Abstract
The utility model relates to a grease gun, in particular to a manual grease gun, and discloses a pull rod tail portion air discharge grease gun, which comprises a grease storage cylinder. A piston and a spring are arranged inside the grease storage cylinder; a piston rod connected with the piston penetrates through the rear end of the grease storage cylinder; a level grease outlet mechanism is connected to the front end of the grease storage cylinder; an air discharge pull rod is arranged inside the hollow piston rod; and a gap is arranged between the air discharge pull rod and the piston rod. The technical scheme of the pull rod tail portion air discharge grease gun includes that the air discharge pull rod is arranged inside the piston rod; and when grease is filled into the grease storage cylinder, the grease storage cylinder can be filled up because air inside the grease storage cylinder can be discharged through the gap between the air discharge pull rod and the piston rod, thereby improving use efficiency and continuous grease output. Besides, two plunger cavities are arranged inside a plunger pump body; when the piston rod is pushed to squeeze the grease inside the grease storage cylinder out of the plunger pump body, air inside the plunger pump body can be discharged without continuously pressing an air discharge valve; and the grease gun is simple in operation and fine in air discharge effect.
Description
Technical field
The utility model relates to grease gun, relates in particular to hand grease gun.
Background technique
The conventional manual grease gun comprises oil storage cylinder, is loaded on the thrust mechanism of being made up of piston, piston rod and spring of oil storage cylinder rear end, and the fuel-displaced mechanism of Lever type that is connected with the oil storage cylinder front end.Before the use, need to take off the fuel-displaced mechanism of Lever type, in oil storage cylinder, load butter from oil storage cylinder.Filling generally is to divide this to insert the little agglomerate of butter, perhaps adopts special grease gun charging device.When no matter adopting the sort of mode to load butter in oil storage cylinder, can't discharge because of air in the oil storage cylinder, oil storage cylinder can't fill up, and reduces utilization efficiency, and is fuel-displaced discontinuous.
In addition, the fuel-displaced mechanism of the Lever type of conventional manual grease gun comprises plunges pump body, and plunges pump body comprises a plunger and a plunger cavity, and the plunger cavity is provided with drain tap.When the promotion piston rod is squeezed into plunges pump body with the butter in the oil storage cylinder, need constantly push drain tap, the air in the plunges pump body is discharged, complicated operation, exhaust effect is poor.
Summary of the invention
The utility model can't be discharged because of air in the oil storage cylinder during butter at the filling in oil storage cylinder that exists in the prior art, and oil storage cylinder can't fill up, and reduces utilization efficiency, and is fuel-displaced discontinuous; When the promotion piston rod is squeezed into plunges pump body with the butter in the oil storage cylinder, need constantly push drain tap, make the air in the plunges pump body discharge complicated operation, the deficiency of exhaust effect difference, provide and be provided with the exhaust pull bar in a kind of piston rod, when loading butter in oil storage cylinder, can discharge by the gap of exhaust pull bar and piston rod because of air in the oil storage cylinder, oil storage cylinder can fill up, improve utilization efficiency, fuel-displaced continuous; Two plunger cavitys are set in the plunges pump body, when the promotion piston rod is squeezed into plunges pump body with the butter in the oil storage cylinder, need not constantly to push drain tap, the air in the plunges pump body is discharged, simple to operate, the pull-rod type afterbody venting grease gun of good exhaust effect.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Pull-rod type afterbody venting grease gun, comprise oil storage cylinder, be provided with piston and spring in the oil storage cylinder, the piston rod that links to each other with piston passes the rear end of oil storage cylinder, the front end of oil storage cylinder is connected with the fuel-displaced mechanism of Lever type, piston rod is hollow, is provided with the exhaust pull bar in the piston rod, and is gapped between exhaust pull bar and the piston rod.
Be provided with the exhaust pull bar in the piston rod, when loading butter in oil storage cylinder, can discharge by the gap of exhaust pull bar and piston rod because of air in the oil storage cylinder, oil storage cylinder can fill up, and improves utilization efficiency, and is fuel-displaced continuous.
As preferably, the fuel-displaced mechanism of Lever type comprises plunges pump body, the plunges pump body rear end is provided with the oil inlet hole that communicates with oil storage cylinder, the plunges pump body front end is provided with oil outlet, is provided with oil-feed cavity that holds the oil-feed plunger and the exhaust cavity that holds exhaust piston in the plunges pump body, and the exhaust cavity is provided with exhaust port, plunges pump body communicates with outside atmosphere by exhaust port, oil inlet hole communicates with the oil-feed cavity, and the oil-feed cavity communicates with the exhaust cavity, and oil outlet is located at the Connectivity Section of oil-feed cavity and exhaust cavity.
Two plunger cavitys are set in the plunges pump body, when the promotion piston rod is squeezed into plunges pump body with the butter in the oil storage cylinder, need not constantly to push drain tap, the air in the plunges pump body is discharged, simple to operate, good exhaust effect.
According to the technical solution of the utility model, be provided with the exhaust pull bar in the piston rod, when in oil storage cylinder, loading butter, can discharge by the gap of exhaust pull bar and piston rod because of air in the oil storage cylinder, oil storage cylinder can fill up, and improves utilization efficiency, and is fuel-displaced continuous.Two plunger cavitys are set in the plunges pump body, when the promotion piston rod is squeezed into plunges pump body with the butter in the oil storage cylinder, need not constantly to push drain tap, the air in the plunges pump body is discharged, simple to operate, good exhaust effect.
