Description
Technical field
The utility model relates to a kind of m of e instrument, particularly a kind of high pressure manual grease gun that is used for adding butter.
Background technique
Along with rapid economy development, the consumption that is used for adding the high pressure manual grease gun of butter constantly increases, but present high pressure manual grease gun in use has the following disadvantages, the one, the end face at headstock is opened in existing exhaust, outlet valve is housed, when after adding butter in the gun barrel, carrying out exhaust, on the exhaust port because butter is thicker, in the process of exhaust, will block exhaust outlet, cause being mixed with air in the butter, oil is arranged when causing refueling sometimes, do not have oil sometimes, block relief opening when serious, at all can't exhaust, so not only increase workload, reduce working efficiency, and can increase the wearing and tearing of plunger, reduction of service life; The 2nd, the stage clip of existing high pressure oil outlet is a volute spring, and an end withstands on the steel ball, and the other end is stuck on the screw thread, and after quick pressurization, steel ball is easy to eject; The 3rd, headstock is generally processed by aluminum alloy or zinc alloy, poor rigidity, plunger in the course of the work, plunger hole is easy to wearing and tearing, causes grease gun to damage, working life is short; The 4th, because spring directly promotes piston ring, and piston ring is generally made by rubber, and the piston ring discontinuity causes piston ring distortion leakage of oil; The 5th, because whole oiling gun barrel made Heavy Weight, cost height by iron, zinc alloy or aluminum alloy.For this reason, many manufacturers and knowledgeable people have carried out R and D, but do not have rational product to emerge so far as yet.
Summary of the invention
At existing high pressure manual grease gun above shortcomings, the purpose of this utility model provides a kind of simple and reasonable, reliable operation, use is light, the life-span is long high pressure manual grease gun.
The technological scheme that its technical problem that solves the utility model adopts, it comprises gun barrel, headstock, handle, pull bar, spring, the rubber piston circle, handle, plunger, link, gun barrel is fixed on the headstock, be arranged on behind the sheathed spring of pull bar in the gun barrel and and fix with the rubber piston circle, pull bar one end stretches out gun barrel and is connected with handle, plunger is arranged on the plunger hole of headstock, one end and the handle of plunger are hinged, link one end is hinged on the headstock, the other end is hinged on the handle, described headstock is provided with air vent, and gun barrel is provided with the seal ring that cooperates with the headstock end face.
The plunger hole outlet of described headstock is equipped with steel ball, stage clip and high pressure joint successively.
Be inlaid with the steel bushing that is complementary with plunger on the plunger hole of described headstock.
Between spring and rubber piston circle, be provided with spring collar.
Be fixed with taper knob on the described handle.
Described gun barrel and headstock are made of plastics.
After adopting said structure, the utility model compared with prior art has following advantage: the one, changed exhaust mode, and from the air vent exhaust of headstock, only need gun barrel and headstock are unclamped half-turn, leave just exhaust of gap between cooperation of headstock end face and the seal ring but make, just tighten and to work; The 2nd, stage clip changes straight spring into, fixedly high pressure joint of outlet, and after the pressurization, steel ball can not extruded yet fast; The 3rd, plunger hole is inlayed steel bushing, has improved wear-resisting property, and plunger work is more reliable, long service life; The 4th, spring collar has not only strengthened the intensity of rubber piston circle, and makes the rubber piston circle stressed evenly, can not produce the distortion leakage of oil; The 5th, owing to gun barrel, headstock are made of plastics, cost is low, in light weight, uses light.
