DETAILED DESCRIPTION

[0022] The following describes several preferred embodiments of the present invention with reference to the drawings in the specification, so that the technical content is clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

[0023] In the drawings, components with the same structure are indicated by the same numerical reference numerals, and components with similar structures or functions are indicated by similar numerical reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

[0024] Combination Figure 1 , Figure 2 , Figure 3 As shown, an infrared imaging device based on a micrometer adjustment mechanism provided by an embodiment includes a lens barrel 1, the lens barrel 1 has an accommodating space 2, and an optical window 3 is provided on the lens barrel; a support assembly 4 is provided in the accommodating space; an infrared imaging lens 5 and an infrared image receiver 6 are installed on the support assembly 4, wherein the infrared imaging lens 5 corresponds to the optical window 3 to receive infrared light entering through the optical window 3, and the infrared image receiver 6 corresponds to the infrared imaging lens 5 to image the infrared light passing through the infrared imaging lens 5. Specifically, the support assembly 4 includes a heat-conducting base 44, a T-shaped heat-conducting bottom plate 42, a mounting bottom plate 43, a first mounting bracket 41, and a second mounting bracket 45, the heat-conducting base 44 is slidably matched with the lens barrel 1, the T-shaped heat-conducting bottom plate 42 is arranged on the heat-conducting base 44 and slidably matched with the heat-conducting base 44, the mounting bottom plate 43 is fixedly attached to the T-shaped heat-conducting bottom plate 42, and the first mounting bracket 41 and the second mounting bracket 45 are vertically fixed on the mounting bottom plate 43. Preferably, the first mounting bracket 41 and the second mounting bracket 45 are respectively placed on both sides of the infrared image receiver 6; the second mounting bracket 45 is placed between the infrared imaging lens 5 and the infrared image receiver 6. A silent DC fan 8 is installed on the side of the first mounting bracket 41 and the second mounting bracket 45 facing the infrared image receiver 6, which is used to cool the infrared image receiver 6 and can cooperate with the heat-conducting base 44 to achieve a relatively low temperature in the working environment of the infrared imaging device, thereby extending the service life.

[0025] like Figure 2 , Figure 3As shown, the image quality adjustment mechanism 9 is also installed on the support assembly 4 and is placed at the end of the support assembly 4 away from the optical window 3. The image quality adjustment mechanism 9 includes an adjustment block 91 and a micrometer head 92. The adjustment block 91 is installed on the support assembly 4 by screws. Specifically, the adjustment block 91 is fixed to the heat-conducting base 44 by screws, and the micrometer head 92 is installed on the adjustment block 91 by locking screws. A limit screw 7 is installed at one end of the support assembly 4 close to the optical window 3. Specifically, the limit screw 7 is installed at one end of the heat-conducting base 44 close to the optical window 3 to prevent the lens from moving a large distance and colliding with the window glass. When adjusting the image quality, the rotating micrometer head 92 pushes the T-shaped heat-conducting bottom plate 42 to slide, driving the entire machine movement to slide, thereby achieving clear image quality of the infrared camera device. At the same time, the micrometer head 92 can read the size of the fine-tuning distance, thereby solving the problem that it is difficult to accurately fine-tune the image quality when the infrared camera body is placed inside the lens barrel in the prior art, resulting in unclear image quality.
