ARTILLERY-TYPE WEAPON BREECHBLOCK MECHANISM Russian patent published in 2019 - IPC F41A3/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to artillery guns. Artillery bolt lock contains a breech, a wedge, spring-loaded ejectors, a wedge stop, levers, a yoke. Support installed in the breech slot is designed so that the fixation of the spring-loaded wedge stop in the open position occurs automatically after the shot when the wedge moves to the wedge open position. Removing the wedge from the stop occurs when the rod of the power cylinder is applied to the rocker arm, which transmits the force to the lever with the driver on the same axis as the stop. Position sensor is mounted on the cradle and operates when interacting with one of the arms of the two shoulders of the spring-loaded lever, the second arm of which through the hinge shelf interacts with the ejector.

EFFECT: elimination of premature closure of the shutter wedge when loading.
