Abstract

The utility model relates to a lubricant grease oil injection machine, which is especially suitable for grease oil injection used for lubricating. The utility model is composed of a gun head, a hand plunger pump, an oil supply pipe connecting the gun head and the hand plunger pump, a filter, and an oil supply device for supplying grease to the plunger pump. When a pressure lever is rocked by a hand so that a plunger is driven to make reciprocating movement, owing to the thrust function of a piston and a spring in the oil supply device, the grease is loaded into the plunger pump. After the grease is loaded into the oil supply pipe by the oilout end of the plunger pump, the grease passing through the filter is sent into the parts needing lubricating from the gun head. The utility model uses a dismountable combined type oil supply device, and thus, the utility model has the advantages that the oil filling is rapid and the quantity is sufficient, the grease is pure and without impurity after filtered by the filter, the gun head can not be blocked, and the lubricating effect is good.

Description

Efficient oil strain grease gun

The utility model relates to a kind of lubricant grease oiling facility, and it is specially adapted to the lubricated butter oiling of using.

Existing on the market at present grease gun; it is by the rifle head; hand piston pump; the oil supply pipeline that connects rifle head and hand piston pump; and the oil supplying device that butter is provided to plunger pump; because fuel tank in the oil supplying device and accumulation of energy tube link into an integrated entity and can not be split; therefore; butter can only inject from the fuel tank front end; and butter is because of being subjected to the influence of an interior resistance of air; very slow during injection; can't fill with; and the pull bar on the accumulation of energy tube draws to hang over when oiling and is subjected to the spring-back force effect in the elongated slot, makes pull bar usually slide to center hole, again butter is gone out to cause to leak waste from the extruding of fuel tank front end.Owing to have impurity unavoidably in the butter due to the various factors, cause the rifle head to stop up and can't work smoothly.

The purpose of this utility model is exactly that providing a kind of can inject fuel tank with butter fast in order to overcome above-mentioned shortcoming, improves annotate efficient and workmanship, avoids the rifle head to stop up, and reduces and leaks, and improves the efficient oil strain grease gun of oiling working environment.

The technical solution of the utility model is done in such a way that filter is installed in oil supply pipeline and the rifle head, and the oil supplying device of being made up of accumulation of energy tube and fuel tank adopts detachable combined.

The utlity model has following advantage, adopt detachable combined oil supplying device, not influenced by resistance of air, charge of oil is fast measured foot, and pull bar radially, axial restraint is reliable, leakage loss is few, grease has impurity unavoidably in store using, filter the pure and free from admixture of back grease through filter, the rifle head does not stop up, high lubricating effect.

Fig. 1 is the utility model structural drawing.

Fig. 2 is the utility model A-A cut-away view.

Among the figure 1, depression bar, 2, rocking handle, 3, plunger, 4, the Yx seal ring, 5, cover, 6, pump case, 7, hexagonal socket nut, 8, the rifle head, 9, filter, 10, oil pipe, 11, steel ball, 12, spring, 13, support mesh, 14, fuel tank, 15, the tube nut, 16, the YX seal ring, 17, piston, 18, the accumulation of energy tube, 19, pull bar, 20, spring, 21, cover, 22, shrinkage pool, 23, center hole, 24, elongated slot.

The utility model is to implement like this, the combined type fuel tank by fuel tank, accumulation of energy tube, piston and pull bar thereof, send oily spring, cover, a tube nut to form.Piston was scurried piston to the accumulation of energy tube by the sealing of Yx seal ring to prevent grease.Piston pulling rod is designed to " universal shaft coupling " formula three-stage structure, can be fixed by the partial center line behind the drawing-pressing spring like this and does not have the spring-back force effect, simultaneously, reduces the distortion of tilting of the piston and seal ring.Cover is mainly used in fixed drawing-rod.In order to make the pull bar can held stationary, at shrinkage pool of the other processing of cover center hole with bar footpath size.The processing elongated slot communicates between two holes.Groove width equals annular groove path on the pull bar.Pull bar is stuck on the cover elongated slot by annular groove on the bar like this, then is subjected to axial restraint, and pull rod slot is subjected to along falling into shrinkage pool again radially fixing simultaneously, thereby pull bar is fixing reliable.

Fuel tank is identical with spring energy-storage tube internal diameter.They connect (and two butt joint end faces are smooth seamless) by screw thread with the tube nut, form a removable oil tube.By thread size and the different requirements of tolerance, make fuel tank connect pine with the tube nut, make its dismounting flexible, so independently the fuel tank charge of oil is very convenient easily, and can gas shutoff in the tube, charge of oil is smooth and easy, the innage foot, at the fuel tank oil outlet end support mesh is installed in addition, grease drops when preventing charge of oil.During charge of oil, pull bar is hung in elongated slot and the shrinkage pool, pull down the accumulation of energy tube, after butter is filled with, load onto the accumulation of energy tube, again pull bar is hung on the central hole location.

Hand piston pump is by plunger and depression bar thereof, housing assembly, unidirectional composition such as cut down.Housing assembly is made up of Yx seal ring, cover, pump case.Yx seal ring and the working portion that overlaps the composition cylinder body are big Spielpassung between plunger and the cover, grease suction when its slit helps the plunger backhaul.Seal by the Yx seal ring when pressing oil.The Yx seal ring is installed in the annular groove of cover and pump case composition.Cover is to be fixed on the pump case by hexagonal socket nut, and the dismoutability of cover is convenient to the replacing of Yx seal ring.The oil outlet end of cover is processed into one-way valve seat, realizes unidirectional logical functional oil by steel ball and spring.Processing plunger guide hole on the pump case, plunger connects by pin with depression bar.Depression bar connects by rocking handle with pump case.It is reciprocating that hand dynamic pressure bar drives plunger, and grease is sent, and enters transport pipe.

Transport pipe is made up of rifle head, oil pipe and filter.Filter is installed in oil pipe and the rifle head, and it is by garden post helical spring (or porous garden post bucket), and filter screen and cutting ferrule are formed.Filter screen grows the net folding of spring one end and obturage (but spot welding etc.) around wrapping in the spring outside.Spring mainly plays supporting filter net and logical oil effect.The outer cutting ferrule that overlaps again of net.Rifle head and oil pipe are by scyewed joint, and they link and hold endoporus to be processed into taper.The two ends of cutting ferrule are held in respectively in the cone shape hole of oil pipe and rifle head, by the contraction of taper hole, make the cutting ferrule anchor ear live filter screen and spring and form filter.

When hand dynamic pressure bar drive plunger is reciprocating, because the accumulation of energy tube inner carrier in the oil supplying device and the thrust of spring, drier oil in the fuel tank is sent in the plunger pump, the oil outlet end of plunger pump is processed into one-way valve seat, after realizing that by steel ball and spring unidirectional logical oil enters oil supply pipeline, through oil purifier from the rifle head to required lubricating component in.
