Abstract
The invention discloses a gunlock speed reduction mechanism of a pistol, and belongs to the technical field of pistols. The gunlock speed reduction mechanism comprises a gunlock, a gun barrel and a binding base. The gun barrel is rotationally installed on the binding base. A spiral groove is formed in the gunlock. A protrusion corresponding to the spiral groove is arranged on the gun barrel. When the gunlock recoils, the protrusion collides with the spiral groove, part of energy of gunlock recoiling is offset, and the aim of gunlock speed reduction is achieved. When the pistol using the gunlock speed reduction mechanism fires a bullet, the gunlock recoils in place at a low speed, the phenomenon that an existing pistol is prone to causing obvious hand shaking is eliminated, and the shooting comfort degree is improved. In addition, the gunlock speed reduction mechanism further has the beneficial effects of being simple in structure, good in reliability, wide in application range and the like.
Description
Technical field
The invention belongs to pistol technical field, relate to the gunlock reducing gear of a kind of pistol.
Background technology
At present, the automated manner of pistol mainly has free gunlock and semi-free gunlock (pipe withdrawing type removes in the world
Outward).Both modes gunlock after percussion is unblanked is all freely-movable, owing to not designing reducing gear,
During percussion bullet, gunlock recoil is fast to bit rate, especially when the cartridge shooting that use gun pressure is higher, and rifle
The recoil energy of machine is big, and the speed that gunlock recoil puts in place is the most faster, it may appear that significantly shake hands phenomenon, penetrates
The comfort level hit is poor, and fire accuracy is bad.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the gunlock reductor of a kind of pistol
Structure, it can efficiently reduce energy during gunlock recoil, and then reduce the speed that gunlock recoil puts in place.
The object of the present invention is achieved like this:
The gunlock reducing gear of a kind of pistol, including gunlock, gun barrel and coupling seat, described gun barrel can turn
Being arranged in described coupling seat, the face of described gunlock correspondence gun barrel is provided with gathering sill, described guiding dynamicly
Groove includes helicla flute, the first straight trough being positioned at helicla flute rear end and is positioned at the second straight trough of helicla flute front end,
The central axes of described spiral fluted helical centre and described gun barrel, described first straight trough and the
Two straight troughs all axially extending along described gun barrel, described gun barrel is provided with the projection embedding gathering sill；
During normality, described projection is positioned at the first straight trough；
When gunlock recoil, first, described projection is moved to helicla flute in the first straight trough relative to gunlock,
Then, described projection is collided with helicla flute, counteracts the part recoil energy of gunlock, then, described convex
Playing entrance helicla flute and drive described gun barrel to rotate under spiral fluted effect, finally, described projection is left
Helicla flute enters the second straight trough and continues motion, until gunlock recoil puts in place.
Preferably, the shape of described projection is corresponding with helicla flute and forms spiral boss.
Preferably, during described gunlock recoil 3.5mm, described spiral boss collides with helicla flute.
Preferably, the rear end of described gun barrel is provided with step, and described coupling seat is provided with stopper slot, described
Component level is in stopper slot, for gun barrel axial limiting.
Owing to have employed technique scheme, there is advantages that
The present invention is provided with gathering sill on existing gunlock, is provided with helicla flute, at rifle in gathering sill
The spiral boss corresponding with helicla flute it is provided with on pipe, as gunlock recoil 3.5mm, helicla flute and spiral
Boss collision counteracts the portion of energy in gunlock recoil, and the energy in gunlock recoil diminishes, and gunlock recoil puts in place
Speed will reduce, be just difficult to occur significantly shaking hands phenomenon during percussion bullet, improve relaxing of shooting
Appropriateness so that the fire accuracy of pistol is good；Meanwhile, the present invention also has simple in construction, good reliability, fits
By the advantage such as in extensive range.

In figure, label is described as follows:
1 is gunlock, and 2 is gun barrel, and 3 is recoil rod, and 4 is coupling seat, and 5 is spiral boss, and 6 are
Gathering sill, 61 is helicla flute, and 62 is the first straight trough, and 63 is the second straight trough.
Detailed description of the invention
Below embodiments of the invention are described further.
Seeing Fig. 1-Fig. 6, a kind of embodiment of the gunlock reducing gear of pistol, including gunlock 1, gun barrel 2
And coupling seat 4, the middle part of described coupling seat 4 is provided with endoporus, and described endoporus is covered with recoil rod 3,
Being equipped with kicker on described recoil rod 3, the other end of described recoil rod 3 imports gunlock 1
The recoil rod hole inner support that front lower portion is provided with, the upper end of described coupling seat 4 is provided with arc groove, institute
The rear end stating gun barrel 2 is provided with the step of the arc-shaped corresponding with described arc groove, and described step is rotationally
Being socketed in described arc groove, for gun barrel 2 axial limiting, the medial surface of described gunlock 1 is provided with
Gathering sill 6, described gathering sill 6 includes helicla flute 61, is positioned at the first straight trough 62 of helicla flute 61 rear end
And it being positioned at the second straight trough 63 of helicla flute 61 front end, the helical centre of described helicla flute 61 is with described
The central axes of gun barrel 2, described first straight trough 62 and the second straight trough 63 are all along described gun barrel 2
Axially extending, described gun barrel 2 be provided with embed gathering sill 6 spiral boss 5, described spiral boss 5
Shape corresponding with helicla flute 61.
Mechanism is the gunlock of a kind of gun barrel swinging inertia locking, gun barrel connecting mode, during normality, institute
State spiral boss 5 and be positioned at the first straight trough 62；When unblanking, described gunlock 1 recoil, first, described
Spiral boss 5 moves to helicla flute 61 in the first straight trough 62 relative to gunlock 1, when gunlock 1 recoil
During 3.5mm, described spiral boss 5 collides with helicla flute 61, counteracts the part recoil energy of gunlock 1,
Then, described spiral boss 5 enters helicla flute 61 and drives described gun barrel 2 under the effect of helicla flute 61
