Claims

1. A grease injection device structure, comprising: a grease injection container, wherein a container screw-lock portion is provided on the upper outer side of one end of the grease injection container, the container screw-lock portion is recessed inward at the bottom to form a recessed groove, and the recessed groove extends outward at the bottom position to form a stop portion; A washer has an inner ring portion, a sleeve portion on the inner side of the center of the inner ring portion, an inner contact portion on one end face of the inner ring portion, and an outer ring portion extending outward from the inner ring portion, an outer contact portion on one end face of the outer ring portion, and a sticking portion on the opposite end face of the inner contact portion and the outer contact portion. The washer is fitted onto the recessed groove from the screw-lock portion of the container, the sleeve portion tightly surrounds the recessed groove, the inner contact portion is close to the end edge of the screw-lock portion of the container so that the inner ring portion is flush with the screw-lock portion of the container, and the sticking portion is tightly fitted onto the stop portion. A cover body has a cover body screw-locking part on the inner side of the center of one end of the cover body, and the cover body screw-locking part extends to the end edge to form a stop part. The cover body screw-locking part can be screwed together with the container screw-locking part, so that the cover body and the grease injection container are connected to each other.

2. The grease injection device structure as described in claim 1, wherein, The washer is an O-type elastomer.

3. The grease injection device structure as described in claim 1, wherein, This part is a flat surface.

4. The grease injection device structure as described in claim 1, wherein, The inner contact area is a flat surface.

5. The grease injection device structure as described in claim 1, wherein, The height of the outer ring is lower than that of the inner ring, so that the direction from the outer ring to the inner ring is two sections of different heights, like a staircase.

6. The grease injection device structure as described in claim 1, wherein, The outer contact area is a flat surface.

7. The grease injection device structure as described in claim 1, wherein, The part to be pasted is a flat surface.
