Abstract

The invention relates to the technical field of night vision equipment and specifically relates to a night vision device based on a helmet. The night vision device comprises a storage cavity at the top of the helmet, wherein a night vision device body is arranged in the storage cavity, a power spring is arranged at the end of the storage cavity, a first supporting shaft penetrates through the middle of the power spring, the two ends of the first supporting shaft are connected with the storage cavity, a connection belt and a ratchet wheel are further arranged on the first supporting shaft, a pawl is arranged under the ratchet wheel, and the connection belt is connected with the night vision device body. The night vision device body comprises a night vision device body outer shell, wherein an infrared transmitting tube, a first lens cone and a second lens cone are arranged in the night vision device body outer shell, and an objective lens, a photoelectric negative electrode, a microchannel plate, a display screen and an adjusting mechanism are respectively arranged in the first lens cone and the second lens cone. According to the night vision device disclosed by the invention, the storage cavity is arranged at the top of the helmet; in usual, the night vision device body is stored in the storage cavity; when the night vision device body is used, a convex block at the top of the night vision device body outer shell is held by hand to downwards pull the night vision device body out of the storage cavity; thus, the night vision device body can be quickly storage and opened; furthermore, the pupil distance and the heights of the lens cones can be finely adjusted.

Description

technical field [0001] The invention relates to the technical field of night vision equipment, in particular to a helmet-based night vision equipment. Background technique [0002] Night vision device is an important equipment for people to carry out activities at night, and it plays an important role in both military and civilian use. The traditional night vision device is only equipped with one lens barrel, and people can only observe the situation on one side when working. When it is necessary to observe the situation in a wider area, the night vision device cannot meet the work requirements, and the traditional night vision device is not set. Helmet, when working, you need to manually hold the night vision device to observe. When you need to do other tasks manually, people can't use the night vision device, and the traditional night vision device is not equipped with a goggle cover, so it takes a long time to use In the future, the surface of the objective lens will be ...
