Abstract
The utility model relates to a pedal air pump, which comprises an air cylinder having an air inlet and an air outlet, and a piston arranged in the air cylinder. The utility model is characterized in that the air outlet is provided with a steel ball stop valve, and an air storing and pressure reducing chamber is arranged outside the air cylinder; as the stop valve and the air storing and pressure reducing chamber are additionally arranged on the base of existing pedal air pumps, air reflux can be prevented from generating during the backward stroke of the piston, and thus the work efficiency of the air pump is enhanced; as the air storing and pressure reducing chamber is arranged, pressure can be rapidly discharged by an air discharging pipe, and thus the work strength of operators can be reduced, and the purpose of labor saving can be realized.
Description
The utility model is a kind of foot-operated air pump, and it is well-suited for high pressure tyre or other gas-filled type utensil replenishes pressurized gas.
The relief opening of the foot-operated air pump that uses does not have check valve at present, so can produce backflow when gas is in backward stroke of the piston when inflating for the object that does not have spool, working efficiency is reduced, existing in addition air pump does not have the gas storage storehouse, so because pneumatic tube can not very fast pressure release increase resistance, thereby make inflation hard.
The novel purpose of this use provides a kind of novel foot-operated air pump, and it can overcome existing shortcoming in the prior art, increases work efficiency, and reaches the labour-saving purpose.
The purpose of this utility model is achieved in that it comprises the cylinder that has relief opening and suction port and is installed in piston in the cylinder, it is characterized in that in exhaust ports a steel ball type check valve being installed, and is provided with in the outside of cylinder and accumulates gas decompression storehouse.
The utility model has been set up check valve and has been accumulate gas decompression storehouse on the basis of original foot-operated air pump, so when backward stroke of the piston, can not produce gas backstreaming, thereby improved the working efficiency of air pump, because the gas of accumulateing decompression storehouse has been arranged, make the exhaust duct can very fast pressure release, reduce operator's working strength, reached the labour-saving purpose.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a structural profile schematic representation of the present utility model.
Cylinder in the present embodiment adopts the double-walled cylinder, be inside cylinder wall 5 and outside cylinder wall 6, the centre is a working cylinder, piston 4 is installed, and be provided with suction port and relief opening, in exhaust ports steel ball type check valve 2 is installed, between the inside and outside cylinder wall for accumulateing gas decompression storehouse 3, it is connected with the relief opening of cylinder and the high pressure gas pipeline road 1 of air pump, and 7 is Returnning springs of piston among the figure.
