Abstract
The utility model relates to a double-suction pedal liquid pump, composed of a machine frame, a liquid cylinder, a piston, a one-way valve gate, a seat cushion, an armrest and a pedal drive mechanism. The utility model uses a horizontal liquid cylinder to replace two upright liquid cylinders of the existing pedal liquid pump. The both ends of the horizontal liquid cylinder are provided with a liquid inlet and a liquid outlet, and the channels of the both sides of the liquid inlet and the liquid outlet are provided with one-way valves. A connecting draw rod is arranged on the piston and is connected with the pedal drive mechanism, and the connecting draw rod drives the piston to reciprocate in the liquid cylinder under the control of the pedal drive mechanism to realize double suction and drainage procedures which are finished by one reciprocating running of the piston.
Description
The utility model belongs to a kind of novel liquid pump, and it is applicable to the pump drainage of water, oil and chemical liquid raw material.
Existing foot pump generally is two vertical cylinder bodies, and its method of operation is a twin-tub single suction formula, in each cylinder body, when piston makes a round trip, can only realize that one inhales a row that is:, and efficient is lower, and cylinder body mostly is cast member, and inconvenience is carried.
The purpose of this utility model is: design a kind of novel foot-operated liquid pump, it can improve the efficient of foot-operated liquid pump.
The utility model is achieved in that a kind of double-sucking type rides liquid pump, form by frame, fluid cylinder, piston, one-way cock, seat cushion, handrail, footstep mechanism, its piston two ends all communicate with liquid entering hole and liquid outlet, and an one-way cock is set in passage separately, the cylinder lever connecting rod that is provided with on the piston links to each other with pedal transmission mechanism, and piston can be reciprocating in fluid cylinder under the drive of pedal transmission mechanism.
Advantage of the present utility model is: it replaces two vertical fluid cylinders of existing foot-operated liquid pump with a horizontal fluid cylinder, and simultaneously, piston to-and-fro motion in fluid cylinder once can be finished the process of twice suction, improve the efficient of foot-operated liquid pump.
Figure one is the utility model embodiment's a front view;
Figure two is side views of the utility model embodiment;
Figure three is pump housing schematic diagrams.
Figure four is the pedal transmission mechanisms among another embodiment of the utility model.
Following structure accompanying drawing is further described the utility model embodiment.
By figure one, figure two as seen, the double-sucking type Pedal water pump mainly contains frame (8), the pump housing (6), lever (3), foot-operated (4), cushion (2), draws and hold up dual-purpose handrail (1), pulley (5), rope (13) to form, liquid entering hole (9), liquid outlet (10) and cylinder lever connecting rod (12) are arranged on the pump housing, for ease of moving, on the frame (8) of liquid entering hole (9) one sides, adjustable tail wheel (7) is housed.
By figure three as seen, the pump housing (6) mainly is made up of fluid cylinder, piston (11), cylinder lever connecting rod (12), liquid entering hole (9), liquid outlet (10) and one-way cock (14), (15), (16), (17), in the present embodiment, the pump housing (6) and piston (11) are all made by the PVC engineering plastics.
Working procedure of the present utility model is: before use, pack up tail wheel (7) earlier, situation according to the user, adjust seat cushion (2) and draw the height of holding up dual-purpose handrail (1), connect into, the indusion tube of liquid outlet, and the liquid entering hole water pipe placed liquid, the user is seated on the seat cushion (2), with both feet treadle (4), under the effect of lever (3), by the effect of rope (13) and cylinder lever connecting rod (12), it is reciprocating in fluid cylinder to drive piston (11), when piston (11) when left end moves right, fluid cylinder left end degree of vacuum increases, and under atmospheric effect, one-way valve (14) is opened, (15) close, liquid (9) sucks the fluid cylinder left side from liquid entering hole; When piston (11) from right-hand member during to left movement, will compress the liquid that has entered left end, its pressure be increased, under the effect of hydraulic pressure, making one-way valve (14) close (15) opens, liquid is discharged from liquid outlet (10), simultaneously, because this moment, fluid cylinder right side volume increased, its degree of vacuum is risen, under the effect of air pressure, one-way valve (17) is opened, (16) are closed, and makes liquid suck the fluid cylinder right side from liquid entering hole (9); When piston (11) once more from left end when right-hand member moves, will repeat said process, the liquid on fluid cylinder right side is discharged from liquid port (10), simultaneously liquid is sucked the fluid cylinder left side from liquid entering hole, and so forth, make liquid suck the pump housing (6) from liquid entering hole (9) continuously, discharge the pump housing (6) from liquid port (10) again.After finishing using, to fail liquid-discharging tube and receive and to enclose on frame,, put down and fixedly be located at the tail wheel (7) on the frame (8) of liquid entering hole (9) both sides with standby, dual-purpose handrail (1) with pulling (pushing away), the foot-operated liquid pump of double-sucking type moves under artificial traction.
Figure four has provided another embodiment's of the utility model foot-operated type of belt drive, in this driving mechanism, the cylinder lever connecting rod (12) that is located on the piston (11) stretches out after the pump housing (6), an external connecting rod (19), join by connecting rod (19) and the bent axle (18) that is located at the pump housing one end, bent axle is arranged on the bent axle support, and links to each other with pedal lever 3, is ridden (4) and drives.The working procedure of this pedal transmission mechanism is, step foot-operated (4), drive bent axle (18) run-in synchronism by pedal lever, become rotatablely moving of bent axle (18) by connecting rod (19) and be the to-and-fro motion of cylinder lever connecting rod (12), thereby drive piston (11) to-and-fro motion in fluid cylinder, realize the entire work process that embodiment one is mentioned.
