Abstract

The invention discloses a large-stroke high-precision zero-position adjustment mechanism, which includes an adjustment shaft, an adjustment support, an adjustment screw sleeve, an anti-rotation mechanism and a dust-proof mechanism. A dust-proof mechanism is installed on one side of the adjustment support. Anti-rotation mechanisms are installed in the mounting holes on both sides; the adjusting screw sleeve is installed in the middle of the adjusting support through the boss, the adjusting shaft is installed in the adjusting screw sleeve, and the middle part of the adjusting shaft is provided with a concave plane; the adjusting support A limit plate is installed at the bottom of the bottom, and the edge of the limit plate is in close contact with the concave plane in the middle of the adjustment shaft. The adjustment range of the zero position adjustment mechanism of the present invention can reach more than 10mm, and the adjustment shaft does not rotate during adjustment, ensuring higher adjustment accuracy and high reliability.

Description

technical field [0001] The invention relates to the field of optics, in particular to a large-stroke and high-precision zero position adjustment mechanism, which is mainly used for zero position adjustment of long-distance optical sights. Background technique [0002] At present, there are many ways to adjust the zero position of various optical sights, most of which are realized by moving the reticle, and the mechanism that promotes the movement of the reticle generally adopts the form of a thread pair, that is, the threaded sleeve is fixed, the screw rotates, and the reticle is pressed against the reticle. frame moves. In order to ensure the adjustment accuracy and reliability, the adjustment range of this type of adjustment mechanism is small, generally not exceeding 4mm, and the adjustment accuracy is high. Therefore, this type of adjustment method is often used on short-focus sights, but it cannot eliminate the accuracy change caused by screw rotation. [0003] Due to...
