Description

Technical Field

[0001] The present application relates to the technical field of firearm sight calibration, and in particular to a firearm sight calibrator. Background Art

[0002] Calibrating your firearm's sights is a critical step that directly affects your shooting accuracy and efficiency.

[0003] A firearm sight calibrator is a device used to align a firearm's sight with the barrel bore. To use it, the sight is inserted into the barrel bore, aligning its axial centerline with the bore's. A laser beam is then fired at the target, and the reflected laser beam is used to determine the offset of the crosshairs. Finally, the center position of the sight's crosshairs is precisely determined, ensuring that the bullet lands at the center of the sight's crosshairs during live-fire shooting. Therefore, the precision with which the sight is installed in the barrel bore directly impacts the accuracy and efficiency of your shots.

[0004] At present, firearm sight calibrators on the market generally use expanders to adapt to gun barrels of different calibers. However, due to the installation structure of the expander, the expander cannot fit tightly with the inner wall of the barrel hole, causing the firearm sight calibrator to lose its required accuracy.

[0036] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0037] See also Figure 1-Figure 4 , shows a calibration instrument for a firearm sight according to a preferred embodiment of the present invention, comprising:

[0038] The housing 1 is provided with a first tapered portion 11 and a second tapered portion 12. The first tapered portion 11 and the second tapered portion 12 are arranged in sequence along the length direction of the housing 1. The first tapered portion 11 is adapted to fit the muzzle of a gun barrel, and the second tapered portion 12 is configured to be inserted into the bore of the gun barrel.

[0039] The expander 3 has a reduced diameter state in which the expander 3 can enter and exit the barrel hole, and an expanded diameter state in which the expander 3 is expanded by the second tapered portion 12 to fit the barrel hole; and

[0040] The adjusting mechanism 2 is movably provided on the shell 1. The adjusting mechanism 2 is connected to the expander 3. The adjusting mechanism 2 is used to drive the expander 3 to move so that the expander 3 can move to cooperate with the second tapered portion 12, thereby enabling the expander 3 to switch from a reduced diameter state to an expanded diameter state. When the calibrator of the present invention is in use, the expander 3 is inserted into the barrel hole until the first tapered portion 11 and the barrel mouth are adapted, so that the first tapered portion 11 is tightly connected to the barrel mouth, and then the adjusting mechanism 2 is operated to drive the expander 3 to move to cooperate with the second tapered portion 12, so that the expander 3 can switch from a reduced diameter state to an expanded diameter state, thereby enabling the expander 3 to adapt to the barrel hole, that is, the expander 3 and the barrel hole are tightly connected. In combination with the tight connection of the first tapered portion 11 and the barrel mouth, the axial center line of the shell 1 is limited to the same position as the barrel. The axial center lines of the holes coincide, thereby aligning the sight with the barrel hole. Since the expander 3 is expanded by the second conical portion 12, the change in the inclination of the conical surface of the second conical portion 12 can ensure that the expander 3 is fully expanded to fit tightly with the barrel hole, which can effectively avoid the situation where the axial center line of the shell 1 and the axial center line of the barrel hole do not coincide due to the expander 3 not being able to fit tightly with the barrel hole, thereby greatly improving the alignment accuracy of the sight. In addition, this calibrator has a simple and practical structure, and the adjustment operation is simple and convenient, which can greatly improve the alignment efficiency.

[0041] It can be understood that the expander 3 is provided with an expansion portion, the expansion portion has a socket, and the socket cooperates with the second tapered portion 12 so that the second tapered portion 12 can expand the expansion portion and switch the expander 3 to the expanded state.

[0042] In one embodiment, the expander 3 may be a structure made of plastic material or a structure made of metal material.

[0043] In one embodiment, the expander 3 is detachably mounted on the adjustment mechanism 2 so that expanders 3 with different outer diameters can be replaced, thereby enabling the calibrator to be adapted to gun barrels with different diameters.

[0044] See also Figure 4 In one embodiment, the adjustment mechanism 2 includes:

[0045] A moving rod 21, the moving rod 21 is movably inserted into the housing 1, and the moving rod 21 has a first connecting portion and a second connecting portion, and the first connecting portion is connected to the expander 3; and

[0046] The adjusting nut 22 is threadedly connected to the second connecting portion. When the adjusting nut 22 is rotated, the moving rod 21 can be driven to move. In this way, the moving rod 21 can be driven to move by rotating the adjusting nut 22. The movement of the moving rod 21 can drive the expander 3 to move in the barrel hole. This adjustment structure is simple and practical, easy to operate, and has high structural reliability.

