Abstract

Изобретение относится к конструкции складных ножей с запирающим механизмом типа "liner lock" и его разновидностей. Запирающий механизм складного ножа содержит клинок (2) с лезвием и пятой (1) на его замковой части с радиальным (3) и упорным (4) участками с проекциями на главном виде - AB и BC соответственно. Проекция BC упорного (4) и проекция AB радиального (3) участков образуют угол между ними, вершина которого обращена к клинку (2). Клинок (2) взаимодействует своей замковой частью с подпружиненной запирающей пластиной (6). Радиальный (3) и упорный (4) участки выполнены скошенными и одновременно взаимодействуют с торцом запирающей пластины (6), выполненным плоским с соответствующими участками (11) и (12). Смежный угол , образованный проекцией AB радиального участка (3) и линией, параллельной оси смещения O-O запирающей пластины (6), проходящей через вершину угла , является острым. Проекция торца запирающей пластины (6) и угол конгруэнтны. Изобретение позволяет повысить надежность складного ножа.The invention relates to the design of folding knives with a locking mechanism of the "liner lock" type and its varieties. The folding knife locking mechanism contains a blade (2) with a blade and a fifth (1) on its locking part with radial (3) and thrust (4) sections with projections on the main view - AB and BC, respectively. The projection BC of the thrust (4) and the projection AB of the radial (3) sections form an angle between them, the apex of which is facing the blade (2). The blade (2) interacts with its locking part with a spring-loaded locking plate (6). The radial (3) and thrust (4) sections are beveled and simultaneously interact with the end face of the locking plate (6), made flat with the corresponding sections (11) and (12). The adjacent angle formed by the projection AB of the radial section (3) and a line parallel to the axis of displacement O-O of the locking plate (6) passing through the apex of the angle is acute. The projection of the end face of the locking plate (6) and the angle are congruent. The invention improves the reliability of the folding knife.
