Specific embodiment
The embodiments of the present invention are described in further detail with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of sniper rifle gun stock connection structure, including the body of a gun 1, gun stock body 4 and for connecting
The gun stock interface 3 of the body of a gun and gun stock body, gun stock interface front end are connect by shaft 2 with the body of a gun 1.4 front end of gun stock body has
Sleeve column 402, gun stock interface rear end are correspondingly provided with the vallecular cavity 9 for the sleeve column 402 accommodating, and the sleeve column 402 is along axial direction
It stretches and is placed in the vallecular cavity 9, and can be slid back and forth along the vallecular cavity 9, the outer circumference surface of 402 front end of sleeve column is turned over equipped with annular
Side, inner wall of the vallecular cavity close to body of a gun one end are equipped with annular convex platform, and annular flange and annular convex platform cooperate, to the sleeve column
402 form axial limiting.
Be equipped with Buffer Unit 5 between the sleeve column top surface and the vallecular cavity bottom surface, the Buffer Unit 5 by hydraulic stem and
The compressed spring composition being set on hydraulic stem, hydraulic stem one end and sleeve column top surface contradict, and the other end is supported with the vallecular cavity bottom surface
Touching.For the ease of the installation of Buffer Unit, the sleeve column top surface is along the location hole being axially arranged with for Buffer Unit accommodating, institute
It states hydraulic stem one end and stretches and be placed in the positioning hole, the other end and 9 bottom surface of vallecular cavity contradict.
Outer circumference surface at 402 middle part of sleeve column is corresponded to along the limiting slot 401 penetrated through, the limiting slot is axially arranged with
Gun stock interface on be fixed with Limit screw 6, Limit screw bottom end is fallen into limiting slot 401, and sleeve column 402 is along the vallecular cavity 9
When sliding back and forth, Limit screw 6 is slidably matched with limiting slot 401.In this way, Limit screw 6 and limiting slot 401 cooperate, rifle is limited
Base body moves forward and backward in vallecular cavity 9 along fixed-direction, and gun stock body 4 is effectively prevent to rotate.
The sleeve column 402 is equipped with pressing tight plate 7 at the symmetrical periphery of the limiting slot 401, and the gun stock interface is corresponding
Ground offers rectangle relief hole 301, and the pressing tight plate 7 is stepped down by the relief hole 301 and contradicted with the sleeve column periphery, and institute
It is corresponding with 401 length of limiting slot to state 301 length of relief hole.Pressing tight plate 7 is fixed on gun stock body 4 by screw 8,7 He of pressing tight plate
Screw 8 is clearance fit, and pressing tight plate 7 can do a small amount of front and back adjustment, adjust front-rear position, reduce or eliminate Limit screw with this
6 with the fit clearance of limiting slot 401.
When bullet goes out muzzle, recoil of the body of a gun 1 by opposite direction, recoil is transmitted to gun stock by shaft 2 and connects
On mouth 3, Buffer Unit 5 relatively moves gun stock interface 3 with gun stock body 4, and then absorbs the energy that powder burning is discharged,
Mitigate impact of shooter's shoulder by gun stock recoil.The limit on relief hole 301 and gun stock body sleeve column 402 on gun stock interface 3
Position slot 401, forms gas passage, can prevent gun stock interface 3 from being formed in relative movement with gun stock body 4 while being easily installed
Closed space and cause the energy-absorbing effect of Buffer Unit 5 to reduce.
The gun stock body 4 is with the gun stock interface 3 in sliding cooperation, the maximum distance L of the two relative motion0Less than described
Maximum distance L of the Limit screw along the sliding slot relative motion1.L simultaneously0Again smaller than the pressing tight plate 7 of stating along gun stock resigning
The maximum distance L that hole 301 moves2。
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that；
