Background

The earliest use of laser sights began with the popularization of night vision goggles, and during operation, the sights emitted a beam of near-infrared laser invisible to the naked eye, and after the optical axis was calibrated and the firearm emission axis was parallel, the laser spot drop point indicated the aiming point of the firearm to the target. The laser sighting device has the characteristics of visual observation and rapid response, and then develops the laser sighting device with visible spectrum of green laser, red laser and the like.

In recent years, with the development of laser sighting device technology and the development of firearms technology, the integration level of the laser sighting device is higher and higher, including a double-light-path system integrated with a tactical flashlight, a double-light-path system integrated with a friend or foe identification system and the like, wherein a mechanism and a method for adjusting a double optical axis are key design points of the system; meanwhile, in order to meet the development of the gun family, the requirement on the recoil resistance of the laser sighting device and the laser sighting system is higher and higher.

The traditional double-light-path integrated laser sighting device is difficult to assemble and adjust between optical axes and between the optical axis and a gun shaft, for example, in the technical scheme shown in patent document 1, the synchronous adjustment of the double optical axes is realized by using screw groups in two vertical directions, but the single optical axis cannot be accurately adjusted, the laser is low in axial fixing reliability, due to the recoil of the gun, the optical axis needs to be adjusted again after a soldier uses the laser sighting device, the use and maintenance cost is high, so that how to design a high-recoil-resistant double-light-axis mechanism on the basis of the traditional double-light-axis laser sighting device expands the range of a gun family of the laser sighting device, and the laser sighting device is valuable.

So, wholeness is strong between first optical axis part 2 and the optical axis mount pad 1, and during gun vibrations, the relative position that remains stable between first optical axis part 2 and the optical axis mount pad 1 can improve anti back seat ability to rotate along with the rotation of optical axis mount pad 1, with the correction optical axis angle.
