Abstract
The invention discloses a day-night switching positioning mechanism comprising a center shaft and a day-night support. The day-night support is provided with a sector gear and a positioning ring. One side of the sector gear is provided with a transition gear and a transmission gear which are installed on the panel of an aiming system, and the other end of a transmission shaft is provided with a hand wheel. The positioning ring is provided with two positioning V-shaped grooves. The central angle of the two positioning V-shaped grooves is equal to the central angle of a night channel mechanism and a daytime channel mechanism. One side of the positioning ring is provided with a positioner and a spring which acts on the positioner. The positioner and the positioning ring are abutted. When the night channel mechanism works, the positioner is close to the positioning V-shaped groove corresponding to the work position of the night channel mechanism. When the daytime channel mechanism works, the positioner is close to the positioning V-shaped groove corresponding to the work position of the daytime channel mechanism. Transformation between day and night can be realized, and consistency after transformation of the optical axis can be guaranteed so that day and night observation, tracking and aiming of a modern precise photoelectric instrument for a target can be realized.
