Bolt braking system in firearms

Abstract

The invention relates to the restructuring of the recolt guide ( 2 ) in order to prevent the firing line from deteriorating by reducing the impact force of the bolt ( 7 ), with the recolt spring ( 5 ) that is compressed during firing and moves back together with the bolt ( 7 ) returning to its original position, while minimizing the damage to the elements that make up the pistol.

1 . Bolt ( 7 ) breaking mechanism, comprising
 a. at least one recolt guide ( 2 ) having at least two steps with different diameters in,   b. at least one nut ( 4 ) that sits inside the large diameter part of said recolt guide ( 2 ) and can move back and forth and/or rotationally along said recolt guide ( 2 ),   c. at least one set screw ( 1 ) with a threaded tip, which enters through the small diameter of said recolt guide ( 2 ) and is connected to said nut ( 4 ) by rotating,   d. at least one spring ( 3 ), that abuts to the step by entering through the large diameter of said recolt guide ( 2 ), passes over said set screw ( 1 ) and remains between said step and said nut ( 4 ), with said set screw ( 1 ) pulling said nut ( 4 ), provides a force in the opposite direction to the force that occurs when the bolt ( 7 ) returns after firing and hits the set screw head ( 1 . 1 ).   
     
     
         2 . Bolt ( 7 ) braking mechanism according to  claim 1 , comprising, at least one setting numbers group ( 2 . 1 ) on said recolt guide ( 2 ), which enables the compression value of said spring ( 3 ) to be adjusted and thus the reverse force generation value of said spring ( 3 ) is determined. 
     
     
         3 . Bolt ( 7 ) braking mechanism according to  claim 1 , comprising, at least one screw path ( 1 . 2 ) located on said set screw ( 1 ), which prevents said set screw ( 1 ) from being opened each time said bolt ( 7 ) hits said set screw head ( 1 . 1 ) after ignition by passing a screw ( 8 ) through the screw slot ( 2 . 2 ) on said recolt guide ( 2 ). 
     
     
         4 . Bolt ( 7 ) braking mechanism according to  claim 3 , characterized in that, said screw path ( 1 . 2 ) provides a range of motion for pulling said nut ( 4 ) when said bolt ( 7 ) hits said set screw ( 1 ). 
     
     
         5 . Bolt ( 7 ) braking mechanism according to  claim 1 , comprising, at least one nut screw ( 4 . 1 ) positioned in the screw slot ( 2 . 2 ) located on said nut ( 4 ), helping the full connection of said nut ( 4 ) and said set screw ( 1 ) ensuring that the movement of said nut ( 4 ) in said recolt guide ( 2 ) is limited. 
     
     
         6 . Bolt ( 7 ) braking mechanism according to  claim 1 , comprising, at least one bottom screw ( 6 ) comprising at least one protrusion to prevent said recolt spring ( 5 ) from coming off and screwed into said recolt guide ( 2 ) from its large diameter step for the exact positioning of said recolt spring ( 5 ) passing on to said recolt guide ( 2 ). 
     
     
         7 . Bolt ( 7 ) braking mechanism according to  claim 1 , comprising, at least one bottom screw pin slot ( 6 . 1 ) on the said nut ( 4 ) coinciding with the pin slot ( 2 . 5 ) opened on the said execution guide ( 2 ), and preventing the nut ( 4 ) from coming out of its place by providing full contact with said execution guide ( 2 ) by means of a pin ( 2 . 4 ).
