Shotgun handguard and barrel locking mechanism

Abstract

The invention relates to a shotgun handguard and barrel locking mechanism comprising a handguard, an upper barrel, a lower barrel, and a middle fixing seat assembly. The upper barrel and the lower barrel are connected through the middle fixing seat assembly. The middle fixing seat assembly comprises a seat body, a spring, a steel ball, a handguard locking bar, a countersunk head screw set, a locking steel ball, and a handguard button seat. The spring and the handguard locking bar are symmetrically arranged in a stepped hole. Arc separation grooves are symmetrically provided close to a square recess on the handguard locking bar. The middle fixing seat assembly is closely connected with the handguard through a handguard locking seat. A locking groove corresponding to the locking steel ball is arranged in the inner side of the handguard locking seat. The mechanism provided by the invention has the advantages of simple structure and reasonable design. During a shotgun application process, impact load between the barrel and the handguard can be minimized, such that weapon hit precision can be improved. Also, the connection between the handguard and the barrel is more reliable, and detachment is more convenient.

Description

technical field [0001] The invention relates to a shotgun, in particular to a locking mechanism for a handguard and a barrel of a shotgun. Background technique [0002] At present, the connection mode between the handguard and the gun barrel of the known shotgun is as follows: the handguard is equipped with a support plate, and a bamboo shoot is welded below the barrel, and the gun barrel is installed on the support plate of the handguard and passes through the support plate. The spring locking mechanism on the top is locked to ensure that its relative position is inconvenient. Although this connection method is reliable, it is difficult to disassemble and inconvenient to repair and maintain. Due to the direct contact between the barrel and the handguard, the shooting accuracy of the shotgun is reduced. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide a locking mechanis...
