The frame for movement in rifle life-span.
To achieve these goals, this utility model have employed following technical scheme:
A kind of frame for movement improving the pistol life-span, including grip base and the support plate of steel, described support plate is by dividing
Solving knob to be fixed in grip base with trigger pin, the top of described grip base is provided with one guide groove, and the upside of described guide groove is provided with
The positive stop strip being parallel to each other with guide groove, to both sides, extension is provided with raised line, the width of described raised line and limit on the top of described support plate
The width of position bar is identical, and positive stop strip is mutually linked with raised line, and it is complete that described guide groove is connected formation with the side of the bottom of raised line
Guide rail.
Preferably: described positive stop strip is cambered surface with the interface of raised line.
Preferably: described raised line is bent upwards away from one end of positive stop strip.This one end uses round-corner transition
Structure substantially reduces stress and concentrates.
This utility model uses technique scheme, and the structure after improvement is that the rear end of grip base guide rail is accomplished steel
On support plate, the ability of the collapse resistance of guide material increases, and this utility model improves rear support plate near combined axis
The stress value occurred is less than the stress on guide rail, and less than the half of guide rail upper stress, the service life being effectively increased guide rail enters
And improve the service life of firearms.

Restriction.
In description of the present utility model, it is to be understood that term " " center ", " longitudinally ", " laterally ", " length ", " width
Degree ", " thickness ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " up time
Pin ", the orientation of the instruction such as " counterclockwise " or position relationship be based on orientation shown in the drawings or position relationship, be for only for ease of
Describe this utility model and simplifying describe rather than instruction or the hint device of indication or element must have specific orientation,
With specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can express or
Implicitly include one or more this feature.In description of the present utility model, except as otherwise noted, the implication of " multiple "
It is two or more, unless otherwise clear and definite restriction.
In this utility model, unless otherwise clearly defined and limited, term " install ", " being connected ", " connection ", " Gu
Fixed " etc. term should be interpreted broadly, connect for example, it may be fixing, it is also possible to be to removably connect, or be integrally connected；Can
To be mechanical connection, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi
The connection of two element internals.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in this utility model.
In this utility model, unless otherwise clearly defined and limited, fisrt feature second feature it " on " or it
D score can include that the first and second features directly contact, it is also possible to includes that the first and second features are not directly contact but logical
Cross the other characterisation contact between them.And, fisrt feature second feature " on ", " top " and " above " include
One feature is directly over second feature and oblique upper, or is merely representative of fisrt feature level height higher than second feature.First is special
Levy second feature " under ", " lower section " and " below " include fisrt feature immediately below second feature and obliquely downward, or only

A kind of frame for movement improving the pistol life-span as shown in Figure 1, including the support plate 2 of grip base 1 and steel, described
Support plate 2 is fixed in grip base 1 with trigger pin by decomposing knob, and the top of described grip base 1 is provided with one guide groove 11, institute
The upside stating guide groove 11 is provided with the positive stop strip 12 being parallel to each other with guide groove 11, and to both sides, extension is provided with on the top of described support plate 2
Raised line 22, the width of described raised line 22 is identical with the width of positive stop strip 12, and positive stop strip 12 is mutually linked with raised line 22, described in lead
Groove 11 is connected the guide rail that formation is complete with the side 21 of the bottom of raised line 22.Described positive stop strip 12 is arc with the interface of raised line 22
Face.Described raised line 22 is bent upwards away from one end of positive stop strip 12.For guaranteeing that gunlock sentences the accuser to the punishment facing the person he falsely accused the direction of the shock that puts in place unanimously, gunlock
Front end impact basifacial is removed, and only retains top striking face.
Knowable to automat cycle of operation, gunlock, during whole back seat, causes guide rail to ftracture the section stress main moment
It is that back seat puts in place moment.Gunlock is carried out force analysis and understands gunlock to be made speed moment vanishing when back seat puts in place, then must
So by great role power F1 forward, power F1 makes gunlock produce turning torque M around its barycenter, and gunlock to be made reached in moment
The balance of power, the most necessarily by the handle guide rail directed force F to it, the counteracting force F ' of this power F acts on guide rail, from holding
The structural analysis of guide rail is understood, imperfect due in the middle part of guide rail, easily produce stress and concentrate, and in repeated firing process
In, easily producing fatigue rupture, this is the reason place of guide rail cracking.
Before and after improvement, structure has following feature: (1) improves fromer rail material is aluminium alloy Lc4, leads after improvement
Rail material is 40CrA.The ability of the collapse resistance of guide material increases.(2) improving fromer rail Tensile fracture thickness is
1.3mm, improving rear rail Tensile fracture minimum thickness is 2.8mm, is that the twice before improving is many.(3) the guide rail R1 after improving
Round-corner transition, reduces stress and concentrates.(4) structure after improving does not changes auto-action process, does not has full rifle auto-action
Have an impact.
Stress analysis is carried out to improving both front and back structure finite element.Two kinds of structures are applied identical load, when leading
Rail is monolateral when being 100N by F ' load, and result of calculation shows, under the effect of monolateral 100N power, improves fromer rail tail end
Big tension is 236 MPa, and the maximum tension stress improving rear rail tail end is 124 MPa, and ratio between two is 1.9.In addition, improve
The hot strength of rear rail material 40CrA, improve the hot strength of fromer rail material Lc4, ratio between two is 1.76.Comprehensive two factors above, before the guide rail bearing capacity after improvement is improvement
3.34 again.In sum, the improvement of this rifle grip base guide rail can significantly improve the former rifle life-span, at 5000 life base of former rifle
On, it is entirely capable of reaching the requirement in 10000 life-spans, and the potentiality being still improved, the secondary work on auto-action will not be produced simultaneously
With.
It should be pointed out that, that above example is only representative example of the present utility model.This utility model can also have many
Deformation.Every any simple modification, equivalent variations and modification above example made according to essence of the present utility model, all
It is considered as belonging to protection domain of the present utility model.
