The present invention relates to a manual grease injector, and more particularly, to a manual grease injector that can be detachably coupled to a handle having a C-shaped cross section to increase grip, prevent static electricity, and have an anti-slip function.

A conventional grease injector is shown in FIG. 4 is a US design patent publication Des. 407, 613, the handle 103 was formed by densely arranging the projection 103 on the outside of the main body 101 to which the grease is injected. It is formed integrally with the outer surface of the main body, it is formed of the same metal material as the main body.

However, such a grease injector is easy to slip the sweat of the operator's hands while holding the injector handle 102 and the main body 101, the metal is easy to heat transfer according to the ambient temperature and working temperature It can produce a grip temperature that is not suitable for the application.

Therefore, research on the handle which makes the grease injection operation easier and safer has been continued in the art.

The present invention is to solve the above problems, the handle is formed of a separate material from the main body of the grease injector and detachable to prevent the slip due to sweat or temperature during work and other factors. It is an object of the present invention to provide a manual grease injector which prevents static electricity and is not affected by ambient temperature.

As a construction means for achieving the above object, the present invention is a main body containing grease; Pumping means for discharging grease in the main body to the outside and having a coupling groove formed along a circumferential surface at a rear side thereof; And a C-shaped cross section, and having a coupling protrusion that is formed to protrude inward on the rear side and is coupled to the coupling groove, and a stopper portion protruding outward to prevent the hand from being pushed forward on the front side is formed. Provides a manual grease injector comprising a handle coupled to the rear side.

Preferably, the surface of the handle has a plurality of protrusions are formed repeatedly in the longitudinal direction of the main body to increase the grip, and the handle is detachable, preferably made of plastic.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a manual grease injector according to the present invention. In FIG. 1, a grease injector, commonly referred to as a grease gun, includes a main body 10 containing grease and a nozzle 15 through which grease is discharged on the front side of the main body. In addition, the grease in the main body 10 is discharged to the outside through the pumping means, the pumping means is discharged (not shown) mounted in the same manner as the piston therein, and discharged to the link coupling 14 with the discharge member The handle 13 will be included.

Figure 2 shows a handle that can be detachable to the body of the manual grease injector according to the present invention. The handle 20 is formed to have a C-shaped cross section as a whole, and when the part with the nozzle of the main body forward, the front side protrudes to the outer side to prevent the operator's hand from slipping from the handle portion to the main body 27 ) Is formed.

In addition, the inner side of the handle 20, the engaging projection 25 is formed along the circumferential inner surface of the handle. The rear side of the main body 10 is formed with a coupling groove to which the engaging projection 25 is coupled along the circumferential surface of the main body, and the engaging projection 25 is fitted into the engaging groove so that the position of the handle is engaged. Is determined.

In particular, since the handle 20 has a C-shaped shape with one side open, the handle 20 is detachable to the main body 10 by applying a slight force, so that the handle 20 is easily replaced according to damage to the handle and the user's environment. .

3 is a view illustrating a state in which the manual grease injector according to the present invention is actually used. The user holds the handle 20 in one hand and the other hand holds the grease discharge handle 13.

In addition, the handle 20 of the grease injector according to the present invention is repeatedly formed with a plurality of projections long in the longitudinal direction of the main body 10. This provides the effect of increasing the grip of the handle.

Using a detachable handle in this way, it is possible to prevent the sliding of the operator's hand slip by the leaked grease during work and to prevent the static electricity frequently generated in the low humidity environment of the winter. In addition, since the handle is formed of a plastic material that is different from the main body, grasping the metal body of the grease injector during the winter prevents the inconvenience of work due to the low temperature, and also prevents slippage due to sweat in the summer. There is an advantage.

While the present invention has been shown and described with respect to specific embodiments, it should be understood that the present invention may be variously modified and changed without departing from the spirit or the scope of the present invention provided by the following utility model registration claims. It will be appreciated that those skilled in the art can easily know.
