Abstract
The utility model provides a pressurizing type grease gun with an outer sleeve barrel. A grease device of the utility model is composed of a grease stopper, a grease cylinder, a one way valve, a grease filling mouth, and a pressing handle. A grease storing device is composed of a grease gun barrel, a piston, and an energy storing spring, the outer sleeve barrel which can be adjusted in axial positioning is hung on and connected with a clamping post on the outer wall of the grease gun barrel, and the energy storing spring is arranged in the outer sleeve barrel and on the back of the piston. The utility model has the advantages of simpleness, reasonability, low production cost, convenient operation, large capacity, and good sealing performance, and in addition, the outer sleeve barrel can be separately arranged. The piston is pressed and is pressurized through the outer sleeve barrel via the energy storing spring, grease and air in the grease gun barrel can be simultaneously exhausted, and the greases in the grease gun barrel can be guaranteed to be completely used up.
Description
The utility model belongs to oil-filling device, relates in particular to a kind of outer sleeve pressured type grease gun.
For giving mechanical friction parts filling lubricant oil, the most frequently used grease gun is dimerous by oiling device and Fuel Tanking Unit.During oiling, hand pressure handle, oil filler plug with the grease in the oil cylinder through one-way valve, inject the lubricant housings by pump nozzle, lift the device pressure handle, one-way valve blocks the route of retreat of grease, make oil cylinder produce negative pressure, the grease in the oil barrel is filled and is mended in the oil cylinder under the effect of piston and energy storage spring.Repeating motion like this just can constantly be carried out oiling.Though this kind grease gun is comparatively simple, can very inconvenient when filling butter in the oil barrel.At first must unload oil barrel from oiling device, the piston pulling rod of pulling in the oil barrel makes piston fall back on the rear portion of oil barrel, and fixes by insurance card, fills butter again in oil barrel.Because this moment, the pressure of piston rear portion energy storage spring was very big, be easy to after insurance card is vibrated throw off, and piston is rebounded, thereby with the ejection of turning out in full force of the butter in the oil barrel.This not only causes waste, has also caused environmental pollution.Make simultaneously the operator often both hands stick greasy dirt, be easy to infiltrate sand grains or fiber in the grease, cause and stop up and oiling is interrupted.Owing to be provided with piston pulling rod, so the sealability of piston is relatively poor, the grease seepage is serious, and oil gun is often soaked by oil stain.In addition, because grease and energy storage spring are all in same oil barrel, so the capacity of grease is very limited, equally, also because of being subjected to the restriction in space, pressure is limited for the energy storage spring at rear portion, along with the continuous discharge of grease, the pressure of spring weakens gradually, so that during remaining at last a small amount of grease, just do not have enough pressure that it is clamp-oned in the oil cylinder, have to interrupt oiling.
The purpose of this utility model is to provide a kind of capacity big, and filling grease facility can make the outer sleeve pressured type grease gun of energy storage spring supercharging.
The utility model is achieved in that this grease gun comprises oiling device and Fuel Tanking Unit, oiling device is made up of oil filler plug, oil cylinder, one-way valve, pump nozzle and pressure handle, Fuel Tanking Unit is made up of oil barrel, piston and energy storage spring, described oil barrel also is provided with an outer sleeve outward, outer sleeve is enclosed within outside the oil barrel, and can do the axially locating adjustment, and energy storage spring is positioned in the outer sleeve, the one end is pressed in the bottom of outer sleeve, and the other end is pressed on the piston.
The utility model respectively is provided with a card post on the relative position in the middle of the oil barrel outer wall both sides, and the front end of sleeve wall outside and has a pair of slot on two corresponding positions of card post vertically, has several grabs in a side of slot; The bottom of described outer sleeve has center hole, and has a circle inner edge; Described piston can be manufactured with plastics or synthetic resin, has groove on the periphery of piston, studs with a circle oil-resistant rubber ring on the groove, is provided with the contact of an energy coupling link rope in the central position at piston back; The length of described energy storage spring is bigger than traditional; On the inwall of outer sleeve, be coated with plastic pellicle.
The utility model outer sleeve pressured type grease gun is simple in structure, reasonable in design, cheap, easy to operate, cleaning, capacity is big, good seal performance, grease utilization ratio height, can reach 100%, adopt by outer sleeve through energy storage spring to piston exert pressure, the mode of supercharging, oil, gas in the oil barrel are discharged simultaneously, and guarantee that the grease in the oil barrel uses up fully, not the time spent, can take outer sleeve, both separate placement.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the structural representation of the utility model outer sleeve pressured type grease gun.
Can see that from accompanying drawing the front half part of the utility model outer sleeve pressured type grease gun also is that oiling device is mainly combined in the usual way by oil filler plug 5, oil cylinder 4, one-way valve 3, pump nozzle 2 and pressure handle 1.Its latter half part also is that Fuel Tanking Unit mainly is made up of oil barrel 6, piston 10, energy storage spring 11 and outer sleeve 9.The front end of oil barrel 6 links by screw thread and oiling device, respectively is provided with a card post 7 on middle relative position, oil barrel 6 outer wall both sides.At the front end of outer sleeve 9 barrels, and have a pair of slot vertically on two card posts, the 7 corresponding positions, have several grabs 8 in a side of slot, energy storage spring 11 is positioned in the outer sleeve 9.During use, the slot of outer sleeve 9 is facing to card post 7, by after be enclosed within the outer surface of oil barrel 6 forward, locate by the cooperation of card post 7 and grab 8.One end of energy storage spring 11 withstands on the bottom of outer sleeve 9, and the other end withstands on the piston 10, and piston 10 is positioned in the oil barrel 6.Because the energy storage spring 11 that is positioned in the outer sleeve 9 is not subjected to the restriction in an interior space, can suitably increase its size, to increase elastic force.Piston 10 described in the utility model can adopt plastics or synthetic resin to manufacture, and has the better seal effect for making piston 10, is provided with groove on its periphery, is inlaid with a circle oil-resistant rubber ring 12 on groove.Descending for be convenient to drag piston 10 before filling grease, the central position that is preferably in piston 10 back sides is provided with the contact of an energy coupling link rope.For ease of energy storage spring 11 location, be preferably in corresponding position, piston 10 back sides and have a circle groove, have center hole in the bottom of outer sleeve 9, and have a circle inner edge 13, the chain rope that connects piston 10 can be derived in center hole.Grab 8 on the outer sleeve 9 is offered three as required and is advisable, during use, can be according to what of greases in the oil barrel 6, adjust the axial position of energy storage spring 11 by the displacement of outer sleeve 9, to guarantee that energy storage spring 11 has enough pressure to act on piston 10 all the time.For reducing surface friction drag, can on the inwall of outer sleeve 9, spray layer of plastic film.The utility model outer sleeve pressured type grease gun is the time spent not, outer sleeve 9 can be backed off, and separates placement with the rifle body.
