OPTICAL SIGHT OF FIRE CONTROL SYSTEM Russian patent published in 2018 - IPC F41G7/26 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of optical instrument making and concerns the optical sight of a fire control system. Sight includes a sighting and viewing channel, an aiming channel and a reconciliation device including alignment regulators of the optical axes of the guidance channel and the sighting channel. Regulators are made in the form of two pairs of swivel optical wedges with mechanical drives. Guidance channel is fixed to a support plate fastened to the body of the sight, in which holes are made for fastening elements with washers installed on both sides of the plate holes. And one fastening element is installed in the hole of the body and the washer adjacent to it without a gap, and in the hole of the plate and the upper washer – with a gap, forming a ball joint. Two other fasteners are installed in the holes of the plate and washers with a gap. In addition, a longitudinal groove is provided in the plate in the direction of the first fastening element-the hinge, into which the eccentric is mounted, in a spherical shape, so that the eccentric sphere contacts the side surfaces of the groove. Contacting support surfaces of the plate holes are conical, and the contact surfaces of the plates are spherical.

EFFECT: technical result consists in increasing the reliability of the sight, ensuring high stability of the optical axes and simplifying the alignment process.
