Abstract

The shaking type suction pump is a kind of manual water supply instrument, is made of crankcase, piston cylinder, bent axle, piston, rocking handle etc.It has changed traditional hand-operated suction pump into the bent axle shaking type, and has adopted the form of closing cap, and being fit to vast rural area does not have tap water area water supply usefulness.

Description

Hand-operated water pump

The utility model belongs to a kind of civilian well suction pump class.

Existing suction pump mostly adopts the hand-operated suction pump, and the shortcoming of this pump is to manipulate time effort, and pumping load is little, and lift is low, and since this pump suitable for reading be open-ended, can not reach sanitary standard so extract the water quality of water out.

The purpose of this utility model is: for people provide a kind of totally enclosed, the rapid operation lift is high, and manual water supply instrument that can a plurality of user is benefited by a bite beverage well.

The utility model is formed by casting of metals, by oblate crankcase, and the bent axle of band rocking handle and flywheel, piston, the pump that several sections such as water pump neck and piston are formed

Below in conjunction with accompanying drawing the structure of this model utility is given detailed introduction:

Accompanying drawing 1 is a structural representation of the present utility model.

(1) is crankcase in the drawings, and its shape is oblate, and it is divided into the oblateness of two make-ups up and down, has the edge that a circle protrudes round mouth on the limit of the round mouth that top is oblate.Half oblate edge of protruding round mouth that also is provided with suitable for reading, bottom, two protrusions are along all rectangular.Be provided with the round bearing groove of No. 305 bearings of packing in the middle of two long limits on rectangle edge, half oblate bottom, bottom is the slightly outlet pipe of top of a contraction mouth that is connected with piston cylinder (2) and contraction mouth, up and down two connections between oblate lean against protrusion along two bolts of last usefulness and two collar-shaped hinges at rectangle along fixing on the minor face.Oblate the going up at crankcase (1) in bottom just can form one and can open the closing cap that lifts like this.The effect of this lid is convenient to install bent axle and piston, also plays the effect of sanitation and hygiene to holding water in crankcase (1) simultaneously.Be columnar piston cylinder (2) and funnel shape water pump neck (3) below the crankcase (1), the connection between them all is to use four bolt respectively by the rectangle edge that the jointing edge protrudes.Piston cylinder (2) moves piston in cylinder body, water pump neck (3) is to save diversion.In crankcase (1) bent axle (4), its structure is with two metal flywheels (5) and the transverse axis that fuses with a side of flywheel (5) respectively by flywheel (5) center, and the axle two ends is enclosed within on the bearing that the bearing groove on the crankcase (1) is installed, there is an end transverse axis head to lean out bearing as L shaped rocking handle (13) is installed, near the surrounding edge of flywheel (5), bore an open-work and pass this hole, so just formed a complete bent axle (4) with a cylindrical flywheel connecting rod (9) to the core wheel direction.Piston (6) is columnar, its outer wall is to contact with piston cylinder (2) by the piston sleeve (7) at three steels in the bottom of outer wall, the shape of piston (6) is cylindrical, the circle suction hole of two symmetries is arranged at the bottom of cylinder, be cast with the fan-shaped pilaster (8) that fuses with an inwall on the tube inwall of in the tube and bottom two suctions hole formation vertical crossed lines, a drilled hole of inserting a cylindrical piston transverse axis (10), the upper end of pilaster (8).Around the cylinder inner bottom part two suction holes be and the hollow column casing of piston (6) bottom one, put a globule (metal or glass) in the column casing into, filament of column casing usefulness suitable for reading blocks thick stick and scurries to bottle up the outer of spheroid.Be to be connected going up connecting rod (11) at piston transverse axis (10) between bent axle (4) and piston (6) at the last end of flywheel connecting rod (9) by one one end, the bucket shin mouth of funnel shape water pump neck (3) is provided with a cylindrical shape well butterfly valve (12) that spins by silk braid with the shin mouth, the bottom of well butterfly valve (12) is a circular hole, is stamped big glass spheres on the circular hole.Its effect is that block water refluxes.

The utility model is that a kind of solution rural area does not have running water and level of ground water is lower, and the circumference region only has a bite well and the water supply instrument of water lift difficulty, and it is applicable to the sprinkling irrigation water supply usefulness such as rural households, booth, greenhouse. Do not need the energy, this pump is easy to use and reliable, and is cheap, and technology is simple, can promote the use of widely in the rural area.

Claims (1)
