Description

МЕХАНИЗМ ЗАПИРАНИЯ LOCKING MECHANISM
Область техники, к которой относится изобретение. Изобретение относится к стрелковому оружию, в частности к механизмам запирания.The technical field to which the invention relates. The invention relates to small arms, in particular to locking mechanisms.
Предшествующий уровень техники.The prior art.
Известен запирающий механизм винтовок [1] запирание которого осуществляется при помощи затвора, детали которого, входя во взаимо- действие с соответствующими опорными плоскостями ствольной коробки, производят непосредственное запирание канала ствола. Ствольные коробки являются связующим всех основных частей и механизмов винтовки.The locking mechanism of rifles [1] is known, which is locked using a bolt, the details of which, when interacting with the corresponding reference planes of the receiver, directly lock the barrel. Receivers are the binder of all the main parts and mechanisms of the rifle.
Механизмы такого типа, они имеют продольный канал в ствольной коробке или направляющие для движения затвора или затворной рамы. Недостатками известных устройств является большие габариты самого механизма, технологическая сложность изготовления ствольной коробки, а также неточность согласования затвора со стволом, в связи с накоплением отклонений в цепочке технологических допусков (например: ствол — ствольная коробка - направляющие - затворная рама - затвор). Известно более компактное техническое решение "UZI" (пистолет- пулемет) [2] в котором применен набегающий на ствол затвор. Затвор выполнен в форме прямоугольного бруса, который имеет направляющие выступы по бокам для движения в ствольной коробке. Недостатками известных устройств является технологическая сложность изготовления ствольной коробки, неточность согласования затвора со стволом.Mechanisms of this type, they have a longitudinal channel in the receiver or guides for the movement of the shutter or bolt frame. The disadvantages of the known devices are the large dimensions of the mechanism itself, the technological complexity of the manufacture of the receiver, as well as the inaccuracy of matching the shutter with the barrel, due to the accumulation of deviations in the technological tolerance chain (for example: barrel - receiver - guides - shutter frame - shutter). A more compact technical solution "UZI" (submachine gun) [2] is known in which a bolt running on the barrel is used. The shutter is made in the form of a rectangular beam, which has guide tabs on the sides for movement in the receiver. The disadvantages of the known devices are the technological complexity of manufacturing the receiver, the inaccuracy of matching the shutter with the barrel.
Последнее техническое решение является наиболее близким по технической сущности и поэтому принято в качестве прототипа. Технической задачей изобретения является уменьшение габаритных размеров затвора, увеличение точности согласования затвора и канала ствола (следовательно, и точности стрельбы), упрощение конструкции оружия.The last technical solution is the closest in technical essence and therefore adopted as a prototype. An object of the invention is to reduce the overall dimensions of the bolt, increase the accuracy of matching the bolt and the bore (hence, accuracy of shooting), simplify the design of weapons.
Раскрытие сущности изобретения. Поставленная техническая задача достигается тем, что в предлагаемой конструкции затвор имеет внутренний канал. Внутренняя поверхность канала затвора является направляющей для движения по наружной поверхности ствола. Затвор также может иметь опорные поверхности для запирания. Наружная поверхность ствола является направляющей для затво- ра и также может иметь опорные поверхности для запирания.Disclosure of the invention. The stated technical problem is achieved by the fact that in the proposed design the shutter has an internal channel. The inner surface of the bore channel is a guide for movement on the outer surface of the barrel. The shutter may also have supporting surfaces for locking. The outer surface of the barrel is a guide for the shutter and may also have supporting surfaces for locking.
Новым в предлагаемом затворном механизме является то, что позиционирование затвора при запирании производится непосредственно по стволу.New in the proposed shutter mechanism is that the positioning of the shutter when locking is made directly along the barrel.
Приведенные отличительные особенности заявляемого изобретения в сравнении с прототипом позволяют уменьшить габариты устройства, увеличить точность позиционирования затвора относительно ствола, за счет исключения из технологической цепочки допусков ряда деталей (ствольная коробка, затворная рама, направляющие и т.п.). Изобретение поясняется чертежами. ОThese distinctive features of the claimed invention in comparison with the prototype can reduce the dimensions of the device, increase the accuracy of the positioning of the shutter relative to the barrel, due to the exclusion from the process chain of tolerances of a number of parts (receiver, shutter frame, guides, etc.). The invention is illustrated by drawings. ABOUT

Вариант осуществления изобретения.An embodiment of the invention.
