The screen clamping plate 4 is arranged to be assembled or disassembled with the screen mounting bracket 3, and is arranged to be in contact with the display module 2. The screen clamping plate 4 is used to apply force to fix the display module 2.

[0023] The aforementioned eyepiece screen assembly used in the thermal imager, with the cooperation of the screen mounting bracket 3 and the screen pressing plate 4, enables the assembly and use of the display module 2 and the eyepiece module 1, facilitating the thermal image presentation of the thermal imager. Simultaneously, the screen mounting bracket 3 positions and reinforces the display module 2, enhancing its stability and reducing the risk of shaking or shifting. The screen pressing plate 4 further reinforces the display module 2, greatly enhancing its stability and ensuring normal operation of the thermal imager. Furthermore, by disassembling the screen mounting bracket 3 from the eyepiece module 1, the display module 2 can be directly removed without easily damaging it, facilitating maintenance and replacement, reducing the need for parts replacement, and lowering the operating cost of the thermal imager.

[0024] The screen mounting bracket 3 includes a main mounting bracket 31 and a fixed mounting ring 32. The main mounting bracket 31 is used to mount the display module 2.
