Description

Technical Field

[0001] The utility model relates to the technical field of night vision devices, and particularly relates to a head-mounted night vision device. Background Art

[0002] A night vision device is a night external sight with an image intensifier as the core device. When it works, it does not use an infrared searchlight to illuminate the target, but uses the light reflected by the target under weak light to pass through the image intensifier and be enhanced into a visible image that can be sensed by the human eye on the fluorescent screen to observe and aim at the target. An infrared night vision device is a military night vision instrument using optoelectronic conversion technology, which is divided into two types: active and passive. The former irradiates the target with an infrared searchlight and receives the reflected infrared radiation to form an image; the latter does not emit infrared rays and relies on the infrared radiation of the target itself to form a "thermal image".

[0003] In the prior art, night vision devices are divided into two types: handheld and head-mounted. The head-mounted night vision device can free the user's hands to complete other tasks when worn on the head. However, the head-mounted night vision device usually cannot be adjusted and cannot be used to view with the left eye or the right eye according to the user's own needs. Content of the Utility Model

One end of the rotating frame is fixedly connected with a night vision lens. A control knob is rotatably connected to the outer side wall of the limit sleeve. A number of electromagnet blocks are evenly arranged inside the control knob. A number of rotating sleeves are fixedly connected to the outer side wall of the limit sleeve. A rotating groove is arranged inside the limit sleeve.

[0008] According to the described head-mounted night vision device, the two connecting buckles cooperate to facilitate the fixation of the two fixing straps.

[0009] According to the described head-mounted night vision device, the support headband, the limit headband and the fixing strap are all made of elastic fabric, which is convenient for stretching and improves the applicable range of the headband.

[0010] According to the described head-mounted night vision device, a telescopic belt is arranged inside the support headband to increase the telescopic range of the support headband.

[0011] According to the described head-mounted night vision device, the rotating sleeve rotates inside the rotating groove, which improves the stability of the rotation of the rotating sleeve.

[0012] According to the described head-mounted night vision device, a limit ball is slidably connected inside the rotating sleeve. A return spring is arranged between the limit ball and the rotating sleeve to facilitate the reset of the limit ball.

[0013] According to the described head-mounted night vision device, a number of limit grooves are evenly arranged on the inner side wall of the limit sleeve and on the outer circle of the rotating groove. The cooperation between the limit grooves and the limit balls can limit the rotation of the rotating shaft.
