Abstract
The utility model discloses a grease gun, which comprises a gun head, a gun breech, a plunger pump handle and a connecting device used for connecting the gun head and the gun breech, wherein the gun head is provided with grease pumping devices, nozzle tips, nozzle tip check valves and grease inlet connectors spliced with the oil outlet of a grease cylinder; the gun breech is provided with a piston pneumatic propulsion device of the grease cylinder; and the grease pumping devices are two plunger pumps which are oppositely arranged along the same axis grease discharge outlet. The grease gun has high grease pumping output in unit time and high working efficiency.
Description
Technical field
The utility model relates to a kind of grease compressor for machine or equipment lubrication, especially a kind of grease gun.
Background technique
A kind of common tool of maintaining machinery of grease gun, at present, the grease gun of selling on the market mostly is manual filling when loading butter in grease gun, time-consuming, effort and unhygienic, CN101555981 discloses the novel grease gun of a kind of charge of oil fast, this grease gun uses the good Grease tube of can in advance, adopt the mode of changing Grease tube to realize in grease gun, loading butter, adopt pressurized air to promote the interior piston advances forward of Grease tube, realization is to the plunger pump fuel feeding of rifle head, but this grease gun in use, is the oil suction stroke when having removed the plunger pump handle, be the oiling stroke during depression of plunger pump handle, therefore, only in the oiling stroke, there is butter to pump from gun adapter, cause interior oil pump capacity of unit time few, can not realize the butter of annotating fast, inefficiency.
The model utility content
The technical problem that model utility will solve: a kind of grease gun is provided, and the pump oil mass is big in this grease gun unit time, high working efficiency.
The technological scheme that the technical solution problem is taked: a kind of grease gun, comprise rifle head, gun breech, plunger pump handle and be used to connect the connection set of rifle head and gun breech, the oil-feed interface that on described rifle head, is provided with oil pumping device, oil nozzle, oil nozzle one-way valve, pegs graft with the Grease tube oil outlet, be provided with Grease tube piston pneumatic propelling unit at gun breech, described oil pumping device is two plunger pumps that are oppositely arranged along same axis oil drain out.
As improvement of the present utility model: be provided with T type one-way valve at the oil drain out of two plunger pumps and the intersection of oil nozzle.
As further improvement of the utility model: the plunger of one of them plunger pump and plunger pump handle are hinged, and the plunger of another plunger pump is hinged by connecting rod and plunger pump handle, and the moving direction of two plungers is opposite during the action of plunger pump handle.
Further improve again as of the present utility model: the filler opening of two plunger pumps by two independently in line check valve be connected with shoe cream room.
Improve as another kind of the present utility model: in line check valve, be provided with the spacing thimble that anti-on-slip ball stops up oil outlet.
Rotatable locking card is set on connection set, the draw-in groove that matches with the locking card is set on connecting rod.
Beneficial effect: in the utility model, owing to adopted the oil pumping device of two plunger pumps that are oppositely arranged along same axis oil drain out as grease gun, make this grease gun in the more common grease gun unit time that a plunger pump only arranged the pump oil mass big, high working efficiency; Owing to adopted the plunger of one of them plunger pump and plunger pump handle hinged, the plunger of another plunger pump is hinged by connecting rod and plunger pump handle, opposite this technical characteristics of the moving direction of two plungers during the action of plunger pump handle, make grease gun of the present utility model drive two plunger pump work by a plunger pump handle handle motion, all there is butter to pump when the plunger pump handle has been removed or depressed, further improved working efficiency; Owing to be provided with T type one-way valve at the oil drain out of two plunger pumps and the intersection of oil nozzle, can prevent the phase mutual interference when two plunger pumps are worked, the fuel-displaced continuity of oil nozzle is good when making the oiling of this grease gun, stable working state; Since the filler opening of two plunger pumps by two independently in line check valve be connected with shoe cream room, further reduced the phase mutual interference when two plunger pumps are worked, and when a plunger pump breaks down, do not influenced another plunger pump work; Owing in line check valve, be provided with the spacing thimble that anti-on-slip ball stops up oil outlet, make the plunger pump oil-feed resistance of this grease gun little, the oiling operation is more laborsaving; Because rotatable locking card is set on connection set, on connecting rod, be provided with locking and block the draw-in groove that matches, therefore, grease gun carry connecting rod in the process, plunger, plunger pump handle relative fixed, avoid that butter pumps from oil nozzle in the process of carrying.
Description of drawings
Fig. 1 is a grease gun structural representation of the present utility model;
Embodiment
Fig. 1 shows agent structure of the present utility model, a kind of grease gun, comprise rifle head 3, gun breech 16, plunger pump handle 15 and be used to connect the connection set 14 of rifle head 3 and gun breech 16, on described rifle head, be provided with oil pumping device, oil nozzle 1, oil nozzle one-way valve 2, oil-feed interface 13 with the grafting of Grease tube oil outlet, be provided with Grease tube piston pneumatic propelling unit at gun breech 16, described oil pumping device is two plunger pumps 5 that are oppositely arranged along same axis oil drain out, the plunger of one of them plunger pump and plunger pump handle 15 are hinged, the plunger 6 of another plunger pump is hinged by connecting rod 7 and plunger pump handle 15, the moving direction of two plungers is opposite when the plunger pump handle moves, the filler opening of two plunger pumps by two independently in line check valve 11 be connected with shoe cream room 12, in in line check valve 11, be provided with the spacing thimble 10 that anti-on-slip ball stops up oil outlet, be provided with T type one-way valve 4 at the oil drain out of two plunger pumps and the intersection of oil nozzle.In order to prevent that oil gun plunger pump handle displacement in the process of carrying from causing butter to pump from oil nozzle, rotatable locking card 9 is set on connection set 14, on connecting rod 7, be provided with simultaneously and locking card 9 draw-in grooves that match 8, like this when locking card 9 has been removed lock with draw-in groove 8 after, limited the displacement of connecting rod and plunger, therefore, plunger pump handle position can displacement yet in the process of carrying.
