Abstract
The utility model discloses a hand oil and water pump, which is particularly suitable for filling oil to motor vehicles and pumping water which is drained in areas without motive power. The hand oil and water pump is mainly composed of a bearing, bearing blocks, a pump body, a rotating shaft and a blade, wherein, the bearing blocks 3, 7 are fixed on the both ends of the pump body through screw-bolts, the inner wall of the pump body 6 is processed into an ellipse, a shaft 5 and a shaft 12 which are arranged on the rotating shaft 11 cause the blade 6 to be supported on the elliptical wall of the pump body, and the blade is moved along the elliptical trace, which exhausts the air in the pump body to suck out the oil or water. The utility model has the advantages of simple structure, convenient installation, small size, light weight, low cost, power saving and labor saving, the utility model can be manufactured into serial products according to requirements, and the utility model is suitable for the areas without motive power.
Description
The utility model is a kind of hand oil water pump, is particularly useful for the oiling of motor vehicle and the pump drainage water in unpowered area.
Used oil water pump great majority are to finish the pump drainage profit with electric drive at present.Just can't use for motorless area, the motor vehicle driver who has is not having the situation of gas station, on the way need to refuel the method also take out with mouth for car, Patent Office of the People's Republic of China discloses exercise question and has been " a kind of manpower, Animal-drawn water pump ", its pump housing interior wall construction is spherical, blade is arc, and this water pump has solved under the motorless situation can finish the work of drawing water, but the pump housing and blade processing are complicated.
The purpose of this utility model is that a kind of hand oil water pump will be provided, and it is simple in structure, and volume is little, and is in light weight, and the pump housing and blade processing are simple, but simultaneously as required positive and negative direction rotate and reach same effect.During use, just can easily oil or water be extracted out as long as shake handle gently, the fast flow of rotating speed is big, and rotating speed slug flow amount is little.This pump electricity-saving labor-saving is widely used in unpowered area.
The utility model is to realize like this, mainly by bearing 2,9, bearing support 3,7, the pump housing 4, rotating shaft 11, blade 6 and axle 5,12 are formed, bearing 2,9 is contained in respectively in the hole of bearing support 3,7 small ends, rotating shaft 11 is tightly packed in the bearing 2 by pump housing endoporus, in the bearing support 7 dress rotating shafts 11, bearing support 3, bearing support 7 are fixed by bolts on the two ends of the pump housing, bearing cover 1,10 is fixed on the little end surface of bearing support 3,7, and the pump housing 4 of this pump is cylindrical body, and its inwall is oval, blade moves along elliptical path under the drive of rotating shaft.
Be elaborated below in conjunction with drawings and Examples:
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is Figure 1A-A view.
Fig. 3 is blade master, right elevation.
With reference among above each figure, bearing support 3,7 is T-shape, cylinder iron one-step casting moulding or single injection-molded, and bearing 2,9 is contained in respectively in the bearing support 3,7.Bearing cover 1,10 is screwed on bearing support 3,7 microcephalies' end face, two end cap casting or molding and forming, the pump housing 4 one-step castings or injection molded.The cylindrical of the pump housing is cylindrical body, and its inwall is oval, so that blade moves according to oval-shaped track.Also be drilled with into and out of the profit mouth at pump housing wall.Rotating shaft 11 usefulness round steel process, and are drilled with two orthogonal and disjoint through holes near the rotating shaft middle part.Have at an end mill of rotating shaft square so that make suit upper handle simultaneously.Axle 5, axle 12 are contained in the hole at rotating shaft middle part, and diaxon is slidingly matched at Kong Zhongwei.Blade 6 is 4 and processes by the high-quality steel that blade is a cuboid, is processed with circular arc on an end face on long limit, blade heads on by axle 5, axle 12, it can be abutted against on the pump housing inwall, sealing gasket 8 is housed, spill with grease proofing, water at the endoporus oral area of the big end surface of bearing support 7.
When using the utility model, bearing 2,9 is tightly packed in the bearing support 3,7, then axle 5, axle 12 are contained in the hole at rotating shaft 11 middle parts, two holes are orthogonal and non-intersect, and bearing support 3 is fixed by bolts on the end face of the pump housing 4.The rotating shaft 11 that axle 5, axle 12 are housed is equipped with the bearing support 7 of bearing 9 and sealing gasket 8 by being tightly packed in the pump housing in the bearing 2, by an end of rotating shaft 11 band square toes, is fixed by bolts to the other end of the pump housing 4.Again bearing cover 1,10 is fixed by bolts to respectively on the bearing support 3,7 at last.
At needs during with the oil pumping of this pump, water, taper knob is contained on the square toes of rotating shaft 11, clockwise rotates rotating shaft 11 lightly, the blade that is headed on by axle 5,12 and then rotates, blade moves along elliptical path in the pump housing, when the slowly oval rotation in edge of blade, blade ejects axle at leisure in the opposite direction, and this moment, axle promoted the blade of the other end again, shake rotating shaft continuously like this, blade is discharged the air in the pump housing, forms vacuum in the pump housing with oil or water sucking-off, discharges by output tube again.Same handle is rotated counterclockwise also can reach same effect, only needs input, goes out pipe and exchange.When the driver is group refueling, as has added also and rotating shaft can have been reversed, the oil of adding is extracted out again made oil flow back to the original place.
Reached designing requirement fully through this pump on probation, have simple in structure, easy for installation, advantage such as volume is little, and is in light weight, and price is low.And can make series product as required, be widely used in unpowered area.
