Abstract
The utility model discloses a leakage free type tool for the pressure injection of lubricant, which comprises an oil cup, a high-pressure knitting rubber hose and an oil gun. The utility model is characterized in that the utility model uses a 0 DEG to 90 DEG bend pipe as a connection pipe of a pressing nut connected with the high-pressure knitting rubber hose; a metal mesh of the high-pressure knitting rubber hose is a double-layer metal mesh; a piston in an oil pipe of the oil gun is provided with a chain for pulling the piston, an end cover of the oil pipe of the oil gun is provided with a hole and a transverse groove, and the piston, the hole and the transverse groove can be gradually locked when the chain is pulled. Compared with a tool for the pressure injection of lubricant, which is disclosed with the number of ZL93234113.6 of the Chinese patent, the utility model has better leakage-proof performance, and the oil injection pressure can be increased to 30MPa; air can not be brought into an oil storage barrel when lubricant is filled into the oil storage barrel, and the oil storage quantity is increased to 500 ml from original 400 ml. The utility model is particularly suitable for the grease filling of devices, such as large-sized and medium-sized motors of the Y series, rock drills, etc.
Description
Technical field
The utility model relates to a kind of nothing and leaks pressure injection lubricating grease instrument, and especially relating to a kind of Y of being specially adapted to series large and middle size motor and rock drill does not have the special tool that leaks the filling butter.
Background technique
The special tool lubricating cup and the grease gun of present widely used filling butter, because the oil inlet end of lubricating cup is that the pressured butter of tightly sealing leaks with connecting of high pressure hose, the pressure injection resistance is big, inconvenient operation, its oil gun gun barrel is interior owing to use the pull bar extension spring, therefore the piston central authorities in the gun barrel have tie rod hole, and butter leaks into the gun barrel back cavity by this hole easily, so that rifle lid outside; When the series of the Y in running large and middle size motor is annotated a large amount of butter, not only dangerous, and the phenomenon that pressure injection is not entered often appears, use rather inconvenience.China's utility model patent discloses a kind of modified model pressure injection lubricating grease instrument for ZL93234113.6 number, having overcome butter to a certain extent leaks easily, influence the defective of handling safety, but this butter pressure injection instrument oiling pressure is still less, it is desirable that reliability is still owed, bring air during the filling grease easily into, influence oil tube oil reserve.
The model utility content
The purpose of this utility model is to overcome existing lubricating grease pressure injection tool reliability and owes desirable defective, provides a kind of and can improve filling grease pressure, and the better nothing of anti-leak performance is leaked pressure injection lubricating grease instrument.
The defective of bringing air easily into when the further purpose of the utility model is to overcome existing lubricating grease pressure injection instrument filling grease provides a kind of nothing that can not bring air during grease into of annotating to leak pressure injection lubricating grease instrument.
The purpose of this utility model is achieved through the following technical solutions: it is to leak on the pressure injection lubricating grease instrument basis Chinese patent ZL93234113.6 number disclosed nothing to carry out improved a kind of technological scheme, it comprises lubricating cup, high pressure braiding rubber hose and oil gun, it is characterized in that, 0-90 ° of bend pipe (preferred version adopts 90 ° of bend pipes) selected in the connecting tube that weaves the gland nut of rubber hose connection with high pressure for use, can between lubricating cup and gland nut, not produce torsion when making refueling operation and become flexible, leakage of oil takes place owing to 90 ° of high-pressure metal net volume sebific duct bendings; The wire netting of high pressure braiding rubber hose changes bilayer into by individual layer, to improve the compression resistance of braiding rubber hose; Below be preferred version: 90 ° of bend pipes are selected in the connecting tube that weaves the gland nut of rubber hose connection with high pressure for use, and this more helps preventing the situation of leakage of oil; The outside thread of lubricating cup adopts M12 * 1, to improve intensity and tautness; Establish the chain of using for the pulling piston on the piston in the oil gun oil pipe, on oil gun oil pipe end cap, be provided with hole and transverse groove, so that can lock step by step during the pulling chain, thereby when making fatten, be convenient to gradation and add step by step, avoid whole tube oil once to add, make and bring air in the oil easily into.
With Chinese patent ZL93234113.6 number disclosed pressure injection lubricating grease instrument relatively, the utlity model has following advantage: operate easier, better reliability, the anti-leak performance is better, oiling pressure can be brought up to 30MPa; Can not bring air into when oiling refers in oil storage cylinder, oil reserve increases to 500ml by original 400ml.The utility model is specially adapted to equipment filling butter such as Y series large and middle size motor, rock drill.
