On the other hand, a gun accessory mounting rail R in the present embodiment may be a Picatinny rail or a Weaver rail. In this embodiment, A plurality of slits R1 are arranged at equal intervals along a total heat direction and a picatini rail installed in a total heat direction is applied.

The body 110 is disposed on the upper side of the rail R and surrounds the upper surface and one side of the rail R. The bottom surface of the body 110 is formed with a first receiving groove 111 in which the rail R is received, A first clamp 115 for enclosing one side of the rail R is formed at one side of the receiving groove 111 and a third receiving groove 111 is formed at the other side of the first receiving groove 111 for receiving the lever 130 rotatably. A groove 113 is formed. A second receiving groove 112 for receiving the fixing member 120 is formed between the first receiving groove 111 and the third receiving groove 113. An insertion protrusion 114 inserted into the lateral slit R1 of the rail R is protruded from the bottom surface of the first receiving groove 111 of the body 110 facing the rail R, A pivot shaft 118 that passes through the lever 130 and the body 110 and forms a pivot axis of the lever 130 is installed in the groove 113 in the vertical direction. The second receiving groove 112 is provided with a plurality of second guide portions 117 in the form of pins for guiding the movement of the holding member 120 along the moving direction of the holding member 120. The upper surface of the body 110 is provided with a laser site, a tactical light, a dot site, a scope, etc., a vertical handle 133, a carrying handle 133, and a flip up rear sight The accessory is fixed.

The stopper 160 selectively fixes a position of the lever 130 in a state of rotating in a fixed direction at a position spaced from a side of the pivot shaft 118 of the body 110 by a predetermined distance. The stopper 160 includes a support shaft 162 which is vertically movably installed in the inner space of the third receiving groove 113 and is axially movable, A first engaging portion 161 spaced apart in the horizontal direction in the horizontal direction and a working portion 163 formed at the other end of the supporting shaft 162 and a second engaging portion 163 between the working portion 163 and the body 110 And a third elastic member 164 disposed on the first engaging part 161 and elastically supporting the fixing member 120 in a fixing direction. The first elastic part 164 of the first engaging part 161, which is in contact with the lever 130 in the rotating direction, On one side surface, a guide surface 165 is formed so as to be inclined to guide the movement of the first engaging portion 161 in the disengaging direction.

The fixing member 120 is disposed to be movable in a direction intersecting the rail R in the second receiving groove 112 of the body 110. The first receiving groove 111 of the body 110, And the second guide portion 117 is inserted into the center of the second clamp 122 so as to slide along the second guide portion 117, And a portion 121 is formed in a horizontal direction along the moving direction of the fixing member 120.

The lever 130 is formed with a through hole 131 through which the pivot shaft 118 penetrates in the vertical direction and a handle 133 extends horizontally at one side of the through hole 131 And a pressing projection 132 is formed on the other side in a horizontal direction. The lever 130 is provided to pivot about the pivot shaft 118 in the third receiving groove 113 of the body 110 so that the pressing protrusion 132 is pivoted in the fixing direction or the pivoting direction And selectively provides a pressing force toward the fixing member 120.

Here, the 'fixed' position of the lever 130 is a state in which the lever 130 is rotated in one direction so that the pressing protrusion 132 of the lever 130 applies a pressing force toward the fixing member 120, 130 means that the lever 130 is rotated in the opposite direction and does not apply a pressing force toward the fixing member 120. [

The surface of the tip end of the pressing protrusion 132 for pressing the first elastic member 140 in a state where the lever 130 is positioned in the fixing direction has a first contact surface 132a and a second contact surface 132b. Here, the first contact surface 132a refers to a region in which the lever 130 is in continuous contact with the first elastic member 140 from the critical point in the course of rotating the lever 130 from the fixed position to the fixed release direction, The contact surface 132b refers to an area located on the opposite side of the first contact surface 132a.

That is, when the lever 130 is rotated to the fixed position, since the pressure applied from the first elastic member 140 acts more strongly on the first contact surface than the second contact surface, The rotation is prevented.

The handle 133 of the lever 130 is disposed between the support shaft 162 of the stopper 160 and the first engaging portion 161 while the lever 130 is rotated to the fixed position, The handle 133 of the lever 130 is prevented from rotating in the disengaging direction at random from the fixed position by the first engaging portion 161. [

The first elastic member 140 is disposed between the lever 130 and the fixing member 120 to resiliently maintain a gap between the lever 130 and the fixing member 120, The first and second support portions 141 and 142 are disposed toward the fixing member 120 and the lever 130, respectively, As shown in FIG. The first supporting portion 141 of the first elastic member 140 disposed in the third receiving groove 113 is inserted into the second receiving groove 112 so as to support the holding member 120 disposed in the second receiving groove 112, A through hole through which the first supporting portion 141 passes is formed in the partition wall between the groove 112 and the third receiving groove 113.

The second elastic member 150 is composed of a compression coil spring and is disposed on both sides of the moving center of the fixing member 120 between the body 110 and the fixing member 120. The second elastic member 150 elastically supports the fixing member 120 in a direction away from the rail R so that the pressing force of the lever 130 is not applied to the fixing member 120, So that the fixing member 120 is kept apart from the other side of the rail R. In this state,

Hereinafter, the operation of the first embodiment of the above-described clamping device for a gun rail will be described.

