Structure for screw zero limiting, self-locking and adjusting

Abstract

The invention provides a structure for screw zero limiting, self-locking and adjusting. The structure comprises a base, a rotating part and a top cover, a connecting ring is arranged on the base, adjusting scales are arranged on the inner side of the connecting ring, a first mounting hole is formed in the outer side of the connecting ring, a self-locking assembly is arranged in the first mounting hole, a mounting groove is formed in the rotating part, and an adjustment screw penetrating through the base is arranged in the mounting groove. A connecting groove corresponding to and cooperating with the connecting ring is formed in the bottom of the rotating part, a second mounting hole and a third mounting hole are formed in the inner side and the outer side of the connecting groove correspondingly, and an adjustment assembly and a pressing assembly are arranged in the second mounting hole and the third mounting hole correspondingly. The adjustment assembly and the adjusting scales are in cooperation to carry out adjusting operation of a sighting telescope, the self-locking assembly and the pressing assembly are used for zeroing and self-locking, the rotating part is prevented from rotating at will, the rotating part is kept in a zeroing state, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of scopes, in particular to a structure of a zero-limiting self-locking adjustment screw. Background technique [0002] The origin of sights, or optical sighting devices, is difficult to trace. It is said that at least in Europe in the 16th century, someone had tried to fix spectacle lenses on the butt of a gun. According to written records, before the 19th century, there were telescopic aiming devices on firearms, which can be used for aiming in low light conditions. Sights can be divided into holographic sights, inner red and green dot sights, and laser sights. Up to now, sights are mainly divided into the following three categories: telescopic sights, collimating sights, and reflex sights. Among them, telescopic sights and reflex sights are the most popular. [0003] The scope adjustment device is a device used to adjust the scope. It plays a very important role in the use of the scope. The principle ...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes a zero-limiting self-locking adjustment screw structure to solve the problem that the existing scope proposed in the background technology has no zero-limiting device, and a slight collision will easily make the adjustment device rotate and move, so that the scope deviates from the zero position. Not conducive to the preservation of the scope and other issues
