Description

Grease gun with inner tube

The utility model belongs to fueling vehicle.

Existing butter is swung, and does not have liner device, and butter is transported and stored at butter and swung tube, when adding butter, adds bit by bit, and speed is slow, and efficient is low, not only inconvenience but also unclean.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and a kind of butter of providing is transported and stored in inner bag, and after butter used, the butter that inner bag is arranged of replaceable inner bag was swung.

The purpose of this utility model can reach by following measure:

In the position that existing butter is swung the dress butter, the scalable inner bag of butter is equipped with in setting, outlet end and plunger accent that inner bag extrudes butter join, the inner bag the other end joins with the piston that is arranged in the Grease tube, the piston iron chains outer with stretching out Grease tube draws mutually, between peripheral piston of iron chains and bonnet spring is set, the iron chains import and export is provided with a bayonet socket in the bonnet central position, can block iron chains.

The relative prior art of the utility model has following advantage:

The utility model is that prior art is improved, and swings dress butter position at existing butter, and removable inner bag is set, and therefore, has one and is to use conveniently, and when the butter of inner bag used up, as long as change an inner bag, speed was fast; Two are to use the butter with liner device to swing, clean, sanitary; The 3rd, rational in infrastructure, make easily.

Accompanying drawing is the utility model structural drawing.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to accompanying drawing, the utility model is by packing ring (1,5,6), cushion rubber (2,9), swing bar (3), pipe joint nut (4), plug screw (7), butter is swung lid (8), butter is swung tube (10), inner bag (11), apron (12), piston (13), screw rod (14), spring (15,24), iron chains (16), iron hoop (17), bonnet (18), handle (19), plunger (20), pin (21), connecting rod (22), steel ball (23), bayonet socket (25) is formed, swing tube (10) one ends at butter and establish bonnet (18), the other end is established butter and is swung lid (8), and the external bar (3) of swinging, handle (19) is arranged at by connecting rod (22) and swings on the lid (8), at the middle part of bonnet (18) iron chains (16) is set, and be connected with piston (13), in iron chains (16) periphery, between piston (13) and bonnet (18) spring (15) is set, bayonet socket (25) is set at bonnet (18) iron chains (16) import and export.

During use, handle panel is moving, move behind the plunger, spring promotes the Piston Compression inner bag, and the butter of inner bag enters in the plunger cavity, and during the handle compression, plunger squeezes out butter to swing and chews.