[0047] See also Figure 1 , in one embodiment, the expander 3 is sleeved on the first connecting portion;

[0048] The regulating mechanism 2 further comprises:

[0049] The locking nut 23 is threadedly connected to the first connecting portion and is used to prevent the expander 3 from being separated from the moving rod 21. In this way, the lock nut 23 can prevent the expander 3 from being separated from the moving rod 21. At the same time, the expander 3 can be separated from the moving rod 21 by unscrewing the lock nut 23. The structure is simple and practical, and it is convenient to replace expanders 3 of different sizes.

[0050] In one embodiment, the moving rod 21 comprises:

[0051] A first moving member 211, the first moving member 211 having a second connecting portion; and

[0052] The second moving member 212 is separately provided with the first moving member 211. The second moving member 212 is provided with a first connecting portion, and one end of the second moving member 212 facing away from the first connecting portion is connected to the first moving member 211. That is, the moving rod 21 is composed of the first moving member 211 and the second moving member 212 which are separately provided. During installation, the first moving member 211 and the adjusting nut 22 can be installed on the housing 1 first, and then the second moving member 212 can be connected to the first moving member 211. Finally, the expander 3 and the locking nut 23 can be installed. This can reduce the difficulty of installing the adjusting mechanism 2 and make the installation more convenient.

[0053] In one embodiment, the first movable member 211 has a first threaded hole, and the end of the second movable member 212 away from the first connecting portion is screwed to the first threaded hole, and an adhesive layer is provided between the end of the second movable member 212 away from the first connecting portion and the first threaded hole, which facilitates the quick connection between the first movable member 211 and the second movable member 212, and can also reliably fix the first movable member 211 and the second movable member 212 together, effectively limiting the rotation of the second movable member 212 relative to the first movable member 211.

[0054] Of course, in other embodiments, the first moving member 211 and the second moving member 212 may also be connected together by snapping.

[0055] In one embodiment, the adjustment mechanism 2 further includes:

[0056] A stopper (not shown) is provided on the housing 1 and abuts against the moving rod 21 to limit the rotation of the moving rod 21 and ensure that the moving rod 21 can only move in a straight line.

[0057] See also Figure 2 and Figure 4 In one embodiment, the adjustment mechanism 2 further includes:

[0058] The limiting member 24 is provided on the housing 1 , and the limiting member 24 and the end of the moving rod 21 facing away from the expander 3 abut against each other, ensuring that the expander 3 can fit tightly with the barrel hole, and can also limit the moving stroke of the expander 3 .

[0059] Of course, in other embodiments, the adjustment mechanism 2 may only include the moving rod 21 . The moving rod 21 may be fixed to the housing 1 by a snap-fitting manner, and may also move along the housing 1 .

[0060] See also Figure 3 In one embodiment, the shell 1 has a cavity 13, a second threaded hole 14 and a third threaded hole 15. The cavity 13 extends along the length direction of the shell 1. The cavity 13 accommodates at least a portion of the moving rod 21 and allows the moving rod 21 to move. The second threaded hole 14 is connected to the cavity 13. The second threaded hole 14 and the stopper are screwed together so that the stopper is reliably fixed on the shell 1. At the same time, the stopper can be quickly installed. The third threaded hole 15 is connected to the cavity 13. The third threaded hole 15 and the limiter 24 are screwed together so that the limiter 24 is reliably fixed on the shell 1. At the same time, the limiter 24 can be quickly installed.

[0061] Of course, in other embodiments, the anti-rotation member can also be fixed to the housing 1 by snapping.

[0062] Of course, in other embodiments, the limiting member 24 can also be fixed to the housing 1 by snapping.

[0063] In one embodiment, the adjusting nut 22 is disposed within the housing 1, which has an operating opening 16. The operating opening 16 is configured to expose at least a portion of the outer peripheral wall of the adjusting nut 22 to the housing 1, thereby enabling the adjusting nut 22 to be rotated. Thus, a user can insert a finger into the housing 1 through the operating opening 16 and contact the adjusting nut 22 to rotate the adjusting nut 22. This simple and convenient operation also serves to house most of the structure within the housing 1, effectively preventing the adjusting nut 22 from escaping from the housing 1.

[0064] In one embodiment, the operating opening 16 can allow the adjusting nut 22 to enter and exit the housing 1 , so as to facilitate installation of the adjusting nut 22 on the housing 1 .
