Spiral rotating and rigid locking mechanism for handgun

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 [0001] The invention belongs to the field of pistols, and in particular relates to a spiral rotary rigid locking mechanism of a pistol. Background technique [0002] At present, there are mainly three types of pistol locking methods in the world: freestyle, semi-freestyle and rigid locking. For high-power pistol bullets, rigid locking methods (such as Glock, Browning, Sig-Sauer, 54 Type, Colt M1911, Beretta 92F and other pistols). In the rigid locking method, most of them adopt the Browning locking (that is, the barrel swing) method (such as 54 pistols, M1911 pistols, Browning high-power pistols and other early products) or the improved Browning locking method ( Such as Glock pistols, Sig-Sauer pistols, USP pistols of HK Company, etc.), the locking method is simple in structure, but after long-term use, the locking surface will be worn and the accuracy will decrease, and there will be uneven force on the parts when opening and closing. Due to factors such a...

Problems solved by technology

In the rigid locking method, most of them adopt the Browning locking (that is, the barrel swing) method (such as 54 pistols, M1911 pistols, Browning high-power pistols and other early products) or the improved Browning locking method ( Such as Glock pistols, Sig-Sauer pistols, USP pistols of HK Company, etc.), the locking method is simple in structure, but after long-term use, the locking surface will be worn and the accuracy will decrease, and there will be uneven force on the parts when opening and closing. Due to factors such as asymmetry, the service life of the automatic parts is affected, while the pistols (such as the Beretta 92F pistol) that use the iron swing type rigid lock have a more complicated structure, and the moving parts are limited by the structure. The strength of the parts is lower than that of the Browning type. Locking method
