Abstract
The utility model relates to a hand vacuum pump which comprises a pressure rod, a piston barrel, a piston rod, a piston, a water pumping pipe, a water outlet pipe, a supporting rod, etc., wherein, the top of the piston barrel is provided with a dust protective cover, the piston rod is sheathed with a spring on the outer side of the piston barrel, and both ends of the supporting rod are respectively hinged with the outer wall of the piston barrel and the pressure rod. The utility model has the advantages of sanitary, labor saving, high efficiency, and long service life.
Description
The utility model relates to a kind of liquid transporting apparatus, particularly a kind of hand vacuum pump.
At present in the area that does not have tap water, a kind of easy manual pumping pump is adopted in water intaking in the well, this suction pump is simple in structure, it comprises depression bar, piston cylinder, base, piston rod, piston, only passs valve, turnover water pipe etc., one end and the piston rod of depression bar are hinged, the middle part of depression bar is hinged on the fixing support rack, and upper and lower mobile depression bar just can be extracted water out from well.
The defective of this suction pump is: 1, health not too, because of piston cylinder top is open type, dust can fall at any time.2, efficient is not high, because piston rod swings when moving up and down depression bar, causes piston seal not tight, and is relatively more serious to wearing for piston in addition yet, influences working life.
The purpose of this utility model is to overcome above-mentioned defective a kind of hand vacuum pump is provided.
The purpose of this utility model realizes by following scheme:
Design a kind of hand vacuum pump, it comprises underframe, drinking-water pipe, outlet pipe, piston cylinder, piston rod, piston, depression bar, depression bar and piston tube are hinged in the end, and the mouth of pipe place that drinking-water pipe enters piston cylinder establishes only passs ball, it is characterized in that the piston cylinder top is provided with dust cover; The depression bar middle part is hinged with a pole hinged with the piston cylinder outer wall; Piston rod part outside piston cylinder is with spring.
Compared with the prior art the utility model has health, laborsaving, characteristics that the efficient of drawing water is high.
Fig. 1 is the utility model embodiment's an outside schematic representation;
Fig. 2 is the utility model embodiment's a internal structural map.
Below the contrast accompanying drawing is described in more detail structure of the present utility model by embodiment.
