging device, specifically a portable air pump. It solves the problem of inconvenient carry caused by the overlong barrel body of the existing air charging pumps. It provides a portable air pump with convenient carry. Two auxiliary barrel bodies with different diameters are orderly sheathed outside the barrel body. The barrel body is connected to a hollow annular piston whose internal diameter is shorter than that of the barrel body. The auxiliary barrel body with a shorter diameter is connected to the other hollow annular piston whose internal diameter is shorter than that of the auxiliary barrel body. Compared with the prior art, the a plurality of sheathed air pumps can be flexible, so the length of the whole air pump is shortened evidently. The utility model can be put in a hollow handle, which makes the carrying convenient.
Description
Technical field
The utility model belongs to a kind of inflator, is specially a kind of portable inflator.
Background technique
In the transport facility, the simple and convenient practicality of bicycle, by ruck is accepted, utilization is extensively.But, the tire of the bicycle flat tire that is easy to leak gas under situation such as freezing, Exposure to Sunlight, valve sealing be bad brings many inconveniences, often can not in time find inflator to give tyre inflation in this case, be merely able to continue to use the bicycle of flat tire, as easy as rolling off a log damage tire.Existing inflation inflator is generally long tubular, cause because of cylindrical shell is long carry very inconvenient.
Summary of the invention
The utility model solves existing inflation inflator and causes the problem of carrying inconvenience because of cylindrical shell is long, and a kind of portable inflator that is convenient for carrying is provided.
The utility model is to adopt following technical proposal to realize, portable inflator, comprise cylindrical shell and the piston that cooperates with cylindrical shell, piston connects piston rod, piston rod flexibly connects handle, cylindrical shell is with the secondary cylindrical shell of two different-diameters outward successively, and cylindrical shell connects inner diameter less than cylinder internal diameter and the hollow ring piston that cooperates with secondary cylinder inboard wall, and secondary cylindrical shell connection inner diameter is less than this pair cylinder internal diameter and another hollow ring piston of cooperating with another secondary cylinder inboard wall.The cylindrical shell socket of a plurality of different-diameters can be shunk in the time of no, has shortened the length of inflator, and hollow ring piston inner diameter is less than the internal diameter of connected cylindrical shell or secondary cylindrical shell, can drive cylindrical shell or secondary cylindrical shell moves together, pressurized air.
The sealing of handle hollow one end, internal diameter is greater than the diameter of the secondary cylindrical shell of diameter maximum.Because the handle internal diameter is big, the inflator that makes inflation finish can be put into it, is convenient for carrying.
The utility model compared with prior art because a plurality of inflator sockets are collapsible, the length of whole inflator obviously shortens, the time spent can not be placed in the handle of hollow, carries easily.

Embodiment
With reference to the accompanying drawings embodiment is further described, present embodiment is to explanation of the present utility model, is not that the utility model is done any restriction.
Portable inflator, comprise cylindrical shell 1 and the piston 8 that cooperates with cylindrical shell 1, piston 8 connects piston rod 4, piston rod 4 flexibly connects handle 5, outer secondary cylindrical shell 2 and the secondary cylindrical shell 3 that is with two different-diameters successively of cylindrical shell 1, cylindrical shell 1 connect inner diameter less than cylindrical shell 1 internal diameter and the hollow ring piston 6 that cooperates with secondary cylindrical shell 2 inwalls, and secondary cylindrical shell 2 connection inner diameters are less than secondary cylindrical shell 2 internal diameters and another hollow ring piston 7 of cooperating with secondary cylindrical shell 3 inwalls, the sealing of handle 5 hollows one end, internal diameter is greater than the diameter of secondary cylindrical shell 3.
During use, take out whole pump from handle 5, handle 5 is connected with piston rod 4, press down piston rod 4, piston rod 4 drives piston 8 and moves downward pressurized air.The hollow ring piston has guaranteed the sealing between the cylindrical shell.Because hollow ring piston 6 inner diameters are less than cylindrical shell 1 internal diameter, hollow ring piston 7 inner diameters are less than cylindrical shell 2 internal diameters, when piston 8 moves to cylindrical shell 1 bottom, piston 8 drives cylindrical shell 1 and moves to secondary cylindrical shell 2 bottoms together, arrive secondary cylindrical shell 2 bottoms and drive secondary cylindrical shell 2 again, move to secondary cylindrical shell 3 bottoms and then finish gas replenishment process one time together to the motion of secondary cylindrical shell 3 bottoms.Pull-up piston rod 4 repeats down press operation.Inflation finishes, because piston rod 4 is to flexibly connect with handle 5, each inflator can be put into handle 5 after shrinking.
Claims (2)
1, a kind of portable inflator, comprise cylindrical shell (1) and the piston (8) that cooperates with cylindrical shell (1), piston (8) connects piston rod (4), piston rod (4) flexibly connects handle (5), it is characterized in that, outer secondary cylindrical shell (2) and the secondary cylindrical shell (3) that is with two different-diameters successively of cylindrical shell (1), cylindrical shell (1) connects inner diameter less than cylindrical shell (1) internal diameter and the hollow ring piston (6) that cooperates with secondary cylindrical shell (2) inwall, and secondary cylindrical shell (2) connection inner diameter is less than secondary cylindrical shell (2) internal diameter and another hollow ring piston (7) of cooperating with secondary cylindrical shell (3) inwall.
2, portable inflator as claimed in claim 1 is characterized in that sealing of handle (5) hollow one end and the internal diameter diameter greater than secondary cylindrical shell (3).
