[0002] In the field of modern optoelectronic technology, riflescopes play a key role in many fields such as hunting, competitive shooting, military operations, and security monitoring. With the rapid development of science and technology, digital riflescopes have gradually emerged in the market with their excellent functional characteristics and have become the focus of industry attention. However, although different types of digital riflescopes have different functional focuses, they face the problem of lack of versatility and flexibility in the adjustment mechanism. Users who are accustomed to using traditional white light riflescopes find it difficult to adapt to the button operation habits of existing digital riflescopes when switching to digital riflescopes, which reduces aiming efficiency and poor user experience. In order to meet the operating habits of specific users and at the same time improve the compatibility of the adjustment mechanisms of different types of digital riflescopes, it is urgent to develop a digital riflescope adjustment mechanism that combines the operating characteristics of white light riflescopes.

[0004] To solve the above technical problems, the present invention provides an adjustment mechanism for a digital sight, comprising an encoder group and a zoom group; the encoder group comprises two rotary encoders, which are arranged on the outside of the digital sight and are arranged perpendicular to each other; the zoom group is arranged on the circumference of the digital sight, and has a rotating structure and a rotating sensing structure; When the rotary encoder is rotated, the digital sight adjusts the position of the scale center according to the output signal of the rotary encoder; when the magnification group is rotated, the rotary sensing structure senses the rotation amount and outputs an electrical signal, and the digital sight changes the magnification according to the electrical signal output by the rotary sensing structure.

[0005] According to the above solution, the rotary encoder has a locking structure, and the rotary encoder cannot be rotated when locked.

[0006] According to the above scheme, the rotary encoder includes an encoder seat, an encoder pressure ring, a gear disc, an encoder plate, an encoder handwheel, and a handle transmission block; the encoder seat is connected to the outside of the digital sight, the bottom fixed end of the encoder plate is connected to the encoder seat, the encoder pressure ring is located above the encoder seat and is connected to the bottom fixed end of the encoder plate, the gear disc is located above the encoder pressure ring, the encoder handwheel is sleeved on the encoder seat and the outside of the gear disc, and the encoder handwheel is connected to the gear disc, the top movable end of the encoder plate is connected to the handle transmission block, the handle transmission block is located on the inside of the gear disc and is transmission-connected to the gear disc; When locking is required, press the encoder handwheel downward, and the encoder handwheel drives the gear plate to move downward. The gear plate and the encoder pressure ring cooperate with each other to lock. At this time, the encoder pressure ring and the encoder handwheel cannot rotate; When unlocking is required, the encoder handwheel is lifted, and the encoder handwheel drives the gear disc to move upward, and the gear disc and the encoder pressure ring are unlocked. At this time, the encoder pressure ring and the encoder handwheel can be rotated. When the encoder pressure ring rotates, it drives the handle transmission block to rotate, and the handle transmission block drives the top movable end of the encoder plate to rotate.
