Abstract

The utility model belongs to the technical field of a grease filling tool, particularly the improvement of a grease gun in a chain pressure spring type. The utility model is composed of a gun head, a gun body, a handle, a large spring, a chain, a grease bowl, a skeleton, and a high pressure hose. The utility model is characterized in that the gun head is provided with a plunger piston hole in which a plunger piston is matched and arranged; an annular slot is arranged on the plunger piston, and a sealing ring is arranged in the annular slot; both sides of the lower end of the plunger piston hole of the gun head are respectively provided with a grease inlet hole and a grease outlet hole, and one way valves are respectively arranged on the grease inlet hole and the grease outlet hole; a chain mechanism is arranged in the gun body. The utility model has the advantages of large grease supplying pressure, difficult generation of a hollow cavity, time saving, compact structure, and reduced manufacture cost.

Description

Two-way hydraulic control injection grease gun

The utility model belongs to the oiling technical field of tools, specifically relates to a kind of improvement to chain pressure spring type grease gun.

At present, at the widely used grease gun in fields such as machinery pressure bar type and piston chain compression type two big classes are arranged; Wherein press bar type grease gun is divided into hard tube formula and hose type grease gun, and the shortcoming of press bar type grease gun is that the push rod exposed portions serve is longer, has increased volume and parking space, and pressure is little, simultaneously the lubricating grease operator that makes dirty easily; The utility model patent (ZL96 2 30279.1) of on November 4th, 1998 bulletin discloses a kind of piston chain compression type grease gun, the problems referred to above are overcome to some extent, but still there is underpressure in this kind grease gun, refuels slow-footed deficiency.

The purpose of this utility model is to provide a kind of oiling pressure abundance, refuels fireballing two-way hydraulic control injection grease gun.

The technical solution of the utility model is achieved in that the improvement to existing piston chain compression type grease gun, formed by rifle head, rifle body, handgrip, big spring, chain, oil bowl, skeleton and high pressure hose, be characterized in having plunger hole, in plunger hole, cooperate plunger is installed at described rifle head, on plunger, have circular groove, seal ring is housed in circular groove; Both sides, plunger hole lower end at the rifle head respectively have oil inlet hole and oil outlet, at oil inlet hole and oil outlet place steel ball and steel ball are housed respectively, are pressed with little spring on steel ball; Have two filler openings at the oil inlet hole place, these two filler openings and oil outlet communicate with the bottom of plunger hole; Having internal thread at an end of rifle head matches with the outside thread of rifle body upper end and is connected.Handgrip is by pin, pin and connecting rod and plunger flexible connection, and protruding on the connecting rod the other end and the rifle head is connected with pin; High pressure hose is connected with oil outlet on the rifle head by screw thread.Oil bowl and skeleton are installed in the rifle body, and the opposite side of rifle body is stamped bonnet, and by the dowel fixes at pin rod two ends, pin rod is connected with the outer bracelet of chain and bonnet in oil bowl and the skeleton.In the rifle body, between skeleton and bonnet, big spring is housed.

Steel ball and steel ball play the one-way valve effect.

Use the utility model to have the oil mass supply pressure big, thereby overcome dry lubrication fat viscosity height, the shortcoming of mobile difference, make lubricating grease can successfully be filled to needed position, be difficult for simultaneously producing the hole, save time, also have compact structure simultaneously, reduce the good effect of manufacture cost.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the enlarged diagram of rifle head of the present utility model;

Further narrate the utility model below in conjunction with drawings and Examples:

Formed by rifle head 20, rifle body 8, handgrip 6, big spring 7, chain 22, oil bowl 4, skeleton 5 and high pressure hose 17, be characterized in having plunger hole 23, in plunger hole 23, cooperate plunger 3 is installed at described rifle head 20, on plunger 3, have circular groove, seal ring 19 is housed in circular groove; The effect of seal ring 19 is to go here and there on the lubricating grease that prevents in the plunger hole 23; Both sides, plunger hole 23 lower end at rifle head 2 respectively have oil inlet hole 12 and oil outlet, at oil inlet hole 12 and oil outlet place steel ball 13 and steel ball 14 are housed respectively, and steel ball 13 and steel ball 14 play the one-way valve effect.On steel ball 14, be pressed with little spring 15; Have two filler openings at the oil inlet hole place, these two filler openings communicate with the bottom of oil outlet with plunger hole 23; Having internal thread at an end of rifle head 20 matches with the outside thread of rifle body 8 upper ends and is connected.Handgrip 6 flexibly connects with connecting rod 21 and plunger 3 by pin 1, pin 2, and protruding on the other end of connecting rod 21 and the rifle head 20 is connected with pin; High pressure hose 17 is connected with oil outlet on the rifle head by screw thread.Oil bowl 4 and skeleton 5 are installed in rifle body 8, and the opposite side of rifle body 8 is stamped bonnet 9, by the dowel fixes at pin rod two ends, 5 times pad 11 is housed at skeleton in oil bowl 4 and the skeleton 5, and pin rod is connected with bracelet 10 outside the bonnet 9 with chain.In rifle body 8, between skeleton 5 and bonnet 9, big spring 7 is housed.

The utility model is work like this, screw off rifle head 20, tension bracelet 10, oil bowl 4 and skeleton 5 compression big springs 7, oil bowl 4 is pulled to the bottommost of rifle body 8, lubricating grease is loaded in the space of rifle body body 8, after lubricating grease is filled, screw on rifle head 20, unclamp bracelet 10, lubricating grease is under pressure under the effect of big spring 7; Pull-up handgrip 6, plunger 3 is pulled up, and steel loop 13 is opened oil inlet hole under the effect of the suction of plunger and the lubricating grease that is subjected to big spring 7 pressure, and lubricating grease is filled in plunger hole 23 chambeies in the rifle head 20 by two filler openings, for several times, can be full of repeatedly.When the needs grease up, depress handgrip 6, the plunger 3 descending steel loops 14 of washing open are compressed little spring 15, and lubricating grease enters in the high pressure hose 17; When pull-up handgrip 6, plunger 3 is up, and steel ball 14 is closed oil outlet under the effect of spring 15, and simultaneously steel ball 13 is opened oil inlet hole, and the lubricating grease in the rifle body 8 are added to again in plunger hole 23 chambeies in the rifle head 20.Because the effect repeatedly of plunger 3 can produce high-pressure grease.
