This invention relates to a shaft coaxial adjustment device, and in particular to a shaft coaxial adjustment device for a gun barrel sight.

With the development of science and technology, countries around the world are currently developing new weapons that meet the needs of various troops in order to adapt to the needs of modern warfare and respond to the trends of future operations. Various new concepts and new principles of light weapons are also constantly being introduced. The main purpose of these new technologies used in weapons is to increase the shooting effectiveness and reliability of weapons, thereby improving the accuracy and durability of shooting weapons.

However, the commonly used barrel sights can provide tanks with muzzle position and aiming point corrections, thereby completing zeroing corrections and effectively improving the shooting hit rate of armored vehicles. However, the recoil brake on the barrel must be removed before the barrel sights can be installed, which causes inconvenience in use. Obviously, the traditional barrel sights can no longer meet the new tactical requirements. Therefore, after observing the above shortcomings, the creator of this case believes that the existing barrel sights really need to be improved, and thus the creation of this creation is produced.

The purpose of this invention is to provide a coaxial adjustment device for the axis of a gun barrel sight, which has the convenience of being used directly without removing the muzzle brake.

To achieve the above-mentioned purpose, the invention provides a coaxial adjustment device for the axis of a barrel sight, which includes: a coupling rod; an adjustment member, which includes an extension rod and an adjustment rod, the extension rod is assembled to the coupling rod, and the extension rod has a receiving groove and an opening that are interconnected, the peripheral wall of the extension rod is provided with a plurality of screw holes, and one end of the adjustment rod is provided with There is a universal bearing, the adjusting rod is provided with a supporting part respectively relative to the screw holes, wherein the screw holes are respectively screwed with a fine-adjusting screw, and the fine-adjusting screws are respectively supported on the supporting parts, and the other end of the adjusting rod is passed through the opening and provided with a connecting part; a sight glass assembly is assembled on the connecting part, and the sight glass assembly includes an eyepiece assembly and an objective lens assembly.

The invention provides a coaxial adjustment device for the barrel sight, which lengthens the length of the coupling rod by means of the adjustment piece, and through the universal bearing and the fine-tuning screws, enables the adjustment piece and the coupling rod to achieve a coaxial and concentric effect, thereby meeting the convenience and precision requirements of various military services for direct use without removing the muzzle brake.

The adjusting rod 22 is supported against the supporting parts 222. Thus, when adjusting the precision, the adjusting rod 22 can be provided with a multi-angle rotation by fine-tuning the fine-tuning screws 223 to achieve the precision requirement. The other end of the adjusting rod 22 is passed through the opening 212 and is provided with a connecting part 224. The tensioner handle 23 is provided with a connecting part 224. At the outer side wall of the extension rod 21 and adjacent to the opening 212, when the tensioner handle 23 is rotated, the extension rod 21 and the coupling rod 10 can be rotated in conjunction, thereby expanding the coupling chuck 11 outward and being fastened in the barrel, so that the shaft coaxiality adjustment device 100 of the barrel sight will not fall off during operation and cause damage.

A sight glass assembly 30 is assembled on the assembly connection portion 224, and the sight glass assembly 30 includes an eyepiece assembly 31 and an objective lens assembly 32. The objective lens assembly 32 refracts the received image to the eyepiece assembly 31 through an optical lens assembly 33, so that the user can see the image and the crosshairs of the aiming reticle of the optical lens assembly 33 to implement precision adjustment of the gun barrel.

When using the device, the coupling rod 10 is first inserted into a barrel 200, and the muzzle coupling cone 12 is fixed to the muzzle 202. Then, the tensioner handle 23 is operated to expand the coupling chuck 11 outward, so that the coaxial adjustment of the barrel sight is achieved. The device 100 is fixed in the gun barrel 200. At this time, the extension rod 21 is located at the position of the muzzle brake 201, and the sight glass set 30 is located outside the muzzle brake 201. The user can see the image of the eyepiece set 31 through the objective lens set 32, so as to implement the muzzle position and aiming point correction of the gun barrel, and then complete the zeroing correction, which effectively improves the shooting hit rate of the armored vehicle.

The axis coaxiality adjustment device 100 of the barrel sight of the present invention lengthens the length of the coupling rod 10 by means of the adjustment member 20, so as to meet the convenience of direct use by various military services without removing the muzzle brake 201. After the adjusting member 20 is combined with the coupling rod 10, the adjusting member 20 and the coupling rod 10 are made coaxial and concentric through the universal bearing 221 and the fine-tuning screws 223 during assembly, thereby adjusting the overall accuracy of the coaxial adjustment device 100 of the barrel sight to meet the accuracy requirements, and making the coaxial adjustment device 100 of the barrel sight and the muzzle 202 coaxial and concentric during use, thereby overcoming the problem of axis deviation caused by extending the length of the sight.
