Abstract
The utility model relates to a hand water pumping cylinder for a water pump, which comprises a crank handle (2), a support rod (3), a piston rod (15), a piston (19), a cylinder body (4) and a water inlet connector (8) of the water pump, wherein, a tiltable valve plate (21) is arranged between the cylinder body (4) and the water inlet connector (8) of the water pump; the upper part of the cylinder body (4) is provided with an annular groove (18). A screw (17) arranged on a piston cap (16) is matched with the annular groove (18), so that the piston cap (16) can rotate relatively to the cylinder body (4). The support rod (3) is fixed on the piston cap (16). The lower part of the cylinder body (4) is provided with a one-way exhaust device. After the structure is adopted, and when the crank handle (2) is pressed down, pressure in the cylinder body (4) exhausts compressed air through the one-way exhaust device, and reduces resistance for pressing down. The annular groove (18) is fitted with the screw (17) fixed on the piston cap (16), so that the crank handle (2) can be operated and used in different angles. The utility model has the advantages of simple structure, light hand feeling, convenient installation and operation, time saving, labor saving, etc.
Description
One, technical field
The invention relates to a kind of hand water plug, the improvement of the hand cylinder barrel that draws water that uses on particularly a kind of centrifugal water pump.
Two, background technique
Present centrifugal water pump at first wants water that the pump housing and intake pipe are filled in use, and just can start water pump and draw water, otherwise, just do not take out water.For this reason, the hand cylinder barrel that draws water is all mixed by many producers on water pump, shake wind, and the piston in the tube is moved up and down, and venting water inlet inner air tube draws water and fills; Yet the quality of exhaust depends on the seal degree of piston and cylindrical shell, and it is good more to seal, and the exhaust diversion is fast more, otherwise the exhaust diversion is just slow more; But it is good more to seal, and when piston moved down in tube, resistance was just big more, and the power of use also just needs big more.The present hand cylinder barrel that draws water that uses, its supporting rod is fixed on the cylindrical shell, and wind is installed a direction only, therefore also can only shake wind in a direction when operation, makes troubles for installing and using of user.
Three, summary of the invention
For overcome the existing hand resistance of the hand cylinder barrel that draws water of water pump big, install and use the disadvantage of inconvenience, the invention provides a kind of feel the hand cylinder barrel that draws water of water pump light, that can both operate in any one angle.The invention solves the technological scheme that its technical problem adopts and comprises wind, supporting rod, piston rod, piston, cylindrical shell, water pump water inlet connecting body, wind is fulcrum with the supporting rod, its end is connected with piston rod, piston is fixed on the piston rod and is arranged in the cylindrical shell, cylindrical shell is fixed on the water pump water inlet connecting body and by air outlet flue and is communicated with, be provided with turnover valve block at cylindrical shell and between water pump water inlet connecting body, the top of described cylindrical shell is provided with annular groove, the piston cap that is provided with suitable for reading at cylindrical shell, the screw that is arranged on the piston cap matches with annular groove, piston cap can be rotated relative to cylindrical shell, and supporting rod is fixed on the piston cap.
The bottom of described cylindrical shell is provided with unidirectional venting gas appliance.
After adopting said structure, when wind pressed down, the pressure in the cylindrical shell was discharged pressurized gas by unidirectional venting gas appliance, has reduced the resistance when pressing down; By the annular groove on the cylindrical shell be fixed on piston cap on the cooperating of screw, wind can both be manipulated in different angles; Have simple in structure, feel is light, advantage such as easy to install, time saving and energy saving.
Four, description of drawings
