Embodiment Construction

[0064] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] see figure 1 , the present invention is a three-field switching mechanism for optical equipment, including a main frame assembly, a rotating lens barrel assembly, a driving assembly 16 and a limit assembly.

[0066] The above-mentioned main frame assembly includes the main frame 1 . In this embodiment, for the sake of simple processing and cost saving, the main frame 1 preferably adopts a box structure, which is a rectangular frame, and its upper and lower sides are opened to facilitate the installation of the rotating lens barrel 5 . The main frame assembly in this embodiment also includes an upper cover plate 2 and a lower cover plate 3; the upper cover plate 2 and the lower cover plate 3 are respectively covered on the upper and lower surfaces of the main frame 1, are fixedly connected with the main frame 1, and surround into a ca...

Abstract

The invention relates to a field of view switching mechanism for optical equipment, in particular to a three-field switching mechanism for optical equipment. The positioning accuracy cannot meet the use requirements. The special feature of this switching mechanism is that it includes the main frame assembly, the rotating lens barrel assembly and the limit assembly located in the main frame, and also includes the driving assembly; the rotating lens barrel assembly includes the rotating lens barrel, which is installed around the rotating lens barrel clockwise Switching mirror group 1, switching mirror group 4, hood, switching mirror group 2, and switching mirror group 3 to the side are fixedly connected to the first inner shaft and the second inner shaft at both ends of the rotating lens barrel and rotatably connected with the main frame respectively. Shaft; the peripheral side of the rotating lens barrel is provided with a light hole; the switching mirror group one and the switching mirror group two, the switching mirror group four and the switching mirror group three, the hood and the light hole are respectively coaxial; the limit assembly includes two sets A magnet limit assembly and a set of plunger limit assemblies.

Description

technical field [0001] The invention relates to a visual field switching mechanism for optical equipment, in particular to a three visual field switching mechanism for optical equipment. Background technique [0002] The ship-borne photoelectric theodolite is mainly used for real-time tracking and measurement of fast targets, and the visible light TV measurement system is an important part of it. With the diversification of work task requirements, the visible light imaging system is required to have a multi-field of view switching function, so that it can detect longer-distance targets in the long-focus small field of view, and at the same time conduct a large-scale search in the short-focus large field of view, so as to realize Accurate tracking and capture of targets. [0003] The switching of the field of view is to control the movement of the corresponding lens group of the optical system to cause the change of the focal length, thereby realizing the change of the field...