6 is a cross-sectional view taken along the line A-A 'in FIG. 5, and FIG. 7 is a cross-sectional view showing a state in which the lever 130 is fixed according to the present invention. Fig.

5 and 6, a first clamp 115, which surrounds one side of the rail R, is integrally formed on one side of the first receiving groove 111 formed on the bottom surface of the body 110, The fixing member 120 surrounding the other side of the rail R is inserted into the second receiving groove 112 formed on the other side of the receiving groove 111 in the horizontal direction in which the fixing member 120 intersects the rail R in the second receiving groove 112 As shown in Fig.

The fixing member 120 includes a first guide portion 121 formed at the center thereof and a second guide portion 117 disposed in the second receiving groove 112 in a horizontal direction, Move along. Therefore, the fixing member 120 is prevented from rotating in the left or right or up and down direction in the second receiving groove 112 in the process of reciprocating in the horizontal direction for fixing or releasing the rail R. [

The lever 130 is pivotally installed in the third receiving groove 113 of the body 110 via a pivot shaft 118 disposed in a vertical direction so that the lever 130 can be fixed or unlocked The pressing projection 132 provided on one side of the lever 130 applies or releases the pressing force in the fixing direction of the fixing member 120. [

The first elastic member 140 disposed between the lever 130 and the fixing member 120 performs a buffering action in transmitting the pressing force from the lever 130 to the fixing member 120 . Therefore, even if the width of the rail R is somewhat larger than or smaller than a predetermined standard standard, the fixing member 120 can elastically tightly fix the other side of the rail R. [

The second elastic member 150 disposed between the partition member and the fixing member 120 separates the first receiving groove 111 and the second receiving groove 112 of the body 110 from the fixing member 120, Is elastically compressed in the course of sliding in the fixed direction.

The lever 130 is rotated in the fixed direction and the handle 133 is brought into contact with the stopper 160 installed in the third receiving groove 113 to guide the lever 130 in the fixed position. Is prevented.

The first clamp 115 provided on one side of the first receiving groove 111 is engaged with the first receiving groove 111 of the body 110 on one side of the rail R while the first receiving groove 111 of the body 110 is engaged with the rail R The fixing member 120 together with the first elastic member 140 is pressed against the rails 130 by the pressing force provided by the pressing protrusions 132 of the lever 130, R, the second clamp 122 provided on the fixing member 120 surrounds the other side of the rail R and fixes it.

When the first clamp 115 and the second clamp 122 wrap the both sides of the rail R and fix the body 110 to the rail R, the pressing projections 132 of the lever 130 Is transmitted to the fixing member 120 through the first elastic member 140. The pressing force is transmitted to the fixing member 120 through the first elastic member 140. [ Therefore, even when the width of the rail R is larger than or smaller than the standard standard, the other side of the rail R can be held firmly while being firmly fixed, It is possible to prevent a clearance from being generated between the rail R and the rail R in a fixed state.

According to the first embodiment of the present invention, the fixing member 120 is elastically and tightly supported by the side surface of the rail R by the first elastic member 140, and the first elastic member 140 is supported by the rail R And the body 110, it is possible to prevent the life of the precision aiming device mounted on the body 110 from being shortened due to the impact generated when the firearm is triggered.

Since the insertion protrusion 114 formed on the inner side surface of the first receiving groove 111 is inserted and inserted into the transverse slit R1 formed on the upper surface of the rail R, (110) is prevented from moving along the longitudinal direction of the rail (R) while being fixed to the rail (R).

7, when the lever 130 rotates in the fixing direction about the pivot shaft 118, the pressing protrusion 132 of the lever 130 presses the first elastic member 140 So that the fixing member 120 surrounds the other side of the rail (R). The first elastic member 140 is elastically compressed between the pressing protrusion 132 of the lever 130 and the fixing member 120 so that the first elastic member 140 is inserted into the pressing protrusion 132 of the lever 130, The elastic repulsive force due to the elastic force acts. That is, in the process of rotating the lever 130 from the fixed position to the fixed releasing direction among the tip ends of the pressing protrusions 132 for pressing the first elastic member 140, The resilient repulsive force of the first elastic member 140 is weighted on the first contact surface 132a since the first contact surface 132a which is brought into contact with the first contact surface 132a is protruded from the second contact surface 132b located on the opposite side of the critical point. Therefore, the lever 130 is elastically supported in the fixing direction by the elastic repulsive force of the first elastic member 140.

Further, the lever 130 is prevented from further rotating in the fixing direction by the stopper 160 in the fixed position, and is elastically supported in the fixing direction by the elastic repulsive force of the first elastic member 140 in the fixing releasing direction , The fixed position of the lever 130 is stably maintained.

The process of disassembling the clamping device fixed to the rail R as described above is as follows.

8 is a cross-sectional view showing the clamping device for a gun rail according to the present invention, and FIG. 9 is a sectional view taken along line B-B 'of FIG.

