CN2573720Y - Hand piston oil pump - Google Patents

Abstract

The utility model relates to a hand-operated piston type oil pump which is a novel tool for charging oil out of an oil barrel in a split mode. The utility model utilizes a pump principle and adopts the lever force of a handle to indirectly drive a piston to do reciprocating movement to generate vacuum, and thus, the oil is sucked out of the oil barrel. The hand-operated piston type oil pump of the utility model is characterized in that the lower end of a pump body of the utility model is provided with a threaded rod connector 7 with the same diameter with that of the mouth of an upper end cover of the oil barrel; after the pump body 1 of the utility model is tightly screwed, a lengthened piece 8 is naturally inserted at the bottom of the oil barrel. The utility model has the advantages of convenient disassembly and assembly, labor saving, obvious efficiency enhancement and low manufacturing cost is low, and is one of ideal tools for charging the oil in a split mode.

Description

Manual displacement oil pump

(1) technical field

The manual displacement oil pump of the utility model relates to a kind of instrument that packing oils is come out from oil drum.

(2) background technique

Existing instrument from oil drum packing oils has two kinds of forms: first kind is cried " oil pulls son ", it is the epitome of Ancient Chinese for the bright car in hole, it is the galvanized iron product that the tinsmith cold-working beats out, it by a diameter less than the oil drum cap mouth, length is simplified greater than the galvanized iron of oil drum height, the centre hauls the piston composition that iron sheet is made with an iron wire, 900 centimetres of the strokes of piston (equaling the height of oil drum), because piston stroke up and down reciprocatingly is too big, and people's arm falls short of, the another hand also must be pushed down cylindrical shell, whole cylindrical shell is and then up lifted when preventing that piston from up moving, two hands that work together are all very hard, in addition, exhaust in the tube of oil back at every turn and also deposited a lot of oil, must back down the one-way valve of cylindrical shell lower end with a finger, oils could withdraw from cylindrical shell, the big and trouble of waste, and efficient is low again.

Second kind is the manual gear pump, owing to adopted the gear acceleration, hand rotation is got up gruelling, and poor sealing performance, all to irritate some oil before each oil pumping and enter to make " introduction ", seal, idle running a period of time just can draw up oil comes, and trouble efficient is also low.

(3) model utility content

The technical problem that the manual displacement oil pump of the utility model will solve is: the principle of utilizing pump, drive the small distance movement that piston is done oil pumping indirectly by shouldering bar, the manual displacement oil pump of the utility model is to constitute like this: it comprises pump body, the pump housing is the important component part of this oil pump, handle adopts crank-type, people's height of standing equates with oil drum like this, hand gets up laborsaving, connecting rod is to drive the piston acting, piston is the core of this oil pump, up and down reciprocatingly produce vacuum by it, depended on pressure squeezed it and opens when valve down moved at piston, oils up comes up, one-way valve is opened it by suction when piston up moves, and pressure was closed it when piston down moved, and returns oil drum by oils, go round and begin again, reached the purpose of continuous oil pumping.Major character of the present utility model is: connector is equipped with in this oil pump lower end, and connector plays the effect of forming a connecting link; Connector top thread is connected with pump body lower end thread, connector bottom thread is connected with extension element, connector middle part thread is fixed in oil pump in the lid mouth thread of oil drum, piston in the pump housing, valve, one-way valve adopt the material of oil resistant rubber or other oil resistants to make, in order to keep atmospheric balance inside and outside the oil drum, bored an aperture in the lower end of connector, after oils was extracted out and gone, air constantly entered in the oil drum from aperture.The manual displacement oil pump of the utility model, owing to utilized and shoulder rod principle, so that hand gets up is lighter, in addition, because the net sectional area of the piston and the pump housing is big, the reciprocal vacuum capacity that produces of piston is also big, efficient has obviously improved.

(5) specifically implement formula

Referring now to accompanying drawing 1,2, the manual displacement oil pump of the utility model, concrete implementation step is: at first with the top thread 10 precession pump housings 1 lower end thread 9 of connector 7, bottom thread 13 with the thread 14 precession connectors 7 of extension element 8, open oil drum cap, extension element 8 is inserted in the oil drum, and with 12 pairs of good positions of middle part thread 11 and oil drum cap thread of connector 7, clockwise direction screws oil pump, up and down reciprocatingly press handle 2, drivening rod 3, connecting rod 3 drives piston 4, moves up and down, produce vacuum, valve 5 is closed automatically when piston 4 moves up and down and is squeezed out, and one-way valve 6 is opened by suction, and depended on pressure is closed, oils constantly up comes up, the air of outside goes round and begins again in replenishing into bucket from vent 15, can enter oil pumping work.The character that based on oil is different, volatility very strong after each work finishes as gasoline, kerosene, alcohol etc., counterclockwise direction unscrews oil pump, inclination pump body 1, and one-way valve 6 weightlessness are opened naturally, the surplus oil of depositing is all return in the oil drum in the pump housing 1, if diesel oil, lubricant oil, edible oil, because piston 4 sealings are very tight, if also there is oil in the oil drum, do not need oil pump is unloaded down the formality of refitting oil pump when having saved next the oil pumping.

The manual displacement oil pump of the utility model is simple in structure, and it is few, easy to use to spend, and is one of ideal tools of packing oils.

Claims (1)

1, a kind of manual displacement oil pump, it comprises: pump body (1), handle (2), connecting rod (3), piston (4), valve (5), one-way valve (6), extension element compositions such as (8), its special card is: connector (7) is equipped with in the lower end of oil pump, and connector (7) top thread is connected with pump body (1) lower end, and connector (7) bottom thread is connected with extension element (8), in oil drum cap mouth thread, extension element (8) is inserted into the oil drum bottom to the middle part thread of connector (7) with the oil pump overall fixed.
