Abstract

The utility model belongs to fluid delivery equipment or a fluid delivery device, which particularly relates to a hand oil pump. The hand oil pump mainly solves the maneuver oil well pump of prior art of complicated structure and high cost while the hand oil pump has less functions, and inconvenient use. The hand oil pump mainly solves the maneuver oil well pump of prior art of complicated structure and high cost while a hand oil pump has less functions, and inconvenient use. The utility model is characterized in that an oil discharge pipe is connected with a plunger, and inner holes are communicated; the inner chamber of the plunger and a sphere form an oil discharge one-way valve; an oil inlet pipe and the other sphere form an oil-entering one-way valve. The oil discharge pipe is pulled repeatedly, and then oil is withdrawn. The utility model can be used for delivering fuels, lubrication oil and other liquid.

Description

Hand oil pump

The utility model belongs to a kind of equipment for liquid transportation or device, particularly a kind of manual oil well pump.

In the prior art, the oil well pump of use generally divides two kinds, and a kind of is motor pump, this shortcoming is, can have usefulness under the condition of power, and the cost height, complex structure, and the general hand pump function of using is few, uses trouble, goes into relatively difficulty of eminence for the oil pump that makes lower.

The purpose of this utility model is, designs a kind of simple in structurely, easy to use, and cost is low, can be with eminence oil, and pump again can be with the oil of lower to lower, and pump is to the manual oil well pump of eminence.

The purpose of this utility model is to realize like this, oil outlet tube connects with piston in the pump housing, and the center hole of piston and inner chamber communicate with oil outlet tube, and the inner chamber of piston and spheroid constitute fuel-displaced one-way valve, oil inlet pipe connects with the other end of pump housing pipe, and oil inlet pipe inner chamber and another spheroid constitute in line check valve.

Below in conjunction with accompanying drawing the utility model is described.

Accompanying drawing is the utility model structural representation.

Referring to accompanying drawing, the flexible pipe that inserts in the fluid is connected with the A mouth of oil inlet pipe 6, armrest is moving upwards to be carried oil outlet tube 1, at this moment spheroid 8 is owing to suction functions in the pump housing pipe 3 make progress, the A mouth is opened, be that in line check valve is opened, spheroid 5 is by action of gravity, piston 4 center holes are closed, it is fuel-displaced closed check valve, after oil outlet tube 1 drives the upper end of piston 4 motion row pump housing pipes 3, be full of fluid in the pump housing pipe 3, at this moment extrude oil pipe 1 downwards, spheroid 8 is under the 3 inner fluid pressure effects of pump housing pipe, the A mouth is closed, be that in line check valve is closed, and spheroid 5 is under the 3 inner fluid pressure effects of pump housing pipe, piston 4 center holes are opened, promptly fuel-displaced one-way valve opens, pump housing pipe 3 inner fluids can flow out from oil outlet tube 1, if on hoisting the pump oil require from lower, spur oil outlet tube 1 down repeatedly, if pump oil only needs from high to lower, under spur oil outlet tube 1 after, fluid can flow out in pump continuously by siphon principle, in order to make the pump in the work stop pump oil, at pump housing pipe 3 oil inlet ends joint with holes is housed and ends plate 7, in the time of need stopping pump oil, extrude oil pipe 1 downwards, ending plate 7 up to joint closes the center hole of piston 4, plate 7 can make fluid flow through in order only to save, and has oil-through hole at periphery, and is clean for the oil that pumps is filtered, on piston 4, be provided with filter screen 9, in pump housing pipe 3, also be provided with spring 2 and make the oil outlet tube 1 laborsaving convenience that resets.

The utlity model has simple in structurely, easy to use, cost is low, and function is many, and the efficient height is a kind of comparatively ideal manual oil well pump, can be widely used in the conveying of fuel oil or lubricant oil, is specially adapted to the driver and carries with car.

Claims
