Abstract

The utility model relates to a portable typed hand inflating-pump, comprising a casing and a rubber mouth. The casing is presented in a U-shape. The rubber mouth is fixedly arranged on the side which is far away from the semicircle. A disc, a driving gear, a driven gear, an active bar and a piston are arranged inside the side of the semicircle of the casing. The driving gear and the driven gear are connected with each other in gear teeth connection. The axis of the driving gear is connected with a handle. The handle is extended out of the casing. The axis of the driven gear and the core of the disc is connected fixedly with each other. One end of the active bar is fixedly arranged on the lateral side of the disc. The other end of the active bar is fixedly connected with the piston. The lateral surface with smoothness and air-tightness of the disc is closely contacted with the inner wall of the casing. The cylinder par is the same as the prior inflating-pump. When using, the handle is rotated to provide driving force, and the rotation of the piston is driven by the gear, and then the pumping operation can be accomplished effectively and portably. The portable typed hand inflating-pump has the advantages of simple structure, convenient operation, reasonable conformation and so on. The pumping operation can be accomplished by using the sensing effect of the gear, the time and labor can be saved.

Description

Portable hand pump

Technical field

The utility model relates to a kind of daily necessities, especially a kind of portable hand pump.

Existing and the pump that once had of technical background all needs bigger strength when giving the inflation of tire of bicycle, it is bigger to consume physical efficiency, general child and womans, because strength is less, and the work that is difficult to inflate.

Summary of the invention

The purpose of this utility model has overcome above-mentioned said deficiency, and a kind of portable hand pump is provided, and is used to solve require great effort when the inflating problem of gas of existing pump.

For achieving the above object, the portable hand pump of the utility model comprises housing and rubber mouth, and housing is a U-shaped, away from the affixed rubber mouth of a semicircular side; Be provided with disk, driving gear, driven gear, motion bar and piston in the semicircular side inside of housing; Driving gear is connected with the driven gear gear tooth, and the driving gear axle center is connected with handle, and handle stretches out outside the housing; The core of driven gear axle center and disk is fixedly connected; At an end of the affixed motion bar in the outside of disk, and the affixed piston of the other end of motion bar, its side surface closely contacts in inner walls, and tool is smooth and tightness; Cylinder portion is identical with existing pump device.

After adopting said structure, be driving force,, finish the work of inflating by the gear driven piston rotation with the handle rotation.

The utility model has the advantages that: simple in structure, easy to use, structure has rationally utilized the sensing effect of gear, and the work that can will inflate is finished time saving and energy savingly.

Description of drawings

Fig. 1 is the overall structure schematic representation of the portable hand pump of the utility model.

Embodiment

As shown in Figure 1, the portable hand pump of the utility model comprises housing 1 and rubber mouth 2, and housing 1 is a U-shaped, away from the affixed rubber mouth 2 of a semicircular side; Be provided with disk 3, driving gear 4, driven gear 5, motion bar 6 and piston 7 in housing 1 a semicircular side inside; Driving gear 4 is connected with driven gear 5 gear tooths, and driving gear 4 axle center are connected with handle 8, and handle 8 stretches out outside the housing 1; The core of driven gear 5 axle center and disk 3 is fixedly connected; At an end of the affixed motion bar 6 in the outside of disk 3, and the affixed piston 7 of the other end of motion bar 6, its side surface closely contacts in housing 1 inwall, and tool is smooth and tightness; Cylinder portion is identical with existing pump device.During use, earlier rubber mouth 2 is socketed on the valve, the rocking-turn handle 8 then, and driving gear 4 begins to rotate, and drive driven gear 5 and rotate, and disk 3 also begins to rotate, motion bar 6 setting in motions, piston 7 also moves up and down, and finishes the function of inflating.
