INTERMITTENT CANNON LOCKING APPARATUS PROVIDED WITH ROTARY CHAMBER OF ARTILLERY

摘要

The present invention relates to an intermittent locking/unlocking apparatus for a firearm including a rotary cartridge chamber that is intermittently rotated by 90 degrees in a housing to communicate with or interrupt from a barrel, which can fix the rotary cartridge chamber not to be deviated from a position aligned in a straight line with the barrel due to fire or external shock in a state in which the rotary cartridge chamber is arranged in a straight line with the barrel. The apparatus includes a locking groove formed on an outer surface of the rotary cartridge chamber, and a bracket provided on an outside of the housing. When a fixing lever is pivoted around a pivot pin provided on the bracket, a locking protrusion provided at an end of the fixing lever is selectively locked to or unlocked from the locking groove. A lever driving unit rotates the locking protrusion in forward and reverse directions to repeatedly lock or unlock the locking protrusion to or from the locking groove.
