Abstract

The invention discloses an adjusting screw mechanism. The mechanism is characterized in that a gasket is fixedly arranged on an adjusting screw, a flat tail of the adjusting screw is arranged in a square hole of an inner adjusting handle, a pin is arranged in the inner adjusting handle and is matched into a waist-shaped hole of the adjusting screw, and the pin is fixed to the inner adjusting handle by tightening a screw. A positioning spring, a positioning pin and a steel ball are sequentially arranged in a blind hole of the inner adjusting handle, the spring tightly presses the positioning pin, the steel ball placed in a positioning pin hole makes contact with a triangular inner tooth bevel groove of a hand wheel base, external threads of the adjusting screw for assembly are in threaded connection with internal threads of the hand wheel base, external threads of a hand wheel check ring are in threaded connection with the internal threads of the hand wheel base, the inner adjusting handle is limited, and the hand wheel check ring is fixed to the hand wheel base by tightening a screw, an outer adjusting handle is fixed to the inner adjusting handle by tightening a screw, an inner sealing ring is arranged between the hand wheel base and the inner adjusting handle, and an outer sealing ring is arranged between the hand wheel base and the outer adjusting handle. The mechanism has the advantages of being easy to assemble, good in stability, convenient to use and high in precision.

Description

technical field [0001] The invention belongs to the technical field of scope manufacture, and in particular relates to an adjusting screw mechanism. Background technique [0002] At present, in order to improve the shooting accuracy of guns, an optical sight is generally used to add it. Due to the uncertainty of environmental factors, the scope needs to be calibrated and adjusted during the actual shooting process. That is, the ballistic and wind direction are adjusted through the screw adjustment mechanism to achieve accurate shooting. The screw adjustment mechanism is therefore an extremely important component for the scope. Although the adjusting screw mechanism on the market today can adjust the ballistic and wind direction, since there is no screw downward limit mechanism, improper operation will lead to screw misalignment, poor stability after use, and low precision. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
