Zusammenfassung: | FIELD: small arms. SUBSTANCE: salient feature of this trigger mechanism of pistol consists in that cock is manufactured with elements correspondingly for interaction with limiter of cock movement when bolt is closed incompletely and for its cocking to "cocked position and is installed in bolt on axle and firing spring is put into cock for interaction with its first end with limiter of spring expansion and with its second end with sear contacting in this case working surface of cock having two saw-toothed teeth correspondingly for modes "cocked position" and "safety position". Sear includes supporting element of cylindrical shape located in hole of bolt perpendicular to longitudinal plane of piston, lever put on supporting element for contact with template of sear made on frame and kinematically coupled to trigger and element made in the form of semi-cylinder attached with its butt to butt of supporting element and having supporting surface over cylindrical side along rib for interaction with proper tooth of cock along plane. Against this element of sear second end of fighting spring is pressed. Element to arm cock to mode "cocked position" is mounted for interaction with two conjugated guiding sections made in frame. First section is located at angle to longitudinal axis of barrel and is used to arm cock to mode "cocked position", second section is arranged in parallel to axis of barrel and is designed for provision of contact of sear with its supporting surface with corresponding tooth of cock. EFFECT: enhanced functional reliability of trigger mechanism. 2 cl
Изобретение относится к общему машиностроению, в частности к ударно-спусковым устройствам. Особенностью ударно-спускового устройства пистолета является то, что курок выполнен с элементами соответственно для взаимодействия с ограничителем перемещения курка при неполностью закрытом затворе и для взвода в режим "взведенное положение" и установлен в затворе на оси, а боевая пружина размещена внутри курка с возможностью взаимодействия первым своим концом с ограничителем хода пружины, а вторым концом - с шептало, контактирующим при этом с рабочей поверхностью курка, имеющей два пилообразных зуба соответственно для режимов "взведенное положение" и "предохранительное положение", а шептало имеет цилиндрической формы опорный элемент, расположенный в отверстии затвора перпендикулярно продольной плоскости пистолета, рычаг, закрепленный на опорном элементе с возможностью контактирования с копиром принудителя шеп |
