Abstract

The utility model relates to a hand water pump belonging to piston type fluid machinery, which mainly solves the problem of fluid scooping under the condition of no electricity. The two cylinders on the casing body of the utility model are ranged in the central symmetry of a shaft, a pendulum handle is swung to operate a glide plug (the glide plug is an assembly), the working operation is pushed by a push rod and is returned by the pulling of an idle running ball gear, the fluid is exhausted by pushing of the matching of the screw nut of the glide plug and a seal ring, the fluid suction is completed by the liquid continuity or atmospheric pressure (air), and one suction valve and one exhaust valve are arranged. The utility model has the advantage of compact and novel structure, and is mainly used for pumping water from a tapping pipe. When the base is changed (picture 3), the hand water pump can be used as a water press well head; when the exhaust valve structure is moved into a cylinder head (picture 4), the hand water pump can be used for gas inflation.

Description

Manual water aspirator

The utility model belongs to fluid machinery, relates to a kind of improvement to the withdrawn fluid instrument.

At present, the a small amount of water lift from lower toward eminence, in the vast rural area that lacks electricity and other power, in the small towns that does not have the tap water facility, people use the winch bucket usually and are commonly called as the setting-out well head water lift of foreign well head, the tool profile that draws water that this kind is more ancient is very little bigger to the greatest extent, operation is heavy, inefficiency draws water, and be open drawing water, when drawing water easily by pollutions such as dusts, for the city dweller that the tap water facility is arranged, because the pressure of supply water deficiency also usually has water there be not water upstairs downstairs, people lack a kind of water fits small-sized, easy to use and solve these problems.

The purpose of this utility model provides a kind of small and exquisite easy to use, can manually draw well water, tap water, can be used as the manual water aspirator that the air-breathing instrument of inflation is used again.

The technical solution of the utility model is in the manual housing both sides of water aspirator a cylinder body to be installed respectively, utilize the pressure handle control lever shaft to drive that sliding plug moves reciprocatingly in the cylinder body, discharges purpose to reach fluid sucked.

Characteristics of the present utility model are that two cylinder bodies are fixedly mounted on respectively on the housing the axle center is the center symmetric arrays, pressure handle inserts in the axle head groove and by linking to each other with sliding plug group with the fixedly connected pendulum plate of axle, the connecting rod front end is contained in ball retaining and the sliding plug nut, sliding plug nut overcoat has Mi Quan, suction valve is contained in the housing ingress, the damping ball is housed in the valve, and it is corresponding with the cylinder cap inboard that working spring one end and the glue of expulsion valve seals the corresponding the other end.

Working principle of the present utility model and good effect are:

When with flexible pipe with suction valve with by after the water UNICOM of suctions, shaking pressure handle can be by sliding plug work with the connecting rod promotion that pin is connected of living of pendulum plate.When fluid is shifted to outer dead point at sliding plug, the Mi Quan that is abutted against on casing wall and the sliding plug nut pushes expulsion valve, the sliding plug when returning, because Mi Quan changes near sliding plug and casing wall, this moment, fluid was able to enter sliding plug front portion by the hole of sliding between plug nut and casing wall through sliding through hole beyond the Great Wall.Constantly shake the pressure handle fluid and promptly constantly enter, discharge through expulsion valve from sliding plug front from sliding plug back.Its good effect is: for the town dweller provides a kind of small instruments and tools that draws water in the water tap easy to use.Solve the rural area and carry well water use winch, the substitute products of setting-out well head overcome background technique and expose the water lift drawback, and this product design are small and exquisite, and is easy to use, makes without the timber conservation metal; For society develops a kind of portable hand-held inflation, air-breathing instrument.This is novel than background technique winch, setting-out well head and pump, bigger using scope is arranged, can not only draw the liquid of water or other similar water, the liquid that is drawn can also be utilized external hose to be sent to eminence and other places that needs, can inflate by gas again, also can use the occasion that to bleed.

Fig. 1 is a structural drawing of the present utility model;

The manual water aspirator of expression is made up of cylinder body 1, housing 2, protecgulum 3, axle 4, suction valve 5, base 6, pressure handle 8, pendulum plate 9, connecting rod 10, cylinder cap 11, sliding plug nut 13, sliding plug 14, close circle 15 in Fig. 1.Two cylinder bodies 1 are fixedly mounted on the both sides of housing 2 respectively, and be the center symmetry with the axle center of installation shaft on the housing, sliding plug nut 13 puts close circle 15 and is fixed as one with sliding plug 14 and constitutes sliding plug assembly with connecting rod 10 in the cylinder body, the sliding plug of this sliding plug working stroke Mi Quan cooperation nut blocks fluid with passage and is pushed to the outer dead point discharge by sliding plug, return stroke Mi Quan relies on sliding plug, make fluid enter outer dead point in the cylinder body through the hole between sliding plug nut and casing wall and sliding beyond the Great Wall through hole in the housing, discharge in order to next working stroke, orifice plate 18, gasket ring 19, glue envelope 20 and spring 21, be sandwiched in when cylinder cap 11 is installed in the seam of cylinder cap and cylinder body and form expulsion valve, this kind expulsion valve, spring sealedly in cylinder cap and glue envelope, do not contact the fluid of being carried, and and clearance volume minimum between sliding plug, fixedly connected with axle 4 in the middle of the pendulum plate 9, two ends and connecting rod 10 are hinged, the connecting rod the other end utilizes ball retaining 12 to be connected with sliding plug, the mounting hole that the reeded end of axle passes protecgulum is fitted in the reservation blind hole of housing by protecgulum, protecgulum and housing are screwed and are one, housing bottom is screwed on base, and the housing side has one to reserve mounting hole in order to suction valve to be installed.

When with flexible pipe with suction valve with absorbed water or after water tap is communicated with, pressure handle is inserted axle head, shake pressure handle and can promote the to-and-fro motion in cylinder body of sliding plug, thereby fluid is sucked housing by suction valve, discharge by expulsion valve through the half-duplex channel of sliding the plug group by the connecting rod hinged with putting plate.

The C-C sectional view of Fig. 2 Fig. 1, the expression expulsion valve is made up of orifice plate 18, gasket ring 19, glue envelope 20 and spring 21 among the figure, and its medi-spring 21 is enclosed within glue envelope 20 and the cylinder cap 11.
