Description

Oil gun

Technical field

The utility model relates to oil gun, is used for the lubricated oiling of machinery equipment.

Background technique

Machinery equipments etc. are in operation, because mechanical wear needs topping-up lubricated, attach lubricant oil and use oil gun.The kind of oil gun is a lot, but existing oil gun structurally exists following defective: the one, and the oiling piston cylinder is opened on the opposite direction of spray boom nozzle, and piston cylinder bottom and oiling rod seal place are simple in structure, exist leakage of oil; The 2nd, the joint of spray boom and rifle body lacks sealing and locking, not only wants seepage, but also fractures easily, influences working life; The 3rd, there is not control structure between nozzle and the spray boom, oil dripping appears after the oiling, cause waste and pollution; The 4th, the control of suction port valveless can produce the bleed phenomenon; The 5th, suction pipe oral area depuration structure is not tight, and sucking unclean oil plant influences machine, causes by the infringement of oiling equipment.

Summary of the invention

The purpose of this utility model is in order to overcome the defective that prior art exists, to provide a kind of oiling piston cylinder to be subjected to the force intensity height, and pressure-resistant seal is good, spray boom is connected reliable, durable with the rifle body, anti-oil dripping device is installed on the nozzle, and suction port is bleed not, and the suction pipe oil strain is oil gun completely.

The technological scheme of the utility model oil gun is: the rifle body that a upper and lower segmentation is arranged, the epimere of rifle body is that gun barrel connects spray boom, the head of spray boom connects nozzle, the stage casing of rifle body is shaped on the oiling piston cylinder, piston and Returnning spring are installed in the oiling piston cylinder, the piston rod that connects piston matches with spanner, the hypomere of rifle body is a connecting cover, connecting cover links to each other with oil tank, suction pipe is installed in the oil tank, it is characterized in that the opening and the same direction of spray boom nozzle of oiling piston cylinder, plug screw is installed in opening, the bottom that Returnning spring is positioned at cylinder contacts with piston.

The same direction of the opening of oiling piston cylinder of the present utility model and nozzle, when pulling spanner compression piston bar and piston with hand, oil pressure is to the piston cylinder bottom, because the piston cylinder bottom is a blind hole, do not have leakage problem, as long as piston seal is good, oil just all outpours.In the opening that is not stressed, plug screw is installed, is prevented that the oil of bringing into from flowing out good seal performance from piston.Returnning spring is in the bottom of cylinder, and is easy for installation, and effect guarantees.In order to guarantee the piston reliability, the double sealing ring can be installed in piston.And, baffle ring and seal ring are arranged in the plug screw inboard in order further to improve the opening sealing.In order to improve being connected fastness and improving sealability of spray boom and rifle body, the head of spray boom is installed the two seals ring and insert in the gun barrel, fix by swivel nut in the joint of gun barrel and spray boom.In order to prevent that nozzle trapped fuel after oil spout from oozing, in the outlet of spray boom steel ball to be installed, and spring is arranged, steel ball and spring are outer to be fixed by nozzle.And at the joint of spray boom and nozzle installation seal ring and nut.In order to guarantee the air-breathing bleed that prevents again of oil tank, on the rifle body, be shaped on suction port, steel ball and spring composition one-way valve are installed in the suction port, and by screw.For guaranteeing the cleaning of oil, wire gauze filter is installed in the bottom of suction pipe.For improving the oil gun quality, its rifle body and oil tank are made by aluminum alloy material, and at tank bottom plastic bottom cover, the oil tank of damaging when preventing to fall are installed.

Specific implementation

The utility model discloses a kind of oil gun, have on one, the rifle body 19 of following segmentation (shell merogenesis), the epimere part of rifle body mainly is gun barrel (a fuel-displaced conveying pore), gun barrel connects spray boom 16, the head of spray boom connects nozzle 13, be shaped on nozzle opening 12 in the nozzle, be shaped on oiling piston cylinder 30 in the stage casing of rifle body, piston 22 and Returnning spring 5 are installed in the oiling piston cylinder, and the piston rod 9 that connects piston stretches out outside the cylinder and matches with spanner 8, and the hypomere of rifle body is a connecting cover 29, connecting cover links to each other with oil tank 4, so general gun barrel, oiling piston cylinder and connecting cover are as a whole, and oil tank is independent one, and suction pipe 3 is installed in the oil tank 4, major technology is characterised in that its opening of structure of oiling piston cylinder 30 and spray boom nozzle 13 are same directions, plug screw 31 is installed in opening, and baffle ring 6 and seal ring 7 are arranged as shown in Figure 1 left,, prevent that the oil leakage that piston brings from going out, the bottom that Returnning spring 5 is positioned at cylinder contacts with piston 22, so cylinder bottom is a blind pipe, and can leakage of oil.The oiling piston cylinder is through suction pipe 3 oil suction from oil tank 4, by check valve assembly in the perforate 24 oil is injected oil pipe again, then arrive spray boom 16, nozzle opening 12 from nozzle 13 sprays again, the power of piston relies on spanner 8 to promote piston rod 9, spanner 8 rotates around pin 20, and pin 20 is installed in the hook 21 on the rifle body.In order to guarantee the oiling effect, double sealing ring 23 is installed in the piston 22.In order to improve the reliability that spray boom connects, two seals ring 18 is installed and is inserted in the gun barrel at the head of spray boom 16, fix by swivel nut 17 in the joint of gun barrel and spray boom.At installation steel ball 10 of outlet of spray boom 16, and spring 11 is arranged, fix by nozzle 13 outside steel ball 10 and the spring 11.Tighten mutually with the joint installation seal ring 14 and the nut 15 of nozzle 13 at spray boom 16 again, guarantee that nozzle is oil-proof.Be shaped on suction port 28 on the rifle body, steel ball 26 be installed in the suction port and spring 27 is formed one-way valves, and fixing by screw 25, screw 25 has suction port, makes the suction port can be air-breathing but bleed not.Wire gauze filter 2 is installed in bottom at suction pipe 3, guarantees that oil plant sucks cleaning.Its rifle body 19 and oil tank 4 are made by aluminum alloy material, guarantee to have better mechanical strength.And,, can prevent the oil tank of damaging when oil tank falls as plastic bottom cover at the bottom of oil tank 4 installation bottom 1.
