detailed description

Example

As shown in Figure 1-2, the air pump has a handle 1 on the top of the cylinder 10, a fixed pedal 8 on the bottom of the cylinder 10, the inner cavity of the cylinder 10 is an air chamber, and the upper part of the air chamber is provided with a centrifugal pump. The pendulum flywheel 2 and the centrifugal pendulum flywheel 2 are connected to the inflating piston 4 through the connecting rod 3, and the spring 5 is arranged under the inflating piston 4; the lower part of the cylinder body 10 is provided with an air outlet 6, and the air outlet 6 is connected to the valve core 11 through the rubber tube 7; The cylinder body 10 is provided with a hand handle 9, and the hand handle 9 is connected with the centrifugal pendulum flywheel 2.

There are one or two hand handles.

According to the habits and needs of different people, the portable hand pump is designed as one-handed and two-handed hand-operated modes, and its inflation principle is shown in Figure 3.

One-handed hand mode: when using, hold the handle 1 with one hand, fix the pump on the ground, hold the hand handle 9 with the other hand, rotate the hand handle 9, the hand handle drives the centrifugal pendulum flywheel 2 to rotate, and the centrifugal pendulum flywheel Due to the inertia effect, the connecting rod 3 is driven and the piston 4 of the pump is driven to reciprocate, and the piston does work on the air chamber to squeeze the gas in the air chamber out of the air outlet 6, and the gas is discharged from the air chamber to inflate with the external objects through the rubber tube 7 and the valve core 11.

Two-handed hand-cranking mode: when using, step on the fixed pedal 8 with one foot, fix the pump on the ground, hold the two hand-cranked handles 9 with both hands, rotate the handles and reciprocate the hand-cranked handles, and the hand-cranked handles 9 drive the centrifugal pendulum The flywheel 2 rotates, and the centrifugal pendulum flywheel drives the connecting rod 3 due to inertia and pushes the pump piston 4 to reciprocate. The piston does work on the air chamber and squeezes the gas in the air chamber out of the air outlet 6. The gas is discharged from the air chamber through the rubber tube and the valve core. Externally connected objects are inflated.

When the piston is inflated to work, the spring connected to the piston has a rebound effect at the same time, saving the time of shaking the hand handle.

The above specific descriptions about the utility model are only used to illustrate the utility model and are not limited to the technical solutions described in the embodiments of the utility model. Those of ordinary skill in the art should understand that the utility model can still be modified or equivalently replaced to achieve the same technical effect. As long as it meets the needs of use, it is within the protection scope of the present utility model.
