Abstract
The utility model provides a two-way hand air pump consisting of a pump body, a shaft core connected with a piston, a cover body and two shifting shafts, wherein, the cover body is formed by the fixed connection between an upper cover with an inlet and an air outlet and a cover board with an inverting gas cell which consists of an inlet chamber and an outlet chamber which are divided by an isolation channel; the soleplates of the inlet chamber and the outlet chamber are respectively provided with a plurality of valves; the shifting shafts are respectively connected with one valve of the inlet chamber and the outlet chamber. Compared with the prior art, the utility model has the advantages of quick inflation, high efficiency, light weight and portability.
Description
Technical field:
The utility model relates to a kind of inflator pump, especially manual inflator pump.
Background technique:
At present, in daily life, people often will inflate some objects, and common inflator pump adopts the leather bucket structure usually, descend the push-and-pull piston rod on hand by using, reach the purpose of inflation, because this inflator pump can only be inflated under the action of drawing, under the action that pushes away, can only exit, so exist use not laborsaving, complex structure, and the shortcoming that is not easy to carry.
Technology contents:
The purpose of this utility model provides a kind of simple in structure, easy to use and can be implemented in to take out all to have when pressing and give vent to anger and the inflator pump of air-breathing effect.
The utility model is achieved in that a kind of two-way manual inflator pump, form by cylindrical shell, axle core, lid and two reversing shafts of being connected with piston, piston drives by the axle core and moves up and down in cylindrical shell, lid and cylindrical shell are closely affixed, lid is by being provided with into and out of the loam cake of pore and to have the cover plate of the air chamber that commutate mutual affixed and constitute, the commutation air chamber is by forming into and out of air chamber that isolation channel is separated, base plate into and out of air chamber is provided with several valves respectively, and reversing shaft is communicated with a valve into and out of air chamber respectively.
Described valve is to be made up of valve base and valve sheet, and the valve sheet of suction chamber is arranged on the lower end of valve base, and the valve sheet of discharge chamber is arranged on the upper end of valve base.
Between lid and cylindrical shell, diaphragm seal can be set, sealing cover is set on diaphragm seal.
The utility model is owing to adopted said structure, when inflator pump is bled, piston moves up, and air enters the piston lower end by inlet hole and reversing shaft, and the gas on piston top is discharged to the commutation air chamber by the valve of discharge chamber, when inflator pump is calmed the anger, piston moves down, and the gas of piston lower end carries out exhaust by reversing shaft and air outlet hole, and the gas on piston top is by the valve air inlet of suction chamber, so move in circles, air is continuously squeezed in the inflatable substrate.Compared with the prior art, the function that the utlity model has bidirection air intake and give vent to anger, inflation is fast, and efficient is high and in light weight, is easy to carry conveniently.
Description of drawings:
The schematic representation of the two-way manual inflator pump of the utility model shown in Figure 1;
The stereogram of the lid of the two-way manual inflator pump of the utility model shown in Figure 2;
The structural representation of the lid of the two-way manual inflator pump of the utility model shown in Figure 3.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to figure 1, the utility model is made up of cylindrical shell 5, axle core 2, piston 3, lid and two reversing shafts 6, piston 3 is fixedlyed connected with axle core 2, the upper end fixed handle of axle core 2, by push-and-pull to axle core 2, drive piston 3 and in cylindrical shell, move up and down, thereby the air in the inflator pump is entered in the inflatable substrate under the effect of piston 3.
Cylindrical shell 5 is closely affixed with lid, with reference to figure 2, lid is by being provided with into and out of the loam cake 1 of pore and the cover plate 4 that has an air chamber that commutates mutually by constituting from the merit screw is affixed, inlet hole 8 and air outlet hole 7 all are arranged on the upper end of loam cake 1, the air outlet hole 7 of lid connects charging air inlet, gas can be thrown in the inflatable substrate.With reference to figure 3, the commutation chamber is to be made up of suction chamber 14 and discharge chamber 13 that isolation channel 15 is separated, base plate into and out of air chamber 14,13 is provided with two valves respectively, valve is made up of valve base 10 and valve sheet 9, the valve sheet 9 of suction chamber is arranged on the lower end of valve base 10, and the valve sheet 9 of discharge chamber is arranged on the upper end of valve base 10.Reversing shaft 6 respectively with advance, one valve of discharge chamber is communicated with, reversing shaft 6 is a hollow tube, during use, piston with carrying on the axle core and on, at this moment, air enters piston 3 bottoms by inlet hole 8 and reversing shaft 6, the air on piston 3 tops enters the commutation chamber by a valve of discharge chamber, and enter in the inflatable substrate by air outlet hole 7, when inflator pump was calmed the anger, piston descended downwards with the axle core, and the air of piston bottom enters in the inflatable substrate by reversing shaft 6 and air outlet hole 7, piston 3 tops are then by the valve and inlet hole 8 inflations of suction chamber, thereby realize that inflator pump gives vent to anger and air-breathing effect taking out all to have when pressing.Diaphragm seal 11 is set between lid and cylindrical shell, and on diaphragm seal 11, sealing cover 12 is set, can strengthen air current sealed degree, prevent that air-flow from leaking.
The utility model inflation is fast, and efficient is high and in light weight, is easy to carry conveniently.