8, when the handle 130 of the lever 130 is pivoted in the unlocking direction by gripping the handle 133, the lever 130 rotates around the pivot shaft 118, The pressing force applied to the first elastic member 140 is released while the second elastic member 132 moves to the side of the first elastic member 140. [

The pressing force of the pressing protrusion 132 is released from the second elastic member 150 elastically compressed between the partition wall between the first receiving groove 111 and the second receiving groove 112 and the fixing member 120 So that the fixing member 120 is pushed out in the unlocking direction. The fixing member 120 has a structure in which the first guide portion 121 formed at the center is slid along the second guide portion 117 coupled to the second guide portion 117 of the body 110, ) ≪ / RTI >

9, as the fixing member 120 moves in the fixing releasing direction, the second clamp 122 of the fixing member 120 is separated from the other side of the rail R, Is detachable from the rail (R). The body 110 can be separated from the rail R by lifting the other side of the body 110 around the first clamp 115 which surrounds one side of the rail R as shown in the drawing.

Since the fixing member 120 is elastically supported in the fixing releasing direction by the second elastic member 150 and is prevented from moving to the fixing side during the process of separating the body 110 from the rail R, Is prevented from interfering with the rail (R).

In the meantime, according to the first embodiment of the present invention, the lever 130 is prevented from rotating in the fixed release direction in a state of being rotated to the fixed position by the stopper 160 provided in the body 110. Hereinafter, the operation of the stopper 160 will be described in detail.

FIG. 10 is a cross-sectional view showing a locked state of the stopper 160 according to the clamping device for gun barrel according to the present invention, and FIG. 11 is a cross-sectional view showing the unlocked state of the stopper 160 according to the clamping device for a gun barrel to be.

The acting portion 163 is fixed to the other end of the supporting shaft 162 and the acting portion 163 is elastically supported in the fixing direction by the third elastic member 164 interposed between the supporting shaft 162 and the body 110 .

The first engaging portion 161 provided at one end of the supporting shaft 162 is fixed on the moving region of the lever 130 as the operating portion 163 is resiliently supported by the third elastic member 164, The protruded state is maintained.

10 shows a state in which the lever 130 is fixed by the stopper 160 in a state where the lever 130 is rotated in a fixed state and the handle 133 of the lever 130 is supported by the support shaft 162 in the fixing direction Rotation is limited and the rotation in the unlocking direction is restricted by the first engaging portion 161 spaced apart in the direction parallel to the support shaft 162. [

Particularly, as described above, since the first engaging portion 161 is resiliently supported in the fixing direction by the third elastic member 164, the first engaging portion 161 arbitrarily moves in the unlocking direction . Therefore, it is possible to prevent the lever 130 from rotating in the unlocking direction at random from the fixed position.

11, when the stopper 160 is unlocked in order to rotate the lever 130 in the unlocking direction, the upper surface of the operating portion 163 fixed to the other end of the supporting shaft 162, In the downward direction. The first engaging portion 161 provided at one end of the supporting shaft 162 is lowered together with the supporting shaft 162 by the urging force externally supplied from the outside, Releasing direction side moving region of the lever 133 of the lever 130 as shown in Fig. That is, when the operating portion 163 is pressed, the first engaging portion 161, which restricts the rotation of the handle 133 in the disengaging direction, The handle 133 of the lever 130 can be rotated in the unlocking direction.

When the operating portion 163 is pressed as described above, the third elastic member 164 interposed between the operating portion 163 and the body 110 is elastically compressed. The third elastic member 164 is resiliently restored and the operation portion 163 is pushed up in the upward direction and the first engagement portion 161 is rotated together with the support shaft 162, To the fixed position.

When the lever 130 is rotated in the fixed direction from the fixed release position while the stopper 160 is moved to the fixed position as described above, in the process of moving the handle 133 of the lever 130 to the fixed position The first engaging portion 161 contacts the guide surface 165 of the first engaging portion 161 to press the first engaging portion 161. The first engaging portion 161 is lowered by the contact of the handle 133 of the lever 130 with the guide surface 165 and the handle 133 of the lever 130 is moved downward by the support shaft 162 and the first engaging portion 161, The elastic force of the third elastic member 164 is restored to the fixed position by the elastic restoring force of the third elastic member 164 as soon as it moves out of the upper side of the first engaging portion 161.

Therefore, in the process of rotating the lever 130 in the fixing direction, it is not necessary in the process of releasing the stopper 160 separately.

Hereinafter, a first modification of the stopper 160 according to the clamping device for a gun rail according to the present invention will be described.

Accordingly, the stopper 160 'can slide along the guide groove 166a in a state where the end portion of the handle 133 is wrapped.

A third elastic member 164 is disposed between the operating portion 163 of the stopper 160 'and the handle 133 of the lever 130. The operating portion 163 of the stopper 160 'is resiliently moved away from the handle 133 by the third elastic member 164 so that the opposite side of the operating portion 163 with the handle 133 therebetween The first engaging portion 161 disposed on the second engaging portion 163 is engaged with the second engaging portion 167 while moving in the fixing direction together with the action portion 163. [
