Abstract

The present invention relates to a filling device of a manual grease gun that enables quick and easy filling of grease into the body of a manual grease gun without loss. The grease is filled in advance without filling grease into the inside of the manual grease gun. The present invention relates to a grease cartridge adapter capable of inserting a cartridge into a grease gun and allowing the cartridge to be mounted on a conventional manual grease gun at the same time for easy removal and replacement of the cartridge with the grease gun when the grease in the cartridge runs out.

Description

Manual grease gun grease adapter and grease cartridge for easy change of grease and prevent grease spills {Manual Grease Gun, grease catridge adapter and Grease cartridge for easy change grease cartridge, anti-leakage grease.}

Generally, when filling with grease in a manual grease gun, separate the grease gun head (Fig. 1) and grease gun barrel (Fig. 2) and insert the grease body into the grease in the grease container so Pulling the rod backward (FIG. 7) back moves the pressure rubber plate (FIG. 5) in the grease gun, and then fills the grease (FIG. 8) by the pressure difference. However, there was an inconvenience in filling and using the grease in the grease container and inconvenient to clean the grease because the grease gun body was contaminated with grease.

A grease inlet line consisting of a threaded grease outlet (Fig. 2) in the cartridge barrel (Fig. 7) and entering the grease extrusion cylinder (Fig. 4) of the grease gun head (Fig. 3). The cartridge (figure 2) by attaching the cartridge adapter (FIG. 6) to the section and assembling the cylindrical cartridge (FIG. 1) filled with grease in advance and the screw groove (FIG. 9) of the cartridge It is convenient to use because the cartridge (FIG. 1) can be easily removed from the grease gun body (FIG. 7) without spilling it to the grease body, and the grease gun head (FIG. 3) and cartridge A seal (FIG. 10) can be inserted between the adapter (FIG. 6) to prevent leakage of grease (FIG. 8) into the grease gun body (FIG. 7).

Figure 4 is a grease gun head and cartridge adapter assembly according to the present invention

The grease outlet (Fig. 2) of the grease cartridge body (Fig. 1) consists of threads and flows into the grease extrusion cylinder (Fig. 4) of the conventional grease gun head part (Fig. 3). Attach the cartridge adapter (FIG. 6) to the grease inlet conduit, and assemble the pre-greased cylindrical cartridge (FIG. 1) and the screw part of the cartridge adapter (FIG. 9) by threaded fastening. In addition, the configuration of the cartridge adapter by mounting the cartridge in the conventional grease gun head (FIG. 1) has the same structure as in FIG. 3, and the screw groove (FIG. 2) and the grease gun head that allow the assembly of the cartridge with the cartridge. And screw grooves (Fig. 3) for mounting and mounting are provided with screw grooves (Fig. 6) for filling grease from the outside of the grease gun head of Fig. 4 and fixing screws for the cartridge adapter. Fasten with bolts (Fig. 2) so that they can be fixed simultaneously with the holes (Fig. 3). Alternatively, it may be fixed by inserting a circular fixing pin (FIG. 5) in addition to the bolt. And the seal (Fig. 4) in the middle to prevent leakage to the grease gun body.

As described above, the cartridge mounting apparatus of the manual grease gun according to the present invention and the portable cartridge filled with grease have the following advantages.

When the cartridge mounted with the grease gun body is removed from the grease barrel, the cartridge extended by the grease gun internal pressure plate can be easily removed and there is no grease leak inside the grease gun body. Grease-filled grease drums or grease containers are not required to fill grease into the grease. Grease-filled cartridges are small in size and can be easily carried and stored. Can be.
