Abstract

The utility model discloses a clean type grease gun, composed of a plunger pump, a cylinder body, and a pressing accessary device. The utility model is characterized in that the internal of the cylinder body is additionally provided with a crumpling type grease packing tank so that a pump body and the grease packing tank form complete grease supplying integration. The utility model has the advantages that the structure is simple and the use is safe and convenient. The utility model both effectively solves the problem that the grease is unclean when the grease gun is filled with the grease, and effectively prevents the pollution of the clothing of users by the grease.

Description

The clean type grease gun

The utility model relates to a kind of mechanical lubrication instrument.

Existing grease gun mainly is made up of plunger pump and cylindrical shell two large divisions.During use, butter fat is poured in the cylindrical shell by hand, the pressing handle drives plunger butter fat is injected mechanical lubricating component then.The disadvantage of this grease gun is: butter filling extremely bothers, not only pollute user's clothing easily, and careless slightlyly just dirt or sand might be brought in the butter, the lighter stops up the oil outlet of grease gun, weight person injects mechanical lubricating component with sand with butter, can cause serious mechanical accident.

In view of the problem of above-mentioned existence, the purpose of this utility model provides that a kind of can butter is convenient, safe in utilization, the clean type grease gun of health.

For achieving the above object, the utility model has been taked following technical measures:

The utility model has added a butter packing jar in the cylindrical shell of grease gun, butter packing jar is a folding structure.The pump housing and butter packing jar complete butter fuel feeding integral body of common formation.During use, the butter packing jar of filling butter is installed in the filler opening place of the plunger pump in the cylindrical shell.Like this, not only solved the unclean problem of butter that grease gun may occur effectively when the can butter, and prevented the pollution of butter effectively user's clothing.

Concrete structure of the present utility model as shown in drawings, wherein:

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

Fig. 2-Fig. 4 is respectively a butter packing jar and the structural representation of pump housing joint

Fig. 5 is the schematic cross-section at the oil outlet place shown in Fig. 2

Fig. 6 is the schematic cross-section at the oil outlet place shown in Fig. 3

Fig. 7 is the schematic cross-section at the oil outlet place shown in Fig. 4

For ease of understanding the utility model, be elaborated below in conjunction with the embodiment who provides in the accompanying drawing:

The clean type grease gun includes parts such as plunger pump 1, cylindrical shell 3 and pressing aid device 4.Plunger pump 1 is made of the pump housing 7, oil outlet 5, one-way valve 6, plunger 9 and pull bar 8 and handle 12.In cylindrical shell 3, be provided with butter packing jar 2.Butter packing jar 2 is the tube structure of a folding.On the pump housing 7, be provided with filler opening 11 and oil input channel 10, filler opening 11 is the tubular axis setting.Butter packing jar 2 is installed in filler opening 11 places of the plunger pump in the cylindrical shell 3.The oil outlet 18 of butter packing jar 2 and filler opening 11 phase configuration on the pump housing.It can be a worm structure or for outlet structure or for bayonet arrangement.For bayonet arrangement, at the bayonet socket place, be provided with elastic bayonet lock 17.Butter packing jar 2 can adopt plastic production, is the one-time consumption product.

The pressing aid device 4 of clean type grease gun is arranged at the bottom that the butter in the cylindrical shell 3 is packed jar 2.Pressing aid device 4 contains a top cap 13.In top cap 13, be provided with spring 14 and slide fastener 16.Be provided with bonnet 15 in the bottom of cylindrical shell.

Working method of the present utility model is achieved like this:

During use, the butter jar 2 that will fill butter earlier is installed in filler opening 11 places of Plunger pump body, with pulling moving slide fastener 16 pressure springs 14, loads onto cylindrical shell 3 then, makes 13 pairs of butter packings of top cap jar 2 that compression be arranged.At this moment, pressing handle 12, under the effect of plunger 9, butter packing jar 2 interior butter can be discharged from oil outlet 5 by filler opening 11, the oil duct 10 on the pump housing 7, and required lubricated mechanical component is lubricated.
