Specific embodiment
Refer to shown in Fig. 1 to Fig. 2, that show the concrete structure of guide track system of the present invention, the guide track system is installed
In the erecting bed of the equipment such as firearms（Do not show）On, the erecting bed is generally the dovetail shaped of projection, and the guide track system is provided with
The clamping device of integral type, the clamping device includes body 1, the first screw 2, the second screw 3 and the 3rd screw 4.
The body 1 is made up of metal material, and it is the structure of integral type, and from the side, body 1 is substantially in " ㄇ " shape
Shape, it includes a connecting portion 11 and the left clamping part 12 and right clamping part 13 that are respectively extended downwardly out from the both sides of connecting portion 11, should
Two clamping parts collectively form a grasping part 14 with connecting portion 11, for being clamped on the erecting bed of the equipment such as firearms, by body 1
It is held in position with erecting bed；The left clamping part 12 includes left elastic arm 121 and from the bottom of left elastic arm 121 to grasping part
The left teat 122 of projection in 14, the right clamping part 13 includes right elastic arm 131 and from right elastic arm bottom 131 to clamping
The right teat 132 of projection in space 14, the teat of left and right two is used to be held on erecting bed, prevents body 1 from being released with erecting bed；
The left elastic arm 121 and right elastic arm 131 are both designed to appropriate elasticity, under external force, left clamping part 12
It is capable of inwardly tightening or expand outwardly for elasticity with right clamping part 13, to drive the change of the lateral separation of grasping part 14, so that
So that the grasping part 14 can be engaged with the erecting bed of multiple different in width.
The left elastic arm 121 is provided with some first screws 123 for running through（Screw thread is not shown）, on right elastic arm 131
It is provided with some second screws 133 for running through（Screw thread is not shown）, first screw 123 is concentric with the second screw 133, but the
The aperture of one screw 123 is small compared with the second screw 133, to enable first 2 the second spiral shell directly from right elastic arm 131 of screw
Hole 133 is passed through without being threadedly coupled with the second screw 133.
First screw 2, it is provided with screw rod more long, and the convex portion 21 of arcuation is provided with one end of screw rod, and relative is another
One end is provided with hexagon socket head cap screw hole, for for hexagon spanner rotation, first screw 2 is threadedly coupled with the first screw 123.
Second screw 3, it is provided with shorter screw rod, and the recess 31 of taper is set in one end of screw rod, relative
The other end is provided with hexagon socket head cap screw hole, for for hexagon spanner rotation, the screw 133 of the second screw 3 and second carries out screw thread company
Connect.The recess 31 can carry out correcting with foregoing convex portion 21 after mutually extruding stress, prevent the first screw 2 and the second screw
3 shift in extruding, and can not effectively carry out elastic dilatation.
3rd screw 4, its with connecting portion 11 on screwed hole coordinate after, and be threadedly connected to the peace of the equipment such as firearms
On dress platform, to prevent from being loosened before and after the body 1 after installing.
Refer to shown in Fig. 3, for grasping part 14 more than or equal to the width of erecting bed, its clamp method on firearms
For：First, the appropriate location by the slip cap of guide rail body 1 on the erecting bed of the equipment such as firearms；Secondly, by the first screw 2
The second screw 133 from right clamping part 13 is passed through, then is rotated with hexagon spanner, the first screw 2 is occurred with the first screw 123
Threaded connection；Again, the first screw 2 is further tightened, due to tightening the pulling force of generation, drives two clamping parts of left and right to clamping
Tightened in space 14, so that two clamping parts are consolidated on the erecting bed for clamping the equipment such as firearms；Finally, then by the 3rd screw
4 are threadedly connected in the corresponding screw on erecting bed from the top down, most the firm installation for being installed on the equipment such as firearms of body 1 at last
On platform.
Refer to shown in Fig. 4, for grasping part 14 less than the erecting bed width in the equipment such as firearms, its clamp method
For：First, after the second screw 3 is threadedly coupled in place with the second screw 133, while the first screw 2 and the first screw 123 are opened
Beginning is threadedly coupled；Secondly, the first screw 2 is exerted oneself（Use hexagon spanner）Rotation gradually deeply, now, the first screw and the
Two screws are extruded in the cooperation correcting lower stress of convex portion 21 and recess 31 so that the first screw 2 and the second screw 3 are extruded in stress
There is stress skew in Shi Buhui, when the first screw 2 is further rotated, the first screw 2 and the second screw 3 now are produced because extruding
Extruding force react on left and right two elastic arms on, drive left and right two clamping parts elasticity expand outwardly, by grasping part 14
Lateral separation expand and can be engaged with erecting bed；Again, by the slip cap of body 1 after expansion located at equipment such as firearms
Behind appropriate location on erecting bed, then any screw is unclamped with hexagon spanner（First screw 2 or the second screw 3）, now or so
The elastic force of two elastic arms is released, and two clamping parts of left and right is clamped erecting bed；Then, refer to shown in Fig. 3, be more one
Step strengthens the chucking power of two clamping parts of left and right, and the second screw 133 by the first screw 2 from right clamping part 13 is passed through, Ran Houyong
Hexagon spanner rotation makes the first screw 2 be threadedly coupled with the first screw 123, and makes left and right two by tightening the pulling force of generation
Two clamping parts are consolidated and are clamped on the erecting bed of the equipment such as firearms by clamping part to being tightened in grasping part 14；Finally, then will
3rd screw 4 is threadedly connected in the corresponding screw on erecting bed from the top down, and most body 1 consolidates the peace for being installed on firearms at last
On dress platform.
Referring again to shown in Fig. 2, the guide track system is additionally provided with support（Do not indicate）, the supporting portion is in connecting portion
11 top, for supporting or installing the rifle annex such as gun sight and torch, to increase the use function of rifle；When support and company
When the differentiation of socket part 11 is not obvious, it is also possible to by support when connecting portion is used, will both be considered as same position, for connecting
Two clamping parts of left and right.
The above, is only presently preferred embodiments of the present invention, and not technical scope of the invention is imposed any restrictions,
Therefore every any trickle amendment, equivalent variations and modification made to above example according to technical spirit of the invention, still
Belong in the range of technical solution of the present invention.
