AI Technical Summary

Technical Problem

When shooting, existing optical scopes are prone to deformation and fracture at the zoom groove of the main lens barrel due to recoil during shooting, which poses safety hazards.

Method used

A zoom scope with a new magnification mechanism is designed, and the front and rear steering lens group movement is driven by the circumferential rotation of the inner tube to achieve magnification. The zoom pin and the magnification groove structure on the main lens barrel are abolished, and a thinner and narrower elastic connection of the shrapnel and the opening groove, circular hole and circumferential groove structure on the main lens barrel are adopted.

Benefits of technology

The smoothness of the front and rear steering lens groups during the zooming process is improved, the structural strength of the main lens tube is enhanced, the risk of deformation and fracture caused by shooting impact is reduced, and the shooting reliability and service life of the zooming tube is ensured.

Abstract

The utility model relates to a zoom sighting telescope with a novel magnification adjusting mechanism. The zoom sighting telescope comprises a main lens barrel, an outer tube, an inner tube, a field lens group, a front-back steering zoom lens group, a fixed pressing ring, a connecting elastic sheet and a magnification adjusting knob. The inner wall of the eyepiece end of the main lens cone is provided with a ball arc structure, a cylindrical pin is embedded in the middle of the arc, the eyepiece end of the outer tube is provided with a ball arc structure, the arc structure is provided with an axial straight groove, the inner tube is installed in the outer tube, the field lens group is installed in the objective lens end of the outer tube, and the front-back steering zoom lens group is installed in the inner tube. And the circumferential rotation of the inner tube can drive the front-back steering zoom lens group to move back and forth along the axial direction of the inner tube to realize zoom. The fixing pressing ring fixes the inner tube and the outer tube on the main lens barrel, the connecting elastic piece penetrates through a notch of the main lens barrel, one end of the connecting elastic piece is fixed on the inner tube, and the other end of the connecting elastic piece is connected with the magnification adjusting knob which is sleeved on the main lens barrel. The limitation that the rotation angle of an existing sighting telescope zoom tube is generally about 180 degrees is overcome, the rotation angle of an inner tube zoom rotation curve groove can reach 360 degrees, and the design difficulty of a sighting telescope zoom system is lowered.
