Abstract
The invention discloses a spiral rotating and rigid locking mechanism for a handgun. The spiral rotating and rigid locking mechanism is mainly characterized in that interval spiral locking and supporting teeth buckled mutually are arranged on an inner cavity of a bolt and the peripheral face of a barrel for spiral locking. Meanwhile, interval connected flap teeth buckled mutually are arranged at the front end of the inner cavity of the bolt and the peripheral face of a tubular protruding part of a barrel sleeve for locking. A spiral rotating boss is arranged at the rear end of the barrel. A spiral groove matched with the spiral rotating boss is formed in the upper portion of a connecting base and used for enabling the barrel to rotate or rotate back to be reset. The handgun adopting a locking mode is high in safety, good in speed reduction effect and beneficial to improving shooting precision and reliability and prolonging the service life, and recoil energy is adjustable.
Description
Technical field
The invention belongs to firearms art, be specifically related to a kind of spiral revolution rigid locking mechanism of pistol.
Background technology
At present, pistol closedown mode mainly contains free style, semi-free formula and rigid locking three kinds of modes in the world, for high power pistol bullet, all adopt rigid locking mode (as Ge Luoke, Browning, John Moses, Xi Ge-continue the pistol such as that, 54 formulas, Coalter M1911, Beretta 92F).In rigid locking mode, major part adopts Browning, John Moses locking (i.e. gun barrel swing type) mode (as 54 formula pistols, M1911 pistol, the early productions such as Browning, John Moses high power pistol) or improvement after Browning, John Moses closedown mode (as Ge Luoke pistol, Xi Ge-continue your pistol, the USP pistol etc. of HK company), this closedown mode structure is simple, but can precise decreasing be caused after latch surfaces wearing and tearing after Long-Time Service, existence is opened, parts discontinuity during locking, the factor such as asymmetric, automatic parts are affected service life, and adopt the pistol of gib swing type rigid locking (as Beretta 92F pistol) structure more complicated, moving parts are subject to structure restriction parts intensity lower than Browning, John Moses formula closedown mode.
