LOCKING PIN

摘要

Subject matter of the disclosure is a locking pin arrangement with a basic element for receiving an insert and a fall-proof locking pin for fixing the insert in the basic element. The locking pin is at least partially inserted into a borehole of the basic element and is pushed towards an opening of the borehole by a spring. The locking pin has a guiding surface for axial guidance in the borehole, an outer thread and a constriction positioned between the outer thread and the guiding surface, wherein the diameter of the outer thread is smaller than the diameter of the guiding surface and the diameter of the locking pin at the constriction is smaller than the diameter of the outer thread. Further, the arrangement comprises an inner thread going from the wall of the borehole into the space formed by the constriction.

1. Locking pin arrangement with a basic element for receiving an insert and a locking pin for fixing the insert in the basic element, wherein the locking pin is at least partially inserted into a borehole of the basic element and is pressed towards an insertion opening of the borehole by a spring positioned between a first end of the locking pin and a bearing surface of the borehole, a second end of the locking pin being shaped for fixing the insert,
wherein the locking pin has a guiding surface for axial guidance in the borehole, an outer thread and a constriction between the outer thread and the guiding surface, the outer thread being positioned between the first end of the locking pin and the constriction, the diameter of the outer thread is smaller than the diameter of the guiding surface and the diameter of the locking pin on the constriction is smaller than the diameter of the outer thread, and in that an inner thread matching the outer thread extends into the space formed by the constriction from the wall of the borehole.
