Abstract
The utility model discloses a manual pump which comprises a dustproof ring, an end closure, an outlet pipe, a piston barrel, a piston, an inlet tube, a stop delivering ball, a gasket and a screw rod, wherein the pump is fixed on the wellbay via the screw and the end closure pushes down the dustproof ring which is matched with a piston rod with a shrink range and is tightly arranged in the groove of the end closure, but the piston rod can be moved up and down under a role of external force to prevent impurities or dusts from being entered. The piston rod and the piston are connected via the screw rod and the gasket. The stop delivering ball is arranged at the pipe nozzle and moves along with the upanddown moving cylinder rod. Because the end of the pump adopts such a kind of dustproof method, the pump avoids the dusts or impurities from entering into water to cause unsanitary water and is also characterized in simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of liquid and stops feedway, particularly a kind of hand suction pump.。
Background technique
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.This suction pump is owing to be placed on the outside for a long time, and its defective is that dust is more in the water quality, and because of piston cylinder top is open type, dust can fall at any time.
Summary of the invention
The utility model be to solve existing suction pump can't the dust-tight problem, and provide a kind of a kind of hand suction pump that prevents that dust from entering.
For achieving the above object, the technical solution of the utility model is:
A kind of hand suction pump, comprise dust ring, end cap, outlet pipe, piston cylinder, piston rod, piston, intake pipe, only pass ball, packing ring, screw rod, suction pump is fixed on the raised platform around a well by screw, end cap is pushed down dust ring, and dust ring cooperates with the piston rod that magnitude of interference is arranged, and in the groove of the end cap of tightly packing into, but piston rod can move up and down under the effect of external force, thereby prevented entering of impurity, dust.Piston rod is connected with packing ring by screw rod with piston, only passs ball and places intake pipe mouth of pipe place, moves up and down work along with piston rod.
The utility model has avoided dust, impurity to enter in the water owing to adopt the dustproof means of this kind in the end of suction pump, causes the unhygienic of water, and has characteristics such as simple in structure, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of handlance pump comprises dust ring 1, end cap 2, outlet pipe 3, piston cylinder 4, piston rod 5, piston 6, intake pipe 7, only passs ball 8, packing ring 9, screw rod 10, suction pump is fixed on the raised platform around a well by screw, end cap is pushed down dust ring, and dust ring cooperates with the piston rod 5 that magnitude of interference is arranged, and in the groove of the end cap 2 of tightly packing into, but piston rod 5 can move up and down under the effect of external force, thereby prevented entering of impurity, dust.Piston rod 5 is connected with packing ring 9 by screw rod 10 with piston 6, only passs ball 8 and places intake pipe 7 mouth of pipe places, moves up and down work along with piston rod.
