Embodiment
With reference to specific embodiments and the drawings, the utility model is expanded on further.
Hand air pump is occurred in that in the prior art, and catch bar is connected on bent axle by this inflator, by catch bar
Straight reciprocating motion change into the rotation of wheel, so as to design hand air pump.Although hand air pump can be effective
Efficiency is inflated in raising, more meets ergonomics.But hand air pump essence still promotes piston to inflate for catch bar, inflator
Catch bar constantly comes in and goes out piston cylinder in middle cylinder and catch bar equal length, the course of work, can not effectively reduce inflator
Volume operationally.And the contraction in length of inflator can to inflate efficiency reduction；Increase multiple length simultaneously shorter
Inflator can not also effectively reduce inflator volume, and also increase the complexity of device.These pins of the prior art in a word
Improvement to inflator, can not realize that inflator is minimized well, be convenient for carrying or be embedded into miscellaneous equipment.
A kind of hand air pump is provided in the present embodiment, the hand air pump is respectively set at the two ends of a cylinder 1
One piston, two piston relative motions, while the gas inside compression cylinder 1.Effectively increase gas compression efficiency.
Each piston 5 is connected with a catch bar 4 in the present embodiment, and catch bar 4 is located at the cylinder 1 between two pistons 5
On inside, two crank arms 7 for being connected respectively to the bent axle 2 of the bosom position of cylinder 1, and at two directions of crank arm 7
Where the same diameter on straight line, placement direction is on the contrary, realize that piston 5 is taken exercises the relative reciprocating motion in direction.Bent axle 2 is axially
Upper two turning end are arranged on cylinder side wall, and wherein one end is connected with the hand cranking handle 6 outside cylinder 1.
Unidirectional venthole 3 and one-way air inlet hole are provided with the side wall of cylinder 1, remaining position is sealed, it is ensured that air tight.
Unidirectional venthole 3 is arranged on the centre position of cylinder 1, after gas is compressed, and is discharged by unidirectional venthole 3 inside cylinder 1, leads to
Cross tracheae to enter inside tire, for giving the inflation of the devices such as tire, balloon.One-way air inlet hole may be provided at the side wall of cylinder 1, also may be used
It is arranged on piston 5, for making ambient atmosphere enter inside cylinder 1.
A kind of hand air pump that the present embodiment is provided, due to small volume, efficiency high is used as portable inflator
For giving the inflation of the devices such as tire, balloon.The unidirectional venthole 3 of hand air pump is passed through into escape pipe and tire or gas first
The devices such as ball are connected, and then shake hand cranking handle 6 to a direction, hand cranking handle 6 is rotated with dynamic crankshaft 2.The bent axle 2 of rotation
The catch bar 4 on crank arm 7 is driven to move reciprocatingly., can because two position Relative distributions of crank arm 7 are in the both sides of bent axle 2
Realize the direction of motion of catch bar 4 relatively or on the contrary, make the direction of motion of two pistons 5 relative or opposite.Transported when piston 5 is relative
When dynamic, gas is compressed between two pistons 5, and then pressure rise enters airway tube by unidirectional venthole 3, subsequently into
Into tire.When 5 counter motion of piston, air pressure is reduced between two pistons 5, and ambient atmos enter two by one-way air inlet hole
Region between individual piston 5, for gas compression next time.Baffle of porous baffle 8 is provided at both ends with cylinder 1, extraneous foreign matter is prevented
Into cylinder 1, motion or the reduction air-tightness of piston 5 of piston 5 are hindered.
Because two pistons 5 in the inside of cylinder 1 are moved simultaneously, inner air is compressed jointly, so this hand air pump
Than same size cylinder inflator inflate it is more efficient, can also using reduced size hand air pump realize quickly fill
Gas, is convenient for carrying.And the catch bar 4 and bent axle 2 that piston 5 is connected in the hand air pump are in the internal motion of cylinder 1, institute
Will not also occupy bigger working space in the hand air pump course of work.
The respective embodiments described above are to realize specific embodiment of the utility model, and one of ordinary skill in the art can manage
Solution, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
