Abstract

The utility model relates to a small pedal water pump, comprising a piston type pump body, the body of the small pedal water pump, a T-shaped piston rod and a pedal. The utility model is characterized in that the cylinder body of the piston type pump body is fixedly connected with the body of the small pedal water pump, the pedal swing rod of the pedal is in the hinged connection with the body of the small pedal water pump through a swing centering shaft, two pedal swing rods are in the T-shaped connection with the axial connecting rod of the piston type pump body through the shaft of the swing rod. The utility model has the advantages of simple structure and easy fabrication; the piston of the small pedal water pump is not provided with the idle motion, the motive power is not needed, and the utility model is suitable for the field irrigation of countryside without a power source and is suitable for a facility for domestic water.

Description

Pedal water pump

The utility model relates to a kind of water pump, particularly the manpower Pedal water pump.

Present water pump roughly is divided into centrifugal pump and plunger pump.This type of pump, because it is its rotating speed height, pressure are also bigger, solid all with the dynamic power machine drive, promptly by motor or internal-combustion engine drives.Simultaneously, this type of pump structure is also complicated, and accuracy of manufacturing requires also high.In addition, also there is the foot-operated suction engine of manpower in the rural area.But mostly be wooden, bulky, efficient is not high.Its suction journey and lift are also very low.In the non-transformer area, the peasant wants irrigation by pumping and the supply domestic water is difficult to use aforementioned water pump.

The purpose of the utility model is exactly to disclose a kind of small-sized Pedal water pump at the deficiency that has water pump now.This pump does not need power to drive, and has certain lift, thereby can solve irrigating by lifting water to a higher level with a water pump, etc. and the domestic water problem of areas without electricity peasant.

The purpose of the utility model realizes in the following way: it is to be fixedly connected by reciprocating pump body component and body 5.The foot-operated fork 10 usefulness swing centration axis 8 of pedal member and moving connection of body 5 hinges, foot-operated forks 10 of whiles two form tee T by fork axle 9 with the axial links 7 of reciprocating pump body component and connect (referring to accompanying drawing 2).Like this, when foot-operated foot treadle 17 in the above, piston 2 promptly begins to be moved to the left.At this moment, the left chamber draining of cylinder body 1, the water inlet of right chamber, simultaneously, another foot treadle 17 lifts.When depressing this foot treadle again, piston moves right, the draining of at this moment right chamber, the water inlet of left chamber.Arrive this, water pump is finished a complete pump water cycle.

The purpose of the utility model also can realize in the following way: the rubber plate 3 of respectively adorning a control water inlet and outlet at the upper and lower of reciprocating pump body component, on rubber plate 3, have the ligule otch, the water chamber 4 that water inlet and outlet is used is housed in the outside of rubber plate 3, upper water cavity body 4 is the water outlet cavity, and following water chamber 4 is the suction cavity.

The purpose of the utility model can also realize in the following way: pedal member is cascaded and constitutes cutting with scissors the circular hole that is connecting on two foot-operated forks 10, two foot-operated fork 10 usefulness swing axiss 9 and axial links 7 right-hand members on the frame 5 respectively with two swings centration axis 8, upper and lowers.

The purpose of the utility model can also realize in the following way: the tee T piston rod of this water pump is to wear a swing axis 9 to constitute in the right-hand member circular hole of axial links 7.Its tee T piston rod also can be an overall structure.

The purpose of the utility model can also realize in the following way: pedal member is with 17 movable connections of foot treadle by foot-operated fork 10 usefulness pedal screws 11.

Good effect of the present utility model is: this pump does not need the energy, and a people can step suction, and is so its applicability is strong, to the non-transformer rural area, particularly suitable.In addition, this pump structure is simple, easily manufactured, efficient is higher, and cost is also more cheap.

Drawing is described as follows:

1, cylinder body 2, piston

3, rubber plate 4, water chamber

5, body 6, saddle are transferred bar

7, axial links 8, swing centration axis

9, swing axis 10, foot-operated fork

11, pedal screw 12, the people plate that collapses

13, transfer bar frame 14, screw

15, fixed hole 16, saddle location jackscrew

17, foot treadle 18, screw

Below in conjunction with accompanying drawing the utility model is further described: with the water sucking mouth, lower end of pump.Insert in the water, the upper end water outlet connects water vessel or irrigation canal.When the foot-operated foot treadle 17 down of people, piston move in cylinder body 1, and at this moment water enters water sucting cavity the cylinder body 1 from water chamber down, and the water in the setting-out chamber is pressed into the upper water cavity body simultaneously at this moment, and is available.During two foot treadles of this pump moved down thereon, water pump all was in suction and hull-borne, does not have idle stroke, so its efficient is higher.

Claims

1, a kind of Pedal water pump, it is to be made of reciprocating pump body component, tee T piston rod part and pedal member, it is characterized in that: the cylinder body 1 and the body 5 of reciprocating pump body component are fixedly connected, the foot-operated fork 10 usefulness swing centration axis 8 of pedal member and moving connection of body 5 hinges, two foot-operated forks 10 form tee T by fork axle 9 with the axial links 7 of reciprocating pump body component and connect.

2, Pedal water pump according to claim 1 is characterized in that: the rubber plate 3 of respectively adorning a control water inlet and outlet up and down at the reciprocating pump body component, on rubber plate 3, have the ligule otch, and the water chamber 4 that water inlet and outlet is used is housed in the outside of rubber plate 3.

3, Pedal water pump according to claim 1 is characterized in that: with swing centration axis 8, cut with scissors the circular hole that is connecting on two foot-operated fork 10, two foot-operated fork 10 usefulness fork axles 9 and axial links 7 right-hand members respectively at upper and lower and be cascaded on frame 5.

4, Pedal water pump according to claim 1 is characterized in that: its tee T piston rod part is to constitute by penetrate a fork axle 9 in the right-hand member circular hole of axial links 7.
