Description

Technical Field

[0001] The utility model relates to the technical field of sights, in particular to a low-light night vision sight. Background Art

[0002] The origin of the sight, or optical aiming device, is difficult to verify. It is said that at least in Europe in the 16th century, people had tried to fix eyeglass lenses on the buttstock. There are written records that before the 19th century, there were telescopic aiming devices on firearms, which could be used for aiming in low light conditions. Usually, sights are mainly used during the day, so they are collectively called daylight sights. In addition, there are night vision sights for night aiming, which are night vision devices added to the above two types of sights. According to the type of night vision device, it can be divided into low light sights and infrared sights.

[0003] The Chinese patent with patent announcement number CN211903927U discloses a low-light-level night vision laser sight, which relates to the field of sight technology, including an objective lens barrel, a low-light enhancement barrel, an eyepiece barrel, a laser emitter and a laser controller, wherein the right end of the objective lens barrel is threadedly connected to the left end of the low-light enhancement barrel, the right end of the low-light enhancement barrel is threadedly connected to the left end of the eyepiece barrel, the outer wall of the low-light enhancement barrel is fixedly connected to the outer wall of the laser controller, and the bottom of the laser controller is fixedly connected to the outer wall of the laser emitter. The low-light-level night vision laser sight can observe the environment under low light through the low-light enhancement barrel, the laser emitter actively emits a laser beam, and the laser signal receiver receives the emitted laser signal to determine the distance, and the electric signal transmitter emits an electric signal to the electric signal receiver, and the detected distance is displayed on a micro display. In a completely dark environment, the laser that can be actively emitted can also be captured by the low-light enhancement barrel to achieve a fully functional effect.

[0004] However, the connection between the low-light-level night vision sight and the platform in the prior art is relatively unstable, resulting in poor aiming accuracy and affecting the use of the user. In order to overcome these disadvantages, the utility model provides an assembled sight. In order to overcome these disadvantages, the utility model provides a low-light-level night vision sight.
