Abstract
The present invention relates to a grease injection nipple coupled to a grease pipe such that the same can function as an opening/closing valve with regard to the corresponding grease pipe, the grease injection nipple being pushed against a nipple of a grease supply target and coupled thereto or separated therefrom. The grease injection nipple according to the present invention comprises a push body, a check valve, a nipple coupling portion, and a valve activation portion. The valve activation portion may operate such that, when the push body makes a primary movement in the forward direction, the check valve is opened and, when the push body makes a secondary movement in the forward direction after external force for the primary movement of the push body is released, the check valve is closed.
Claims10
A grease injection nipple comprising:
- a push body including a first grease supply hole formed rearward and a second grease supply hole extending forward while communicating with the first grease supply hole and having an inner diameter smaller than an inner diameter of the first grease supply hole, in which an inside of the push body communicates with the second grease supply hole while being opened forward;
- a check valve pressed forward to close a connection part between the first grease supply hole and the second grease supply hole of the push body;
- a nipple coupling portion having a rear side inserted into the inside of the push body, and
- having a deployed structure configured to allow the nipple coupling portion to be inserted more into the inside of the push body when the push body moves forward in order to increase force for pressing an outer surface of a nipple of a grease supply target inserted into the inside of the push body;
- and
- a valve activation portion for opening the check valve when the push body primarily moves forward, and closing the check valve when the push body secondarily moves forward after releasing external force for enabling the push body to primarily move.