Механизм запирания (Фиг. 1.) содержит ствол 1 и затвор 2 набегающий на ствол 1. Корпус затвора имеет внутренний направляющий канал, позиционирование затвора и канала ствола при запирании, осуществляется взаимодействием внутренней поверхности затвора и наружной поверхности ствола.The locking mechanism (Fig. 1.) comprises a barrel 1 and a shutter 2 running on the barrel 1. The shutter body has an internal guide channel, the shutter and the bore are positioned when locking, by the interaction of the inner surface of the shutter and the outer surface of the barrel.
Затворный механизм работает следующим образом. Исходное положение: затвор 2 открыт (находится в крайнем заднем положении). При помощи любого известного устройства (например, руко- ятки перезаряжания) затвор перемещается в сторону ствола, толкая перед собой патрон 3. Патрон 3 попадает в ствол 1. Внутренняя поверхность затвора 2 входит в соприкосновение с наружной поверхностью ствола 1 и, позиционируясь только по ней, двигается до упора. Зеркало затвора 2, воздействуя на дно гильзы, досылает патрон 3 в ствол 1, одновременно пози- ционируя его строго по оси ствола 1. На позиционирование патрона 3 относительно ствола 1 влияет только допуск между стволом 1 и затвором 2, и перпендикулярность зеркала затвора 2, относительно оси затвора 2. Отпирание затвора - в обратном порядке. Таким образом, допуски остальных соединений и направляющих на позиционирование затвора и ствола влияние не оказывают. Уменьшены габариты затвора, увеличена точность.The shutter mechanism operates as follows. Starting position: shutter 2 is open (located in the extreme rear position). Using any known device (for example, reloading handles), the bolt moves towards the barrel, pushing the cartridge 3 in front of it. The cartridge 3 enters the barrel 1. The inner surface of the bolt 2 comes into contact with the outer surface of the barrel 1 and is positioned only along it moves to the stop. The mirror of the shutter 2, acting on the bottom of the liner, sends the cartridge 3 into the barrel 1, at the same time positioning it strictly along the axis of the barrel 1. Only the tolerance between the barrel 1 and the shutter 2 affects the positioning of the cartridge 3 relative to the barrel 1, and the perpendicularity of the shutter mirror 2, relative to the axis of the shutter 2. Unlocking the shutter - in the reverse order. Thus, the tolerances of the remaining joints and guides do not affect the positioning of the shutter and barrel. The dimensions of the shutter are reduced, the accuracy is increased.
Возможен вариант (фиг. 2), когда контактирующие поверхности за- твора 2 и/или ствола 1 выполнены в виде одного или более отдельных элементов 4 закрепленных на затворе 2 и/или стволе 1, расположенных между внутренней поверхностью затвора 2 и наружной поверхностью ствола 1.A variant is possible (Fig. 2) when the contacting surfaces of the shutter 2 and / or barrel 1 are made in the form of one or more separate elements 4 mounted on the shutter 2 and / or barrel 1 located between the inner surface of the shutter 2 and the outer surface of the barrel 1 .
Это увеличивает срок службы и ремонтопригодность оружия. Вариантом механизма запирания (фиг. 3 и 4) является наличие одного или более боевых выступов 5 для взаимодействия при запирании с одной или более опорными поверхностями 6 ствола.This increases the service life and maintainability of the weapon. A variant of the locking mechanism (Fig. 3 and 4) is the presence of one or more combat protrusions 5 for interaction when locking with one or more supporting surfaces 6 of the barrel.
Это позволяет запирать ствол поворотом затвора и использовать более мощные боеприпасы. Также возможен вариант (фиг. 3 и 4), когда взаимодействующие при запирании поверхности затвора 2 и ствола 1, имеют конусообразную форму, с уклоном в сторону казенной части.This allows you to lock the barrel by turning the shutter and use more powerful ammunition. It is also possible (Fig. 3 and 4), when interacting with the locking surface of the shutter 2 and barrel 1, have a conical shape, with a slope towards the breech.
Это увеличивает точность позиционирования затвора и ствола.This increases the accuracy of the shutter and barrel positioning.
